A single was a recurrence located on a surgical anastomosis. Five lesions were located in the cecum,seven inside the ascending colon,two inside the transverse colon,one particular within the descending colon,one particular inside the sigmoid colon and 3 in the rectum. In lesions ( the resection was performed en bloc,whereas ( were removed by piecemeal resection. In the pathological examination six lesions had non advanced histology,lesions had sophisticated histology and had been SSA,1 of which with high grade TSH-RF Acetate web dysplasia. Comprehensive resection was observed in all of the sixteen lesions removed en bloc. A complication (intraprocedural bleeding,endoscopically managed with no consequences) was observed in the first two UEMR. Conclusion: UEMR appears an easy,safe and effective strategy also in neighborhood setting. Further research comparing UEMR and traditional EMR in terms of full resections and evaluating the early and late recurrence are needed. References . Binmoeller KF,Weilert F,Shah J,et al.

Colonoscopy remains the investigation of decision for each diagnosis and screening,and quite a few countries have implemented screening programmes to enable for early detection. The European Society of Gastrointestinal Endoscopy high-quality in colonoscopy position statement highlights essential good quality indicators in colonoscopy and concluded that the achievement of screening programmes is associated towards the prompt provision of top quality,patient centred colonoscopy service. The European Colonoscopy Top quality Investigation (ECQI) group of leading European clinicians developed a practical tool to allow audit of current clinical practice across Europe to assess whether high quality standards are becoming achieved,and to recognize,test,and implement practical strategies of enhancing high quality PubMed ID:https://www.ncbi.nlm.nih.gov/pubmed/19389808 in colonoscopy. Aims Techniques: The aim was to know how high quality is evaluated in current clinical practice through the improvement and implementation of an online tool to audit colonoscopy practice. At the inaugural meeting in ,the ECQI group suggested a clinical practice level audit tool to become developed to allow colonoscopists to audit their very own practice. The audit tool.
