TI  - Endoscopic Sphincterotomy before Fully Covered Metal Stent Placement Is Not 
      Required for Distal Malignant Biliary Stricture due to a Pancreatic Head Tumor.

AB  - BACKGROUND/AIMS: Endoscopic sphincterotomy (EST) is often performed before fully 
      covered self-expandable metal stent (FCSEMS) placement in order to prevent 
      pancreatitis. However, it is not clear whether EST prevents pancreatitis or 
      affects other adverse events (AEs). This study is conducted to evaluate the 
      necessity of EST before FCSEMS placement for distal malignant biliary strictures 
      due to a pancreatic head tumor. METHODS: This study included 68 patients who 
      underwent FCSEMS placement for distal malignant biliary stricture due to a 
      pancreatic head tumor. Treatment outcomes and AEs were retrospectively compared 
      between 32 patients with EST before FCSEMS placement (EST group) and 36 patients 
      without EST (non-EST group). RESULTS: The success rates of drainage for the EST 
      and non-EST groups were 100% and 97.2%, respectively (P = 0.95). The incidence of 
      pancreatitis in the EST and non-EST groups was 3.1% and 0%, respectively (P = 
      0.95). The incidence of hyperamylasemia in the EST and non-EST groups was 12.5% 
      and 13.9%, respectively (P = 0.85). The incidence of all AEs in the EST and 
      non-EST groups was 15.6% (pancreatitis: 1, cholecystitis: 2, and stent migration: 
      2) and 13.9% (cholecystitis: 3, stent migration: 2), respectively (P = 0.89). 
      CONCLUSIONS: EST before FCSEMS placement for distal malignant biliary stricture 
      due to a pancreatic head tumor does not affect the successful drainage and 
      incidence of adverse events. The necessity of EST to prevent pancreatitis before 
      FCSEMS placement was deemed low.
