| 1 | Successful balloon-occluded retrograde transvenous obliteration for bleeding duodenal varices using cyanoacrylate显示文摘A 76-year-old woman with hepatitis C cirrhosis presented with tarry stools and hematemesis.An endoscopy demonstrated bleeding duodenal varices in the second portion of the duodenum.Contrast-enhanced computed tomography revealed markedly tortuous varices around the wall in the duodenum.Several afferent veins appeared to have developed,and the right ovarian vein draining into the inferior vena cava was detected as an efferent vein.Balloon-occluded retrograde transvenous obliteration (BRTO) of the varices using cyanoacrylate was successfully performed in combination with the temporary occlusion of the portal vein.Although no previous publications have used cyanoacrylate as an embolic agent for BRTO to control bleeding duodenal varices,this strategy can be considered as an alternative procedure to conventional BRTO using ethanolamine oleate when numerous afferent vessels that cannot be embolized are present. | Rintaro Hashimoto Keitaro Sofue Yoshito Takeuchi Kentaro Shibamoto Yasuaki Arai | 2013 | World Journal of Gastroenterology2013，19，6： | 3 |

| 5 | Endoscopic ultrasound-through-the-needle biopsy in pancreatic cystic lesions: A large single center experience显示文摘BACKGROUND Establishing a diagnosis of pancreatic cystic lesions(PCLs)preoperatively still remains challenging.Recently,endoscopic ultrasound(EUS)-through-the-needle biopsy(EUS-TTNB)using microforceps in PCLs has been made available.AIM To assess the efficacy and safety of EUS-TTNB in the diagnosis of PCLs.METHODS We retrospectively collected data of patients with PCLs who underwent both EUS-fine-needle aspiration(FNA)for cytology and EUS-TTNB at our institution since 2016.EUS-FNA for cytology was followed by EUS-TTNB in the same session.Evaluation of the cyst location,primary diagnosis,adverse events,and comparison between the cytologic fluid analyses and histopathology was performed.Technical success of EUS-TTNB was defined as visible tissue present after biopsy.Clinical success was defined as the presence of a specimen adequate to make a histologic or cytologic diagnosis.RESULTS A total of 56 patients(mean age 66.9±11.7,53.6%females)with PCLs were enrolled over the study period.The mean cyst size was 28.8 mm(12-85 mm).The EUS-TTNB procedure was technically successful in all patients(100%).The clinical success rate using EUS-TTNB was much higher than standard EUS-FNA,respectively 80.4%(45/56)vs 25%(14/56).Adverse events occurred in 2 patients(3.6%)who developed mild pancreatitis that resolved with medical therapy.Using TTNB specimens,23 of 32 cases(71.9%)with intraductal papillary mucinous neoplasm were further differentiated into gastric type(19 patients)and pancreaticobiliary type(4 patients)based on immunochemical staining.CONCLUSION EUS-TTNB for PCLs was technically feasible and had a favorable safety profile.Furthermore,the diagnostic yield for PCLs was much higher with EUS-TTNB than standard EUS-FNA cytology and fluid carcinoembryonic antigen.EUSTTNB should be considered as an adjunct to EUS-FNA and cytologic analysis in the diagnosis and management of PCLs. | Rintaro Hashimoto John G Lee Kenneth J Chang Nabil El Hage Chehade Jason B Samarasena | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，11： | 0 |
| 6 | Implementation of an educational program for pancreaticoduodenectomy in a university hospital: a retrospective observational study显示文摘Objective:No ideal training system exists for pancreaticoduodenectomy(PD).We developed an educational system that uses an objective structured assessment of technical skills.Methods:This retrospective observational study was conducted using the data of consecutive trainees and patients who underwent PD from 2007 to 2013 in Kansai Medical University Hospital.The total score on the task checklist(21 parameters)for measuring technical performance during PD by self assessment and instructor assessment was compared between junior(JN)and hepatobiliary pancreatic(HBP)trainees at a university hospital.Surgical outcomes of 303 PDs(2007-2013)were also compared among JN trainees,HBP trainees,and instructors,and the present position of the trainees was investigated.This study was approved by the institutional review board of Kansai Medical University on May 26,2020.Results:The self-assessment score on the task checklist was significantly higher for the HBP trainees than for the JN trainees on all parts of PD(P<.001).The discrepancy between self-assessment and instructor assessment improved in 3 JN trainees after experience with the first 5 PDs.Although total score curves rose to the right in the JN group,scores in the HBP group were stable,at 70 or higher,which correlated with the instructor assessment.The 90-day and 30-day mortality rates were 1.6%and 0.3%,respectively.Mortality and morbidity after PD did not differ between the JN and HBP trainees or between the instructors and the trainees.Four of 10 trainees became board-certified expert surgeons of the Japanese Society of Hepatobiliary Pancreatic Surgery.Conclusion:These results indicated good construct validity of the task checklist system.This program was safely and effectively implemented in terms of surgical outcomes and final outcomes of trainees becoming board-certified expert surgeons. | Sohei Satoi Tomohisa Yamamoto So Yamaki Satoshi Hirooka Daisuke Hashimoto Tatsuma Sakaguchi Hironori Ryota Rintaro Yui Kazuto Sakuramoto Hideyuki Matsushima Hiroaki Yanagimoto Hideyoshi Toyokawa Taku Michiura Kentaro Inoue Mitsugu Sekimoto | 2021 | Journal of Pancreatology2021，4，2： | 0 |
