Efficacy of the Pediatric Colonoscope Used as a Push Enteroscope

چکیده
Numerous advances have recently been made in endoscopy for both diagnosis and treatment of gastrointestinal diseases. However, these advances have taken little account of the small bowel, as access by endoscopy is often difficult. With the advent of push endoscopy in 1971, the proximal jejunum could be examined to about 50 cm from the ligament of Treitz. The subsequent introduction of videoendoscopy combined with an overtube enabled us to examine the whole jejunum. The most recent discoveries—capsule endoscopy and double-balloon enteroscopy—have improved our ability to examine the small intestine. Capsule endoscopy has provided us with a new challenge, namely, how to diagnose and treat the lesions found. Hospitals with a small bowel unit in which doubleballoon enteroscopy and push endoscopy are available can provide an effective solution in a large percentage of cases. In hospitals where these techniques are not available, lesions identified in the jejunum must be resolved using non-balloon enteroscopy. Colonoscopy is a well-known alternative, although its rigidity and caliber prevent it from advancing smoothly through the jejunum. An intermediate solution could be found in the pediatric colonoscope, which is smaller in cross-section and more flexible and has a working channel that enables therapy to be administered. In this chapter, we describe the different diagnostic therapeutic approaches to lesions of the small bowel. We also examine the application of endoscopy, including the possibilities offered by the pediatric colonoscope in the diagnosis and treatment of lesions found using capsule endoscopy.

Safety and efficacy of small bowel polypectomy using a balloon-assisted enteroscope in pediatric patients with Peutz-Jeghers syndrome.
INTRODUCTION AND AIMS Peutz-Jeghers syndrome is an autosomal dominant inherited pathology characterized by gastrointestinal hamartomatous polyps, predominantly in the small bowel, and pigmented mucocutaneous lesions. Guidelines suggest polypectomy with a balloon-assisted enteroscope when polyps are larger than 10mm. Complications in adults can be as high as 6.8%, but there is little information...
متن کاملEfficacy of pediatric colonoscopy used as push enteroscopy in the management of capsule endoscopy findings.
BACKGROUND recent advances in endoscopy have enabled us to explore the small intestine more efficiently, both with capsule endoscopy and double-balloon enteroscopy. However, these methods are not available in all hospitals. Therefore, when capsule endoscopy reveals proximal jejunal lesions, a possible alternative for treatment could involve push enteroscopy combined with colonoscopy. Lesions ca...
متن کاملUse of a Through-the-Scope Balloon System for Deep Enteroscopy.
SG The through-the-scope balloon system consists of a balloon catheter that is placed through the end of a colonoscope and allows the endoscopist to advance deep into the small intestine via the stomach or the colon. The balloon is pushed out in front of the colonoscope, anchored in the small bowel, and inflated. Through a series of balloon inflations and deflations, the colonoscope advances al...
متن کاملSuccessful ERCP in a Roux-en-Y gastric bypass patient, performed via a small remnant of gastrogastric communication.
tography (ERCP) can be challenging in patients after Roux-en-Y gastric bypass surgery. We present a case of such a patient with choledocholithiasis who underwent successful ERCP though a remnant of gastrogastric communication. A 57-year-old female after successful Roux-en-Y-gastric bypass presented with symptomatic choledocholithiasis. ERCP with a pediatric colonoscope was unsuccessful because ...
متن کاملOverview of deep small bowel enteroscopy
Alternative endoscopic approaches have been developed to overcome these limitations. Deep small bowel enteroscopy permits visualization and interventional therapy throughout the small bowel by using insertion techniques that pleat the small bowel onto an overtube. The techniques used for deep small bowel enteroscopy limit stretching of the small bowel (as occurs with push enteroscopy), permit b...
