Summary
Push enteroscopy of the small bowel (PES) is effective for diagnosing gastrointestinal bleeding from unknown sources, potentially avoiding surgery. However, PES offers limited diagnostic value for other conditions like chronic diarrhea or lymphoma.
Area of Science:
- Gastroenterology
- Endoscopic Procedures
- Diagnostic Medicine
Background:
- Uncertain gastrointestinal bleeding, chronic diarrhea, and small intestine lymphoma often require extensive investigation.
- Push enteroscopy of the small bowel (PES) is an endoscopic technique used for visualizing the small intestine.
Purpose of the Study:
- To evaluate the diagnostic contribution and clinical significance of PES.
- To assess the outcomes of PES in patients with suspected intestinal bleeding, chronic diarrhea, or lymphoma.
Main Methods:
- A prospective study of 56 consecutive patients undergoing PES.
- Indications included obscure gastrointestinal bleeding (79%), chronic diarrhea (16%), and lymphoma/tumor search (5%).
- Video PES was performed under sedation, allowing for intervention.
Main Results:
- Lesions, primarily angiodysplasias, were found in 27% of patients with obscure bleeding.
- Half of these patients with bleeding were successfully treated endoscopically, avoiding surgery.
- PES reached only 50% of the small intestine length; no abnormalities were found in patients with diarrhea or lymphoma.
Conclusions:
- PES should be the initial procedure for obscure gastrointestinal bleeding, potentially obviating surgery.
- PES has limited diagnostic value for chronic diarrhea or suspected lymphoma of the small intestine.
