BACKGROUND: The aim of the present study was to evaluate the usefulness of a single-balloon enteroscope (SBE) including a newly developed short SBE (SIF-Y0004) for therapeutic endoscopic retrograde cholangiography (ERC) in patients with Roux-en-Y (R-Y) anastomosis.

PATIENTS AND METHODS: Therapeutic ERC using a SBE was attempted in 19 cases (41 procedures) with R-Y anastomosis after gastrectomy. A standard SBE (working length of 200 cm, working channel of 2.8 mm) was used in 11 cases (Group L), and a short SBE (working length of 152 cm, working channel of 3.2 mm) was used in eight cases (Group S).

RESULTS: Insertion of the scope up to the major papilla was achieved in 79% (15/19) of cases. Average insertion time was 37.0 ± 13.8 min (range, 19-62 min). Bile duct cannulation rate was 79% (11/14) after exclusion of the initial case in which scope exchange was unsuccessful. Average procedure time was78.8 ± 26.9 min (18-119 min). The scheduled therapeutic procedure was completed in 67% (10/15) of the cases (53% [10/19] on an intention-to-treat basis). Cardiorespiratory suppression due to sedative agents resulting in scope withdrawal developed in one procedure (2.4%; 1/41). Although there was no significant difference in therapeutic results between the two groups, the number of procedures was smaller (1.8 ± 1.3 vs 3.6 ± 3.1; P = 0.286) in Group S than in Group L.

CONCLUSIONS: Therapeutic ERC using a SBE for patients with R-Y anastomosis is considered to be safe and effective. A short SBE appears to be promising for further improvement in therapeutic results.
