Endoscopy of the partitioned stomach

Area of Science:

• Gastroenterology
• Surgical Procedures
• Diagnostic Imaging

Background:

• Upper gastrointestinal (GI) symptoms are common post-gastric bypass and gastroplasty.
• Fiberoptic endoscopy is crucial for evaluating these symptoms.
• Altered anatomy presents unique diagnostic challenges.

Purpose of the Study:

• To assess the utility of fiberoptic endoscopy in patients with upper GI symptoms after gastric partitioning.
• To identify common endoscopic findings and complications.
• To evaluate the accuracy of endoscopy compared to contrast studies.

Main Methods:

• Retrospective review of 182 patients undergoing gastric partitioning over 3 years.
• Endoscopic evaluation of 22 patients (12%) with upper GI symptoms.
• Analysis of findings including gastritis, obstruction, and channel stenosis.
• Comparison of endoscopic findings with upper GI contrast studies.

Main Results:

• Gastritis was observed in 4/5 patients with abdominal pain.
• One case of proximal gastric outlet obstruction due to a 'cherry pit' was noted.
• Endoscopic dilation was performed for channel stenosis in 4/8 patients.
• Endoscopy provided more accurate channel diameter assessment than contrast studies.

Conclusions:

• Fiberoptic endoscopy is essential for diagnosing upper GI issues post-gastric partitioning.
• Familiarity with altered anatomy and potential lesions is critical for endoscopists.
• Endoscopy effectively identifies and manages complications like stenosis and gastritis.
