BACKGROUND Lynch syndrome is a disorder caused by mismatch repair gene mutations. Mutation carriers have a high risk of developing colorectal cancer. In patients with Lynch syndrome in whom colon cancer has been diagnosed, in general, subtotal colectomy instead of partial colectomy is recommended because of the substantial risk of metachronous colorectal(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)
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 & 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)
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)
During treatment with ursodeoxycholic acid (UDCA), the fasting gallbladder volume increases by a yet unknown mechanism. The present study tests whether in vitro human gallbladder contractility in response to acetylcholine and cholecystokinin is affected by UDCA therapy. Gallbladder tissue was obtained from 15 patients treated with UDCA (10 mg/kg/day) during(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)
INTRODUCTION Lynch syndrome families have a substantial risk of developing colorectal cancer (CRC). The recommended surveillance protocol includes colonoscopy every 2 years from age 20-25 years. It is yet unknown whether annual screening of patients aged 40-60 years is more effective than bi-annual screening, whether patients who had an adenoma removed(More)
BACKGROUND Ursodeoxycholic acid (UDCA) improves liver biochemistry in primary biliary cirrhosis (PBC) and primary sclerosing cholangitis (PSC). Since UDCA acts partly by reducing the intestinal absorption of hydrophobic endogenous bile salts and is poorly absorbed from the intestine, a multiple dose regimen has been advocated. Single dose treatment, on the(More)
BACKGROUND & AIMS Seventy percent of patients with primary sclerosing cholangitis (PSC) have concomitant ulcerative colitis. Smoking and previous appendectomy may protect against ulcerative colitis. The aim of this study was to examine these factors in patients with PSC. METHODS Fifty-nine patients with PSC, 130 patients with ulcerative colitis and normal(More)
