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

backgroundSince the introduction of powered circular staplers in colorectal surgery, there has been growing interest in their impact on reducing complications, particularly anastomotic leakage. This study compared short-term postoperative outcomes between powered and manual circular staplers.

methodsThis retrospective study included colorectal cancer patients at the tertiary referral center from April to October 2023 who underwent anterior or low anterior resection (LAR) using a circular stapler. According to energy source, patients were divided into powered and manual groups, which used two powered and four types of manual staplers, respectively. All open, laparoscopic, and robotic approaches were included. Propensity score matching (PSM) analysis was used to reduce selection bias. Postoperative complications within 30 days, especially for anastomosis-related complications, were compared between the groups.

resultsAmong 511 patients, the powered group was 161 (32%). After PSM, 143 pairs of 286 patients were analyzed. The proportions of LAR were 53.8% and 51.0%, and initial diverting stoma rates were 23.1% and 22.4% for the Powered and Manual groups, respectively. Comprehensive complication rates were similar between the Powered group and the Manual group, without statistical significance (13.3% vs. 21.0%, P = 0.063). Anastomotic leakage was not different between the Powered and Manual groups (4.2% vs. 4.9%, P = 0.782). There was no significant difference in other complications, including anastomotic bleeding, ileus, surgical site infection, and intra-abdominal hematoma.

conclusionsThe study implies that powered circular staplers may not significantly reduce postoperative complications, including anastomotic leakages, compared to manual staplers in colorectal surgery of high-volume centers.
