BACKGROUND AND OBJECTIVES Specially designed surgical instruments have been developed for single-incision laparoscopic surgery, but high instrument costs may impede the implementation of these procedures. The aim of this study was to compare the cost of operative implements used for elective cholecystectomy performed as conventional laparoscopic 4-port cholecystectomy or as single-incision lapa...

Objective: To evaluate the feasibility and safety of single-port laparoscopic hysterectomy comparing with multi-port laparoscopic hysterectomy in treatment of benign uterine diseases. Methods: Data were collected retrospectively by review of the medical records of 252 patients who underwent multi-port or single-port laparoscopic surgery for treatment of benign gynecologic diseases. Laparoscopy ...

PURPOSE In the early 1990's laparoscopic hernioplasty gained popularity worldwide. Thereafter, laparoscopic surgeons have attempted to improve cosmesis using single port surgery. This study aims to introduce and assess the safety and feasibility of single port laparoscopic total extraperitoneal (TEP) hernia repair with a nearly-scarless umbilical incision. METHODS Sixty three single port lapa...

BACKGROUND Surgical approaches such as transanal endoscopic microsurgery, which utilize small operative working spaces, and are necessarily single-port, are particularly demanding with standard instruments and have not been widely adopted. The aim of this study was to compare simultaneously surgical performance in single-port versus multiport approaches, and small versus large working spaces. ...

Some systems interact with their environment at physically distributed interfaces, called ports, and in testing such a system it is normal to place a tester at each port. Each tester observes only the events at its port and it is known that this limited observational power introduces additional controllability and observability problems into testing. Given a multi-port finite state machine (FSM...

BACKGROUND Thoracoscopic surgery is a commonly used endoscopic surgical treatment approach in patients with primary spontaneous pneumothorax. The conventional thoracoscopic approach utilizes three or more small wounds for surgery. Currently, a single port approach is a potential alternative procedure in general thoracoscopic surgery. We investigated whether a single-port approach is suitable as...

Single-port laparoscopy attempts to further reduce the surgical impact of minimally invasive surgery when compared to conventional laparoscopy [1–4]. Single-port laparoscopy might in general result in enhanced cosmetic outcomes and potentially reduced pain when compared to the conventional multi-port technique [5–8]. While manual single-port laparoscopy comes with certain technical limitations ...
