Recently, with the cooperation of the Department of Anesthesiology and other related departments, Director Li Yuanxin of the Second District of General Surgery successfully completed laparoscopic-assisted total colectomy with rectal plus ileal pouch-anal anastomosis (IPAA) to treat ulcerative colitis with multiple stenosis of the colon resulting in complete intestinal obstruction in one case; Qiu Xiaochen, Department of General Surgery, 309th Hospital of the People’s Liberation Army, currently The standard surgical procedure for the treatment of ulcerative colitis is IPAA, which completely removes the target organ of colorectal lesions and, at the same time, ensures anal self-control because of the complete preservation of the anal sphincter, taking into account the curability of the disease and the patient’s quality of life, but not many surgeons in the field of surgery in China can perform IPAA (Cui Long, Chinese Journal of Gastrointestinal Surgery, 2013(16)4:319 -322), and even fewer surgeons and units can perform IPAA independently under laparoscopy; IPAA was reported in 1978 by Parks et al. The main steps are total colectomy, rectal mucosal debridement, preservation of the anal sphincter, and reconstruction of the rectum by remodeling the end ileum into a storage pouch. The ileal storage pouch anastomosis within the rectal muscle sheath is also performed. The techniques of this procedure include: (1) design of the storage pouch: the function of the storage pouch mainly depends on the compliance of the ileum, the perfect function of the anal sphincter and the complete anal nerve reflex, the J-shaped storage pouch is the commonly used form of the storage pouch, the design of the storage pouch is the key to the recovery of the patient’s postoperative fecal function, the key to the design of the storage pouch is the way of anastomosis and the height of the storage pouch; (2) transanal mucosal resection with ileal storage pouch-anal tube anastomosis (3) laparoscopic techniques: total colectomy includes all four quadrants of the abdomen, which is equivalent to four procedures of right hemicolectomy, transverse colon cancer, radical left hemicolectomy, and anterior rectal cancer resection, during which the operator, assistant and mirror-supporting hand need to change positions several times, which requires higher operator skills and overall team cooperation; compared with other laparoscopic total colectomy procedures, UC’s laparoscopic total colectomy First, UC lesions lead to more brittle colonic tissue, which is prone to bleeding during separation; second, the long duration of UC disease and recurrent chronic inflammation lead to heavy intra-abdominal adhesions and the disappearance of normal anatomical gaps, which enhances the difficulty of separation; third, the colorectal mesentery of UC patients is generally thickened and thickened, which increases the difficulty of rectal resection and bare bowel.
