[Teaching in the operative room: the benefit of daysurgery on surgical trainees]. / Attività didattica in sala operatoria: utilità della day-surgery nell'iter formativo dello specializzando in chirurgia.

AIM: Aim of the study was to evaluate the operative time and the incidence of post-operative complications in a group of patients undergoing Lichtenstein inguinal hernia repair performed either by surgical residents or senior surgeons in a day-surgery setting. PATIENTS AND METHODS: The study population consisted of 198 patients: group I (n=102), in which the operator was a senior surgeon, group II (n=96), in which the operator was a resident supervised by a senior surgeon. We recorded the duration of the operation and the complications following the procedure, and statistically compared them between group I and II. RESULTS: Our analysis showed that there was a statistically significant difference between the two groups only for the mean operative time, being shorter in group I (62 vs 82 min, p>0.05), while no significant difference was found for the incidence of complications. CONCLUSION: In conclusion, the day-surgery setting allows a high quality training of young surgeons, based on performing minor surgical procedures such has inguinal hernia repair. This training allows a step by step supervised learning process that does not jeopardize the efficacy of the treatment as well as the patient safety. The major cost due to the increase in operative time should be considered as an investment in young surgeons education.
