Intraoperative FLIP to guide revisional hiatal hernia repair: early experience and outcomes.
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
backgroundRevisional hiatal hernia repair (rHHR) represents a challenge in foregut surgery, given scarring, distorted anatomy, and high risk of morbidity. Traditional methods of intraoperative assessment, such as bougie calibration and endoscopic inspection, are subjective and lack physiologic correlation. The functional luminal imaging probe (FLIP) offers objective, real-time assessment of esophagogastric junction (EGJ) diameter, distensibility, and cross-sectional area. This study evaluates the utility of intraoperative FLIP to guide surgical decision-making and assess outcomes in a cohort of complex patients undergoing rHHR.
methodsA retrospective review was conducted evaluating patients who underwent FLIP-guided rHHR from 2020 to 2025 at an urban safety-net hospital. Intraoperative FLIP measurements, specifically the diameter (D) and distensibility index (DI), were used to tailor surgical management, including decisions to take down, preserve, or alter the fundoplication. Longitudinal follow-up assessed symptom resolution and quality of life (QOL) using the GERD-Health-Related Quality of Life (GERD-HRQL) questionnaire.
resultsA total of 17 patients undergoing 18 revisional operations were analyzed (mean age 47.5 years; 88% female). Intraoperative FLIP values prompted a change in surgical management in 61% (11/18) of cases. Modifications included preservation of prior fundoplication (36%), tightening an existing fundoplication (27%), deferral of fundoplication (27%), and changing fundoplication type (9%). At a mean follow-up of 24.9 months, GERD-HRQL scores improved from 26.7 ± 8.5 preoperatively to 16.5 ± 12.9 postoperatively (p = 0.034). At long-term follow-up (mean 38.8 months), persistent symptoms were noted, including reflux requiring medication (70.6%) and dysphagia (35.3%), though 64.7% of symptomatic patients were managed nonoperatively.
conclusionsFLIP-guided revisional HHR facilitates a tailored surgical approach, prompting alterations in management based on objective physiologic data. While clinically meaningful improvements in quality of life were observed, the persistence of symptoms in this high-risk population highlights the intrinsic complexity of revisional foregut surgery and the need for future prospective studies.
