Functional Dyspepsia and Irritable Bowel Syndrome are Highly Prevalent in Patients With Gallstones and Are Negatively Associated With Outcomes After Cholecystectomy: A Prospective, Multicenter, Observational Study (PERFECT - Trial).

ABSTRACT

OBJECTIVE: To determine the prevalence of FD and IBS in patients eligible for cholecystectomy and to investigate the association between presence of FD/ IBS and resolution of biliary colic and a pain-free state. SUMMARY BACKGROUND DATA More than 30% of patients with symptomatic cholecystolithiasis reports persisting pain postcholecystectomy. Coexistence of FD/IBS may contribute to this unsatisfactory outcome. METHODS: We conducted a multicenter, prospective, observational study (PERFECT-trial). Patients ≥18 years with abdominal pain and gallstones were included at 5 surgical outpatient clinics between 01/2018 and 04/2019. Follow-up was 6 months. Primary outcomes were prevalence of FD/IBS, and the difference between resolution of biliary colic and pain-free state in patients with and without FD/IBS. FD/IBS was defined by the Rome IV criteria, biliary colic by the Rome III criteria, and pain-free by an Izbicki Pain Score ≤10 and visual analogue scale ≤4. RESULTS: We included 401 patients with abdominal pain and gallstones (assumed eligible for cholecystectomy), mean age 52 years, 76% females. Of these, 34.9% fulfilled criteria for FD/IBS. 64.1% fulfilled criteria for biliary colic and 74.9% underwent cholecystectomy, with similar operation rates in patients with and without FD/IBS. Postcholecystectomy, 6.1% of patients fulfilled criteria for biliary colic, with no significant difference between those with and without FD/IBS at baseline (4.9% vs 8.6%, P = 0.22). Of all patients, 56.8% was pain-free after cholecystectomy, 40.7% of FD/IBS-group vs 64.4% of no FD/IBS-group, P < 0.001. CONCLUSIONS: One third of patients eligible for cholecystectomy fulfil criteria for FD/IBS. Biliary colic is reported by only a few patients postcholecys-tectomy, whereas nonbiliary abdominal pain persists in >40%, particularly in those with FD/IBS precholecystectomy. Clinicians should take these symptom-dependent outcomes into account in their shared decision-making process. TRIAL REGISTRATION The Netherlands Trial Register NTR-7307. Registered on 18 June 2018.
