Anyone who knows anything about weight loss surgery should know that it is a surgical procedure performed using laparoscopic technology. Generally, laparoscopic surgery requires four holes to be opened in the stomach, and although the post-operative scars are less obvious compared to traditional open surgery, some young women are still concerned about it. The single-port laparoscopic technique, which is performed through an opening in the human belly button, does not leave a scar after surgery. However, this “black technology” was once met with skepticism. In the early days of laparoscopic technology, many people thought that a small opening would not allow them to see the inside of the body clearly, and that the operation would only be more unsafe. The four-hole laparoscopic technique was criticized, not to mention the single-hole laparoscopic surgery. Is laparoscopic surgery really that dangerous? In fact, with the 4-fold magnification of the laparoscope, the surgeon not only has a clear understanding of the body’s environment, but also has a better understanding of the details of the surgery. While traditional open surgery is not a major problem in terms of visualization, the large opening also carries risks such as high bleeding and wound sensation. Single-port laparoscopic surgery summarizes the strengths and weaknesses of various surgical procedures, building on their strengths and avoiding their weaknesses. The small size of the incision also means that bleeding is effectively controlled and wound infection is less likely to occur, and there is no scarring for the aesthetic bariatric patient. It is worth mentioning that the technology associated with single-port bariatric surgery is complex, requiring precision instruments in addition to a high level of skill on the part of the surgeon in charge. In the field of bariatric surgery, China has just completed the initial introduction of development, and there are few bariatric surgeons, and those with experience and skills are very rare. Our surgeons have more than 10 years of experience and are able to carry out various procedures of bariatric surgery smoothly, and will obtain higher safety and results under the surgery of two doctors.
