Meta‑analysis of randomized controlled trials comparing intracorporeal versus extracorporeal anastomosis in minimally invasive right hemicolectomy: upgrading the level of evidence.
Synthesis in International journal of colorectal disease, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 28 papers, 2 of them syntheses that pooled it.
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
backgroundMinimally invasive right hemicolectomy has been increasingly used for the treatment of right hemicolectomy disease, and both intracorporeal anastomosis (ICA) and extracorporeal anastomosis (ECA) are available to restore intestinal continuity. However, the advantages and disadvantages of these two anastomoses are highly controversial. The present meta-analysis evaluated the effectiveness of ICA versus ECA in minimally invasive right colectomy to improve the grade of evidence.
methodsWe searched the PubMed, Embase, Cochrane Library, and Web of Science databases for randomized controlled trials (RCTs) comparing intracorporeal versus extracorporeal anastomosis in laparoscopic or robotic right hemicolectomy published from database inception to February 2023. Two researchers performed the literature review, data extraction, bias assessment, and meta-analysis of the data using Review Manager 5.4 software.
resultsSeven RCTs with a total of 750 patients were included in the meta-analysis. The results showed a lower incidence of postoperative paralytic ileus (RR 0.62, 95% CI 0.39 ~ 0.99, p = 0.04) and shorter incision length (MD - 1.38; 95% CI: - 1.98 ~ - 0.78, p < 0.00001), but longer operative time (MD 10.69; 95% CI: 2.76 ~ 18.63, p = 0.008). The remaining events including bleeding (RR 0.49, 95% CI: 0.12 ~ 2.04, p = 0.33), anastomotic leak (RR 0.62, 95% CI: 0.39 ~ 0.99, p = 0.85), surgical site infection (RR 0.15, 95% CI: 0.22 ~ 1.25, p = 0.15), overall perioperative morbidity (RR 0.86, 95% CI: 0.58 ~ 1.26, p = 0.44), number of harvested lymph nodes (MD 0.75; 95% CI: - 0.15 ~ 1.65, p = 0.10), and length of hospital stay (MD - 0.27; 95% CI: - 0.91 ~ 0.38, p = 0.42) were not statistically significant.
conclusionsCompared to ECA, ICA in minimally invasive right hemicolectomy reduced the risk of postoperative paralytic ileus and shortened the length of the incision but prolonged the operative time.
