Abstract
The number of patients after gastric bypass being referred to plastic surgery units for secondary plastic surgery procedures is increasing The characteristic abdominal deformity includes a draping apron of panniculus occasionally associated with previous transverse surgical scars in the upper abdomen Often a limited abdominoplasty of the low transverse type with limited undermining only up to the level of the umbilicus is performed in order not to compromise blood supply in the zone between the old transverse and the new transverse scarWe propose a new modified and safe surgical technique to perform a complete abdominoplasty with wide undermining up to the xiphoid process in patients with preexisting transverse subcostal scars after gastric bypass surgery by selectively dissecting and preserving one to three periumbilical abdominal wall perforator vessels to secure flap blood supply Vessel tunnelling through the rectus sheath and muscle and ligation of the cephalad branch of the perforator provide sufficient flap mobility without perforator tension or traction Flap undermining is performed around these perforator vessels To match dissected flap perforators with bloodflow we performed postoperative colorflow duplex scanningWe conclude from our experience that with this perforatorsparing abdominoplasty technique safe and complete abdominoplasty can be performed with no additional risk of complications and that a good cosmetic result can be achieved in patients after open gastric bypass surgery
