Scarless Gastric Sleeve is a different technique of the Gastric Sleeve procedure,It is called SILS technique.
When a surgeon uses the SILS technique, it means they make one small incision in the belly button. This results in a surgery that is virtually scarless. Single-incision sleeve gastrectomy surgery generally involves less pain and little or no scarring. The actual operation is the same as it is during a typical sleeve gastrectomy.
The difference is just in the number of incisions made. Since there is no need to cut through the stomach muscle, recovery time is shorter. SILS is different from a typical laparoscopic gastric sleeve because in those operations our bariatric surgeons make 5 small incisions. Although these operations are also considered minimally invasive and the scars are quite small, SILS gives an even more advanced option, which includes an often unnoticeable, single scar on the belly button.
