A laparoscope is an instrument with a miniature camera. Minimally invasive laparoscopy is surgery performed with a laparoscope and its associated instruments: a cold light source is used to provide illumination, a laparoscopic lens (1 cm in diameter) is inserted into the abdominal cavity, and the images captured by the laparoscopic lens are transmitted via optical fibers to a back-end signal processing system and displayed in real time on a special monitor. The surgeon then analyzes the patient’s condition by using images of the patient’s organs from different angles displayed on the monitor screen and performs the surgery with special laparoscopic instruments. Laparoscopic surgery is mostly performed with 2-4 holes, one of which is opened on the navel of the human body to avoid leaving long scars on the patient’s abdominal cavity, and after recovery, only 1-2 linear scars of 0.5-1 cm are left on the abdominal cavity, which can be said to be a small invasive and less painful surgery. surgery. The development of laparoscopic surgery has reduced the pain of open surgery, shortened the patient’s recovery period, and relatively reduced the patient’s expenses, making it a rapidly developing surgical program in recent years. Disadvantages of previous open surgery 1, trauma, slow recovery, heavy incision pain, long hospital stay 2, postoperative incision infection, cracking, incisional hernia, etc. 3, postoperative intestinal adhesions, intestinal obstruction, recurrent abdominal pain and other symptoms. 4. Gastric and urinary catheters need to be left in place before surgery, which brings great pain to patients. Minimally invasive surgery features 1. Small incision of only 0.5-1 cm, light scar, good cosmetic effect. 2. Less patient pain, less postoperative pain, no need to keep a gastric tube before surgery, no need to use pain medication after surgery. 3. Less intraoperative bleeding, some surgeries can be done without a drop of blood. 4. Quick recovery after surgery, you can leave the bed on the day of surgery, and you can be discharged from the hospital three days after surgery. Soon return to work and life. 5. The cost of surgery is relatively reduced (short postoperative hospitalization time, which can save the cost of bed and postoperative treatment). (1) Laparoscopic cholecystectomy is the best and most effective minimally invasive procedure in China. Almost all patients with gallbladder stones and gallbladder polyps in our hospital do not need open surgery, which really allows patients to experience the advantages of minimally invasive surgery. (2) Laparoscopic surgery for colon and rectal cancer is another gold standard surgery after laparoscopic cholecystectomy. The surgical effect is the same as that of open surgery, but the advantages of less pain and faster recovery far exceed those of open surgery in the past. (3) Laparoscopic splenectomy. Many patients with splenomegaly, hypersplenism, and blood disorders need to undergo splenectomy, which used to require a 20 cm surgical incision in the abdomen to complete the operation. (4) Laparoscopic intestinal adhesion release. Many patients have had abdominal surgery for diseases, and often have unexplained abdominal distension and abdominal pain after surgery, and there is no good treatment for such abdominal adhesions. Now there is a new progress and a qualitative leap in the treatment of this disease with laparoscopic instruments. At present, we have performed many such procedures and the patients are free from chronic abdominal pain after the operation. It shows the gospel brought by the new instrumentation and technology. (5) Laparoscopic abdominal exploration and pathology removal. Many difficult diseases can not be clearly diagnosed after many preoperative examinations, or there is a mass in the abdominal cavity preoperatively through a variety of examination methods based on the nature can not be clear, then you can consider laparoscopic exploration, if the lesion can be found in the laparoscope together with removal, examination and treatment in one, which really reduces the patient’s pain and medical costs. (6) laparoscopic gastric perforation repair, in the past, such emergency surgery required an incision in the abdomen and removal of one-half or more of the stomach to achieve the purpose of treatment, but currently our hospital uses laparoscopic gastric perforation repair, postoperative with regular acid suppression treatment has achieved satisfactory treatment results. This picture shows the abdomen without a long surgical incision after cholecystectomy.
