Colorectal breast carcinoma metastasis diagnosed as an obstructive colonic primary tumor. A case report and review of the literature.

Common sites of colorectal breast carcinoma metastasis are bones, lungs, the central nervous system and the liver. Metastases in the gastrointestinal (GI) tract are rare and especially involve the stomach rather than the colon. Clinical or radiological features usually cannot differentiate them from a primary colorectal tumor, resulting in inappropriate treatment. In some cases, this lesion suggests multifocal spread of breast cancer with peritoneal carcinomatosis. Colorectal breast cancer metastasis is a rare finding and there is no consensus on the management of these lesions. The present case report describes a 69-year-old female with metastatic breast cancer presenting as an obstructive tumor of the transverse colon.

French intensive training course in laparoscopic surgery (HUGOFirst) on live porcine models: Validation of a performance assessment scale and residents' satisfaction in a prospective study.

INTRODUCTION: Simulation as a method for practical teaching of surgical residents requires objective evaluation in order to measure the student's acquisition of knowledge and skills. The objectives of this article are to publish our evaluation and validation grids and also the measure of student satisfaction. METHOD: A teaching platform based on practical exercises with a porcine model was created in 2009 at seven French University Hospitals. Three times a year, 31 Diplôme d'Études Spécialisées Complémentaires (DESC) surgical residents underwent timed assessment of the performance of five surgical tasks: trocar insertion (trocars) testing the convergence of instruments (convergence), intra-corporeal knot tying (knots), running of the small intestine to find a lesion (exploration), and performance of a running suture closure of the peritoneum (closure). Two experts evaluated performances prospectively on grid score sheets specifically designed and validated for these exercises. We measured time, scores on a rating scale, and the interest and satisfaction of the residents. RESULTS: Data for 31 residents between May 2011 and March 2012 were analyzed. Rating scales were statistically validated and correlated (Kappa correlation coefficient K>0.69) for each task. The performance times of the most experienced residents decreased significantly for all tasks except for small bowel exploration (P=0.2). After four sessions, times were significantly improved with better quality (fewer errors and higher average scores [>88%]), regardless of the residents' experience. Of the participants, 92% were satisfied, 86% thought that the sessions improved their technical skills and 74% thought it had a favorable impact on their clinical practice. CONCLUSION: This study shows that the performance of surgical techniques can be improved through simulation, that HUFEG grids are valid, and that this teaching program is popular with surgical residents.
