Wide topical negative pressure wound dressing treatment for patients undergoing abdominal dermolipectomy following massive weight loss.

Postbariatric plastic surgery is considered to be a high-risk procedure, which entails such frequent minor complications as postoperative seroma, bleeding and wound dehiscence. These occur with a high incidence, especially, following postbariatric abdominal dermolipectomy. In order to reduce these complication rates, a new type of dressing with wide abdominal topical negative pressure (TNP) application was applied. We performed abdominal dermolipectomy in 23 obese patients. The average body mass index was 32.8 kg/m(2), and the median age of the patients was 42.9 years. Ten patients received conventional standard dressings (control group I), whereas the other 13 patients received a wide TNP dressing including the ventral and lateral trunk (negative pressure group II). Postoperative exudate volumes were collected, tallied and documented for each group separately until all drains could be removed. The conventionally treated control group (I) showed a significantly higher postoperative secretion volume compared with the negative pressure group (II). In addition, the average time to postoperative final drain removal was significantly lower in the negative pressure group (II) compared with the control group (I). The results indicate that widely applied external TNP wound dressing on the ventral and lateral trunk following postbariatric abdominal dermolipectomy leads to a significant reduction in exudate formation, enables early drain removal and thus, decreases length of hospitalization.
