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.
抽脂术已被用于身体各部位，以去除大量皮下脂肪。钝性技术可形成多个小（4至6毫米）通道，并通过抽吸去除脂肪，对覆盖的皮肤、支撑间隔、血管或神经干扰极小。腹部抽脂术已成功开展数十年，通过锐性剥离去除大量皮肤和皮下脂肪。腹部抽脂术从剑突至耻骨、向外至髂嵴水平进行潜行分离，再辅以抽吸技术，在某些情况下会导致慢性血清肿形成，多次抽吸也无法缓解。这些血清肿的愈合和收缩会导致覆盖皮肤变形，因为皮肤会起皱并向内牵拉。这会形成一个由胶原片衬里但无上皮细胞的皮下假囊肿。我们报告了9例出现这种现象的患者。我们建议，在最大规模的切除手术中，在抽吸和后续切除之间至少等待6周，以确保安全性。
