The success of the first laparoscopic surgery in France in 1987 ushered in a new era of minimally invasive surgery. Laparoscopic surgery has the advantages of small trauma and fast recovery, and was quickly accepted by surgeons and patients, and in less than 10 years has rapidly become popular around the world, from the initial simple cholecystectomy to the radical resection of stomach, intestinal tumors and even pancreatic tumors, replacing the traditional caesarean section as the preferred method for many abdominal diseases. The following is a brief introduction to the development of laparoscopy and laparoscopy in general surgery: a. What is laparoscopic surgery all about? Laparoscopic surgery, also known as “minimally invasive” surgery, represents the direction of surgical development. When performing abdominal surgery without a large incision, only 2-4 small 0.5-1.0 cm keyhole-like holes with a puncture needle inserted into the TV camera system, connected to the laparoscope and three trocar needles, the doctor can monitor through the fluoroscope, with high-frequency electric knife and other instruments to perform surgery, and convenient and fast. Second, what are the advantages of laparoscopic surgery? Laparoscopic surgery has the incomparable advantages of ordinary surgery, mainly small trauma, good results, fast recovery and less pain. Laparoscopic surgery does not require a large incision, and can be fixed with a band-aid for 2-3 days after surgery, usually without sutures, and without obvious scars after surgery, which is especially suitable for women’s beauty needs. Due to the use of advanced camera system, the abdominal organs are clearly visible during surgery, which makes it easy to operate and does not cause damage to other organs or produce adhesions, plus the use of high-frequency electric knife surgery bleeding very little, so there are few postoperative complications, light pain, generally do not need to use painkillers. Because of the light interference with other organs, the gastrointestinal function recovers quickly, and the patient can go to the ground on the day of surgery, be discharged from the hospital in 3-5 days, and resume work in 7-15 days, and there are no complications such as intestinal adhesions after surgery. Third, what are the indications for laparoscopic surgery? What diseases can be treated? At present, the main diseases treated by laparoscopy include laparoscopic cholecystectomy, common bile duct exploration, appendectomy, pediatric hernia ligation, adult hernia repair, hepatic cyst (abscess) opening and drainage, intestinal adhesion release, laparoscopic exploration of acute abdomen and abdominal injury (gastric perforation, liver and spleen rupture repair), splenectomy, pancreatic tumor removal, and radical resection of gastric cancer, colon cancer and rectal cancer. There are also surgical treatment for diabetes and surgical treatment for weight reduction of pathological obesity. IV. What is the difference between laparoscopic poke and surgical incision? Some people are not convinced about laparoscopic surgery, thinking that the sum of the length of 2-4 laparoscopic surgery poke holes is the same as the length of open incision. It seems that laparoscopy is superfluous. In fact, from an arithmetic point of view alone, the sum of laparoscopic poke holes is also smaller than any abdominal incision, and this is not the main difference between the two. The main difference between the two is that: 1, laparoscopic surgery poke hole is to expand into the abdominal cavity with instruments, the integrity of the abdominal wall is basically preserved. In contrast, open incision is by way of incision, there is abdominal wall muscle and corresponding vascular nerve damage, postoperative skin around the incision will appear numb, abdominal wall muscle scarring and thus become weak, there is a risk of abdominal wall incision hernia. 2, laparoscopic abdominal wall poke holes are small (ranging from 3-10mm), scattered and concealed, and do not affect the aesthetics after healing. And we often see that the surgical incision forms a centipede-like proliferative scar. 3, traditional open incision infection or fat liquefaction and incision splitting has been an unavoidable problem. And laparoscopic surgery is the best way to solve this problem. In short, laparoscopy is a small incision and large surgery, and open surgery is a large incision and small surgery. Laparoscopic surgery is an exemplary combination of modern high technology and traditional medicine, which follows the treatment principles of traditional surgery and completes traditional surgery with minimally invasive surgical skills, representing a new trend in the development of minimal trauma surgery with broad development prospects.
