BACKGROUND Interplay between the components of a lipoplasty system (suction pump, suction tubing, collection canister, and cannula) determines liposuction efficiency. However, in clinical practice, none of the components are more important than the cannula. Cannula design including port design, port placement, and shaft characteristics is the single most influential contributor to flow resistan...

This study set out to establish that land transport system in the country of destination, determines the turn-around time, capacity utilisation of port infrastructure, facilities and cargo-handling equipment and general port performance. Of particular interest, is the contribution of road transport infrastructures and system to the magnitude of turn-around time, port performance and general eco...

BACKGROUND/AIMS To decrease surgical trauma and scar formation we present intracorporeal two-port procedure in selected patients. METHODOLOGY Supraumbilical 5mm port is used for the laparoscope. Suprapubic 12mm port is in the midline or left paramedian position below the underpants line. Pretied loop suture is tied around the base, 1-2 cm distally from the origin of the appendix, or below the...

OBJECTIVES To investigate effects of the limited two-port video assisted thoracic surgery on treatment of spontaneous pneumothorax. METHODS A retrospective analysis of 96 patients with spontaneous pneumothorax who underwent video assisted thoracic surgery was conducted in the present study, in which 23 cases underwent the limited two-port video assisted thoracic surgery while 73 cases treated...

The Communications-based train control(CBTC) system has gradually become the first choice for signal systems of urban mass transit. However, how to guarantee its safety has become a research hotspot in safety fields. The generic test system with high efficiency has become the main means to verify the function and performance of CBTC system. This paper discusses a composable modeling method for ...

Port-a-cath is a widely used device in patients with long-term venous access demand such as frequent or continuous administration of medications such as Enzyme Replacement Therapy (ERT), chemotherapy delivery, blood transfusions, blood products, and fluids. Patients with Lysosomal Storage Diseases (LSDs) often require recurrent courses of ERT. We reviewed our experience of using port-a-caths in...

BACKGROUND Different complications may occur at laparoscopic port sites. The incidence of these varies with the size of the ports and the types of procedure performed through them. OBJECTIVES The aim was to observe the rate and types of complications attending laparoscopic port wounds and to identify risk factors for their occurrence. PATIENTS AND METHODS This is a prospective descriptive s...

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...

INTRODUCTION Transanal endoscopic microsurgery (TEM) is widely used for the excision of both benign and malignant rectal tumours. It is relatively expensive and can be a challenging technique. A recent development in laparoscopic surgery is the single-port technique (single-incision laparoscopic surgery, SILS). The SILS port is a flexible multichannel port for transumbilical laparoscopic surger...

BACKGROUND The PAS-Port (Cardica Inc, Redwood City, CA) is an automated system that allows for the clampless anastomosis of vein grafts to the aorta. The intent of this study was to prospectively compare one year graft patency of this system with conventional hand-sewn anastomoses in a prospective, randomized trial. METHODS A total of 99 patients undergoing elective off-pump coronary bypass s...
