Association of hospital and surgeon operative volumes and surgeon pediatric subspecialization with pediatric laparoscopic cholecystectomy outcomes: A population-based cohort study

Background: Most pediatric cholecystectomies are performed by adult general surgeons, but it is unclear whether outcomes differ by surgeon pediatric subspecialization, hospital procedure volume, or surgeon procedure volume. We aimed to determine whether higher hospital or surgeon laparoscopic cholecystectomy (LC) volume or surgeon pediatric subspecialization is associated with better outcomes after LC in children.

Methods: We performed a retrospective cohort study using statewide hospital discharge databases from the states of Florida, Georgia, and Iowa. We included children aged 4-18 years who underwent inpatient or outpatient LC for acute or chronic gallbladder disease in January 2010-August 2015. Propensity score weighting was used to estimate relationships between operative volumes or surgeon pediatric subspecialization and rates of readmission or emergency department (ED) visit within 30 days.

Results: A total of 5391 children were included (mean age 15.9 years, 81.6% female). Children operated on by surgeons with high LC volumes in hospitals with high LC volumes were less likely to experience a readmission or ED visit within 30 days (10.8% vs. 13.7%, p = 0.04). Additionally, children operated on by adult general surgeons in hospitals with high LC volumes were less likely to experience a readmission or ED visit within 30 days (10.9% vs. 13.8%, p = 0.03).

Conclusions: Children are less likely to be readmitted to the hospital or present to the ED after laparoscopic cholecystectomy if they receive their care from adult general surgeons at hospitals that frequently perform this procedure in both adults and children.

Level of evidence: III.
