Suspension sutures facilitate single-incision laparoscopic-assisted rectal pull-through for Hirschsprung disease

To present a surgical technique of single-incision laparoscopic-assisted endorectal pull-through (SILEP) with suspension sutures using conventional instruments for Hirschsprung disease (HD) and its long-term follow-up outcomes.

The procedure began with a 1 cm transumbilical skin incision. Three separate punctures were made in the fascia with a 5 mm scope in the middle and 5 mm and 3 mm ports for working instruments on the left and right, respectively. The first suspension suture was placed to secure the sigmoid colon to the abdominal wall. A window was created through the rectal mesentery, and dissection around the rectum was carried out. The second suspension suture was performed to suspend the rectovesical peritoneal fold or the rectovaginal peritoneal fold to the abdominal wall. Dissection around the rectum was continued downward to approximately 1 cm below the peritoneal fold. Then, the operation was completed by a transanal approach.

Forty patients underwent SILEP from March 2013 to April 2015. The median age was 2.7 months (ranging from 1 to 17 months). The mean operative time was 96 ± 23 min. No conversion to an open operation was required. The average hospitalization time was 4.5 ± 2 days. There were no intraoperative or perioperative complications. Long-term follow-up results were obtained from 38 patients. A frequency of defecation from every other day to twice a day was noted for 33 patients (86.8%) and more often for 5 patients (13.2%). Two patients had enterocolitis (5.2%).

Single-incision laparoscopic rectal pull-through with suspension sutures using conventional instruments is feasible and safe for HD with good long-term outcomes.
