복수를 가진 8명의 간경화증 환자 및 Tenckhoff 카테타의 복강내 이식을 받은 한명 의 만성 신부전증환자에 발생한 호흡곤란을 유발한 수흉이 복수의 횡격막을 통한 이동에 의 한 것임을 확인하기 위하여 복강내에 $^{99m}Tc-tin$ colloid를 주입한 후에 복부와 흉부의 동위 원소 주사상을 얻었는바 모든 환자에서 3분내지 30분후에 흉부에 동위원소의 활동상이 나타 나기 시작하여 지속적으로 그강도가 증가하였다. 따라서 비염증성 복수가 있는 환자들에서 수흉이 발생한 경우 그 원인 규병에 있어 동위원소 주사법이 일차적으로 이용될수 있는 것 으로 생각된다.

수술중 방사선조사가 소양물합의 치료에 미치는 영향에 관한 실험적 연구
서흥석 대한영상의학회 1983 대한영상의학회지 Vol.19 No.1
To evaluate the influence of intraoperative irradiation on the healing of jejunal annastomosis, an experimental study was undertaken using a total of 150 rats. The bursting pressure of the normal jejunum was obtained in gropu I. Group II was subjected to resection and anastomosis, and group III was irradiated on the anastomosed jejunum with a single dose of 1,000 rads. Healing process was evaluated by measuring bursting pressure of the anastomosed jejunum on each postoperative day from 2nd to 14th, and on 21th day. Bursting pressure was tested by inflating the loop of gut with water, and bursting sites were observed. The results obtained are summarized as follows : 1. The bursting pressure of the anastomosed jejunum retained normal strength by the 7th postoperative day in the nonirradiated group, whereas by the 11th postoperative day in the irradiated group. 2. Irradiation caused delay in the healing of anastomosis of the jejunum until the 10th postoperative day ; but after then there was no significant difference in bursting pressure between both groups. 3. In the jejunal segments with subnormal strength, bursting occurred exclusively at the non-anastomotic site in both groups; Bursting started along the mesenteric border in the non-irradiated group, whereas rupture usually occurred on the antimesenteric border in the irradiated group. In the jejunal segments with subnormal strength, bursting usually started on the mesenteric border of the anastomotic site in both groups. The results indicate that intraoperative irradiation with a single dose of 1,000 rads causes no harmful effect on the healing of anastomosis of the jejunum in rats. Therefore, this study suggests the possibility of more effective clinical application of intraoperative irradiation.

문맥압항진중에 동반된 비장기능항진증에 대한 부분적 비동맥색전술
서흥석 대한영상의학회 1990 대한영상의학회지 Vol.26 No.2
Partial splenic embolization (PSE) was performed in thirteen cirrhotics and two patients of idiopathic portal hypertension with hypersplenism using Gelfoam pieces suspended in an antibiotic solution. The patients were followed for 60 weeks after PSE, and decreased gradually but maintained within normal limit until 60 weeks after PSE. Platelet count increased immediately and normalized at the first week, and reached at the maximal value at the 4th week after PSE. And then platelet count decreased gradually but maintained within normal limit until 60 week after PSE. Hemoglobin value tended to increase gradually about 4 weeks after PSE without significant interval change initially. After PSE abdominal pain, fever, ascites and pleural effusion were observed ut were well tolerated, and there were no serious complications such as splenin abscess, subphrenic abscess, splenic rupture and so on. Consequently, PSE is thought to be an attractive therapeutic modality to physicians managi g patients with hypersplenism in portal hypertension not only because it is a nonsurgical procedure without serious complications but because it provides excellent results hematologically.
