En bloc right hemicolectomy and pancreaticoduodenectomy with superior mesenteric vein resection for advanced right-sided colon cancer.

A 58-year-old female was referred to our hospital with a diagnosis of bowel obstruction due to advanced transverse colon cancer invading the duodenum. Two months after the emergency bypass operation for the bowel obstruction, we performed an en bloc right hemicolectomy with pancreaticoduodenectomy (RHCPD) with a curative intent. During the operation, we could not dissect the tumor from the superior mesenteric vein, so we performed a segmental cylindrical resection of the superior mesenteric vein and its reconstruction. The post-operative course was uneventful, and after a 34-day hospital stay the patient returned to daily life. A histologic examination also revealed a well-differentiated tubular adenocarcinoma invading the duodenum. All the surgical margins were negative and lymph node metastasis was not found. There were no signs of recurrence for 8 months after the operation. Complete resection clearly influences survival time of patients, and surgeons should not hesitate to perform RHCPD.
