At present, minimally invasive surgery, represented by laparoscopy, is increasingly used in bariatric surgery. With the improvement of minimally invasive technology and the continuous improvement of surgical instruments, minimizing surgical trauma and improving the cosmetic effect of surgical wounds have become the common goal of surgeons and patients. In order to implement the concept of minimally invasive and to improve the advantages of laparoscopy, single-port laparoscopic surgery was born. Is single-port laparoscopy, the legendary minimally invasive surgery that leaves almost no scars, really that amazing? The benefits of single-port laparoscopic surgery compared to traditional laparoscopic abdominal minimally invasive surgery are mainly on the patient side, that is, no scar cosmetic, small incision hidden in the umbilicus, not carefully look to identify. The small incision is hidden in the umbilicus and cannot be recognized without close examination. It can be “faked”, so it is meaningful and beneficial for those who are particularly demanding, and has more prominent characteristics such as minimally invasive, safe, aesthetic, and less pain after surgery. Due to the small trauma, single-port laparoscopic surgery is less painful than standard laparoscopic surgery, which can reduce the amount of intraoperative and postoperative anesthesia and analgesic drugs. Patients recover quickly after surgery, and hospitalization costs are correspondingly reduced. For patients, if your hospital offers single-port laparoscopy, you can talk to your doctor about whether you are a good candidate for single-port laparoscopy; the final decision is up to your doctor. Even if your surgeon agrees that single-port laparoscopy is possible, you should be aware of the possibility of adding an intraoperative incision to convert to conventional laparoscopy or even to open surgery. For the surgeon, whether single-port, multi-port or open, it is only the surgical approach; the purpose and principles of surgery remain the same. Whether single-port laparoscopy can be performed depends on the surgeon’s ability and skill, and also requires appropriate instruments and equipment. It is the surgeon’s responsibility to fully assess the patient’s condition and his or her own skills to choose the surgical approach that is most beneficial to the patient.
