| 1 | Endoscopic papillary balloon dilation:Revival of the old technique显示文摘Radiologists first described the removal of bile duct stones using balloon dilation in the early 1980s.Recently,there has been renewed interest in endoscopic balloon dilation with a small balloon to avoid the complications of endoscopic sphincterotomy(EST)in young patients undergoing laparoscopic cholecystectomy.However,there is a disparity in using endoscopic balloon papillary dilation(EPBD)between the East and the West,depending on the origin of the studies.In the early 2000s,EST followed by endoscopic balloon dilation with a large balloon was introduced to treat large or difficult biliary stones.Endoscopic balloon dilation with a large balloon has generally been recognized as an effective and safe method,unlike EPBD.However,fatal complications have occurred in patients with endoscopic papillary large balloon dilation(EPLBD).The safety of endoscopic balloon dilation is still a debatable issue.Moreover,guidelines of indications and techniques have not been established in performing endoscopic balloon dilation with a small balloon or a large balloon.In this article,we discuss the issue of conventional and large balloon endoscopic dilation.We also suggest the indications and optimal techniques of EPBD and EPLBD. | Seung Uk Jeong Sung-Hoon Moon Myung-Hwan Kim | 2013 | World Journal of Gastroenterology2013，19，45： | 10 |

| 3 | Avoiding heating interference and guided thermal conduction in stretchable devices using thermal conductive composite islands显示文摘The miniaturization and high integration of devices demand significant thermal management materials.Current technologies for the thermal management of electronics show some limitations in the case of multiple chip arrays.A device in multiple chip array is affected by heat from adjacent devices,along with thermal conductive composite.To address this problem,we present a nano composite of aligned boron nitride(BN)nanosheet islands with porous polydimethylsiloxane(PDMS)foam to have mechanical stability and non-thermal interference.The islands of tetrahedrally-structured BN in the composite have a high thermal conductivity of 1.219 W·m^(-1)·K^(-1) in the through-plane direction(11.234W·m^(-1)·K^(-1)in the in-plane direction)with 16 wt.%loading of BN.On the other hand,porous PDMS foam has a low thermal conductivity of 0.0328W·m^(-1)·K^(-1) in the through-plane direction at 70%porosity.Heat pathways are then formed only in the structured BN islands of the composite.The porous PDMS foam can be applied as a thermal barrier between structured BN islands to inhibit thermal interference in multiple device arrays.Furthermore,this composite can maintain selective thermal dissipation performance with 70%tensile strain.Another beauty of the work is that it could have guided heat dissipation by assembling of multiple layers which have high vertical thermal conductive islands,while inhibiting thermal interference.The selective heat dissipating composite can be applied as a heatsink for multiple chip arrays electronics. | Seung Ji Kang Haeleen Hong Chanho Jeong Ju Seung Lee Hyewon Ryu Jae-hun Yang Jong Uk Kim Yiel Jae Shin Tae-il Kim | 2021 | Nano Research2021，14，9： | 4 |

| 6 | Forward-viewing endoscopic ultrasound-guided NOTES interventions: A study on peritoneoscopic potential显示文摘AIM:To evaluate the feasibility of diagnostic and therapeutic transgastric(TG)peritoneoscopic interventions with a forward-viewing endoscopic ultrasound(FV-EUS).METHODS:This prospective endoscopic experimental study used an animal model.Combined TG peritoneoscopic interventions and EUS examination of the intraabdominal organs were performed using an FV-EUS on 10 animal models(1 porcine and 9 canine).The procedures carried out include EUS evaluation and endoscopic biopsy of intraperitoneal organs,EUS-guided fine needle aspiration(EUS-FNA),EUS-guided radiofrequency ablation(EUS-RFA),and argon plasma coagulation(APC)for hemostatic control.The animals were kept alive for 7 d,and then necropsy was performed to evaluate results and complications.RESULTS:In all 10 animals,TG peritoneoscopy,followed by endoscopic biopsy for the liver,spleen,abdominal wall,and omentum,was performed successfully.APC helped control minor bleeding.Visualization of intra-abdominal solid organs with real-time EUS was accomplished with ease.Intraperitoneal EUS-FNA was successfully performed on the liver,spleen,and kidney.Similarly,a successful outcome was achieved with EUSRFA of the hepatic parenchyma.No adverse events were recorded during the study.CONCLUSION:Peritoneoscopic natural orifice transluminal endoscopic surgery(NOTES)interventions through FV-EUS were feasible in providing evaluation and performing endoscopic procedures.It promises potential as a platform for future EUS-based NOTES. | Seung Uk Jeong Hassanuddin Aizan Tae Jun Song Dong Wan Seo Su-Hui Kim Do Hyun Park Sang Soo Lee Sung Koo Lee Myung-Hwan Kim | 2013 | World Journal of Gastroenterology2013，19，41： | 0 |
