Does anesthesiologist-directed sedation for ERCP improve deep cannulation and complication rates?

Area of Science:

• Gastroenterology
• Anesthesiology
• Medical Procedures

Background:

• Sedation for endoscopic retrograde cholangiopancreatography (ERCP) can be managed by gastroenterologists or anesthesiologists.
• Limited data exists comparing deep cannulation success and complication rates between these two sedation approaches.
• Anesthesiologist-directed sedation (ADS) theoretically may improve deep cannulation due to consistent sedation levels and dedicated monitoring.

Purpose of the Study:

• To compare the success rates of deep cannulation during ERCP.
• To evaluate procedural complication rates between gastroenterologist-directed sedation (GDS) and ADS.
• To determine if sedation provider impacts ERCP outcomes.

Main Methods:

• A retrospective review of ERCPs performed by senior endoscopists over two years.
• Sedation was managed by GDS (narcotic and benzodiazepine) in year one and ADS in year two.
• Patients with prior papillary interventions were excluded; deep cannulation success and complications were recorded.

Main Results:

• A total of 367 patients were analyzed: 178 (48.5%) under GDS and 189 (51.5%) under ADS.
• No significant differences were observed in demographics between the GDS and ADS groups.
• Overall cannulation success rates were similar (94.4% GDS vs. 95.2% ADS, P=0.36), with comparable complication profiles.

Conclusions:

• Deep ductal cannulation rates during ERCP are similar regardless of whether sedation is provided by gastroenterologists or anesthesiologists.
• The choice of sedation provider (GDS vs. ADS) does not appear to significantly impact ERCP deep cannulation success.
• Complication rates were also comparable between the GDS and ADS groups.
