Han Saem Jeong, Jae Hyun Jung, Gwan Gyu Song, Sung Jae Choi, Soon Jun Hong
BACKGROUND: Symptomatic or significant vascular lesions of Takayasu arteritis (TA) need interventions. Although percutaneous transluminal angioplasty with balloon is a less invasive and safe method, stent implantation in TA can be an alternative option. However, superiority between balloon angioplasty and stenting in TA is not conclusive. METHODS: A meta-analysis comparing balloon angioplasty and stenting outcomes was performed using the MEDLINE and EMBASE databases...

With the widespread introduction of minimally invasive surgery (MIS) in late 1987 by laparoscopic cholecystectomy, the practice and expectation of general surgery were changed forever. As the development of scientific technology, new techniques of MIS have sprung up all around the world. 3D laparoscopy surgery, natural orifice transluminal endoscopic surgery, da Vinci surgical system and other new technologies also need time to be verified, and this is the only way all new things should get though. They are very unique in their own right, and all have advantages and disadvantages...

Recently, natural orifice transluminal endoscopic surgery (NOTES) has been applied in thyroid surgery with transoral access. The benefit of transoral endoscopic thyroidectomy is the potential for scar-free surgery. However, there are many concerns over some aspects, such as infection, recurrent laryngeal nerve injury, and oncological outcome. In this paper, we have reviewed the development history and the current clinical evidence of this innovative surgery. We conclude that the transoral endoscopic thyroidectomy vestibular approach (TOETVA) is feasible and can be considered no longer an experimental operation...

Cardiovascular diseases including atherosclerosis are a major financial and health burden globally. Inflammation associated with atherosclerosis results in the development of plaques that can rupture causing thrombosis, stroke, or death. The most widely used treatment for the removal of atherosclerotic plaques is percutaneous transluminal coronary angioplasty (PTCA) with or without stenting. Although this is a safer and minimally invasive method, restenosis and intimal hyperplasia after interventional procedure remains a major hurdle and more refined approaches are needed...

Brightness analysis of fluorescence fluctuation experiments has been used to successfully measure the oligomeric state of proteins at the plasma membrane, in the nucleoplasm, and in the cytoplasm of living cells. Here we extend brightness analysis to the nuclear envelope (NE), a double membrane barrier separating the cytoplasm from the nucleoplasm. Results obtained by applying conventional brightness analysis to fluorescently tagged proteins within the NE exhibited an unusual concentration dependence. Similarly, the autocorrelation function of the fluorescence fluctuations exhibited unexpected changes with protein concentration...

BACKGROUND: Hepatic artery stenosis (HAS) after liver transplantation can progress to hepatic artery thrombosis (HAT) and a subsequent 30% to 50% risk of graft loss. Although endovascular treatment of severe HAS after liver transplantation has emerged as the dominant method of treatment, the potential risks of these interventions are poorly described. METHODS: A retrospective review of all endovascular interventions for HAS after liver transplantation between August 2009 and March 2016 was performed at a single institution, which has the largest volume of liver transplants in the United States...

BACKGROUND: Early detection of acute ischaemia through non-invasive methods remains a challenge in health research. Ischaemic condition caused by a decrease in the blood supply in a cardiac region induces hypoxia and metabolic abnormalities that contribute to the electrical instability of the heart and to the development of slow conduction in damaged tissue. METHODS: Herein, a percutaneous transluminal coronary angiography (PTCA) is considered as a model of supply ischaemia...

Thrombus exerts a major impact on the performance and outcome of primary and rescue interventions in acute ST-elevation myocardial infarction. Although the optimal treatment of thrombotic lesions is still controversial, thrombus aspiration provides an effective method to achieve successful reperfusion during primary angioplasty. We compared clinical and angiographic outcomes in 286 patients with acute ST-elevation myocardial infarction undergoing primary percutaneous transluminal coronary angioplasty (PTCA) and thrombus aspiration with those who underwent conventional PTCA without thrombus aspiration...

Patients with coronary artery aneurysms (CAAs) resulting from Kawasaki disease (KD) are at risk for thrombosis and myocardial infarction. Current guidelines recommend CAA diameter ≥8 mm as the criterion for initiating systemic anticoagulation. Transluminal attenuation gradient (TAG) analysis has been proposed as a noninvasive method for evaluating functional significance of coronary stenoses using computerized tomography angiography (CTA), but has not previously been used in CAA. We hypothesized that abnormal hemodynamics in CAA caused by KD could be quantified using TAG analysis...

Endoscopic ultrasound-guided biliary drainage (EUS-BD) is increasingly used as an alternative in patients with biliary obstruction who fail standard endoscopic retrograde cholangiopancreatography (ERCP). The two major endoscopic approach routes for EUS-BD are the transgastric intrahepatic and transduodenal extrahepatic approaches. Biliary drainage can be achieved by three different methods, transluminal biliary stenting, transpapillary rendezvous technique, and antegrade biliary stenting. The choice of approach route and drainage method depends on individual anatomy, underlying disease, and location of the biliary stricture...

Laparoscopic surgery has been increasingly used in rectal cancer surgery. Though there are still some controversies, most of the research results support that the outcome is similar for rectal cancer patients with either laparoscopic or open surgery, in term of short-term such as safety and efficacy and long-term such as oncologic outcome. Standardization of laparoscopic training together with the comprehensive management concept are the prerequisites of laparoscopic rectal cancer surgery. Those doctors who do minimally invasive surgery should follow the rationale that smaller incision and sphincter preservation are secondary to safety and oncological result of the patients...
