Modified Hepatobiliary Scintigraphy for the Diagnosis of Bile Reflux in One-Anastomosis Gastric Bypass Surgery: a Prospective Multicenter Study.
Article in Obesity surgery, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 papers.
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
purposeOne-anastomosis gastric bypass (OAGB) is a relatively simple surgical procedure for those afflicted with severe obesity. Studies reported symptomatic biliary reflux gastritis and esophagitis as predominant complications. Hepatobiliary scintigraphy (HIDA) is the least invasive test for the diagnosis of bile reflux, with good sensitivity, patient tolerability, and reproducibility. The aim of this study was to define an optimized HIDA scintigraphy protocol for demonstrating bile reflux in post-OAGB patients. MATERIAL AND
methodsWe conducted a prospective multicenter study. Patients after OAGB with dyspeptic complaints were included. All patients underwent HIDA scan with a dedicated protocol for demonstrating bile reflux; prevalence and severity were reported.
resultsNineteen patients were included, 18 females and one male, with mean age of 41.8 years and mean time of 22.4 months from operation to the scan. Bile reflux into the gastric pouch was documented in 11 patients (53%). Reflux to the stomach pouch was severe in three patients (27%), moderate in two patients (18%), and mild in six patients (55%). Bile reflux into the esophagus was documented in four patients (21%), severe reflux in one patient (25%), and mild in the other three (75%). A correlation was found between complaints of vomiting, heartburn and regurgitation, and findings of esophagitis on gastroscopy in patients with vs. without reflux.
conclusionsThe tailored HIDA scan protocol detected bile reflux in more than half of the post-OAGB patients included in the study, with a high diagnostic sensitivity.
