Postoperative pancreatic fistula is the main driver of morbidity and mortality after pancreatoduodenectomy. In high-risk patients, the rate of postoperative pancreatic fistula approaches 50%, whereas it is below 5% in patients with pancreatic cancer who receive neoadjuvant chemoradiotherapy. The aim of this study was to evaluate the safety, feasibility, and efficacy of preoperative stereotactic body radiotherapy on the pancreatic neck transection margin in high-risk patients undergoing pancreatoduodenectomy to prevent postoperative pancreatic fistula. ⋯ Preoperative stereotactic body radiotherapy is safe in high-risk patients undergoing pancreatoduodenectomy and increases parenchymal firmness and fibrosis, but fails to show evidence of efficacy.

Oncoplastic breast-conserving surgery may be a better option than mastectomy, but high-quality comparative evidence is lacking. The aim of the ANTHEM study (ISRCTN18238549) was to explore clinical and patient-reported outcomes in a multicentre cohort of women offered oncoplastic breast-conserving surgery as an alternative to mastectomy with or without immediate breast reconstruction. ⋯ Oncoplastic breast-conserving surgery allows greater than 95% of women to avoid mastectomy, with lower major complication rates than immediate breast reconstruction, and may improve satisfaction with outcome. Oncoplastic breast-conserving surgery should be offered as an alternative to mastectomy in all women in whom it is technically feasible.

Chest wall perforator flaps are safe and can decrease mastectomy rates in breast cancer surgery: multicentre cohort study.
Chest wall perforator flaps are emerging in oncoplastic breast conservation, mostly as an alternative to mastectomy. However, standardization and consensus on patient selection, techniques, and outcomes have not yet been reached. The aim of this international multicentre collaborative study was to explore practice patterns and outcomes in high-volume centres from different countries. ⋯ Chest wall perforator flaps are a useful option to allow more women to avoid mastectomy. In experienced hands, the procedure is safe and should be offered to suitable patients.

Identification of patient characteristics that may improve procedure selection for the treatment of carotid stenosis.
Carotid endarterectomy and carotid artery stenting are common procedures for the treatment of carotid artery stenosis. The aim of this study was to identify factors that modify the effect between type of treatment and outcome, and could thus be used to refine the selection of treatment procedure. ⋯ This analysis shows that carotid artery stenting may be particularly disadvantageous in older patients, in patients with right-sided stenosis, and in symptomatic patients treated within the first 2 days after the index event. In patients with contralateral occlusion, carotid artery stenting appears equivalent to carotid endarterectomy.
