Fish consumption is associated with a reduced colorectal cancer risk. A possible mechanism by which fish consumption could decrease colorectal cancer risk is by reducing inflammation. However, thus far, intervention studies investigating both systemic and local gut inflammation markers are lacking. Our objective in this study was to investigate the effects(More)
OBJECTIVE The introduction of anti tumour necrosis factor-α (anti-TNFα) therapy might impact healthcare expenditures, but there are limited data regarding the costs of inflammatory bowel diseases (IBD) following the introduction of these drugs. We aimed to assess the healthcare costs and productivity losses in a large cohort of IBD patients. DESIGN(More)
BACKGROUND & AIMS Two percent to 4% of all cases of colorectal cancer (CRC) are associated with Lynch syndrome. Dominant clustering of CRC (non-Lynch syndrome) accounts for 1%-3% of the cases. Because carcinogenesis is accelerated in Lynch syndrome, an intensive colonoscopic surveillance program has been recommended since 1995. The aim of the study was to(More)
BACKGROUND Diet is a major factor in the etiology of colorectal cancer, with high fish consumption possibly decreasing colorectal cancer risk, as was shown in several observational studies. To date, no intervention trials have examined the possible beneficial effects of fish intake on colorectal cancer risk. OBJECTIVE The objective was to investigate the(More)
BACKGROUND AND STUDY AIMS Direct endoscopic retrograde cholangiopancreatography (ERCP) has become the standard for establishing the diagnosis of primary sclerosing cholangitis (PSC), while endoscopic procedures play an increasingly important therapeutic role. However, many believe that this procedure carries a significant risk of infection and other(More)
Laparoscopic sleeve gastrectomy (LSG) is effective as a stand-alone bariatric procedure. Despite its positive effect with regard to weight loss and improvement of obesity-related co-morbidities, some patients develop gastroesophageal reflux symptoms postoperatively. The pathogenesis of these symptoms is not completely understood. Hence, this study aimed to(More)
BACKGROUND Incidence rates of both obesity and gastro-oesophageal reflux disease (GERD) are increasing, particularly in the Western world. It has been suggested that GERD symptoms may be improved by weight reduction. AIM To review the literature on the effect of various weight reducing modalities on manifestations of GERD in obese patients. METHODS A(More)
Extracorporeal shock-wave lithotripsy (ESWL) is an effective treatment in selected gallstone patients, but stone recurrence is a major drawback. Factors potentially influencing gallstone clearance and recurrence were studied in 84 patients in whom stone dissolution was diagnosed after ESWL plus bile salt therapy for initial solitary (n = 55) or multiple (n(More)
BACKGROUND/AIMS Ursodeoxycholic acid has been reported to be of potential benefit for primary sclerosing cholangitis but little is known about the long-term biochemical, histological and radiological efficacy or the optimum frequency of ursodeoxycholic acid administration. METHODS A 2-year multicentre randomised controlled trial was initiated to assess(More)
BACKGROUND Ursodeoxycholic acid (UDCA) is beneficial in cholestasis related to cystic fibrosis (CF). High-dose treatment has been recommended to compensate for bile salt malabsorption. We compared the results of low-dose (10 mg/kg/day) and high-dose (20 mg/kg/day) UDCA treatment on liver biochemistry after 3 and 12 months' treatment. METHODS Thirty CF(More)
