| 16 | High-grade pancreatic intraepithelial neoplasia diagnosed based on changes in magnetic resonance cholangiopancreatography findings:A case report显示文摘BACKGROUND High-grade pancreatic intraepithelial neoplasia(PanIN)exhibits no mass and is not detected by any examination modalities.However,it can be diagnosed by pancreatic juice cytology from indirect findings.Most previous cases were diagnosed based on findings of a focal stricture of the main pancreatic duct(MPD)and caudal MPD dilatation and subsequent pancreatic juice cytology using endoscopic retrograde cholangiopancreatography(ERCP).We experienced a case of high-grade PanIN with an unclear MPD over a 20-mm range,but without caudal MPD dilatation on magnetic resonance cholangiopancreatography(MRCP).CASE SUMMARY A 60-year-old female patient underwent computed tomography for a follow-up of uterine cancer post-excision,which revealed pancreatic cysts.MRCP revealed an unclear MPD of the pancreatic body at a 20-mm length without caudal MPD dilatation.Thus,course observation was performed.After 24 mo,MRCP revealed an increased caudal MPD caliber and a larger pancreatic cyst.We performed ERCP and detected atypical cells suspected of adenocarcinoma by serial pancreatic juice aspiration cytology examination.We performed a distal pancreatectomy and obtained a histopathological diagnosis of high-grade PanIN.Pancreatic parenchyma invasion was not observed,and curative resection was achieved.CONCLUSION High-grade Pan-IN may cause MPD narrowing in a long range without caudal MPD dilatation. | Nao Furuya Atsushi Yamaguchi Naohiro Kato Syuhei Sugata Takuro Hamada Takeshi Mizumoto Yuzuru Tamaru Ryusaku Kusunoki Toshio Kuwai Hirotaka Kouno Kazuya Kuraoka Yoshiyuki Shibata Sho Tazuma Takeshi Sudo Hiroshi Kohno Shiro Oka | 2024 | World Journal of Clinical Cases2024,12,8: | 0 |
| 17 | Newly developed self-expandable Niti-S MD colonic metal stent for malignant colonic obstruction显示文摘BACKGROUND Colonic stents are increasingly used to treat acute malignant colonic obstructions.The Wall Flex and Niti-S D type stents are the commonly used self-expandable metallic stents available in Japan since 2012.Wall Flex stent has a risk of stentrelated perforation because of its axial force,while the Niti-S D type stent has a risk of obstructive colitis because of its weaker radial force.Niti-S MD type stents not only overcome these limitations but also permit delivery through highly flexible-tipped smaller-caliber colonoscopes.AIM To compare the efficacy and safety of the newly developed Niti-S MD type colonic stents.METHODS This single-center retrospective observational study included 110 patients with endoscopic self-expandable metallic stents placed between November 2011 and December 2018:Wall Flex(Group W,n=37),Niti-S D type(Group N,n=53),and Niti-S MD type(Group MD,n=20).The primary outcome was clinical success,defined as a resolution of obstructive colonic symptoms,confirmed by clinical and radiological assessment within 48 h.The secondary outcome was technical success,defined as accurate stent placement with adequate stricture coverage on the first attempt without complications.RESULTS The technical success rate was 100%in Groups W,N,and MD,and the overall clinical success rate was 89.2%(33/37),96.2%(51/53),and 100%(20/20)in Groups W,N,and MD,respectively.Early adverse events included pain(3/37,8.1%),poor expansion(1/37,2.7%),and fever(1/37,2.6%)in Group W and perforation due to obstructive colitis(2/53,3.8%)in Group N(likely due to poor expansion).Late adverse events(after 7 d)included stent-related perforations(4/36,11.1%)and stent occlusion(1/36,2.8%)in Group W and stent occlusion(2/51,3.9%)in Group N.The stent-related perforation rate in Group W was significantly higher than that in Group N(P<0.05).No adverse event was observed in Group MD.CONCLUSION In our early and limited experience,the newly developed Niti-S MD type colonic stent was effective and safe for treating acute malignant colonic obstruction. | Yuki Miyasako Toshio Kuwai Sauid Ishaq Kanae Tao Hirona Konishi Ryoichi Miura Yuki Sumida Kazutaka Kuroki Yuzuru Tamaru Ryusaku Kusunoki Atsushi Yamaguchi Hirotaka Kouno Hiroshi Kohno | 2020 | World Journal of Gastrointestinal Surgery2020,12,4: | 0 |
