A framework for Surgical Quality Assurance (SQA) in randomized controlled trials in gastrointestinal surgery: an international Delphi consensus 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
Background: Randomized controlled trials (RCTs) in gastrointestinal surgery often lack standardized approaches to Surgical Quality Assurance (SQA), which threatens both internal and external validity. The technical complexity and inherent inter-surgeon variability in gastrointestinal procedures pose significant challenges for standardizing interventions and ensuring reproducible outcomes. SQA involves credentialing of surgeons, standardization of surgical techniques, and monitoring of performance, but consensus on essential components has been missing. To address this gap, we conducted a four-round Delphi consensus process with 40 international experts in gastrointestinal surgery and clinical trials. Methods: Experts from 15 countries were invited to rate the relevance of potential SQA items using a 5-point Likert scale from December 2023 to December 2024. The checklist was structured into three domains: credentialing, standardization of surgical techniques, and performance monitoring. Items rated as 4 ('important') or 5 ('very important') by at least 80% of experts were included in the final SQA checklist. Findings: Consensus was reached on 13 essential SQA items including a minimum annual case volume per center, a minimum surgeon case volume (overall and annually), standardized reporting guidelines, pretrial education (written materials and videos), standardization of surgical approach, standardized extent of lymphadenectomy, proctoring surgeons (without and with limited experience), periodic pathological assessment, and performance monitoring through Case Report Forms or patient file data. Interpretation: This Delphi study establishes an international expert consensus framework of 13 items for Surgical Quality Assurance in RCTs in gastrointestinal surgery. This framework is expected to be widely utilized to enhance the quality of surgical trials by improving the internal and external validity. Adoption of these standards may help strengthen the credibility, comparability, and clinical relevance of future surgical RCTs. Funding: This study received no funding.
