이승열,남영수,김형묵,Lee, Seung-Yeol,Nam, Yeong-Su,Kim, Hyeong-Muk 대한흉부심장혈관외과학회 1995 Journal of Chest Surgery (J Chest Surg) Vol.28 No.1

Pectus excavatum occasionally occurs in patients who have underlying cardiac disease, especially Marfan syndrome. This report describes a patient with pectus excavatum who had ascending aortic aneurysm with aortic regurgitation and anterior leaflet prolapse of mitral valve. This patient underwent replacement of aortic valve and ascending aorta with 25 mm SJM valved conduit graft[Bentall operation with Cabrol shunt , and mitral valve replacement with SJM 31 mm, the pectus excavatum was corrected at the time of completion of the intracardiac operation with the modified sternal turnover. This procedure offered excellent operative exposure for the inracardiac operation with prevention of low cardiac output after operation due to depressed sternum and maintained chest wall stability resulting good cosmetic chest wall appearance. This patient recovered and discharged in good postoperative result with minimal temporary peroneal nerve palsy in his left leg.

흉강경을 이용한 양성 종격동 종양의 절제;2례 보고

이승열 대한흉부심장혈관외과학회 1992 Journal of Chest Surgery (J Chest Surg) Vol.25 No.7

Two cases of benign mediastinal tumor were treated by complete resection under the video-thoracoscopic guidance. The procedure has been performed on the 2 patients, allowing definite treatment and was less invasive than standard surgical treatment. The 2 patients have been benefited by decreased postoperative pain, reduced scarring of the skin and rapid recovery. Two patients had benign mediastinal tumors; teratodermoid on anterior mediastinum and neurilemmoma on posterior mediastinum. There were no operative death and complication, median hospital stay was four days.

이승열,이창호,김지현,정희영 한국원예학회 2012 Horticulture, Environment, and Biotechnology Vol.53 No.5

In this study, we distinguished Cucumber green mottle mosaic virus (CGMMV) infected seeds from healthy seeds using optical coherence tomography (OCT). Two dimensional OCT images and stereo micrographs revealed that the infected seeds had narrow gap between the seed coat and endosperm that were not present in the healthy seeds. Three dimensional OCT images confirmed that the narrow gaps were present in the inner structure of overall the infected seeds. A-scan analysis was also performed to calculate the distance from the seed coat to the endosperm. The results revealed a difference in the width of the gap of about 20 µm between healthy and infected cucumber seeds. Taken together, these results suggest that OCT could be applied as an effective non-destructive method for CGMMV infection of cucumber seeds.

이승열,예미지,백창기,최광식,강인규,이수헌,정희영 한국식물병리학회 2014 Plant Pathology Journal Vol.30 No.4

The incidence of Cherry necrotic rusty mottle virus(CNRMV) and Cherry green ring mottle virus (CGRMV)have recently been occurred in Korea, posing a problemfor sweet cherry cultivation. Since infected trees havesymptomless leaves or ring-like spots on the pericarp,it is difficult to identify a viral infection. In this study,the incidence of CNRMV and CGRMV in sweet cherryin Gyeongbuk province was surveyed using a newlydeveloped duplex reverse transcriptase polymerasechain reaction (RT-PCR) method that can detect bothviruses in a single reaction. CNRMV and CGRMVco-infection rates were 29.6%, 53.6%, and 17.6%,respectively, in samples collected from three differentsites (Daegu, Gyeongju and Gyeongsan) in Gyeongbukprovince during 2012 and 2013. This duplex RT-PCRmethod offers a simple, rapid, and effective way ofidentifying CNRMV and CGRMV simultaneously insweet cherry trees, which can aid in the management ofviral infections that could undermine yield.

이승열,김광택,최영호,김일현,백만종,선경,이인성,김형묵,Lee, Seung-Yeoll,Kim, Kwang-Taik,Choi, Young-Ho,Kim, Il-Hyun,Baik, Man-Jong,Sun, Kyung,Lee, In-Sung,Kim, Hyoung-Mook 대한흉부심장혈관외과학회 1999 Journal of Chest Surgery (J Chest Surg) Vol.32 No.9

배경: 식도암 절제 후 대치장기의 흉곽 내 경로는 환자의 상태, 암의 성상, 수술자의 기호나 경험 등에 따라 다양한 선택이 있다. 그 중 개흉술 후 피하 통로나 흉골하 통로를 이용하는 방법은 수술시간이 길며 술후 호흡기 합병증 등이 많이 발생한다는 보고가 있다. 본 연구는 대치장기의 흉곽 내 경로가 그러한 수술경과에 영향을 미치는지 확인하고자 계획되었다. 대상 및 방법: 식도암 절제 후 재건술을 시행 받은 131명의 환자 중, 대치장기의 경로가 후종격(I군, n=34), 흉골 하부(II군, n=31), 피하(III군, n=21)로 만들어 준 86명을 선택하여 각각의 조기 성적 및 합병증 등을 비교하였다. 결과: 남녀는 각각 79명 및 7명이었다. 암의 성상은 편평 상피암(squamous cell carcinoma)이 81명, 악성 선종(adenocarcinoma)이 5명이었다. 각 군의 수술 전 몸무게, 키, 나이, 식도암의 병기 및 위치, 전신상태 평가, 폐기능에서 차이가 없었다. 조기 성적에서 수술시간에는 유의한 차이 없었으나, 술후 인공호흡기 사용시간은 I군 (평균 20.6시간)에서 II군(7.8시간) 및 III군(3.4시간) 보다 유의하게 길었다(p=0.005). 중환자실 체류기간은 폐렴 등의 호흡기 합병증 때문에 III군(평균 6.4일)에서 I군(3.9일) 및 II군(3.1일) 보다 유의하게 길었으나(p=0.043), 술후 입원기간의 차이는 없었다. 술후 환자 일인당 수혈량은 I군에서 II군(1535mL), III군(1419mL) 보다 유의하게 많았으며(3833mL, p=0.04), 수혈을 받은 환자수도 II군(13/31명), III군(15/21명) 보다 I군에서 더 많았으나(30/34명, p=0.001) 출혈로인한 재수술 건수에는 차이가 없었다. 조기 사망률은 유의한 차이가 없었다. 조기 사망원인 중 패혈증은 I군에서 많았으나 문합부 유출과는 관계가 없었다. 그 외 조기 합병증과 후기 합병증, 평균 생존기간 등에서 각 군간에 유의한 차이는 없었다. 결론: 본 연구 결과는 후종격, 흉골 하부, 피하 경로간에 조기 성적이나 합병증 및 생존율에서 차이가 없음을 보여 주었다. 따라서, 식도암 절제 후 재건술에서 대치장기의 흉곽 내 통로 선정은 수술자의 기호와 경험이 수술 결과에 중요하다고 판단한다. Background: Selection of reconstruction route in esophageal cancer surgery is based on the patient's status, characteristics of tumor, surgeon's preference and experience. Of the various routes, it has been documented that subcutaneous or substernal route may prolong operation time and may be vulnerable to postoperative respiratory complications. This study was designed to evaluate whether the selection of reconstruction route affects the surgical outcomes. Material and Method: Of 131 patients who have undergone resection and reconstruction for esophageal cancer, posterior mediastinal route(Group I, n=34), substernal route (Group II, n=31), and subcutaneous route(Group III, n=21) were retrospectively reviewed in 86 patients. Results of early operations and morbidities were compared between the groups. Result: There was a male prevalence(79 of males vs. 7 of females). There were 81 squamous cell cancers and 5 adenocarcinomas. There were no differences between groups in weight, height, age, cancer staging and location, and in the preoperative anesthetic risk evaluation and pulmonary function test(p=NS). Postoperative mechanical ventilation time was longer in Group I(20.6 hours) than in Group II(7.8 hours) or III(3.4 hours)(p=0.005). Duration of stay in the intensive care unit was prolonged in Group III(6.4 days) compared to Group I (3.9 days) or II(3.1 days)(p=0.043). No differences were noted in the duration of hospital stay between the groups(p=NS). Blood transfusion was needed in 30 out of 34 patients in Group I compared to 14/31 in Group II or 15/21 in Group III(p=0.001). The mean amount of transfusion for each patient was also higher in Group I(3,833 mL) than in Group II(1535 mL) or Group III(1419 mL)(p=0.04), but there was no difference in the inreoperation due to bleeding. Ea ly mortality rate was substantially higher in Group I(17.6%) but the differences between the groups were insignificant(p=NS). Although sepsis was a more prevalent cause of death in Group I, it was not related to anastomotic leak. Other morbidities did not differ between the groups(p=NS). Conclusion: In above results show that the reconstruction route does not affect the outcome of esophageal cancer surgery. We believe that the selection of reconstruction route can be based on the surgeon's preference and experience.
