Small-Bowel Diagnosis in Patients with Familial Adenomatous Polyposis: Comparison of Push Enteroscopy, Capsule Endoscopy, Ileoscopy, and Enteroclysis
2009
BACKGROUND: Conventional upper endoscopy (EGD), EGD with side-view endoscope and ileoscopy are established procedures for endoscopic evaluation of patients with familial adenomatous polyposis (FAP). However, we still have little data on the frequency and relevance of adenomas in those parts of the small bowel which are not accessible to EGD and ileoscopy. Adenomas distal to the duodenum are found more often in FAP patients with known duodenal adenomas. The question is, whether these patients can benefit from additional endoscopic and/or radiographic examinations. METHODS: Between July 2001 and August 2006 we performed comparative small bowel studies with push enteroscopy (PE), capsule endos…
Accuracy of magnetic resonance enterography in the preoperative assessment of patients with Crohn's disease of the small bowel
2016
Aim to assess the accuracy of magnetic resonance-enterography in predicting the extension, location and characteristics of the small bowel segments affected by Crohn's disease. Method This is a prospective study including a consecutive series of 38 patients with small bowel Crohn's disease who underwent surgery at a specialized colorectal unit of a tertiary hospital. Preoperative magnetic resonance enterography was performed in all patients, following a homogeneous protocol, within the three months prior to surgery. A thorough exploration of the small bowel was performed during the surgical procedure, using calibration spheres, according to the discretion of the surgeon. The accuracy of mag…
Small intestine bacterial overgrowth and irritable bowel syndrome-related symptoms: Experience with Rifaximin
2009
AIM: To estimate the prevalence of small intestinal bacterial overgrowth (SIBO) in our geographical area (Western Sicily, Italy) by means of an observational study, and to gather information on the use of locally active, non-absorbable antibiotics for treatment of SIBO. METHODS: Our survey included 115 patients fulfilling the Rome II criteria for diagnosis of irritable bowel syndrome (IBS); a total of 97 patients accepted to perform a breath test with lactulose (BTLact), and those who had a positive test, received Rifaximin (Normix®, Alfa Wassermann) 1200 mg/d for 7 d; 3 wk after the end of treatment, the BTLact was repeated. RESULTS: Based on the BTLact results, SIBO was present in about 5…
Capsule Endoscopy versus Push Enteroscopy in Patients with Occult Gastrointestinal Bleeding
2003
Background Wireless capsule endoscopy is a new method enabling non-invasive diagnostic endoscopy of the entire small intestine. In this study we prospectively examined the diagnostic precision of capsule endoscopy compared with push enteroscopy in patients with occult gastrointestinal bleeding. Methods Between July 2001 and October 2002 we examined 48 patients with suspected disorders of the small intestine using capsule endoscopy. 33 patients with obscure bleeding (19 men, 14 women, mean age 58 +/- 23 years) were prospectively examined using capsule endoscopy and push enteroscopy. Results On average, the patients had been suffering from chronic gastrointestinal bleeding for 30 +/- 36 (1-12…
CT enterography as a powerful tool for the evaluation of inflammatory activity in Crohn’s disease: relationship of CT findings with CDAI and acute-ph…
2014
Few studies have correlated computed tomography enterography (CTE) findings with Crohn’s disease (CD) clinical and biochemical activity. The aim of this study was to evaluate correlations between CTE findings with CD activity. The CTE datasets from 62 patients were retrospectively reviewed for different parameters: bowel wall thickening and hyperenhancement, mesenteric alterations, abdominal free fluid and complications related to the disease (fistulas, strictures, abscesses). Activity was assessed using the Crohn’s Disease Activity Index (CDAI) and some biochemical markers (C-reactive protein, erythrocyte sedimentation rate, alpha 2-globulins, fibrinogen, platelets, haemoglobin). Correlati…
Local anesthetic switching for intrathecal tachyphylaxis in cancer patients with pain.
2003
IMPLICATIONS Switching from bupivacaine to lidocaine may improve intrathecal morphine analgesia in advanced cancer patients, possibly because of different spinal mechanisms limiting the hyperalgesic processes.
A randomized phase II trial of irinotecan plus carboplatin versus etoposide plus carboplatin treatment in patients with extended disease small-cell l…
2006
Superiority of irinotecan/cisplatin over etoposide/cisplatin was suggested in small-cell lung cancer (SCLC). This trial investigated irinotecan/carboplatin (IP) versus etoposide/carboplatin (EP).The interim analysis at the phase II/phase III transition point of the multicenter trial is reported. Extensive disease SCLC patients were randomized to receive carboplatin AUC 5 mg x min/ml either in combination with 50 mg/m2 of irinotecan on days 1, 8 and 15 (IP) or with etoposide 140 mg/m2 days 1-3 (EP). The primary end point was response rate and the secondary end points were toxicity and progression-free survival.Seventy patients were randomized. Significant differences in grade 3 and 4 thrombo…
Adhesive Small Bowel Obstruction: Predictive Factors of Lack of Response in Conservative Management with Gastrografin
2015
<b><i>Background:</i></b> Gastrografin represents a useful tool in the diagnosis and management of adhesive small bowel obstruction (ASBO). The aim of this study is to identify variables with negative influence in nonoperative management with gastrografin. <b><i>Methods:</i></b> From August 2008 to March 2013, 223 consecutive patients with 235 episodes of ASBO were included and received gastrografin. A protocol for prospective data collection was developed. In order to explore factors related to the failure of nonoperative treatment, univariate and multivariate analysis were performed. <b><i>Results:</i></b> One hundred…
Multiple pregnancies and air pollution in moderately polluted cities: Is there an association between air pollution and fetal growth?
2018
Background: Multiple pregnancies (where more than one fetus develops simultaneously in the womb) are systematically excluded from studies of the impact of air pollution on pregnancy outcomes. This study aims to analyze, in a population of multiple pregnancies, the relationship between fetal growth restriction (FGR), small for gestational age (SGA) and exposure to air pollution in moderately polluted cities. Methods: All women with multiple pregnancies living in the city of Besançon or in the urban area of Dijon and who delivered at a university hospital between 2005 and 2009 were included. FGR and SGA were obtained from medical records. Outdoor residential nitrogen dioxide (NO2) exposure wa…
Correlation between fecal calprotectin and inflammation in the surgical specimen of Crohn's disease
2016
Background: An accurate assessment of the inflammatory activity is crucial to establish the most appropriate treatment in Crohn's disease (CD). The present study aimed to evaluate the utility of preoperative fecal calprotectin (FC) measurement in small bowel CD and its relationship with inflammatory activity in surgical pathology specimens. Methods: This was a prospective observational study including all the patients with small bowel CD operated on at our center between March 2011 and September 2013. Preoperative laboratory and stool tests were performed. A meticulous exploration of entire small bowel was performed during surgery, and the resected bowel (or a sample of whole intestinal wal…
