Altered anatomy: enteroscopy and ERCP procedure.

Area of Science:

• Gastroenterology
• Surgical Innovation
• Endoscopic Procedures

Background:

• Roux-en-Y entero-enteric anastomosis is a common surgical technique.
• This surgical configuration limits conventional endoscopic access to the afferent limb and biliopancreatic system.
• Accessing these excluded segments for diagnostic and therapeutic interventions remains a clinical challenge.

Purpose of the Study:

• To review current literature on device-assisted enteroscopy (DAE) for endoscopic retrograde cholangiopancreatography (ERCP) in patients with Roux-en-Y anastomosis.
• To discuss the clinical utility, technical aspects, and challenges associated with DAE-ERCP in this patient population.

Main Methods:

• Comprehensive literature search of studies reporting DAE-ERCP in Roux-en-Y patients.
• Analysis of data regarding success rates, technical difficulties, and clinical outcomes.
• Review of different DAE platforms including Double-balloon, short Double-balloon, Single-balloon, and Spiral enteroscopy.

Main Results:

• DAE enables successful ERCP in patients with Roux-en-Y anastomosis, overcoming previous access limitations.
• Various DAE methods demonstrate comparable success rates for ERCP in this cohort.
• The procedure, while effective, presents significant technical challenges.

Conclusions:

• DAE significantly improves the efficacy of ERCP in patients who have undergone Roux-en-Y anastomosis.
• Despite advancements, DAE-ERCP in Roux-en-Y anatomy is a complex procedure requiring further refinement.
• Continued research and technical innovation are needed to optimize DAE-ERCP outcomes.
