Single-port video-assisted thoracoscopic surgery (VATS) has been widely applied recently. However, there are still only few reports describing its use in mediastinum tumor resection. We present the technique of single-port video-assisted thoracoscopic mediastinum tumor resection and compare it with conventional VATS with regard to short-term outcome.We retrospectively enrolled 105 patients who ...

OBJECTIVE The aim of this paper was to demonstrate the techiniqes of single-port laparoscopic transperitoneal infrarenal paraaortic lymphadenectomy as part of surgical staging procedure in case of early ovarian cancer and high grade endometrial cancer. METHODS After left upper traction of rectosigmoid, a peritoneal incision was made caudad to inferior mesenteric artery. Rectosigmoid was mobil...

In an effort to further decrease patient postoperative scarring and discomfort, a new technique of microlaparoscopic assisted vaginal hysterectomy is employed. Using a 2-mm lateral port, a single infraumbilical port for the power source, and a 3-mm or 5-mm suprapubic port for aid in manipulation, seven consecutive patients underwent hysterectomy without complication and had rapid return to thei...

We developed a flexible port for NOTES which allows the use of conventional forceps for laparoscope-assisted surgery without change. The port is not affected by the location of the through hole in the gastrointestinal tract or vagina which elicits a problem in conventional NOTES, and its length can be adjusted during surgery by cutting the port itself. The port is made of polymer resin with a l...

In the neighbourhood gossiping problem, each node of a network starts with a unique message and must learn the messages of all of its neighbours. In this paper, we prove upper and lower bounds for neighbourhood gossiping in hypercubes under the single-port half-duplex and single-port full-duplex communication models.

in the late 1980's, the endoscopic revolution was launched and the world of surgery changed forever. Over the years, minimally invasive surgery, namely operative laparoscopy, has emerged as the standard treatment for many gynecologic benign and malignant etiologies. Laparoscopic surgery has answered the patient's right to better cosmesis, less blood loss, faster recovery, shorter hospital stay,...
