Ten years after diagnosis of Crohn’s disease, 40-70% of patients require surgery. However, some patients have more stable disease control with conservative treatment and are able to maintain remission for a longer period of time. 1. What are the indications for surgery in Crohn’s disease? Indications for surgery include: intestinal obstruction, internal and external fistula, perforation, hemorrhage, cancer, playful infection, intestinal or extraintestinal symptoms that cannot be relieved by medication, and serious complications from hormonal or other medication. 2, the choice of surgery for Crohn’s disease? For lesions in the small intestine or colon, surgical options include bowel resection, stenoplasty and lesion extraction, and fecal diversion. For patients with combined perianal disease, the treatment of anal fistula should first fully drain the abscess, and the fistula can be incised or threaded after formation. 3.What are the advantages and disadvantages of laparoscopic and open surgery? Laparoscopic surgery has the advantages of less injury, less pain, faster recovery and no obvious surgical scars on the abdomen. However, not all patients are suitable for laparoscopic surgery. For some patients with a history of multiple previous surgeries and serious abdominal adhesions, laparoscopic surgery is often more difficult. 4, after surgery will recur? According to the Crohn’s and Colitis Foundation of America, once Crohn’s disease is diagnosed, up to 80% of patients require bowel resection within 20 years, and 20%-30% of these patients recur within one year after surgery, and the recurrence rate continues to increase. Postoperative recurrence is also quite common in children with Crohn’s disease. In a study of 100 patients with postoperative Crohn’s disease, the recurrence rate of clinical symptoms was 17% at 1 year, 38% at 3 years, and 60% at 5 years. 5.How to prevent recurrence after surgery? After surgical treatment of Crohn’s disease: 1. Smokers must quit smoking; 2. Continue to take medications to prevent recurrence as prescribed by the treating physician, including mesalazine (which can reduce recurrence of Crohn’s disease in the small intestine, but not in the colon), azathioprine (which may be better than mesalazine), and metronidazole (which requires attention to side effects, such as peripheral neuropathy); 3. Follow up regularly, follow up on discomfort, and seek medical attention for changes in condition promptly seek medical attention. 6.How long does it take to review after surgery? It is better to review once every 3 months after the surgery. If the review is good, you can review once every 6 months and seek medical consultation if there is any change in the condition. 7.How to treat after recurrence? The treatment of recurrence is generally the same as that before surgery, but there are special features, such as endoscopic balloon dilation for anastomotic stenosis.
