Prospective assessment of the risk of bacteremia in cirrhotic patients undergoing lower intestinal endoscopy.

BACKGROUND: Patients who have prosthetic heart valves, previous history of endocarditis, and surgically constructed systemic-pulmonary shunts or conduits should receive prophylactic antibiotics before colonoscopy. The usefulness of this approach in cirrhotic patients remains unknown. The present study prospectively assesses the incidence of bacteremia in these patients. METHODS: Lower intestinal endoscopy was performed in 58 cirrhotic patients. Two blood samples were obtained from every patient (just before endoscopy and within 5 minutes of withdrawal of the endoscope) and were incubated for 7 days and examined daily for growth of bacteria. Patients were closely monitored for 72 hours after endoscopy to detect the development of infectious complications. RESULTS: Only 6 cultures from 6 patients were positive. Four were obtained post-endoscopy and the remaining 2 before colonoscopy but the corresponding post-endoscopy samples were negative. All organisms recovered were normal skin flora. All patients, including those with positive cultures, remained asymptomatic during the 72 hours after the procedure. CONCLUSIONS: Our findings indicate that lower intestinal endoscopy does not induce bacteremia in cirrhotic patients with or without ascites in the absence of gastrointestinal bleeding and do not support the routine use of prophylactic antibiotics in these patients.

A system of credentialing physicians in advanced gynecologic endoscopy.

STUDY OBJECTIVE: To develop criteria for credentialing physicians in advanced gynecologic endoscopy. DESIGN: Descriptive study (Canadian Task Force classification III). SETTING: University-affiliated community hospital. Patients. None. INTERVENTION: Criteria for credentialing physicians were tested. MEASUREMENTS AND MAIN RESULTS: Physicians were granted universal privileges in advanced gynecologic laparoscopy or hysteroscopy when they were certified by the Accreditation Council for Gynecologic Endoscopy (ACGE). Alternatively, they received category-specific privileges in any one of six categories when they provided documentation of having satisfactorily performed 10 cases in four categories or 5 cases in the remaining two. Required cases included those performed during residency or with a proctor. Completion of an approved residency, board certification or eligibility, and good standing were other requirements. Proof of continuing medical education in endoscopy was also considered. Of 31 physicians in the department, 3 had ACGE certification: 1 in laparoscopy, 2 in laparoscopy and hysteroscopy. Three physicians gained privileges under the alternative system. One received category 1, one received categories 1 and 2, and the third received categories 1, 2, and 6 privileges. Twenty-five physicians were granted standard endoscopy privileges, including six who applied for advanced endoscopy privileges. These applications are pending case documentation and proctorship. CONCLUSION: A system for credentialing physicians in advanced gynecologic endoscopy, using two alternative pathways, was implemented.

The laryngeal mask airway as an aid to training in fibreoptic nasotracheal endoscopy.

We have investigated the extent to which the laryngeal mask airway, when used as an aid to fibreoptic nasotracheal video-endoscopy training, could reduce endoscopy apnoeic time in anaesthetised, paralysed oral surgery patients. Twenty anaesthetic trainees were randomly allocated to the laryngeal mask airway or control group. Laryngeal mask airway group endoscopies were performed in three stages following insertion of the laryngeal mask airway; stage 1: nasendoscopy, with the lungs ventilated automatically through the laryngeal mask airway; stage 2: removal of the laryngeal mask airway; stage 3: pharyngoscopy, larygoscopy and tracheoscopy. Control group endoscopies were performed conventionally, in one stage. Each trainee performed five nasotracheal intubations. Though total endoscopy time in the laryngeal mask airway group (stage 1 + stage 2 + stage 3 times) was significantly longer (average 136 s vs. 108 s), apnoeic time (stage 2 + stage 3 times) was significantly shorter (average 59 s vs. 108 s) than endoscopy time in the control group. This application of the laryngeal mask airway may have a useful role to play in ensuring patient safety during early fibreoptic training.

Newly developing hiatus hernia: a survey in patients undergoing upper gastrointestinal endoscopy.

BACKGROUND: Data on the incidence of hiatus hernia are lacking. A cross-sectional study was performed in a large population of consecutive patients undergoing endoscopy in order to assess the yearly incidence of hiatus hernia in this population. METHODS: Consecutive patients undergoing upper gastrointestinal endoscopy in whom no macroscopic abnormalities were seen and who, in addition, underwent a second endoscopy were included in the study. The presence of newly developed hiatus hernia was noted, as well as the time elapsed between both endoscopies. RESULTS: Over a period of 8 years, 12 122 endoscopies were performed in 9580 patients. Ninety patients developed a hiatus hernia; this was not the case in a control group of 353 patients. Patients who developed a hiatus hernia were significantly older than those who did not (P < 0.001). The number of women who developed hiatus hernia was higher than the number of men who developed hiatus hernia (P < 0.0001). The total time between both endoscopies in 443 patients was 897 patient years. Ninety patients (20.3%) developed a hiatus hernia. If these data are extrapolated to a yearly occurrence, then 35 of 176 patients will develop a hiatus hernia. It takes an average of 1.9 years for a hiatus hernia to develop. CONCLUSIONS: In the present study, it was calculated that 19.9% of the studied population would develop a hiatus hernia per year. Patients who developed a hiatus hernia were significantly older than patients who did not. The present study also shows that a hiatus hernia actually develops later in life.

Value of chromoendoscopy and magnification endoscopy in the evaluation of duodenal abnormalities: a prospective, randomized comparison.

BACKGROUND AND STUDY AIMS: Endoscopic staining methods are increasingly being used to evaluate lesions in the esophagus and colon. The aim of this prospective study was to investigate chromoendoscopy and magnification endoscopy for the evaluation of mucosal lesions in the duodenum. PATIENTS AND METHODS: Consecutive patients were randomly assigned to undergo conventional endoscopy without staining (group A) or intravital staining of the duodenal mucosa with indigo carmine and evaluation with a conventional video endoscope (group B) or a magnification endoscope (group C). Visible lesions were characterized before and after staining, and biopsies were taken for histological assessment. RESULTS: A total of 118 patients was examined. Chromoendoscopy detected significantly more lesions in the duodenal bulb (98 vs. 28; P = 0.0042) in more patients (29 vs. 15; P = 0.0025) compared with conventional endoscopy (group A). After mucosal staining, there was no difference between video endoscopy and magnification endoscopy with regard to the number or extent of the lesions identified. Significantly more targeted biopsies were possible after intravital staining. The most commonly identified lesions on targeted biopsies included (staining/control groups): gastric metaplasia (14/3), hyperplastic Brunner's glands (6/3), inflammatory changes (7/6), villous atrophy (1/3), adenoma (1/0). CONCLUSIONS: Intravital staining of the duodenum with indigo carmine may be useful for detecting mucosal abnormalities, delineating their extent, and allowing targeted biopsies. Magnification endoscopy, when used in addition to chromoendoscopy, does not appear to further increase the diagnostic yield for detecting duodenal abnormalities.

Nonattendance at outpatient endoscopy.

BACKGROUND AND STUDY AIMS: Nonattendance at outpatient endoscopy leads to inefficiency and delay in diagnosis. We aimed to identify factors associated with failure to attend outpatient gastroscopy and colonoscopy. PATIENTS AND METHODS: We carried out a retrospective audit of nonattendance at outpatient endoscopy over a 12-month period at our tertiary hospital endoscopy unit. Attending patients on the same endoscopy list were used as controls. Patient charts and referral letters were reviewed. The information collected included referral source, time between referral and procedure, indication and type of procedure, reason for nonattendance and history of previous endoscopy. Following the audit a trial of telephone reminders was implemented over a 3-month period. RESULTS: From 2157 outpatient procedures that were scheduled, 263 nonattendees (12.2 %) were identified with 261 controls. Of the nonattendees, 109 (41 %) did not attend for colonoscopy, 121 (46 %) did not attend for gastroscopy and 33 (13 %) failed to turn up for combined procedures. Monday was the most common day of the week for nonattendance (40 % of nonattenders). Nonattendees were younger (46 +/- 14 vs. 55 +/- 16, P < 0.001), less likely to be referred from a gastroenterologist ( P < 0.001) or private practice ( P = 0.02) and more likely to be referred from the emergency department ( P = 0.007). Subsequent to this, a 3-month period of telephone reminder reduced nonattendance rates from 12.2 % to 9 % ( P = 0.03). CONCLUSIONS: Younger patients scheduled for outpatient endoscopy on Mondays who are not referred by a gastroenterologist or private physician are more likely not to attend. These patients should be targeted for interventions designed to increase attendance. Telephone reminders have a modest effect on reducing nonattendance rates.

Impact of open-access endoscopy on detection of early oesophageal and gastric cancer 1994 - 2003: population-based study.

BACKGROUND AND STUDY AIMS: There is conflicting evidence regarding the ability of open-access endoscopy to detect oesophageal and gastric cancers at an earlier stage. The aim of the study was to assess the impact, with regard to earlier diagnosis of oesophageal and gastric cancer, of the first 10 years of a regional open-access endoscopy service in the Dumfries and Galloway region of Scotland. PATIENTS AND METHODS: Data were retrieved from prospectively compiled endoscopy and cancer registry databases. Route of referral (open-access vs. outpatient vs. inpatient), presenting symptoms (alarm vs. benign) and UICC disease stage in consecutive 5-year periods (1994 - 1998 and 1999 - 2003) were compared. RESULTS: 386 oesophagogastric cancers were identified (179 during 1994 - 1998 and 207 in 1999 - 2003). The number of patients undergoing endoscopy increased from 500 per annum prior to the open-access service to 7359 during 1994 - 1998 and 9701 in 1999 - 2003. Patient age, route of referral and presenting symptoms were unchanged. There was no improvement in disease stage at diagnosis (stage I, 7 % vs. 7 %; stage II, 16 % vs. 17 %; stage III, 31 % vs. 28 %). CONCLUSIONS: Despite a 32 % increase in endoscopy workload, the provision, over 10 years, of a regional open-access endoscopy service was not associated with earlier detection of oesophageal or gastric cancer.

Oral sedation for diagnostic upper endoscopy.

Heavy i.v. sedation is often used in upper GI endoscopy. Sedation, however, creates the need for recovery facilities and precludes patients from returning to their normal daily activities. This is undesirable, since endoscopy is routinely performed as an out-patient procedure. Also the cost for medication and recovery facilities militate against the indiscriminate use of i.v. sedative premedication. The present study was undertaken in an attempt to establish what proportion of patients can benefit from oral premedication, and whether such an administration route can eliminate some of the disadvantages associated with i.v. sedation. Four hundred out-patients were randomized to receive orally either triazolam, 0.125 mg, or placebo. Of the patients, 359 were evaluable; 177 received placebo and 182 triazolam. All major aspects of the procedure were covered using visual analogue scale questionnaires for the endoscopist and patient. There were no differences in endoscopic experience, or sex and age distribution between the groups. Triazolam reduced patient discomfort, 38.6 +/- 25.6 vs 44.8 +/- 30.1 (p = 0.0379). Recollection of post-endoscopy information was the same in both groups. One patient complained of drowsiness following the procedure. No patient needed to stay in hospital to complete recovery. Endoscopy quality was identical in the two groups. Oral premedication has the potential to be of significant value, may optimize the use of endoscopy resources, and does not impair patient activities post-endoscopy.

Low yield of endoscopy in patients with persistent dyspepsia taking proton pump inhibitors.

BACKGROUND: Options for the evaluation of dyspepsia include a Helicobacter pylori test-and-treat strategy, empiric acid suppression, and initial endoscopy. The aim of this study was to determine the yield of endoscopy in patients in whom empiric therapy is unsuccessful compared with patients who received no empiric therapy and to identify factors associated with endoscopic findings. METHODS: A total of 100 patients with dyspepsia referred for endoscopy completed a questionnaire that included a query concerning response to therapy. EGD findings were compared in patients taking an H2-receptor antagonist, patients taking a proton pump inhibitor, and those not receiving empiric therapy. RESULTS: There were fewer endoscopic findings in patients being treated with a proton pump inhibitor compared with those taking an H2-receptor antagonist or those not receiving therapy (p < 0.01). Fewer proton pump inhibitor recipients had esophagitis or ulcer compared with patients in the no therapy group. Lack of symptom relief (<20%) by acid suppression was highly associated with a normal endoscopy (17/17). CONCLUSIONS: Patients with persistent dyspepsia being treated with a proton pump inhibitor have fewer endoscopic abnormalities compared with patients with dyspepsia taking an H2-receptor antagonist and those receiving no therapy. For patients with partial symptom relief, proton pump inhibitor therapy may mask endoscopic findings, particularly esophagitis. Interruption of proton pump inhibitors before endoscopy may increase diagnostic yield. Endoscopy is unlikely to yield a positive finding in patients who experience no symptom relief while taking a proton pump inhibitor or H2-receptor antagonist.

Evaluation of airway obstruction using virtual endoscopy.

OBJECTIVES: This study examines the use of virtual endoscopy (VE) in the evaluation of patients with upper airway obstruction. The utility of VE compared with actual endoscopy was investigated with respect to accuracy of diagnosis and reproduction of endoscopic images. STUDY DESIGN: A random cohort of 30 patients with various causes of airway obstruction was examined. METHODS: The computed tomography (CT) data were reconstructed using a proprietary VE software program, FreeFlight, blind to the actual endoscopic findings. The cause of obstruction was identified and compared with actual endoscopic findings. This included 21 patients with airway stenoses, 8 patients with laryngotracheomalacia, 3 tracheal tumors, 2 glottic webs, 5 patients with innominate artery compression, 2 tracheal granulomas, and 7 patients with impaired true vocal cord mobility. RESULTS: Virtual endoscopic evaluation was accurate in assessing stenosis width and length of fixed airway lesions. Correlation of stenosis shape and contour between actual endoscopy and VE was excellent. The stenosis-to-lumen ratios were compared between VE and actual endoscopy and were found to be within 10% (SD = 8). However, virtual endoscopic evaluation could not illustrate one of the glottic webs, half of the cases of tracheomalacia, or any of the cases of impaired true vocal cord mobility. CONCLUSIONS: Virtual endoscopy was not as sensitive as actual endoscopy in detecting the cause of airway obstruction that was based on dynamic movement. However, VE was excellent for the measurement and definition of fixed airway lesions.

Role of flexible endoscopy in the evaluation of possible esophageal trauma after penetrating injuries.

OBJECTIVE: In urban medical centers, penetrating injuries of the chest, neck, and head are frequently encountered due to the use of firearms and sharp weapons. Successful management of esophageal injury requires a high index of suspicion and prompt diagnosis. The role of flexible endoscopy, a readily available modality, has not been studied extensively in the management of potential esophageal injuries due to trauma. METHODS: A retrospective chart review of 55 patients who underwent emergent flexible endoscopy for the evaluation of suspected penetrating esophageal injuries was performed to determine if endoscopy was safe and if it yielded information that altered patient management. RESULTS: Flexible endoscopy was performed safely in all patients. It yielded a sensitivity of 100%, specificity of 92.4%, a negative predictive value of 100%, and a positive predictive value of 33.3% for detecting an esophageal injury. Although positive findings (prevalence, 3.6%) are infrequent, no esophageal injuries were missed. Endoscopy altered patient management in 38 (69.1%) patients. CONCLUSIONS: Emergent flexible endoscopic examination of the esophagus is a safe and useful diagnostic tool in the early evaluation of penetrating injuries. Flexible endoscopy resulted in four negative surgical explorations, which was deemed acceptable by the Trauma Service, as the consequences of a missed esophageal injury is likely to be devastating.

Is endoscopy necessary for the measurement of disease activity in ulcerative colitis?

OBJECTIVES: Many disease activity indices are used to measure ulcerative colitis. Invasive indices incorporate an endoscopic score, while noninvasive indices do not require endoscopy. In clinical practice, many patients are treated based on their symptoms without endoscopic evaluation. However, invasive indices are commonly used in clinical research. Our objective was to determine whether endoscopy is necessary for the assessment of disease activity in patients with ulcerative colitis. METHODS: Sixty-six consecutive ulcerative colitis patients were evaluated with invasive indices: the St. Mark's index and the Ulcerative Colitis Disease Activity Index (UCDAI); and noninvasive indices: the Simple Clinical Colitis Activity Index (SCCAI) and the Seo index. The correlations between the indices were measured. The contribution of the endoscopic items was measured with linear regression modeling. The overlap of endoscopy with other items in the standard indices was determined through factor analysis. RESULTS: The two noninvasive indices correlated well with the invasive St. Mark's Index (SCCAI 0.86, Seo 0.70). After adjusting for the three noninvasive UCDAI items, the UCDAI endoscopy item predicted only 0.04% of the variance in the St. Mark's index. Factor analysis demonstrated that this is because the endoscopy items in the invasive indices correlate with stool frequency and stool blood items. CONCLUSIONS: Endoscopy items contribute little additional information to indices of disease activity in ulcerative colitis. The clinical practice of treating patients based on reported symptoms is appropriate. The use of noninvasive indices in clinical trials could lower study costs and may increase subjects' willingness to participate.

Randomised trial of endoscopy with testing for Helicobacter pylori compared with non-invasive H pylori testing alone in the management of dyspepsia.

OBJECTIVE: To compare the efficacy of non-invasive testing for Helicobacter pylori with that of endoscopy (plus H pylori testing) in the management of patients referred for endoscopic investigation of upper gastrointestinal symptoms. DESIGN: Randomised controlled trial with follow up at 12 months. SETTING: Hospital gastroenterology unit. PARTICIPANTS: 708 patients aged under 55 referred for endoscopic investigation of dyspepsia, randomised to non-invasive breath test for H pylori or endoscopy plus H pylori testing. MAIN OUTCOME MEASURE: Glasgow dyspepsia severity score at one year. Use of medical resources, patient oriented outcomes, and safety were also assessed. RESULTS: In 586 patients followed up at 12 months the mean change in dyspepsia score was 4.8 in the non-invasive H pylori test group and 4.6 in the endoscopy group (95% confidence interval for difference -0.7 to 0.5, P=0.69). Only 8.2% of patients followed up who were randomised to breath test alone were referred for subsequent endoscopy. The use of non-endoscopic resources was similar in the two groups. Reassurance value, concern about missed pathology, overall patient satisfaction, and quality of life were similar in the two groups. The patients found the non-invasive breath test procedure less uncomfortable and distressing than endoscopy with or without sedation. No potentially serious pathology requiring treatment other than eradication of H pylori was missed. CONCLUSION: In this patient group, non-invasive testing for H pylori is as effective and safe as endoscopy and less uncomfortable and distressing for the patient. Non-invasive H pylori testing should be the preferred mode of investigation.

The utility of endoscopic ultrasonography and endoscopy in the endoscopic mucosal resection of early gastric cancer.

OBJECTIVE: To clarify the usefulness of endoscopic ultrasonography (EUS) and endoscopy in the endoscopic mucosal resection (EMR) of early gastric cancer. Patients/Methods-EMR was performed in 61 patients with early gastric cancer over the past five years. The accuracy of the assessment of the depth of cancerous invasion was studied in 49 patients who had EUS before EMR. Forty eight patients were treated with endoscopy alone; in these patients, EUS and endoscopic findings correlated with the clinical course. RESULTS: Forty six patients showed no changes in the submucosal layer or deeper structures on EUS. Pathologically these included 37 patients with mucosal cancer and nine with submucosal cancer showing very slight submucosal infiltration. Three patients showed diffuse low echo changes in the submucosal layer on EUS; pathologically, these included two with submucosal cancer and one with mucosal cancer with a peptic ulcer scar within the tumour focus. Of 48 patients receiving endoscopic treatment alone, 45 showed no tumour recurrence or evidence of metastases on EUS and endoscopy. Three cases of recurrence were observed. Two of these patients had a surgical gastrectomy, and one was re-treated endoscopically. In the former cases, the surgical results correlated well with assessment by EUS and endoscopy. In addition, the latter patient who was re-treated endoscopically after evaluation with EUS and endoscopy has so far had no recurrence. CONCLUSION: The combined use of EUS and endoscopy is effective in diagnosing the depth of cancerous invasion in patients undergoing EMR as well as in clarifying changes both within and between anatomic levels during follow up.

Detection of gastric erosions: comparison of biphasic radiography with fiberoptic endoscopy.

Biphasic radiography was compared with fiberoptic endoscopy in detecting gastric erosions in a prospective, blinded study of 385 patients with dyspepsia. Because no absolute standard was available for the comparison, since histologic confirmation of all erosions was not possible, the kappa statistic was used to compare results from both modalities. Flat (incomplete) erosions were detected with endoscopy only and were considered to be present in 42 patients (11.2%). Varioliform (complete) erosions were identified with both radiography and endoscopy in 12 patients (3.2%). For the detection of varioliform erosions, a substantial agreement beyond chance between both modalities was found (kappa = 0.73; standard error, 0.12). Thus, flat erosions were detected with endoscopy only, whereas state-of-the-art radiography and endoscopy were equally sensitive for detecting varioliform erosions. Histologic confirmation of erosions was obtained in only 75% of the patients. It is unknown whether the demonstration of erosions with radiography and/or endoscopy correlates with dyspepsia.

[Rigid respiratory endoscopy in children].

From march 1989 to march 1992, three hundred and fifty six respiratory endoscopies were performed at "Hospital da Criança Santo Antônio", Porto Alegre, Brazil. The endoscopies were performed with a rigid pediatric bronchoscope and under general anaesthesia. The most common indications for endoscopy were stridor (52%), suspected foreign body (16%), atelectasis (16%) and difficult tracheal extubation (8%). The most frequent diagnosis were laryngomalacia (36%) and subglottic stenosis (6%) in the glottic and subglottic areas, and foreign body (9%) and tracheomalacia (7%) in the tracheobronchial area. Normal endoscopy was observed in 54 (21%) of the children. Only three slight complications of the endoscopy were observed. Two patients presented bradycardia during the exam, and the third needed tracheal intubation due to post-endoscopic subglottic edema. This confirms that the rigid endoscopy in children is efficient and has no serious complications.

[Evaluation of tracheobronchial lesions with spiral CT: comparison between virtual endoscopy and bronchoscopy].

INTRODUCTION: The aim of this study is to describe the scanning parameters for virtual bronchoscopy in the evaluation of the tracheobronchial tree and to compare the results of this examination with the endoscopic findings. MATERIAL AND METHODS: 27 patients with tracheobronchial neoplasms suspected at preliminary clinical and chest film findings or postoperative follow-up for malignant disease were evaluated with spiral CT of the chest and bronchoscopy. Virtual endoscopy was performed on the pulmonary volume involved by the lesion, using narrow axial images (thickness 2 mm, table index 3 mm, reconstruction index 1 mm.) so as to obtain MPR, MIP and 3D reconstructions with 3D Endo Vew program (Philips Medical System, Eindhoven, Holland). We compared these reconstructions and the findings the normal spiral CT scanning with the corresponding endoscopic examinations. RESULTS: In all patients we were able to study the lobar and segmental bronchi in all patients and in 2 we also evaluated the subsegmental bronchi. 25 lesions in 23 patients were shown by virtual endoscopy (8 occlusions, 8 stenosis, 5 compressions, 3 flogosis with endobronchial mucus, 1 bronchocele) and in 4 patients the examinations were negative. The bronchoscopy was negative in 4 patients and positive in 23 patients with 25 lesions, but we had agreement in 23/27 patients (85,1%). In 2 patients virtual endoscopy showed the lesions in a different bronchus compared to bronchoscopy. In one patient we interpreted the obstruction as neoplastic instead of mucus inside the bronchi and in the last patient bronchoscopy was not performed due to his old age and the virtual endoscopy showed total obstruction of a segmental bronchus. DISCUSSION AND CONCLUSIONS: The results show that virtual endoscopy can study the tracheobronchial tree as far as the segmental bronchi, and sometimes also the subsegmental bronchi and the bronchi below a closed obstruction. In addition, it can evaluate the extraluminal location of the lesions. For these reasons virtual endoscopy provides a road map for bronchoscopy as a guide for transbronchial biopsy and for endobronchial treatment planning. The limitation of this technique is its inability to evaluate the mucosal surface and distinguish flogosis from neoplastic lesions by biopsy. It can be used however in the postoperative follow-up both for cancer and transplant, when immediate biopsy is not necessary.

[Assessment of anxiety levels in patients during diagnostic endoscopy].

Patients with increased pre-endoscopic anxiety take advantage of the use of conscious sedation. However, the habit of using premedication varies according to the type of endoscopic examination. Aims of this study were: to evaluate whether different endoscopic procedures may have different effects on patient anxiety; and whether anxiety affects patient tolerance. 163 consecutive outpatients undergoing endoscopy (75 gastroscopy, 51 colonoscopy and 37 bronchoscopy) were interviewed to evaluate pre-endoscopy anxiety, by using the Spielberger State-Trait Anxiety Inventory. After endoscopy, endoscopists rated patient cooperation on a 10-cm visual analogue scale. Females had state and trait anxiety levels higher than males (50.49 +/- 1.37 vs 45.07 +/- 1.20, p < 0.01; and 44.46 +/- 1.06 vs 38.48 +/- 1.01, p < 0.01). Anxiety levels were not related with the type of endoscopic procedure. A direct relationship was observed between state and trait anxiety (p < 0.001). Patient cooperation to endoscopy was inversely related with both trait (p < 0.05) and state anxiety (p < 0.01). In conclusion, gastroscopy, colonoscopy and bronchoscopy seem to induce similar pre-endoscopy anxiety levels. Therefore, the different frequency in the use of intravenous sedation between bronchial and gastrointestinal endoscopy does not seem justified.
