Clinical Trial Summary

Compared with two-person in single-balloon enteroscopy, one-person single-balloon enteroscopy has the advantages of better observation and treatment of lesions, shorter examination time, saving resources in the endoscopy room, and reducing the postoperative discomfort of the examined person, etc. However, there is no comparative study of one-person and two-person in single-balloon enteroscopy.

Description:

The incidence rate of chronic small bowel disease in China is 6.14%. Due to the deep location, large length, tortuous shape and large free degree, the diagnosis and treatment of small bowel disease has always been a major challenge in the clinical work of gastroenterology. Although capsule endoscopy can realize the observation of the whole small intestinal mucosa, it cannot effectively observe in real time the suspicious lesions, much less treatment, and its many difficulties still need to be resolved. Enteroscopy allows for real-time, direct visualization of the small intestine and provide effective treatment, which is an important tool for the diagnosis and treatment of small intestinal diseases. The depth of small bowel insertion and whole small bowel examination rate are important indicators for evaluating enteroscopy. However, due to objective factors, such as lesion location and luminal stenosis, the depth of insertion is a better indicator of the quality of enteroscopy, which is more in line with clinical needs.Currently,the single-balloon enteroscopy, which is now more common in clinical practice, have been designed and optimized for relative ease of operation and a shorter learning curve.Compared with two-person in single-balloon enteroscopy, one-person single-balloon enteroscopy has the advantages of better observation and treatment of lesions, shorter examination time, saving resources in the endoscopy room, and reducing the postoperative discomfort of the examined person, etc. However, there is no comparative study of one-person and two-person in single-balloon enteroscopy.Therefore, we propose to conduct a multicenter, noninferiority, randomized controlled study to explore the effect of single and double operation on single balloon small bowel insertion depth, total small bowel examination rate, and lesion detection rate.
