본 연구는 2010년 3월부터 2011년 9월까지 뇌동맥류로 H병원에 내원한 환자 중 혈관조영술을 시행하여 코일 색전술을 받은 53명의 환자를 대상으로 뇌동맥류의 체적에 따른 코일의 길이 특성을 평가하였다. 뇌동맥류에 대한 색전술을 시행한 환자의 뇌동맥류에 대하여 볼륨렌더링기법으로 체적을 구하였으며, 코일색전술을 실시한 후 코일의 체적 및 길이를 구하여 체적율을 계산하였다. 뇌동맥류의 크기에 따른 색전체적율은 6㎜ 이하에서는 43.11±3.11%, 6~10㎜에서는 36.07±2.03%, 10~15㎜ 이상은 40.91%, 20㎜ 이상에서는 38.25%를 나타내어 권고된 체적율과 유사한 수치를 나타내었다. 뇌동맥류의 형태에 구분 없이 체적에 따른 코일 길이는 직경 0.25㎜인 한 가지 코일을 사용한 경우 20~100㎣의 1㎣ 당 0.65㎝로 조사되었다. saccular type의 aneurysm volume에 사용한 경우 20~150㎣의 1㎣ 당 0.62㎝, multi lobulated type의 aneurysm volume에 사용한 경우 20~90㎣의 1㎣ 당 0.60㎝로 조사되었다. This study presents the assessment results of coil length characteristics according to the volume of cerebral artery among the inpatients that received angiography and coil embolization following intracranial aneurysm from March, 2010 to September 2011. The volume rendering method was applied to the patients that received embolization to their cerebral arteries to obtain volume measurements. After coil embolization, the volume ratios were calculated with the volumes and lengths of coils. The embolic volume ratios were 43.11±3.11%, 36.07±2.03%, 40.91%, and 38.25% when the aneurysm sizes were 6㎜ or less, 6~10㎜, 10~15㎜ and 20㎜ or more, respectively, being similar to the recommended volume ratios. Regardless of the types of aneurysm, the coil length according to volume was 0.65㎝ per 1㎣ of 20~100㎣ when one type of 0.25㎜ diameter coil was used. They were 0.62㎝ per 1㎣ of 20~150㎣ when one type of coil was used in the aneurysm volume of the saccular type and 0.60㎝ per 1㎣ of 20~90㎣ when one type of coil was used in the aneurysm volume of the multi-lobulated type.

N/A Aspiration pneumonia, a recognized complication of enteral feeding via a nasogastric tube, is considered uncommon with percutaneously placed gastrostorny tube feeding. But the specific influ- ence of PEG on the LES has not been studied well. To evaluate PEG effects on the LES in long-term period, we conducted a prospective study in 10 neurologically compromised patients. The mean LES pressure was 21.6 (+2.4) mmHg before PEG: 22.0 (+3.4) mmHg at 10 days and 1:3.8 (+2.6) mmHg at 6 months post-PEG. Following PEG, either the location of pressure inversion point or the length of LES remained unchanged. This study suggests that PEG does not affect the LES pressure in short- term period, but reduces it in long-term follow-up period. The observed decrease in LES pressure after PEG may be explained mechanically, based upon the intraluminal pressure changes accounted for by the law of Laplace. The PEG exerts the gastric fixation to the abdominal wall. This, in turn, tends to widen the diameter of the LES, leading to a drop in intraluminal pressure.

We performed the percutaneous endoscopic gastrostomy in 7 patients who were unable to swallow. Feeding via with the PEG was carried out in a bolus fashion requiring no additional equipment. In our experience no aspiration occurred and only one case of skin care problem arose. The PEG appeared to be safe and effective means of nonvolitional feeding in the home, hospital or in an extended care facility.

A prospective esophageal manometry using the high-fidelity recording equipment was performed in 35 healthy Korean. The manometric data of this study showed: 1) 3.4(+-0.67)cm for LES length; 19.8(+-7.05)mmHg for LES pressure; 7.43(+-2.21) sec. For the relaxation time of LES; 21.9(+-2.7)cm for the length of esophageal body; 28.3(+-13)~ 55.7(+-11)mmHg for the amplitude of esophageal contractions; 3.2(+-0.6)~3.8(+-1.0)sec. For the duration of the contraction waves; 3.1(+-1.2)~6.6(+-2.3)cm/sec. For the velocity of the contraction waves; 2.6(+-0.9)cm for UES length; 0.95(+-0.3)sec. For the relaxation time of UES, 2) Radial pressure asymmetry of the LES was observed. The highest pressure occurred in the posterior direction and the lowest pressure in the right direction. 3) Abnormal esophageal responses to swallowing including aperistalsis, breaking waves, simultaneous contraction, spontaneous contraction, double peaked contraction and repetitive contraction were observed rarely in healthy subjects.

Nutritional assessment is a rational prerequisite to the provision of adequate patient care. Anthropometric measurement is relatively simple but valuable method of nutritional assessment and current)y widely used in clinical practice. But Korean anthropomeric data were not yet obtained. To obtain anthropometric data in Korean, we measured body weight, height, triceps skin- fold thickness (TSF), and midarm circumference (MAC) of 2021 Korean aged from 16 to 9S years. The midarm fat area (MAFA) and midarm muscle area (MAMA), based on the measurement of TSF and MAC, were calculated. The results were summarized as follows; 1) The mean value of body weight of Korean, under 65 years old was 65.6(±8.3)kg in male, 54.2(±6.9)kg in female; over 65 years old 58.8(±9.5)kg in male, 48.8(±9.4)kg in female. 2) The mean value of the height of Korean, under 65 years old was 169.0(±5.6)cm in male, 157.7(±4.7)cm in female; over 65 years old 166.1(±5.1)cm in male, 148.0(±6.8)cm in female. 3) The mean value of MAC of Korean, under 65 years old was 27.5(±2.7)cm in male, 26.6(±3.0)em in female; over 65 years old 25.4(±2.7)cm in male, 24.5(±3.6)cm in female. 4) The mean value of TSF of Korean, under 65 years old was 12.2(±5.7)mm in male, 20.6(±7.1)mm in female; over 65 years old 11.4(±5.4)mm in male, 16.1(±6.8)mm in female, 5) The mean value of MAMA of Korean, under 65 years old was 45.2(±10.2)cm² in male, 32.8(±9.1)cm² in female; over 65 years old 38.3(±7.4)cm² in male, 30.6(±7.8)cm² in female. 6) The mean value of MAFA of Korean, under 65 years old was 15.6(±7.3)cm² in male, 24.2(±9.2)cm² in female; over 65 years old 13.7(±7.4)cm² in male, 18.1(±9.2)cm² in female. This study shows that anthropometric data of Korean are considerably lower than those published in western country. These results suggest racial difference. So nutritional assessment in Korean should be done by reference chart from Korean.
