1 was a recurrence positioned on a surgical anastomosis. Five lesions have been located within the cecum,seven in the ascending colon,two within the transverse colon,1 inside the descending colon,1 within the sigmoid colon and 3 inside the rectum. In lesions ( the resection was performed en bloc,whereas ( have been removed by piecemeal resection. At the pathological examination six lesions had non sophisticated histology,lesions had sophisticated histology and have been SSA,one particular of which with high grade dysplasia. Complete resection was observed in each of the sixteen lesions removed en bloc. A complication (intraprocedural bleeding,endoscopically managed with no consequences) was observed inside the very first two UEMR. Conclusion: UEMR seems a simple,safe and helpful approach also in community setting. Further studies comparing UEMR and standard EMR in terms of total resections and evaluating the early and late recurrence are required. References . Binmoeller KF,Weilert F,Shah J,et al.

Colonoscopy remains the investigation of choice for both diagnosis and screening,and quite a few nations have implemented screening programmes to allow for early detection. The European Society of Gastrointestinal Endoscopy excellent in colonoscopy position statement highlights key excellent indicators in colonoscopy and concluded that the success of screening programmes is associated for the prompt provision of top quality,patient centred colonoscopy service. The European Colonoscopy Top quality Investigation (ECQI) group of leading European clinicians created a sensible tool to enable audit of existing clinical practice across Europe to assess irrespective of whether quality requirements are being accomplished,and to determine,test,and implement sensible ways of improving good quality PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/19389808 in colonoscopy. Aims Techniques: The aim was to know how quality is evaluated in existing clinical practice by means of the development and implementation of an internet tool to audit colonoscopy practice. At the inaugural meeting in ,the ECQI group encouraged a clinical practice level audit tool to become created to allow colonoscopists to audit their very own practice. The audit tool.
