Purpose: Inidence of recurrent common duct stones reported approximately 20% for a second operation, and with even higher rate following subsequent reoperation. However, the factors contributing to recurrent stones have not well defined. Some authors have reported on association of juxtapapillary diverticula with recurrent biliary stones. We have studied to assess the clinical significance of coexisting PAD on recurrent common bile duct stones and to establish the rational operative procedure in primary or recurrent common duct stones with coexisting PAD.
Methods: Medical records of 456 consecutive patients (Feb. 1993∼Aug. 2002) who performed ERCP for biliary symptoms were reviewed. We comparative study retrospectively have done between patients with and without PAD on recurrence of common duct stones and outcome of treatment.
Results: Incidence of PAD was 15.1% on ERCP, and increased in the old aged patients. Incidence of biliary stone in PAD group was higher than that of non-PAD group (73.9% vs. 50.6%), and gall stone involving common duct was more prevalent in PAD group than non-PAD group. PAD group showed higher stone recurrence rate (23.5% vs. 6.1%) and earlier recurrence following conventional treatment, and needs more multiple treatments, compared with non-PAD group. Intradiverticular papillae (IDP) type showed higher stone recurrence, compared with juxtapapillary diverticula (JPD) type (36.8% vs. 15.6%).
Conclusion: PAD would be one of important contributing factors for development and recurrence of common bile duct stones. So rational operative procedure for primary or recurrent common duct stones with coexisting PAD should include extirpation of PAD, particulary in IDP type. (J Korean Surg Soc 2006;70:457-461)
