Is complete mesocolic excision oncologically superior to conventional surgery for colon cancer? A retrospective comparative study.

Background: During the last decade, many efforts have been made in order to improve the oncologic outcomes following colonic resection. Complete mesocolic excision (CME) has proved to provide high rates of disease-free and overall survival rates in patients undergoing resection for colonic malignancies. The aim of our study was to further investigate the role of CME in colonic surgery through comparison with a series of conventional resections.

Cognitive task analysis for teaching technical skills in an inanimate surgical skills laboratory.

Background: The teaching of surgical skills is based mostly on the traditional "see one, do one, teach one" resident-to-resident method. Surgical skills laboratories provide a new environment for teaching skills but their effectiveness has not been adequately tested. Cognitive task analysis is an innovative method to teach skills, used successfully in nonmedical fields.
