sigmoid colon artificial vaginoplasty

1. Congenital without vagina. 2. Uterine or vaginal malignant tumors, most or all of the vaginal resection. Treatment of diseases: congenital absence of vaginal malignant tumors Indication 1. Congenital without vagina. 2. Uterine or vaginal malignant tumors, most or all of the vaginal resection. Preoperative preparation 1. 3 days before the operation of the intestinal preparation. 2. Clean the enema 1 day before surgery, fasting in the morning and staying in the stomach and gastrointestinal decompression. Surgical procedure 1. Position and disinfection: take the bladder lithotomy position or the supine herringbone position, divided into two parts: the abdomen and the genitals. Conventional field disinfection. 2. Abdominal surgery: (1) free sigmoid colon: after laparotomy or gynecological cancer, after treatment, choose a free sigmoid colon length of about 12cm, identify and retain the sigmoid colon in the mesenteric root, according to the choice of intestinal site, respectively cut off the sigmoid colon and the left colon The arterial descending branch belongs to the branch, which is equivalent to: the upper part of the sigmoid colon rising from the level of the sputum, and the end of the sigmoid colon, and the distal and distal intestine segments are respectively cut off. (2) Treatment of the intestinal segment: The sigmoid colon was end-to-end anastomosis as usual, and the defect of the mesentery was sutured intermittently (Fig. 14). The distal part of the free sigmoid colon was sutured continuously with a silk thread, and the proximal end of the heart was sutured separately by the mucosal layer and the sarcoplasmic layer to close the intestinal lumen. 3. Abdominal-pubic surgery: (1) Artificial vagina formation: the distal end of the free sigmoid colon segment is pulled from the pelvic cavity through the vaginal cavity to the vaginal margin of the vaginal canal or the vaginal stump after resection, the incision line of the intestine is removed, and the margin of the intestine is cut off from the vaginal opening or The vaginal stump is aligned and then sutured to form an artificial vagina. (2) Fixing the free sigmoid colon: suture the pelvic peritoneum intermittently around the free sigmoid colon, so that the 1/3 segment of the transplanted intestine is in the peritoneum and the 2/3 segment is in the peritoneum. The mesentery of the free sigmoid colon segment is fixed to the peritoneum of the pelvis to prevent intestinal incarceration. 4. Rinse the artificial vagina and block the oil yarn and stay in the catheter.
