碩士 === 國立成功大學 === 醫學工程研究所 === 88 === Percutaneous Endoscopic Gastrostomy (P.E.G.) was researched and developed by Ponsky et al. in 1980. At the present time, it has not been much used in Taiwan, while it has been widespread in Europe and America. The reason why it has not been used widespreadly in Taiwan is due to the fact that medical insurance policy is not willing to cover it and the patients have to pay their own bill. So, if we can cut down the cost of the P.E.G. kit that ranges for 5,500 to 6,500 NT; then, P.E.G. should be used widespreadly by Taiwan patients. By the way, we can use a nasogastric tube and other substitute materials to construct a P.E.G. tube; then, the cost P.E.G. placement will be cheaper and widespread. The primary purpose of this study is to compare the serviceability of the lab-made P.E.G. tube with the commercial P.E.G. kit. Furthermore, this study was done in Lanyu Small Ear pigs in vivo with the two kinds of the tubes. Then we site the lab-made and commercial P.E.G. kits in the pig’s stomach by the Ponsky-Gauderer “pull” type, the most common method of operation. For certain days later, we took off the P.E.G. tube and recorded the pull force for removal. Secondly, we compare the serviceability of the lab-made P.E.G. tube with the different size of bolster both in vitro and in vivo. The results indicate as followings: (1) The serviceability of the lab-made P.E.G. tube is the same with commercial P.E.G. kit. During the five days, the pull force for removal decreases with the placement day, whether the lab-made or the commercial P.E.G. tubes. After five days later, the force doesn’t change too much. (2) As to the serviceability of the lab-made P.E.G. tube, there are significant differences between different size of bolster. (3) The main factor of the pull force for removal of the P.E.G. tube is the maturity of the fistula. With the immature fistula, the muscle of the abdominal wall will have stronger tension, then the P.E.G. tube is not easier to removal. The tube is easier to removal with the mature fistula, but there are no immediate complications.
