Relationship between surgical volume and clinical outcome: Should pediatric surgeons be doing pancreaticoduodenectomies?

Background: The relationship between surgical volume and clinical outcome is well established in adult pancreatic surgery. We examined whether this relationship is applicable in pediatric surgery, given that very few cases are done regularly by pediatric surgeons even at tertiary centers. Methods: A retrospective analysis of all patients who underwent pancreaticoduodenectomies between 1993 and 2003 was done. Comparisons were made to the largest recent series of pancreaticoduodenectomies in the adult literature. Results: With the age at presentation from 9 to 17 years, 5 patients were identified. Mean operative time was 451 minutes with a median of 363 minutes compared with the mean and median in the adult literature of 420 minutes. Clean margins were obtained in all patients compared with 71% in adults. Mean follow-up was 35 months. All patients are alive, with 1 patient who has underwent subsequent resections for local recurrence. Conclusion: Although 5 consecutive cases of pancreaticoduodenectomies represent very low volume compared with high-volume adult centers, minimal difference in operative time, length of stay, and mortality (none) were observed in this series. Therefore, unlike adults, particular case volume in the pediatric population may not be a significant factor because of the nature of pancreatic pathology, patient characteristics, and hospital and surgical environment.
