Aims: In surgery for perihilar cholangiocarcinoma (PHCC), it is still controversial as to whether additional resection of the bile duct is needed on biliary intraepithelial neoplasia-3 (BilIN-3) margin. Methods: Patients who underwent surgery for PHCC with curative intent between 2001 and 2015 were stratified by resection margin, and were analyzed comparing the clinical outcomes. Results: Of the 306 study participants, 217 patients had negative margins (R0), 18 patients had BilIN-3, and 71 patients had positive margins (R1). The median overall survival of each group was 36.0 months in R0 group, 41.0 months in BilIN-3 group, and 25.0 months in R1 group while overall survival rates at 5 years were 34.5% in the R0 group, 44.4% in the BilIN-3 group, and 21.0% in R1 group. The median disease-free survival was 15.0 months in R0 group, 16.5 months in BilIN-3 group, and 12.0 months in R1 group. In the BilIN-3 group who had recurrence, 8 out of 9 patients had locoregional recurrence. Conclusions: Even if the BilIN-3 group has the potential to transform into malignancy, the survival and recurrence outcomes were comparable with R0 group, which suggests no additional resection is needed when maximal bile duct margin is BilIN-3 during PHCC surgery.

Aims: Right anterior sectionectomy (RAS) for hepatic disease is technically difficult and performed infrequently, so there is an insufficient reports about this surgery. We describe here the clinicopathologic and oncologic outcomes of right anterior segmentectomy in 415 patients. Methods: Patients treated with RAS at department of hepato- biliary and pancreatic surgery, Asan Medical Center, Seoul, South Korea between January 2008 and December 2017 were retrospectively reviewed. Results: All patients underwent RAS with alternative Glissonean pedicle clamp and Kelly clamp-crushing method for liver transection. Mean operative time was 165 minutes and transection time was 28 minutes. The incidence of major morbidity (≥grade III) occurred in 28 cases(6.7%). Bile leakage occurred in 63 patients (15.1%) but no patient needed reopration(grade C). Post hepatectomy liver failure grade A occurred in 39 patients (9.4%), grade B occurred in 7 patients (1.7%) but there was no patient of PHLF grade C. There was no in-hospital mortality due to postoperative complication. The mean hospital stay was 13.3 days.The pathologic diagnosis were hepatocellular carcinoma (HCC; n=361, 87.0%), intrahepatic cholangiocarcionoma (IHCC; n=15, 3.6%), HCC and IHCC mixed type (n=17, 4.1%), colorectal cancer liver metastasis (n=12, 2.9%), and the other lesions (n=10, 2.4%). Mean tumor size was 3.8 cm. In hepatocellular carcinoma (HCC), 5 year overall survival(OS) rate was 78.3% and 10 year OS rate was 64.4%. Five year disease free survival(DFS) rate was 57.2%, 10 year DFS rate was 37.7%. Conclusions: RAS showed acceptable procedure-related morbidity, mortality and appropriate oncologic outcomes for HCC.
