ENDOSCOPIC PROCEDURES FOR COLORECTAL ANASTOMOSES STRICTURES (review)

In the review data concerning modern methods of endoscopic treatment of colonic strictures are presented.Relevance of this problem, reasons for the development, clinical picture and methods of endoscopic procedures for strictures are presented in detail.The analysis of Russian and foreign literature with an assessment of the effectiveness and feasibility of various methods of treatment of strictures has been done. Despite the variety of ways of existing methods of stricture’s treatment, there are still no evidence-based data on the efficiency and safety of various endoscopic approaches.Thus, there are a number of unresolved topical issues that require further research.

Endoscopic surveillance strategies for dysplasia in ulcerative colitis

Ulcerative colitis (UC) is a chronic inflammatory bowel disorder with an increased risk of colorectal cancer (CRC). This has led to the implementation of surveillance programmes to minimise this risk. Overall, these proactive programmes in association with better medical therapies have reduced the incidence of CRC in this population. Specific populations remain at increased risk, such as younger age at diagnosis, primary sclerosing cholangitis, colonic strictures and pseudopolyps. The majority of gastrointestinal international societies favour chromoendoscopy with targeted biopsies or random biopsies. The aim of this review is to present the current literature on dysplasia surveillance, the methodology and endoscopic technology available to assess dysplasia in UC.
