  • Title: Effect of the diameter of the common bile duct on the incidence of bile duct stones in patients with recurrent attacks of right epigastric pain after cholecystectomy.
    Author: Grönroos JM, Haapamäki MM, Gullichsen R.
    Journal: Eur J Surg; 2001 Oct; 167(10):767-9. PubMed ID: 11775729.
    Abstract:
    OBJECTIVE: To study the relationship between the diameter of the common bile duct and the incidence of bile duct stones in non-jaundiced patients with recurrent attacks of right epigastric pain after cholecystectomy. DESIGN: Retrospective study. SETTING: University hospital, Finland. SUBJECTS: 57 consecutive, non-jaundiced patients admitted for elective endoscopic retrograde cholangiopancreatography (ERCP) because of attacks of right epigastric pain after cholecystectomy. INTERVENTIONS: Measurement of maximum diameter of the common bile duct and presence or absence of bile duct stones. MAIN OUTCOME MEASURES: Diameter of bile duct (10 mm or less was regarded as normal) and presence or absence of stones. RESULTS: 33 patients had normal-sized bile ducts and in 24 they were widened. Only 2/33 patients with normal-sized ducts (6%) had stones, compared with 11/24 (46%) with wide ducts (p = 0.0008). However, the degree of ductal dilatation did not seem to have any influence on the presence or absence of stones. CONCLUSION: Bile duct stones are unlikely after cholecystectomy in patients who are not jaundiced and have a normal-sized common bile duct. However, nearly half of the patients with a wide common bile duct had stones, but the degree of dilatation was not important.
