A prospective randomized trial of vagotomy in chronic duodenal ulceration: 4-year follow-up.

A total of 153 patients (124 male and 29 female) with uncomplicated chronic duodenal ulceration were studied in a prospective, randomized trial of proximal gastric vagotomy (PGV) and truncal vagotomy and pyloroplasty (TVP), conducted in four Manchester hospitals. Of these, 137 patients have now been followed up for 2.5 to 5.5 (mean 4.1) yr. There have been 15 (21 per cent) recurrent ulcers following PGV compared with 5 (7.5 per cent) after TVP (P less than 0.05). A satisfactory functional result was obtained in 82 per cent of patients after TVP compared with 73 per cent following PGV and there was little difference between the groups with regard to the incidence of dumping, heartburn and vomiting. There was significantly more diarrhoea following TVP (13 per cent) compared to PGV (1.4 per cent) but this represented only a minor clinical problem.

Randomized trial of elective highly selective or truncal vagotomy in chronic duodenal ulceration.

Between 1973 and 1976, 153 patients (124 men, 29 women) with uncomplicated, chronic, duodenal ulcer were entered into a prospective randomized trial of highly selective vagotomy (HSV) or truncal vagotomy and pyloroplasty (TVP). The study was conducted in four Manchester hospitals and the operations were performed by consultants or chief registrars. The follow-up was conducted by personal interview using a standardized questionnaire. The medical gastroenterologist did not know which type of operation the patient had had. The patients who had symptoms were referred back to the surgeon who performed the operation. The clinical laboratory and follow-up data were analysed by computer. There were no operative deaths. Three patients died from unrelated causes, 13 were lost to follow-up; 137 (89.5%) were followed up for a mean of 4.1 years (range from 2.5 to 5.5 years). A modified Visick grading was used to assess the results of surgery. The outcome was good in 82% after TVP and 73% after HSV. This difference and those in the incidences of early or late postprandial dumping, bilious vomiting, weight loss, anemia and heartburn were not significant. Diarrhea was more frequent after TVP (13.4%) than after HSV (1.4%); although the difference was significant (p less than 0.025), this complaint did not present a serious clinical problem. Ulcers recurred in 15 (21.4%) patients following HSV and in 5 (7.5%) after TVP; this difference was statistically significant (p less than 0.05).

Cimetidine and gastric cancer.

Three patients with dyspeptic symptoms who were being treated with the H2-receptor blocking drug, cimetidine, were later found to have gastric carcinoma. It was not possible to determine whether the association was fortuitous, whether the drug had masked the neoplastic change, or whether it was involved in some other way. Repeated clinical and endoscopic evaluation is essential in patients on this treatment for any length of time.

A prospective randomized trial of vagotomy in chronic duodenal ulceration.

In a prospective, randomized trial, 76 patients with duodenal ulceration treated by truncal vagotomy and pyloroplasty were compared with 77 patients who underwent highly selective vagotomy. A total of 149 patients was followed up for from 1 to 4 years, the average follow-up period being 2.6 years. There was no operative mortality and no significant difference in postoperative morbidity between the two groups. The incidence of recurrent ulceration was greater after highly selective vagotomy, but this difference was not statistically significant. The clinical results were comparable in each group, and although the incidence of diarrhoea and dumping was greater after vagotomy and pyloroplasty, this difference was not statistically significant.

Comparison of an intragastric method of estimating acid output with the pentagastrin test in normal and duodenal ulcer subjects.

Using Fordtran's technique but substituting the meat extract Oxo for the steak meal we investigated gastric acid secretion in eight control subjects and nine patients with chronic duodenal ulcer. Intragastric titration was performed using a double lumen tube measuring the pH in the stomach every three minutes and adjusting it to 5.5 throughout the test by infusing 0.3-M sodium bicarbonate. On a separate day a pentagastrin test was performed using a conventional gastric aspiration technique. In the eight control subjects the mean acid output after pentagastrin was 13.7 +/- 2.1 (SEM) mmol/h, whereas the mean hourly acid output measured by intragastric titration was 20.1 +/- 3.1. The greater response to Oxo than to pentagastrin in the controls (deltaAO = + 46%) was significant (P less than 0.01). This is in contrast with our duodenal ulcer patients whose mean hourly acid outputs were 22.7 +/- 4.4 and 23.0 +/- 4.4 mmol/h in response to pentagastrin and Oxo respectively (r = 0.95). The findings, while clearly at variance with those of Fordtran and Walsh (1973), are more in keeping with the concept of increased endogenous secretory drive in duodenal ulcer patients compared to normal subjects.

Effect of urogastrone in the Zollinger-Ellison syndrome.

The effects of human urogastrone (0-25 mug. per kg. per hour intravenously) in four male patients with proven Zollinger-Ellison syndrome (z.e.s.) and in four healthy control subjects have been studied. After urogastrone in z.e.s. patients gastric acid volume and concentration decreased and basal acid output was reduced by 50-82%; the concentrations of intrinsic factor and pepsin in gastric juice increased by 60-300%; and peak plasma-gastrin concentration increased by 127-164% of basal concentration. A significant negative correlation between increase in plasma-gastrin concentration and decrease in acid output was observed (r=-0-72, P less than 0-01). Ulcer pain was relieved 30-60 minutes after the beginning of urogastrone infusion. These results suggest that urogastrone can inhibit the endogenously stimulated acid hypersecretion in z.e.s.

Effect of urogastrone on gastric secretion and plasma gastrin levels in normal subjects.

Purified human urogastrone was given by intravenous infusion to 12 normal volunteer subjects and measurements made of gastric acid, pepsin and intrinsic factor secretion, and of plasma gastrin concentration. Clinical, haematological, and biochemical screening tests were made throughout the period of study. Urogastrone inhibited acid and intrinsic factor secretion whether stimulated by pentagastrin, histamine, or insulin, but had a much less marked effect on gastric pepsin output. Plasma gastrin levels did not alter significantly. Limited dose-response studies showed that 0-25 mug urogastrone kg--1 hr--1 resulted in inhibition of acid output of 80% and was not associated with clinical side-effects. No significant alteration in any of the haematological or biochemical measurements was observed in any of the subjects.

Treatment of haemorrhoids by rubber band ligation.

Outpatient treatment of haemorrhoids by elastic band ligation without anaesthetic was performed in 75 patients. Clinical review showed that 65 returned to work within 24 h of ligation, 8 in 48 h and 2 after 48 h. No patient required hospitalisation for either rectal bleeding or pain after ligation. In the first week after treatment 36 were completely symptom-free, 26 had minimal discomfort and 13 had moderate pain with a sense of imcomplete evacuation in the rectum, and some frequency of call to stool lasting up to 7 days in 1. Follow-up at 8-26 months (mean 10 months) showed that 59 were symptom free, only occasional rectal bleeding occurred in 7 and more frequent irregular bleeding in 2. Religation of residual haemorrhoids was performed in 7 and 2 and a haemorrhoidectomy. For the majority of patients hospitalisation and loss of work were avoided.
