In acute severe colitis, does laparoscopic subtotal colectomy result in lower postoperative complication rates than open subtotal colectomy

What is known

- 2026 meta-analysis of 14 studies (6,544 patients) found laparoscopy reduced odds of postoperative morbidity vs open (pooled OR 0.49, 95% CI 0.45–0.53, p<0.0001). ¹ - The same analysis reported significantly shorter hospital stay with laparoscopy, robust across surgical eras and study designs; sensitivity analysis excluded registry-driven results. ¹ - The earlier case-matched study of 88 patients found similar (not lower) overall morbidity (35% vs 56%, NS) and similar operative time and stay between laparoscopic and open subtotal colectomy. ²

What is unknown / caveats

- Older case-matched/cohort studies found morbidity and length of stay comparable rather than reduced ^2,3 - Pooled evidence is built from retrospective cohorts and case-matched/case-control studies, not RCTs. Selection bias toward stabler patients for laparoscopy is likely - Toxic megacolon and hemodynamic instability often mandate laparotomy, so the laparoscopic groups may be a healthier subset - Residual confounding by indication means the observed morbidity benefit cannot be fully separated from patient-selection effects.
