OBJECTIVE Robotic surgery systems were introduced recently with the objective of enhancing the dexterity and view during procedures that use a videoscope. The first case report of robot-assisted thoracoscopic removal of a benign neurogenic tumor in the thorax is presented. METHODS A 46-year-old woman presented with a history of paravertebral pain. A chest(More)
Laparoscopic surgery offers patients distinct benefits but is not without its disadvantages to surgeons in terms of maneuverability and visualization. Robotic telemanipulation systems were introduced with the objective of providing a solution to the problems in this field of surgery. The feasibility of robot-assisted surgery was assessed by performing 35(More)
BACKGROUND Robot-assisted surgical systems have been introduced to improve the outcome of minimally invasive surgery. These systems also have the potential to improve ergonomics for the surgeon during endoscopic surgery. This study aimed to compare the user's mental and physical comfort in performing standard laparoscopic and robot-assisted techniques.(More)
BACKGROUND For esophageal cancer patients, radical esophagolymphadenectomy is the cornerstone of multimodality treatment with curative intent. Transthoracic esophagectomy is the preferred surgical approach worldwide allowing for en-bloc resection of the tumor with the surrounding lymph nodes. However, the percentage of cardiopulmonary complications(More)
BACKGROUND In esophageal adenocarcinoma (EAC), concordance and prognostic significance of human epidermal growth factor 2 (HER-2) protein overexpression and gene amplification are equivocal, which led us to reevaluate this by immunohistochemistry (IHC) and in situ hybridization. METHODS One hundred and fifty-four patients were included in a tissue micro(More)
For gastric cancer patients, surgical resection with en-bloc lymphadenectomy is the cornerstone of curative treatment. Open gastrectomy has long been the preferred surgical approach worldwide. However, this procedure is associated with considerable morbidity. Several meta-analyses have shown an advantage in short-term outcomes of laparoscopic gastrectomy(More)
AIM The aim of this study was to determine the oncologic value of omentectomy in patients undergoing gastrectomy for gastric cancer. METHODS All consecutive patients with gastric cancer that underwent gastrectomy with curative intent between April 2012 and August 2015 were prospectively analyzed. The greater omentum was separately marked during operation(More)
BACKGROUND Individual variability in prognosis of esophageal cancer highlights the need for advances in personalized therapy. This systematic review aimed at elucidating the prognostic role of gene expression profiles and at identifying gene signatures to predict clinical outcome. METHODS A systematic search of the Medline, Embase and the Cochrane library(More)
