초록

본 연구에서는 식도 재건 수실 시 유문 성형 여부와 위장 이식편을 이용한 식도 접합 경로에 따른 음식물 역류 현상에 대해 고찰하였다. 위장 이식편의 두 가지 접합 경로(전방, 후방)는 환자 10 명의 CT 영상으로부터 얻어졌으며, 식도관 모델은 RP 로 제작하였다. 식도관은 유문 성형 여부의 두 가지 유문 모델에 연결하였고, 다양한 압력과 펄스폭을 적용하여 역류되는 유체의 체적과 최대 역류 높이를 측정하였다. 그 결과, 역류 체적과 높이는 압력에 따라 증가하였으며, 유문 성형을 하면 전방 경로가 후방 경로보다 역류되는 체적과 높이 작게 나타났다. 역류량은 펄스폭이 증가하면 증가하나 최대 역류높이에 대한 영향은 유문 성형 여부에 따라 달라진다.

In this study, duodenogastric reflux has been investigated according to pyloroplasty and the path of the gastric tube in esophageal reconstruction. The paths of the gastric graft (front and rear paths) were determined from the CT images of ten patients, and the gastric tube model was constructed using an RP technique. The gastric tubes were connected to the pylorus models with and without pyloroplasty. Various distal pressures and pulse widths were applied, and the volume and maximum height of the refluxate were measured. The results show that the volume and height of the refluxate increase with the distal pressure, and the front path leads to a smaller volume and lesser height of the refluxate than the rear path if pyloroplasty is conduced. The volume of the refluxate is markedly increased by a larger pulse width, but its effect on the maximum height depends on whether pyloroplasty is conducted.
