Since the first transgastric natural orifice transluminal endoscopic surgery was described, various applications and modified procedures have been investigated. Transgastric natural orifice transluminal endoscopic surgery for periotoneoscopy, cholecystectomy, and appendectomy all seem viable in humans, but additional studies are required to demonstrate their benefits and roles in clinical practice. The submucosal tunneling method enhances the safety of peritoneal access and gastric closure and minimizes the risk of intraperitoneal leakage of gastric air and juice. Submucosal tunneling involves submucosal tumor resection and peroral endoscopic myotomy. Peroral endoscopic myotomy is a safe and effective treatment option for achalasia, and the most promising natural orifice transluminal endoscopic surgery procedure. Endoscopic full-thickness resection is a rapidly developing natural orifice transluminal endoscopic surgery procedure for the upper gastrointestinal tract and can be performed with a hybrid natural orifice transluminal endoscopic surgery technique (combining a laparoscopic approach) to overcome some limitations of pure natural orifice transluminal endoscopic surgery. Studies to identify the most appropriate role of endoscopic full-thickness resection are anticipated. In this article, I review the procedures of natural orifice transluminal endoscopic surgery associated with the upper gastrointestinal tract.

Percutaneous Transluminal Angioplasty[PTA] was introduced by Dotter and JudKins [1964], using coaxial catheters of increasing diameter. The remarkable advances in vascular catheter technology over the past several decades have permitted the development. But the application of the balloon catheters carries with it the risk of arterial injury, thrombosis, embolism, and loss of life or limb. A 53-year-old man was admitted to other hospital due to a intermittent claudication in his right leg for 10 years. and PTA was performed at that hospital. Thereafter he was transferred to our hospital because of coldness, pulselessness, rest pain, ischemic ulcer, and progressing gangrene at the anterior aspect of left lower leg. The left lower extremity was salvaged by left ilio-femoral bypass and later saphenous in situ femoro-popliteal bypass.

Percutaneous coronary intervention including intracoronary stenting is currently an accepted treatment modality in the treatment of coronary artery disease and is widely performed to treat the patient with multivessel disease with decreased morbidities and less cost compared with conventional coronary rtery bypass grafting(CABG), Repeated interventions due to restenosis even after successful angioplasty are the major disadvantage of the angioplsty especially when the lesion is located inthe left anterior descending artery(LAD) Recently CABG through left anterior small thoracotomy using the left internal thoracic artery to revascularize the LAD territory without cardiopulmonary bypass so called Minimally Invasive Direct Coronary Artery Bypass(MIDCAB) was intrduced and performed with comparable early outcomes. In this regard the integrated approach with percutaneous coronary intervention and minimally invasive direct coronary artery bypass surgery so called 'Hybrid CABG' was suggested to be an effective treatment in suitable patients with multivessel coronary artery disease. We report three cases of Hybrid CABG.

Background: Previous studies showed differences in healthcare utilization among insurance types. This study aimed to analyze the difference in healthcare utilization for percutaneous transluminal coronary angioplasty inpatients by insurance types after controlling factors affecting healthcare utilization using propensity score matching (PSM). Methods: The 2011 national inpatient sample based on health insurance claims data was used for analysis. PSM was used to control factors influencing healthcare utilization except insurance types. Length of stay and total charges were used as healthcare utilization variables. Patients were divided into National Health Insurance (NHI) and Medical Aid (MA) patients. Factors representing inpatients (gender, age, admission sources, and Elixhauser comorbidity index) and hospitals (number of doctors, number of beds, and location of hospitals) were used as covariates in PSM. Results: Tertiary hospitals didn't show significant difference in length of stay and total charges after PSM between two insurance types. However, MA patients showed significantly longer length of stay than that of NHI patients after PSM in general hospitals. Multivariate regression analysis provided that admission sources, Elixhauser comorbidity index, insurance types, number of doctors, and location of hospitals (province) had significant influences on the length of stay in general hospitals. Conclusion: Study results provided evidences that healthcare utilization was differed by insurance types in general hospitals. Health policy makers will need to prepare interventions to influence the healthcare utilization differences between insurance types.

Purpose: To evaluate the effectiveness of percutaneous transluminal angioplasty (PTA) below the knee as a treatment in diabetic foot gangrene. Materials and Methods: Between May 2003 and May 2006, angiography was performed in 35 diabetic foot gangrene classified as either Wagner grade IV or V. Infrapopliteal PTA was performed in 10 patients among them. Clinical success was defined as prevention of major amputation. Results: Among 25 patients who did not receive infrapopliteal PTA, the major amputation rate is 22% (in one arterial occlusion cases), 50% (in two arterial occlusion cases), 63% (in three arterial occlusion cases), respectively. Infrapopliteal PTA was successfully performed in 8 among 10 patients. Two patients were failed and undergone below-knee amputation. Toe amputation were performed in 2 patients with one arterial occlusion. Out of 6 patients with three arterial occlusions, toe amputations were performed in 4 patients and the other 2 patients were healed through debridement. Conclusion: As a first choice revascularization procedure for limb salvage in diabetic foot gangrene, infrapopliteal PTA can be one of treatment options.

신성 고혈압은 소아기 이차성 고혈압의 흔한 원인이며, 그 중 신동맥 협착에 의한 신혈관성 고혈압은 치료 가능한 고혈압의 가장 흔한 원인이다. 신혈관성 고혈압 치료로 최근 경피적 신동맥 혈관 성형술은 비침습적인 방법으로 각광 받고 있다. 저자들은 작은 직경을 가진 신동맥 분지 혈관 협착에 의한 신혈관성 고혈압 소아에서 관상동맥용으로 쓰이는 풍선 카테터를 이용하여 경피적 신동맥혈관 성형술을 성공적으로 시행한 경험을 하였으므로 보고하는 바이다.

Objective : Vasospasm of cerebral vessels remains a major source of morbidity and mortality after an aneurysmal subarachnoid hemorrhage (SAH). The purpose of this study was to evaluate the safety and efficacy of transluminal balloon angioplasty (TBA) for SAH-induced vasospasm. Methods : Eleven patients with an angiographically confirmed significant vasospasm (>50% vessel narrowing and clinical deterioration) were studied. A total of 54 vessel segments with significant vasospasm were treated by TBA. Digital subtraction angiography was used to confirm the presence of vasospasm, and TBA was performed to dilate vasospastic arteries. Medical and angiographic reports were reviewed to determine technical efficacy and for procedural complications. Results : TBA using Hyper-Glide or Hyper-Form balloons (MicroTherapeutics, Irvine, CA) was successfully accomplished in 88.9% vasospastic segments (48 of 54), namely, in the distal internal carotid artery (100%, n=7), the middle cerebral artery (100%), including the M1 (n=10), M2 (n=10), and M3 segments (n=4), in the vertebral artery (100%, n=2), basilar artery (100%, n=1), and in the anterior cerebral artery (ACA), including the A1 (66%), A2 (66%), and A3 segments (100%). Vessel diameters significantly increased after TBA. There were no cases of vessel rupture or thromboembolic complications. GCS at one day after TBA showed an improvement in all patients except one. Conclusion : This study suggests that TBA using Hyper-Glide or Hyper-Form balloons is a safe and effective treatment for subarachnoid hemorrhage-induced cerebral vasospasm.
