Endoscopic removal of stone in patients with retained common bile duct stone and T-tube after cholecystectomy. Is it justified?

Fifteen patients with retained common bile duct (CBD) stones and T-tube and twenty patients with CBD stones without T-tube had stones removed by endoscopic method. The result of endoscopic sphincterotomy, stone extraction, stone clearance and complication in patients with T-tube was similar to the results in patients without T-tube. The presence of T-tube did not create much difficulty in stone removal and the successful rate of 86.6 per cent (13/15) was satisfactory. Endoscopic removal of retained stones in patients with T-tube is recommended when retrieval via T-tube is not available since the later has fewer reported complications with very low mortality compared to the endoscopic technique.

Liquid meal emptying in non-ulcer dyspepsia: a study in 22 Thai patients.

Twenty-four patients with non-ulcer dyspepsia (NUD) were recruited for gastric emptying study of liquid meal before and after 1 week's treatment with domperidone (80 mg in 19, 40 mg in 2, dropout 1 and excluded 2). Delayed gastric emptying was found in 8 of 22 (36.36%). Clinical improvement was found in 11 patients after treatment. Gastric emptying improvement was found in 3 patients (2 without clinical improvement). No correlation was found between the clinical and gastric emptying improvement. (Fisher exact test p greater than 0.25). Impaired liquid emptying is common in NUD and domperidone improved clinical symptoms in 50 per cent of NUD in this study.

The magnitude of nocturnal acid suppression by ranitidine 300 mg given at 18.00 hours.

Ranitidine 300 mg given at 18.00 hours in 5 patients with CVA resulted in 99.5 per cent acid suppression for 12 hours. Intragastric pH of 4 or greater was obtained in only 58 per cent of the 12-hour period. An early evening dose of ranitidine is probably more effective and dosage reduction may be applicable for the healing of duodenal ulcers. However, ranitidine as given in this study is probably not adequate for stress ulcer prophylaxis.

Tetracycline-induced esophageal ulcer: a condition that probably more common than it appears to be.

Ten cases of tetracycline derivatives related drug induced esophageal ulceration were described. Five cases were due to minocycline and another five were due to doxycycline. Recumbent posture after drug ingestion was one of the predisposing factors. Odynophagia was the main symptom but may not be the presenting symptom. The diagnosis was easily confirmed by endoscopy. Single-contrast barium study was not sensitive for the demonstration of the esophageal ulcers. The recommended treatment includes cessation of the offending drug and symptomatic treatment. All recovered without any sequela within 3 to 11 days. The most important measure to prevent this condition is to instruct patients to take drugs in the upright position with at least 100 ml of water.

Medication-induced esophageal injury: report of 17 cases with endoscopic documentation.

We report on medication-induced esophageal injury (MIEI) in 17 patients (six male, 11 female) seen from October 1986 to May 1990. The mean age of patients was 27.3 (SD = 5.7) yr; mean duration of drug ingestion prior to the occurrence of symptoms 10.2 (SD = 11.5) days, and mean duration of symptoms before seeking medical attention 4.6 (SD = 3.8) days. Symptoms subsided after treatment, with a mean of 6 (SD = 2.5) days. Symptoms included odynophagia (in 17), chest pain (six), epigastric pain (three), and retrosternal pain (one). Symptoms occurred after the drug was stopped in three. MIEI was caused by doxycycline (seven), minocycline (five), Pantozyme (one), cloxacillin (one), unknown (two), and dicloxacillin + Danzen (one). Reclining after drug ingestion was the predominant risk factor. Endoscopy showed most ulcers to be multiple and at midesophagus. Barium swallows done in two patients were negative. There is no previous report of Pantozyme (pancreatic enzyme), Danzen (serratio-peptidase), cloxacillin, and dicloxacillin causing MIEI.

Gastrointestinal lesions in patients over 40 years of age with iron deficiency anemia and hookworm infection.

A prospective study of 41 patients (24 male and 17 female) aged over 40 years with iron deficiency anemia and hookworm infection was performed by endoscopy and barium enema to determine the incidence of GI lesions. Alcohol ingestion, smoking, abdominal pain, anorexia, loss in weight, bowel habit change, analgesic consumption and stool occult blood test were analyzed for their positive predictive value of GI lesions. The mean age of the patients was 62.8 years (SD = 10.1). The mean hemoglobin was 5.99 gm.% (SD = 1.9). Twenty patients (48.8%) had GI lesions. The lesions included 10 erosive gastritis, 1 erosive duodenitis, 5 gastric ulcers, 2 duodenal ulcers, 1 carcinoma of stomach and 1 carcinoma of colon. Gastric ulcer, duodenal ulcer and carcinoma were regarded as significant lesions. Abdominal pain was found in 16 of the 20 patients with GI lesions and 8 of the 21 without GI lesion (Chi square with Yate's correction, x2 = 5.78 p = 0.02). Four of the 17 patients without pain had GI lesions but only one of these 4 (5.8%) had gastric ulcer. Abdominal pain had an 80% sensitivity and 62% specificity for the positive prediction of GI lesions based on the above findings. GI investigation is recommended for all patients with abdominal pain. In those without pain, treatment of hookworm and iron therapy with follow-up may be justified.

Pneumatic dilatation for achalasia of the esophagus: report of three patients treated with self-constructed pneumatic bags using the endoscopic technique.

Three patients with achalasia of the esophagus treated with pneumatic bag dilatation were reported. The preliminary result is encouraging. To what extent the difference in the type of bags and technical variations contributed to the ultimate outcome of the treatment is not known. The endoscopically aided pneumatic dilatation was found to be safe and simple.

Peptic stricture of the esophagus: report of a case with perforation and Barrett's esophagus.

A 79-year-old man with peptic stricture of the esophagus was treated by endoscopic aid dilatation using Eder-Peustow dilator. Esophageal perforation was suspected after the second dilatation and conservative treatment was initiated with full recovery. The patient developed Barrett's esophagus despite continuous treatment with ranitidine and metoclopramide. The role of medical treatment in esophageal perforation due to instrumentation was emphasized. Peptic stricture of esophagus is probably not common in our community. The conventional treatment of esophagitis with ranitidine and metoclopramide is not adequate in preventing the occurrence of Barrett's esophagus.
