Appropriateness of Prophylactic Surgery for Sigmoid Volvulus in View of Recurrence and Nutritional Status.
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 Sigmoid volvulus causes colonic obstruction and ischemia. Urgent surgery is required for colonic necrosis or perforation, whereas prophylactic surgery is recommended after endoscopic treatment in nonemergency cases. However, many patients with sigmoid volvulus only undergo endoscopic treatment, highlighting a gap between guideline recommendations and clinical practice. We aimed to elucidate the actual management and outcomes of sigmoid volvulus in hospitalized patients to reconsider the disadvantages of delaying prophylactic surgery. Methods We retrospectively recruited patients with sigmoid volvulus who were treated at the Hoshigaoka Medical Center between January 2013 and September 2024. Participant demographics and outcomes were analyzed, and the probability of remaining recurrence-free was estimated using Kaplan-Meier analysis. Wilcoxon signed-rank tests were used to compare paired samples. Results We enrolled 28 participants with sigmoid volvulus. Of these, 15 (53%) had a medical history of cerebral stroke, and 12 (42%) were institutionalized. No participants who underwent surgery experienced recurrence, whereas 10 (62%) of 16 participants who received only endoscopic treatment did. Among patients with recurrence, one died as a result. Body weight, serum albumin level, geriatric nutritional risk index, and prognostic nutritional index were significantly lower at the time of recurrence than at the first hospitalization. No deaths occurred due to postoperative complications. Conclusions Sigmoid volvulus frequently recurs after endoscopic treatment alone, posing a life-threatening risk with each recurrence. Most patients with sigmoid volvulus are frail, and their nutritional status often deteriorates before recurrence occurs. Prophylactic surgery should therefore be planned for sigmoid volvulus soon after endoscopic treatment for the first time.
