Co-administration of L. casei is effective for the treatment of aspirin-associated small bowel injury.

AIP patients with IgG4 seropositivity and jaundice are at a higher risk of relapse and they could therefore be candidates for over 3 years of maintenance CST. AIP patients with IgG4 seronegativity have a high likelihood of SR.

Background and Aims: Chronic intestinal pseudo-obstruction (CIPO) is an intractable disease in which clinical symptoms of intestinal obstruction appear without mechanical cause. No clear diagnostic criteria have been established; therefore, we proposed diagnostic criteria to facilitate the diagnosis of this rare disease and aim to evaluate their usefulness and validity. Materials andMethods: A questionnaire was sent to 378 institutions belonging to the Japanese Society of Gastroenterology between December 2009 and February 2010. We summarized the returned data and performed a statistical analysis. Results: A total of 160 cases were included, and 141 cases (88.1%) fulfilled the criterion of disease duration of >6 months, 157 cases (98.1%) the criterion of the clinical symptoms of abdominal pain and/or bloating and 154 cases (96.2%) fulfilled the criterion of imaging findings. Eventually, 138 cases (86.3%) fulfilled all criteria. Conclusions: The proposed diagnostic criteria were useful, with a high sensitivity of 86.3% for Japanese patients. Improved recognition of CIPO and practical use of the criteria are desired. The criteria should be appropriately modified by additional researchers to make them more practical and internationally applicable.

The varix formation is an independent predictor of the development of ACF. A pooled analysis indicated that the disease process might be irreversible in AIP patients with large cystic lesions exceeding 55 mm in diameter and those patients tended to show a refractory course even if CST were conducted.

Our results indicated that bleeding pattern and clinical characteristics could contribute to predicting the origin of OGIB.
