BACKGROUND: Few studies have reported the outcomes of self-expandable metal stent (SEMS) placement for malignant biliary obstruction in patients with surgically altered anatomy.
AIMS: To evaluate the outcomes of biliary metal stent placement with the use of a short-type single-balloon enteroscope (working length, 1520 mm; channel diameter, 3.2 mm) in such patients.
METHODS: We retrospectively studied 13 malignant biliary obstructions treated by SEMS placement. Technical success rate, functional success rate, time to recurrent biliary obstruction (RBO), and complications were evaluated.
RESULTS: Technical success rate was 100 % (13/13), functional success rate was 92 % (12/13), and the median time to RBO was 247 days (95 % CI 205.6-285.5). Complications comprised mild pancreatitis in one patient. Uncovered SEMSs were placed in three obstructions, partially covered SEMS in five obstructions, and fully covered SEMSs in five obstructions. Three stents occluded (two ingrowths and one mucosal hyperplasia), and one symptomatic distal stent migration occurred after more than 30 days from placement.
CONCLUSIONS: A short-type single-balloon enteroscope was useful for the placement of various SEMS in this patient population with satisfactory outcomes.
