BACKGROUND: Post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) is more common in patients with asymptomatic common bile duct stones (CBDSs) and normal anatomy than in those with symptomatic CBDS; however, studies on the effect of surgically altered anatomy are lacking. We aimed to investigate whether asymptomatic CBDS in balloon enteroscopy-assisted ERCP cases for surgically altered anatomy also has a high incidence of PEP and analyze the risk factors for PEP.
METHODS: We retrospectively analyzed 108 consecutive patients who underwent initial ERCP for CBDS with surgically altered anatomies and with naive papilla at Kitasato University Hospital from April 2015 to December 2022.
RESULTS: Study participants were as follows: 92 (85%) patients with symptomatic CBDS and 16 (15%) patients asymptomatic CBDS. The overall bile duct cannulation success rate was 89.8%, with PEP occurring in 7.4% of patients (symptomatic CBDS: 3.3%, asymptomatic CBDS: 31.3%). PEP incidence was significantly higher for asymptomatic CBDS (p = .0017). Multivariate analysis identified asymptomatic CBDS and precut sphincterotomy as significant risk factors for PEP.
CONCLUSIONS: Asymptomatic CBDS may be a risk factor for PEP onset in balloon enteroscopy-assisted ERCP with surgically altered anatomy. Therefore, the procedure should be performed after obtaining sufficient informed consent and adequate preparation.
