Hartmann's procedure versus primary anastomosis for Hinchey III or IV sigmoid diverticulitis: a propensity score analysis of a retrospective national cohort study.
Article in Surgical endoscopy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
introductionPrimary anastomosis with a diverting stoma (PA) has been evaluated relative to Hartmann's procedure (HP) for Hinchey III/IV peritonitis in four randomized trials, all of which lacked power. We aimed to evaluate the safety of PA for this indication in real-life settings. PATIENTS AND
methodsPatients who underwent surgery for Hinchey III/IV diverticulitis at 43 French centers from 2010 to 2021 were included in this retrospective multicenter study. The primary endpoint was the rate of severe complications at 90 days (Clavien-Dindo III-V). Secondary endpoints included the overall complication rate and stoma-free survival at one year. Two groups of patients (PA vs. HP) were created by propensity score matching (PSM).
resultsIn total, 651 patients were included (112 with PA and 539 with HP). We matched 102 of the patients with PA with 102 patients who underwent HP. On day 90, there was no difference in the rate of severe complications (31% vs. 29%, p = 0.75) between these groups in subgroup analyses for Hinchey III (p = 0.99) or Hinchey IV (p = 0.35) diverticulitis. The percentages of patients with Hinchey III or IV diverticulitis did not differ significantly between the groups (SMD = 0.03). After inverse probability treatment weighting, mortality was significantly higher in the HP group than in the PA group (6% vs. 1%, p = 0.019). Stoma-free survival at one year was higher in the PA group (85% vs. 73%, p = 0.03). The reoperation rate at 90 days was higher in the PA group than in the HP group (unadjusted: 21% vs. 13%, p = 0.028; PSM: 21% vs. 7%, p = 0.007, respectively).
conclusionPA did not increase the overall rate of complications. Conversely, it decreased mortality and the rate of definitive stomas in a large cohort of patients with Hinchey III/IV sigmoid diverticulitis.
