OBJECTIVE: Endoscopic retrograde cholangiopancreatography (ERCP) in post-Billroth II (BII) gastrectomy is more difficult due to anatomical changes. The difficulties include entrance to the afferent loop and selective cannulation. Our aim here is to report the success rate and special manipulations and techniques of this procedure.
METHODS: A retrospective review of 56 ERCP procedures in post-BII gastrectomy patients was performed. There were 43 male and 13 female patients with a mean age of 63 yr (range, 32-78 yr). All cases were tried with forward-viewing endoscope first. Of the failed cases, 10 were retried by side-view duodenoscope. The entrance to the afferent loop was attempted by starting from the upper opening at the anastomosis site and, if this failed, then using the lower opening; presence of bile; and air-contrasted afferent loop under fluoroscopy. If failure of afferent loop entrance resulted, hand compression over the mid-abdomen, or polypectomy snare in the working channel of the endoscope, was tried. For failure of common bile duct cannulation with straight catheters, techniques of pushing the catheter against the duodenal wall and bending the tip of the endoscope or guidewire were used.
RESULTS: The success rate of afferent loop entrance was 76.7% (43 of 56 cases). The afferent loop was identified in the upper orifice of the anastomosis in 93% (40 of 43) of the cases. Eight cases of afferent loop entrance could be facilitated by hand compression, and three by polypectomy snare in the working channel of the endoscope. The success rate of ERCP cannulation in those successful afferent loop intubation cases was 81.3% (35/43 cases). Most of the selective common bile duct (CBD) cannulation was achieved by straight (new) catheter and an additional six cases were successful using the techniques mentioned. No serious complications were encountered, except three cases of submucosal hemorrhage.
CONCLUSION: The overall success rate of BII ERCP was 62.5% (35 of 56 cases). The special manipulations mentioned in BII ERCP can be helpful in certain cases.
