[Clinical application of transesophageal intraluminal ultrasonography to the esophageal carcinoma].

OBJECTIVE: To study the value of transesophageal echo probe (TEEP) in preoperative staging of esophageal carcinoma. METHOD: Between September 1996 and August 1997, 32 patients (22 men and 10 women) with esophageal carcinoma, aged 49 to 72 years (mean age, 55.2 years), underwent surgery. Preoperative examinations included upper gastrointestinal series, endoscopy, and TEEP. Seven of these patients also received CT scan. Resected specimens of the esophagus and lymph nodes were examined histopathologically, and the results of TEEP and CT were compared with intraoperative macroscopic findings and pathologic results. RESULT: The tumor length measured by gastroscopy, TEEP and pathology was 4.524 +/- 1.806 cm, 5.269 +/- 1.916 cm, and 5.345 +/- 1.901 cm, respectively. There was a significant difference between the results of gastroscopy and those of pathology (P < 0.05), but no significant difference was seen between the results of TEEP and those of pathology (P > 0.05). The accuracy of TEEP for predicting T and N staging was 80.6% (25/31) and 77.3% (34/44), respectively. The accuracy of CT for predicting T staging was only 42.9%. CONCLUSION: TEEP is a reliable method for the preoperative TN-staging of esophageal carcinoma and it is more accurate than CT. TEEP is more accurate than gastroscopy in measuring the length of esophageal cancer. In our experience, the procedure is safe without any complications.

[Preoperative esophagogastroduodenoscopy before elective surgical therapy of symptomatic cholelithiasis].

We evaluated the data of 1143 patients who underwent preoperative gastroscopy or upper gastrointestinal series before elective surgical treatment of cholelithiasis between January 1, 1981 and December 31, 1990. On these 824 women and 319 men we performed 1064 (93.1%) gastroscopies and only 78 (6.8%) upper gastrointestinal series. The incidence of pathological findings was 30.2% (345 patients), with 68.3% findings of inflammatory nature. In 28 patients (2.5%) cholecystectomy or bile duct exploration was combined with an additional gastrointestinal surgical procedure. In 227 cases (19.8%) biliary surgery was followed by pharmacological treatment of the gastrointestinal disease. Because of the high incidence of simultaneous disease of the upper gastrointestinum we believe that routine preoperative gastroscopy is indicated before elective surgical treatment of cholelithiasis.

[Surgical treatment of massive rebleeding after gastrectomy for bleeding gastroduodenal ulcer].

OBJECTIVE: To summarize the reoperation experiences in treatment of massive rebleeding after subtotal gastrectomy for bleeding gastroduodenal ulcer. METHODS: From 1980 to 2002, clinical data of 26 cases with massive rebleeding after subtotal gastrectomy for bleeding gastrorenal ulcer were analyzed retrospectively. RESULTS: Preoperative gastroscopy was performed in 6 cases, intraoperative gastroscopy in 11, and preoperative superselective angiography in 2 cases. Eleven cases with left ulcer or post- bulb ulcer bleeding underwent resection of the left ulcer or longitudinal incision of the duodenal descending part and direct hemostasis. Thirteen cases with anastomotic stoma bleeding underwent local suture hemostasis or resection of the stoma plus Billroth II or Roux- en- Y gastrojejunostomy. Two cases with gastric bleeding received reexcision of the stomach remnant. Twenty- four cases (92.3% ) were cured and 2 cases (7.7% ) died of gastric bleeding. CONCLUSION: Preoperative superselective angiography and intraoperative gastroscopy are beneficial to clarify the bleeding position and causes for massive rebleeding after gastrectomy. It is very important to select proper operative method to prevent postoperative rebleeding.

[Clinical significance of serological markers of Helicobacter pylori].

Helicobacter pylori (H. pylori) is a Gram-negative, curved bacillus known since 1983. It is supposed to play role in the pathogenesis of certain gastroduodenic diseases, e.g. non-ulcer dyspepsia (NUD), chronic inflammation, ulcers, etc. Serum samples of 70 patients who were examined for stomach complaints with gastroscopy and those of 22 healthy persons were analysed. The purpose of the study was to evaluate anti-H. pylori IgG, IgM and IgA antibodies using ELISA method. Whether the antibodies can be detected or not, 8 possible variations exist, each of them denoting certain state of infection. These states are not always going parallel with the macroscopic pictures revealed by gastroscopy, but there are some obvious congruences. Results show that serologic examination cannot replace gastroscopy but on the other hand in follow-up tests and examinations as well as in understanding the aetiology of different gastroduodenal diseases it can play an important role.

[Gastrointestinal diseases--the place of endoscopy in examination, treatment and control].

Dyspepsia, defined as discomfort in the upper abdomen after a meal, is the most frequent indication for gastroscopy. Such dyspepsia was earlier considered to be an element of the ulcer disease, Moynihan's disease. Whether examination showed an ulcer or not was of minor importance as long as the treatment was the same. Similar opinions still contribute to a negative attitude towards the need to obtain a more specific diagnosis, especially in young patients where risk of cancer is low. We are of the opinion that dyspepsia is a non-specific symptom of several different diseases, and that curative therapy is often available today provided the diagnosis is correct. It is therefore necessary to make an active effort to diagnose the cause of the dyspepsia, also in younger persons. In practice, this means that there are many different indications for gastroscopy. We try, however, to practice a restrictive policy with respect to control gastroscopy.

Diagnosis of gastrointestinal graft-versus-host disease--is rectal biopsy enough?

BACKGROUND: Graft-versus-host disease (GVHD) is an important cause of morbidity and mortality after allogeneic bone marrow transplantation (BMT). The clinical diagnosis of gastrointestinal GVHD can be difficult to establish and endoscopic diagnosis entails a procedural risk. The aim of this study was to determine whether rectal biopsy alone might be sufficient to establish or exclude the diagnosis of intestinal GVHD. METHODS: A retrospective chart review of children with histological evidence of gastrointestinal GVHD after allogeneic BMT at the Royal Children's Hospital in Melbourne, Australia, between January 1981 and July 2004. RESULTS: During the study period, 264 patients received allogeneic BMT. Thirty-three had either an upper or lower gastrointestinal endoscopy, or both. Of these, 14 (8 M: 6 F, mean age 9 years 5 months at the time of BMT) had histological features suggestive of GVHD in at least one gastrointestinal biopsy. Overall, 9 of 14 could have been diagnosed with GVHD on the basis of rectal biopsies alone (negative predictive value: 64%). Gastroscopy was needed to establish the diagnosis in a further five patients. Multiple biopsies obtained from each site in the lower gastrointestinal tract showed similar histological findings, but there was frequent non-agreement between biopsies obtained at differing sites within the upper gastrointestinal tract. CONCLUSIONS: Based on these results, we suggest that regardless of symptoms, rectal biopsy should initially be performed to identify gastrointestinal GVHD. Gastroscopy should be added only if the rectal biopsy is unhelpful and there is still good reason to suspect GVHD.

Endoscopy in patients undergoing gastroplasty for morbid obesity.

Fifty patients underwent gastroplasty for morbid obesity. The follow-up regimen included both nutritional and weight assessment and gastroscopy. Weight loss was satisfactory in patients with gastric stomas less than 9 mm in diameter. Stomal obstruction was endoscopically diagnosed in 5 patients. Endoscopic dilatation was successful in 4 patients. Gastroscopy should thus be a routine postoperative procedure in patients undergoing gastric partitioning for morbid obesity.

Helicobacter pylori infection is the major risk factor for gastric inflammation in the cardia.

We attempted to clarify the pathogenesis of gastric inflammation in the cardia. Eighty Japanese participated in this study. Biopsy specimens of the gastric antrum, corpus, and cardia (1 cm from the squamocolumnar junction) were obtained, and histological gastritis was evaluated. Cardiac inflammation was also evaluated using magnifying gastroscopy. We examined Helicobacter pylori infection, gastric juice pH/bile acid (BA), serum pepsinogen and gastrin levels, gastroesophageal reflux disease (GERD), and habitual smoking and assessed the relations between these factors and cardiac inflammation. The prevalence of H. pylori infection was statistically higher in patients with cardiac inflammation than in those without inflammation (P < 0.05). The relationship was also demonstrated by magnifying gastroscopy. Cardiac inflammation was linked to low acid output but not linked to the BA concentration or habitual smoking. Cardiac inflammation was more pronounced in patients without GERD. These results suggest that H. pylori is a major risk factor for cardiac inflammation in the Japanese.

Late precancerous changes and carcinoma of the gastric stump after Billroth I resection.

Carcinoma of the gastric remnant after resection for benign ulcers is regarded as a rare complication after Billroth I resection. In seventy-four patients reexamined by gastroscopy and multiple biopsies ten to twenty-two years after gastric resection four cases of cancer of the gastric stump were diagnosed and the patients operated on. Another eight patients had regenerative polyps and one patient had a tubular adenoma. The histologic findings in gastroscopic biopsy specimens from the gastric stoma and fundus are compared. Possible precancerous changes and etiologic aspects are discussed briefly. Repeated gastroscopy is recommended starting about ten years after gastric resection for benign ulcers.

Substrate-level energy dependence of acid secretion in the isolated human gastric mucosa.

The substrate-level energy dependence of acid secretion was investigated in the human gastric mucosa in vitro using biopsy specimens obtained during fiberoptic gastroscopy in symptomatic patients. The oxygen consumption and the accumulation of aminopyrine were used as indexes of secretory activity. Basal and histamine-stimulated oxygen uptake by fundic biopsy specimens were not affected by medications (pethidine and diazepam) administered during gastroscopy. Under substrate-depleted conditions, the oxygen consumption and the aminopyrine accumulation of fundic mucosa were not significantly increased by histamine. Stimulation of functional activities by gastric secretagogues was observed only in the presence of exogenous substrates. The ability of various substrates to support acid formation in the presence of gastric secretagogues was evaluated. Carbohydrates were found to be effective substrates in supporting the functional responses of the tissue, with glucose being the most effective. Propionate, butyrate, beta-hydroxybutyrate, and octanoate were ineffective as substrates. Glucose by itself, but not butyrate, significantly increased oxygen uptake and aminopyrine accumulation. The results suggest that the human gastric mucosa, in vitro, has an absolute requirement for metabolic substrates to support secretory responses and that carbohydrates seem to be the preferential substrates.

Visuospatial skills and computer game experience influence the performance of virtual endoscopy.

Advanced medical simulators have been introduced to facilitate surgical and endoscopic training and thereby improve patient safety. Residents trained in the Procedicus Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) laparoscopic simulator perform laparoscopic cholecystectomy safer and faster than a control group. Little has been reported regarding whether factors like gender, computer experience, and visuospatial tests can predict the performance with a medical simulator. Our aim was to investigate whether such factors influence the performance of simulated gastroscopy. Seventeen medical students were asked about computer gaming experiences. Before virtual endoscopy, they performed the visuospatial test PicCOr, which discriminates the ability of the tested person to create a three-dimensional image from a two-dimensional presentation. Each student performed one gastroscopy (level 1, case 1) in the GI Mentor II, Simbionix, and several variables related to performance were registered. Percentage of time spent with a clear view in the endoscope correlated well with the performance on the PicSOr test (r = 0.56, P < 0.001). Efficiency of screening also correlated with PicSOr (r = 0.23, P < 0.05). In students with computer gaming experience, the efficiency of screening increased (33.6% +/- 3.1% versus 22.6% +/- 2.8%, P < 0.05) and the duration of the examination decreased by 1.5 minutes (P < 0.05). A similar trend was seen in men compared with women. The visuospatial test PicSOr predicts the results with the endoscopic simulator GI Mentor II. Two-dimensional image experience, as in computer games, also seems to affect the outcome.

Trends in the prevalence of Helicobacter pylori in symptomatic children in the era of eradication.

PURPOSE: Helicobacter pylori infection is common in Asia and is associated with dyspepsia, peptic ulcer, and gastric cancer. Eradication of the organism remains an important goal. Here, we looked at the trends in the prevalence of H pylori in symptomatic children over an 8-year period to assess the impact of an aggressive eradication program. METHOD: A retrospective review was carried out between 1997 and 2004. All children with a history of dyspepsia or acute gastrointestinal bleeding were included and underwent gastroscopy. Three antral biopsies were taken during endoscopy and sent for histological analysis. Positivity of H pylori was treated aggressively with quadruple therapy under protocol. The demographic data, the histological findings, and the H pylori status were recorded. RESULTS: There were a total of 159 patients (71 males, 88 females) who underwent gastroscopy in this period. One hundred nineteen patients showed histological evidence of gastritis, and the positive rate of H pylori was 25.6%. The overall prevalence has not decreased (33.3% in 1997, 27.7% in 2004). Increasing age, however, was associated significantly with the higher risk of H pylori infection. CONCLUSION: H pylori has a high prevalence in Chinese children with increasing age. Eradication efforts seem to be unsuccessful in the reduction of prevalence. We hypothesize that this may be owing to cross-infection at meal times from sharing chopsticks.

[Videocapsule endoscopy as a useful tool to diagnose primary intestinal lymphangiectasia].

INTRODUCTION: Primary intestinal lymphangiectasia (Waldmann's disease) lead to a protein-losing enteropathy due to lymph leak into intestinal tract. EXEGESIS: A 28-year-old woman presented a bilateral lower limb lymphedema. Laboratory examination showing lymphopenia, hypoalbuminemia, hypogammaglobulinemia suggested the diagnosis of primary intestinal lymphangiectasia. Gastroscopy was normal and second duodenum biopsies were negative. Videocapsule endoscopy gave evidence of intestinal lymphangiectasia of the small bowel. CONCLUSION: Videocapsule endoscopy may be proposed to confirm intestinal lymphangiectasia and to precise their localization when gastroscopy is not conclusive.

Retrosternal pain subsequent to sclerotherapy.

A controlled trial was conducted to determine the etiology of retrosternal pain following sclerotherapy. Sclerotherapy was performed on patients that had previously bled from varices. Esophageal motility studies were recorded from seven patients prior to sclerotherapy and immediately subsequent (within 10 min) to it. Motility studies were also recorded from seven normal subjects before and after undergoing gastroscopy to determine the effects of gastroscopy upon esophageal motility. Sclerotherapy appears to induce a transient pattern of diffuse esophageal spasm, the main features of which are significantly (p less than 0.05) prolonged wave duration, increased peak amplitude, and simultaneous contractions.

Hemorrhagic gastropathy in epidemic nephropathy.

A patient with epidemic nephropathy (NE) and with gastrointestinal symptoms and hemorrhagic gastropathy prompted us to study further 10 consecutive patients with NE. Gastroscopy was carried out within 1 to 4 weeks after the beginning of the symptoms, and in every case a hemorrhagic gastropathy was observed. Hemorrhagic lesions were more marked, the shorter the elapsed time interval from the beginning of symptoms. Hemorrhagic changes were always more prominent in the proximal than in the distal part of the stomach. In 7 of 10 patients lesions were also observed in the duodenum. Colonoscopy was done in one patient and it showed similar spotty hemorrhages, suggesting that hemorrhagic lesions were not limited to the gastroduodenal mucosa only. Histological studies disclosed that the hemorrhagic lesions were associated with edema in the lamina propria, but without inflammatory changes. Follow-up gastroscopy in three patients 3 to 8 weeks later showed disappearance of hemorrhagic lesions in every patient. Thus, these results show for the first time that hemorrhagic gastropathy is a common finding in NE, and it may explain the abdominal symptoms and gastrointestinal bleeding in some of these patients. However, the mechanism of the hemorrhagic lesions needs further exploration.

Endoscopy is not a risk factor for Helicobacter pylori infection--but medical practice is.

BACKGROUND: Previous studies have suggested an increased risk for Helicobacter pylori infection in physicians who perform UGI endoscopy because of exposure to potentially infectious gastric secretions. Therefore, the H. pylori infection status of the endoscopy staff was compared with the H. pylori prevalence of medical staff without endoscopy experience and control subjects who had no contact with patients. METHODS: The noninvasive 13C-urea breath test was performed in 2108 volunteers: 1460 physicians (mean age 44 +/- 12 years), 235 nurses (33 +/- 10 years), and 413 control subjects (43 +/- 12 years) who were not working in clinical medicine. All subjects completed a questionnaire concerning the weekly frequency of gastroscopies and the duration of endoscopic experience. RESULTS: Overall, 37.4% of the physicians and 35.3% of the nurses, but only 27.1% of the control subjects were infected. H. pylori infection was not significantly different between endoscopy-performing (37.8%; n = 1091) and general medical staff (35.9%; n = 604). Neither the frequency of gastroscopies nor the duration of endoscopy practice correlated with H. pylori status. With respect to the age distribution; however, a statistically significant higher prevalence of H. pylori was observed in physicians and nurses compared with the 413 control subjects without patient contact (p < 0.01). CONCLUSION: UGI endoscopy is not a risk factor for H. pylori infection, but medical practice slightly raises H. pylori acquisition.

Gastroallergic anisakiasis: borderline between food allergy and parasitic disease-clinical and allergologic evaluation of 20 patients with confirmed acute parasitism by Anisakis simplex.

BACKGROUND: Human subjects can be parasitized by Anisakis simplex by eating raw or undercooked fish. Gastric anisakiasis is probably the most frequent clinical entity presenting with severe epigastric pain, vomiting, and diarrhea. In gastroallergic anisakiasis hypersensitivity symptoms predominate. OBJECTIVE: We sought to describe clinical features, laboratory data, and gastroscopic findings in gastroallergic anisakiasis. METHODS: We selected 40 patients presenting to the emergency department with an acute allergic reaction, and if we suspected acute parasitism by A simplex, a fiberoptic gastroscopy was performed. In 20 patients we could detect one or more nematodes; these patients are referred to as group A. Those in whom no worm could be found are referred to as group B (n = 20). A detailed history, clinical features, gastroscopic findings, laboratory data, and skin prick test responses were compared. RESULTS: Long-time intervals of up to 26 hours between fish intake and onset of hypersensitivity symptoms were found (group A, 5.4 +/- 6.3 hours; group B, 5.3 +/- 2.6 hours). Patients in groups A and B did not differ with respect to allergic symptoms (urticaria, angioedema, erythema, bronchospasm, and anaphylaxis) or the mainly light abdominal symptoms (upper abdominal pain, nausea, vomiting, and diarrhea). No significant differences were found with respect to age, time interval between fish intake and onset of symptoms, white cell and eosinophil counts, specific IgE levels against A simplex, or total IgE levels. CONCLUSIONS: The peculiar sometimes long-time interval between fish intake and onset of allergic symptoms render the diagnosis difficult. An early gastroscopy can confirm the diagnosis and prevent complications. We suggest that gastroallergic anisakiasis be considered a distinct clinical entity in which the predominant symptoms are hypersensitivity symptoms and in which the correct diagnosis is not only important in the management of the acute reaction but also in the prevention of further allergic episodes.

Upper gastrointestinal endoscopy in patients aged 85 years or more. Results of a feasibility study in a district general hospital.

We performed a cross sectional analysis of the feasibility and yield of upper gastrointestinal endoscopy (UGE) in a cohort of patients aged 85 years or more. The study involved 218 patients who underwent diagnostic upper gastrointestinal endoscopy in a district general hospital between 1994 and 1998. Indication, use of sedation, endoscopic findings and treatment after endoscopy were evaluated. Indications for gastroscopy were suspicious of upper gastrointestinal bleeding (UGI) bleeding (41%), anemia (15%), and presence of dyspeptic- (31%), alarm- (9%) and/or reflux symptoms (3%). Serious UGI disease (cancer, peptic ulcer, reflux oesofagitis and/or erosive gastritis/duodenitis) was detected in 97 patients (44%). With respect to clinical presentation, serious UGI disease was present in 61% with bleeding, in 57% with reflux symptoms, in 42% with alarm symptoms, in 33% with anemia and in 28% with dyspepsia. Carcinoma was detected in eight patients (3.8%), all of them were treated with supportive care. In very old people gastroscopy is generally performed on sound indications reveals serious UGI disease in almost one out of two patients, markedly influences medical treatment, and reveals low malignancy rates (3.8%). In these patients, UGE is worthwhile and should not be omitted because of age considerations.
