Hartmann's procedure reversal rate and short-term outcomes: a single centre retrospective cohort study.
Article in BMC surgery, 2026. 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
backgroundHartmann’s procedure is when all the sigmoid and/or rectum is removed with an end stoma in the left iliac fossa and the rectal stump closed off in the pelvis. This is often performed when bowel anastomosis is not feasible, too risky or deemed unsuitable for patients, either as planned operation or in an emergency, with reversal rate being less than 50%. The aim of our study was to establish the number of Hartmann’s procedure performed, its reversal rate in a single UK based NHS hospital, comparison between surgical approaches (laparoscopic vs. open) and evaluating short term clinical outcomes.
methodsA retrospective cohort study was conducted over a period of 13 years and 4 months (1st Jan 2011–31st May 2024). Exposures were (1) reversal status (reversed vs. non-reversed) and (2) surgical approach to reversal (laparoscopic vs. open). Patient demographics including smoking status, comorbidities, ASA, Rockwood frailty score, WHO performance status, and surgical indication were extracted. Outcomes included 30-day Clavien-Dindo morbidity, anastomotic leak, return to theatre, length of stay, readmission rate, and 30 and 90-day mortality.
resultsA total of 172 patients underwent Hartmann’s procedure during the study period, of whom 90 (52.3%) were reversed. The median follow-up was 67.25 months (IQR +/- 87). Forty-seven patients died during follow-up, 38 (81%) of whom were in the non-reversed group. Patients undergoing reversal were significantly younger, with fewer comorbidities, better ASA, frailty, and performance scores. Of the 90 reversals, 25 were completed laparoscopically, 35 were converted from laparoscopic to open, and 30 were performed as planned open reversals. Laparoscopic reversal was associated with a significantly shorter median length of stay (+/- 4 days); however, there was no difference in 30-day Clavien-Dindo morbidity between groups. There were two anastomotic leaks (2.2%) and two failed reversals in the open group, and one 30-day mortality in the laparoscopic group.
conclusionsOur single-centre UK experience shows higher rates of Hartmann’s reversal in younger, much fitter patients, shorter hospital stay in the laparoscopic reversal group, with acceptable short-term outcomes in both groups.
