Abstract
The incidence and severity of postvagotomy diarrhoea has been studied in 32 patients who had undergone both vagotomy and cholecystectomy. Sixteen of these patients had had a proximal gastric vagotomy and 16 a truncal vagotomy and pyloroplasty. Diarrhoea was present in 68 per cent of patients in whom the vagotomy was truncal and in 31 per cent of those in whom it was proximal gastric. Matched groups of patients with truncal vagotomy with pyloroplasty and proximal gastric vagotomy without cholecystectomy were also compared. The possible mechanisms of this diarrhoea following combined vagotomy and cholecystectomy have been discussed.
