Severe secretory diarrhea with elevated gastrin-releasing peptide controlled by somatostatin analogue: a case report.

Gastrin-releasing peptide immunoreactivity has been seen in functioning endocrine tumours which are recognized as a major cause of secretory diarrhea. The authors describe a case of a 52-year-old woman who had secretory diarrhea (5 L/d) with markedly elevated gastrin-releasing peptide levels associated with islet cell hyperplasia. No tumour could be identified. The diarrhea was controlled by somatostatin analogue.

Endoscopy of vertical banded gastroplasty.

Vertical banded gastroplasty is the most common operation for morbid obesity. Postoperative gastroscopy was needed 91 times in 79 of 696 patients for 1) abdominal pain (23), 2) excess vomiting (22), 3) inadequate weight loss (14), 4) excess weight loss (13), 5) and a sudden increase in eating capacity (7). A normal appearance consisted of a clean gastric channel 6.8 +/- 1.4 SD cm long, with a rosette 46.6 +/- 2.1 cm from the incisors and, with insufflation, an 11 mm scope passed through this pseudopylorus snugly, but without difficulty. In Group 1, no problem was seen in the channel, and cholecystitis was found to be the cause. In Group 2, no problem was observed in ten (poor teeth and chewing), six experienced stasis or pill ulcerations, four had bezoars (fragmented or removed with basket), and two had intraluminal mesh. In Group 3, the scope floated through too large an outlet (greater than or equal to 13 mm) in eight, and no cause was seen in six (gorgers, sweets-eaters). In Group 4, tightness or stricture resolved with dilatations (Eder-Puestow; Savary; balloon dilators) in six, but seven required re-operation. In Group 5, the scope travelled through four breakdowns in the partition and three outlets were too large. Gastroscopy viewed problems accurately, indicated treatment and suggested modifications in gastroplasty technique.

Percutaneous endoscopic gastrostomy by the "pull" and "introducer" methods.

After 28 patients, studied prospectively, underwent percutaneous endoscopic gastrostomy (PEG) by the Ponsky "pull" technique, another 28 patients underwent PEG by the Russell "introducer" method. These two groups were compared retrospectively with 28 patients who had previously undergone Stamm gastrostomy as an independent operation performed by the same group of surgeons. All procedures were done within a 5-year period. The major indication for gastrostomy was the inability to swallow due to neurologic diseases; a similar number of patients in each group also had pharyngeal blockage, cachexia, respiratory failure and inhalation burns. Percutaneous endoscopic gastrostomy could be done most appropriately under local anesthesia, the "introducer" method requiring less time than the "pull" method, which in turn required less time than the Stamm gastrostomy. Feeding was generally instituted successfully 24 hours after PEG compared with 3 days after Stamm gastrostomy. "Introducer" PEG was not associated with peristomal infection, and the authors postulate that the peristomal infections in the "pull" PEG group were due to oropharyngeal bacteria brought through the abdominal wall by that technique.

Modern management of cervical scrofula.

From 1970 to 1984, 32 patients were treated for tuberculous (TB) masses, which measured 1.2-5.5 cm. The posterior triangle was involved in 19 patients, anterior triangle in 7, and more than one triangle in 6 (3 bilateral). A superficial node was excised for diagnosis. Acid-fast bacilli were identified on the smear of 18 patients. Caseation necrosis was present in 27 specimens, sarcoidosis in four, nonspecific lymphadenitis in one; all cultures grew Mycobacterium tuberculosis. A chest x-ray showed no active TB. Chemotherapy was given for 9-18 months (9 months when only one node was diseased and 18 months with extensive nodal involvement). Follow-up examinations in all patients (greater than 3 years, mean 8.6 years) has revealed no recurrence. The need to excise all cervical TB nodes, chronically inflamed and often fused to important structures, was eliminated by adequate chemotherapy.
