Restorative colorectal resection with ileal storage bag and ileo-anastomosis

Reconstructive large intestine rectal resection ileal storage bag and ileal anal anastomosis is a surgical procedure in which a part of the patient's ileum is made into a fecal storage bag and anus is anastomosed while the patient's diseased large intestine is removed. After a period of adaptation, the patient can be like Normal people have the same bowel movements. Treatment of diseases: chronic ulcerative non-granulomatous jejunum ileitis chronic ulcerative colitis Indication Surgery is mainly used for cases of chronic ulcerative colitis that are ineffective for medical treatment, uninterrupted extraintestinal manifestations, persistent small amounts of bleeding, stenosis or severe mucosal changes. Preoperative preparation 1. Admitted 4 weeks before surgery, less slag diet, daily oral liquid paraffin 60ml, enema 1 or 2 times. 2. Oral administration of succinyl sulfonamide and other drugs 2 weeks before surgery. Such as combined with colitis, repeated diarrhea, can be repeated with normal saline irrigation, 3 times a day, and oral neomycin 50mg ~ 100mg / kg · d, 3 to 4 times orally. Surgical procedure Position: The child is lying on the large plate, the buttocks are high, and the perineum is placed on the edge of the large plate to facilitate the operation of the perineum. The upper and lower limbs are fixed on the large plate, and the left iliac vein is cut. The right lower limb is not fixed, so that the perineal movement can be moved casually. Place the indwelling catheter. Incision: The left lower right midside incision, from 1 cm above the umbilicus to the upper edge of the pubis, 6 to 7 cm long. Abdominal exploration: After entering the abdominal cavity, the sigmoid colon was inspected outside the incision, and the dilated sigmoid colon was gradually changed into a narrow rectal segment, which is a segmental intestine with no ganglion. The intestines above the sacral section are expanded second, the intestinal wall is thick, pale, tarnished, the colonic band is sparse, and the intestines lose their peristaltic function, usually turning to the upper part of the descending colon. The above abnormal intestinal fistula should be completely removed. Separation of the rectum and sigmoid mesentery: incision of the sigmoid mesentery and the rectum on both sides of the rectum and the rectal bladder fossa, taking care not to damage the ureters on both sides. In order to make the sigmoid colon fully active, the sigmoid colon should be cut off, and the ligation and cutting should be close to the starting point of the artery, so that the vascular arch can be preserved and the intestinal wall can be fully transported. The trunk and branches of the left colonic artery are preserved to ensure blood supply to the proximal colon. If you need to remove most of the descending colon, you sometimes need to cut the left colon. Separated in the upper part of the rectum, reaching the level of the levator ani muscle at the bottom of the basin. In order to avoid damage to the bladder nerve, the rectum should be separated as close as possible to the intestinal wall. The upper and middle iliac arteries encountered during the anatomy need to be ligated and cut. Resection of the sigmoid rectum, temporary suture of the stump: removal of the huge sigmoid colon and rectal stenosis. When there are conditions, the sigmoid colonic wall tissue should be taken for frozen section examination; if it is not normal, it should be removed again. First suture the proximal colonic end, and use a white line on the mesangial side, a black line on the side of the mesial (or a thin line on one side and a thin line on the other side) to prevent the bowel from being pulled out. Reversed. Then, the rectal stump was continuously sutured with a silk thread, and the muscle layer of the intermittent pulp was sutured. Pull out the rectum and colon stump: insert a 0.1% Zephyr or thiomersal gauze ball from the anus with a long hemostasis or an oval clamp. After disinfecting the rectum, use your left hand to press the rectum from the pelvis. End, and use the oval clamp to clamp the inner wall of the rectal stump, pull out the anus, and turn the rectum stump out to become the outer sleeve of the mucosa. The anterior wall of the rectal stump was cut transversely about 3 cm above the tooth line. Then, insert a long curved hemostatic forceps into the pelvic cavity from the incision, clamp the traction line of the proximal colon stump, and pull the proximal colon out of the anus about 4 cm, taking care not to twist the intestine. Anastomosis of the rectum, colon: suture the anterior wall muscle layer of the rectum and the anterior wall of the colon before the anus, and then remove the excess rectum from the anus, suture the posterior wall of the rectum and the posterior wall of the colon. Then, the proximal wall of the proximal colon is cut open, the contents of the colon are exhausted, and the rectum and the anterior wall of the colon are sutured in a full layer. Finally, the posterior wall of the colon is cut, and the rectum and the posterior wall of the colon are sutured together until the excess colon is removed, and the colon and rectum are anastomosed outside the anus. The anastomosis is returned to the anus, and the cigarette is drained on the posterior side of the anastomosis, and is introduced through a small incision on the posterior side of the anus. After the peritoneal incision was sutured, the abdominal wall incision was closed layer by layer. complication Gastrointestinal discomfort.
