Background:
Double balloon endoscopy (DBE) is a new diagnostic and therapeutic tool for the management of patients with small-bowel disease.
Objective:
To evaluate the feasibility, clinical usefulness, and safety of DBE in Korean patients with suspected or known small-bowel disease.
Design:
Retrospective, multicenter study from April 2004 to March 2006.
Setting:
University hospitals.
Patients:
Two hundred twenty-five consecutive patients.
Interventions:
Subjects underwent 311 procedures with DBE via the oral and/or anal routes.
Main Outcome Measurements:
The indications, diagnostic yield, therapeutic use, and complications.
Results:
Overall diagnostic yield was 75% (169/225). Diagnostic yields for obscure GI bleeding (OGIB) (n = 137), chronic abdominal pain (n = 32), radiologic/capule endoscopic abnormality (n = 25), polyposis (n = 9), and chronic diarrhea (n = 9) were 73.7% (101/137), 75.0% (24/32), 64% (16/25), 100% (9/9), and 0% (0/9), respectively. In patients with OGIB, ulcerating lesions (n = 54) were more common than vascular lesions (n = 20) or tumors (n = 27). Some lesions detected in DBE were treated effectively with electrocoagulation or argon plasma coagulation, polypectomy, and dilation. Entrapped capsules were removed easily with polypectomy snare in 3 patients with small-bowel stricture. Some patients with strictures had transient abdominal discomfort during and/or after the procedure. With the exception of 1 mucosal tear, there were no technical problems or serious complications.
Limitations:
Descriptive, retrospective study.
Conclusions:
DBE is safe and useful for diagnosis and treatment of a variety of small-bowel diseases. The most common indication of DBE was OGIB. Ulcerating small-bowel lesions are more common than vascular lesions in Korea.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...

Radionuclide Testing
Radionuclide testing is a sophisticated medical technique for assessing gastrointestinal motility. It focuses on gastric emptying and colonic transit time. Radioactive markers track the movement of food through the digestive system, providing insights into gastrointestinal disorders.
