Abstract: | INTRODUCTION: The pathogenesis of idiopathic pancreatitis (IP) remains poorly understood. Our hypothesis is that IP is a sequel of the microcrystallisation of hepatic bile. AIMS AND METHODS: A prospective case–control study compared 55 patients (symptomatic cholelithiasis, 30: 14 men, 16 women, median age 36 years, body mass index (BMI) 25.1 ¡ 0.33 kg/m2 ; gallstone pancreatitis, nine: six women, three men, median age 35 years, BMI 24.86 ¡ 0.23 kg/m2 ; and idiopathic pancreatitis, 16: seven women, nine men, median age 34 years, BMI 23.34 ¡ 0.2 kg/m2 ) with 30 controls (15 men, 15 women, median age 38 years, BMI 24.5 ¡ 0.23 kg/m2 , undergoing laparotomy and who had normal gallbladder and no demonstrable stones on ultrasonography). Ultrafiltered bile from the common hepatic duct in patients and controls was anaerobically incubated and examined by polarised light microscopy, for nucleation time (NT). Ethical approval was obtained. RESULTS: Patients were similar to controls. Mean NT in all groups of patients was significantly shorter than controls (established gallstones cumulative mean NT, 1.73 ¡ 0.2 vs controls, 12.74 ¡ 0.4 days vs, p = 0.001, t test and IP patients mean NT, 3.1 ¡ 0.24 days vs controls, 12.74 ¡ 0.4 days, p = 0.001, t test). However, NT in those with IP was significantly longer compared with those with established gallstones (mean NT in IP, 3.1 ¡ 0.24 SEM days, vs cumulative mean in patients with established symptomatic gallstones, 1.73 ¡ 0.2 days, p = 0.002, t test). CONCLUSION: NT in bile in patients with IP is abnormal and is intermediate in NT of lithogenic and non-lithogenic bile. |
