1Pancreatic stents for the prevention of post-endoscopic retrograde cholangiopancreatography pancreatitis should be inserted up to the pancreatic body or tail显示文摘AIM To investigate the location to which a pancreatic stent should be inserted to prevent post-endoscopic retrograde cholangiopancreatography(ERCP) pancreatitis(PEP).METHODS Over a ten-year period at our hospital, 296 patients underwent their first ERCP procedure and had a pancreatic stent inserted; this study included 147 patients who had ERCP performed primarily for biliary investigation and had a pancreatic stent inserted to prevent PEP. We dividedthese patients into two groups: 131 patients with a stent inserted into the pancreatic head(head group) and 16 patients with a stent inserted up to the pancreatic body or tail(body/tail group). Patient characteristics and ERCP factors were compared between the groups.RESULTS Pancreatic amylase isoenzyme(p-AMY) levels in the head group were significantly higher than those in the body/tail group [138.5(7.0-2086) vs 78.5(5.0-1266.5), P = 0.03] [median(range)]. No cases of PEP were detected in the body/tail group [head group, 12(9.2%)]. Of the risk factors for post-ERCP hyperamylasemia(≥ p-AMY median, 131 IU/L), procedure time ≥ 60 min [odds ratio(OR) 2.65, 95%CI: 1.17-6.02, P = 0.02) and stent insertion into the pancreatic head(OR 3.80, 95%CI: 1.12-12.9, P = 0.03) were identified as independent risk factors by multivariate analysis.CONCLUSION Stent insertion up to the pancreatic body or tail reduces the risk of post-ERCP hyperamylasemia and may reduce the risk of PEP.Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Ko Watanabe Jun Nakamura Hitomi Kikuchi Yuichi Waragai Mika Takasumi Takuto Hikichi Hiromasa Ohira 2018World Journal of Gastroenterology2018,24,22:13
2Efficacy of endoscopic ultrasonography-guided fine needle aspiration for pancreatic neuroendocrine tumor grading显示文摘AIM: To evaluate the efficacy of endoscopic ultrasonography-guided fine needle aspiration(EUS-FNA) for grading pancreatic neuroendocrine tumors(PNETs).METHODS: A total of 22 patients were diagnosed with PNET by EUS-FNA between October 2001 and December 2013 at Fukushima Medical University Hospital.Among these cases,we targeted 10 PNET patients who were evaluated according to the World Health Organization(WHO) 2010 classification.Surgery was performed in eight patients,and chemotherapy was performed in two patients due to multiple liver metastases.Specimens obtained by EUS-FNA were first stained with hematoxylin and eosin and then stained with chromogranin,synaptophysin,CD56,and Ki-67.The specimens were graded by the Ki-67 index according to the WHO 2010 classification.Specimens obtained by surgery were graded by the Ki-67 indexand mitotic count(WHO 2010 classification).For the eight specimens obtained by EUS-FNA,the Ki-67 index results were compared with those obtained by surgery.In the two cases treated with chemotherapy,the effects and prognoses were evaluated.RESULTS: The sampling rate for histological diagnosis by EUS-FNA was 100%.No adverse effects were observed.The concordance rate between specimens obtained by EUS-FNA and surgery was 87.5%(7/8).Fo r t h e t w o c a s e s t re a t e d w i t h c h e m o t h e ra p y,case 1 received somatostatin analog therapy and transcatheter arterial infusion(TAI) targeting multiple liver metastases.Subsequent treatment consisted of everolimus.During chemotherapy,the primary tumor remained unconfirmed,although the multiple liver metastases diminished dramatically.Case 2 was classified as neuroendocrine carcinoma(NEC) according to the Ki-67 index of a specimen obtained by EUS-FNA; therefore,cisplatin and irinotecan therapy was started.However,severe adverse effects,including renal failure and diarrhea,were observed,and the therapy regimen was changed to cisplatin and etoposide.TAI targeting multiple liver metastases was performed.Although the liver metastases diminished,the primary tumor remained unconfirmed.These chemotherapy regimens had immediate effects for both unresectable neuroendocrine tumor(NET) and NEC cases.These two subjects are still alive.CONCLUSION: EUS-FNA was effective for PNET diagnosis and Ki-67 index grading for WHO 2010 classification,enabling informed decisions on unresectable PNET treatment by identifying NET or NEC.Mitsuru Sugimoto Tadayuki Takagi Takuto Hikichi Rei Suzuki Ko Watanabe Jun Nakamura Hitomi Kikuchi Naoki Konno Yuichi Waragai Hiroyuki Asama Mika Takasumi Hiroshi Watanabe Katsutoshi Obara Hiromasa Ohira 2015World Journal of Gastroenterology2015,21,26:6

4Survival of geriatric patients after percutaneous endoscopic gastrostomy in Japan显示文摘AIM: To examine the long term survival of geriatric patients treated with percutaneous endoscopic gastrostomy (PEG) in Japan. METHODS: We retrospectively included 46 Japanese community and tertiary hospitals to investigate 931 consecutive geriatric patients (≥ 65 years old) with swallowing difficulty and newly performed PEG between Jan 1st 2005 and Dec 31st 2008. We set death as an outcome and explored the associations among patient’s characteristics at PEG using log-rank tests and Cox proportional hazard models. RESULTS: Nine hundred and thirty one patients were followed up for a median of 468 d. A total of 502 deaths were observed (mortality 53%). However, 99%, 95%, 88%, 75% and 66% of 931 patients survived more than 7, 30, 60 d, a half year and one year, respectively. In addition, 50% and 25% of the patients survived 753 and 1647 d, respectively. Eight deaths were considered as PEG-related, and were associated with lower serum albumin levels (P = 0.002). On the other hand, among 28 surviving patients (6.5%), PEG was removed. In a multivariate hazard model, older age [hazard ratio (HR), 1.02; 95% confidence interval (CI), 1.00-1.03; P = 0.009], higher C-reactive protein (HR, 1.04; 95% CI: 1.01-1.07; P = 0.005), and higher blood urea nitrogen (HR, 1.01; 95% CI: 1.00-1.02; P = 0.003) were significant poor prognostic factors, whereas higher albumin (HR, 0.67; 95% CI: 0.52-0.85; P = 0.001), female gender (HR, 0.60; 95% CI: 0.48-0.75; P < 0.001) and no previous history of ischemic heart disease (HR, 0.69; 95% CI: 0.54-0.88, P = 0.003) were markedly better prognostic factors. CONCLUSION: These results suggest that more than half of geriatric patients with PEG may survive longer than 2 years. The analysis elucidated prognostic factors.Yutaka Suzuki Seryna Tamez Akihiko Murakami Akihiko Taira Akihiro Mizuhara Akira Horiuchi Chie Mihara Eiji Ako Hirohito Muramatsu Hitoshi Okano Hitoshi Suenaga Kazuaki Jomoto Junya Kobayashi Katsunari Takifuji Kazuhiro Akiyama Koh Tahara Koji Onishi Makoto Shimazaki Masami Matsumoto Masashi Ijima Masato Murakami Masato Nakahori Michiaki Kudo Michio Maruyama Mikako Takahashi Naohiro Washizawa Shigeru Onozawa Satoshi Goshi Satoyoshi Yamashita Shigeki Ono Shin Imazato Shinji Nishiwaki Shuichirou Kitahara Takao Endo Takao Iiri Takeshi Nagahama Takuto Hikichi Tatsuya Mikami Tetsuo Yamamoto Tetsushi Ogawa Tomoko Ogawa Tomoyuki Ohta Toshifumi Matsumoto Toshiroh Kura Tsutomu Kikuchi Tsuyoshi Iwase Tsuyotoshi Tsuji Yukio Nishiguchi Mitsuyoshi Urashima 2010World Journal of Gastroenterology2010,16,40:4
5An automated spring-loaded needle for endoscopic ultrasound-guided abdominal paracentesis in cancer patients显示文摘AIM: To evaluate the feasibility of using an automatedspring-loaded needle device for endoscopic ultrasound(EUS)-guided abdominal paracentesis(EUS-P) to see if this would make it easier to puncture the mobile and lax gastric wall for EUS-P.METHODS: The EUS database and electronic medical records at Fukushima Medical University Hospital were searched from January 2001 to April 2011. Patients with a history of cancer and who underwent EUS-P using an automated spring-loaded needle device with a 22-gauge puncture needle were included. The needle was passed through the instrument channel and advanced through the gastrointestinal wall under EUS guidance into the echo-free space in the abdominal cavity and ascitic fluid was collected. The confirmed diagnosis of malignant ascites included positive cytology and results from careful clinical observation for at least 6 mo in patients with negative cytology. The technical success rate, cytology results and complications were evaluated.RESULTS: We found 11 patients who underwent EUS-P with an automated spring-loaded needle device. In 4 cases, ascites was revealed only with EUS but not in other imaging modalities. EUS-P was done in 7 other cases because there was minimal ascitic fluid and no safe window for percutaneous abdominal aspiration. Ascitic fluid was obtained in all cases by EUS-P. The average amount aspirated was 14.1 mL(range 0.5-38 mL) and that was sent for cytological exam. The etiology of ascitic fluid was benign in 5 patients and malignant in 6. In all cases, ascitic fluid was obtained with the first needle pass. No procedure-related adverse effects occurred.CONCLUSION: EUS-P with an automated springloaded needle device is a feasible and safe method for ascites evaluation.Rei Suzuki Atsushi Irisawa Manoop S Bhutani Takuto Hikichi Tadayuki Takagi Goro Shibukawa Ai Sato Masaki Sato Tsunehiko Ikeda Ko Watanabe Jun Nakamura Srinadh Annangi Kazuhiro Tasaki Katsutoshi Obara Hiromasa Ohira 2014World Journal of Gastrointestinal Endoscopy2014,6,2:3
6Cronkhite-Canada syndrome associated with myelodysplastic syndrome显示文摘We report a case of Cronkhite-Canada syndrome(CCS)associated with myelodysplastic syndrome(MDS).A 54-year-old woman,diagnosed as MDS the prior year after evaluation of anemia,visited our hospital with the chief complaint of epigastric discomfort.She also had dysgeusia,alopecia,atrophic nail change,and pigmentation of the palm,all of which began several months ago.Blood tests revealed severe hypoalbuminemia.Colonoscopy(CS)showed numerous,dense,red polyps throughout the colon and rectum.Biopsy specimens showed stromal edema,infi ltration of lymphocytes,and cystic dilatation of the crypt.Her clinical manifestations and histology were consistent with CCS.We prescribed corticosteroids,which dramatically improved her physical findings,laboratory data,and endoscopic fi ndings.This is the first report of CCS in a patient with MDS.Rei Suzuki Atsushi Irisawa Takuto Hikichi Yuta Takahashi Hiroko Kobayashi Hiromi Kumakawa Hiromasa Ohira 2009World Journal of Gastroenterology2009,15,46:3
7Predictive factors for the failure of endoscopic stent-instent self-expandable metallic stent placement to treat malignant hilar biliary obstruction显示文摘AIM To investigate the factors predictive of failure when placing a second biliary self-expandable metallic stents(SEMSs). METHODS This study evaluated 65 patients with an unresectable malignant hilar biliary obstruction who were examined in our hospital. Sixty-two of these patients were recruited to the study and divided into two groups: the success group, which consisted of patients in whom a stent-in-stent SEMS had been placed successfully, and the failure group, which consisted of patients in whom the stent-in-stent SEMS had not been placed successfully. We compared the characteristics of the patients, the stricture state of their biliary ducts, and the implemented endoscopic retrograde cholangiopancreatography(ERCP) procedures between the two groups.RESULTS The angle between the target biliary duct stricture and the first implanted SEMS was significantly larger in the failure group than in the success group. There were significantly fewer wire or dilation devices(ERCP catheter, dilator, or balloon catheter) passing the first SEMS cell in the failure group than in the success group. The cut-off value of the angle predicting stent-in-stent SEMS placement failure was 49.7 degrees according to the ROC curve(sensitivity 91.7%, specificity 61.2%). Furthermore, the angle was significantly smaller in patients with wire or dilation devices passing the first SEMS cell than in patients without wire or dilation devices passing the first SEMS cell. CONCLUSION A large angle was identified as a predictive factor for failure of stent-in-stent SEMS placement.Mitsuru Sugimoto Tadayuki Takagi Rei Suzuki Naoki Konno Hiroyuki Asama Ko Watanabe Jun Nakamura Hitomi Kikuchi Yuichi Waragai Mika Takasumi Yuki Sato Takuto Hikichi Hiromasa Ohira 2017World Journal of Gastroenterology2017,23,34:3
8Screening for hilar biliary invasion in ampullary cancer patients显示文摘BACKGROUND The treatment for ampullary cancer is pancreatoduodenectomy or local ampullectomy.However,effective methods for the preoperative investigation of hilar biliary invasion in ampullary cancer patients have not yet been identified.AIM To determine the necessity of and an appropriate method for investigating hilar biliary invasion of ampullary cancer.METHODS Among 43 ampullary cancer patients,34 underwent endoscopic treatment(n=9)or surgery(n=25).The use of imaging findings(thickening and enhancement of the bile duct wall on contrast-enhanced computed tomography,irregularity on endoscopic retrograde cholangiography,thickening of the entire bile duct wall on intraductal ultrasonography(IDUS),and partial thickening of the bile duct wall on IDUS)and biliary biopsy results for diagnosing hilar biliary invasion of ampullary cancer was compared.RESULTS Hilar invasion was not observed in every patient.Among the patients who did not undergo biliary stent insertion,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results showed the highest accuracy(100%)for diagnosing hilar biliary invasion.However,each imaging method and biliary biopsy yielded some false-positive results.CONCLUSION Although some false-positive results were obtained with each method,the combination of partial thickening of the bile duct wall on IDUS and biliary biopsy results was useful for diagnosing hilar biliary invasion of ampullary cancer.However,hilar invasion of ampullary cancer is rare;therefore,the investigation of hilar biliary invasion of ampullary cancer might be unnecessary.Tadayuki Takagi Mitsuru Sugimoto Rei Suzuki Naoki Konno Hiroyuki Asama Yuki Sato Hiroki Irie Jun Nakamura Mika Takasumi Minami Hashimoto Tsunetaka Kato Ryoichiro Kobashi Takumi Yanagita Yuko Hashimoto Shigeru Marubashi Takuto Hikichi Hiromasa Ohira 2022World Journal of Gastrointestinal Endoscopy2022,14,9:2
9Endoscopic therapy for esophageal hematoma with blue rubber bleb nevus syndrome显示文摘A 57-year-old woman previously diagnosed with blue rubber bleb nevus syndrome(BRBNS) reported hematemesis. BRBNS is a rare vascular anomaly syndrome consisting of multifocal hemangiomas of the skin and gastrointestinal(GI) tract but her GI tract had never been examined. An upper gastrointestinal endoscopy revealed a large bleeding esophageal hematoma positioned between the thoracic esophagus and the gastric cardia. An endoscopic injection of polidocanol was used to stop the hematoma from bleeding. The hematoma was incised using the injectionneedle to reduce the pressure within it. Finally, argon plasma coagulation(APC) was applied to the edge of the incision. The esophageal hematoma disappeared seven days later. Two months after the endoscopic the rapy, the eso phage alulcerhealed and the hemangioma did not relapse. This rare case of a large esophageal hematoma originating from a hemangioma with BRBNS was treated using a combination of endoscopic therapy with polidocanol injection, incision, and APC.Mika Takasumi Takuto Hikichi Tadayuki Takagi Masaki Sato Rei Suzuki Ko Watanabe Jun Nakamura Mitsuru Sugimoto Yuichi Waragai Hitomi Kikuchi Naoki Konno Hiroshi Watanabe Katsutoshi Obara Hiromasa Ohira 2014World Journal of Gastrointestinal Endoscopy2014,6,12:2
