Abstract
Abstract Background Biliary dyskinesia (BD) is a benign disorder characterized by recurrent episodes of biliary pain in the absence of gallstones on ultrasound, normal liver function tests and an ejection fraction (EF) of <35% on hepatobiliary iminodiacetic acid (HIDA) scan. Laparoscopic cholecystectomy (LC) remains the only known effective treatment for BD. However, many surgeons are reluctant to offer LC in such patients due to the fear of non-resolution of symptoms. Our aim was to analyse the outcome of patients who underwent LC for BD in terms of resolution of the biliary symptoms. Methods Multicentre retrospective cohort study of patients who have BD proven on HIDA scan from January 2015 to December 2022. BD was defined as EF ≤35% on HIDA scan. Those with EF ≤35% but had evidence of gallstones, microlithiasis or post op leak were excluded from the study. Electronic case notes were reviewed for demographic details, duration of symptoms, body mass index (BMI), liver function test (LFT), radiological investigations, endoscopy report and histopathology results of cholecystectomy. Rome IV criteria of functional gastrointestinal (GI) disorders was used to confirm symptoms were biliary in origin. Results Of the 222 patients who had HIDA scan, 35 (15.7%) patients had BD. 26 (74.2%) were female and median age was 42 years (IQR 33-55). Median time from the onset of symptoms and HIDA scan was 18 months. 19 (54.2%) patients had LC preformed, 9 (25.7%) were discharged with decision of LC not required, 4 (11.4 %) had no further review and 2 (5.7%) still having LC under consideration. Histopathology of LC was, chronic inflammation in 10 (52.6%), cholesterosis in 3 (15.8%) and 4 (20.1%) had normal gallbladder. 13 (68.4%) patients who underwent LC were symptom free 12 months post-surgery. Conclusions BD although painful and potentially lifestyle limiting, does not progress to more serious consequences if untreated. Diagnosis is usually difficult, and patients go through extensive investigations before they have HIDA scan. LC improves the symptoms in two thirds of patients and should be offered to all patients with BD with appropriate counselling.
