Abstract

AIM: 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 [O2 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.

CONCLUSION: 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.
