No scars after surgery? Is it a fantasy, or a wild advertisement from a charlatan doctor? This is what most people think when they first hear the words “scarless surgery”. However, the advancement of technology has led to “scarless surgery” being introduced to the operating table for the benefit of patients. There are three main types of scarless surgery 1, single-hole laparoscopy through the umbilicus: there is only one incision, the incision is located in the navel, and the scar will be plastic sutured into the navel after surgery to achieve the purpose of minimally invasive and cosmetic. 2, natural cavity endoscopic surgery: through the patient’s natural cavity, such as through the mouth, anus or vagina into the abdominal cavity, and then use the curvable endoscope to complete the surgery. 3.Transcatheter robotic surgery: Under the guidance of X-ray or CT, a bendable robot is placed through the patient’s blood vessels, usually the femoral artery, and after reaching the designated location, the laser or radiofrequency is used to destroy the lesion and achieve the purpose of surgery. At present, because the techniques and equipment for natural lumen surgery and transvascular robotic surgery are not fully mature, the main application that has been able to be used in clinical practice is still transumbilical single-port laparoscopic surgery. As mentioned earlier, the principle of transumbilical single-port laparoscopy is to enter the abdominal cavity through the belly button. Can this approach accomplish intra-abdominal surgery and what are the surgical results and safety? It is a matter of concern for the majority of patients. And in recent years, after continuous exploration by laparoscopic surgeons, single-port laparoscopy has been able to perform all the surgeries that laparoscopy can perform, including single-port laparoscopic radical cystectomy + enlarged lymph node dissection, single-port laparoscopic radical nephrectomy + removal of inferior vena cava tumor embolus and other ultra-high difficulty and complexity surgeries. Since the endoscope used in uniportal laparoscopy is a bendable endoscope, to some extent, the view of uniportal laparoscopy is even better than that of traditional open surgery, allowing to see angles that cannot be seen in open surgery, such as the posterior aspect of the inferior vena cava or the posterior aspect of the prostate acinus. The result of this superior view is a much more precise surgery, which avoids unnecessary vascular damage and reduces surgical bleeding. In this regard, Dr. Liss and others in Switzerland, after a series of clinical trials, demonstrated that even for the most dangerous and complex of all urological procedures, which require the highest surgical skills for the removal of inferior vena cava aneurysms, there is no statistical difference in the safety, speed of surgery or postoperative recovery between single-port laparoscopic surgery and multi-port conventional laparoscopic surgery, and that single-port laparoscopic surgery was also slightly better than conventional laparoscopy in all indicators. Therefore, for physicians skilled in laparoscopic and single-port laparoscopic techniques, there is no significant difference between the two. Single-port laparoscopy began to be used in clinical practice in China in 2008 and in 2009 for all urological procedures. However, because it requires a longer learning curve and higher surgical skills compared to traditional laparoscopy, it is currently being performed in only a few large medical centers in China. It is mainly located in cities such as Beijing, Shanghai, and Guangzhou. Few reports are available in the central and western regions.
