To avoid proximal gastrectomy which destroys the gastroesophageal closing mechanism, modified segmental gastrectomy with vagotomy was performed on 3 patients with gastric ulcers located in the stomach near the gastro-esophageal junction. These were all patients in whom a proximal gastrectomy would usually have been performed. The proximal line of resection did not encroach upon the mucosal rosette being within 1 cm of it following the margin of the ulcer. In each patient, the modified segmental resection of the upper stomach consisted of the surgical removal of a continuous strip of tissue including the ulcer and ulcer-bearing area along the wall followed by an end to end gastro-gastrostomy. In the 10 years following surgery, there have been no signs of reflux esophagitis, stricture, or recurrent ulcers in any of the 3 patients. This modified segmental gastrectomy with vagotomy is therefore recommended for gastric ulcers located near the gastro-esophageal junction. 相似文献

The purpose of this study was to examine the preventive and therapeutic effects of vagotomy on the stress-induced ulcer in
terms of gastric submucosal blood flow and ulcer index. Stress was induced in male Wistar rats by forced immersion in water,
and the gastric submucosal blood flow (hydrogen clearance method) and ulcer index were determined in animals that underwent
truncal vagotomy alone or truncal vagotomy+pyloroplasty as well as in untreated controls. Both truncal vagotomy alone and
truncal vagotomy+pyloroplasty were effective in maintaining the blood flow during stress and preventing the development of
ulcers, however, these effects were more notable in the truncal vagotomy+pyloroplasty animals. Truncal vagotomy alone or truncal
vagotomy+pyloroplasty performed after the development of stress-induced ulcers had no therapeutic effects. 相似文献

We investigated the postperative results of distal partial gastrectomy, selective vagotomy plus antrectomy, and selective
proximal vagotomy, to evaluate their effectiveness in the treatment of duodenal ulcers. The operative mortality of selective
vagotomy plus antrectomy and selective proximal vagotomy seemed to be lower when compared to distal partial gastrectomy, although
each procedure showed a sufficiently low mortality. The acid reduction rate was significantly lower after selective proximal
vagotomy than after the other procedures (p<0.01). However, the rate of ulcer recurrence following selective proximal vagotomy
tended to be higher compared with the other procedures. All three procedures showed good results according to Visick’s grading
and postoperative symptoms occurred in about 50 per cent of all patients, no matter what the procedure. The regaining of physical
ability was significantly greater following selective proximal vagotomy than following distal partial gastrectomy (p<0.05)
and the capacity to work was also better after vagotomy, particularly selective vagotomy plus antrectomy (p<0.05). Thus, although
distal partial gastrectomy and selective vagotomy plus antrectomy proved superior regarding the low ulcer recurrence rate
and acid reduction, while selective proximal vagotomy proved superior for improving the quality of life, on the whole the
three operations promise almost equivalent results. 相似文献

The role of vagotomy for healing of gastric ulcer is obscure. To investigate the effect of vagotomy on healing of experimentally-induced
gastric ulcer, a mucosal defect of a constant size was made in the gastric fundus of control rats and other rats subjected
to abdominal bilateral vagotomy. Gastric acid secretory response to electrical stimulation of the cervical vagus nerve and
changes in body weight and in ulcer index (mm 2) were estimated postoperatively, in these groups. Significant acid secretory responses to the vagal stimulation and constant
weight gain were observed in the control rats while there was no acid secretory response and a lesser weight gain in the vagotomized
rats than in the controls. There were no significant differences of postoperative ulcer indices between the two groups. These
results suggest that the procedure does not alter gastric mucosal circumstances related to the healing of the gastric ulcers,
although vagotomy abolishes the cephalic phase of gastric acid secretion. 相似文献

Gastric emptying has been reported to be both delayed and unchanged following posterior truncal vagotomy combined with anterior
seromyotomy (PTV + AS). When compared to highly selective vagotomy (HSV), our clinical experience was that PTV + AS not uncommonly
produced postprandial distress. We studied gastric emptying of both liquids and solids 3 and 12 months following HSV and PTV
+ AS to determine what if any differences there were in gastric emptying between the two procedures. We compared these results
with those from studies done in both normal subjects and unoperated duodenal ulcer patients. In 26 duodenal ulcer patients
with perforation ( n = 18) or bleeding ( n = 8), who were treated with HSV ( n = 10) or PTV + AS ( n = 16), gastric emptying of liquids and solids was evaluated at 3 months and 12 months postoperatively. At 3 months, gastric
emptying of liquids was delayed in both the HSV and PTV + AS groups as compared to values in both normal subjects and unoperated
duodenal ulcer patients. The emptying of solids was markedly delayed by PTV + AS in contrast to HSV at 3 months (167.1 ±28.4
minutes vs. 79.9 ±16.7 minutes; P <0.05). The lag duration was not affected. A limited number of patients studied at 12 months
showed similar and near-normal emptying of solids in both the HSV and PTV + AS groups (67.5 ±7.0 minutes vs. 70 ±6.6 minutes).
PTV + AS in contrast to HSV produces more marked delayed emptying of liquids and solids at 3 months; with time (1 year) these
values return to near normal.

Summary The endoscopic Congo red test (ECRT) was performed in 43 patients who underwent proximal gastric vagotomy (PGV) for duodenal ulcer (DU). The aim of the study was to develop a standard and reliable way to interpret the results obtained in this test. Thus, the results of ECRT were related to post-operative clinical evaluation and to pre- and post-operative basal and pentagastrin-stimulated gastric acidity. Whenever ECRT was considered positive, we called it in large extension if a red-to-black colour change occurred in three or more of the areas studied. Positive ECRT was observed in 39 patients (90.7%). There was a statistically significant ( P<0.01) correlation between poor clinical results and positive ECRT in large extension. We concluded that: (1) a positive ECRT result has no clinical or prognostic significance in DU patients after PGV; (2) ECRT, analysed according to the extension of the areas turning black, is a practical and reliable method to establish clinical results and prognosis in these patients. 相似文献

Rats were prepared with modified Heineke-Mikulicz pyloroplasty with longitudinal seromuscular incision, centering at pyloric
ring, separation of submucosal layer around the pylorus and addition of transverse closure. This procedure combined with vagotomy
was applied to the rats with cortisone administration and obstructive jaundice or exposure to the restraint plus cold water
stress. Pyloroplasty and vagotomy seemed to prevent the occurrence of the severe damage on gastric mucosa without any suture
line leakage whereas. Control rats had often erosive gastritis or hemorrhage. 相似文献

Summary In this prospective study, minimally invasive methods of proximal gastric vagotomy (PGV) were investigated in male Sprague-Dawley rats. Completeness of vagotomy by traditional operative therapy, by laser denervation of the gastric serosa, and by subserosal or transmucosal injections of chemoneurolytic agents was evaluated with postoperative Congo red testing, ulcerogenic stimulation of the gastric mucosa, and histochemical labeling of whatever vagal fibers remained in the gastric wall. Short-term results demonstrate that successful PGV can be performed with minimally invasive methods. 相似文献

The choice of operation for acute hemorrhagic postbulbar duodenal ulcer after an operation is discussed. Distal partial gastrectomy
was performed in six patients. The ulcer was treated by resection, suture, or removal by mucoclasis. Hemostasis was attained
in five patients. In another, multiple ulcers were observed in the descending portion of the duodenum and gastrectomy failed
to control hemorrhage, resulting in death. Rebleeding was observed in two, one from a newly formed ulcer in the upper part
of the papilla of Vater after gastrectomy with truncal vagotomy and which was halted by suture of the ulcer and another was
from a newly formed ulcer in the remnant stomach after gastrectomy and which was halted by selective vagotomy and ligation
of the left gastric artery. It is recommendable to perform a subtotal gastrectomy and vagotomy combined with removal of the
ulcer by mucoclasis or ulcer suture. In some cases, pancreatoduodenectomy may have to be done. 相似文献

Background Laparoscopic-assisted gastric surgery has become an option for the treatment of early gastric cancer. However, there are few
reports of laparoscopic surgery in the management of advanced gastric cancer. In this study we describe our experience with
laparoscopic-assisted distal gastrectomy (LADG) for advanced gastric cancer (AGC).
Methods Between November 2004 and June 2007, 47 patients with AGC underwent LADG at our hospital, and 45 of those patients were enrolled
in this study. These patients were compared with 83 patients who had AGC and underwent conventional open distal gastrectomy
(ODG) during the same period.
Results Operation time was significantly longer in the LADG group than in the ODG group. Estimated blood loss in the LADG group was
significantly less than in the ODG group. Time to ambulation and first flatus and duration of analgesic medication were significantly
shorter in the LADG group. The morbidity and mortality rate were also lower than in the ODG group, with no statistically significant
difference. The distance of the proximal resection margin showed no significant difference compared with ODG (6.3 ± 0.9 versus
6.5 ± 0.9 cm; p = 0.228). The mean number of nodes resected with LADG was 35.6 ± 14.2, and that with ODG was 38.3 ± 11.4 ( p = 0.269). The mean follow-up for the LADG group was 23.6 months (range 9–40 months). In the LADG group, recurrence was observed
in six patients (13.3%). Three patients had recurrence and died after 10 (IIIB), 11 (IIIA), and 13 (IIIB) months.
Conclusions LADG with extended lymphadenectomy for AGC is a feasible and safe procedure and has several advantages. Moreover, this method
can achieve a radical oncologic equivalent resection. Indications for LADG with extended lymphadenectomy could be expanded
in the treatment of locally advanced gastric cancer. 相似文献

We report herein the case of a 65-year-old man who developed non-Hodgkin's lymphoma of the gastric stump 9 years after undergoing a distal gastrectomy for a gastric ulcer. The patient presented with epigastric discomfort, and an upper gastrointestinal series and gastroscopy revealed a lymphoma lesion located close to the site of his gastroduodenal anastomosis. A total gastrectomy was performed, followed by combination chemotherapy, comprised of vincristine, Endoxan, prednisone and Adriamycin (VEPA). Histologically, the resected specimen was diagnosed as non-Hodgkin's lymphoma. The patient has :remained well without any signs of recurrence for 18 months since his operation. Although there have been a number of reports of adenocarcinoma devoloping in the gastric stump following surgery for peptic ulcers, the development of malignant lymphoma under such conditions is rare. Following the presentation of this case, we review the available literature and discuss the possibility of malignant lymphoma developing in the gastric stump. 相似文献

Background: Recently, gastric stapling with posterior truncal vagotomy has been performed, either by conventional or laparoscopic surgery, as an alternative to highly selective vagotomy and the Taylor procedure for the treatment of chronic duodenal ulcer. Our aim was to investigate the longterm effects after a stapling-modified Taylor procedure, conventional and laparoscopic, on gastric secretion and emptying and on clinical indices and recurrence rates in patients treated for duodenal ulcer before 1994. Study Design: Thirty-one patients, aged 40 to 76 years (mean 53 years), were treated between 1986 and 1993, 21 by conventional and 10 by a laparoscopic stapling-modified Taylor procedure. Outcomes were studied for gastric acid secretion, solid and liquid gastric emptying, euterogastric reflux, endoscopic findings, and clinical indices using the Visick grading. Results: Endoscopy revealed a healing ulcer in 29 patients. Two patients showed signs of chronic ulcerative disease with mild symptoms, without gastritis or pyloric stenosis indicative of progressive ulcerative diathesis, and were classified as Visick III. Twenty-four patients were classified as Visick I and 5 as Visick II. The enterogastric reflux index ranged from 0% to 27%, and basal and peak acid output were 1.5 ± 0.6 mmol H+/h and 12.2 ± 6.4 mmol H+/h, respectively. The half-emptying time of solid and liquid meals was 78 ± 9 minutes and 18 ± 6 minutes, respectively. These results are likely to be similar to those obtained from the series of patients who underwent highly selective vagotomy or Taylor procedure and are close to those achieved in healthy controls. Conclusions: This modification of the original Taylor operation (conventional and laparoscopic) allows a more rapid, technically easier, and radical performance of the operation with excellent longterm results and should be considered an effective alternative for the treatment of duodenal ulcer. 相似文献

BackgroundGiven the rise of medical treatment for peptic ulcer disease (PUD), surgical treatment is necessary only in select cases and emergencies. The authors assess the current relevance of surgical vagotomy to treat PUD and its complications. Data SourcesAlthough historically significant, selective and highly selective vagotomy is very technically challenging, and highly selective vagotomy has a relatively narrow indication and high recurrence rates. Vagotomy and gastrectomy is associated with significant side effects. Two types of vagotomy remain relevant, within a narrow scope. Truncal vagotomy and pyloroplasty is safe and efficacious through a laparoscopic approach in certain emergent cases. Vagotomy and Roux-en-Y gastrojejunostomy can be used to treat severe PUD refractory to medical management. ConclusionsThe role of vagotomy in the management of PUD has a rich history but predated pharmacologic control of acid and understanding of the role of Helicobacter pylori in the disease. Thus, the current role of vagotomy is significantly limited. Specifically, the emergent use of truncal vagotomy is warranted for patients who are either resistant or allergic to proton pump inhibitors. 相似文献

OBJECTIVES: We analyzed our experience with the laparoscopic approach for treating benign gastric lesions. METHODS: Between June 1998 and June 2002, we performed 18 gastric resections with the laparoscopic approach for 7 pyloric stenoses, 8 recurrent duodenal ulcers, and 3 chronic gastric ulcers. RESULTS: In our series, we performed Billroth II laparoscopic distal gastrectomy with no morbidity and mortality. CONCLUSIONS: Billroth II laparoscopic distal gastrectomy is safe in cases of benign gastric or duodenal lesions. 相似文献
