Congenital stenosis of the colon with foreign bodies. Case report.

Background: Colonic stenosis is rarely seen in pediatric practice. Its incidence has been reported as 1/40,000 births. Ascending and transverse colon are the most common sites affected.

[Biosimulator training and its impact on skill in laparoscopic cholecystectomy].

Objective: We undertook this study to determinate the educational impact of training in an inanimate biosimulator in terms of effectiveness, time and complications in performing laparoscopic cholecystectomy.

Methods: We used a comparative, experimental cohort, prospective and longitudinal. Three first-postgraduate-year residents and one pre-grade internship physician were trained and assessed in basic laparoscopic skills using a biosimulator (fiberglass "dummy" where animal organs are introduced ex-vivo).
