Endoscopic Management of Malignant Colonic Obstruction

서승영,Sang Wook Kim 대한소화기내시경학회 2020 Clinical Endoscopy Vol.53 No.1

Advanced colorectal cancer can cause acute colonic obstruction, which is a life-threatening condition that requires emergency boweldecompression. Malignant colonic obstruction has traditionally been treated using emergency surgery, including primary resectionor stoma formation. However, relatively high rates of complications, such as anastomosis site leakage, have been considered asmajor concerns for emergency surgery. Endoscopic management of malignant colonic obstruction using a self-expandable metalstent (SEMS) was introduced 20 years ago and it has been used as a first-line palliative treatment. However, endoscopic treatment ofmalignant colonic obstruction using SEMSs as a bridge to surgery remains controversial owing to short-term complications and longtermoncological outcomes. In this review, the current status of and recommendations for endoscopic management using SEMSs formalignant colonic obstruction will be discussed.

Differentiated thyroid cancer(DTC) carry a favorable prognosis but a few patients present with aggressiveness. Prognostic indicators of recurrence and of death are age at diagnosis, histologic type, and extent of the tumor. The overall 10-year survival rates of differentiated thyroid cancer are about 80-95% but overall survival after the discovery of distant metastasis is about 40% at 10 years. We report 4 cases that have shown poor prognosis, due to distant metastasis, cancer progression and refractory relapse of cancer despite of appropriate management. Although DTC has shown good prognosis generally, a few patients present very poor prognosis. Thus DTC patients need to be closely monitored despite of their good prognosis.

Background/Aims: With recent changes in the treatment of pancreatic cancer, patients’ active decision-making has become more important. Nevertheless, it is difficult to give patients proper insights into the disease. The purpose of this study was to determine associated factors between pancreatic cancer awareness and treatment decisions as well as how cancer awareness affects the timing of treatment decisions and the desired treatment method. Methods: This is a retrospective study that reviewed and analyzed the electronic medical records of 110 patients who were diagnosed with pancreatic cancer from January 2013 to April 2016. A "patient with pancreatic cancer awareness" means that the patient was informed of their disease state before making the first treatment decision. Results: Of all, only 63.6% of patients (n=70) were shown to have pancreatic cancer awareness before making their first treatment decision. Compared to patients without pancreatic cancer awareness, patients with pancreatic cancer awareness were younger (65.00 vs. 76.98, t=6.70, p<0.001), were more likely to have presented their spouse as legal guardians (42.9% vs. 10.0%, χ2=31.70, p<0.001), and spent a shorter time for treatment decision-making (1.6 vs. 10.5 days, t=4.26, p<0.001). The patients without pancreatic cancer awareness were more likely to opt for best supportive care compared to the patients with pancreatic cancer awareness (79.5% vs. 28.6%, χ2=31.70, p<0.001). Conclusions: This study provides insights into cancer awareness. Since cancer awareness appears to influence treatment decision, it is necessary to develop guidelines to improve cancer awareness of patients.

기계경비시스템의 기술 변화추세와 개발전망

정태황,서승영 한국경호경비학회 2009 시큐리티연구 Vol.- No.19

기계경비시스템은 대부분 전자·정보·통신 기기로 구성되어 있기 때문에 정보통신환경의 변화는 기계경비시스템의 기술, 운영체계, 운영방법 등에 영향을 미치게 된다. 본 연구는 기계경비시스템의 기술개발 동향 및 실태를 분석하고 기술개발 전망을 제시하는데 있다. 본 연구는 문헌연구와 기계경비시스템을 사용하는 수요자와 공급자와의 면담을 통한 분석과, 기술개발업자와 시스템 설치 기술자를 대상으로 한 설문조사를 통해 분석결과에 대한 검증을 실시하였다. 국제적으로 경쟁력이 있는 DVR 기술은 본래의 기능인 영상녹화 기능을 위주로 Motion Detection 기능과 상황변화 인식 기능, 목표물 추적 기능 등과 같은 다양한 기능을 수행할 수 있는 하이브리드 DVR 기술개발 쪽으로 진행될 것이며, 상황변화를 인식할 수 있는 기술은 현장에 설치된 많은 카메라를 소수의 인원이 효과적으로 감시할 수 있게 하여 기존의 CCTV시스템의 기능을 보다 향상시킬 수 있을 것이다. 그리고 영상전송기능을 수행하는 인터넷 서버 기술과 영상인식 소프트웨어가 카메라에 내장된 ‘Embedded IP카메라’ 기술개발은 CCTV시스템의 구성체계를 보다 간소화 시킬 수 있을 것이다.생체인식 중 지문인식기술과 얼굴인식기술은 국제적인 경쟁력을 가지고 기술개발이 진행되지만 얼굴인식기술은 인식기술에 있어서는 선진국과 비슷한 수준인 것으로 평가되고 있으나 인식거리를 확보하는 기술과 감시 기능, 3D인식 기술부분에 있어 다소 신뢰성이 떨어져 이를 보완하기 위한 지속적인 개발이 이루어질 것이다. RFID의 무선인식과 추적기능은 사람 또는 차량의 출입통제나 물품의 반입․반출의 감시․통제 등을 위해 유용하게 적용될 것으로 평가되고 있어 RFID의 하드웨어와 소프트웨어 기술개발이 활발하게 진행될 것으로 전망되지만 시장여건과 새로운 제품 도입을 꺼리고 수입 의존도가 높은 현상을 개선하기 위하여 개발된 제품을 사용할 수 있는 여건 조성 등 기술개발을 촉진하기 위한 적극적인 지원이 필요한 것으로 분석된다.행동패턴을 인식하여 침입상황을 감지하는 센서기술은 기존의 오작동이 많은 공간감지 센서를 대신하여 경보신호의 신뢰도를 향상시켜 자신있는 현장대응을 가능하게 해줄 수 있는 기술로 적극적으로 개발이 이루어질 것으로 전망된다. 행동패턴인식기술과 영상변화를 탐지하고 분석하는 영상인식기술은 유사한 기술로 서로 연계될 수 있으며, 경보신호전송 기술, 영상추적기술, RFID의 무선인식 및 추적 기술, 그리고 이를 관리하기 위한 미들웨어 기술을 통합하여 이상상황에 보다 효과적으로 대응할 수 있는 통합관제시스템을 구축할 수 있을 것이다. Electronic security system is composed mainly of electronic-information- communication device, so system technology, configuration and management of the electronic security system could be affected by the change of information- communication environment. This study is to propose the future prospect on the development of technique for electronic security system through the analysis of the trend and the actual condition on the development of technique. This study is based on literature study and interview with user and provider of electronic security system, also survey was carried out by system provider and members of security integration company to come up with more practical result.Hybrid DVR technology that has multi-function such as motion detection, target tracking and image identification is expected to be developed. And 'Embedded IP camera' technology that internet server and image identification software are built in. Those technologies could change the configuration and management of CCTV system.Fingerprint identification technology and face identification technology are continually developed to get more reliability, but continual development of surveillance and three-dimension identification technology for more efficient face identification system is needed.As radio identification and tracking function of RFID is appreciated as very useful for access control system, hardware and software of RFID technology is expected to be developed, but government’s support for market revitalization is necessary. Behavior pattern identification sensor technology is expected to be developed and could replace passive infrared sensor that cause system error, giving security guard firm confidence for response. The principle of behavior pattern identification is similar to image identification, so those two technology could be integrated with tracking technology and radio identification technology of RFID for total monitoring system. For more efficient electronic security system, middle-ware's role is very important to integrate the technology of electronic security system, this could make possible of installing the integrated security system.

위염 분류의 역사적 배경

임성균,서승영 대한상부위장관ㆍ헬리코박터학회 2023 Korean Journal of Helicobacter Upper Gastrointesti Vol.23 No.2

Gastritis is common worldwide. The combination of Helicobacter pylori (H. pylori) infection with background gastritis, including atrophic gastritis or intestinal metaplasia is implicated as an important etiopathogenetic contributor to gastric cancer. Since the gastritis classification proposed by Schindler, research has focused on classification of gastritis for accurate diagnosis and prediction of prognosis. Advances in endoscopic technology have enabled more accurate visualization of the gastric mucosa and ‘targeted’ biopsies with the emergence of newer classifications based on visual findings (Kimura-Takemoto classification) and more specific histopathological findings using targeted biopsies (Whitehead classification). Following the discovery of H. pylori, it is mandatory to consider its role as an important contributor to gastritis. Therefore, it was necessary to redefine the classification of gastritis and arrive at a consensus, which led to the establishment of an international consensus classification, referred to as the Sydney system. However, the Sydney system alone cannot predict the gastric cancer risk, and scoring systems such as the Operative Link for Gastritis Assessment and the Operative Link on Gastritis Assessment based on Intestinal Metaplasia were proposed. These systems are based on histopathological findings observed in endoscopic biopsy specimens. However, availability of high-definition images following technological advances has facilitated the emergence of a visual classification, the Kyoto classification. In contrast to the Sydney system, the Kyoto classification is based exclusively on interpretation of visual findings and focuses on detection of H. pylori infection and gastric cancer prediction. In this review, we summarize the history and background of the various classifications of gastritis.

Feasibility of Adopting the "Step-up Approach" in Managing Necrotizing Pancreatitis-induced Pancreatic-colonic Fistula

임성균,김성훈,서승영,양희찬,이승옥 대한소화기학회 2019 대한소화기학회지 Vol.73 No.6

Managing acute pancreatitis is clinically challenging because of the generally poor patient condition, the variety of treatment options depending on the severity and complications, and the uncertainty of outcomes. Recently, the step-up approach, which involves less invasive initial treatment and more invasive subsequent treatment, where necessary, has been proposed as the mainstay of managing pancreatitis. This paper presents a case of a 57-year-old man with severe acute pancreatitis, who developed an unexpected fistula in the rectum, which was treated successfully using the step-up approach. In managing this case, the authors faced clinical challenges in determining the infection of necrotic tissue in the early phase of the disease, the optimal timing and method of drainage, and the fistula closure or repair technique. Successful management of this case using the step-up approach validated current recommendations and suggests that it is a reasonable treatment strategy for pancreatic-colonic fistulas. This case also highlights the importance of an awareness that pancreatitis-associated complications can develop in an unexpected manner.
