For fat friends, when the BMI reaches 27 or more, by themselves can not be reduced to the normal level of 22, some fat friends will choose to reduce weight through surgery, may not know what is a single-hole surgery to reduce weight? What is the difference with the previous traditional laparoscopic comparison? When it comes to minimally invasive laparoscopic weight loss surgery, fat people are certainly not unfamiliar: 3-4 small holes in the belly, the gastrointestinal tract will be reorganized, so that fat people eat less and absorb less after surgery, so as to achieve weight loss and effective weight control, to avoid the huge scars left by open surgery. However, since November 2008, surgeons have pioneered the “transumbilical scarless gastric bypass” based on this procedure, ushering in the scarless era of bariatric surgery. The new single-port bariatric surgery is a sleeve gastric surgery or gastric bypass that is performed through the navel as an entrance into the abdominal cavity, so that no scars are evident after surgery. What are the advantages of the two types of surgery? With single-port bariatric surgery, only a small incision in the belly button is required. Laparoscopic surgery, which requires 3-5 holes in the abdomen. In comparison, single-port surgery has more significant advantages! The advantage of single-port laparoscopic surgery is that there is no scar for the patient after surgery and the weight loss effect is good, but single-port scarless surgery is difficult and requires a high level of skill and is a test for the surgeon, so it requires a high level of personal medical skills. All those who want to do single hole weight reduction surgery must choose a good hospital.
