A laparoscope is an instrument with a miniature camera. Minimally invasive laparoscopic surgery 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 post-processing system and displayed in real time on a special monitor using digital camera technology. 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 area, and after recovery, only 1-2 linear scars of 0.5-1 cm are left on the abdominal area, 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 procedure in recent years. Disadvantages of previous open surgery: 1, trauma, slow recovery, heavy incision pain, long hospital stay 2, postoperative incision infection, splitting, 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.Fast 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 and resume work and life soon. 5, the cost of surgery is relatively reduced. At present, 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 brought by minimally invasive surgery. 2.Laparoscopic colon cancer and rectal cancer surgery is another gold standard surgery after laparoscopic cholecystectomy. The surgical effect is the same as open surgery, but the advantages of less pain and faster recovery far exceed the previous open surgery. 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, but now with laparoscopy, only 3-4 1 cm holes in the abdomen can be completed. 4.Laparoscopic intestinal adhesion release. 5, laparoscopic abdominal exploration, pathology removal surgery. Many difficult diseases can not be clearly diagnosed after many preoperative examinations, or the abdominal cavity has a mass preoperative through a variety of examination methods based on the nature can not be clear, then you can consider laparoscopic exploration, if found lesions can be removed together under the laparoscope, examination and treatment in one, which really reduces the patient’s pain and medical costs. 6, laparoscopic gastric perforation repair.
