Comparison of recurrence and mortality rates between resection and non-resection surgical methods for treating sigmoid volvulus: a systematic review and meta-analysis.

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
purposeThis systematic review and meta-analysis aims to compare the recurrence and mortality rates of resection versus non-resection surgery for sigmoid volvulus (SV), a condition requiring a balance between recurrence prevention and mortality minimization.
methodsA comprehensive search of PubMed, EMBASE, Web of Science, and Cochrane Library identified studies comparing resection and non-resection surgeries for SV. Primary outcomes included recurrence rates, and secondary outcomes included mortality rates. Randomed effects models were used to calculate pooled effect sizes.
resultsA total of 28 nonrandomized studies, comprising 837 resection and 660 non-resection patients, were included. Resection significantly reduced recurrence (RR: 0.12, 95% CI: 0.06-0.24, P < 0.001) with an NNT of 6 (95% CI: 5.7-7.0) but it was associated with increased mortality (RR: 1.69, 95% CI: 1.17-2.44, P = 0.005, NNH = 17 [95% CI: 11.1-33.3]). Subgroup analysis excluding gangrenous sigmoid patients showed resection effectively prevented recurrence (RR: 0.20, 95% CI: 0.08-0.50, P < 0.001, NNT = 9 [95% CI: 6.2-13.7]) with no significant mortality difference (RR: 1.12, 95% CI: 0.53-2.37, P = 0.760). Similar results were observed in sensitivity analyses excluding studies published before 1990, analyses limited to prospective studies, and when comparing resection with specific non-resection procedures.
conclusionsResection is effective in preventing SV recurrence, with no significant mortality increase in patients with virable colon, supporting its use in suitable patients. Future research should optimize patient selection and perioperative care.
