Risk factors for short-term re-bleeding in patients with colonic diverticular bleeding: a multicenter retrospective study.

Background And Aim: Few studies have evaluated risk factors for short-term re-bleeding in patients with colonic diverticular bleeding (CDB). We aimed to reveal risk factors for re-bleeding within a month in patients with CDB.

Methods: We retrospectively analyzed clinical course of patients with CDB diagnosed at 10 institutions between 2015 and 2019.

Self-study of the non-extension sign in an e-learning program improves diagnostic accuracy of invasion depth of early gastric cancer.

 We developed an e-learning program for endoscopic diagnosis of invasion depth of early gastric cancer (EGC) using a simple diagnostic criterion called non-extension sign, and the contribution of self-study quizzes to improvement of diagnostic accuracy was evaluated.  We conducted a prospective randomized controlled study that recruited endoscopists throughout Japan. After completing a pretest, the participants watched video lectures and undertook post-test 1.

Dabigatran-induced esophagitis: The prevalence and endoscopic characteristics.

Background And Aim: There have been some descriptions of dabigatran-induced esophagitis in the literature. The aim of this study was to examine the prevalence and endoscopic characteristics of the disease.

Methods: We reviewed the endoscopic database and medical records of 91 patients with dabigatran internal use who underwent upper gastrointestinal endoscopy.

Lipoma of the small intestine treated with endoscopic resection.

We report a case of lipoma of the small intestine that was treated by endoscopic resection. A 79-year-old man who complained of tarry stool was diagnosed as having jejunal tumor at a neighboring clinic. Computed tomography (CT) and enteroscopy demonstrated an ulcerating jejunal mass.

The effect of granulocyte and monocyte adsorptive apheresis on serum cytokine levels in patients with ulcerative colitis.

Granulocyte and monocyte adsorptive apheresis (GMA) with an Adacolumn has been reported to be effective as induction therapy in ulcerative colitis (UC). However, the effects of GMA on serial changes in cytokine levels have not been well characterized. We therefore, investigated cytokine levels in UC patients before and after treatment with GMA.

Peripheral Blood CD64 Levels Decrease in Crohn's Disease following Granulocyte and Monocyte Adsorptive Apheresis.

Granulocyte and monocyte adsorptive apheresis (GMA) is reportedly useful as induction therapy for Crohn's disease (CD). However, the effects of GMA on CD64 have not been well characterized. We report here our assessment of CD64 expression on neutrophils before and after treatment with GMA in two patients with CD.
