We report a case of gallbladder hernia into the lesser sac through the foramen of Winslow. The patient was a 90-year-old woman, admitted to hospital with obstructive jaundice. Computed tomography (CT) showed a left-deviated and remarkably enlarged gallbladder dragging the liver, and a dilated intrahepatic bile duct. The deviated gallbladder was thought to compress the common bile duct, causing the obstruction. Laparoscopic examination revealed gallbladder herniation into the lesser sac without a floating gallbladder; thus, we performed laparoscopic cholecystectomy. Herniation of the gallbladder is the rarest of all internal hernias and most reported cases have involved a floating gallbladder. The case we report here is therefore considered especially unusual.

198 Background: Despite proven benefit of adjuvant chemotherapy in pancreatic cancer patients, earlyrecurrenceoccursinaconsiderablerate. Therefore, outcomeprediction in these patients remains a challenge. The aim of this study was to determine whether Glasgow Prognostic Score (GPS) and CA19-9 could predict early recurrence in patients undergoing adjuvant chemotherapy after surgery. Methods: 67 pancreatic ductal adenocarcinoma (PDAC) patients underwent curative resection and received adjuvant chemotherapy with gemcitabine after surgery at Kanagawa Cancer Center between 2007 and 2012.The GPS, CA19-9(measured prior to adjuvant therapy) and other clinicopathological factors were retrospectively reviewed. The GPS was calculated from CRP and albumin as follows: patients with both an elevated CRP level (>0.5mg/dl) and hypoalbuminemia (<3.5g/dl) were allocated a score of 2, patients with only one of these biochemical abnormalities were allocated a score of 1, and patients with neither of these abnormalities were ...

194 Background: S100A10 is a member of the S100 family of proteins containing two EF-hand calcium-binding motifs. They regulate a number of cellular processes such as cell cycle progression and differentiation. The objective of this study is to clarify the clinical significance of S100A10 in patients with pancreatic cancer. Methods: A total of 48 pancreatic adenocarcinoma tissues from patients underwent curative surgery were enrolled. Double 2-mm core tissue microarrays were made from paraffin-embedded pancreatic cancer samples and examined by immunohistochemistry for S100A10 protein. The correlations of expression level and clinicopathological outcome including recurrence free survival (DFS) were analyzed. Results: Expression level of the S100A10 protein in cytoplasm was categorized as overexpressed or others according to the baseline expression level in normal pancreatic duct. Overexpression of S100A10 protein was found in 9 of 48 (16.7%) cases. Statistical analysis revealed that related factor was dist...
