Diffuse gastrointestinal tract and colonic involvement are uncommon. The endoscopic appearance may vary from normal to mucosal nodularity and ulceration. Gastrointestinal obstruction is unusual and is associated with predominantly muscular disease. We present five unusual cases of EG associated with gastric outlet and duodenal obstruction. Two cases presented with acute pancreatitis and one had a history of pancreatitis. Four cases responded well to medical therapy and one had recurrent gastric outlet obstruction that required surgery. Four out of the five cases had endoscopic and histological evidence of esophagitis and two had colitis. Two patients had ascites. These cases reaffirm that EG is a disorder with protean manifestations and may involve the entire gastrointestinal tract. Gastric outlet and/or small bowel obstruction is an important though uncommon presentation of EG. It may also present as esophagitis, gastritis with polypoid lesions, ulcers or erosions, colitis and pancreatitis and may mimic malignancy.展开更多

The disease is divided into three subtypes (mucosal, muscular and serosal) according to klein’s classification, and its manifestations are protean, depending on the involved intestinal segments and layers. Hence, accurate diagnosis of EGE poses a significant challenge to clinicians, with evidence of the following three criteria required: Suspicious clinical symptoms, histologic evidence of eosinophilic infiltration in the bowel and exclusion of other pathologies with similar findings. In this review, we designed and applied an algorithm to clarify the steps to follow for diagnosis of EGE in clinical practice. The management of EGE represents another area of debate. Prednisone remains the mainstay of treatment; however the disease is recognized as a chronic disorder and one that most frequently follows a relapsing course that requires maintenance therapy. Since prolonged steroid treatment carries of risk of serious adverse effects, other options with better safety profiles have been proposed; these include budesonide, dietary restrictions and steroid-sparing agents, such as leukotriene inhibitors, azathioprine, anti-histamines and mast-cell stabilizers. Single cases or small case series have been reported in the literature for all of these options, and we provide in this review a summary of these various therapeutic modalities, placing them within the context of our novel algorithm for EGE management according to disease severity upon presentation.展开更多

Published studies have reported incidence of PI-IBS to range between 5% and 32%. The mechanisms underlying the development of PI-IBS are not fully understood, but are believed to include persistent sub-clinical inflammation, changes in intestinal permeability and alteration of gut flora. Individual studies have suggested that risk factors for PI-IBS include patients' demographics, psychological disorders and the severity of enteric illness. However, PI-IBS remains a diagnosis of exclusion with no specific disease markers and, to date, no definitive therapy exists. The prognosis of PIIBS appears favorable with spontaneous and gradual resolution of symptoms in most patients.展开更多
