Summary

Total colectomy with ileorectal anastomosis is a traditional surgical option for slow transit constipation (STC). Subtotal colectomy with caecorectal anastomosis have been reported to be a potential alternative approach. Thus, the optimal surgical option for STC is controversial.

Conditions

  • Slow Transit Constipation
  • Surgery

Interventions

PROCEDURE

Total colectomy with ileorectal anastomosis

Following complete colonic mobilization without preservation of the ileocolic vascular pedicle, the surgical specimen was extracted by extending the right lower quadrant trocar incision to approximately 4-5 cm. A resection of ileum, 2-3 cm proximal to the ileocecal junction, will be conducted by stapler. The anvil of a 29-mm circular stapler was inserted into the proximal ileal lumen and repositioned intra-abdominally. Ileorectal anastomosis was performed by transanal insertion of the circular stapler, aiming to achieve a tension-free, contamination-minimized reconstruction. Finally, a closed suction drain was placed in the rectouterine pouch (Douglas pouch), and all abdominal incisions were closed in layers.

PROCEDURE

Subtotal colectomy with cecal-rectal anastomosis

Following complete colonic mobilization with preservation of the ileocolic vascular pedicle and its branches, the surgical specimen was extracted by extending the right lower quadrant trocar incision to 4-5 cm. After insertion of the anvil from a 29-mm circular stapler through the ascending colon resection margin, a resection about 3 cm distal to the ileocecal junction will be conducted. The cecum was then positioned in the pelvis without rotational torsion, and an antiperistaltic cecorectal anastomosis was created between cecal fundus (after appendectomy) and the rectal stump. The anastomosis was performed via transanal insertion of the circular stapler to ensure tension-free, contamination-controlled reconstruction. Finally, a closed suction drain was placed in the rectouterine pouch (Douglas pouch), and all abdominal incisions were closed in a layered fashion.
