High resectability of colorectal liver metastases with aggressive chemotherapy in the era of molecular target-based agents.

Background/aims: Advances in chemotherapy have expanded the resectability of colorectal liver (CRC) metastases. We studied treatment results in CRC patients with liver metastases in the era of molecular target-based agents.

Methodology: Based on data collected retrospectively, we analyzed the demographics, operative and pathological outcomes, and adjuvant chemotherapy, of 91 consecutive CRC patients with liver metastases treated between January, 2008 and June, 2010.

Is drip infusion cholecystocholangiography (DIC) an acceptable modality at cholecystectomy for cholecystolithiasis, considering the frequency of bile duct maljunction and intraoperative bile duct injury?

Background/purpose: Knowledge of the configuration of the extrahepatic bile duct is indispensable to avoid bile duct injury during cholecystectomy. Various methods of examining the biliary tract have been developed; however, the most appropriate preoperative diagnostic modality at cholecystectomy for cholecystolithiasis has not yet been reported. Considering the frequency of bile duct maljunction (BDM) and operative bile duct injury, in addition to the cost and invasiveness of the various examination methods, we evaluated the usefulness of drip infusion cholecystocholangiography (DIC) as the optimal method of examination at cholecystectomy for cholecystolithiasis.
