RESUMO

BACKGROUND: More data regarding complications in neurosurgery residents' cases are needed to assess patients' safety during hands-on surgical education. METHODS: A retrospective 2-center study was performed comparing consecutive patients undergoing shunt implantation by a supervised neurosurgery resident (teaching cases) versus a board-certified faculty neurosurgeon (nonteaching cases). The primary end point was surgical revision after shunting. Univariate and multivariate Cox proportional hazard models (Breslow method for ties) with time censored at 2 years were used to examine time-to-event data. Operation time, length of hospitalization, intracranial hemorrhage, and misplacement of the shunt catheter were other outcome measures to be compared between the groups. RESULTS: A total of 320 shunts (180 [56.3%] teaching and 140 [43.7%] nonteaching cases) with a mean follow-up of 563 ± 771 days (standard deviation) were analyzed. Revision rates for the entire cohort were 9.3% at 90 days, 13.3% at 6 months, 18.4% at 1 year, and 26.5% at 2 years. In univariate analysis, teaching cases were 96% as likely as nonteaching cases to be surgically revised (hazard ratio, 0.96; 95% confidence interval, 0.54-1.70; P = 0.877). In multivariate analysis adjusted for indication and shunt type, teaching cases were 94% as likely as nonteaching cases to undergo surgical revision (hazard ratio, 0.94; 95% confidence interval, 0.53-1.69; P = 0.847). There were no group differences in operation time, length of hospitalization, intracranial hemorrhage, and rates of shunt misplacement. CONCLUSIONS: The results of the current study in addition to the literature on neurosurgery resident training support the safety of supervised early surgical education for shunt surgery.
