| 1 | 早期胃癌内镜下切除日本指南的历史和未来展望显示文摘日本胃癌治疗指南首次发表于2001年,其目的是为了明确不同治疗方案的适应证,从而减少不同医疗机构间治疗方式的差异。随着病例的积累及内镜黏膜下剥离术(ESD)的发展,早期胃癌(EGC)内镜下切除(ER)的适应证和治愈性范围有所扩大,但是,仍有部分问题亟待解决。使用风险评分系统(eCura system)评估淋巴结转移(LNM)的情况,可能有助于确定不符合内镜切除标准的EGC患者的治疗方案。对于不符合内镜切除标准的EGC患者,即最新指南中的eCura C-2分期的患者,尽管他们的LNM风险较高,但对于很多患者来说,追加胃切除联合淋巴结清扫术仍然是过度的治疗。而保留功能的低侵入性手术,如内镜下非开放式胃壁反转切除术联合腹腔镜前哨淋巴结活检,有可能会解决该问题。此外,对于拒绝追加胃切除术的患者,可采取更多的低侵入性治疗方式,如ER联合化疗。 | Waku Hatta Takuji Gotoda Tomoyuki Koike Atsushi Masamune 丁士刚(译) 张冬雪(译) 乌雅罕(译) | 2020 | 中华胃肠内镜电子杂志2020，7，1： | 22 |
| 2 | Activation of JAK-STAT pathway is required for platelet-derived growth factor-induced proliferation of pancreatic stellate cells显示文摘AIM: To clarify the role of Janus kinase-signal transducersand activators of transcription (JAK-STAT) pathway in platelet-derived growth factor (PDGF) induced proliferation in activated pancreatic stellate cells (PSCs).METHODS: PSCs were isolated from rat pancreas tissue, and used in their culture-activated, myofibroblast-like phenotype. STAT-specific binding activity was assessed by electrophoretic mobility shift assay. Activation of Src, JAK2,STAT1, STAT3, and ERK was determined by Western blotting using anti-phosphospecific antibodies. Cell proliferation was assessed by measuring the incorporation of 5-bromo-2′deoxyuridine.RESULTS: PDGF-BB induced STAT-specific binding activity, and activation of Src, JAK2, STAT1, STAT3, and ERK. Ethanol and acetaldehyde at clinically relevant concentrations decreased basal activation of JAK2 and STAT3. PDGFinduced activation of STAT1 and STAT3 was inhibited bya Src inhibitor PP1 and a JAK2 inhibitor AG490, whereasPDGF-induced activation of ERK was inhibited by PP1, and not by AG490. PDGF-induced proliferation was inhibited by PP1 and AG490 as well as by STAT3 antisense oligonucleotide.CONCLUSION: PDGF-BB activated JAK2-STAT pathwayvia Src-dependent mechanism. Activation of JAK2-STAT3pathway, in addition to ERK, may play a role in PDGF-induced proliferation of PSCs. | Atsushi Masamune Masahiro Satoh Kazuhiro Kikuta Noriaki Suzuki Tooru Shimosegawa | 2005 | World Journal of Gastroenterology2005，11，22： | 15 |
| 3 | Real-time in situ three-dimensional integral videography and surgical navigation using augmented reality: a pilot study显示文摘To evaluate the feasibility and accuracy of a three-dimensional augmented reality system incorporating integral videography for imaging oral and maxillofacial regions, based on preoperative computed tomography data. Three-dimensional surface models of the jawbones, based on the computed tomography data, were used to create the integral videography images of a subject's maxillofacial area. The three-dimensional augmented reality system (integral videography display, computed tomography, a position tracker and a computer) was used to generate a three-dimensional overlay that was projected on the surgical site via a half-silvered mirror. Thereafter, a feasibility study was performed on a volunteer. The accuracy of this system was verified on a solid model while simulating bone resection. Positional registration was attained by identifying and tracking the patient/surgical instrument's position. Thus, integral videography images of jawbones, teeth and the surgical tool were superimposed in the correct position. Stereoscopic images viewed from various angles were accurately displayed. Change in the viewing angle did not negatively affect the surgeon's ability to simultaneously observe the three-dimensional images and the patient, without special glasses. The difference in three-dimensional position of each measuring point on the solid model and augmented reality navigation was almost negligible (<1 mm); this indicates that the system was highly accurate. This augmented reality system was highly accurate and effective for surgical navigation and for overlaying a three-dimensional computed tomography image on a patient's surgical area, enabling the surgeon to understand the positional relationship between the preoperative image and the actual surgical site, with the naked eye. | Hideyuki Suenaga Huy Hoang Tran Hongen Liao Ken Masamune Takeyoshi Dohi Kazuto Hoshi Yoshiyuki Mori Tsuyoshi Takato | 2013 | International Journal of Oral Science2013，5，2： | 11 |
| 4 | Endothelin-1 stimulates contraction and migration of rat pancreatic stellate cells显示文摘AIM: To examine the ability of ET-1 to affect the cell functions of PSCs and the underlying molecular mechanisms.METHODS: PSCs were isolated from the pancreas of male Wistar rats after perfusion with collagenase, and cells between passages two and five were used. Expression of ET-1 and ET receptors was assessed by reverse transcription-PCR and immunostaining. Phosphorylation of myosin regulatory light chain (MLC), extracellular-signal regulated kinase (ERK), and Akt was examined by Western blotting. Contraction of PSCs was assessed on hydrated collagen lattices. Cell migration was examined using modified Boyden chambers. Cell proliferation was assessed by measuring the incorporation of 5-bromo-2'-deoxyuridine.RESULTS: Culture-activated PSCs expressed ETA and ETB receptors, and ET-1. ET-1 induced phosphorylation of MLC and ERK, but not Akt. ET-1 induced contraction and migration,but did not alter proliferation of PSCs. ET-1-induced contraction was inhibited by an ETA receptor antagonist BQ-123 and an ETB receptor antagonist BQ-788, whereas migration was inhibited by BQ-788 but not by BQ-123. A Rho kinase inhibitor Y-27632 abolished both contraction and migration.CONCLUSION: ET-1 induced contraction and migration of PSCs through ET receptors and activation of Rho-Rho kinase. ETA and ETB receptors play different roles in the regulation of these cellular functions in response to ET-1. | Atsushi Masamune Masahiro Satoh Kazuhiro Kikuta Noriaki Suzuki Kennichi Satoh Tooru Shimosegawa | 2005 | World Journal of Gastroenterology2005，11，39： | 11 |
| 5 | Establishment and characterization of a rat pancreatic stellate cell line by spontaneous immortalization显示文摘AIM: Activated pancreatic stellate cells (PSCs) have been implicated in the pathogenesis of pancreatic fibrosis and inflammation. Primary PSCs can be subcultured only several times because of their limited growth potential. A continuous cell line may therefore be valuable in studying molecular mechanisms of these pancreatic disorders. The aim of this study was to establish a cell line of rat PSCs by spontaneous immortalization.METHODS: PSCs were isolated from the pancreas of male Wistar rats, and conventional subcultivation was performed repeatedly. Telomerase activity was measured using the telomere repeat amplification protocol. Activation of transcription factors was assessed by electrophoretic mobility shift assay.Activation of mitogen-activated protein (MAP) kinases was examined by Western blotting using anti-phosphospecific antibodies. Expression of cytokine-induced neutrophil chemoattractant-1 was determined by enzyme immunoassay.RESULTS: Conventional subcultivation yielded actively growing cells. One clone was obtained after limiting dilution,and designated as SIPS. This cell line has been passaged repeatedly more than 2 years, and is thus likely immortalized.SIPS cells retained morphological characteristics of primary,culture-activated PSCs. SIPS expressed α-smooth muscle actin, glial acidic fibrillary protein, vimentin, desmin, type Ⅰ collagen, fibronectin, and prolyl hydroxylases. Telomerase activity and p53 expression were negative. Proliferation of SIPS cells was serum-dependent, and stimulated with platelet-derived growth factor-BB through the activation of extracellular signal-regulated kinase. Interleukin-1β activated nuclear factor-κB, activator protein-1, and MAP kinases.Interleukin-1β induced cytokine-induced neutrophil chemoattractant-1 expression through the activation of nuclear factor-κB and MAP kinases.CONCLUSION: SIPS cells can be useful for in vitro studies of cell biology and signal transduction of PSCs. | Atsushi Masamune Masahiro Satoh Kazuhiro Kikuta Noriaki Suzuki Tooru Shimosegawa | 2003 | World Journal of Gastroenterology2003，9，12： | 11 |
| 6 | Management of acute pancreatitis in Japan: analysis of nationwide epidemiological survey显示文摘Acute pancreatitis(AP) is an acute inflammatory disease of the exocrine pancreas. In Japan, nationwide epidemiological surveys have been conducted every 4 to 5 years by the Research Committee of Intractable Pancreatic Diseases, under the support of the Ministry of Health, Labour, and Welfare of Japan. We reviewed the results of the nationwide surveys focusing on the severity assessment and changes in the therapeutic strategy for walled-off necrosis. The severity assessment system currently used in Japan consists of 9 prognostic factors and the imaging grade on contrastenhanced computed tomography. By univariate analysis, all of the 9 prognostic factors were associated with AP-related death. A multivariate analysis identified 4 out of the 9 prognostic factors(base excess or shock, renal failure, systemic inflammatory response syndrome criteria, and age) that were associated with AP-related death. Receiver-operating characteristics curve analysis showed that the area under the curve was 0.82 for these 4 prognostic factors and 0.84 for the 9 prognostic factors, suggesting the comparable utility of these 4 factors in the severity assessment. We also examined the temporal changes in treatment strategy for walled-off necrosis in Japan according to the 2003, 2007, and 2011 surveys. Step-up approaches and lessinvasive endoscopic therapies were uncommon in 2003 and 2007, but became popular in 2011. Mortality has been decreasing in patients who require intervention for walled-off necrosis. In conclusion, the nationwide survey revealed the comparable utility of 4 prognostic factors in the severity assessment and the increased use of less-invasive, step-up approaches with improved clinical outcomes in the management of walled-off necrosis. | Shin Hamada Atsushi Masamune Tooru Shimosegawa | 2016 | World Journal of Gastroenterology2016，22，28： | 10 |
| 7 | Micro RNA-320 family is downregulated in colorectal adenoma and affects tumor proliferation by targeting CDK6显示文摘AIM: To investigate the microR NA(miR NA) expression during histological progression from colorectal normal mucosa through adenoma to carcinoma within a lesion. METHODS: Using microarray, the sequential changes in miR NA expression profiles were compared in colonic lesions from matched samples; histologically, nonneoplastic mucosa, adenoma, and submucosal invasive carcinoma were microdissected from a tissue sample. Cell proliferation assay was performed to observe the effect of miR NA, and its target genes were predicted using bioinformatics approaches and the expression profile of SW480 transfected with the miR NA mimics. mR NA and protein levels of the target gene in colon cancer cell lines with a mimic control or miR NA mimics were measured using qR TPCR and Western blotting. The expression levels of miR NA and target gene in colorectal tissue samples were also measured.RESULTS: Microarray analysis identified that the miR-320 family, including miR-320 a, miR-320 b, miR-320 c, miR-320 d and miR-320 e, were differentially expressed in adenomaand submucosal invasive carcinoma. The mi R-320 family, which inhibits cell proliferation, is frequently downregulated in colorectal adenoma and submucosal invasive carcinoma tissues. Seven genes including CDK6 were identified to be common in the results of gene expression array and bioinformatics analyses performed to find the target gene of the miR-320 family. We confirmed that mR NA and protein levels of CDK6 were significantly suppressed in colon cancer cell lines with miR-320 family mimics. CDK6 expression was found to increase from non-neoplastic mucosa through adenoma to submucosal invasive carcinoma tissues and showed an inverse correlation with miR-320 family expression.CONCLUSION: MiR-320 family affects colorectal tumor proliferation by targeting CDK6, plays important role in its growth, and is considered to be a biomarker for its early detection. | Toshihiro Tadano Yoichi Kakuta Shin Hamada Yosuke Shimodaira Masatake Kuroha Yoko Kawakami Tomoya Kimura Hisashi Shiga Katsuya Endo Atsushi Masamune Seiichi Takahashi Yoshitaka Kinouchi Tooru Shimosegawa | 2016 | World Journal of Gastrointestinal Oncology2016，8，7： | 9 |
| 8 | Green tea polyphenol epigallocatechin-3-gallate blocks PDGF-induced proliferation and migration of rat pancreatic stellate cells显示文摘AIM: To clarify the effects of epigallocatechin-3-gallate (EGCG) on the platelet-derived growth factor (PDGF)-BBinduced proliferation and migration of pancreatic stellate cells (PSCs).METHODS: PSCs were isolated from rat pancreas tissue and used in their culture-activated, myofibroblast-like phenotype. Cell proliferation was assessed by measuring the incorporation of 5-bromo-2'-deoxyuridine. Cell migration was assessed using modified Boyden chambers. CyclinD1, p21waf1, and p27kip1 expression and phosphorylation of PDGF β-receptor, extracellular signal-regulated kinase, and Akt were examined by Western blotting. Activation of phosphatidylinositol 3-kinase was examined by kinase assay using phosphatidylinositol as a substrate. Cell cycle was assessed by flow cytometry after staining with propidium iodide. RESULTS: EGCG at non-cytotoxic concentrations inhibited PDGF-induced proliferation and migration. This effect was associated with the inhibition of cell cycle progression beyondthe G1 phase, decreased cyclin D1 and increased p27Kip1 expression. EGCG inhibited tyrosine phosphorylation of PDGF β-receptor and downstream activation of extracellular signal-regulated kinase and phosphatidylinositol 3-kinase/ Akt pathways.CONCLUSION: EGCG inhibited PDGF-BB-induced proliferation and migration of PSCs through the inhibrdon of PDGF-mediated signaling pathways. | Atsushi Masamune Kazuhiro Kikuta Masahiro Satoh Noriaki Suzuki Tooru Shimosegawa | 2005 | World Journal of Gastroenterology2005，11，22： | 8 |
| 9 | Usefulness of urinary trypsinogen-2 and trypsinogen activation peptide in acute pancreatitis:A multicenter study in Japan显示文摘BACKGROUND Rapid urinary trypsinogen-2 dipstick test and levels of urinary trypsinogen-2 and trypsinogen activation peptide(TAP) concentration have been reported as prognostic markers for the diagnosis of acute pancreatitis.AIM To reconfirm the validity of all these markers in the diagnosis of acute pancreatitis by undertaking a multi-center study in Japan.METHODS Patients with acute abdominal pain were recruited from 17 medical institutions in Japan from April 2009 to December 2012. Urinary and serum samples were collected twice, at enrollment and on the following day for measuring target markers. The diagnosis and severity assessment of acute pancreatitis were assessed based on prognostic factors and computed tomography(CT) Grade of the Japanese Ministry of Health, Labour, and Welfare criteria.RESULTS A total of 94 patients were enrolled during the study period. The trypsinogen-2 dipstick test was positive in 57 of 78 patients with acute pancreatitis(sensitivity,73.1%) and in 6 of 16 patients with abdominal pain but without any evidence of acute pancreatitis(specificity, 62.5%). The area under the curve(AUC) score of urinary trypsinogen-2 according to prognostic factors was 0.704, which was highest in all parameter. The AUC scores of urinary trypsinogen-2 and TAP according to CT Grade were 0.701 and 0.692, respectively, which shows higher than other pancreatic enzymes. The levels of urinary trypsinogen-2 and TAP were significantly higher in patients with extended extra-pancreatic inflammation as evaluated by CT Grade.CONCLUSION We reconfirmed urinary trypsinogen-2 dipstick test is useful as a marker for the diagnosis of acute pancreatitis. Urinary trypsinogen-2 and TAP may be considered as useful markers to determine extra-pancreatic inflammation in acute pancreatitis. | Hiroaki Yasuda Keisho Kataoka Yoshifumi Takeyama Kazunori Takeda Tetsuhide Ito Toshihiko Mayumi Shuji Isaji Tetsuya Mine Motoji Kitagawa Seiki Kiriyama Junichi Sakagami Atsushi Masamune Kazuo Inui Kenji Hirano Ryukichi Akashi Masamichi Yokoe Yoshio Sogame Kazuichi Okazaki Chie Morioka Yasuyuki Kihara Shigeyuki Kawa Masao Tanaka Akira Andoh Wataru Kimura Isao Nishimori Junji Furuse Isao Yokota Tooru Shimosegawa | 2019 | World Journal of Gastroenterology2019，25，1： | 7 |
| 10 | Transition of early-phase treatment for acute pancreatitis: An analysis of nationwide epidemiological survey显示文摘Treatment of acute pancreatitis(AP) is one of the critical challenges to the field of gastroenterology because of its high mortality rate and high medical costs associated with the treatment of severe cases. Early-phase treatments for AP have been optimized in Japan, and clinical guidelines have been provided. However, changes in early-phase treatments and the relationship between treatment strategy and clinical outcome remain unclear. Retrospective analysis of nationwide epidemiological data shows that time for AP diagnosis has shortened, and the amount of initial fluid resuscitation has increased over time, indicating the compliance with guidelines. In contrast, prophylactic use of broad-spectrum antibiotics has emerged. Despite the potential benefits of early enteral nutrition, its use is still limited. The roles of continuous regional arterial infusion in the improvement of prognosis and the prevention of late complications are uncertain. Furthermore, early-phase treatments have had little impact on late-phase complications, such as walledoff necrosis, surgery requirements and late(> 4 w) AP-related death. Based on these observations, earlyphase treatments for AP in Japan have approached the optimal level, but late-phase complications have become concerning issues. Early-phase treatments and the therapeutic strategy for late-phase complications both need to be optimized based on firm clinical evidence and cost-effectiveness. | Shin Hamada Atsushi Masamune Tooru Shimosegawa | 2017 | World Journal of Gastroenterology2017，23，16： | 6 |
| 11 | Impaired glucose tolerance in acute pancreatitis显示文摘Acute pancreatitis(AP) is an acute inflammatory disease of the exocrine pancreas. In spite of the pivotal role of the endocrine pancreas in glucose metabolism, the impact of impaired glucose tolerance on AP has not been fully elucidated. A meta-analysis of seven observational studies showed that type 2 diabetes mellitus(DM) was associated with an increased risk of AP. The increased risk of AP shown in the meta-analysis was independent of hyperlipidemia, alcohol use and gallstones. Antidiabetic drugs including incretins might increase the risk of AP, but no intervention trials have confirmed this. Although a controversial finding, DM seems to be associated with severe attacks and organ failure in AP. We analyzed the results of a nationwide epidemiological survey of AP in Japan. We studied the impact of pre-existing DM on the clinical course of AP in 1954 cases for which information on DM status was available at the onset of AP. The prevalence of DM in AP patients(12.8%) was higher than that in the general population in Japan(10.5%). AP patients with DM had higher morbidity of cardiovascular and renal failure than those without DM. About 35% of the idiopathic AP patients with DM had renal failure. The mortality of AP patients with DM(4.0%) was higher than that of AP patients without DM(1.7%). If stratified by etiology, idiopathic, but not alcoholic or biliary, AP patients with DM were predisposed to increased mortality(9.7%). In conclusion, impaired glucose tolerance might have an impact on the development and clinical outcome of AP. However, the impact might depend on the cause of hyperglycemia, the condition of DM including severity, duration and treatment, and the characteristics of the AP patients including age, etiology and comorbidity. | Kazuhiro Kikuta Atsushi Masamune Tooru Shimosegawa | 2015 | World Journal of Gastroenterology2015，21，24： | 6 |
| 12 | Granular cell tumor of the pancreas:A case report and review of literature显示文摘Granular cell tumors,also called Abrikossof's tumors,were originally described by Abrikossof A in 1926.The f irst case of a pancreatic granular cell tumor was described in 1975 and only 6 cases have been reported.We describe a case of granular cell tumor in the pancreas showing pancreatic duct obstruction.Because imaging studies showed f indings compatible with those of pancreatic carcinoma,the patient underwent distal pancreatectomy.Histological examination showed that the tumor consisted of a nested growth of large tumor cells with ample granular cytoplasm and small round nuclei.The tumor cells expressed S-100 protein and were stained with neuron-specific enolase and periodic acid-Schiff,but were negative for desmin,vimentin,and cytokeratin.The resected tumor was diagnosed as a granular cell tumor.To our knowledge,this is the seventh case of Granular cell tumor of the pancreas to be reported. | Atsushi Kanno Kennichi Satoh Morihisa Hirota Shin Hamada Jun Umino Hiromichi Itoh Atsushi Masamune Shinichi Egawa Fuyuhiko Motoi Michiaki Unno Kazuyuki Ishida Tooru Shimosegawa | 2010 | World Journal of Gastrointestinal Oncology2010，2，2： | 5 |
| 13 | MSX2 overexpression inhibits gemcitabine-induced caspase-3 activity in pancreatic cancer cells显示文摘AIM: To evaluate the effect of MSX2 on gemcitabineinduced caspase-3 activation in pancreatic cancer cell line Panc-1.METHODS: Using V5-tagged MSX2 expression vector,stable transfectant of MSX2 was generated from Panc-1cells (Px14 cells). Cell viability under gemcitabine administration was determined by MTT assay relative to control cell line (empty-vector transfected Panc-1 cells;P-3EV cells). Hoechst staining was used for the detection of apoptotic cell. Activation of caspase-3 was assessed using Western blotting analysis and direct measurement of caspase-3 specific activities.RESULTS: MSX2 overexpression in Panc-1 cells resulted in decreased gemcitabine-induced caspase-3 activation and increased cell viability under gemcitabine treatment in Px14 cells.CONCLUSION: MSX2 exerts repressive effects on gemcitabine-induced apoptotic pathway. This novel apoptosis-regulating function of MSX2 may provide a new therapeutic target for pancreatic cancer. | Shin Hamada Kennichi Satoh Kenji Kimura Atsushi Kanno Atsushi Masamune Tooru Shimosegawa | 2005 | World Journal of Gastroenterology2005，11，43： | 4 |
| 14 | IgG4-unrelated type 1 autoimmune pancreatitis显示文摘A 50-year-old male was referred to our hospital for the evaluation of hyperproteinemia.Fluorodeoxyglucose positron emission tomography revealed high fluorodeoxyglucose uptake in the pancreas,bilateral lacrimal glands,submandibular glands,parotid glands,bilateral pulmonary hilar lymph nodes,and kidneys.Laboratory data showed an elevation of hepatobiliary enzymes,renal dysfunction,and remarkably high immunoglobulin(Ig) G levels,without elevated serum IgG4.Abdominal computed tomography revealed swelling of the pancreatic head and bilateral kidneys.Endoscopic retrograde cholangiopancreatography showed an irregular narrowing of the main pancreatic duct in the pancreatic head and stricture of the lower common bile duct.Histological examination by endoscopic ultrasonography-guided fine-needle aspiration revealed findings of lymphoplasmacytic sclerosing pancreatitis without IgG4-positive plasma cells.Abnormal laboratory values and the swelling of several organs were improved by the treatment with steroids.The patient was diagnosed as having type 1 autoimmune pancreatitis(AIP) based on the International Consensus Diagnostic Criteria.Therefore,we encountered a case of compatible type 1 AIP without elevated levels of serum IgG4 or IgG4-positive plasma cells.This case suggests that AIP phenotypes are not always associated with IgG4. | Eriko Nakano Atsushi Kanno Atsushi Masamune Naoki Yoshida Seiji Hongo Shin Miura Tetsuya Takikawa Shin Hamada Kiyoshi Kume Kazuhiro Kikuta Morihisa Hirota Keisuke Nakayama Fumiyoshi Fujishima Tooru Shimosegawa | 2015 | World Journal of Gastroenterology2015，21，33： | 3 |
| 15 | Pancreatic duct drainage using EUS-guided rendezvous technique for stenotic pancreaticojejunostomy显示文摘The patient was a 30-year-old female who had undergone excision of the extrahepatic bile duct and Rouxen-Y hepaticojejunostomy for congenital biliary dilatation at the age of 7.Thereafter,she suffered from recurrent acute pancreatitis due to pancreaticobiliary maljunction and received subtotal stomach-preserving pancreaticoduodenectomy.She developed a pancreatic fistula and an intra-abdominal abscess after the operation.These complications were improved by percutaneous abscess drainage and antibiotic therapy.How ever,upper abdominal discomfort and the elevation of serum pancreatic enzymes persisted due to stenosis from the pancreaticojejunostomy.Because we could not accomplish dilation of the stenosis by endoscopic retrograde cholangiopancreatography,we tried an endoscopic ultrasonography(EUS) guided rendezvous technique for pancreatic duct drainage.After transgastric puncture of the pancreatic duct using an EUS-fine needle aspiration needle,the guidewire was inserted into the pancreatic duct and finally reached to the jejunum through the stenotic anastomosis.We changed the echoendoscope to an oblique-viewing endoscope,then grasped the guidewire and withdrew it through the scope.The stenosis of the pancreaticojejunostomy was dilated up to 4 mm,and a pancreatic stent was put in place.Though the pancreatic stent was removed after three months,the patient remained symptomfree.Pancreatic duct drainage using an EUS-guided rendezvous technique was useful for the treatment of a stenotic pancreaticojejunostomy after pancreaticoduodenectomy. | Tetsuya Takikawa Atsushi Kanno Atsushi Masamune Shin Hamada Eriko Nakano Shin Miura Hiroyuki Ariga Jun Unno Kiyoshi Kume Kazuhiro Kikuta Morihisa Hirota Hiroshi Yoshida Yu Katayose Michiaki Unno Tooru Shimosegawa | 2013 | World Journal of Gastroenterology2013，19，31： | 3 |
