Role of gastroenterostomy in the palliative surgical treatment of pancreatic cancer

The records of 72 consecutive patients with unresectable pancreatic cancer treated between 1974 and 1986 were evaluated to determine whether gastroenterostomy should be performed on a routine basis at initial intervention or on a therapeutic basis. Fourteen patients underwent an explorative laparotomy, 41 patients underwent biliary bypass, and 17 patients required biliary bypass and therapeutic gastroenterostomy at initial laparotomy. The mortality and morbidity rates in this last group were 18 and 59%, respectively. The most common complication was delayed gastric emptying (29%). Of the 37% of patients who required gastroenterostomy after initial biliary bypass, the mortality rate was 50% and delayed gastric emptying occurred in 57%. The mean survival after biliary bypass was 9.4 months while survival after therapeutic gastroenterostomy averaged 4.2 months. These findings suggest that gastroenterostomy should be performed on a prophylactic basis at initial intervention, unless a limited survival is expected.
