Effect of limited endoscopic sphincterotomy before self-expandable metal stent insertion for malignant biliary obstruction

[...]it is advantageous in facilitating the more complex stenting procedures. [...]limited ES can be a safe, feasible, and effective therapeutic strategy in the placement of self-expandable metal stent. The diagnosis of malignant biliary obstruction and assessment of patient eligibility for the study was established by a combination of clinical findings, laboratory investigations, imaging and pathological results. In our study, stent migration occurred in only 1 patient (0.4%) and limited ES did not seem to be a significant factor associated with migration, regardless of the stent type Conclusion: Limited ES is feasible and safe, and effectively facilitates the placement of SEMS, without any significant risk of PEP or severe bleeding.
