The Acute Colonic Pseudo-Obstruction (ACPO), also known as Ogilvie's syndrome, is defined by a poor peristaltic activity of the colon that mimics mechanical obstruction in the absence of any mechanical occlusive gut lesion. This case report is the first to be published on ACPO following a robotic- assisted radical hysterectomy. Since robotic-assisted laparoscopic surgery has become the next major stage of advancement for a range of operations especially in gynecologic oncology surgery, this report emphasizes the importance of recognizing precipitating factors associated with this syndrome, including minimally invasive surgery...

Surgery is still the main treatment in early-stage of non-small cell lung cancer with 5-year survival of stage IA patients exceeding 80%, but 5-year survival of stage II patients rapidly decreasing with tumor size, N status, and visceral pleura invasion. The major metastatic risk in such patients has supported clinical research assessing systemic or loco-regional perioperative treatments. Modern phase 3 trials clearly validated adjuvant or neo-adjuvant platinum-based chemotherapy in resected stage I-III patients as a standard treatment of which value has been reassessed several independent meta-analyses, showing a 5% benefit in 5y-survival, and a decrease of the relative risk for death around from 12 to 25%...
