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

backgroundLaparoscopic colorectal procedures are widely adopted for colorectal cancer surgery. The double-stapling technique for circular colorectal anastomosis carries leakage rates of 11.2-13.4% and elevates stricture risk. In 2024, we introduced an innovative intracorporeal linear isoperistaltic "overlap" colorectal anastomosis; preliminary data from ten patients confirmed its safety and feasibility. This study aims to assess the feasibility and safety of the colorectal "overlap" anastomosis technique for laparoscopic and robotic surgery on a larger group of patients.

methodsAn observational study was conducted from 2023 to 2025. A total of 100 patients with adenocarcinoma of the distal sigmoid colon, rectosigmoid junction, or upper rectum underwent laparoscopic or robotic colorectal surgery with intracorporeal "overlap" colorectal anastomosis. Demographic, intraoperative, and postoperative data, including complications, length of hospital stay, and 30-day readmission rates, were analyzed. Colonoscopy at 6 months assessed anastomosis configuration and patency.

resultsThe intracorporeal linear "overlap" colorectal anastomosis was performed in 100 patients (51 laparoscopic, 49 robotic-da Vinci Xi). Mean age was 67.0 ± 10.1 years and median body mass index (BMI) 26.9 kg/m

conclusionsThe novel intracorporeal linear "overlap" colorectal anastomosis is safe and feasible and may be recommended as a reliable alternative to the conventional circular anastomosis in both laparoscopic and robotic colorectal surgery.
