Intracorporeal anastomosis versus extracorporeal anastomosis for laparoscopic right hemicolectomy: short-term and long-term outcomes.
Article in Surgical endoscopy, 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
backgroundLaparoscopic right hemicolectomy is the standard of care for non-locally advanced right-sided colonic neoplasms and endoscopically unresectable polyps amenable to laparoscopic resection, but the optimal ileocolic anastomotic technique remains debated. This study compares intracorporeal anastomosis (ICA) and extracorporeal anastomosis (ECA) outcomes in laparoscopic right hemicolectomy performed by three surgeons at a Canadian community hospital.
methodsThis retrospective study analyzed patients who underwent elective laparoscopic right hemicolectomy with ICA using Pfannenstiel extraction or ECA using midline extraction at a Canadian community hospital from January 1, 2015, to December 31, 2023. Descriptive statistics, univariable, and multivariable Firth penalized logistic regression were performed to identify predictors of postoperative outcomes.
resultsOf 203 patients, 150 (73.9%) underwent ICA and 53 (26.1%) had ECA. No significant differences in baseline characteristics were observed between groups. Operative times were similar (ICA: 151.9 min vs. ECA: 146.1 min, p = 0.319). ICA was associated with faster gastrointestinal recovery (first flatus: 2.0 vs. 3.5 days, p < 0.001), shorter hospital stays (2.8 vs. 5.0 days, p < 0.001), and lower rates of ileus (5.3% vs. 24.5%, p < 0.001), incisional hernia (0.0% vs. 7.5%, p = 0.004), and adhesive small bowel obstruction (0.0% vs. 5.7%, p = 0.017). No anastomotic leaks occurred in either group. On multivariable Firth regression, ECA was an independent predictor of postoperative complications (aOR 2.60, 95% CI 1.27-5.34), ileus (aOR 6.38, 95% CI 2.50-17.44), incisional hernia (aOR 30.16, 95% CI 3.17-3928.8), and adhesive SBO (aOR 20.86, 95% CI 1.97-2823.4).
conclusionsICA was associated with faster recovery of bowel function, fewer complications, and shorter hospital stays compared to ECA, with comparable operative times. These findings support ICA as a feasible technique for ileocolic anastomosis in a community hospital setting and suggest it is associated with improved short- and long-term outcomes compared to ECA.
