Impact of radiotherapy on palliative gastroenterostomy in pancreatic cancer.
The previously unaddressed impact of radiotherapy and vagotomy on palliative gastroenterostomy (GE) in patients with unresectable pancreatic cancer was studied. Sixty-eight patients were retrospectively evaluated. A higher overall incidence of complications was found in the group (N = 44) undergoing irradiation as well as gastroenterostomy compared to a group undergoing gastroenterostomy alone. The increased complications were due to 16 episodes of bleeding among the irradiated patients. Rates of obstructive complications were similar for both groups (20%). Rates of bleeding were highest among patients undergoing prophylactic GE and irradiation compared to those receiving GE alone. Vagotomy in 12 patients who were irradiated did not appear to protect against bleeding. We found the irradiated prophylactic GE to provide poor palliation in patients with unresectable pancreatic cancer and recommend it not be performed if radiotherapy is to be used for attempt in local control of unresectable pancreatic cancer.
