It represents the latest development in the concept of a minimally invasive surgery for HD. We introduce a new method of transanal one-stage pull-through for Hirschsprung＇s disease, different from the transanal Scare procedure. Methods One hundred and thirty-four patients aged 9 days to 5 years underwent a transanal one-stage pull-through procedure. The diagnosis was definite by barium enema or rectal biopsies preoperatively. The patients were anesthetized and placed in the lithotomy position. A urinary catheter was optional. Giving anorectal dilatations for half a minute, a pull-through of the rectum above the peritoneal reflection and into the intussusception was performed. Fine silk suturing was performed circumferentially at the level of that point which was used for traction for the distal end. Another circumferential suture was performed parallel 0.5 cm distance above the original one and used for traction for the proximal intestines. The full-thickness rectal wall was truncated between the above two circumferential sutures with cautery. The proximal intestines were pulled down and the mesenteric vessels were dissected with ligation until normal intestines were accessed; the presence of ganglion cells was determined by intraoperative rapid frozen section. The distal end was dissected anteriorly 2.5-3.5 cm above the dentate line. The posterior rectal wall was split longitudinally and dissected to a point 0.5-1.0 cm above the dentate line. The segment of the lesion was resected. The length of bowel resected ranged from 12 to 50 cm （median 16.5 cm）. An oblique anastomosis was made. Results The mean operating time was 70 minutes. Postoperative rectal dilation was not required. The patient tolerated feeding on the first postoperative day. Eighty-eight patients were followed-up. All these patients had 2-展开更多

Materials： ILTPT was performed in 4 patients. Five or 4 ports were used. After isolation and section of the inferior mesenteric vessels, the rectum and sigmoid colon was mobilized. Total mesorectal excision and dissection of the distal rectum from the puborectalis muscle was carried out under laparoscopic guidance. The sigmoid colon and rectum were exteriorized via the anus. The rectum was divided proximally. Next, a purse-string suture was placed in the proximal segment, and the distal end of the sigmoid colon was returned to the pelvic cavity. The distal rectum was divided with Curved cutter staplermade by Jonson-Jonson company. Dislodging specimen, the continuity of the intestinal tract was restored using PROXIMATE ILS Curved and Straight Intraluminal Staplers CDH29/33 （Ethicon） through the rectum. Results： None of the cases were converted to open surgery. Average operation time was 180 min （range, 160-210 min）. No blood loss or any other complications were noted. Average postoperative stay was 9 days. Complications such as necrosis, anastomotic leakage and stricture, and genitoudnary disorders were not found in any of the patients at the 1 m follow-up. Conclusion： This report suggests that ILTPT is feasible and safe in Anus-Conserving Operation for low Rectal Cancer without auxiliary incision. If only we hold the applicability of ILTPT less trauma, more beautiful.展开更多
