Laparoscopic-assisted natural orifice specimen extraction subtotal colectomy for redundant colon: a retrospective parallel-cohort comparative study with reduced surgical site infections and accelerated recovery.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Background: Redundant colon is one of the anatomical causes of slow transit constipation (STC). When conservative management fails, surgical intervention with subtotal colectomy is indicated. This study aimed to compare the perioperative outcomes of laparoscopy-assisted natural orifice specimen extraction (LA-NOSE) subtotal colectomy with conventional laparoscopy-assisted subtotal colectomy for redundant colon. Methods: A retrospective analysis was conducted on 34 patients with redundant colon who underwent laparoscopy-assisted subtotal colectomy with cecorectal anastomosis at the Affiliated Hospital of Chengdu University between January 2009 and January 2026. Of these, 16 patients underwent LA-NOSE and 18 underwent conventional surgery with a mini-laparotomy for specimen extraction. Categorical perioperative outcomes were compared using Fisher's exact test. Results: Baseline characteristics were comparable between the two groups. The LA-NOSE group showed certain advantages in postoperative recovery: sitting up within 24 h (87.5% vs. 38.9%, Conclusion: LA-NOSE subtotal colectomy is a safe and feasible minimally invasive option for redundant colon, offering accelerated postoperative recovery, reduced SSI, and superior cosmetic outcomes without compromising safety. This technique adheres to the principles of Enhanced Recovery After Surgery (ERAS) and offers an alternative treatment option for transnatural orifice specimen extraction in benign colonic diseases.
