INTERNAL HERNIA FOLLOWING LAPAROSCOPIC ROUX-EN-Y GASTRIC BY-PASS: INDICATIVE FACTORS FOR EARLY REPAIR.

Background: Internal hernia (IH) following laparoscopic Roux-en-Y gastric bypass (LRYGB) is a major complication that challenges the surgeon due to its non-specific presentation and necessity of early repair. Delayed diagnosis and surgical intervention of IH might lead to increased morbidity of patients and impairments in their quality of life.

Objective: To evaluate the predictive factors for early diagnosis and surgical repair of IH after LRYGB.

FIXING JEJUNAL MANEUVER TO PREVENT PETERSEN HERNIA IN GASTRIC BYPASS.

Background: Among Roux-en-Y gastric bypass complications is the occurrence of intestinal obstruction by the appearance of internal hernias, which may occur in Petersen space or the opening in mesenteric enteroenteroanastomosis.

Aim: To evaluate the efficiency and safety in performing a fixing jejunal maneuver in the transverse mesocolon to prevent internal hernia formation in Petersen space.

Method: Two surgical points between the jejunum and the transverse mesocolon, being 5 cm and 10 cm from duodenojejunal angle are made.
