BACKGROUND: Nonocclusive disease (NOD) is known to be a common cause of ischemic colitis, which is frequently underestimated. MATERIAL AND METHODS: A computer-assisted search of radiological reports at our institute over a period of 18 months, describing ischemic colitis of the ascending colon with an unimpaired perfusion of the superior mesenteric artery, was performed. RESULTS: A retrospective analysis of the clinical and radiological data of 14 patients was performed. In ten cases colonic ischemia was confirmed clinically or intraoperatively. Most of our patients needed intravenous catecholamines due to severe hypotension. However, no significant radiographic predictors could be identified. CONCLUSION: Awareness of NOD seems to be crucial. Especially in cases of acute abdominal pain associated with severe hypotension, renal insufficiency, or pancreatitis, one should include NOD as a differential diagnosis at an early stage.
INTRODUCTION: Screening studies of healthy volunteers have determined that coeliac disease affects 1% of the adult European population. Despite this, the majority of cases are unrecognised. Coeliac disease often presents in adults with non-specific gastrointestinal symptoms. This may suggest that unrecognised cases are being seen in colorectal clinics with vague gastrointestinal symptoms, iron deficiency anaemia or irritable bowel syndrome. In addition, cases of coeliac disease may also be presenting as an emergency admission with non-specific abdominal pain. OBJECTIVE: This review provides an update of the published data on case finding for coeliac disease, with the aim of improving the recognition of this disease in clinical practice.
OBJECTIVES: The endoscopic secretin test (ePFT) takes an hour to perform, limiting its practicality for routine use. We sought to determine which timed endoscopic collections best predict the peak bicarbonate concentration from full hour-long test. METHODS: A cross-sectional study was performed of all ePFTs performed at our institution from 2000 to 2004. We compared 7 theoretical shortened tests [4-single collections (15, 30, 45, or 60 minutes after secretin) and 3-dual collections (15/30, 30/45, 45/60 minutes after secretin)] to the full test and to each other using multivariate linear and Deming regression models. RESULTS: The bicarbonate results of 240 ePFTs were analyzed. The dual 30/45-minute collection was the optimal method based on the closest agreement with the full test (94%). Deming regression reveals the 30/45 estimate to be the best combination from an analytic perspective, owing to its lack of significant proportional bias and minimal constant bias (5.1 mEq/L) as compared to the reference test. Use of the 30/45 method with the adjusted cutpoint 75 mEq/L produces very good specificity (93%) for ruling in exocrine insufficiency. CONCLUSIONS: A dual timed aspiration at 30 and 45 minutes can be used to screen for pancreatic exocrine insufficiency in patients with abdominal pain, simplifying the use of the ePFT in clinical practice.
