title: Feasibility of en-bloc wedge resection of the pancreas and/or the duodenum as an alternative to pancreatoduodenectomy for advanced gallbladder cancer.
abstract: Pancreatoduodenectomy has been described as a possible treatment for gallbladder cancer that presents with evidence of direct invasion to the pancreas and/or the duodenum. This procedure does, however, carry a significantly higher morbidity and mortality if performed with a hepatectomy. An alternative procedure, therefore, of wedge resection of the invaded organ(s) was investigated in this study. On recognition of infiltration of the tumor into the pancreas and/or the duodenum, an en-bloc wedge resection of the organ(s) combined with the original tumor was the intended procedure. However, a pancreatoduodenectomy was performed if the tumor was not resectable by an attempted wedge resection. Operative and long-term outcomes were compared between patients who underwent wedge resection (n = 9) and pancreatoduodenectomy (n = 8). One patient in each group was incorrectly diagnosed preoperatively as having cancer invasion, as opposed to inflammatory changes, as recognized by subsequent histology. All tumors were excised with tumor-free pancreatic and duodenal margins. Postoperative complications occurred in one patient with wedge resection and four with pancreatoduodenectomy. One in-hospital death occurred in each group; one patient died with wedge resection of sepsis and one patient with pancreatoduodenectomy died of a pancreatic leak. No local recurrence occurred in either group. There was no difference in cumulative survival rates between the groups. Wedge resection was considered to be a feasible surgical procedure, in terms of morbidity, respectability, and long-term outcome.
