For multiport image-guided minimally invasive surgery at the lateral skull base a quality management is necessary to avoid the damage of closely spaced critical neurovascular structures. So far there is no standardized method applicable independently from the surgery. Therefore, we adapt a quality management method, the quality gates (QG), which is well established in, for example, the automoti...

INTRODUCTION Single incision transumbilical laparoscopic procedures are the next step in development of minimally invasive surgery. Recent studies prove that the new technique can be a safe alternative to multiport laparoscopy; therefore it is becoming more and more popular. AIM We present our preliminary experience with single incision laparoscopy of the spleen. MATERIAL AND METHODS We ana...

OBJECTIVE Multiport laparoscopic surgery in colon pathology has been demonstrated as a safe and effective technique. Interest in reducing aggressiveness has led to other procedures being described, such as SILS. The aim of this meta-analysis is to evaluate feasibility and security of SILS technique in colonic surgery. MATERIAL AND METHODS A meta-analysis of twenty 7 observational studies and ...

BACKGROUND We assessed the potential impact of infusion tubing on blood glucose imbalance in ICU patients given intensive insulin therapy (IIT). We compared the incidence of blood glucose imbalance in patients equipped, in a nonrandomized fashion, with either conventional tubing or with a multiport infusion device. METHODS We retrospectively analyzed the nursing files of 35 patients given IIT...

INTRODUCTION Nowadays the vast majority of inguinal hernia repairs are laparoscopically assisted. Single incision laparoscopy aims to accelerate recovery and provide a better cosmetic outcome after the operation. AIM To present our own modification of the totally extraperitoneal (TEP) procedure with a single incision and without a multiport, and compare the results with those obtained in the ...

In the present paper the pressure drop characteristics of a 1.4 mm hydraulic diameter multiport minichannel tube during adiabatic two-phase flow of HFC refrigerants are discussed. The tube consists of eleven parallel rectangular cross section channels. Although much experimental research has been devoted to investigate the pressure drop characteristics of R134a inside multiport minichannels in ...

AIM Single-incision laparoscopy for colorectal surgery is of growing importance. The experience of colorectal resection through single-incision laparoscopic surgery was assessed, including the patient outcomes. METHOD A meta-analysis was performed of studies comparing single-incision laparoscopic with multiport laparoscopy. Endpoints included conversion to laparotomy, operation time, postoper...

Laparoscopic ovariohysterectomy using single-portal access was performed in nine selected owned dogs admitted for elective ovariohysterectomy and the surgical technique and outcomes were detailed. A multiport device (SILS Port, Covidien, USA) was placed at the umbilical area through a single 3 cm incision. Three cannulae were introduced in the multiport device through the access channels and la...

Compact and efficient power converter solutions are seen to be the backbone of future transportation systems in order cope with ongoing transition towards greener systems. Such usually comprise a main load section, which one or more propulsion traction motors connected, addition an auxiliary load, might hotels air conditioning for example. This can as low 5-10% power. Therefore, it chall...
