위암환자 전산화단층촬영시 경구조영제로서 물의 유용성에 관한 연구 : Usefulness of Water as an Oral Contrast Agent = Computed Tomography of Stomach Cancer

다국어 초록 (Multilingual Abstract)

Computed tomography is valuable for direct visualization of changes of gastric wall and staging of gastric tumor. Gastric distension is essential for the evaluation of gastric wall.
Computed tomography of the gastric wall after sequential ingestion of normal saline to 1000cc, followed by rapid intravenous injection of contrast medium, was performed in 36 patients with known gastric tumors. Three patients were excluded due to incomplete gastric distenstion and the lesion was not detected. Thirtythree patient was analysed preoperatively; the changes of wall were analysed in all patients and CT staging is compared with that of 19 cases who underwent surgery.
The results were as follows:
1. All cases are adenocarcinomas.
2. Thickening of gastric wall is detected in all cases and the ulceration within the thickened wall is detected only in five cases among the 25 cases of Borrmann type Ⅱ and Ⅲ.
3. Absence or presence of perigastric fat infiltration is correctly diagnosed in 15 cases among the 19 cases who underwent surgery
4. Lymph node metastasis, is correctly diagnosed in nine cases among the 19 cases
5. Pancreatic metastasis is correctly diagnosed in all cases who General acceptance and tolerance of water as a gastric contrast medium was good in all patients, and water made excellent negative contrast with gastric wall, and there was no side effects.
