Recovery after intracorporeal anastomosis in laparoscopic right hemicolectomy: a systematic review and meta-analysis.
Synthesis in Langenbeck's archives of surgery, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 43 papers, 7 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
purposeAlthough intracorporeal anastomosis (IA) appears to guarantee a faster recovery compared to extracorporeal anastomosis (EA), the data are still unclear. Thus, we performed a systematic review of the literature with meta-analysis to evaluate the recovery benefits of intracorporeal anastomosis. MATERIALS AND
methodsA systematic search was performed in electronic databases (PubMed, Web of Science, Scopus, EMBASE) using the following search terms in all possible combinations: "laparoscopic," "right hemicolectomy," "right colectomy," "intracorporeal," "extracorporeal," and "anastomosis." According to the pre-specified protocol, all studies evaluating the impact of choice of intra- or extracorporeal anastomosis after right hemicolectomy on time to first flatus and stools, hospital stay, and postoperative complications according to Clavien-Dindo classification were included.
resultsSixteen articles were included in the final analysis, including 1862 patients who had undergone right hemicolectomy: 950 cases (IA) and 912 controls (EA). Patients who underwent IA reported a significantly shorter time to first flatus (MD = - 0.445, p = 0.013, Z = - 2.494, 95% CI - 0.795, 0.095), to first stools (MD = - 0.684, p < 0.001, Z = - 4.597, 95% CI - 0.976, 0.392), and a shorter hospital stay (MD = - 0.782, p < 0.001, Z = -3.867, 95% CI - 1.178, - 0.385) than those who underwent EA. No statistically significant differences in complications between the IA and EA patients were observed in the Clavien-Dindo I-II group (RD = - 0.014, p = 0.797, Z = - 0.257, 95% CI - 0.117, 0.090, number needed to treat (NNT) 74) or in the Clavien-Dindo IV-V (RD = - 0.005, p = 0.361, Z = - 0.933, 95% CI - 0.017, 0.006, NNT 184). The IA procedure led to fewer complications in the Clavien-Dindo III group (RD = - 0.041, p = 0.006, Z = - 2.731, 95% CI - 0.070, 0.012, NNT 24).
conclusionsAlthough intracorporeal anastomosis appears to be safe in terms of postoperative complications and is potentially more effective in terms of recovery after surgery, further ad hoc randomized clinical trials are needed, given the heterogeneity of the data available in the current literature.
