Perirenal perivascular epithelioid cell tumor (PEComa).

A 52-year-old woman, who is a carrier of MLH-1 mutation (HNPCC-type Lynch syndrome) with a history of colon adenocarcinoma, was diagnosed with a 26 mm lobulated contrast-capturing mass located caudally of the pancreas tail, anteromedial of the spleen and medial of the splenic colon angle. She underwent an exploratory laparotomy with resection of the tumor. Initially, this mass was presumed to be metastasis in a patient with a history of colon adenocarcinoma.

A prospective, multicenter, observational study on quality of life after laparoscopic inguinal hernia repair with ProGrip laparoscopic, self-fixating mesh according to the European Registry for Abdominal Wall Hernias Quality of Life Instrument.

Background: There is an increasing interest in patient-reported outcome measurement to evaluate hernia operations. Several hernia-specific quality of life (QoL) scales have been proposed, but none are constructed for preoperative assessment.

Methods: The European Registry for Abdominal Wall Hernias (EuraHS) proposed the short, 9-question EuraHS-QoL instrument for assessment pre- and postoperatively.

A new device for sentinel node detection in laparoscopic colon resection.

Objective: To test the feasibility of using a newly developed device for laparoscopic lymphatic mapping of the colon by simultaneous and quantitative detection of both tissue coloration and radioactivity.

Methods: Four pigs were used in this study. In each animal, both blue dye and radioisotope injections were utilized.

Safe laparoscopic surgery in the elderly.

Background: The elderly are more prone to complications of surgery because of comorbidity, and they may benefit most from a minimally invasive approach. This study was intended to evaluate the safety of the use of a laparoscopic approach for emergency and elective surgery in elderly patients.

Methods: From January 2000 to June 2001, all patients over 75 years of age who underwent a procedure that began laparoscopically were included.

Contraceptive treatment after biliopancreatic diversion needs consensus.

Background: An important population of patients who undergo biliopancreatic diversion (BPD) are fertile women. A consensus is needed with regard to contraceptive therapy after BPD by evaluating the risks of pregnancy, the safety of oral contraception and the changes in fertility after this bariatric surgery.

Method: From May 1997 until May 1998, 40 women who underwent a BPD were included in a prospective study evaluating the hormone status preoperatively and postoperatively after 2 and 7 days, 3 and 6 months and 1 year.
