SI: stent insertion; secretion score: n—normal (clear, serous); a—abnormal secretion (opaque, mucous) associated with ET lumen; 1—mucous/pus adhesion to perforated mucosa located anterior of the ET opening at the former HA injection site; 2—small bleeding after first stent insertion approach (stent was pulled out of the ET, change of stent side).
