Three-port versus four-port laparoscopic cholecystectomy.
BACKGROUND/AIMS Since the first successful laparoscopic cholecystectomy with the establishment of pneumoperitoneum in France by Mouret in 1987, it has become the golden standard for cholecystectomy. Generally techniques with four trocars have been used with surgeons but some of them prefer 3-trocar techniques. Our aim is to compare the clinical outcomes of three- and four-port techniques prospe...
متن کاملThree Port Versus Standard Four Port Laparoscopic Cholecystectomy- A Prospective Study
The first laparoscopic cholecystectomy (LC) was performed in 1987 by Philip Mouret and later established by Dubois, Perissat, Reddick, and others in 1990's (1-3). Since then, there have been many changes and improvements in the technique. Traditional LC is performed using 4 port technique. The fourth (lateral) trocar is used to grasp the fundus of the gall bladder so as to expose the Calot's tr...
متن کاملA Modified Three-Port Laparoscopic Cholecystectomy: Shifting the Third Port to the Umbilicus
Aim: The aim is to shift the 5 mm port from the right upper abdomen to the umbilicus in threeport laparoscopic cholecystectomy to obtain better cosmetic results. Methods: The three ports in conventional three-port laparoscopic cholecystectomy were placed in a 10 mm epigastric incision, a 5 mm umbilical incision and a 5 mm right upper abdominal incision. Our modified method involved movement of ...
متن کاملDemonstration of three-port grating phase relations.
We experimentally demonstrate the phase relations of three-port gratings by investigating three-port coupled Fabry-Perot cavities. Two different gratings that have the same first-order diffraction efficiency but differ substantially in their second-order diffraction efficiency have been designed and manufactured. Using the gratings as couplers to Fabry-Perot cavities, we could validate the resu...
متن کاملHybrid Energy System using Three Port Converter
Three Port Converters are used for merging more than a single source in order to improve the power handling capability. Here the first two ports acts as the sources and the third port acts as the output or to the Load. The objective is combining the Wind Energy Systems with the Existing Three Port Converter System instead of a Battery Storage. The proposed system is simulated and verified using...
