[Choice of surgical procedures and control of surgical risks in chronic constipation].

Surgery, as one of the methods for the treatment of chronic constipation, is the final choice after the failure of non-surgical treatment with its specific particularity. The history of surgical treatment of chronic constipation is complex and tortuous. How to select operation among many kinds of surgery, and control risk is difficult for clinician. The choice of surgical procedure depends mainly on the patient's conditions, the objective examination basis and the experience of physician teams. Based on the previous reports and the team's experience, this paper discusses the choice of surgical treatment for the following types of chronic constipation: (1) Slow transit constipation: subtotal colorectal resection plus ileorectal anastomosis or ascending colon rectum anastomosis is widely used at present in the domestic, and its efficacy is quite good. (2) Outlet obstructive constipation: surgical treatment needs to be cautious with no consensus, and surgeons must follow the advice of "minimally invasive first" principle. (3) Mixed constipation: there is no clear and unified surgical treatment, while Jinling surgery is a promising way of operation. (4) Adult Hirschsprung's disease: surgery is the only treatment, and removing the stenosis segment, transitional segment and obvious expansion segment is the basic principle, and preventive ileostomy at the same time is also recommended. (5) Adult idiopathic megacolon: subtotal colectomy with ileorectal anastomosis or ascending colon rectum anastomosis is highly recommended. (6) Hypoganglionosis: it is rare, and no consensus has been reached in surgical treatment. How to select the proper timing and mode of operation, and how to control the operation risk are the contents that clinicians must master. With the development of laparoscopic surgical technology, minimally invasive surgery is becoming the main direction of constipation treatment.
