Objective:

To evaluate the short- and long-term efficacy of laparoscopic-assisted subtotal colectomy cecal-rectal anastomosis (SCC-CRA) in patients with redundant colon who have slow-transit constipation.

Approach:

• Study Design: Retrospective analysis of 34 patients who underwent laparoscopic-assisted SCC-CRA between January 2016 and June 2025 at Chengdu University Affiliated Hospital.

Key Findings:

• All 34 patients successfully underwent the procedure without conversion to laparotomy.
• At 8 months postoperatively, all patients achieved more than three bowel movements per week, compared to 94.1% preoperatively.
• Straining during defecation resolved completely, and hard or lumpy stools were eliminated.
• Bowel frequency normalized over time, with a low reported incidence of diarrhea.
• No symptomatic recurrence was observed during long-term follow-up.

Interpretation:

Laparoscopic-assisted subtotal colectomy cecal-rectal anastomosis is feasible with acceptable short-term outcomes, providing significant and durable relief of constipation symptoms with a low risk of postoperative diarrhea.

Limitations:

• The study is retrospective and conducted at a single center.
• Long-term follow-up data were only available for a subset of patients.

Conclusion:

Laparoscopic-assisted subtotal colectomy cecal-rectal anastomosis is a viable surgical option for patients with redundant colon, demonstrating favorable outcomes.
