Minimally invasive sublobar anatomical resection is becoming more and more popular to manage early lung lesions. Robotic-assisted thoracic surgery (RATS) is unique in comparison with other minimally invasive techniques. Indeed, RATS is able to better integrate multiple streams of information including advanced imaging techniques, in an immersive experience at the level of the robotic console. Our aim was to describe three-dimensional (3D) imaging throughout the surgical procedure from preoperative planning to intraoperative assistance and complementary investigations such as radial endobronchial ultrasound (R-EBUS) and virtual bronchoscopy for pleural dye marking...

Since 1995, lobar resection became the standard of care for medically fit patients with early stage lung cancer. This was based on the results of a single randomized trial comparing lobectomy and sublobar resection (SLR) in stage I lung cancer conducted by the lung cancer study group between 1982 and 1988. The conclusions of the study included a statistically significant tripling in loco-regional recurrence (LR) after limited resection but no difference between the two arms of the trial in systemic recurrence...

BACKGROUND: Development demand of precise medicine in resectable esophageal squamous cell carcinoma (ESCC) require to recognize patients at high risk treated by surgery alone. Thus, our aim was to construct a clinical nomogram and recursive partitioning analysis (RPA) to predict long-term survival in ESCC treated by surgery alone. METHODS: Based on the patients with ESCC who treated by three-incisional esophagectomy and two-field lymphadenectomy alone, we identified and integrated significant prognostic factors for survival to build a nomogram...

Lateral pancreaticojejunostomy (LPJ), also known as the Puestow procedure, is a complex surgical procedure reserved for patients with refractory chronic pancreatitis (CP) and a dilated pancreatic duct. Traditionally, this operation is performed through an open incision, however, recent advancements in minimally invasive techniques have made it possible to perform the surgery using laparoscopic and robotic techniques with comparable safety. Though we do not have enough data yet to prove superiority of one over the other, the robotic approach appears to have an advantage over the laparoscopic technique in better visualization through 3-dimensional (3D) imaging and availability of wristed instruments for more precise actions, which may translate into superior outcomes...

Mondor's disease (MD) is a rare disease that manifests with a palpable cord-like induration on the body surface. In general, MD is a self-limited, benign thrombophlebitis that resolves in four to eight weeks without any specific treatment. Cases of MD can be roughly categorized into three different groups based on the site of the lesion as follows: original MD of the anterolateral thoracoabdominal wall, penile MD with dorsum and dorsolateral aspects of the penis, and axillary web syndrome with mid-upper arm after axillary surgery...

Greater life expectancy with advancements in technology and medicine has led to an increasing interest in facial rejuvenation. Facial aging is an inevitable process that largely results from soft tissue descent and volumetric deflation. However, a comprehensive knowledge of the aging process and precise assessment of the exact pathologies yielding the patient's senescent appearance is essential to produce the best cosmetic outcome. The surgeon must evaluate each region independently and the aging face as a whole to ensure a pleasing, natural appearance...

Even though cytology remains the gold standard to assess the nature of thyroid nodules, up to 30% of the results are indeterminate (BethesdaIII and IV). In these cases, current guidelines recommend performing diagnostic surgery, which proves malignancy in only 15-30% of cases. A more precise method is needed to avoid unnecessary surgeries, surgical complications and costs in the process of diagnosing indeterminate nodules. Complementary use of molecular profiling tests seems to help in this complex scenario...

Deep brain stimulation (DBS) of the anterior nucleus of the thalamus (ANT) is a promising treatment for patients with refractory epilepsy. However, therapy response varies and precise positioning of the DBS lead is potentially essential for maximizing therapeutic efficacy. We investigate if single-cell recordings acquired by microelectrode recordings can aid targeting of the ANT during surgery and hypothesize that the neuronal firing properties of the target region relate to clinical outcome. We prospectively included 10 refractory epilepsy patients and performed microelectrode recordings under general anesthesia to identify the change in neuronal signals when approaching and transecting the ANT...
