Abstract
- 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.
