Subcutaneous pseudobursa secondary to suction and surgery

Abstract

Suction lipectomy has been used throughout the regions of the body to remove vast amounts of subcutaneous fat. The blunt technique allows for a multiplicity of small (4 to 6 mm) channels to be created and the fat removed by suction with little disturbance of the overlying skin, the supporting septa, vessels, or nerves. Abdominolipectomy has been successfully performed for decades, in which large amounts of skin and subcutaneous fat are removed by sharp dissection. The undermining involved in an adbominolipectomy extending from the xiphoid to pubis and laterally to the level of the iliac crest and then supplemented by the suction technique has led to the formation, in some cases, of chronic seromas not relieved by multiple aspirations. Healing and contractions of these seromas causes a deformity of the overlying skin, because it is puckered and drawn upon itself. This results in the formation of a subcutaneous pseudobursa lined by collagen sheets but no epithelial cells. We present 9 patients who have demonstrated this phenomenon. We suggest that in the largest resections, safety is best served by waiting a period of at least 6 weeks between suction and subsequent resection.
