| 2 | Factors determining delay in relaparotomy for anastomotic leakage after colorectal resection显示文摘AIM: To analyze the time interval ('delay') between the first occurrence of clinical parameters associated with anastomotic leakage after colorectal resection and subsequent relaparotomy. METHODS: In 36 out of 289 consecutive patients with colorectal anastomosis, leakage was confirmed at relaparotomy. The medical records of these patients were retrospectively analysed and type and time of appearance of clinical parameters suggestive of anastomotic leakage were recorded. These parameters included heart rate, body temperature, local or generalized peritoneal reaction, leucocytosis, ileus and delayed gastric emptying. Factors influencing delay of relaparotomy and consequences of delayed recognition and treatment were determined. RESULTS: First documentation of at least one of the predefined parameters for anastomotic leakage was after a median interval of 4 ± 1.7 d after the operation. The median number of days between first parameter(s) associated with leakage and relaparotomy was 3.5 ± 5.7 d. The time interval between the first signs of leakage and relaparotomy was significantly longer when a weekend was included (4.2 d vs 2.4 d, P = 0.021) or radiological evaluation proved to be false-negative (8.1 d vs 3.5 d, P = 0.007). No significant association between delay and number of additional relaparotomies, hospital stay or mortality could be demonstrated. CONCLUSION: An intervening weekend and negative diagnostic imaging reports may contribute to a delay in diagnosis and relaparotomy for anastomotic leakage. That delay was more than two days in two-thirds of the patients. | A Doeksen PJ Tanis BC Vrouenraets JJB Lanschot van WF Tets van | 2007 | World Journal of Gastroenterology2007，13，27： | 17 |
| 3 | A rare case of hyaline-type Castleman disease in the liver显示文摘Castleman disease often develops in the neck, mediastinum and pulmonary hilum. Its onset in the peritoneal cavity is very rare. The patient, a woman in her 70s, was referred to our department for a detailed examination of an abdominal mass. On abdominal ultrasonography, computed tomography scan, magnetic resonance imaging and positron emission tomography, a mass approximately 15 mm in diameter was noted in the hepatic S6. We attempted radical treatment and conducted a laparoscope-assisted right lobectomy. On the basis of histopathological findings, the patient was diagnosed as having hyaline type Castleman disease in the liver, a very rare condition. | Hisaaki Miyoshi Shima Mimura Takako Nomura Joji Tani Asahiro Morishita Hideki Kobara Hirohito Mori Hirohito Yoneyama Akihiro Deguchi Takashi Himoto Naoki Yamamoto Keiichi Okano Yasuyuki Suzuki Tsutomu Masaki | 2013 | World Journal of Hepatology2013，5，7： | 14 |
| 4 | Treatment of colorectal cancer in the elderly显示文摘Colorectal cancer has a high incidence, and approxi-mately 60% of colorectal cancer patients are older than 70, with this incidence likely increasing in the near future. Elderly patients(> 70-75 years of age) are a very heterogeneous group, ranging from the very fit to the very frail. Traditionally, these patients have often been under-treated and recruited less frequently to clinical trials than younger patients, and thus are underrepresented in publications about cancer treatment. Recent studies suggest that fit elderly patients can be treated in the same way as their younger counterparts, but the treatment of frail patients with comorbidities is still a matter of controversy. Many factors should be taken into account, including fitness for treatment, the wishes of the patient and family, and quality of life. This review will focus on the existing evidence for surgical, oncologic, and palliative treatment in patients over 70 years old with colorectal cancer. Careful patient assessment is necessary in order to individualize treatment approach, and this should rely on a multidisciplinary process. More well-designed controlled trials are needed in this patient population. | Monica Millan Sandra Merino Aleidis Caro Francesc Feliu Jordi Escuder Tani Francesch | 2015 | World Journal of Gastrointestinal Oncology2015，7，10： | 9 |
| 5 | Reduction effect of bacterial counts by preoperative saline lavage of the stomach in performing laparoscopic and endoscopic cooperative surgery显示文摘AIM:To investigate the effects of gastric lavage with2000 mL of saline in laparoscopic and endoscopic cooperative surgery.METHODS:Twenty two patients who were diagnosed with a gastric gastrointestinal stromal tumor were enrolled.In former term,irrigations of the stomach were conducted whenever it was necessary,not systematically(Non systemic lavage group).In latter term,the stomach was thoroughly cleaned with 2000 mL of saline using an endoscope with a water jet,and Duodenal balloon occlusion was conducted to prevent refluxedbile and pancreatic juice(Systemic lavage+balloon occlusion group).The gastric wall was sprayed with 20mL of distilled water,and 20 mL of gastric juice was collected in a sterile tube and submitted for culture.20mL of ascites was also collected from the laparoscopic ports and submitted for culture.We compared WBC,CRP,BT between two groups,and verify the reduction effect of bacterial counts in Systemic lavage+balloon occlusion group.RESULTS:WBC count before,1 d after,and 3 d after laparoscopic and endoscopic cooperative surgery(LECS)were 5060(95%CI:4250-9640),12140(6050-14110),and 6910(5320-12520)in Non systemic lavage group,4400(3660-7620),8910(6480-10980),and 5950(4840-7860)in Systemic lavage+balloon occlusion group.Significant differences between two groups at the day after LECS(P=0.029)and the 3 d after LECS(P=0.042).CRP levels in Non systemic lavage group and in Systemic lavage+balloon occlusion group were significantly different at the day after LECS(P=0.005)and the 3 d after LECS(P=0.028).BTs(℃)in Non systemic lavage group and in Systemic lavage+balloon occlusion group were also significantly different at the day after LECS(P=0.004)and the 3 d after LECS(P=0.006).In a logarithmic comparison,bacterial load before gastric lavage,after lavage,and ascites culture were 6.08(95%CI:4.04-6.97),0.48(0-0.85),and 0.21(0-0.56).The bacterial counts before and after gastric lavage were significantly suppressed(P=0.007),but no significant difference between gastric juice culture after lavage and ascites(P=0.154).CONCLUSION:Pre-LECS lavage with 2000 mL of saline exhibited a bacteria-reducing effect equivalent to disinfectants and obtained favorable results in terms of clinical symptoms and data. | Hirohito Mori Hideki Kobara Takaaki Tsushimi Shintaro Fujihara Noriko Nishiyama Tae Matsunaga Maki Ayaki Tatsuo Yachida Joji Tani Hisaaki Miyoshi Asahiro Morishita Tsutomu Masaki | 2014 | World Journal of Gastroenterology2014，20，42： | 9 |
| 6 | Laparoscopic cholecystectomy in situs inversus totalis with “inferior” cystic artery: A case report显示文摘A 76-year-old man with known situs inversus totalis presented with left-sided discomfort. Abdominal ultrasonography and CT scan confirmed the diagnosis of a gallstone, as well as,situs inversus; the liver and gallbladder on the left side and the spleen on the right. The biliary system was thought to be left-right reversal, mirror image in the view of drip infusion cholangiogram and MRI. Laparoscopic cholecy stectomywas safely performed, despite of unexpected aberrant cystic artery running inferior to cystic duct of situs inversus.Laparoscopic surgeon should be careful for view of reversed relationships and also existence of other anomalies. | Sumihiro Kamitani Yosihiro Tsutamoto Kazuyoshi Hanasawa Tohru Tani | 2005 | World Journal of Gastroenterology2005，11，33： | 8 |
| 7 | Pseudolymphoma of the liver associated with primary biliary cirrhosis:A case report and review of literature显示文摘We report a case of two pseudolymphomas of the liver in a 63-year-old Japanese woman with primary biliary cirrhosis.One of the lesions was found incidentally during a medical examination,presenting as a 10 mm hypodense nodule that revealed hyperdensity in the early phase and hypodensity in the late phase in computed tomography(CT)after injection of contrast medium.Retrospectively,the 10 mm nodule had first been discovered as a 4 mm nodule during CT 4 years previously.Superparamagnetic iron oxide-enhanced MRI revealed another 4 mm hyperintense nodule in segment 6 in addition to the 10 mm hyperintense nodule in segment 7.CT during arterial portography revealed two hypointense nodules.Findings with other imaging modalities such as ultrasonography,magnetic resonance imaging,and hepatic angiography were consistent with hepatocellular carcinoma.A right posterior segmentectomy was performed,and the lesions were microscopically diagnosed as pseudolymphoma.To the best of our knowledge,only 31 other cases of this disease have ever been reported,with a highly asymmetrical male:female ratio of 1:9.7.Although we could find only one case of transformation of hepaticpseudolymphoma into lymphoma in the liver,the exact nature of development from benign pseudolymphoma to malignant lymphoma is still not fully understood and cases of hepatic lymphoma need to be followed carefully. | Toshihide Okada Hiroshi Mibayashi Kenkei Hasatani Yoshiaki Hayashi Shigetsugu Tsuji Yoshibumi Kaneko Masashi Yoshimitsu Takashi Tani Yoh Zen Masakazu Yamagishi | 2009 | World Journal of Gastroenterology2009，15，36： | 8 |
| 8 | Clinical significance of molecular diagnosis for gastric cancer lymph node micrometastasis显示文摘Advances in molecular diagnostic tools have allowed the identification of lymph node micrometastasis(LNM),including isolated tumor cells,in cancer patients. While immunohistochemistry and reverse transcription-polymerase chain reaction have been used to identify LNM in patients with gastric cancer,the clinical significance of this finding remains unclear. Recently,minimally invasive treatments,such as endoscopic submucosal dissection and laparoscopic surgery,are widely performed to help improve postsurgical quality of life(QOL). However,it is important to maintain the balance between QOL and curability when making treatments decision for patients with gastric cancer. If minimally invasive surgery based on accurate intraoperative LNM diagnosis was established,it could be performed safely. Therefore,we reviewed the clinical significance of LNM detected by molecular techniques as an important target for treatment decision making with gastric cancer patients. | Hiromichi Sonoda Tohru Tani | 2014 | World Journal of Gastroenterology2014，20，38： | 8 |
| 9 | Diabetes mellitus and metformin in hepatocellular carcinoma显示文摘Hepatocellular carcinoma(HCC) is the leading cause of cancer-related death worldwide. Diabetes mellitus, a risk factor for cancer, is also globally endemic. The clinical link between these two diseases has been the subject of investigation for a century, and diabetes mellitus has been established as a risk factor for HCC. Accordingly, metformin, a first-line oral anti-diabetic, was first proposed as a candidate anti-cancer agent in 2005 in a cohort study in Scotland. Several subsequent large cohort studies and randomized controlled trials have not demonstrated significant efficacy for metformin in suppressing HCC incidence and mortality in diabetic patients; however, two recent randomized controlled trials have reported positive data for the tumor-preventive potential of metformin in non-diabetic subjects. The search for biological links between cancer and diabetes has revealed intracellular pathways that are shared by cancer and diabetes. The signal transduction mechanisms by which metformin suppresses carcinogenesis in cell lines or xenograft tissues and improves chemoresistance in cancer stem cells have also been elucidated. This review addresses the clinical and biological links between HCC and diabetes mellitus and the anti-cancer activity of metformin in clinical studies and basic experiments. | Koji Fujita Hisakazu Iwama Hisaaki Miyoshi Joji Tani Kyoko Oura Tomoko Tadokoro Teppei Sakamoto Takako Nomura Asahiro Morishita Hirohito Yoneyama Tsutomu Masaki | 2016 | World Journal of Gastroenterology2016，22，27： | 7 |
| 10 | Efficient gasification of wet biomass residue to produce middle caloric gas显示文摘Various process residues represent a kind of biomass resource already concentrated but containing water as much as 60 wt.%.These materials are generally treated as waste or simply combusted directly to generate heat.Recently,we attempted to convert them into middle caloric gas to substitute for natural gas,as a chemical or a high-rank gaseous fuel for advanced combustion utilities.Such conversion is implemented through dual fluidized bed gasification(DFBG).Concerning the high water content of the fuels,DFBG was suggested to accomplish either with high-efficiency fuel drying in advance or direct decoupling of fuel drying/pyrolysis from char gasification and tar/hydrocarbon reforming.Along with fuel drying, calcium-based catalyst can be impregnated into the fuel,without much additional cost,to increase the fuel’s gasification reactivity and to reduce tar formation.This article reports the Ca impregnation method and its resulting effects on gasification reactivity and tar suppression ability.Meanwhile, the principle of directly gasifying wet fuel with decoupled dual fluidized bed gasification(D-DFBG)is also highlighted. | Guangwen Xu Takahiro Murakami Toshiyuki Suda Hidehisa Tani Yutaka Mito | 2008 | Particuology2008，6，5： | 7 |
| 11 | A rare case of primary choriocarcinoma in the sigmoid colon显示文摘Primary colorectal choriocarcinoma is an extremely rare neoplasm and is usually associated with a poor prognosis.Only 13 cases of colorectal choriocarcinoma have previously been reported.There is no standard chemotherapeutic regimen for this tumor type.A 68-year-old man presented with melena and was diagnosed with sigmoid colonic adenocarcinoma with multiple liver metastases.He underwent a laparoscopic sigmoidectomy.Pathology revealed choriocarcinoma with a focal component of moderately differentiated adenocarcinoma of colon origin.Based on the collagen gel droplet-embedded culture drug sensitivity test(CD-DST)results,mFOLFOX6 and bevacizumab were administered,which suppressed aggressive tumor growth for 4 mo.The patient died 9 mo after the initial diagnosis.Our study results suggest that the standard chemotherapy regimen for colorectal cancer might have suppressive effects against primary colorectal choriocarcinoma.Moreover,CD-DST may provide,at least in part,therapeutic insight for the selection of appropriate antitumor agents for such patients. | Hiromitsu Maehira Tomoharu Shimizu Hiromichi Sonoda Eiji Mekata Tomoharo Yamaguchi Tohru Miyake Mitsuaki Ishida Tohru Tani | 2013 | World Journal of Gastroenterology2013，19，39： | 6 |
| 12 | Sentinel lymph node navigation surgery for gastric cancer: Does it really benefit the patient?显示文摘Sentinel lymph node(SLN) navigation surgery is accepted as a standard treatment procedure for malignant melanoma and breast cancer. However, the benefit of reduced lymphadenectomy based on SLN examination remains unclear in cases of gastric cancer. Here, we review previous studies to determine whether SLN navigation surgery is beneficial for gastric cancer patients. Recently, a large-scale prospective study from the Japanese Society of Sentinel Node Navigation Surgery reported that the endoscopic dual tracer method, using a dye and radioisotope for SLN biopsy, was safe and effective when applied to cases of superficial and relatively small gastric cancers. SLN mapping with SLN basin dissection was preferred for early gastric cancer since it is minimally invasive. However, previous studies reported that limited gastrectomy and lymphadenectomy may not improve the patient's postoperative quality of life(QOL). As a result, the benefit of SLN navigation surgery for gastric cancer patients, in terms of their QOL, is limited. Thus, endoscopic and laparoscopic limited gastrectomy combined with SLN navigation surgery has the potential to become the standard minimally invasive surgery in early gastric cancer. | Tohru Tani Hiromichi Sonoda Masaji Tani | 2016 | World Journal of Gastroenterology2016，22，10： | 6 |

| 14 | Non-Epstein-Barr virus associated lymphoepithelioma-like carcinoma of the inferior common bile duct显示文摘A carcinoma displaying undifferentiated features with dense lymphoplasmacytic infiltration is defined as a lymphoepithelioma-like carcinoma(LEC),and some of LEC is associated with Epstein-Barr virus(EBV).All of the 13 previously reported cases of LEC of the biliary system were intrahepatic in location.Herein,we describe the first case of LEC of the inferior common bile duct.A 68-year-old Japanese man,who had been previously treated for hepatocellular carcinoma using microwave coagulation therapy,was found to have tumors of the common bile duct and pancreas head.Histopathological study of the resected tumor showed solid or cohesive nests of large undifferentiated cells with irregular large vesicular nuclei and nucleoli.Around the tumor cell nests,dense lymphoplasmacytic infiltration was observed.Focal glandular differentiation(approximately 5%) was also present.These histopathological features corresponded morphologically to LEC.Immunohistochemically,the tumor cells were positive for cytokeratin(CK) 7,CK 19 and CA19-9,but negative for CK 20 and Hep Par 1.In situ hybridization for Epstein Barr virus early small RNAs disclosed no nuclear signal in tumor cells.Therefore,a diagnosis of non-EBV-associated LEC of the inferior common bile duct was made.Although the prognosis of the biliary LEC is thought to be better than that of conventional cholangiocarcinoma,the differences in prognosis between EBV-positive and-negative cases have not yet been established.Therefore,additional case studies will be needed to clarify the clinicopathological features of LEC of the biliary tract. | Mitsuaki Ishida Tsuyoshi Mori Hisanori Shiomi Shigeyuki Naka Tomoyuki Tsujikawa Akira Andoh Yasuharu Saito Yoshimasa Kurumi Fumiyoshi Kojima Machiko Hotta Tohru Tani Yoshihide Fujiyama Hidetoshi Okabe | 2011 | World Journal of Gastrointestinal Oncology2011，3，7： | 5 |
| 15 | Percutaneous radiofrequency ablation for early hepatocellular carcinoma: Risk factors for survival显示文摘AIM: To evaluate outcomes of radiofrequency ablation(RFA) therapy for early hepatocellular carcinoma(HCC) and identify survival- and recurrence-related factors. METHODS: Consecutive patients diagnosed with early HCC by computed tomography(CT) or magnetic resonance imaging(MRI)(single nodule of ≤ 5 cm, or multi-(up to 3) nodules of ≤ 3 cm each) and who underwent RFA treatment with curative intent between January 2010 and August 2011 at the Instituto do Cancer do Estado de S o Paulo, Brazil were enrolled in the study. RFA of the liver tumors(with 1.0 cm ablative margin) was carried out under CT-fluoro scan and ultrasonic image guidance of the percutaneous ablation probes. Procedure-related complications were recorded. At 1-mo post-RFA and 3-mo intervals thereafter, CT and MRI were performed to assess outcomes of complete response(absence of enhancing tissue at the tumor site) or incomplete response(enhancing tissue remaining at the tumor site). Overall survival and diseasefree survival rates were estimated by the Kaplan-Meier method and compared by the log rank test or simple Cox regression. The effect of risk factors on survival was assessed by the Cox proportional hazard model. RESULTS: A total of 38 RFA sessions were performed during the study period on 34 patients(age in years: mean, 63 and range, 49-84). The mean follow-up time was 22 mo(range, 1-33). The study population showed predominance of male sex(76%), less severe liver disease(Child-Pugh A, n = 26; Child-Pugh B, n = 8), and single tumor(65%). The maximum tumor diameters ranged from 10 to 50 mm(median, 26 mm). The initial(immediately post-procedure) rate of RFAinduced complete tumor necrosis was 90%. The probability of achieving complete response was significantly greater in patients with a single nodule(vs patients with multi-nodules, P = 0.04). Two patients experienced major complications, including acute pulmonary edema(resolved with intervention) and intestinal perforation(led to death). The 1- and 2-year overall survival rates were 82% and 71%, respectively. Sex, tumor size, initial response, and recurrence status influenced survival, but did not reach the threshold of statistical significance. Child-Pugh class and the model for end-stage liver disease score were identified as predictors of survival by simple Cox regression, but only Child-Pugh class showed a statistically significant association to survival in multiple Cox regression analysis(HR = 15; 95%CI: 3-76 mo; P = 0.001). The 1-and 2-year cumulative disease-free survival rates were 65% and 36%, respectively. CONCLUSION: RFA is an effective therapy for local tumor control of early HCC, and patients with preserved liver function are the best candidates. | Luciana Kikuchi Marcos Menezes Aline L Chagas Claudia M Tani Regiane SSM Alencar Marcio A Diniz Venncio AF Alves Luiz Augusto Carneiro D’Albuquerque Flair José Carrilho | 2014 | World Journal of Gastroenterology2014，20，6： | 5 |

| 17 | Pulmonary tumor thrombotic microangiopathy of hepatocellular carcinoma: A case report and review of literature显示文摘BACKGROUND Pulmonary tumor thrombotic microangiopathy(PTTM)is a rare condition in patients with hepatocellular carcinoma(HCC);to date,few cases have been reported.While hepatic dysfunction has been focused on the later stages of HCC,the management of symptoms in PTTM is important for supportive care of the cases.For the better understanding of PTTM in HCC,the information of our recent case and reported cases have been summarized.CASE SUMMARY A patient with HCC exhibited acute and severe respiratory failure.Radiography and computed tomography of the chest revealed the multiple metastatic tumors and a frosted glass–like shadow with no evidence of infectious pneumonia.We diagnosed his condition as acute respiratory distress syndrome caused by the lung metastases and involvement of the pulmonary vessels by tumor thrombus.Administration of prednisolone to alleviate the diffuse alveolar damages including edematous changes of alveolar wall caused by the tumor cell infiltration and ischemia showed mild improvement in his symptoms and imaging findings.An autopsy showed the typical pattern of PTTM in the lung with multiple metastases.CONCLUSION PTTM is caused by tumor thrombi in the arteries and thickening of the pulmonary arterial endothelium leading to the symptoms of dyspnea in terminal staged patients.Therefore,supportive management of symptoms is necessary in the cases with PTTM and hence we believe that the information presented here is of great significance for the diagnosis and management of symptoms of PTTM with HCC. | Shinichi Morita Kenya Kamimura Hiroyuki Abe Yukari Watanabe-Mori Chiyumi Oda Takamasa Kobayashi Yoshihisa Arao Yusuke Tani Riuko Ohashi Yoichi Ajioka Shuji Terai | 2019 | World Journal of Gastroenterology2019，25，48： | 4 |
| 18 | Efficiency of HAART in the prevention of mother to children HIV-1 transmission at Saint Camille medical centre in Burkina Faso,West Africa显示文摘Objective:To evaluate efficiency of HAART in the prevention of mother to child HIV transmission.Methods:A longitudinal study was conducted on 1 300 women attending the antenatal service at Saint Camille Medical Centre from September 2010 to July 2011.The HIV status of mothers was determined by rapid tests and EUSA.Discordant results were confirmed by real-time PCR.PCR was used to determine HIV status of children born from HIV-positive mothers.Results:Among 1 300 pregnant women tested for HIV,378 were seropositive.Mothers were predominantly housewives(69.7%),and their mean age was(28.32±0.15) years.The overall prevalence of HIV transmission from mother to child was 4.8%(18/378).This prevalence differed significantly from 0.0%(0/114) to 6.8%(18/264) in children born from mothers under HAART and those with mothers under New Prophylactic Protocol(ACT + 3TC + NVP),respectively(P< 0.01).Children’s mortality rate during the medical follow up was 1.3%(5/378).Among 16 women with HIV dubious status by ELISA,the Real Time PCR confirmed 2/16(12.5%) as HIV positive. Conclusions:The protocol of prevention of mother to children HIV transmission(PMTCT) is effective.The rate of HIV vertical transmission is significantly reduced.Early diagnosis determined by PCR of children born from HIV- positive mother is necessary and recommended in the context of PMTCT in Burkina Faso.We also found that PCR is an effective tool to confirm HIV status in pregnant women. | Laure Stella Ghoma Linguissi Cyrille Bisseye Tani Sagna Bolni Marius Nagalo Djeneba Ouermi Florencia W Djigma Salvatore Pignatelli Joseph D Sia Virginio Pietra Remy Moret Jean Baptiste Nikiema Jacques Simpore | 2012 | Asian Pacific Journal of Tropical Medicine2012，5，12： | 4 |
| 19 | RNA interference against interleukin-5 attenuates airway inflammation and hyperresponsiveness in an asthma model显示文摘Interleukin-5 (IL-5) accompanies the development of airway inflammation and hyperresponsiveness through the activation of eosinophils. Therefore, interference of IL-5 expression in lung tissue seems to be an accepted approach in asthma therapy. In this study, we designed a small interfering RNA (siRNA) to inhibit the expression of IL-5. The siRNAs against IL-5 were constructed in a lentivirus expressing system, and 1.5×106 IFU (inclusion-forming unit) lentiviruses were administered intratracheally to ovalbumin (OVA)-sensitized murine asthmatic models. Our results show that lentivirus-delivered siRNA against IL-5 efficiently inhibited the IL-5 messenger ribonucleic acid (mRNA) expression and significantly attenuated the inflammation in lung tissue. Significant decrease of eosinophils and inflammatory cells were found in peripheral blood, bronchoalveolar lavage fluid (BALF), and lung tissue. In addition, significant inhibition of airway hyperresponsiveness (AHR) was found in the mice treated with siRNA against IL-5. These observations demonstrate that siRNA delivered by means of the lentivirus system is possibly an efficacious therapeutic approach for asthma. | Shao-xing CHEN Feng-ying HUANG Guang-hong TANi Cai-chun WANG Yong-hao HUANG Hua WANG Song-lin ZHOU Fan CHEN Ying-ying LIN Jun-bao LIU | 2009 | Journal of Zhejiang University-Science B(Biomedicine & Biotechnology)2009，10，1： | 4 |
| 20 | Possible role of human cytomegalovirus in pouchitis after proctocolectomy with ileal pouch-anal anastomosis in patients with ulcerative colitis显示文摘AIM: To detect the presence of human cytomegalovirus (HCMV) proteins and genes on the ileal pouch of patients with ulcerative colitis who have undergone proctocolectomy with ileal pouch-anal anastomosis (iPAA). METHODS: immunohistochemistry, polymerase chain reaction (PCR) and PCR sequencing methods were utilized to test the presence of HCMV in pouch specimens taken from 34 patients in 86 endoscopies. RESULTS: HCMV genes and proteins were detected in samples from 12 (35.2%) patients. The rate of detection was significant in the endoscopies from patients diagnosed with pouchitis (5 of 12, 41.6%), according to the Japanese classification of pouchitis, in comparison to patients with normal pouch (7 of 62, 11.2%; P = 0.021). in all patients with pouchitis in which the HCMV was detected, it was the first episode of pouchitis. The virus was not detected in previous biopsies taken in normal endoscopies of these patients. During the follow- up, HCMV was detected in one patient with recurrent pouchitis and in 3 patients whose pouchitis episodes improved but whose positive endoscopic findings persisted. CONCLUSION: HCMV can take part in the inflammatory process of the pouch in some patients with ulcerative colitis who have undergone proctocolectomy with iPAA. | Damian Casadesus Tatsuo Tani Toshifumi Wakai Satoshi Maruyama Tsuneo iiai Haruhiko Okamoto Katsuyoshi Hatakeyama | 2007 | World Journal of Gastroenterology2007，13，7： | 4 |
