A Novel Method to Localize Patency Capsule by Ileocolonoscopy Facilitates Endoscopic Assessment of the Small and Large Intestine in Patients with Crohn's Disease.

Introduction: Patients with Crohn's disease (CD) require an assessment of small bowel lesions, while difficulties exist in performing small intestinal examinations, especially in small-sized medical offices. Small bowel capsule endoscopy (SBCE) is handy and can be performed in most clinical settings. The only drawback of SBCE is a requirement of patency testing prior to the exam because it sometimes requires CT scanning to localize the ingested patency capsule (PC), which may be a substantial burden for the patient.

Severe Disease Activity May Predispose Patients to Post-colectomy Duodenitis Associated with Ulcerative Colitis.

Objective Diffuse mucosal inflammation in the duodenum, distinct from peptic ulcer disease, has been repeatedly reported in patients with ulcerative colitis (UC). The pathogenesis of this complication remains uncertain; however, colectomy for medically refractory UC appears to trigger duodenitis. Cases in which colectomy was performed for UC were analyzed to characterize UC-related duodenitis after colectomy.

Safety Prediction of Infants Born to Mothers with Crohn's Disease Treated with Biological Agents in the Late Gestation Period.

Objectives: Knowledge gaps exist in the use of biologics for pregnant patients with Crohn's disease (CD), especially the usage of ustekinumab (UST) and infliximab (IFX) infusion during the late gestation period. In this case series, we investigated perinatal and neonatal outcomes and pharmacokinetics of these biologics in pregnant CD patients.

Methods: Pregnant CD patients under treatment with IFX or UST during January 2017 to December 2019 were monitored.

A case of refractory chronic pouchitis successfully treated with tofacitinib.

We describe a case of refractory pouchitis successfully treated with tofacitinib. The patient was a 20-year-old woman diagnosed with ulcerative colitis at the age of 14 years. She underwent surgery at the age of 18 years for chronic active inflammation, despite an optimal medication regimen.

[Three cases of severe and fulminating ulcerative colitis with megacolon treated with continuous intravenous infusion of cyclosporine].

Dilatation of the colon in severe and fulminating ulcerative colitis is a sign of toxic megacolon and emergency surgery is usually the favored treatment option. Here we describe our experience with three cases of ulcerative colitis with megacolon in which surgery was avoided by treating the patients with a continuous intravenous infusion of cyclosporine, with full cooperation of the surgeons. We recommend that continuous intravenous infusion of cyclosporine be considered as an effective option for the conservative management of severe, fulminating ulcerative colitis with megacolon.
