ABSTRACT

PURPOSE: While many factors have been correlated with lesser outcomes in abdominal wall reconstruction (AWR), the impact of surgeon experience has yet to be elucidated. We sought to evaluate the effect of cumulative surgeon experience on long-term complex AWR outcomes. METHODS: We conducted a comprehensive review of all consecutive patients who underwent AWR using biologic mesh for the repair of ventral hernias or tumor resection defects from March 2005 to June 2019. The primary outcome measure was hernia recurrence (HR). Secondary outcomes were surgical site occurrences (SSOs) and surgical site infections (SSIs). Patients were a priori categorized into the following groups according to the cumulative number of hernia repairs performed by their surgeons: low (< 50), moderate experience (50-100), and high (> 100) experience. RESULTS: We identified 60 surgeons and 650 consecutive patients (62% women) who met our inclusion criteria. In adjusted models, AWR performed by surgeons with high experience was associated with a fourfold lower risk of HR (hazard ratio, 0.28; 95% confidence interval, 0.08 to 0.87), but the odds of surgical site occurrences (odds ratio, 0.72, 95% confidence interval, 0.34 to 1.52) and surgical site infections (odds ratio, 0.89, 95% confidence interval, 0.26 to 2.86) did not differ significantly in the high-experience group. CONCLUSIONS: High surgical experience, defined as > 100 cumulative hernia repairs, is predictive for markedly lower HR rates in complex AWR. These findings have potential implications for preoperative risk assessment, patient-centered surgeon selection, regulatory oversight, specific referral patterns, designations of centers of excellence, and individual provider or trainee quality improvement.

ABSTRACT

The influence of fluoride emissions from a modern aluminum smelter on concentrations of skeletal fluoride and dental fluorosis in a resident population of white-tailed deer was studied. The smelter was located on Mount Holly Plantation in South Carolina, and concentrations of skeletal fluoride in the deer collected at Mount Holly increased approximately five-fold 3 yr after the operation began. Increases in skeletal fluoride of less than two-fold were observed in deer obtained from Medway Plantation which has its nearest boundary 1.6 km from the smelter site. No dental fluorosis was observed in deer collected at Medway Plantation, but mild dental fluorosis was observed in a significant number of deer collected at Mount Holly Plantation. The dental fluorosis that was observed was not associated with incisor wear or with fluoride-induced molar wear. Osteofluorosis of mandibles or metacarpals was not observed in any of the deer obtained from either plantation. The data obtained from this study indicated that the presence of a modern aluminum smelter caused a detectable increase in concentration of skeletal fluoride in the resident population of white-tailed deer, but that no adverse health effects were seen.
