Vagotomy and Pyloroplasty for Gastric Ulcer

In a series of 68 patients with gastric ulcer who were treated by vagotomy and pyloroplasty there were no operative deaths, though one patient who received massive transfusions died 14 weeks later from hepatic necrosis probably associated with serum hepatitis. Four patients developed recurrent peptic ulceration requiring further surgical treatment. The clinical condition of all but three of the remainder was satisfactory after an average follow-up period of three years and two months. Of the 14 patients who presented with an acutely bleeding gastric ulcer, one subsequently required gastrectomy for continued bleeding; in all the others the immediate and long-term results were satisfactory. Of 21 patients with a “high” ulcer and 29 with combined gastric and duodenal ulceration one (4·8%) and three (10%) respectively suffered recurrences. We conclude that vagotomy and pyloroplasty is a satisfactory form of treatment for a high or bleeding gastric ulcer, but that for all other gastric ulcers some form of gastric resection is preferable.     

Mortality after Vagotomy and Pyloroplasty for Duodenal Ulcer

A retrospective survey of 4,026 patients having truncal vagotomy and pyloroplasty for duodenal ulceration showed a mortality rate of 1·4% (55 patients). On analysis the commonest causes of death were found to be bronchopneumonia 37% (18 patients) and sepsis 20% (10 patients). More than half of the deaths occurred in patients aged over 50.     

Selective Proximal Vagotomy with and without Pyloroplasty

The early results of a prospective randomized clinical trial of selective proximal vagotomy with and without gastric drainage in a total of 36 patients are reported. In spite of adequate average acid reduction and little evidence of gastric retention two definite recurrent ulcers have occurred in the 16 patients who did not have a pyloroplasty. Further trials of the effect of selective proximal vagotomy without gastric drainage are necessary before the procedure is widely adopted.     

Incidence of Dumping after Truncal and Selective Vagotomy with Pyloroplasty and Highly Selective Vagotomy without Drainage Procedure

The incidence of dumping after truncal or selective vagotomy with pyloroplasty and highly selective vagotomy without a drainage procedure was assessed both clinically and experimentally. At a gastric follow-up clinic dumping was found to be significantly less frequent in patients who had undergone highly selective vagotomy without a drainage procedure than in patients who had undergone truncal or selective vagotomy with pyloroplasty (P < 0·05 or < 0·001, respectively). Hypertonic glucose given by mouth provoked the onset of dumping in 20% of patients with duodenal ulcer before operation, in 73% after truncal vagotomy and pyloroplasty, in 80% after selective vagotomy and pyloroplasty, and in 47% after highly selective vagotomy. The test meal also produced significantly greater decreases in blood pressure and increases in pulse rate in patients who had undergone vagotomy with pyloroplasty than in patients who had undergone highly selective vagotomy.     

Gastric Stasis and Gastric Ulcer after Selective Vagotomy Without a Drainage Procedure

Two independent trials of selective vagotomy without the addition of a drainage procedure in the treatment of uncomplicated duodenal ulcer have shown that gastric stasis may occur after the operation and that in some cases this may be complicated by gastric ulcer. These findings do not support the contention that selective vagotomy alone allows normal gastric emptying.     

Five- to Eight-year Results of Truncal Vagotomy and Pyloroplasty for Duodenal Ulcer

From January 1963 to December 1965 inclusive 192 men with duodenal ulcer were treated by elective truncal vagotomy and pyloroplasty with one death. Ten subsequent deaths were due to causes unrelated to the ulcer or operation, and 17 patients became untraceable. The remaining 164 patients have been followed up for five to eight years. The late results have been compared with those obtained in a previous study of patients five to eight years after truncal vagotomy and gastroenterostomy, truncal vagotomy and antrectomy, and subtotal gastrectomy respectively for duodenal ulcer.Of the various postgastric operation syndromes early dumping, late dumping, bilious vomiting, and diarrhoea were all less frequent, but not significantly so, after vagotomy and pyloroplasty than after vagotomy and gastroenterostomy.Recurrent ulceration was commoner after vagotomy and pyloroplasty than after all the other operations, the incidence of proved and suspected recurrent ulcers being respectively 6·7 and 7·3% after vagotomy and pyloroplasty, but only 2·5 and 5·9% after vagotomy and gastroenterostomy, 0 and 5·2% after vagotomy and antrectomy, and 0·9 and 3·7% after subtotal gastrectomy. The differences between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy are statistically significant, but those between vagotomy and pyloroplasty and vagotomy and gastroenterostomy are not.Overall assessment (Visick grading) of the outcome gave poorer results after vagotomy and pyloroplasty than after any other operation, with 14% of category IV cases after vagotomy and pyloroplasty, 11% after vagotomy and gastroenterostomy, 8% after vagotomy and antrectomy, and 6% after subtotal gastrectomy—differences that are significant between vagotomy and pyloroplasty and vagotomy and antrectomy or subtotal gastrectomy but not between vagotomy and pyloroplasty and vagotomy and gastroenterostomy.In the light of these findings it is suggested that truncal vagotomy and pyloroplasty has not lived up to expectations and its place as the currently most popular procedure in the elective surgical treatment of duodenal ulcer should be reconsidered.     

Vagotomy for Gastric Ulcer

Out of a series of 75 patients who were treated by vagotomy and drainage for gastric ulcer 66 have been followed up for one to seven years (average three-and-a-half years). Four recurrent gastric ulcers occurred among the 33 cases of ulcer of the lesser curve or body with no antral or duodenal lesion (type I). Among the 42 patients with an antral ulcer or an associated active or healed pyloric or duodenal lesion (type II or III) there was only one recurrence. The recurrence rate for men was 5% and for women 12%. One patient died two years after operation from cancer which may have originated in the stomach. The clinical results in patients without recurrences were generally satisfactory.Vagotomy, preferably selective, with drainage is a satisfactory operation in gastric ulcers of types II and III. For ulcers of type I, gastrectomy is to be preferred except in selected cases.     

Emergency Vagotomy and Pyloroplasty for Perforated Duodenal Ulcer: Study of 73 Cases

Seventy-three unselected patients with perforated duodenal ulcer were treated by vagotomy and pyloroplasty in a six-year period. Postoperative complications were commoner when the operation was carried out after more than six hours after perforation. The follow-up results were similar to those for elective vagotomy and pyloroplasty carried out in the hospital during the past nine years.     

Vagotomy or Gastrectomy for Gastric Ulcer

Patients treated in a randomized controlled comparison of management of benign gastric ulcer of the body of the stomach, comprising 50 patients treated by Billroth I partial gastrectomy and 50 patients treated by vagotomy and pyloroplasty and biopsy of the ulcer, were followed up for about five years (range one and a half to eight and a half years). No statistically significant difference has been found between the functional results (Visick grading) of the two groups. There was no operative mortality. Postoperative morbidity (17 against 5) and length of stay in hospital (14 against 10 days) were significantly greater after gastrectomy. Seven patients after vagotomy have been submitted to gastrectomy (three for recurrent gastric ulceration, three for gastric cancer, and one for bleeding), which is a statistically significant excess compared with no reoperation after gastrectomy. While vagotomy and pyloroplasty can be useful to avoid a technically difficult gastrectomy, it cannot be said to replace partial gastrectomy in the treatment of gastric ulcer.     

功能性消化不良患儿Hp 治疗前后的症状及胃排空变化的超声观察

目的:探讨功能性消化不良患儿(Functional Dyspepsia,FD)幽门螺杆菌(Helicobacterpylori,Hp)治疗前后的症状及胃排空变化的超声观察。方法:选择我院6~10岁FD小儿患者70例为FD组,将其中28例Hp阴性者作为Hp阴性组,其余42例Hp阳性者作为治疗组。选取健康小儿72例作为对照组。超声测量入选者服用试餐即刻、20、40、60、90 min的近端、远端胃区面积,计算胃半排空时间。结果:FD组患儿上腹疼痛、上腹烧灼感、腹胀、恶心、嗳气和早饱症状的发生率均高于对照组,差异具有统计学意义(P0.05);FD组近端、远端、全胃的半排空时间均较对照组慢,差异具有统计学意义(P0.05)。腹胀、嗳气和早饱是远端胃半排空延迟的危险因素(OR1,P0.05);腹胀和上腹疼痛是全胃半排空延迟的危险因素(OR1,P0.05)。Hp阴性组、Hp治疗组近端、远端、全胃半排空时间较常规治疗组短,差异有统计学意义(P0.05);Hp治疗组与Hp阴性组之间差异无统计学意义(P0.05)。结论:FD患儿的胃排空有所延迟,对Hp感染患儿进行Hp根治有助于消化不良症状的改善,在临床工作中可合理选择应用。     

Effect of Metoclopramide on Gastric Emptying during Labour

The effect of a single dose of metoclopramide (Maxolon) on the gastric emptying rate of a liquid test meal was measured in a group of parturient women by a double-sampling dye-dilution technique. The subjects were given either metoclopramide 10 mg or sterile water by intramuscular injection on a double-blind random basis at the start of the test. The gastric emptying rate was significantly increased in those women who had received the metoclopramide as compared with those who had received the placebo.
