Outcome of palliative biliary and gastric bypass surgery for pancreatic head carcinoma in 126 patients

Abstract

Background. Recent reports of decreased morbidity and mortality following palliative surgery for patients with irresectable pancreatic head carcinoma prompted a review of the results in 126 patients (median age 64 (range 39-90)years) who had undergone palliative biliary and gastric bypass surgery. Methods. The indication for surgical palliation was the finding of an irresectable tumour at laparotomy (n = 44), failure of endoscopic treatment (n = 43), clinical symptoms of gastric outlet obstruction (n = 28) and miscellaneous (n = 11). Biliary and gastric bypass was performed in 118 patients, biliary bypass alone in six and gastrojejunostomy alone in two. The indication for gastrojejunostomy was symptoms in 28 patients (23 per cent) and prophylaxis in 92 patients (77 per cent). Results. Postoperative local complications occurred in 17 per cent of patients, general complications in 10 per cent and delayed gastric emptying in 14 per cent of patients. The 30-day mortality rate was 1 per cent and overall hospital mortality rate 2 per cent. Median hospital stay was 17 (range 5-80) days. Median overall postoperative survival was 190 (range 14-830) days. Late obstructive gastrointestinal symptoms occurred in 14 patients (11 per cent) after a median of 141 (range 21-356) days. Conclusion. Roux-en-Y hepaticojejunostomy combined with gastrojejunostomy offers effective palliation for irresectable pancreatic head cancer and can be performed with low mortality and acceptable morbidity rates.
