Laparoscopic intersphincteric resection and J-pouch reconstruction without laparotomy.

In some cases, a J-pouch is not created after laparoscopic intersphincteric resection (Lap-ISR), because this procedure usually does not involve laparotomy. This study aimed to develop a new technique for Lap-ISR and J-pouch reconstruction without laparotomy and to assess the short- and long-term outcomes of this technique. After a rectal specimen is excised using the transanal approach, the reconstructed intestine is reinserted into the intra-abdominal space. To create the J-shape, the reconstructed intestine is looped back using Allis forceps, and the septum of the J-shape is divided using a surgical stapler. We performed 20 surgeries using the new technique. Although three patients developed pelvic infections, no J-pouch-related complications were noted. Intestinal continuity could be maintained in all patients who received a diverting stoma.
