Patients with borderline resectable pancreatic head cancer (BRPHC) have been treated with neoadjuvant chemoradiation therapy (NACRT) using metallic stents. The aim of the present study was to evaluate the efficacy and complications of covered self-expanding metallic stents (CSEMS) during the NACRT and surgical period. ⋯ CSEMS should be considered to relieve symptomatic biliary obstruction in patients with BRPHC receiving NACRT in view of the high attainability rate of safe R0 surgery compared to that with PS deployment.

Multicenter Study
High single-session success rate of endoscopic bilateral stent-in-stent placement with modified large cell Niti-S stents for malignant hilar biliary obstruction.
Endoscopic bilateral self-expandable metallic stent (SEMS) placement in a stent-in-stent method for malignant hilar biliary obstruction is technically challenging. Technical difficulties in the initial placement and reinterventions for stent occlusion are disadvantages inherent to this stent-in-stent method. We previously reported the feasibility of Niti-S large cell D-type biliary stents (LCD). This multicenter prospective consecutive study evaluated the efficacy of bilateral SEMS placement using modified LCD with large and uniform cells, a slimmer delivery system and high radial force. ⋯ Modified LCD achieved a high technical success rate both in the initial stent-in-stent placement and in bilateral reinterventions in patients with malignant hilar biliary obstruction.

The aim of the present study was to clarify the efficacy of peroral endoscopic myotomy (POEM) for esophageal achalasia. ⋯ POEM could be a curative standard treatment of choice for esophageal achalasia.
