Role of intraoperative enteroscopy in the management of obscure gastointestinal bleeding at the time of video-capsule endoscopy.

Background: This study aimed at evaluating the role of intraoperative enteroscopy (IOE) for the management of obscure gastrointestinal (GI) bleeding in patients who had been preoperatively explored by video-capsule endoscopy (VCE).

Methods: Eighteen patients who underwent IOE for obscure GI bleeding were prospectively recorded between November 2000 and January 2007. The bleeding site was preoperatively localized by VCE in the small bowel in 15 patients, but the origin of bleeding remained unknown in 3 patients.

Small bowel diverticulosis complicated by perforated jejunal diverticula: conservative and/or surgical management?

Small Bowel Diverticulosis (SBD) is rare and defined by the presence of multiple acquired mucosal herniations on the layer of the duodenal or jejunoileal loop. Usually asymptomatic, SBD is revealed by complications in 5 to 10% of cases. We report two cases of SBD complicated by perforated diverticula.

Liver hanging maneuver: an anatomic and clinical review.

Background: Liver hanging maneuver (LHM) allows to hang the liver during right hepatectomies without primary liver mobilization. The avascular plane used in this technique has been poorly described in the anatomical literature, and intraoperative bleeding because of hepatic vein injuries has been reported.

Data Sources: Major clinical and anatomic articles focusing on the retrohepatic portion of the inferior vena cava (IVC) and the LHM were reviewed.

Endoscopic management of a large choledochocele associated with choledocholithiasis.

Choledochocele or type III choledochal cyst is a very rare lesion, defined as a cystic dilatation of the distal common bile duct protruding into the duodenal lumen. Abdominal pain, biliary disorders, and acute pancreatitis are frequently observed but malignant degeneration is rare. A 70-year-old man had a history of epigastralgia associated with abnormal liver function tests suggesting gallstones.

Type, density, and location of immune cells within human colorectal tumors predict clinical outcome.

The role of the adaptive immune response in controlling the growth and recurrence of human tumors has been controversial. We characterized the tumor-infiltrating immune cells in large cohorts of human colorectal cancers by gene expression profiling and in situ immunohistochemical staining. Collectively, the immunological data (the type, density, and location of immune cells within the tumor samples) were found to be a better predictor of patient survival than the histopathological methods currently used to stage colorectal cancer.
