Surgical site infection after intracorporeal and extracorporeal anastomosis in laparoscopic left colectomy for colon cancer: a multicenter propensity score-matched cohort study.
Article in Surgical endoscopy, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
backgroundIntracorporeal anastomosis (IA) is associated with reduced surgical site infection (SSI) and other postoperative complications in laparoscopic right colectomy (LRC). However, evidence is inadequate for IA in laparoscopic left colectomy (LLC). This study aimed to determine the effect of IA and extracorporeal anastomosis (EA) on SSI and other short-term postoperative complications in LLC.
methodsIn this retrospective multicenter propensity score-matched (PSM) cohort study, we enrolled consecutive patients who underwent LLC with IA (TLLC/IA) and laparoscopic-assisted left colectomy with EA (LALC/EA) at two medical centers between January 2015 and September 2021. Propensity score matching with a 1:2 ratio was employed. The primary outcome was SSI occurrence. Secondary outcomes were operating time, intraoperative hemorrhage, other postoperative complications, and pathological outcomes.
resultsOverall, 574 and 99 patients received LALC/EA and TLLC/IA, respectively. After PSM, 84 patients with TLLC/IA were matched with 141 patients with LALC/EA. Thirty patients (13.3%) patients experienced SSI (17.0% in LALC/EA vs 7.1% in TLLC/IA). IA was associated with a reduced risk of overall SSI and superficial/deep SSI compared with EA after PSM, with OR of 0.375 (95% CI, 0.147-0.959, P = 0.041). and 0.148 (95% CI, 0.034-0.648, P = 0.011), respectively. Multivariate analysis of unmatched patients indicated similar results. In the analysis of secondary outcomes, LALC/EA may have a shorter operating time (absolute mean difference - 13.41 [95% CI, - 23.76 to - 3.06], P = 0.002) and a higher risk of intraoperative hemorrhage (absolute risk difference 4.96 [95% CI, - 0.09 to 9.89], P = 0.048).
conclusionsIA in LLC is associated with a reduced risk of overall SSI and superficial/deep SSI. However, it may require a longer operating time.
