[Usefulness and safety of observing anorectal lesions by colon capsule endoscopy].

We investigated the findings of rectoanal lesions in 190 patients who underwent colon capsule endoscopy (CCE) at our hospital. Internal hemorrhoids were observed in 70 (36.8%) patients and rectal polyps in 19 (10%) patients.

Follow-up outcomes in patients with negative initial colon capsule endoscopy findings.

Background: Colon capsule endoscopy (CCE), which became clinically applicable in 2006, is a simple and noninvasive procedure to evaluate colonic diseases; the accuracy of second-generation CCE, introduced in 2009, has dramatically improved. Currently, CCE is used as an alternative method for colorectal cancer screening, as well as for evaluating the mucosal lesions of inflammatory bowel disease, in cases where performing colonoscopy (CS) is difficult. However, the outcomes of CCE are uncertain.

Continuous warfarin administration versus heparin bridging therapy in post colorectal polypectomy haemorrhage: a study protocol for a multicentre randomised controlled trial (WHICH study).

Background: Endoscopic removal of colorectal adenoma is considered an effective treatment for reducing the mortality rates associated with colorectal cancer. Warfarin, a type of anticoagulant, is widely used for the treatment and prevention of thromboembolism; however, bleeding may increase with its administration after polypectomy. In recent times, a high incidence of bleeding after endoscopic polypectomy has been reported in patients receiving heparin bridge therapy.

[A case of melena and perforation during chemotherapy for peripheral T-cell lymphoma, not otherwise specified of the small intestine].

A 71-year-old male presented with gastrointestinal bleeding. Double-balloon endoscopy revealed diffuse thickening of the wall and a shallow ulcer measuring approximately 10cm in the mid jejunum. Biopsy revealed diffuse proliferation of large lymphoid cells that were immunohistochemically positive for CD3, CD5, and bcl-2 but negative for CK, CD10, CD20, and bcl-6.

Effects in the control of edema of the papilla of Vater by epinephrine saline irrigation after endoscopic retrograde cholangiopancreatography in an endoscopy center in Japan, 2003 to 2007: exploratory retrospective analysis to evaluate the characteristics of eligible patients with a focus on serum amylase levels.

Objective: To evaluate the effects of localized irrigation with epinephrine saline after endoscopic retrograde cholangiopancreatography (ERCP).

Patients And Methods: One hundred and fourteen patients who underwent ERCP in our institute were treated with or without irrigation using epinephrine diluted in saline after ERCP to prevent post-ERCP pancreatitis. The serum amylase levels, white blood cell counts, and urine amylase levels were measured at 24 and 48 hours after ERCP.

Nodular gastritis in Japanese young adults: endoscopic and histological observations.

Background: Endoscopic findings of nodular gastritis (NG) are characterized by the presence of Helicobacter pylori infection and follicular gastritis. A possible association with diffuse-type gastric cancer has recently been suggested from observations in Japanese. Our aim was to analyze antral nodularity and histological scores in young adults.

Evidence that loss of sonic hedgehog is an indicator of Helicobater pylori-induced atrophic gastritis progressing to gastric cancer.

Background: The absence of sonic hedgehog (Shh) correlates with the development of intestinal metaplasia (IM) suggesting the possibility of an association between Shh expression and neoplastic transformation.

Aim: To examine Shh expression in the noncancerous mucosa of patients with gastric cancer and compare it to Shh expression in Helicobater pylori-infected and uninfected controls. We also assessed the relationship between the type of IM and Shh expression.
