| 1 | Prognosis of metastatic splenic hilum lymph node in patients with gastric cancer after total gastrectomy and splenectomy显示文摘AIM:To clarify the significance of combined resection of the spleen to dissect the No.10 lymph node(LN). METHODS:We studied 191 patients who had undergone total gastrectomy with splenectomy,excluding non-curative cases,resection of multiple gastric cancer, and those with remnant stomach cancer.Various clinico-pathological factors were evaluated for any independent contributions to No.10 LN metastasis,usingχ 2 test. Significant factors were extracted for further analysis, carried out using a logistic regression method.Furthermore,lymph node metastasis was evaluated for any independent contribution to No.10 LN metastasis,using the same methods.The cumulative survival rate was calculated using the Kaplan-Meier method.The significance of any difference between the survival curves was determined using the Cox-Mantel test,and any difference was considered significant at the 5%level. RESULTS:From the variables considered to be potentially associated with No.10 LN metastasis,age, depth,invasion of lymph vessel,N factor,the numberof lymph node metastasis,Stage,the number of sites, and location were found to differ significantly between those with metastasis(the Positive Group)and those without(the Negative Group).A logistic regression analysis showed that the localization and Stage were significant parameters for No.10 LN metastasis.There was no case located on the lesser curvature in the Posi-tive Group.The numbers of No.2,No.3,No.4sa,No. 4sb,No.4d,No.7,and No.11 LN metastasis were each found to differ significantly between the Positive Group and the Negative Group.A logistic regression analysis showed that No.4sa,No.4sb,and No.11 LN metastasis were each a significant parameter for No.10 LN metastasis.There was no significant difference in survival curves between the Positive Group and the Negative Group. CONCLUSION:Splenectomy should be performed to dissect No.10 LN for cases which have No.4sa,No. 4sb or No.11 LN metastasis.However,in cases where the tumor is located on the lesser curvature,splenectomy can be omitted. | Keishiro Aoyagi Kikuo Kouhuji Motoshi Miyagi Takuya Imaizumi Junya Kizaki Kazuo Shirouzu | 2010 | World Journal of Hepatology2010，2，2： | 26 |
| 2 | Single-cell RNA-seq highlights intra-tumoral heterogeneity and malignant progression in pancreatic ductal adenocarcinoma显示文摘Pancreatic ductal adenocarcinoma (PDAC) is the most common type of pancreatic cancer featured with high intra-tumoral heterogeneity and poor prognosis. To comprehensively delineate the PDAC intra-tumoral heterogeneity and the underlying mechanism for PDAC progression, we employed single-cell RNA-seq (scRNA-seq) to acquire the transcriptomic atlas of 57,530 individual pancreatic cells from primary PDAC tumors and control pancreases, and identified diverse malignant and stromal cell types, including two ductal subtypes with abnormal and malignant gene expression profiles respectively, in PDAC. We found that the heterogenous malignant subtype was composed of several subpopulations with differential proliferative and migratory potentials. Cell trajectory analysis revealed that components of multiple tumor-related pathways and transcription factors (TFs) were differentially expressed along PDAC progression. Furthermore, we found a subset of ductal cells with unique proliferative features were associated with an inactivation state in tumor-infiltrating T cells, providing novel markers for the prediction of antitumor immune response. Together, our findings provide a valuable resource for deciphering the intra-tumoral heterogeneity in PDAC and uncover a connection between tumor intrinsic transcriptional state and T cell activation, suggesting potential biomarkers for anticancer treatment such as targeted therapy and immunotherapy. | Junya Peng Bao-Fa Sun Chuan-Yuan Chen Jia-Yi Zhou Yu-Sheng Chen Hao Chen Lulu Liu Dan Huang Jialin Jiang Guan-Shen Cui Ying Yang Wenze Wang Dan Guo Menghua Dai Junchao Guo Taiping Zhang Quan Liao Yi Liu Yong-Liang Zhao Da-Li Han Yupei Zhao Yun-Gui Yang Wenming Wu | 2019 | Cell Research2019，29，9： | 24 |

| 4 | Characteristics and prognosis of synchronous multiple early gastric cancer显示文摘AIM:To assess the clinicopathologic characteristics,risk factors,and prognosis for synchronous multiple early gastric cancer(SMGC).METHODS:A total of 146 patients with SMGC and1194 patients with single gastric cancer who had undergone gastrectomy between 1989 and 2008 were retrospectively analyzed to determine their clinicopathologic characteristics and postoperative survival.Tumors were classified into groups on the basis of location and histology.Smoking habits were evaluated using the Brinkman index.Clinical and pathological factors were compared using either Fisher’s exact test or Pearson’sχ2test.Logistic regression analysis was performed to identify independent risk factors.Survival rate was calculated using the Kaplan-Meier method.RESULTS:SMGCs accounted for 10.9%of gastric cancer cases and occurred predominantly in elderly male patients with a family history of gastric cancer who were both smokers and drinkers.These tumors were typically macroscopically elevated and histologically differentiated.There were no significant differences between SMGC and single gastric cancer patients with respect to tumor location,tumor size,lymph node metastasis,the number of metastatic lymph nodes,venous invasion,or tumor stage(P=0.052,P=0.347,P=0.595,P=0.805,P=0.559,and P=0.408,respectively).Further,there was no significant difference in postoperative survival between the patient groups(P=0.200).Of the 146SMGC patients,a single patient had remnant cancer.CONCLUSION:A careful preoperative endoscopy is necessary for patients who are at high risk of SMGC,and minimally invasive treatment may be indicated in some cases. | Taro Isobe Kousuke Hashimoto Junya Kizaki Naotaka Murakami Keishiro Aoyagi Kikuo Koufuji Yoshito Akagi Kazuo Shirouzu | 2013 | World Journal of Gastroenterology2013，19，41： | 17 |
| 5 | Effects of heat treatments on microstructure and mechanical properties of Mg-15Gd-5Y-0.5Zr alloy显示文摘Microstructure and mechanical properties of Mg-15wt.%Gd-5 wt.%Y-0.5wt.% Zr alloy were investigated in a series of conditions. The eutectic was dissolved into the matrix and there was no evident grain growth after solutionized at 525 °C for 12 h. The evolution of the phase constituents from as-cast to cast-T4 was as follows: α-Mg solid solution+Mg5(Gd,Y) eutectic compound→α-Mg solid solution+ spheroidized Mg5(Gd, Y) phase→α-Mg supersaturated solid solution+cuboid-shaped compound (Mg2Y3Gd2). And the precipitation se- quences of Mg-15Gd-5Y-0.5Zr alloy were observed, according to the hardness response to isothermal ageing at 225-300 °C for 0-128 h. | 高岩 王渠东 顾金海 赵阳 童炎 Junya Kaneda | 2008 | Journal of Rare Earths2008，26，2： | 16 |
| 6 | Investigation and prediction of enteral nutrition problems after percutaneous endoscopic gastrostomy显示文摘AIM:To investigate and predict enteral nutrition problems after percutaneous endoscopic gastrostomy (PEG). METHODS:We retrospectively analyzed data for 252 out of 285 patients who underwent PEG at our hospital from 1999 to 2008.Enteral nutrition problems after PEG were defined as:(1)patients who required ≥1 mo after surgery to switch to complete enteral nutrition,or who required additional parenteral alimentation continuously;or(2)patients who abandoned switching to enteral nutrition using the gastrostoma and employed other nutritional methods. We attempted to identify the predictors of problem cases by using a logistic regression analysis that examined the patients’backgrounds and the specific causes that led to their problems. RESULTS:Mean age of the patients was 75 years,and in general,their body weight was low and their overall condition was markedly poor.Blood testing revealed that patients tended to be anemic and malnourished.A total of 44 patients(17.5%)were diagnosed as having enteral nutrition problems after PEG.Major causes ofthe problems included pneumonia,acute enterocolitis (often Clostridium difficile-related),paralytic ileus and biliary tract infection.A multivariate analysis identified the following independent predictors for problem cases:(1)enteral nutrition before gastrectomy(a risk reduction factor);(2)presence of esophageal hiatal hernia;(3)past history of paralytic ileus;and(4) presence of chronic renal dysfunction. CONCLUSION:Enteral nutrition problems after PEG occurred at a comparatively high rate.Patient background analysis elucidated four predictive factors for the problem cases. | Shiro Yokohama Masaru Aoshima Yukiomi Nakade Junya Shindo Junichi Maruyama Masashi Yoneda | 2009 | World Journal of Gastroenterology2009，15，11： | 14 |

| 8 | Molecular targeting therapy using bevacizumab for peritoneal metastasis from gastric cancer显示文摘AIM: To clarify the significance of vascular endothelial growth factor(VEGF) in peritoneal metastasis from gastric cancer, using the gastric cancer cell line MKN-45 compared with the high potential peritoneal dissemination gastric cancer cell line MKN-45 P. METHODS: The supernatant of culture medium of MKN-45 cells or MKN-45 P cells was collected and the concentrations were measured of various cytokines, matrix metalloproteinases, growth factor and angiogenic factors, including VEGF. We performed an initial pilot study to explore whether bevacizumab, a humanized monoclonal antibody against VEGF, had any suppressive effect on the peritoneal dissemination from gastric cancer in an experimental nude mouse modelof peritoneal metastasis. RESULTS: The concentrations of interleukin-6(IL-6), IL-8, VEGF and matrix metalloproteinase-2 protein in the culture supernatant were each significantly higher than each of those for MKN-45. In the in vivo study, the volume of ascites and the mitotic index were significantly lower in the therapy group than in the nontherapy group. The survival curve of the therapy group was significantly higher than that of the non-therapy group. These results suggested that VEGF was correlated with peritoneal metastasis from gastric cancer. CONCLUSION: Findings suggested that bevacizumab for inhibiting VEGF could suppress peritoneal dissemination from gastric cancer. | Keishiro Aoyagi Kikuo Kouhuji Motoshi Miyagi Junya Kizaki Taro Isobe Kousuke Hashimoto Kazuo Shirouzu | 2013 | World Journal of Critical Care Medicine2013，2，4： | 12 |

| 10 | Acute appendicitis following endoscopic mucosal resection of cecal adenoma显示文摘Endoscopic mucosal resection(EMR) allows the removal of flat or sessile lesions, laterally spreading tumors, and carcinoma of the colon or the rectum limited to the mucosa or the superficial submucosa. Acute appendicitis is the most common abdominal emergency requiring emergency surgery, and it is also a rare complication of diagnostic colonoscopy and therapeutic endoscopy, including EMR. In the case presented here, a 53-year-old female underwent colonoscopy due to a positive fecal occult blood test and was diagnosed with cecal adenoma. She was referred to our hospital and admitted for treatment. The patient had no other symptoms. EMR was performed, and 7 h after the surgery, the patient experienced right-lower abdominal pain. Laboratory tests performed the following day revealed a WBC count of 16000/mm3, a neutrophil count of 14144/mm3, and a C-reactive protein level of 2.20 mg/d L, indicating an inflammatory response. Computed tomography also revealed appendiceal wall thickening and swelling, so acute appendicitis following EMR was diagnosed. Antibiotics were initiated leading to total resolution of the symptoms, and the patient was discharged on the sixth post-operative day. Pathological analysis revealed a high-grade cecal tubular adenoma. Such acute appendicitis following EMR is extremely rare, and EMR of the cecum may be a rare cause of acute appendicitis. | Yukako Nemoto Junya Tokuhisa Nagasato Shimada Tatsuya Gomi Iruru Maetani | 2015 | World Journal of Gastroenterology2015，21，27： | 9 |

| 12 | Impact of organic interlayer anions on the CO2 adsorption performance of Mg-Al layered double hydroxides derived mixed oxides显示文摘Herein we report a systematical investigation on the promoting effect of the carbon chain length of the intercalated carboxylic anions on the CO_2 capture performance of Mg-Al layer double hydroxides(LDHs).A series of organo-LDHs were successfully synthesized via co-precipitation and calcination-rehydration methods. All as-prepared samples were characterized by many techniques including XRD, ATR-FTIR, BET,and TGA. The XRD and ATR-FTIR studies indicated that organic anions were successfully intercalated into LDHs. The influence of some important parameters such as calcination temperature, adsorption temperature, and coating with(Li-Na-K)NO_3 molten salt was investigated. The results exhibited that when the number of carbon is greater than 10, the CO_2 capture capacity steadily increased with the increase in carbon number. After coating with 55 mol%(Li-Na-K)NO_3 molten salt, the CO_2 uptake of LDH-C16 sample with high Mg/Al ratios can be increased up to 3.25 mmol/g. The CO_2 adsorption/desorption cycling stability was also studied using temperature swing adsorption, which showed a stable CO_2 capture performance even after 22 cycles. Considering its high CO_2 capture capacity and good cycling stability, this novel CO_2 adsorbent is very promising in the sorption-enhanced water gas shift(SEWGS) processes. | Qingqing Qin Junya Wang Tuantuan Zhou Qianwen Zheng Liang Huang Yu Zhang Peng Lu Ahmad Umar Benoit Louis Qiang Wang | 2017 | Journal of Energy Chemistry2017，26，3： | 8 |
| 13 | Friction and wear behaviors of MoS2-multi-walled-carbonnanotube hybrid reinforced polyurethane composite coating显示文摘MoS2-multi-walled-carbon-nanotube(MWCNT)hybrids containing two-dimensional MoS2 and one-dimensional MWCNTs were synthesized through a one-step hydrothermal reaction.X-ray-diffraction and transmission-electron-microscopy results demonstrated that MoS2 nanosheets were successfully synthesized,and uniformly anchored on the MWCNTs’surfaces.Furthermore,the effects of the Mo S2-MWCNT hybrids on the tribological performances of polyurethane composite coatings were investigated using a UMT-2MT tribo-tester.Friction and wear test results revealed that the friction coefficient and wear rate of a 3 wt%Mo S2-MWCNT-1 filled polyurethane composite coating were reduced by 25.6% and 65.5%,respectively.The outstanding tribological performance of the MoS2-MWCNT-1 reinforced polyurethane composite coating was attributed to the excellent load-carrying capacity of the MWCNTs and good lubricant ability of MoS2.The surface morphologies of the worn surfaces and counterpart ball surfaces were investigated to reveal the wear mechanisms. | Zhaozhu ZHANG Mingming YANG Junya YUAN Fang GUO Xuehu MEN | 2019 | Friction2019，7，4： | 7 |
| 14 | Improved techniques for double-balloon-enteroscopy-assisted endoscopic retrograde cholangiopancreatography显示文摘AIM: To investigate the clinical outcome of double balloon enteroscopy (DBE)-assisted endoscopic retrograde cholangiopancreatography (DB-ERCP) in patients with altered gastrointestinal anatomy. METHODS: Between September 2006 and April 2011, 47 procedures of DB-ERCP were performed in 28 patients with a Roux-en-Y total gastrectomy (n = 11), Billroth Ⅱ gastrectomy (n = 15), or Roux-en-Y anastomosis with hepaticojejunostomy (n = 2). DB-ERCP was performed using a short-type DBE combined with several technical innovations such as using an endoscope attachment, marking by submucosal tattooing,selectively applying contrast medium, and CO2 insufflations. RESULTS: The papilla of Vater or hepaticojejunostomy site was reached in its entirety with a 96% success rate (45/47 procedures). There were no significant differences in the success rate of reaching the blind end with a DBE among Roux-en-Y total gastrectomy (96%), Billroth Ⅱ reconstruction (94%), or pancreatoduodenectomy (100%), respectively (P = 0.91). The total successful rate of cannulation and contrast enhancement of the target bile duct in patients whom the blind end was reached with a DBE was 40/45 procedures (89%). Again, there were no significant differences in the success rate of cannulation and contrast enhancement of the target bile duct with a DBE among Roux-en-Y total gastrectomy (88 %), Billroth Ⅱ reconstruction (89%), or pancreatoduodenectomy (100%), respectively (P = 0.67). Treatment was achieved in all 40 procedures (100%) in patients whom the contrast enhancement of the bile duct was successful. Common endoscopic treatments were endoscopic biliary drainage (24 procedures) and extraction of stones (14 procedures). Biliary drainage was done by placement of plastic stents. Stones extraction was done by lithotomy with the mechanical lithotripter followed by extraction with a basket or by the balloon pull-through method. Endoscopic sphincterotomy was performed in 14 procedures with a needle precutting knife using a guidewire. The mean total duration of the procedure was 93.6 ± 6.8 min and the mean time required to reach the papilla was 30.5 ± 3.7 min. The mean time required to reach the papilla tended to be shorter in Billroth Ⅱ reconstruction (20.9 ± 5.8 min) than that in Roux-en-Y total gastrectomy (37.1 ± 4.9 min) but there was no significant difference (P = 0.09). A major complication occurred in one patient (3.5%); perforation of the long limb in a patient with Billroth Ⅱ anastomosis.CONCLUSION: Short-type DBE combined with several technical innovations enabled us to perform ERCP in most patients with altered gastrointestinal anatomy. | Takashi Osoegawa Yasuaki Motomura Kazuya Akahoshi Naomi Higuchi Yoshimasa Tanaka Terumasa Hisano Souichi Itaba Junya Gibo Mariko Yamada Masaru Kubokawa Yorinobu Sumida Hirotada Akiho Eikichi Ihara Kazuhiko Nakamura | 2012 | World Journal of Gastroenterology2012，18，46： | 7 |
| 15 | Atg5 regulates late endosome and lysosome biogenesis显示文摘Autophagy is an evolutionarily conserved lysosome-based degradation process.Atg5 plays a very important role in autophagosome formation.Here we show that Atg5 is required for biogenesis of late endosomes and lysosomes in an autophagy-independent manner.In Atg5 cells,but not in other essential autophagy genes defecting cells,recycling and retrieval of late endosomal components from hybrid organelles are impaired,causing persistent hybrid organelles and defective formation of late endosomes and lysosomes.Defective retrieval of late endosomal components from hybrid organelles resulting from impaired recruitment of a component of V1-ATPase to acidic organelles blocks the pH-dependent retrieval of late endosomal components from hybrid organelles.Lowering the intracellular pH restores late endosome/lysosome biogenesis in Atg5 cells.Our data demonstrate an unexpected role of Atg5 and shed new light on late endosome and lysosome biogenesis. | PENG JunYa ZHANG Ran CUI YiTong LIU HaoDong ZHAO XiaoXin HUANG Lei HU MingXu YUAN XiaoXi MA BenYu MA XiaoWei TAKASHI Ueno MASAAKI Komatsu LIANG XingJie YU Li | 2014 | Science China(Life Sciences)2014，57，1： | 6 |
| 16 | Influence of heating rate on reactivity and surface chemistry of chars derived from pyrolysis of two Chinese low rank coals显示文摘A series of char samples were derived from pyrolysis of two typical low-rank coals in China(Shengli lignite and Shenmu bituminous coal) at low, medium and fast heating rates, respectively, to the same pyrolysis temperature 750 °C. Then these chars were characterized by means of thermogravimetric analysis and Fourier transform infrared spectrometer with the aim to investigate the influence of heating rate in pyrolysis process on gasification reactivity and surface chemistry of them. Besides, a homogeneous model was used to quantitatively analyze the activation energy of gasification reaction. The results reveal that Shengli lignite and its derived chars behave higher gasification reactivity and have less content of oxygen functional groups than Shenmu coal and chars. Meanwhile, chars derived from Shengli lignite at 50 °C/min and Shenmu coal at 200 °C/min have the greatest gasification reactivity, respectively. The oxygen functional groups in Shengli lignite are easily thermo-decomposed, and they are less affected by the heating rate, while that in Shenmu coal have a significant change with the variation of heating rate.In addition, there is no good correlation between the change of oxygen functional groups and that of the gasification reactivity of the derived chars from pyrolysis at different heating rates. | Liang Dingcheng Xie Qiang Li Guangsheng Cao Junya Zhang Jun | 2018 | International Journal of Mining Science and Technology2018，28，4： | 6 |
| 17 | Is endoscopic papillary large balloon dilatation without endoscopic sphincterotomy effective?显示文摘AIM: To evaluate the safety and efficacy of endoscopic papillary large balloon dilatation(EPLBD) without endoscopic sphincterotomy in a prospective study.METHODS: From July 2011 to August 2013, we performed EPLBD on 41 patients with nae papillae prospectively. For sphincteroplasty of EPLBD,endoscopic sphincterotomy(EST) was not performed,and balloon diameter selection was based on the distal common bile duct diameter. The balloon was inflated to the desired pressure. If the balloon waist did not disappear, and the desired pressure was satisfied, we judged the dilatation as complete. We used a retrieval balloon catheter or mechanical lithotripter(ML) to remove stones and assessed the rates of complete stone removal, number of sessions, use of ML and adverse events. Furthermore, we compared the presence or absence of balloon waist disappearance with clinical characteristics and endoscopic outcome.RESULTS: The mean diameters of the distal and maximum common bile duct were 13.5 ± 2.4 mm and16.4 ± 3.1 mm, respectively. The mean maximum transverse-diameter of the stones was 13.4 ± 3.4mm, and the mean number of stones was 3.0 ± 2.4.Complete stone removal was achieved in 97.5%(40/41)of cases, and ML was used in 12.2%(5/41) of cases.The mean number of sessions required was 1.2 ± 0.62.Pancreatitis developed in two patients and perforation in one. The rate of balloon waist disappearance was73.1%(30/41). No significant differences were noted in procedure time, rate of complete stone removal(100% vs 100%), number of sessions(1.1 vs 1.3, P= 0.22), application of ML(13% vs 9%, P = 0.71),or occurrence of pancreatitis(3.3% vs 9.1%, P =0.45) between cases with and without balloon waist disappearance.CONCLUSION: EST before sphincteroplasty may be unnecessary in EPLBD. Further investigations are needed to verify the relationship between the presence or absence of balloon waist disappearance. | Shigefumi Omuta Iruru Maetani Michihiro Saito Hiroaki Shigoka Katsushige Gon Junya Tokuhisa Mieko Naruki | 2015 | World Journal of Gastroenterology2015，21，23： | 5 |
| 18 | Effects of chlortetracycline,Cu and their combination on the performance and microbial community dynamics in swine manure anaerobic digestion显示文摘Swine manure was typical for the combined pollution of heavy metals and antibiotics. The effects of widely used veterinary antibiotic chlortetracycline(CTC), Cu and their combination on swine manure anaerobic digestion performance and microbial community have never been investigated. Thus, four 2 L anaerobic digestion reactors were established including reactor A(control), B(CTC spiked by 0.5 g/kg dry weight, dw), C(Cu spiked by 5 g/kg dw) and D(combination of CTC, 0.5 g/kg dw, and Cu, 5 g/kg dw), and dynamics of bacterial and archaeal community structure was investigated using high throughput sequencing method. Results showed that addition of CTC and Cu separately could increase the total biogas production by21.6% and 15.8%, respectively, while combination of CTC and Cu severely inhibited anaerobic digestion(by 30.3%). Furthermore, corresponding to different stages and reactors, four kinds of microbes including bacteria and archaea were described in detail, and the effects of CTC, Cu and their combination mainly occurred at hydrolysis and acidification phases. The addition of Cu alone changed the dynamics of archaeal community significantly. It was genus Methanomassiliicoccus that dominated at the active methane production for A, B and D, while it was genus Methanobrevibacter and Methanoculleus for C. | Rui Wang Junya Zhang Jibao Liu Dawei Yu Hui Zhong Yawei Wang Meixue Chen Juan Tong Yuansong Wei | 2018 | Journal of Environmental Sciences2018，30，5： | 5 |
| 19 | Molecular targeting to treat gastric cancer显示文摘Trastuzumab that targets human epidermal growth factor receptor 2(HER2) protein is the only approved molecular targeting agent for treating gastric cancer in Japan and the outcomes have been favorable. However,trastuzumab is effective for only 10% to 20% of the population with gastric cancer that expresses HER2 protein. Molecular targeting therapy with bevacizumab against vascular endothelial growth factors(VEGF) and with cetuximab and panitumumab against the epidermal growth factors pathway that have been approved for treating colorectal cancer are not considered effective for treating gastric cancer according to several clinical trials. However,ramucirumab that targets VEGF receptor-2 prolonged overall survival in a large phase Ⅲ clinical trial and it might be an effective molecular targeting therapy for gastric cancer. The significance of molecular targeting therapy for gastric cancer remains controversial. A large-scale randomized clinical trial of novel molecular targeting agents with which to treat gastric cancer is needed. | Keishiro Aoyagi Kikuo Kouhuji Junya Kizaki Taro Isobe Kousuke Hashimoto Kazuo Shirouzu | 2014 | World Journal of Gastroenterology2014，20，38： | 5 |
| 20 | Immediate detection of endoscopic retrograde cholangiopancreatographyrelated periampullary perforation: Fluoroscopy or endoscopy?显示文摘AIM:To investigate the causes and intraoperative detection of endoscopic retrograde cholangiopancreatography(ERCP)-related perforations to support immediate or early diagnosis.METHODS:Consecutive patients who underwent ERCP procedures at our hospital between January2008 and June 2013 were retrospectively enrolled in the study(n=2674).All procedures had been carried out using digital fluoroscopic assistance with the patient under conscious sedation.For patients showing alterations in the gastrointestinal anatomy,a short-type double balloon enteroscope had been applied.Cases of perforation had been identified by the presence of air in or leakage of contrast medium into the retroperitonealspace,or upon endoscopic detection of an abdominal cavity related to the perforated lumen.For patients with ERCP-related perforations,the data on medical history,endoscopic findings,radiologic findings,diagnostic methods,management,and clinical outcomes were used for descriptive analysis.RESULTS:Of the 2674 ERCP procedures performed during the 71-mo study period,only six(0.22%)resulted in perforations(male/female,2/4;median age:84 years;age range:57-97 years).The cases included an endoscope-related duodenal perforation,two periampullary perforations related to endoscopic sphincterotomy,two periampullary perforations related to endoscopic papillary balloon dilation,and a periampullary or bile duct perforation secondary to endoscopic instrument trauma.No cases of guidewire-related perforation occurred.The video endoscope system employed in all procedures was only able to immediately detect the endoscope-related perforation;the other five perforation cases were all detected by subsequent digital fluoroscope applied intraoperatively(at a median post-ERCP intervention time of 15 min).Three out of the six total perforation cases,including the single case of endoscope-related duodenal injury,were surgically treated;the remaining three cases were treated with conservative management,including trans-arterial embolization to control the bleeding in one of the cases.All patients recovered without further incident.CONCLUSION:ERCP-related perforations may be difficult to diagnose by video endoscope and digital fluoroscope detection of retroperitoneal free air or contrast medium leakage can facilitate diagnosis. | Yasuaki Motomura Kazuya Akahoshi Junya Gibo Kenji Kanayama Shinichiro Fukuda Shouhei Hamada Yoshihiro Otsuka Masaru Kubokawa Kiyoshi Kajiyama Kazuhiko Nakamura | 2014 | World Journal of Gastroenterology2014，20，42： | 5 |
