Cohesin is present in almost all active enhancer regions, where it is associated with transcription factors. Cohesin frequently colocalizes with CTCF (CCCTC-binding factor), affecting genomic stability, expression and epigenetic homeostasis. Cohesin subunits are mutated in cancer, but CTCF/cohesin-binding sites (CBSs) in DNA have not been examined for(More)
PURPOSE The aim of the study was to calculate the cumulative occurrence of pouch failure among 486 patients who had undergone proctocolectomy and ileoanal anastomosis for ulcerative colitis or familial adenomatous polyposis. The other goal was to compare the quality of life in the failure group of 21 patients, the successful group, and the healthy(More)
BACKGROUND AND STUDY AIMS Patients with familial adenomatous polyposis (FAP) are at increased risk for duodenal cancer whereas colorectal cancer is largely prevented by prophylactic colectomy. We analyzed the results of endoscopic surveillance and different treatment modalities of duodenal adenomatosis in patients with FAP. PATIENTS AND METHODS Data on(More)
BACKGROUND The aim of this study was to calculate the probability of becoming pregnant after ileal pouch-anal anastomosis (IPAA) for ulcerative colitis, and to evaluate complications during pregnancy and childbirth. METHODS A questionnaire was posted to 160 women with an IPAA and to 160 controls. The probability of becoming pregnant after IPAA was(More)
BACKGROUND & AIMS Peutz-Jeghers syndrome (PJS) is typically manifested as severe gastrointestinal polyposis. Polyps in PJS patients and in Lkb1(+/-) mice that model PJS polyposis are frequently characterized by elevated cyclooxygenase-2 (COX-2). This study was designed to determine whether COX-2 inhibition would reduce tumor burden in Lkb1(+/-) mice or(More)
PURPOSE The prevalence of primary sclerosing cholangitis (PSC) among patients with ulcerative colitis needing proctocolectomy is about 12%. The study aim was to evaluate the progression of the liver disease after surgery. METHODS PSC progression in 68 patients with UC after restorative proctocolectomy was evaluated after a median follow-up of 11 years(More)
AIM We evaluated the outcome of patients with pseudomyxoma peritonei (PMP) after traditional debulking. PMP is a clinical condition characterized by disseminated intraperitoneal mucinous tumours often accompanied by mucinous ascites derived usually from an appendiceal neoplasm. Patients with PMP have traditionally been treated by serial debulking, but(More)
BACKGROUND Gastric outlet obstruction (GOO) commonly occurs in advanced gastric cancer. Our aim was to evaluate the results of endoscopic stenting (ES), palliative resection (PR), and gastrojejunostomy (GJ) as palliation of GOO. METHODS A total of 97 patients (50 ES, 26 PR, 21 GJ) were included in this retrospective study. All the patients had primary(More)
AIM Duodenal adenomatosis in familial adenomatous polyposis results in a cancer risk that increases with age. Endoscopic surveillance has been recommended, but the effect has not yet been documented. The aim of this study was to present the results of long-term duodenal surveillance and to evaluate the risk of cancer development. METHOD Follow up of(More)
OBJECTIVE Self-expanding metal stents (SEMS) have been successfully used as a "bridge to surgery" or as palliation for acute malignant colorectal obstruction. Little data on the use of stents for benign obstruction exists and the results vary. The purpose of this study was to evaluate the efficacy and safety of SEMS in benign colorectal obstruction. (More)
