BACKGROUND: Most Crohn's disease (CD) patients develop endoscopic recurrence within one year of intestinal resection. The best treatment method to prevent post-operative CD recurrence remains uncertain. METHODS: A total of 155 CD patients from 2 referral centres, who were undergoing intestinal resection with ileo-colonic anastomosis (January 2004-January 2015), were included. All subjects received preventive therapy with tumour necrosis factor antagonists (anti-TNFs), thiopurinesor mesalazine...

BACKGROUND/AIMS: We aimed to evaluate the prognostic factors that can aid in the prevention of first and second surgeries in patients with Crohn's disease (CD). METHODS: The clinical records of 115 patients with CD whose disease onset was between January 1987 and July 2012 were retrospectively investigated. The cumulative rate of bowel resection for CD-related intestinal manifestations following onset until the first surgery and the cumulative rate of reoperation following the first to second surgeries were estimated using the Kaplan-Meier method, and the relationship to each factor was statistically analyzed using the log-rank test...

INTRODUCTION: Duodenal polyps and especially duodenal adenomas are a rare and mostly coincidental finding in patients undergoing upper gastrointestinal endoscopy. Due to their malignant potential, duodenal adenomas should be removed upon diagnosis. So far, the limited available data on the performance of endoscopic polypectomy show conflicting results with regard to adverse events and the adenoma recurrence rate. PATIENTS AND METHODS: After summarizing the currently available data, we retrospectively analyzed all patients undergoing endoscopic resection of nonampullary duodenal adenomas (NAD) at our institution between 2006 and 2016...

BACKGROUND/AIMS: In patients with active ulcerative colitis (UC), pharmacologics, although initially effective in most patients, are associated with refractoriness, loss of response or unfavourable side effects as additional morbidity factors. Depletion of myeloid lineage leucocytes like the CD14(+)CD16(+) monocyte phenotype, which is a major source of tumour necrosis factor-α, by granulocyte/monocyte apheresis (GMA) if effective, is also known to be free from side effects. METHODS: In clinical practice setting, 77 consecutive patients with moderate to severe UC, who failed to respond to first-line medications received GMA with the Adacolumn as remission induction therapy...

BACKGROUND: Pancreatic neuroendocrine tumors (PNETs) are rare neoplasms accounting for less than 5% of all pancreatic malignancies. These tumors are characterized by clinical and prognostical heterogeneity and are predominantly diagnosed in a metastatic stage. Cytotoxic chemotherapy, along with alkylating agents and antimetabolites as well as molecular targeted agents (everolimus, sunitinib), is used in the treatment of advanced PNETs. After the approval of lanreotide for unresectable PNETs, an additional therapeutic option has become available; however, the best sequence of therapies and patient stratification to different treatments remains challenging...
