New diagnostic methods of endoscopic retrograde cholangiopancreatography using a balloon catheter (balloon ERCP) and endoscopic Oddi's sphincter manometry were employed and investigated in 31 patients with an anomalous pancreaticobiliary junction (APBJ). Balloon ERCP was more comfortable for the patients and provided better visualization than conventional ERCP because this procedure allows free postural movement due to withdrawal of the duodenoscope and provides for an additional injection of contrast medium, if necessary. Endoscopic manometric study demonstrated that 1) although the patients with APBJ had a longer common channel, the length of the Oddi's sphincter segment showing phasic wave activity was not different from that of the controls, 2) the anomalous junction was located beyond the Oddi's sphincter segment and showed no phasic wave activity. These findings suggest that contractions of Oddi's sphincter in patients with APBJ may contribute to reflux between the pancreatic and bile ducts, leading to various pathologic conditions associated with this anomaly. Our balloon ERCP and manometric Oddi's sphincter study demonstrated new diagnostic means for determining morphological and functional aspects of APBJ. (Dig Endosc 1996 ; 8 : 205‐208)
