Novel technique using a bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen’s space hernia

Introduction: Laparoscopic Roux-en-Y gastric bypass is a bariatric operation that is effective for long-term weight loss. Although rare, one serious complication is an internal hernia through Petersen’s space, which may result in bowel strangulation. Although the incidence of internal hernia can be reduced through closing the Petersen’s defect, it does not eliminate the risk. This case describes a novel and reliable method to close Petersen’s defect. We report the case of a 30-year-old female who underwent a laparoscopic Roux-en-Y gastric bypass for the management of morbid obesity. Following her Roux-en-Y reconstruction, a prosthetic bioabsorbable mesh was placed in Petersen’s space and reinforced with fibrin glue to prevent internal herniation through Petersen’s defect. The use of a bioabsorbable mesh in Petersen’s space is a novel and easy technique that could be used to reduce the incidence of an internal hernia through Petersen’s defect.
