Laparoscopic versus open emergency colonic resection for obstruction: a multicentre retrospective cohort study.
Observational study 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
backgroundDespite its established benefits in elective colorectal surgery, the adoption of laparoscopy in the emergency setting remains limited. This retrospective international multicentre study assesses laparoscopic and open colonic resection in patients with acute benign or malignant colonic obstruction.
methodsPatients were included between 2022 and 2023. Intraperitoneal free air on imaging was an exclusion criterion. Primary outcomes were the Comprehensive Complication Index (CCI) and length of stay (LOS). Secondary outcomes included postoperative pain management, re-operation, 30- and 90-day mortality, R0-resection and lymph node yield when applicable, intraoperative bleeding, anastomosis and operative time.
resultsOut of 144 patients, 73 were eligible. Forty-three (58.9%) patients underwent open and 30 (41.1%) laparoscopic resections. Obstructions were equally distributed between the right and left colon. Patients in the open group were older (77.1 vs. 61.7 years, p < 0.001). Clavien-Dindo II-V complications were more common (69.8% vs. 33.3%, p = 0.002) and the CCI was higher (27.1 vs. 7.9, p < 0.001) after open surgery. LOS was significantly longer after open surgery (14 (IQR 8-19) vs. 6 (IQR 5-9) days (p < 0.001)). Postoperative pain was managed with patient-controlled opioids and/or oral analgesics in 86.7% after laparoscopic surgery while an epidural was used in 76.7% after open surgery (p < 0.001). Other secondary outcomes were comparable between the groups.
conclusionLaparoscopic emergency resection in patients with acute benign or malignant colonic obstruction was associated with lower postoperative morbidity, shorter LOS and less intensive postoperative analgesic requirements in a selected cohort. However, these findings should be interpreted cautiously given substantial differences in baseline characteristics and surgeon specialization between groups.
