The gastric cancer takes the great part of the cancer occurrence and the mortality from cancer in Korea, and the early detection of gastric cancer is very important in the treatment and convalescence. This paper. for the early detection of gastric cancer, Proposes the analysis system of endoscopic image of the stomach that detects the abnormal region by using the change of color in the image and provides the surface tissue information to the detector. While the advanced inflammation and the cancer may be easily detected, the early inflammation and the cancer have a difficulty in detection and require the more attention lot detection. This paper, at first, converts the endoscopic image to the Image of IHb(Index of Hemoglobin) model and removes noises incurred by illumination, and next, automatically detects the regions suspected as cancer and provides the related information to the detector, or provides the surface tissue information for the regions appointed by the detector. This paper does not intend to provide the final diagnosis of the detected abnormal regions as gastric cancer, but provides the supplementary mean that reduces the load and mistaken diagnosis of the detector by automatically detecting the abnormal regions being not easily detected by human eyes and providing the additional information for the diagnosis. The experiments using practical endoscopic images for performance evaluation showed that the proposed system is effective in the analysis of endoscopic image of the stomach.

Brodie abscess is a localized form of subacute or chronic osteomyelitis which is common in children but may also occur in adulthood. When Brodie abscess is located in the posterior metaphysis of the proximal tibia, open biopsy and curettage have a difficulty in approach to the lesion and can cause neurovascular injury or soft tissue contamination. We report a case wherein a novel surgical technique was used to treat a Brodie abscess in the posterior proximal tibial metaphysis in 48 year-old-male with endoscopic-assisted curettage by commercial anterior cruciate ligament targeting device(Rigid Fix; Mitek, Johnson & Johnson, Norwood, MA). Two portals were created toward the abscess site and, through each portal interchangeably, the granulation tissue and sclerotic bone could be excised. We believe that endoscopic-assisted curettage presents safe technique, decreased morbidity, accurate assessment of the extent of the abscess and possible improvement in long-term outcomes.

Background: Endobronchial tuberculosis is one of the serious complications of pulmonary tuberculosis. Without early diagnosis and proper treatment of endobronchial tuberculosis, bronchostenosis can leave and lead to the collapse of distal lung parenchyme, bronchiectasis, and secondary pneumonia accompanied with moderate to severe dyspnea, cough, hemoptysis, and localized wheezing. Therefore steroid therapy has been tried to prevent bronchostenosis. But the effect of steroid therapy on the endobronchial tuberculosis is not definite at present. We tried to elucidate the effect of steroid on the treatment of endobronchial tuberculosis for prevention of bronchostenosis. Methods: We observed the initial and sequential bronchoscopic findings, pulmonary function tests and simple chest roentgenograms in 58 patients diagnosed as endobronchial tuberculosis and admitted to Chung-Ang university hospital from 1988 to 1992. The patients in nonsteroid group (n=39) were treated with anti-tuberculosis chemotherapy only and steroid group(n=17) with combined steroid therapy. Sequential bronchoscopic findings, pulmonary function tests, and chest roentgenograms were comparatively analyzed between the two groups. Results: 1) The endobronchial tuberculosis was highly prevalent in young females especially in third decade. 2) Both actively caseating type and the stenotic type without fibrosis was the most common in the bronchoscopic classification. 3) The sequential bronchoscopic findings in steroid group 2 months after treatment showed no significant improvements compared with nonsteroid group. 4) There was no significant difference between the two groups in the sequential bronchoscopic improvements according to bronchoscopic types. 5) We did not find any significant difference in improvements on follow-up pulmonary function tests and simple chest roentgenograms between the two groups 2 month after treatment. 6) There was no significant adverse effect of steroid during the treatment. Conclusion: Combined steroid therapy provably would not influence outcome of the treatment of endobronchial tuberculosis.

Purpose: Endoscopic incision and submucosal dissection (EISD) is a technique that is being implemented for the resection of gastric adenomas and early gastric cancer (EGC). Since EISD requires a high degree of skill and experience, and due to its association with a moderate risk of gastrointestinal bleeding, its use has been limited. The objective of this study is to investigate the clinical benefits of EISD based upon clinical data on the EISD procedure. Materials and Methods: This study was conducted at Soonchunhyang University Hospital and it included 179 gastric adenoma and early gastric carcinoma lesions from 164 patients who had undergone an EISD from February 2003 to May 2005. Results: Among the total of 179 lesions, the distributions of EGC and adenomas were 70.3% (126/179) and 23.4% (42/179) respectively. The sizes of lesions were divided into 10 mm or less, $11{\sim}20\;mm,\;21{\sim}30\;mm$ and greater than 31 mm and each rates are 10.0% (18/179), 46.3% (83/179), 30% (50/179) and 15.0% (28/179). Among 120 cases which could be measured depth of lesion in according to pathologic findings, m1 (0.8%, 1/120), m2 (38.3%, 46/120), m3 (25%, 57/120), sm1 (11.7%, 14/120), sm2 (1.6%, 2/120) were diagnosed as early stages of gastric cancer. The complete resection rate was 85.2% (150/176) and en-bloc resection rate was 96.0% (169/176). Complications as such as perforation and bleeding developed in 4.4%(8/179) and 21.2% (38/179), respectively. Conclusion: EISD is an effective in the endoscopic treatment for gastric adenoma and early gastric cancers. However, further evaluation of this method and long-term follow-up will be necessary for an evaluation of the recurrence rate after resection of a tumor.

Purpose: We are going to establish the efficacy of endoscopic examinations in diagnosing and treating upper GI bleeding in full term neonates. Methods: We retrospectively reviewed newborns who underwent endoscopic examination because of hematemesis from July 1998 to April 2001. Results: Gestational ages were between 38 and 41weeks, and birth weights were between 2,730 and 3,400 gm. Total of 9 patients were reviewed. Endoscopic examination revealed gastric ulcer in 6 cases, multiple erosions in 2 cases and negative finding in 1 case. All 6 gastric ulcers were multiple and among them 2 patients endoscopic hemostatic therapy. No complication due to the procedure was noticed. Five patients recieved transfusions. All 9 cases were cured through conservative and endoscopic therapy without recurrence. Conclusion: The common cause of upper GI hemorrhage in newborns with no preceding disease turns out to be multiple gastric ulcers and the prognosis is good. The endoscopic approach is useful in diagnosing and treating upper GI bleeding in newborns.

62-year-old patient who had past history of endoscopic submucosal dissection for early gastric cancer at September 2008, underwent endoscopic submucosal dissection of esophagus for early esophageal cancer at mid esophagus during health screening service. Because there was a high risk of lymph node metastasis at biopsy results, concurrent chemoradiotherapy was added to endoscopic submucosal dissection. There was a metachronous cancer at mid-esophagus at March 2013. He underwent endoscopic mucosal resection and photodynamic therapy. Concurrentchemoradiotherapy after endoscopic submucosal dissection is an effective treatment method.

현재 국내에서는 Virtual CT endoscopy가 초기단계에 있으므로 앞으로 많은 임상 경험과 data의 축적을 쌓는 것이 중요하다고 보여진다. Virtual CT endoscopy는 조직학적 검사를 위한 병변부위의 조직검사가 불가능한 단점을 갖고 있으나 내시경 검사와 거의 비슷한 소견을 얻을 수 있어 앞으로 병변의 진단 뿐 아니라 병변의 치료 후 추적 검사로도 유용하게 이용되리라 사료된다.
