title: Endoscopic and anesthetic feasibility of EUS and ERCP combined in a single session versus two different sessions.
abstract: OBJECTIVE
  To discuss the feasibility of single session endoscopic ultrasonography (EUS) to discuss and endoscopic retrograde cholangiopancreatography (ERCP) execution.
  
  
  METHODS
  Retrospective endoscopic and anesthetic outcome comparison of performing both EUS and ERCP in a single endoscopic session (Group I) versus performing each procedure in two different sessions (Group II) was made. The following variables were evaluated: epidemiological variables, American Society of Anesthesiologists Physical Status Classification (ASA) level, procedural time, propofol dose, anesthetic complications, endoscopic complications and diagnostic yield, and therapeutic procedures on both groups. T-student, Chi-Square and Fisher test were used for comparison.
  
  
  RESULTS
  We included 39 patients in Group I (mean age: 69.85 ± 9.25; 27 men) and 46 in Group II (mean age: 67.46 ± 12.57; 25 men). Procedural time did not differ significantly between both groups (Group Ivs Group II: 93 ± 32.78 vs 98.98 ± 38.17; P >0.05) but the dose of propofol differed (Group I vs Group II: 322.28 ± 250.54 mg vs 516.96 ± 289.06 mg; P = 0.001). Three patients had normal findings on both explorations. Three anesthetic complications [O(2) desaturation (2), broncoaspiration (1)] and 9 endoscopic complications [pancreatitis (6), bleeding (1), perforation (1), cholangitis (1)] occurred without significant differences between both groups (P > 0.05). We did not find any significant difference regarding age, sex, ASA scale level, diagnostic yield or therapeutic maneuvers between both groups.
  
  
  CONCLUSIONS
  The performance of EUS and ERCP in a single session offers a similar diagnostic and therapeutic yield, does not entail a higher complication risk and requires a significantly smaller dose of propofol for sedation compared with performing each exploration in a different session.
