The usefulness of the endoscopic surgical skill qualification system in laparoscopic right hemicolectomy: a single-center, retrospective analysis with propensity score matching.
Article in Langenbeck's archives of surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. An erratum has been issued. Cited by 3 papers.
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
purposeRecently, a new certification system called the Endoscopic Surgical Skill Qualification System (ESSQS) has been launched in Japan to improve surgical safety. This study aimed to determine whether ESSQS-qualified surgeons affect the short- and long-term outcomes of laparoscopic right hemicolectomy.
methodsA total of 187 colon cancer patients who underwent laparoscopic right hemicolectomy at Kindai University Hospital between January 2016 and December 2020 were enrolled. These patients were divided into two groups based on surgeries performed by ESSQS-qualified surgeons (QS group) and non-ESSQS-qualified surgeons (NQS group). The short- and long-term outcomes were compared between the two groups before and after propensity score matching (PSM).
resultsAfter PSM, 43 patients from each group were included in the matched cohort. In the short-term outcomes, the total operative time was significantly longer in the NQS group than in the QS group (229 vs. 174 min, p < 0.0001). However, there were no significant differences in the two groups regarding blood loss (0 vs. 0 ml, p = 0.7126), conversion (0.0% vs. 7.0%, p = 0.0779), Clavien-Dindo ≥ 2 complications (9.3% vs. 7.0%, p = 0.6933), mortality (2.3% vs. 0.0%, p = 0.3145), and postoperative hospital stay (9 vs. 9 days, p = 0.5357). In the long-term outcomes, there were no significant differences between the two groups in the 3-year overall survival (86.6% vs. 83.0%, p = 0.8361) and recurrence-free survival (61.7% vs. 72.0%, p = 0.3394).
conclusionLaparoscopic right hemicolectomy performed by ESSQS-qualified surgeons contributed to shorter operative time. Under the supervision of ESSQS-qualified surgeons, almost equivalent safety and oncological outcomes are expected even in surgeries performed by non-ESSQS-qualified surgeons.
