Clinical impact of disposable elevator-cap duodenoscopes on post-ERCP cholangitis: a prospective cohort study.

New evidenceERCPendoscopy quality
Clinical takeawayDEC duodenoscopes do not reduce post-ERCP cholangitis in routine practice. Although surveillance cultures showed superior sterilization, this study does not support institutional adoption of DEC equipment specifically to prevent post-ERCP cholangitis.
What it foundDisposable elevator-cap duodenoscopes achieved zero microbial contamination on surveillance cultures versus contamination detected in conventional duodenoscopes, yet MDR pathogen-associated post-ERCP cholangitis occurred identically in both groups: 2.5% (8/318 DEC vs 18/721 conventional), with no significant difference after propensity score matching.
ContextChallenges the microbiologic rationale for DEC duodenoscopes. The technology achieved superior cleanliness on surveillance culture, yet clinical outcomes for post-ERCP cholangitis were identical to conventional equipment, suggesting the microbiologic benefit does not translate to clinically meaningful infection prevention.

Our full summary of this standard

For right upper quadrant pain, characterize the pattern (acute vs chronic, post-meal vs unrelated, with vs without fever/jaundice) and triage acute red-flag presentations (Murphy sign, Charcot's triad, painless jaundice with weight loss, pregnancy with LFT/coagulation derangement) to the ED. Obtain labs (CBC, CMP with LFTs, lipase, urinalysis, pregnancy test in reproductive-age women) and RUQ ultrasound as first imaging, then direct further workup by ultrasound findings, cholecystectomy for acute cholecystitis, MRCP for suspected choledocholithiasis based on risk stratification (e.g., high-risk criteria including CBD dilation >6 mm, bilirubin >4 mg/dL, or gallstone pancreatitis), CCK-HIDA/GBEF for acalculous functional gallbladder disorder, and cross-sectional imaging for liver masses or other pathology.
