Endoscopy for acute nonvariceal upper gastrointestinal tract hemorrhage: is sooner better? A systematic review.

BACKGROUND: While the effectiveness of upper endoscopy has been established for acute nonvariceal upper gastrointestinal tract hemorrhage, its optimal timing has not been clearly defined. Early endoscopy has been advocated for its ability to achieve prompt diagnosis, risk stratification, and therapeutic hemostasis. OBJECTIVE: To determine whether early vs delayed endoscopy improves patient and economic outcomes for all risk groups with nonvariceal upper gastrointestinal tract hemorrhage. METHODS: A systematic review of 3 computerized databases (MEDLINE, HEALTHSTAR, and Cochrane Database of Systematic Reviews) was performed along with hand searching of published abstracts to identify English-language citations from 1980 to 2000. RESULTS: Twenty-three studies met explicit inclusion criteria. The highest-quality study examining outcomes in low-risk patients found no significant complications at 1-month follow-up for any outpatients managed with early endoscopy. The largest randomized trial of high-risk patients showed no mortality benefit but a significant decrease in transfusion requirements with early endoscopy. Seven of the 8 studies examining the effect of early endoscopy on length of stay as a measure of resource utilization demonstrated a significant reduction compared with that of delayed endoscopy. However, most included studies were found to suffer from 1 or more potentially significant methodologic shortcomings. CONCLUSIONS: The overwhelming majority of existing data suggest that early endoscopy is safe and effective for all risk groups. The clinical and economic outcomes of early endoscopy should be confirmed in additional well-designed randomized controlled trials. Given the strength of the evidence, efforts to develop a more standardized and time-sensitive approach to acute nonvariceal upper gastrointestinal tract hemorrhage should be undertaken.

Increased diagnostic yield of small bowel tumors with capsule endoscopy.

BACKGROUND: It is believed that cancers of the small intestine represent <2% of all malignant tumors of the gastrointestinal tract, although the accuracy of this estimate is unknown, because the current methodologies for examining the small bowel have proved inadequate. Capsule endoscopy allows a more detailed inspection of the small intestine and may improve the ability to diagnose small bowel tumors. The objective of this study was to evaluate the effectiveness of capsule endoscopy in diagnosing small bowel tumors and to help establish the true incidence of tumors in obscure gastrointestinal bleeding. METHODS: A retrospective analysis of the charts of 562 patients who underwent capsule endoscopy from August 2001 to November 2003 for a variety of indications was performed. The indication for the procedure was bleeding (alone or in addition to another indication, such as abnormal imaging) in 443 patients. RESULTS: A diagnosis was made by capsule endoscopy in 277 patients (49.3%). Of 562 patients who were included in the study, 50 patients (8.9%) were diagnosed with small bowel tumors. The types of tumor diagnosed by capsule endoscopy included 8 adenocarcinomas (1.4%), 10 carcinoids (1.8%), 4 gastrointestinal stromal tumors (0.7%), 5 lymphomas (0.9%), 3 inflammatory polyps, 1 lymphangioma, 1 lymphangioectasia,1 hemangioma, 1 hamartoma, and 1 tubular adenoma. Of the tumors diagnosed, 48% were malignant. It was observed that 9 of 67 patients (13%) younger than age 50 years who underwent capsule endoscopy for obscure bleeding had small bowel tumors. The pathology results were not available for 10 patients. CONCLUSIONS: Capsule endoscopy diagnosed small bowel tumors in 8.9% of patients who underwent the procedure for a variety of reasons, establishing it as an effective diagnostic modality. This incidence of small bowel tumors suggests an important role for capsule endoscopy in the algorithm for the diagnostic work-up of patients with suspected small bowel lesions. Capsule endoscopy may lead to earlier detection and treatment of small bowel tumors and an improved prognosis for patients with these neoplasms.

Utility of intraoperative endoscopy: implications for surgical education.

BACKGROUND: The use of intraoperative endoscopy by surgeons can identify pathology and help determine the appropriate procedure to perform. However, residency training in endoscopy is often variable and unstructured. The purpose of this study was to determine the indications for and impact of intraoperative endoscopy performed at the time of general surgical procedures. METHODS: The records of all patients who underwent intraoperative endoscopy from January 1998 to December 1999 were reviewed. The indications for endoscopy, endoscopic findings, the impact of these findings on the operation performed, complications, and whether the patient was spared from undergoing a second procedure on a separate date were noted. RESULTS: A total of 107 intraoperative endoscopic procedures were performed in 103 patients. Excluding breast, endocrine, central line, and peritoneal dialysis catheter cases, endoscopy was utilized in 5.1% of all general surgery procedures performed during this time period. In 91 patients (88%), the endoscopic procedure was planned preoperatively; in 13 (12%), intraoperative findings dictated its use. The most common indications for endoscopy were identification of lesions and determination of extent of resection (n = 27); evaluation of rectal bleeding (n = 21); colonic evaluation in patients with perianal infections (n = 13); evaluation of extent of injury in trauma cases (n = 8); evaluation of pain (n = 6); evaluation of intestinal tract hemorrhage (n = 6); performance of procedures such as placement of a biliary stent, placement of a nasojejunal tube, or polypectomy (n = 5); and surveillance of chronic disease (n = 5). In 37 patients (36%), the endoscopic findings affected the operation performed. Sixty-nine patients (67%) were spared an endoscopic procedure at a second date, which would have required additional sedation or anesthesia. There were no complications related to endoscopy. CONCLUSION: Intraoperative endoscopy is a valuable tool that can be performed safely for multiple indications and is frequently of value in determining the operation to be performed. Surgical residents should be trained in the indications for endoscopic evaluation as well as the competent performance of such procedures.

Capsule endoscopy: an alternative to duodenal biopsy for the recognition of villous atrophy in coeliac disease?

BACKGROUND: Villous atrophy present on a duodenal biopsy remains the 'gold standard' diagnostic test for coeliac disease. However, endoscopic biopsy may cause morbidity and discomfort. Our aim was to evaluate wireless capsule endoscopy as an alternative test for the recognition of villous atrophy. METHOD: Twenty-one patients with a positive endomysial antibody referred for endoscopy and duodenal biopsy were also offered a wireless capsule endoscopy to evaluate their small bowel. Concurrently, other patients (n=23) referred for a wireless capsule endoscopy acted as controls. Wireless capsule endoscopy reports were assessed for the presence of villous atrophy by one blinded investigator. RESULTS: Twenty endomysial antibody positive patients subsequently had villous atrophy on duodenal biopsy. The controls all had normal duodenal biopsies (with a negative endomysial antibody) and no evidence of villous atrophy noted on their wireless capsule endoscopy. Of the 20 endomysial antibody positive patients with confirmed villous atrophy on biopsy, 17 had villous atrophy also detected by wireless capsule endoscopy. The sensitivity, specificity, positive and negative predictive values for wireless capsule endoscopy recognising villous atrophy were 85%, 100%, 100%, 88.9%, respectively. CONCLUSION: Wireless capsule endoscopy may be an option to recognise villous atrophy in patients with a positive endomysial antibody who are unwilling, or unable to have a gastroscopy. However, a negative test should be followed by a biopsy if coeliac disease is to be excluded.

Clinical outcome of patients examined by capsule endoscopy for suspected small bowel Crohn's disease.

BACKGROUND: Capsule endoscopy has a greater diagnostic yield than radiology for detecting subtle inflammatory changes of the small bowel mucosa, but the clinical significance of these abnormalities is still uncertain because of the lack of long-term follow-ups. AIM AND METHODS: To verify the accuracy of capsule endoscopy in a cohort of patients with suspected Crohn's disease of the small bowel, taking as 'gold standard' the final diagnosis made after a long follow-up. From April 2002 to March 2005, we enrolled and examined by capsule endoscopy 27 consecutive patients with abdominal pain and diarrhea lasting more than 3 months and at least one of the following: anaemia, weight loss, fever, extra-intestinal manifestation(s) of inflammatory bowel disease. All patients already had an unremarkable pan-endoscopy, serology for celiac disease and intestinal radiology inconclusive for small bowel abnormality. On the basis of capsule endoscopy findings, patients were distributed in three groups; Group A had severe stricturing lesions requiring surgery; Group B, moderate inflammatory lesions further investigated invasively; Group C, minimal inflammatory changes or normal findings, clinically observed every 3 months (median 21 months, range 15-29). RESULTS: Small bowel inflammatory lesions were found in 16 of the 27 patients (diagnostic yield 59%). Three had surgery (Group A) and Crohn's disease was confirmed in two; the remainder had ileal adenocarcinoma in a pathological context of chronic inflammation. Crohn's disease was histologically confirmed in four of the five patients in Group B. Group C comprised 19 patients; Crohn's disease was confirmed in seven out of eight with positive capsule endoscopy, while only one of the patients with normal findings later developed overt ileal Crohn's disease. Sensitivity, specificity, positive and negative likelihood ratio were, respectively, 93%, 84%, 5.8 and 0.08. Assuming a 50% pre-test probability of disease, capsule endoscopy gave a post-test probability of 85%. CONCLUSIONS: In our selected cohort, capsule endoscopy was highly sensitive in detecting small bowel inflammatory changes, enhancing by nearly 35% the pre-test probability of structural small bowel disease. Focal erythema and luminal debris may limit the specificity of capsule endoscopy.

Acetic acid-guided biopsies after magnifying endoscopy compared with random biopsies in the detection of Barrett's esophagus: a prospective randomized trial with crossover design.

BACKGROUND: In contrast to standard video endoscopy, magnifying endoscopy after local acetic acid application enables recognition of mucosal surface architecture. OBJECTIVE: To investigate the diagnostic yield of magnifying endoscopy with acetic acid-targeted biopsies compared to random, 4-quadrant biopsies. DESIGN: Prospective randomized trial (ratio 1:1) with crossover design. SETTING: Two referral hospitals in Germany. PATIENTS: Thirty-one patients with Barrett's esophagus or visible columnar-lined lower esophagus. INTERVENTIONS: Patients were randomized to undergo either standard video endoscopy with 4-quadrant biopsies or magnifying endoscopy in conjunction with acetic acid application. All patients were re-examined 14 days after the initial endoscopy with the corresponding procedure. MAIN OUTCOME MEASUREMENTS: Primary outcome analysis (per protocol and per biopsy) was the histological proof of Barrett's epithelium. Secondary outcome analysis was the correlation between the surface architecture and the presence of Barrett's epithelium and the needed number of biopsies to confirm Barrett's epithelium for the 2 different procedures. RESULTS: Magnifying endoscopy enabled the prediction of Barrett's epithelium with a sensitivity of 100% and a specificity of 66%, respectively (accuracy 83.8%). Acetic acid-guided biopsies obtained a significantly higher percentage of tissues containing SCE (78%; 188/241) compared to random biopsies (57%; 159/280). LIMITATIONS: No data on the diagnosis of Barrett's dysplasia. CONCLUSION: Magnifying endoscopy with acetic acid-guided biopsies is superior to standard video endoscopy with random biopsies, and the number of biopsies needed to confirm Barrett's epithelium is half as much when compared to random biopsies.

The ASGE guidelines for the appropriate use of upper gastrointestinal endoscopy in an open access system.

AIMS: This multicenter and prospective study was aimed at examining the appropriate use of upper gastrointestinal endoscopy in an open access system (primary endoscopy) using the American Society for Gastrointestinal Endoscopy (ASGE) guidelines. We also wished to see whether these guidelines can be easily used in clinical practice. MATERIALS AND METHODS: Three thousand four hundred fourteen upper gastrointestinal endoscopies performed in seven endoscopy units of different size were studied prospectively. The real indication, to be with the guidelines, was determined by the endoscopist before performing the examination, based on a patient's history. RESULTS: Seven hundred eighty-one (23%) endoscopies were "generally not indicated," according to ASGE guidelines, and were distributed as follows: follow-up of duodenal ulcer healing (33%), follow-up of other healed benign diseases (24%), surveillance of gastric atrophy, pernicious anemia, metaplasia, treated achalasia, and prior gastric intervention (14%), diagnosis of dyspepsia considered functional in origin (13%), and uncomplicated heartburn responding to medical therapy (7%). Endoscopies "generally not indicated" accounted for 23% in the bigger endoscopy units, 24% in the average sized units, and 22% in the smaller ones. They accounted for 32% when the examination was prescribed by family doctors, 17% when prescribed by internists, 19% by surgeons, and 14% by gastroenterologists (p < 0.001). Eighty-six (2.5%) endoscopies were done for indications not provided in the guidelines. CONCLUSIONS: This study shows that ASGE guidelines are complete and easy to use and that the rate of inappropriate indications in an open access system can be considerable. They occurred mainly in the follow-up of healed benign disease and were more frequent when the examination was prescribed by the family doctor.

Prevalence of open-access gastrointestinal endoscopy in the United States.

OBJECTIVE: Open-access endoscopy allows physicians who are not gastroenterologists to directly schedule patients for endoscopic procedures without having them first seen in the gastrointestinal clinic. We sought to determine the prevalence of open-access endoscopy in the United States and to examine endoscopists' attitudes toward the practice. METHODS: Questionnaires were mailed to a random sample of 1500 members of the American Society for Gastrointestinal Endoscopy. Out of 1460 that apparently reached the endoscopist, 577 (39.5%) were returned and analyzed. RESULTS: Of the endoscopists who responded, 60.5% said that they offered some form of open-access endoscopy. Open-access endoscopy comprised less than 10% of outpatient endoscopic practice for 48.2% of individuals who reported they offered the service; it comprised over 25% of practice in 19.8%. Of those doing it, the procedures offered on an open-access basis included esophagogastroduodenoscopy 86.0%, colonoscopy 76.5%, flexible sigmoidoscopy 94.3%, ERCP 7.7%, and endoscopic ultrasonography 4.3%. For endoscopists not offering open-access endoscopy, the most important reasons were concern about performing "not indicated" procedures (85.1 %), medical-legal issues (65.8%), and failure to believe in the concept of open-access endoscopy (59.6%). Attitudes toward open access endoscopy were significantly different among endoscopists who did and did not practice it. CONCLUSIONS: Open-access endoscopy, offered by more than 60% of the American endoscopists who responded to our survey, has become an important method of health care delivery in this country.

Health-related anxiety and the effect of open-access endoscopy in US patients with dyspepsia.

BACKGROUND: The role of endoscopy in dyspepsia is the subject of debate. The detection of lesions is infrequent, but patients may benefit from the knowledge that the examination is normal. We sought to determine the prevalence of health-related anxiety in dyspeptic patients referred for open-access endoscopy and to investigate the effect of endoscopy on health-related anxiety. METHODS: Consecutive patients referred for open-access endoscopy from primary care were studied using a validated questionnaire for health-related anxiety before and after endoscopy, at 1 month and 6 months. Symptoms were assessed using a validated questionnaire at 1 and 6 months. RESULTS: One hundred and nine patients were studied (69 women and 40 men; mean age, 49 +/- 15 years). Thirty-six of the 109 patients (33%) had high anxiety scores at baseline (mean score, 41 +/- 1), which decreased after endoscopy to 35 +/- 1 (P < 0.05). The changes persisted at 1 month (33 +/- 1) and 6 months (33 +/- 1). Endoscopic findings were as follows: normal examination, 120; erosive oesophagitis, 11 (Grade A); erosive duodenitis (all Helicobacter pylori-negative), 6. Scales for preoccupation with health and fear of illness and death showed significant improvement after endoscopy, and the effects were preserved for 6 months. Anxiety scores in our population were substantially higher than in a corresponding UK population. CONCLUSIONS: Health-related anxiety is common in dyspeptic patients referred for endoscopy. Endoscopy decreases the preoccupation with health and fear of illness and death in patients with severe anxiety, and the effects persist for 6 months.

Review article: The advent of capsule endoscopy--a not-so-futuristic approach to obscure gastrointestinal bleeding.

Capsule endoscopy is a new, wireless, endoscopic examination of the small intestine. To date, two small clinical trials have been reported utilizing capsule endoscopy in patients with obscure gastrointestinal bleeding, and have shown its superiority to push enteroscopy in diagnosing the cause of blood loss. No outcome studies have been reported. This paper proposes a change in practice guidelines for obscure bleeding. It is our opinion that, in the future, with the advent of wireless capsule endoscopy, the evaluation of patients with obscure gastrointestinal bleeding will be very different from the practice of medicine today. We believe that capsule endoscopy will become the first-line method for the evaluation of patients with obscure bleeding, once upper endoscopy and colonoscopy have been shown to be negative. In patients with active bleeding, capsule endoscopy will confirm the small bowel as the site of bleeding, providing a location, or, if the study is negative for the small intestine, may indicate that the bleeding is either colonic or gastric in origin. In a patient with active bleeding within the small intestine, the capsule will guide further evaluation and therapy. A patient with a small bowel tumour detected by capsule endoscopy will proceed directly to laparoscopic surgery. If the site of bleeding is identified in the proximal small bowel and there is no mass, push enteroscopy will be used to re-identify the site and cauterize it. A distal small bowel site will require surgical intervention, coupled with intra-operative enteroscopy. Should the patient be too sick to undergo surgery, medical therapy utilizing hormonal agents will be considered. A colonic site will be evaluated by colonoscopy. In patients with a more occult or intermittent type of bleeding and in those whose upper endoscopies and colonoscopies are negative, capsule endoscopy will be used similarly to identify a bleeding lesion and thereby direct subsequent testing or treatment.

Video capsule endoscopy in peutz-jeghers syndrome: a blinded comparison with barium follow-through for detection of small-bowel polyps.

BACKGROUND AND STUDY AIMS: Video capsule endoscopy has shown promise for the surveillance of significant small-bowel polyps in patients with Peutz-Jeghers syndrome. In this study the yield of significant small-bowel polyps by capsule endoscopy was compared to the yield of these polyps by barium follow-through in adults with Peutz-Jeghers syndrome. PATIENTS AND METHODS: A total of 19 adults with Peutz-Jeghers syndrome who were undergoing surveillance underwent both capsule endoscopy and barium follow-through examinations, and the number of small-bowel polyps of at least 1 cm in diameter that were detected was recorded for each method. The two methods were assessed in terms of comfort and convenience for the patients and their preferred future surveillance method, using a questionnaire. RESULTS: Capsule endoscopy detected a median of four significant small-bowel polyps while barium follow-through detected a median of one (P = 0.008). There was a trend towards more participants having at least one significant small-bowel polyp detected by capsule endoscopy than was the case with barium follow-through, though capsule endoscopy seemed to be less reliable for accurate sizing of polyps that were at the limit of clinical significance. Most participants expressed a preference for capsule endoscopy for future surveillance. CONCLUSIONS: Capsule endoscopy should replace barium follow-through for the surveillance of small-bowel polyps in adults with Peutz-Jeghers syndrome, but the findings of this study should be interpreted with caution until a more reliable means of sizing polyps by capsule endoscopy is available.

A randomized controlled trial comparing the accuracy of general diagnostic upper gastrointestinal endoscopy performed by nurse or medical endoscopists.

BACKGROUND AND STUDY AIMS: Rising demand for general diagnostic upper gastrointestinal endoscopy in the UK is outgrowing the capacity of doctors to provide this service within a reasonable time. One solution is to train nurses to carry out the procedure, but it is not known whether nurses can perform general diagnostic upper gastrointestinal endoscopy as competently as doctors. PATIENTS AND METHODS: A randomized controlled non-inferiority trial compared the adequacy and the accuracy of diagnostic upper gastrointestinal endoscopies performed by five medical and two nurse endoscopists. The videotaped procedures were assessed by a consultant gastroenterologist blinded to the identity of the endoscopist. RESULTS: 641 patients were randomly allocated (before attendance and consent procedure) to endoscopy carried out either by a doctor or a nurse. Of these, 412 were enrolled and 367 (89 %) were included in the analysis. An adequate view was obtained throughout in 53.4 % (93/177) of doctor endoscopies and 91.6 % (174/190) of nurse endoscopies (difference 38.2 %, 95 % CL 30.5 %, 47.2 %). In adequately viewed areas, the mean agreement between doctor and expert was 81.0 % and between nurse and expert it was 78.3 % (difference between the means 2.7 %, 95 % CL - 1.0 %, 6.4 %). There was no difference between doctors and nurses in the rate of biopsy performance (90.4 % and 91.1 %, respectively, P = 0.862). Nurses took longer (8.1 minutes vs. 4.6 minutes, P < 0.001) and used intravenous sedation more often (57.6 %, P = 0.027). Adequacy of view correlated positively with endoscopy duration ( P < 0.001), but diagnostic accuracy correlated inversely with duration ( P < 0.001). Neither adequacy or accuracy correlated significantly with use of intravenous sedation. CONCLUSIONS: In endoscopies performed by nurses, the proportion of adequate examinations was much higher than that found for doctors. In areas with an adequate view, there is no significant difference in accuracy between nurses and doctors. Nurses can provide an accurate general diagnostic upper gastrointestinal endoscopy service as competently as doctors.

Predictors of peptic ulcer rebleeding after scheduled second endoscopy: clinical or endoscopic factors?

BACKGROUND AND STUDY AIMS: In a previous study we demonstrated the efficacy of second-look endoscopy with therapy within 16 - 24 hours after index endoscopy in reducing major recurrent peptic ulcer bleeding. In this study, we sought to identify factors that might predict further rebleeding after this scheduled second-look endoscopy. PATIENTS AND METHODS: We studied 249 patients (181 men, 68 women) with acute bleeding peptic ulcers who were treated at the United Christian Hospital, Hong Kong from 1999 to 2002 and who underwent a scheduled second endoscopy. Those patients who developed rebleeding after the second endoscopy were evaluated, and possible predictive factors for rebleeding were analyzed using a logistic regression model. RESULTS: Of the 249 patients who underwent scheduled second-look endoscopy, 17 patients (6.8 %) developed rebleeding: seven of these patients were treated by another endoscopic therapy; ten patients required surgery. The overall mortality rate was 3.1 %. A logistic regression analysis performed on the possible predictive factors for rebleeding found that the following factors were associated with a significant risk of further rebleeding after scheduled second endoscopy: American Society of Anesthesiologists (ASA) grade III or grade IV status (odds ratio 3.81, 95 % CI 1.27 - 11.44), ulcer size greater than 1.0 cm (odds ratio 4.69, 95 % CI 1.60 - 13.80), and a finding of persistent stigmata of recent hemorrhage at the scheduled second endoscopy (odds ratio 6.65, 95 % CI 2.11 - 20.98). CONCLUSIONS: Endoscopic factors, including large ulcer size and the persistence of endoscopic stigmata of recent hemorrhage are important predictors for recurrent bleeding after scheduled second endoscopy.

Effectiveness of open-access endoscopy in routine primary-care practice.

BACKGROUND: Direct referral of patients for endoscopic procedures without prior consultation (open-access endoscopy) has become commonplace. However, the effect of open-access endoscopy on the care of patients in routine clinical practice has not been studied. METHODS: The impact of open-access endoscopy was examined in 168 consecutive patients referred from 8 primary-care practices to our tertiary hospital-based endoscopy center. The effectiveness of open-access endoscopy was assessed by review of office medical records at the primary-care practice sites for a minimum follow-up period of 6 months. Outcome measures evaluated included postprocedure communication between primary-care physician and patient, primary-care physician adherence to postprocedure recommendations, and the need for subsequent diagnostic evaluation and/or consultation. RESULTS: The mean age of the 168 patients was 60 years; 56 (33%) underwent EGD and 112 (67%) had colonoscopy; 65% were from hospital-based practices and 35% from community practices. The indication(s) for 77% of the procedures met American Society for Gastrointestinal Endoscopy guidelines for the appropriate use of endoscopy. An office follow-up was noted for 82% of patients after the open-access procedure. Discussion of results was documented in 61% of the patient charts. Compliance with diagnostic and therapeutic recommendations was documented, respectively, in 75% and 90% of patient charts. A follow-up GI consultation was requested for only 7% of the patients. CONCLUSION: Open-access endoscopy in the primary-care setting is effective to the extent that subsequent GI consultations are rare and the level of compliance with endoscopist recommendations is high. However, documentation of communication of the results of endoscopy with the patient can be improved.

The effects of a psychological preparation program on anxiety in children and adolescents undergoing gastrointestinal endoscopy.

BACKGROUND: Like adults, children often experience anxiety associated with medical procedures. The purpose of this study was to investigate the effects of a program of psychological preparation for children undergoing endoscopy. METHODS: Sixty patients aged 6 to 19 years (mean, 12.2 years) were randomized into one of two groups. Group 1 received routine preparation before endoscopy. Group 2 received psychological preparation consisting of demonstration of materials that would be encountered during the procedure, use of a doll as a model, or use of a book with photographs of a child who had previously undergone endoscopy. Patients in both groups completed the Spielberger State-Trait Anxiety Inventory in the clinic and just before endoscopy. The Observational Scale of Behavioral Distress was completed by a blinded observer during each procedure. The attending physician (blinded) assessed patient cooperation. Vital signs were recorded in clinic and just before endoscopy. Parents and patients completed questionnaires after endoscopy. RESULTS: Analysis of the Spielberger State-Trait Anxiety Inventory showed patients in group 2 were significantly less anxious before endoscopy (p < 0.0001). They also required less meperidine (p < eq 0.04) per kilogram body weight and were more cooperative during the examination (p = 0.042). There was significantly less autonomic nervous system stimulation in those who had undergone psychological preparation (change in heart rate, p < 0.001; change in systolic blood pressure, p = 0.04). Statistically significant differences were found in the patients' response to questions after endoscopy regarding perceived anxiety during the procedure (p = 0.003) and the parents' response to questions regarding their own conditions (p = 0.026) and that of their child (p < 0.001). CONCLUSION: Psychological preparation before endoscopy significantly decreases patient and parental anxiety. Such preparation may allow for a reduction in sedative medications and thereby enhance procedural safety.

Cost minimization in endoscopy center scheduling: a case-controlled study.

BACKGROUND: Traditional endoscopy center scheduling often results in nonurgent inpatient endoscopic procedures being delayed until late in the day and can prolong length of hospital stay and costs. We report the first controlled study designed to evaluate the effect of an early morning fast-track triage endoscopy unit on the cost and length of stay of a general GI inpatient population. METHODS: A case-control methodology matched a cohort of patients undergoing morning triage procedures with historical controls that underwent standard add-on scheduling endoscopy. Outcome indices and patient quality of care measures were compared between cases and controls. RESULTS: Analysis of patients most likely to benefit from rapid endoscopy showed significant advantage comparing fast-track endoscopy patients to controls in time to endoscopy (0.63 vs. 1.00 days, P = 0.01), length of stay (1.22 vs. 1.78 days, P = 0.05), and hospital costs (2,793 dollars vs. 3,586 dollars, P = 0.02). CONCLUSIONS: When routine endoscopy is the rate-limiting step for hospital discharge in the general GI patient, early morning scheduling with a reserved time and space for inpatient endoscopy is a cost-minimizing factor in a busy endoscopy center that may save significant hospital costs while preserving optimal patient outcomes.

Provision of gastrointestinal endoscopy and related services for a district general hospital. Working Party of the Clinical Services Committee of the British Society of Gastroenterology.

(1) The number of endoscopic examinations performed is rising. Epidemiological data and the workload of well developed units show that annual requirements per head of population are approaching: Upper gastrointestinal 1 in 100 Flexible sigmoidoscopy 1 in 500 Colonoscopy 1 in 500 ERCP 1 in 2000 (2) Open access endoscopy to general practitioners is desirable and increasingly sought. For a district general hospital serving a population of 250,000, this workload entails about 3500 procedures annually, performed during 10 half day routine sessions plus emergency work. (3) High standards of training and experience are needed by all staff, who must work in purpose built accommodation designed to promote efficient and safe practice. (4) The endoscopy unit should be adjacent to day care facilities and near the x ray department. There should be easy access to wards. (5) An endoscopy unit needs at least two endoscopy rooms; a fully ventilated cleaning/disinfection area; rooms for patient reception, preparation, and recovery; and accommodation for administration, storage, and staff amenities. (6) The service should be consultant based. At least 10 clinical sessions are required, made up of six or more consultant sessions and two to four clinical assistant, hospital practitioner, or staff specialist sessions. Each consultant should be expected to commit at least two sessions weekly to endoscopy. Extra consultant sessions may be needed to provide an efficient service. (7) A specially trained nursing sister (grade G or H) and five other endoscopy nurses are needed to care for the patients; their work may be supplemented by care assistants. (8) A new post of endoscopy department assistant (analogous to an operating department assistant) is proposed to maintain and prepare instruments, and to give technical assistance during procedures. (9) A full time secretary should be employed. Records, appointments, and audit should be computer based. (10) ERCP needs the collaboration of an interventional radiologist working with high quality x ray equipment in a specially prepared radiology screening room. This facility may need to serve more than one hospital. (11) A gastrointestinal measurement laboratory can conveniently be combined with the endoscopy unit. In some hospitals one or more gastrointestinal measurement technicians may staff this laboratory. (12) An endoscopy unit is a service department analogous to a radiology department. It needs an annual budget.

Improving the selection of patients for upper gastrointestinal endoscopy.

A retrospective study was undertaken to investigate how endoscopies yielding positive findings differ a priori from those yielding negative findings: and how those judged 'helpful' (in the sense of influencing management) differ a priori from those judged 'unhelpful'. A total of 483 patients undergoing endoscopy was sampled and a wide range of data abstracted, including 48 patient characteristics available to the gastroenterologist at the time of the decision to perform endoscopy. Sixty nine per cent of endoscopies were positive. Multivariate statistical analysis identified four variables which taken together were strongly predictive of a positive endoscopy. The resulting mathematical formula correctly predicted the outcome of 76% of endoscopies. Eighty two per cent of the endoscopies were retrospectively classified by the gastroenterologists as helpful. Six variables were strongly predictive of a helpful endoscopy. The corresponding formula correctly predicted the finding of 84% of endoscopies. Comparison of the two analyses shows that the two sets of predictions differ substantially. Thus it is important that decision tools should be based not on the crude distinction between positive and negative, but on the more useful distinction between helpful and unhelpful in influencing management.
