BACKGROUND: The role of Helicobacter pylori in stomach carcinogenesis is currently under study. H pylori-related chronic gastritis leading to dysplasia or intestinal metaplasia (IM) especially of the colonic type is postulated as one of the mechanisms. METHODS: We studied 120 patients with or without H pylori infection to determine the frequency of occurrence of IM in the stomach. RESULTS: IM was found in 16.6% of patients; most cases had the small intestinal type, which is not known to have a malignant potential. There was no relation between H pylori infection and development of IM. CONCLUSION: H pylori infection leading to IM does not appear to be a factor in the genesis of carcinoma stomach in our population.

Prepyloric diaphragms are unusual and are usually detected in adulthood. We report a five-year-old boy who presented with history of ingestion of a coin and was found to have a prepyloric diaphragms on laparotomy.

OBJECTIVE: Results of 20 dilatation sessions in 15 patients with achalasia cardia were assessed to determine the safety and efficacy of polyethylene balloon achalasia dilators (Rigiflex). METHODS: All patients underwent an initial dilatation by inflating a 30 mm balloon to 9 psi for one minute. Need for subsequent dilatations was assessed on symptom assessment; 35 mm balloon was used for repeat procedure. RESULTS: Overall success rate was 93.3%. The 30 mm balloon achieved a satisfactory result in 73.3% and the 35 mm balloon in 75% of the remainder. Only one patient needed surgery. No short-term complications were observed. The only late complication encountered over an average follow-up period of 16.2 months was gastroesophageal reflux in two patients. CONCLUSIONS: Dilatation using Rigiflex dilators is a safe, effective and simple procedure for treating patients with achalasia.

Esophageal tuberculosis is rare and is usually due to secondary extension from contiguous structures. We report a patient who presented with dysphagia and was found to have esophageal stricture. Endoscopic biopsy was not suggestive of malignancy or tuberculosis. CT scan of the thorax revealed involvement of the fourth thoracic vertebra with paratracheal lymphadenopathy. The patient responded to anti-tubercular therapy.

Balloon dilation is an effective modality of treatment for esophageal strictures. As standard through-the-scope balloons do not pass through the biopsy channel of pediatric endoscopes, we have developed a technique by which these balloons can be used in pediatric patients by passing them alongside the endoscope. We report our experience of dilation in four patients using this technique.

OBJECTIVE: To assess the effect of a short course of indomethacin on gastric mucosal blood flow (GMBF). METHODS: Patients with musculo-skeletal pain of recent origin and were prescribed a short course of therapy with indomethacin (25 mg tid for 7 days) were studied Baseline measurements of GMBF were carried out using endoscopic laser-Doppler velocimetry prior to starting indomethacin. At sites on the antrum, incisura, lesser and greater curvatures, and fundus. GMBF measurements were repeated after indomethacin therapy, as above and also on sites of erosions, it any. RESULTS: Baseline GMBF at sites on the antrum, incisura, greater and lesser curvatures, and fundus were (mean) 8.6, 7.9, 8.8, 8.5 and 8.7 volts, respectively. Post-therapy values did not differ from the corresponding baseline values (8.7, 8.5, 8.6, 8.6 and 8.3 volts, respectively). However, ten of the 16 patients developed gastric mucosal erosions and the mean GMBF on these sites of erosion was significantly reduced (6.6 +/- 1.3 volts, p < 0.05). CONCLUSIONS: A short course of indomethacin therapy produces a patchy decrease in blood flow in the gastric mucosa and erosions were seen in these areas.

OBJECTIVE: To compare gastric mucosal blood flow (GMBF) in normal subjects with that in patients with portal hypertension with or without portal hypertensive gastropathy (PHG). METHODS: GMBF was measured by endoscopic laser-Doppler velocimetry in 20 gastroscopically normal subjects and 30 patients with portal hypertension with or without PHG. The effects of breath-holding (vasomotor reflex), submucosal epinephrine and sublingual isosorbide dinitrate were also studied. RESULTS: In normal subjects, GMBF on the greater curvature was (mean +/- SD) 9.5 +/- 1.3 V and on the lesser curvature, 9.1 +/- 1.9 V. Breath-holding caused a reduction in GMBF by 57.1 +/- 13.7%, submucosal epinephrine reduced it by 41.5 +/- 21.5% and sublingual isosorbide caused a rise of 25.8 +/- 15.2%. The GMBF on the greater and lesser curvature respectively in patients with mild PHG (7.7 +/- 1.2 V and 7.7 +/- 0.8 V) and those with severe PHG (6.5 +/- 3.5 V and 6.3 +/- 2.2 V), was significantly less than that in normal subjects (p < 0.05 and p < 0.001 respectively). Vasomotor reflex was blunted in patients with mild and severe PHG (23.3% +/- 20.3 and 23.1% +/- 17.7 respectively, p < 0.001). Responses to submucosal epinephrine and sublingual isosorbide were similar to those recorded in normal subjects. CONCLUSIONS: Patients with portal hypertension have significantly reduced GMBF and significantly attenuated vasomotor reflex in the gastric vascular bed as compared to normal subjects.

A 27-year-old man, who had symptoms of gastric outlet obstruction, was found on endoscopy to have a large duodenal polyp which on histology was diagnosed as villous adenoma. The tumor was resected surgically and the patient remained asymptomatic until two years later.

Twenty five patients with pemphigus vulgaris were prospectively studied for esophageal involvement by endoscopic examination. Eighteen (72%) had esophageal involvement; the majority of the lesions were bullae. Histological examination showed acantholysis of the cells and exuberant inflammation.
