Development of expert consensus protocols for diagnostic and procedural use of the EndoFLIP system.
Article in Surgical endoscopy, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 AND STUDY
aimThe EndoFLIP system is currently the only available impedance planimetry system, providing real-time, detailed information on the diameter, luminal area, distensibility, and compliance of the esophagogastric junction (EGJ), along with its 2D representation. EndoFLIP can support diagnosis and provide physiological feedback to potentially guide interventions for structural and functional gastroesophageal disorders. However, the lack of standardized usage protocols complicates the interpretation and comparability of results. This paper aims to establish a consensus on protocols to standardize the use of the EndoFLIP system in both diagnostic and intraoperative settings, so as to ensure consistent application across varied clinical and scientific settings.
methodsA multidisciplinary European Advisory Board (AB) comprising eight gastroenterologists and surgeons with extensive experience in EndoFLIP use undertook a structured international expert consensus process. Following a systematic literature review and a face-to-face expert meeting, candidate statements were developed and independently rated using an electronic survey. Consensus was predefined as ≥ 75% agreement ('agree' or 'strongly agree'), whereas statements requiring neutral responses to achieve this threshold were classified as weak consensus. A final expert meeting was convened to review the results and ratify the recommendations.
resultsStandardized protocols for obtaining EndoFLIP measurements in preoperative/diagnostic and intraoperative settings were developed. The statements forming the protocols (25 related to diagnostic use and 20 to intraoperative measurements) were voted on by the AB panel, with consensus reached for all statements.
conclusionsEndoFLIP has demonstrated great potential in complementing endoscopy for diagnosing achalasia and providing intraoperative guidance for treating achalasia and gastroesophageal reflux disease. The implementation of the developed standardized protocols in real-world settings is essential to validate them, as it will enable the collection of consistent data on the pre- and intraoperative use of EndoFLIP, facilitate its routine use, and better define patient pathways.
