1 · What the graph read from 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.

2 · The registry

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 current standard treatment for external rectal prolapse and symptomatic high-grade internal rectal prolapse is surgical correction with minimally invasive ventral mesh rectopexy using either laparoscopy or robotic assistance. This study examines the number of procedures needed to complete the learning curve for robot-assisted ventral mesh rectopexy (RVMR) and reach adequate performance.

methodsA retrospective analysis of all primary RVMR from 2011 to 2019 performed in a tertiary pelvic floor clinic by two colorectal surgeons (A and B) was performed. Both surgeons had previous experience with laparoscopic rectopexy, but no robotic experience. Skin-to-skin operating times (OT) were assessed using LC-CUSUM analyses. Intraoperative and postoperative complications were analyzed using CUSUM analyses.

resultsA total of 182 (surgeon A) and 91 (surgeon B) RVMRs were performed in total. There were no relevant differences in patient characteristics between the two surgeons. Median OT was 75 min (range 46-155; surgeon A) and 90 min (range 63-139; surgeon B). The learning curve regarding OT was completed after 36 procedures for surgeon A and 55 procedures for surgeon B. Both before and after completion of the learning curve, intraoperative and postoperative complication rates remained below a predefined acceptable level of performance.

conclusions36 to 55 procedures are required to complete the learning curve for RVMR. The implementation of robotic surgery does not inflict any additional risks on patients at the beginning of a surgeon's learning curve.
