1Current clinical management of gastrointestinal stromal tumor显示文摘Gastrointestinal stromal tumors(GISTs) are the most common malignant subepithelial lesions(SELs) of the gastrointestinal tract. They originate from the interstitial cells of Cajal located within the muscle layer and are characterized by over-expression of the tyrosine kinase receptor KIT. Pathologically, diagnosis of a GIST relies on morphology and immunohistochemistry [KIT and/or discovered on gastrointestinal stromal tumor 1(DOG1) is generally positive]. The prognosis of this disease is associated with the tumor size and mitotic index. The standard treatment of a GIST without metastasis is surgical resection. A GIST with metastasis is usually only treated by tyrosine kinase inhibitors without radical cure; thus, early diagnosis is the only way to improve its prognosis. However, a GIST is usually detected as a SEL during endoscopy, and many benign and malignant conditions may manifest as SELs. Conventional endoscopic biopsy is difficult for tumors without ulceration. Most SELs have therefore been managed without a histological diagnosis. However, a favorable prognosis of a GIST is associated with early histological diagnosis and R0 resection. Endoscopic ultrasonography(EUS) and EUS-guided fine needle aspiration(EUSFNA) are critical for an accurate diagnosis of SELs. EUSFNA is safe and effective in enabling an early histological diagnosis and adequate treatment. This review outlines the current evidence for the diagnosis and management of GISTs, with an emphasis on early management of small SELs.Kazuya Akahoshi Masafumi Oya Tadashi Koga Yuki Shiratsuchi 2018World Journal of Gastroenterology2018,24,26:70
2Endoscopic ultrasonography for gastric submucosal lesions显示文摘Gastric submucosal tumors(SMTs) are a rather frequent finding,occurring in about 0.36%of routine upper GIendoscopies.Endoscopic ultrasonography(EUS) has emerged as a reliable investigative procedure for evaluation of these lesions.Diagnostic EUS has the ability to differentiate intramural tumors from extraluminal compressions and can also show the layer of origin of gastric SMTs.Tumors can be further characterized by their layer of origin,echo pattern and margin.EUS-risk criteria of their malignant potential are presented,although the emergence of EUS-FNA has opened new indications for transmural tissue diagnosis and expanded the possibilities of EUS in SMTs of the stomach.Tissue diagnosis should address whether the SMT is a Gastrointestinal stromal tumour(GIST) or another tumor type and evaluate the malignant potential of a given GIST.However,there seems to be a lack of data on the optimal strategy in SMTs suspected to be GISTs with a negative EUS-FNA tissue diagnosis.The current management strategies,as well as open questions regarding their treatment are also presented.Ioannis S Papanikolaou Konstantinos Triantafyllou Anastasia Kourikou Thomas Rsch 2011World Journal of Gastrointestinal Endoscopy2011,3,5:44

15Gastrointestinal stromal tumor of the stomach:How to manage?显示文摘Gastrointestinal stromal tumor (GIST) is one of the most common malignant mesenchymal tumors of the stomach. Prognosis of this disease is related to tumor size and mitotic activity and early diagnosis is the only way to improve it.Diagnosis of GIST always requires histological and immunohistochemical confirmation as no imaging modalities can diagnose it conclusively.Endoscopic forceps biopsy results are frequently negative. Endoscopic ultrasound-guided fine needle asp- iration (EUS-FNA) is a technique which allows tissue samples to be obtained with minimal risks and is accurate in the diagnosis of GIST. From the point of view of the endoscopist, aggressive use of EUS-FNA is the only promising way to allow early diagnosis and early treatment of this disease.Kazuya Akahoshi Masafumi Oya 2010World Journal of Gastrointestinal Endoscopy2010,2,8:16
16超声内镜技术在消化系统疾病诊断中的应用显示文摘超声内镜技术应用于临床已30余载,其在诊断消化系统疾病中应用广泛。近年来,以超声内镜为基础的诊断技术不断发展和完善,超声内镜相关诊断技术主要包括超声内镜弹性成像技术 (endoscopic ultrasound elastography, EUS-EG)、造影增强超声内镜(contrast-enhanced endoscopic ultrasound,CE-EUS)、谐波造影增强超声内镜( contrast harmonicendoscopic ultrasound, CH-EUS)和超声内镜引导下细针穿刺活检术(endoscopic ultrasound guided fine needle aspiration,EUS-FNA)等。孙悦 秘建威 赵东强 2018中华超声影像学杂志2018,27,4:16
17Bioinspired Adhesive and Antibacterial Microneedles for Versatile Transdermal Drug Delivery显示文摘Microneedles have attracted increasing interest among various medical fields due to their painless,noninvasive,and efficient way of drug delivery.However,practical applications of these microneedles in different epidermal locations and environments are still restricted by their low adhesion and poor antimicrobial activity.Here,inspired by the antibacterial strategy of Paenibacillus polymyxa and adhesion mechanisms of mussel byssi and octopus tentacles,we develop hierarchical microneedles with multifunctional adhesive and antibacterial abilities.With polydopamine hydrogel as the microneedle base and a loop of suctioncup-structured concave chambers encircling each microneedle,the generated microneedles can fit the skin well;keep strong adhesion in dry,moist,and wet environments;and realize self-repair after being split into two parts.Besides,as polymyxin is loaded into both the hydrogel tips and the polydopamine base,the microneedles are endowed with excellent ability to resist common bacteria during storage and usage.We have demonstrated that these microneedles not only showed excellent adhesion when applied to knuckles and ideal antibacterial activity but also performed well in drug-sustained release and treatment for the osteoarthritis rat model.These results indicate that bioinspired multifunctional microneedles will break through the limitation of traditional methods and be ideal candidates for versatile transdermal drug delivery systems.Xiaoxuan Zhang Guopu Chen Yunru Yu Lingyu Sun Yuanjin Zhao 2020Research2020,,1:14
18Endoscopic incisional therapy for benign esophageal strictures: Technique and results显示文摘Benign esophageal strictures refractory to the conventional balloon or bougie dilatation may be subjected to various adjunctive modes of therapy, one of them being endoscopic incisional therapy(EIT). A proper delineation of the stricture anatomy is a prerequisite. A host of electrocautery and mechanical devices may be used, the most common being the use of needle knife, either standard or insulated tip. The technique entails radial incision and cutting off of the stenotic rim. Adjunctive therapies, to prevent re-stenosis, such as balloon dilatation, oral or intralesional steroids or argon plasma coagulation can be used. The common strictures where EIT has been successfully used are Schatzki's rings(SR) and anastomotic strictures(AS). Short segment strictures(< 1 cm) have been found to have the best outcome. When compared with routine balloon dilatation, EIT has equivalent results in treatment na?ve cases but better long term outcome in refractory cases. Anecdotal reports of its use in other types of strictures have been noted. Post procedure complications of EIT are mild and comparable to dilatation therapy. As of the current evidence, incisional therapy can be used for management of refractory AS and SR with relatively short stenosis(< 1 cm) with good safety profile and acceptable long term patency.Jayanta Samanta Narendra Dhaka Saroj Kant Sinha Rakesh Kochhar 2015World Journal of Gastrointestinal Endoscopy2015,7,19:14
19Precut sphincterotomy:A reliable salvage for difficult biliary cannulation显示文摘Even experienced endoscopists have 90% success in achieving deep biliary cannulation with standard methods. Biliary cannulation may become difficult in 10%-15% of patients with biliary obstruction and pre- cut (access) sphincterotomy is frequently chosen as a rescue treatment in these cases. Generally, precut sphincterotomy ensures a rate of 90%-100% success- ful deep biliary cannulation. The precut technique has been performed as either a fistulotomy with a needle knife sphincterotome or as a transpapillary septotomy with a standard sphincterotome. Both methods have similar efficacy and complication rates when adminis- tered to the proper patient. Although precut sphincter- otomy ensures over 90% success of biliary cannula- tion, it has been characterized as an independent risk factor for pancreatitis. The complications of the precut technique are not limited to pancreatitis. Two more important ones, bleeding and perforation, are also re- ported in some publications as being observed more commonly than during standard sphincterotomy. It is also reported that precut sphincterotomy increases morbidity when performed in patients without dilata- tion of their biliary tract. Nevertheless, precut sphinc- terotomy is a good alternative as a rescue method in the setting of a failed standard cannulation method. This paper discusses the technical details, timing, ef- ficacy and potential complications of precut sphincter- otomy.Ulku Saritas Yucel Ustundag Ferda Harmandar 2013World Journal of Gastroenterology2013,19,1:13
