Surgical excision is currently recommended after pathologic radial scar is found on breast core needle biopsy because surgical upgrade to carcinoma is not uncommon. The goal of our study was to identify the true pathologic upgrade rate for a "pure" radial scar, those without associated proliferative lesion, based on indication for biopsy, biopsy type, and needle size. ⋯ Surgical excision is unnecessary when radial scar is found at percutaneous needle biopsy without an associated proliferative lesion. Surgical excision is still indicated when radial scar is associated with atypical ductal hyperplasia or lobular neoplasia.

Randomized Controlled Trial Comparative Study
Randomized clinical trial of oral and intravenous versus intravenous antibiotic prophylaxis for laparoscopic colorectal resection.
The use of oral prophylactic antibiotics for the prevention of surgical-site infection (SSI) in patients undergoing laparoscopic surgery for colorectal cancer is controversial. The aim of this RCT was to evaluate whether intravenous perioperative antibiotics are inferior to combined preoperative oral and perioperative intravenous antibiotics in this setting. ⋯ Intravenous perioperative antimicrobial prophylaxis alone is not inferior to combined preoperative oral and intravenous perioperative prophylaxis with regard to SSI in patients with colorectal cancer undergoing elective laparoscopic resection.
