Results of pancreaticojejunal end-to-side anastomosis using the invagination method without a pancreatic stenting tube.

Background/aims: Perioperative management of pancreaticoduodenectomy (PD) is a constant dilemma and challenging for gastrointestinal surgeons. Postoperative pancreatic fistula (POPF) and delayed gastric emptying (DGE) are of particular concern, and the onset of these conditions indicates a prolonged postoperative stay (POS). The procedure and postoperative outcomes of pancreaticojejunostomy performed at our hospital are reported.

Superior mesenteric vein thrombosis as a complication of acute appendicitis : report of a case.

Since superior mesenteric vein thrombosis (SMVT) is a relatively rare disease and shows no specific symptom, its diagnosis tends to be delayed. In this report, we present a patient in whom acute appendicitis was complicated by SMVT and portal vein thrombosis (PVT). A definitive diagnosis could be made by abdominal contrast-enhanced CT, and acute appendicitis was surgically treated.

The efficacy of intraoperative ultrasonography during laparoscopic cholecystectomy.

Background/aims: Intraoperative ultrasonography (IOUS) has been used to delineate anatomy during laparoscopic cholecystectomy (LapC) and screen for common bile duct stones (CBDS), however no consensus about its efficacy has been reached in Japan. In this study, we compared and evaluated the performance of intraoperative cholangiography(IOC) and IOUS during LapC.

Methodology: We evaluated 295 cases of cholecystolithiasis that underwent surgery from 2005- 2009 at our hospital.
