Consensus for endoscopic retrograde cholangiopancreatography (ERCP) related perforation management is lacking. We aimed to identify candidate patients for conservative management by examining treatment results and to introduce a simple, algorithm-based management guideline.
A retrospective review of 53 patients with ERCP-related perforation between 2000 and 2010 was conducted. Data on perforation site (duodenum lateral wall or jejunum, type I; para-Vaterian, type II), management method, complication, mortality, hospital stay, and hospital cost were reviewed. Comparative analysis was done according to the injury types and management methods.
The outcome was greater
in the conservative group than the operative group with shorter hospital stay (20.6 days vs. 29.8 days, P = 0.092), less cost (10.6 thousand United States Dollars [USD] vs. 19.9 thousand USD, P = 0.095), and lower morbidity rate (22.9% vs. 55.6%, P = 0.017). Eighty-one percent (17/21) of type I injuries were operatively managed and 96.9% (31/32) of type II injuries were conservatively managed. Between the types, type II showed better results over type I with shorter hospital stay (19.3 days vs. 30.6 days, P = 0.010), less cost (9.5 thousand USD vs. 20.1 thousand USD, P = 0.028), and lower complication rate (18.8% vs. 57.1%, P = 0.004). There was no difference in mortality.
Type II injuries were conservatively manageable and demonstrated better outcomes than type I injuries. The management algorithm suggests conservative management in type II injuries without severe peritonitis or unsolved problem requires immediate surgical correction, including operative management in type I injuries unless endoscopic intervention is possible. Conservative management offers socio-medical benefits. Conservative management is recommended in well-selected patients.
