A prospective, randomized-controlled pilot study comparing closed suction versus negative pressure drains for panniculectomy patients

Panniculectomy following massive weight loss has a reported complication rate of 31-76% with seroma formation 14-28%.(1) The authors performed a prospective, randomized study comparing seroma formation with standard bulb drains (BD) versus internal drains attached to continuous negative pressure (NP) following panniculectomy. NP drains were placed on continuous powered-suction at -125mmHg via Renasys*GO drain device (Smith&Nephew, Memphis,TN).
