Extended extrahepatic bile duct resection to avoid performing pancreatoduodenectomy in patients with mid bile duct cancer.
OBJECTIVE
Since proximal-to-mid bile duct (BD) cancers often involve the proximal portion of the intrapancreatic BD, resection of the extrahepatic BD can result in a tumor-positive distal resection margin. It is essential that a surgical procedure is developed to obtain a tumor-free distal BD resection margin during extrahepatic BD resection, in which R0 resection can be achieved without performing pancreatoduodenectomy.


METHODS
Based on preparatory clinicopathological analyses, excavation of the proximal intrapancreatic BD was designed to resemble a 2- to 3-cm-long funnel. The surgical procedure was a combination of the usual extrahepatic BD resection and funnel-shaped excavation of the proximal intrapancreatic BD.


RESULTS
This unique procedure, called extended extrahepatic BD resection, was performed on 3 patients aged over 70 years with mid BD cancer. Deep intrapancreatic BD excavation per se required about 1 h. A tumor-free intrapancreatic BD resection margin was obtained in all 3 patients. Only minor complications occurred. Two patients are doing well without recurrence, at 20 and 14 months, respectively, and one is alive at 12 months with lymph node metastasis detected 1 month earlier.


CONCLUSIONS
By achieving R0 resection, this extended extrahepatic BD resection seems to benefit some proximal-to-mid BD cancer patients in whom pancreatoduodenectomy has a high operative risk.
