Minimally invasive esophagectomy is emerging with comparable short-term outcomes as open esophagectomies. Neoadjuvant chemoradiotherapy followed by surgery is considered standard of care in the Netherlands for patients with esophageal cancer. The aim of this study was to analyze the long-term oncologic outcome after neoadjuvant chemoradiotherapy followed by totally minimally invasive esophagectomy. ⋯ Totally minimally invasive esophagectomy after neoadjuvant chemoradiotherapy for esophageal cancer is a safe treatment with low postoperative mortality rates and favorable overall and disease-free survival.

This study evaluated the relationship between the maximum standardized uptake value (SUVmax) of preoperative positron emission tomography/computed tomography (PET/CT) and the characteristics of lung adenocarcinoma featuring ground-glass opacity nodules (GGN). ⋯ The SUVmax of lung adenocarcinoma featuring GGN can vary depending on the GGO proportion. A higher SUVmax can be expected in invasive adenocarcinoma than in MIA, and solid and acinar-predominant invasive adenocarcinoma showed a higher SUVmax.

Despite neoadjuvant chemoradiation (nCRT) followed by esophagectomy for locally advanced esophageal cancer, locoregional recurrence (LRR) is common and factors associated with LRR have not been clearly identified. ⋯ Although aggressive tumor biology plays a significant role in LRR, optimizing neoadjuvant treatments to obtain a complete pathologic response may lead to improved locoregional control.

Effective and efficient lymphaticovenular anastomosis using preoperative ultrasound detection technique of lymphatic vessels in lower extremity lymphedema.
Identification of functional lymphatic vessels and localization of lymphatic vessels are important for lymphaticovenular anastomosis (LVA). Indocyanine green (ICG) lymphography is useful for localization of superficial lymphatic vessels where dermal backflow is not observed, but not for lymphatic vessels in deep layer or where dermal backflow is observed. Ultrasound has been applied in LVA and is considered useful for localization of lymphatic vessels with ICG lymphography cannot be visualized. ⋯ Ultrasound-guided detection of lymphatic vessels for lymphedema was performed with high precision, and allows easier and more effective LVA surgery.

To develop and validate a nomogram to estimate the pretest probability of malignancy in Chinese patients with solid solitary pulmonary nodule (SPN). ⋯ We developed and validated a nomogram that can estimate the pretest probability of malignant solid SPNs, which can assist clinical physicians to select and interpret the results of subsequent diagnostic tests.
