Effect of electrosurgical technique on wound healing and early complication rate following abdominal dermolipectomy.

Abstract

Thirty-eight patients with significant weight loss after vertical banded gastroplasty were studied prospectively while undergoing abdominal dermolipectomy to determine if the current intensity used during electrosurgical dissection influenced wound complication rates after this surgery. Patients were assigned randomly to one of two groups: (1) a HI group, in which the electrosurgical current intensity was set at a level that easily allowed coagulation of all vessels smaller than 0.5 mm in diameter or (2) a LO group, in which the current intensity was set at a much lower level that allowed dissection, but required that nearly all visible vessels be ligated separately. A standardized procedure was employed for all patients. The patients in the LO (N = 14) and HI (N = 24) groups were well matched for age, weight history, nutritional parameters, operative times, surgical blood loss, and postoperative hospital stay. The overall complication rates of 36% and 21%, and wound complication rates of 36% and 13% for the LO and HI groups, respectively, were not significantly different. These data indicate that using a relatively high electrosurgical current intensity for dissection during abdominal lipectomy does not result in a higher wound complication rate.
