Requirement and postoperative outcomes of abdominal panniculectomy alone or in combination with other procedures in a bariatric surgery unit

BackgroundA high percentage of patients present with redundant skin folds after bariatric surgery. This study aims to quantify the need for panniculectomy after open bariatric surgery and to analyze the postoperative outcomes.MethodsA retrospective cohort study was performed. The patients were divided into 2 groups: group DLP, patients who underwent an abdominal panniculectomy alone and group DLP+, those who underwent panniculectomy in association with another surgical procedure.ResultsFour hundred forty-six patients underwent open bariatric surgery and 130 patients (29%) subsequently required an abdominal dermolipectomy. Seventy-six percent presented also incisional hernia and 8% presented cholelithiasis. Forty-six percent of patients presented postoperative complications: wound seroma/infection (21%), wound dehiscence due to skin necrosis (13%), and hemorrhage/hematoma (10%) were the most frequent. There were no major complications or mortality. DLP+ was not associated with an increase in complications.ConclusionsAfter open bariatric surgery, an abdominal panniculectomy is often required. This procedure has a high postoperative morbidity in these patients, although complications are usually mild. There is not an increase in the rate of complications when panniculectomy is associated with other procedures.
