Laparoscopic resection of gastric schwannoma: A case report.

Introduction: Gastric schwannomas are an extremely rare presentation of mesenchymal tumors originating from Schwann cells, accounting for 0.2% of all gastric tumors. Patients are usually asymptomatic, so these tumors are frequently detected incidentally.

[Jejunal diverticulitis causing an acute abdomen].

Jejunal diverticulosis is a rare acquired-disease which courses asymptomatic in most cases. In spite of the fact that there are some publications of this entity in pediatric patients, most symptomatic cases have been found in adults. Reported herein is the case of a patient that presented to the emergency room with signs and symptoms suggestive of an acute abdomen.

[Jejunal angiodysplasia as a cause of obscure gastrointestinal bleeding].

Background: Obscure gastrointestinal bleeding secondary to jejunal angiodysplasia is uncommon. Diagnostic approach is difficult and represents a challenge for the surgeon because of the inaccessibility of the small bowel for evaluation. When the diagnostic work-up has been completed and the bleeding source has not been found, it is mandatory to perform a surgical exploration with transoperative enteroscopy in order to locate the source of the hemorrhage and for further treatment.

Major hepatic resection for hilar cholangiocarcinoma: analysis of 46 patients.

Hypothesis: Major hepatectomy, bile duct resection, and regional lymphadenectomy for hilar cholangiocarcinoma are associated with actual long-term (>5 years) survival.

Design: Retrospective outcome study.

Setting: Single tertiary referral institution.
