The Management of Dysfunctional Gallbladder Disease and the Role of Laparoscopic Cholecystectomy on Symptom Improvement: A Retrospective Cohort Study.

Background Biliary dyskinesia (BD) is a disorder characterised by abdominal pain of biliary origin (i.e., sudden steady pain at the right upper quadrant of the abdomen or the epigastrium, the absence of gallstones on ultrasound (US)), and a decreased gallbladder ejection fraction (GBEF) on a cholecystokinin-cholescintigraphy hepatobiliary iminodiacetic acid (CCK-HIDA) scan. Patients experiencing symptoms suggestive of biliary obstruction, but lacking gallstones, yet exhibiting abnormal gallbladder emptying, may find therapeutic benefit from laparoscopic cholecystectomy. Common symptoms include recurrent, intense, and enduring pain, often exacerbated by fatty food consumption, localised in the upper right quadrant or epigastric region. This pain may radiate to the back or shoulder, persisting for at least 30 minutes but not exceeding several hours, and it is sometimes accompanied by nausea and vomiting. Abnormal gallbladder emptying is typically indicated by a GBEF below 35% on cholescintigraphy following cholecystokinin administration. Objective This study represents a single-centric review focusing on 88 patients over a five-year period who presented with features of dysfunctional gallbladder and underwent cholescintigraphy. The primary aim was to identify whether there is any role for laparoscopic cholecystectomy in symptom improvement among these patients. Methods This was a retrospective cohort study involving data collection using electronic medical records. Eighty-eight patients who underwent the HIDA scan between January 2019 and December 2023 at Wirral University Teaching Hospital NHS Foundation Trust (WUTH) were identified and separated into two groups, either hypofunctioning gallbladder (EF<35% ) or hyperfunctioning gallbladder (EF>80%). Normal HIDA scan patients (EF between 35%-80%) were excluded. The frequency of laparoscopic cholecystectomy and subsequent symptom improvement were recorded. Results Fifty-one patients were diagnosed with gallbladder dyskinesia (BD). Of these, 36 patients (30 females, mean age 43) were diagnosed with hypofunctional gallbladder (EF<35%), where 17 patients underwent laparoscopic cholecystectomy, resulting in symptom improvement in 10 patients (58.8%). Conversely, 15 patients were diagnosed with hyperfunctional gallbladder (13 females, mean age 48.6). Only two patients (13%) underwent laparoscopic cholecystectomy with 100% symptom improvement in both patients. Conclusions In conclusion, our retrospective study highlights the significance of the HIDA scan in identifying gallbladder hypofunction among patients presenting with biliary symptoms. The findings establish the efficacy of laparoscopic cholecystectomy as a management approach, with a notable proportion of patients experiencing symptom improvement (58.8%). These results contribute to our understanding of biliary dysfunction management and emphasise the importance of individualised treatment strategies for optimal patient outcomes. Further, randomised controlled trials (RCTs) are warranted to validate these findings and explore additional factors influencing symptom resolution in this patient population.
