Comparative Study
Robotic-Assisted Transperitoneal Pelvic Lymphadenectomy for Metastatic Melanoma: Early Outcomes Compared with Open Pelvic Lymphadenectomy.
In the absence of iliac or obturator nodal involvement, the role of pelvic lymphadenectomy (PLND) for melanoma is controversial, but for select patients, long-term survival can be achieved with the combination of superficial inguinal (inguinofemoral) and PLND. Open PLND (oPLND) is often limited in visual exposure and can be associated with considerable postoperative pain. Robotic PLND (rPLND) is a minimally invasive technique that provides excellent visualization of the iliac and obturator nodes. Outcomes comparing the open and robotic techniques have not been reported previously for patients with melanoma. ⋯ Robotic PLND offers a safe, effective, minimally invasive approach to resect the pelvic lymph nodes in patients with melanoma, with no significant difference in nodal yield or operative times, but a shorter length of stay compared with oPLND.

A significant number of patients undergo endovascular repair of abdominal aortic aneurysms (EVAR) outside the instructions for use (IFU). This study will examine various aortic neck features and their predictors of clinical outcomes. ⋯ Patients with neck features outside IFU can be treated with EVAR; however, they have higher rates of early and late type I endoleak, early intervention, and late death.

Current methods to predict patients' perioperative morbidity use complex algorithms with multiple clinical variables focusing primarily on organ-specific compromise. The aim of the current study was to determine the value of a timed stair climb in predicting perioperative complications for patients undergoing abdominal surgery. ⋯ Stair climb provides measurable stress, accurately predicts postoperative complications, and is easy to administer in patients undergoing abdominal surgery. Larger patient populations with a diverse group of operations will be needed to validate the use of stair climbing in risk-prediction models.

The Cancer and Leukemia Group B (CALGB) 9343 trial demonstrated that adjuvant radiation therapy (RT) can be omitted in women aged 70 years or older, with small, estrogen receptor (ER)+ breast cancer. We postulated that RT usage after CALGB's publication should have decreased over time. ⋯ The CALGB trial had a minimal impact on the rate of adjuvant RT use among elderly women with small, hormone positive breast cancers. Significant variation in RT usage exists across sociodemographic strata.

The initial experience with ABO incompatible (ABOi) orthotopic liver transplantations (OLTs) was dismal. In the current study, we investigated whether ABOi pediatric OLTs could achieve acceptable patient outcomes. The option for ABOi transplantation is vital because critically ill children have limited access to donor liver allografts. ⋯ This analysis revealed a significant improvement in the survival of ABOi liver transplant recipients in the modern era. Importantly, ABOi liver transplantation can be performed in recipients younger than 2 years of age with equivalent outcomes compared with ABO-identical recipients.
