The aim of this study was to use recent evidence to investigate and update volume-outcome relationships after open surgical repair (OSR) and endovascular repair (EVAR) of abdominal aortic aneurysm in England. ⋯ Higher annual all-procedure volumes were associated with significantly lower in-hospital mortality for OSR, but such a relationship was not significant for EVAR. There was not enough evidence for a volume effect on other outcomes.

Prepectoral implant-based breast reconstruction with acellular dermal matrix has become an increasingly popular option for selected patients. There are no randomized data to demonstrate short- or long-term outcomes. Cohort studies to date have demonstrated safety, but risk factors for complications are unknown. ⋯ Prepectoral implant-based breast reconstruction has acceptable medium-term results but careful patient selection is advised.
