In recent years, the application of laparoscopic technology in gastrointestinal surgery has achieved rapid development. The advantages of laparoscopic minimally invasive surgery for gastric cancer, colorectal cancer, appendix, hemorrhoids, and anal fistula have been recognized by more and more surgeons and patients. The application has gradually been promoted and popularized, showing broad prospects.
1. The advantages of laparoscopic technology for colorectal cancer
1. Reduce surgical trauma. Most postoperative pain is directly related to the length of the abdominal incision. The micro incisions of laparoscopic surgery are consistent with the milder postoperative pain response.
2. Reduce surgical pain and use of anesthetics.
3. After surgery, the time of intestinal paralysis is shortened, early eating, and hospitalization time are reduced. Compared with open surgery, the recovery time after laparoscopy is earlier, which is related to the early recovery of intestinal function.
4. The recovery time is short, so related complications are reduced. Possible reasons include: faster recovery of lung function, less bleeding during surgery, and early patient activity after minimally invasive surgery. The performance of elderly patients is more obvious. Research suggests that the incidence of postoperative complications in the laparoscopic group is only 50% of that of open surgery.
2. Laparoscopic appendectomy
①The minimally invasive advantages of laparoscopic appendectomy. After laparoscopic appendectomy, the pain is small and the recovery is quick. You can get out of bed on the day of the operation, eat and drink the next day, and leave the hospital in three days; there is no scar on the abdomen, and the appearance is beautiful.
②There are very few wound complications. A common complication after appendicitis surgery is wound infection, some of which also lead to incisional hernia. During laparoscopic surgery, the appendix has no contact with the surgical channel, and wound infection and incisional hernia will hardly occur. We carried out laparoscopic appendectomy, and no wound complications occurred.
③ There are few adhesions in the abdominal cavity, and adhesive intestinal obstruction does not usually occur after surgery. The primary cause of intestinal adhesion and obstruction is surgery, and appendectomy is the first. The probability of intestinal adhesions in laparoscopic appendectomy is much lower than that of surgical operation, which has been confirmed by clinical observations for many years.
④ Laparoscopic surgery has a wide field of view, which can observe the entire abdominal cavity and find other lesions in the abdominal cavity. Traditional surgical surgery can only observe the condition of the appendix and may miss other lesions (such as colon cancer).
In short, laparoscopic appendectomy is safer and more effective than open surgery.
3. Video-assisted anal fistula treatment
4. Minimally invasive treatment of hemorrhoids (PPH)
PPH minimally invasive surgery, also known as circumcision of the hemorrhoids, is a new technique based on the theoretical basis of the pathogenesis of hemorrhoids caused by anal pad lesions. A special instrument called "PPH stapler" is used during the operation. The prolapsed rectal mucosa above the hemorrhoids was cut out with a loop. You can defecate normally within 24 hours after surgery, without pain, and does not affect the quality of daily life. A large number of clinical practices have proved that PPH minimally invasive technology has achieved impressive results in the treatment of hemorrhoids. It solves the medical problem that hemorrhoids are difficult to cure and easy to relapse.
The advantages of PPH surgery compared to traditional hemorrhoid surgery are as follows:
1. Safety: There is no need to remove the anal cushion, and the normal function of the anus is preserved to the greatest extent to avoid complications such as anal stricture and anal incontinence.
2. Painless: Pull back the hemorrhoids that have prolapsed from the anus, and cut off the blood vessels that provide blood to the hemorrhoids, without damaging the perianal skin, so there is almost no pain after the operation.
3. Small trauma and quick recovery: The circular stapling of the mucosa is a non-open wound, with less bleeding, eliminating the trouble of dressing change after surgery, and returning to normal life quickly.
4. Scope of diagnosis and treatment: ring hemorrhoids, multivalve hemorrhoids, huge isolated hemorrhoids, internal hemorrhoids, external hemorrhoids, mixed hemorrhoids, ring hemorrhoids, incarcerated hemorrhoids, rectal mucosal prolapse, prolapse, etc.
5. Suitable target: Because of less damage, it is especially suitable for middle-aged and elderly people, white-collar workers who pay attention to efficiency, and those who have relapsed in traditional treatment, and patients with mild prolapse and rectal mucosal prolapse.
