Hepatopancreatoduodenectomy for anastomotic recurrence from residual cholangiocarcinoma: report of a case

Surgical management of carcinoma in situ at ductal resection margins in patients with extrahepatic cholangiocarcinoma

Recent advances in dimensional imaging, surgical technique, and perioperative patient care have resulted in increased rates of complete resection with histopathologically negative margins and improved surgical outcomes in patients with extrahepatic cholangiocarcinoma. However, achieving cancer-free resection margins at ductal stumps in surgery for this disease remains challenging because of longitudinal extension, which is one of the hallmarks of extrahepatic cholangiocarcinoma. When the ductal resection margins are shown to be positive on examination of frozen sections, discrimination between carcinoma in situ and invasive carcinoma is clinically important because residual carcinoma in situ may lead to late local recurrence whereas residual invasive carcinoma is associated with early local recurrence. Residual invasive carcinoma at the ductal margins should be avoided whenever technically feasible. Residual "carcinoma in situ" at the ductal margins appears to be allowed in resection for the advanced disease because it has less effect on survival than other adverse prognostic factors (pN1 and/ or pM1). However, in surgery for early-stage (pTis-2N0M0) extrahepatic cholangiocarcinoma, residual carcinoma in situ at the ductal margins may have an adverse effect on long-term survival, so should be avoided whenever possible. In this review, we focus on the histopathological term "carcinoma in situ," the biological behavior of residual carcinoma in situ at ductal resection margins, intraoperative histological examination of the ductal resection margins, outcome of additional resection for positive ductal margins, and adjuvant therapy for patients with positive margins.

Long-term survival case of a recurrent colon cancer owing to successful resection of a tumor at hepaticojejunostomy: report of a case

With advances in surgical procedures and perioperative management, hepato-biliary-pancreatic surgery, including hepatectomy and pancreaticoduodenectomy, has been employed for recurrent colon cancer. However, no report has described a case of major hepatectomy with the combined resection of hepaticojejunostomy following pancreaticoduodenectomy for locoregionally recurrent colon cancer. Here, such a case is reported. The patient, a 37-year-old woman, had undergone pancreaticoduodenectomy for lymph node recurrence along the extrahepatic bile duct from cecal cancer. Thirteen months later, a biliary stricture was found at the hepaticojejunostomy site and right hepatectomy was performed. The resected specimen showed a papillary tumor at the hepaticojejunostomy. Based on its histological features, the pathogenesis of this tumor was considered to be intramural recurrence via lymphatic vessels. Although she underwent resection of a lymph node recurrence at her mesentery 12 months later, she has remained well thereafter, without any sign of further recurrence during 5 years of follow-up after hepatectomy.

Hepatopancreatoduodenectomy for local recurrence of cholangiocarcinoma after excision of a type IV-A congenital choledochal cyst: a case report

Surgical resection is the only curative treatment for biliary tract cancer (BTC); however, the recurrence rate remains high even after curative resection. There are limited data regarding the effectiveness of surgical resection for recurrent BTC. We report the favorable survival outcome of a patient who underwent a hepatopancreatoduodenectomy for local recurrence of cholangiocarcinoma after excision of a type IV-A congenital choledochal cyst. The patient, a 25-year-old woman, had undergone excision of a type IV-A congenital choledochal cyst with hepaticojejunostomy. The resected specimen revealed an early cholangiocarcinoma. The local recurrence at the site of anastomosis was detected 4 years and 4 months after surgery. We performed a left trisectionectomy with caudate lobectomy combined with hepatic artery and portal vein resections and a pancreaticoduodenectomy. Histological examination revealed a moderately differentiated adenocarcinoma, and the final diagnosis was recurrence of cholangiocarcinoma. There are a few reports of extensive resection for recurrence of BTC; however, aggressive surgery is possible and may offer favorable survival in selected patients.
