Comparison of detectability of small-bowel lesions between capsule endoscopy and double-balloon endoscopy for patients with suspected small-bowel disease

Autor: Yoshito Takemura, Kazuaki Chayama, Takayoshi Shishido, Shiro Oka, Akira Fukumoto, Shinji Tanaka

Publikováno v: Gastrointestinal Endoscopy. 69:857-865

Background There are many reports of the usefulness of capsule endoscopy (CE) or double-balloon endoscopy (DBE) for the detection of small-bowel disease. However, there are few reports that compared CE and DBE. Objective To determine whether CE or DB

Publikováno v: Medical image analysis. 17(1)

An early detection of colorectal cancer through colorectal endoscopy is important and widely used in hospitals as a standard medical procedure. During colonoscopy, the lesions of colorectal tumors on the colon surface are visually inspected by a Narr

Background Narrow-band imaging (NBI) classification of colorectal lesions is clinically useful in determining treatment options for colorectal tumors. There is a learning curve, however. Accurate NBI-based diagnosis requires training and experience.

Publikováno v: Journal of gastroenterology. 46(12)

Background Various surface mucosal pit patterns, as recognized by endoscopists, correlate with the histologic features of colorectal cancers. We investigated whether magnified endoscopy images of these pit patterns could be analyzed quantitatively an

Publikováno v: Abdominal imaging. 37(2)

To determine whether contrast-enhanced ultrasonography (CEUS) can be used to discriminate between colon cancer and acute inflammation, and between mucinous and non-mucinous carcinoma. CEUS (with perflubutane microbubbles) was performed in two study g

Publikováno v: World journal of gastroenterology. 18(7)

To assess the diagnostic success and outcome among patients with obscure gastrointestinal bleeding who underwent total enteroscopy with double-balloon endoscopy.Total enteroscopy was attempted in 156 patients between August 2003 and June 2008 at Hiro

ACCV (2)

In this paper we propose a recognition system for classifying NBI images of colorectal tumors into three types (A, B, and C3) of structures of microvessels on the colorectal surface. These types have a strong correlation with histologic diagnosis: hy
