Gallbladder cancer (GBC) often invades the hepatic hilum and even small tumors can cause obstructive jaundice. Operative intervention for GBC with obstructive jaundice is sometimes not recommended because it is associated with a poor prognosis. However, the extended procedure is recommended for patients with hilar cholangiocarcinoma (HC). We therefore compared the postoperative survival of patients with GBC invading the hepatic hilum with that with HC. Between 1998 and 2008, 27 patients with GBC invasion of the hepatic hilum (hGBC) and 124 with HC underwent surgical resection with curative intent in the Department of Surgical Oncology, Hokkaido University Graduate School of Medicine. This study included patients with GBC without peritoneal dissemination and liver or para-aortic lymph node metastasis. Extended right hemihepatectomy and extrahepatic bile duct resection comprise the treatment of choice for GBC with hilar invasion (hGBC). We aimed to achieve R0 outcomes by aggressive vascular resection and/or concomitant resection of directly invaded organs around the GBC along with extended right hemihepatectomy. We analyzed 27 patients with hGBC (age 58–83 years; median 71 years; male:female 13:14) and 124 with HC (age 45–80 years; median 69 years; male:female 94:30). The 3- and 5-year survival rates of 43 and 24% for hGBC and 58 and 38% for HC, respectively, did not differ significantly (p = 0.14). Preoperative obstructive jaundice was a complication in 22 (81%) and 95 (77%) patients with hGBC and HC, respectively. The 5-year survival rates were 40 and 36%, respectively, which did not differ significantly (p = 0.61). The 5-year survival rates after extended right hemihepatectomy to resect the tumor with curative intent were 34 and 34% for hGBC and HC, which did not differ significantly (p = 0.14). The prognosis after curative resection of GBC with hilar invasion is similar to that of HC in selected patients. Aggressive surgery for advanced GBC with hilar invasion might increase survival rates.

It is important to predict the development of clinically relevant pancreatic fistula (grade B/C) in the early period after pancreaticoduodenectomy (PD). This study has been carried out as a project study of the Japanese Society of Hepato-Biliary-Pancreatic Surgery (JSHPBS) to evaluate the predictive factors associated with clinically relevant pancreatic fistula (grade B/C).The data of 1,239 patients from 11 medical institutions who had undergone PD between July 2005 and June 2009 were retrospectively analyzed to review patient characteristics and perioperative and postoperative parameters.A drain amylase level4,000 IU/L on postoperative day (POD) 1 was proposed as the cut-off level to predict clinical relevant pancreatic fistula by the receiver operating characteristic (ROC) curve. The sensitivity, specificity, and accuracy of this cut-off level were 62.2, 89.0, and 84.8%, respectively. A multivariate logistic regression analysis revealed that male [odds ratio (OR) 1.7, P = 0.039], intraoperative bleeding1,000 ml (OR 2.5, P = 0.001), soft pancreas (OR 2.7, P = 0.001), and drain amylase level on POD 14,000 IU/L (OR 8.6, P 0.001) were the significant predictive factors for clinical pancreatic fistula.The four predictive risk factors identified here can provide useful information useful for tailoring postoperative management of clinically relevant pancreatic fistula (grade B/C).
