Dual-operator thin endoscope combination surgery for endoscopic submucosal dissection of gastrointestinal epithelial neoplasms: a single-center retrospective pilot study.

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
backgroundThin endoscope combination surgery (TECS) is a dual-operator technique using two identical thin therapeutic endoscopes to enable dynamic traction and task sharing during advanced endoscopic treatment. This study aimed to evaluate the feasibility, safety, and procedural characteristics of TECS in clinical practice and characterize the learning curve for a fixed operator-assistant team adopting this approach.
methodsWe retrospectively analyzed the data of consecutive patients who underwent TECS for gastrointestinal epithelial tumors between January and December 2024. The primary outcome was technical success without conversion. Secondary outcomes included en bloc and R0 resection, treatment time, resection speed, and adverse events (AEs; captured during hospitalization and within 30 days).
resultsForty-five patients were enrolled; one was excluded for inadequate sedation, leaving 44 eligible. TECS was completed in 43 cases (26 gastric, 17 colorectal); 41 epithelial neoplasms were included in efficacy analyses. En bloc and R0 resection were achieved in all neoplastic cases. No intra- or delayed AEs occurred in the 43 completed procedures (0/43; two-sided 95% confidence interval [CI], 0.0-8.2). In a learning-curve subset performed by a fixed operator-assistant team (n = 32), median treatment time decreased from 59 to 27 min (p = 0.003), and median resection speed increased from 20.9 to 48.4 mm
conclusionsTECS was feasible and safe in this pilot series, enabling continuously adjustable, bidirectional traction and task sharing. Prospective multicenter studies are warranted to validate indications, safety, reproducibility, and cost-effectiveness.
