Possible association of active gastritis, featuring accelerated cell turnover and p53 overexpression, with cancer development at anastomoses after gastrojejunostomy. Comparison with gastroduodenostomy.
(1/77)
To cast light on tumorigenesis in the remnant stomach after distal gastrectomy for peptic ulcer or gastric cancer, 45 cases in gastroduodenostomy (Billroth I, 17 cases) and gastrojejunostomy (Billroth II, 28 cases) groups were compared for a series of parameters. Cancers in Billroth II were significantly more predominant in the anastomosis area and more frequently associated with Epstein-Barr virus infection. Active gastritis, accelerated epithelial cell turnover (as assessed by measurements of apoptosis and cell proliferation), DNA damage, and foveolar cell hyperplasia were all greater in anastomotic areas after Billroth II than in proximal areas after Billroth II or either area after Billroth I. K-ras mutations were rare, but Epstein-Barr virus infection in cancers was seen frequently in anastomosis cases. In conclusion, active gastritis, possibly induced by enterogastric reflux, is linked to tumorigenesis in anastomosis sites in Billroth II cases. (+info)
Assessment and treatment of recurrent peptic ulceration.
(2/77)
From the experience of treating 91 patients with a proven recurrent ulcer we consider that if a proven ulcer is shown to be present and a gastrin-secreting tumour is excluded an appropriate reoperation will almost always produce a successful result (94 per cent). Before subjecting patients to reoperation all attempts must be made to secure a precise diagnosis. The following investigations should be performed: barium meal, panendoscopy of the upper gastrointestinal tract, determination of maximum acid output (with insulin test and gastrin analysis if appropriate), and cholecystography. Before accepting a diagnosis of recurrent ulcer at least 2 of the first 3 tests should be postive. If the primary operation was a resection we advocate vagotomy alone as the second operation, provided there are no local complications such as stenosis, bleeding, or fistula. If the primary operation was a vagotomy and the recurrence is associated with a positive response to the insulin test we advocate revagotomy and antrectomy. If the insulin test is negative we normally repeat the test; if it is still negative then we use antrectomy alone. (+info)
Gastrocolic and gastrojejunocolic fistulae: report of twelve cases and review of the literature.
(3/77)
Seven gastrocolic and five gastrojejunocolic fistulae were recorded at Charity Hospital between 1940 and 1970. Such fistulae occurred in males more often than females. In this series, as in others, the most common cause was gastric surgery for peptic ulcer disease. Pain, diarrhea, and weight loss were clinical findings in half the patients; anemia, leukocytosis, electrolyte disturbances and hypoalbuminemia were common laboratory findings. A fistula was demonstrated radiologically in nine of the twelve patients, management of these patients included no operation (3); two-stage procedure (2); and one-stage procedure (7); with a recent trend toward the one-stage procedure. A case report of a fistula resulting from postoperative complications of perforative appendicitis in which a successful combination of hyperalimentation and diverting colostomy was used is presented.

Gastritis cystica and carcinoma arising in old gastrojejunostomy stoma.
(4/77)
Gastritis cystica and carcinoma developed 35 years after partial gastectomy and gastrojejunostomy for benign peptic ulcer. Although chronic atrophic gastritis and carcinoma are well recognized complications of gastrojejunostomy, gastritis cystica appears to be rare. The resemblance of the lesion to that of colitis cystica profunda is striking. (+info)
Proximal gastric vagotomy: interim results of a randomized controlled trial.
(5/77)
In a randomized controlled trial 50 patients with duodenal ulcer treated by proximal gastric vagotomy (P.G.V.) without drainage were compared with 50 who underwent selective vagotomy and gastrojejunostomy. The clinical results were assessed in 99 patients one to four years after operation. Patients who had undergone P.G.V. had significantly less dumping, nausea, and bile vomiting and fared better in their overall clinical grading. The postoperative Visick grading of the 50 patients with P.G.V. was similar to that of 56 controls with no known gastrointestinal disease who had not undergone operation. The results obtained in the patients who had had P.G.V. without drainage were compared with those of a further group of 24 patients subjected of P.G.V. with gastrojejunostomy, and the better results obtained in the former group were thought to be due to elimination of the drainage procedure. The average follow-up period of the trial was just over two years, but there were no indications that the recurrent ulceration rate after P.G.V. would be any higher than after other types of vagotomy and drainage.

Diagnosis and current management of gastrojejunocolic fistula.
(6/77)
Gastrojejunocolic fistula is a late complication of gastroenterostomy and is associated with inadequate gastric resection and incomplete vagotomy. In the past, attempted primary repair had high mortality and staged operations were normally performed. We present two cases of gastrojejunocolic fistula and discuss the modern management of this condition. In both cases, improved nutritional support allowed successful one-stage surgical repair to be performed. (+info)
Distal antrectomy with vagectomy for duodenal ulcer: results in 611 cases.
(7/77)
Distal antrectomy (25% or less) resection of the distal stomach with bilateral vagectomy, Billroth II, antecolic, Polya or Hofmeister gastrojejunostomy, continues to be our operation of choice for chronic duodenal ulcer. This is based upon our experience in 611 operations and as a result of careful complete repeat in-patient followup studies conducted since our original operation which was devised and performed in July 1953. This procedure controls or eliminates the two major gastric acid stimulatory phases responsible in the pathogenesis and chronicity of a duodenal ulcer: neurogenic (cephalic phase) via the vagel gastric pathways, and the humoral (gastrin) phase via antral stimulation. Even though part of the antrum may remain in the gastric remnant in some patients, antral control is maintained because the antrum remains in the gastric acid stream, there is no stasis, and it is vagectomized. The ulcer diathesis is controlled with a minimal disturbance in gastric physiology, in function, and in gastric reservoir capacity; the procedure will almost eliminate all of the undesirable postoperative gastrointestinal sequelase associated with other operations for duodenal ulcer. It insures the least chance for marginal, gastric, or recurrent ulcer formation, and a low morbidity rate. (+info)
A clinical and statistical study of the effect of gastrojejunostomy on human gastric secretion.
(8/77)
By a statistical study using the Kay augmented histamine test it has been shown that performing a gastrojejunostomy has no fundamental effect on gastric secretion and that the post-operative differences are due entirely to reflux and/or loss through the stoma. (+info)
