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
purposeSigmoid resection with end colostomy (Hartmann's procedure) is the procedure of choice when a large bowel obstruction secondary to diverticular disease requires surgery. Less morbid alternatives are less common. This study compares a transverse blowhole colostomy as a first-stage intervention in diverticular-associated obstruction. Our primary aim was to compare colostomy reversal rates and postoperative outcomes between blowhole colostomy and Hartmann's procedure.
methodsThis is a single-center, retrospective cohort study. An institutional database was utilized to retrospectively identify adult patients who underwent Hartmann's procedure or blowhole colostomy for diverticular strictures with obstruction between 2012 and 2023.
resultsThirty-nine patients underwent Hartmann's procedure for diverticular strictures with obstruction and 15 patients underwent blowhole colostomy. The blowhole colostomy group had a significantly shorter postoperative length of stay (median 5 vs. 8 days, p = 0.01). Colostomy reversal was more frequent in the blowhole group (81.3% vs. 56.4%, p = 0.08), with a shorter median time to reversal (3 months vs. 4.7 months, p = 0.01). A significant increase in reversals performed using a minimally invasive approach (84.6% vs. 50%, p < 0.01) occurred in the blowhole colostomy group. No significant differences were observed in other postoperative outcomes, including proximal diversion after colostomy reversal.
conclusionsBlowhole colostomy may be a viable alternative to a Hartmann's procedure for diverticular-associated large bowel obstruction, offering potential benefits such as shorter hospital stays, higher rates of colostomy reversal, and a greater likelihood of minimally invasive reversal. Further prospective studies are needed to confirm these findings.
