Pancreatic pseudocyst is a well recognized complication of acute or chronic pancreatitis. Active treatment (surgical or endoscopic) has been recommended if the pseudocyst persists for more than 6 weeks after the diagnosis. Open trans-abdominal drainage was initially the mainstay treatment for it. However, over the past decade, laparoscopic techniques have been developed to provide patient with minimal access alternative. We report a case of a large symptomatic pseudocyst which developed following attack of severe gallstone pancreatitis. Laparoscopic cholecystectomy and cysto-gastrostomy were done at the same sitting. The operative technique is briefly explained.
This paper presents the development of a PC-based microwave five-port reflectometer for the determination of moisture content in oil palm fruits. The reflectometer was designed to measure both the magnitude and phase of the reflection coefficient of any passive microwave device. The stand-alone reflectometer consists of a PC, a microwave source, diode detectors and an analog to digital converter. All the measurement and data acquisition were done using Agilent VEE graphical programming software. The relectometer can be used with any reflection based microwave sensor. In this work, the application of the reflectometer as a useful instrument to determine the moisture content in oil palm fruits using monopole and coaxial sensors was demonstrated. Calibration equations between reflection coefficients and moisture content have been established for both sensors. The equation based on phase measurement of monopole sensor was found to be accurate within 5% in predicting moisture content in the fruits when compared to the conventional oven drying method.
