Minimally invasive surgical exposure among US and Canadian pediatric surgery trainees, 2004-2016

Abstract

BackgroundMinimally invasive pediatric surgery has increased in breadth and complexity over the past several decades, with little data on minimally invasive surgery (MIS) training in US and Canadian pediatric surgery fellowship programs. MethodsWe performed a time series analysis of Accreditation Council for Graduate Medical Education pediatric surgery fellow case logs from 2003 to 2016. Proportions of cases performed in an MIS fashion as well as per-fellow MIS case averages were recorded over time. ResultsThere was a 30.9% increase in average number of MIS cases per fellow over the study time period. Twenty-three recorded procedures included MIS and open options (17 abdominal, three thoracic, and three genitourinary). The proportion of cases performed using a minimally invasive approach increased by an average of 29.0%, 14.6%, and 47.0% for each of these categories, respectively. Significant variability was observed in specific cases such as laparoscopic and open inguinal hernias, ranging from 0 to 85 and nine to 152 per trainee, respectively, in the final year of data collection. When examining pyloromyotomy, a high-volume procedure with a known increase in the MIS approach, the proportion of cases performed MIS increased by 83.3%. The minimum and maximum number of cases per fellow recorded ranged from 0 to 114 during the eight years in which MIS pyloromyotomy was recorded. ConclusionsMIS case exposure among graduating US and Canadian pediatric survey fellows increased substantially during the study period. More granular data, however, are needed to better define the current operative experience and criteria for determination of competency in advanced MIS.
