Methods:
For the patients who received ERCP at Inha University Hospital from Jan. 2001 to Dec. 2007, we retrospectively analyzed the clinical manifestations, the treatment and the clinical outcomes of the cases with duodenal perforation.
Results:
Among the 1708 ERCP cases, duodenal perforation occurred in eleven (0.6%) patients. There were two cases of duodenal perforations (type I), four cases of peri-Vaterian injury (type II), two cases of bile duct perforations (type III) and three cases of retroperitoneal perforations (type IV). Six patients (55%) were treated surgically while the others were managed conservatively. Except for one death (9.1%), ten patients fully recovered. Either residual diseases or fluid collections, as seen on CT, were present in the surgically managed patients. The median time interval between ERCP and surgery was 19 hours (range: 8∼30 hours).

Conclusions:
To decide on the management of duodenal perforation after ERCP, the presence of residual disease or the leakage of intraluminal contents should be considered along with the type of the perforation. (Korean J Gastrointest Endosc 2011;42:83-89)
