Background: Recently, with the advent of more advanced devices and endoscopic techniques, endoscopic retrograde cholangiopancreatography (ERCP) in Billroth II (B-II) patients has been increasingly performed. However, the procedures are difficult, and the techniques and strategies have not been defined.
Aim: To reveal the appropriate scope for ERCP in B-II patients.
Methods: Sixty ERCP procedures were performed on B-II patients between June 2005 and May 2018 at Fukushima Medical University Hospital, and in 44 cases, this was the first ERCP procedure performed by esophagogastroduodenoscopy (EGDS) or colonoscopy (CS) after B-II gastrectomy. These cases were divided into two groups: 17 cases of ERCP performed by EGDS (EGDS group) and 27 cases of ERCP performed by CS (CS group). The patient characteristics and ERCP procedures were compared between the EGDS and CS groups.
Results: The procedural time was significantly shorter in the EGDS group than in the CS group [median (range): 60 (20-100) vs 90 (40-128) min, P value < 0.01]. CS was an independent factor of a longer ERCP procedural time according to the univariate and multivariate analyses (odds ratio: 3.97, 95%CI: 1.05-15.0, P value = 0.04).
Conclusion: Compared to CS, EGDS shortened the procedural time of ERCP in B-II patients.
