In patients with Roux-en-Y hepaticojejunostomy (HJ), endoscopic retrograde cholangiography (ERC) cannot usually be achieved since the anastomosis is not reachable via standard duodenoscope. In this study, we report our experience with ERC using double balloon enteroscope (DBE) (DBE-ERC) in patients with HJ.
The DBE-ERC procedures performed since the index case done dated May 3, 2006 have been overviewed.
Fourteen patients underwent the procedure. DBE-ERC was successful in all but one patient, for whom the anastomosis could not be reached (success rate to reach anastomosis: 92.9%). The remaining 13 patients (7 female, 6 male; age 28–61 years, mean 45.3 years) had 20 sessions of DBE-ERC. The cannulation of the bile duct was achieved in all patients. The procedures, such as sphincteroplasty, dilatation, stone extraction and stent placement, were performed. Therapeutic procedures were all successful, except for in a single patient, who had the common bile duct filled with multiple stones and was referred for surgery. Three patients who had anastomotic stenosis treated by stenting are symptom free on follow-up at 3, 9 and 12 months, respectively, after stent removal. Retroperitoneal air was detected in a patient following stricturoplasty, but recovery was attained with medical treatment alone. Mean duration of the procedures was 75 ± 62 min.
DBE-ERCP enables us to perform ERC in a group of patients for whom it was impossible previously. Further experience is needed to evaluate its therapeutic efficacy compared with alternative methods.
