Abstract
Background: Literature on a potential relationship between surgeon case volume and intra- or postoperative complications after ventral hernia repair remains scarce.
Methods: Patients who underwent ventral hernia repair between 2011 and 2023 were selected from the prospectively maintained French Hernia-Club Registry. Outcome variables were: intraoperative events, postoperative general complications, surgical site occurrences, surgical site infections, length of intensive care unit (ICU), and patient-reported scar bulging during follow-up. Surgeons' annual case volume was categorized as 1-5, 6-50, 51-100, 101-125, and > 125 cases, and its association with outcome volume was evaluated using uni- and multivariable analyses.
Results: Over the study period, 199 titular or temporary members registered 15,332 ventral hernia repairs, including 7869 primary, 6173 incisional, and 212 parastomal hernia repairs. In univariate analysis, surgeons' annual case volume was significantly related with all the postoperative studied outcomes. After multivariate regression analysis, annual case volume remained significantly associated with intra-operative complications, postoperative general complications and length of ICU stay. A primary repair was independently associated with fewer intra- and post-operative complications.
Conclusion: In the present multivariable analysis of a large registry on ventral hernia repairs, higher surgeon annual case volume was significantly related with fewer postoperative general complications and a shorter length of stay, but not with fewer surgical site occurrences, nor with less patient-reported scar bulging. Factors in the surgeons' case mix such as the type of hernia have significant impact on complication rates.
期刊介绍：
Hernia was founded in 1997 by Jean P. Chevrel with the purpose of promoting clinical studies and basic research as they apply to groin hernias and the abdominal wall . Since that time, a true revolution in the field of hernia studies has transformed the field from a ”simple” disease to one that is very specialized. While the majority of surgeries for primary inguinal and abdominal wall hernia are performed in hospitals worldwide, complex situations such as multi recurrences, complications, abdominal wall reconstructions and others are being studied and treated in specialist centers. As a result, major institutions and societies are creating specific parameters and criteria to better address the complexities of hernia surgery.
Hernia is a journal written by surgeons who have made abdominal wall surgery their specific field of interest, but we will consider publishing content from any surgeon who wishes to improve the science of this field. The Journal aims to ensure that hernia surgery is safer and easier for surgeons as well as patients, and provides a forum to all surgeons in the exchange of new ideas, results, and important research that is the basis of professional activity.
