Endoscopic Management of Appendiceal Stump Lesions via Transcolonic Access: A Safe and Feasible Minimally Invasive Strategy.
Article in Journal of gastroenterology and hepatology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 AND
aimTranscolonic endoscopic appendectomy is an emerging minimally invasive alternative to traditional appendectomy, offering potential benefits such as reduced postoperative pain, faster recovery, and avoidance of external incisions. The variable anatomical location of the appendix, however, influences both the surgical approach and technical difficulty. The appendiceal stump-defined as the residual portion of the appendix after prior appendectomy-poses a unique challenge, as the main body of the appendix has already been removed. This study aimed to evaluate the feasibility, safety, and efficacy of transcolonic endoscopic appendectomy for the removal of appendiceal stump lesions.
methodsThis retrospective study included patients who underwent the procedure between December 2020 and December 2024 after prior appendectomy for appendiceal remnant lesions. The primary outcome was technical success; secondary outcomes included postoperative complications, hospital stay, and recurrence.
resultsNine patients (mean age 60.7 years; 4 males, 5 females) were included. Lesion size averaged 1.34 cm. Complete en bloc resection was achieved in all cases. Mean operative time was 70 min, with fasting and hospitalization durations of 3.4 and 5.8 days, respectively. No postoperative complications occurred, and 3-month colonoscopy showed no residual lesions or recurrence.
conclusionsTranscolonic endoscopic appendectomy for appendiceal stump lesions is a safe and effective minimally invasive treatment option within experienced endoscopic centers. Due to their anatomical simplicity, these lesions represent a straightforward indication, making the procedure suitable as an entry-level application for endoscopists. Further investigation and structured training programs are warranted to assess long-term outcomes and broaden the generalizability of this technique.
