Bowel function after laparoscopic right hemicolectomy: a randomized controlled trial comparing intracorporeal anastomosis and extracorporeal anastomosis.

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
backgroundThe laparoscopic right hemicolectomy is the standard surgical treatment for right-sided colon cancer. The continuity of the digestive tract is restored through ileocolic anastomosis which can be performed extracorporeally or intracorporeally. The study aimed to compare both anastomotic techniques in laparoscopic right hemicolectomy. MATERIALS AND
methodsA single-blinded two-armed randomized control trial with 1:1 parallel allocation carried out from 2016 to 2020 in a single center. The follow-up period was 30 days. Compared interventions involved extracorporeal and intracorporeal ileocolic anastomosis in laparoscopic right hemicolectomy. The main outcome of the study was bowel recovery measured as the time to the first stool. Other outcomes involved the time to the first flatus, morbidity, and duration of surgery.
resultsOne hundred and seventeen patients undergoing a laparoscopic right hemicolectomy with curative intent were eligible for the trial. Eight patients refused to participate. One hundred and two patients were analyzed, 52 in the intracorporeal group and 50 in the extracorporeal group. The groups did not differ in terms of cancer stage or body mass index, but did differ in age and sex. Intracorporeal anastomosis was associated with a shorter time to the first stool than extracorporeal, 32.8 h (26.0-43.7) vs. 41.7 (35.9-50.0), p = 0.017. There was no significant difference in the time to the first flatus, 30 h (23.2-42.3) vs. 26.6 h (21.8-37.3), p = 0.165. Similarly, overall complications did not differ (EC 12/50 vs. IC 10/52, p = 0.56). There were no differences in length of surgery, 190 min (150-230) and 190 min (180-220), p = 0.55.
conclusionIntracorporeal ileocolic anastomosis following laparoscopic right hemicolectomy results in slightly faster bowel recovery, with no differences in morbidity and duration of surgery.
