To study the safety and efficacy of laparoscopic subtotal colectomy (LASC) with cecorectal anastomosis for slow-transit constipation (STC).

This study was a retrospective review of all patients undergoing LASC with cecorectal anastomosis for STC between March 2010 and May 2017. The main variables included the operative time, blood loss, length of postoperative hospital stay, complications, and long-term outcomes.

In this analysis, 56 patients were included. There were 17 males and 39 females aged between 34 and 80 years old. The mean operative time was 208 ± 21 min, and the mean perioperative blood loss was 116 ± 48 mL. The mean postoperative hospital stay was 7.7 ± 3.5 days, and the incidence of perioperative complications was 19.6%, with no mortality. One patient required reoperation because of intra-abdominal bleeding. During the follow-up period, 26.8% of patients suffered from chronic pain and bloating, with no recurrence of STC. The causes of these symptoms included small bowel obstruction (7.1%), slow transit (10.7%), anastomotic stenosis (5.4%) and gastroptosis (3.6%). Postoperatively, after 12 months, the frequency of defecation was 2-4 times per day. Patients with follow-up of at least 60 months, the mean frequency of defecation was 0.9 ± 0.5 times per day. The percentage of satisfaction was 82.1%.

LASC with cecorectal anastomosis is a safe and effective surgical approach for STC, with the majority of patients being satisfied with the outcome of surgery.
