Laparoscopic Surgery for Colovesical Fistula Caused by Colonic Diverticulitis: A Retrospective Study at a Single Center.
Article in Cureus, 2025. 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 Colovesical fistulas caused by colonic diverticulitis are relatively rare but require surgical intervention. Recent advancements have enabled laparoscopic approaches, although standard procedures are yet to be established. Objective To evaluate the safety and efficacy of laparoscopic surgery for colovesical fistula and compare outcomes with those for Hinchey I/II diverticulitis without fistulas. Methods We retrospectively reviewed 48 patients who underwent laparoscopic surgery for colonic diverticulitis from January 2015 to August 2024. Of these, nine had colovesical fistulas. Operative time, blood loss, and postoperative hospital stay were compared using Welch's t-test. Results The mean operative time was 381.2 ± 175.0 min in the fistula group and 308.1 ± 120.5 min in the non-fistula group (p = 0.262). Mean blood loss was 162.8 ± 167.4 mL and 130.8 ± 197.7 mL, respectively (p = 0.626). Mean postoperative hospital stay was 7.7 ± 1.12 days and 7.4 ± 2.27 days (p = 0.626), respectively. There were no conversions to open surgery, and no recurrences or severe complications were observed. Conclusion Laparoscopic surgery for colovesical fistula is feasible and achieves outcomes comparable to standard cases of Hinchey I/II diverticulitis. A standardized "all-in-one" laparoscopic technique can be applied even in cases with fistulas.
