Imaging appearance on CT post laparoscopic Roux-en-Y gastric bypass using bioabsorbable prosthesis with fibrin glue fixation to prevent a Petersen's space hernia.

Imaging post bariatric surgery is becoming more common over the past decade due to increasing incidence of obesity in the population and subsequent treatment. In recent years, the use of topical haemostatic agents and bioabsorbable prostheses has increased leading to higher likelihood of encountering these agents on post-operative imaging. Imaging in the post-operative period is occasionally performed to assess for complications such as obstruction, leak and abscess formation.

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.

Background: Laparoscopic sleeve gastrectomy (SG) is gaining popularity as a revision option after failed laparoscopic adjustable gastric banding (LAGB). Data have shown that single stage revisions may be associated with a higher complication rate. A histologic basis for this observation has not been studied.
