Endoscopy in Patients With Surgically Altered Anatomy

Area of Science:

• Gastroenterology
• Surgical Anatomy
• Endoscopic Procedures

Background:

• Endoscopic procedures require comprehensive gastrointestinal anatomy knowledge.
• Surgically altered anatomy is increasingly common due to bariatric and other GI surgeries.
• Gastroenterologists must adapt to these anatomical changes for diagnosis and therapy.

Purpose of the Study:

• To review common surgically altered upper gastrointestinal anatomy.
• To detail surgical approaches affecting the esophagus, stomach, and small bowel.
• To provide an endoscopic roadmap and guidance for procedures in altered anatomy.

Main Methods:

• Literature review of surgical approaches and their impact on GI anatomy.
• Description of anatomical alterations in the esophagus, stomach, and small bowel.
• Guidance on endoscopic procedures, including endoscopic ultrasound and ERCP, in post-surgical patients.

Main Results:

• Common surgical alterations to the esophagus, stomach, and small bowel are described.
• Specific surgical techniques and their anatomical consequences are detailed.
• The review provides practical guidance for endoscopic interventions in patients with altered anatomy.

Conclusions:

• Familiarity with post-surgical gastrointestinal anatomy is crucial for gastroenterologists.
• Understanding anatomical implications enhances safety and efficacy of endoscopic modalities.
• Evolving endoscopic techniques promise improved outcomes for patients with surgically altered anatomy.
