Upper gastrointestinal endoscopy in the surgically altered patient

Area of Science:

• Gastroenterology
• Surgical Anatomy

Background:

• Improved management of upper gastrointestinal malignancies and increased bariatric surgeries lead to more patients with altered anatomy.
• Post-surgical complications include bleeding, leaks, fistulas, strictures, and stones, often requiring endoscopic intervention.
• Standard endoscopic procedures may be challenging in patients with complex gastrointestinal reconstructions.

Purpose of the Study:

• To outline the challenges and essential considerations for endoscopists managing patients with altered upper gastrointestinal anatomy.
• To emphasize the importance of understanding anatomical changes for successful endoscopic diagnosis and treatment.
• To guide endoscopists in preparing for and executing procedures in this patient population.

Main Methods:

• Review of common endoscopic interventions in patients with post-surgical upper gastrointestinal alterations.
• Discussion of diagnostic and therapeutic approaches for conditions like marginal ulcers and anastomotic strictures.
• Highlighting the potential need for advanced techniques like balloon-assisted enteroscopy for complex cases (e.g., Roux-en-Y gastric bypass).

Main Results:

• Standard endoscopic instruments can manage common conditions such as marginal ulcers and proximal anastomotic strictures.
• Complex reconstructions may necessitate specialized equipment and modified procedures, such as balloon-assisted enteroscopy for endoscopic retrograde cholangiopancreatography.
• Successful outcomes depend on a clear navigational plan and appropriate preparation.

Conclusions:

• Endoscopic management of patients with altered upper gastrointestinal anatomy requires a thorough understanding of the altered anatomy.
• Careful planning, appropriate equipment, and skilled execution are vital for successful endoscopic interventions.
• Specialized techniques and tools may be necessary for complex cases following bariatric surgery or other gastrointestinal reconstructions.
