Panniculectomy after bariatric surgical weight loss: Analysis of complications and modifiable risk factors

Introduction

Bariatric surgery results in massive weight loss, leaving many patients with redundant skin that can cause significant physical and psychosocial limitations. We sought to identify variables associated with postoperative complications and adjuncts associated with the mitigation of postoperative complications.

Methods

A retrospective review was performed of all post-bariatric surgery patients who underwent panniculectomy over a 10-year period.

Results

Total 706 patients included. Overall complication rate was 56%: dehiscence (24%), surgical site infection (22%), seroma (18%), and post-operative bleeding (5%). Return to operating room rate was 12%. Significant factors were: BMI >26 (p?<?0.01), fleur-de-lis panniculectomy (p?<?0.01), concomitant hernia repair (p?<?0.01). Multivariate regression analysis demonstrated ASA class >2 (OR 1.97, p?<?0.05) and incision type (OR 1.64, p?<?0.05) to be independent predictors of morbidity.

Conclusion

High morbidity for post-bariatric panniculectomy is primarily local wound complications. Potentially modifiable factors that increase the complication risk profile include higher BMI, higher ASA class, and the use of fleur-de-lis incision.
