| 1 | Type 2 diabetes mellitus and CA 19-9 levels显示文摘AIM:To prospectively investigate serum CA 19-9 levels in type 2 diabetic patients in comparison with age-and gender-matched control subjects. METHODS:We recorded duration of diabetes and examined fasting glucose levels,HbA1c levels and serum CA 19-9 levels in 76 type 2 diabetic patients and 76 controls.Abdominal CT was performed in order to eliminate abdominal malignancy in the diabetic and control groups. RESULTS:The average CA 19-9 level was 46.0±22.4 U/mL for diabetic patients whereas it was 9.97±7.1 U/mL for the control group(P<0.001).Regression analysis showed a positive correlation between diabetes and CA 19-9 independent from age,gender,glucose level and HbA1c level(t=8.8,P<001).Two of the diabetic patients were excluded from the study because of abdominal malignancy shown by CT at the initial evaluation.For all patients,abdominal CT showed no pancreatic abnormalities. CONCLUSION:CA 19-9 is a tumor-associated antigen, which is elevated in pancreatic,upper gastrointestinal tract,ovarian hepatocellular,and colorectal cancers,as well as in inflammatory conditions of the hepatobiliary system,biliary obstruction and in thyroid diseases. Diabetes has been claimed to be a risk factor for pancreatic cancer,which is increasing its incidence and has one of the lowest survival rates of all cancers.CA 19-9 is used in the diagnosis of pancreatic cancer but is also a marker of pancreatic tissue damage that might be caused by diabetes.We propose that a higher cut- off value of CA 19-9 should be used in diabetics to differentiate benign and malignant pancreatic disease, and subtle elevations of CA 19-9 in diabetics should be considered as the indication of exocrine pancreatic dysfunction. | Oya Uygur-Bayramicli Resat Dabak Ekrem Orbay Can Dolapclo■lu Mehmet Sargin Gamze Kilico■lu Yüksel Güleryüzlü Alpaslan Mayada■li | 2007 | World Journal of Gastroenterology2007，13，40： | 63 |
| 2 | Current clinical management of gastrointestinal stromal tumor显示文摘Gastrointestinal stromal tumors(GISTs) are the most common malignant subepithelial lesions(SELs) of the gastrointestinal tract. They originate from the interstitial cells of Cajal located within the muscle layer and are characterized by over-expression of the tyrosine kinase receptor KIT. Pathologically, diagnosis of a GIST relies on morphology and immunohistochemistry [KIT and/or discovered on gastrointestinal stromal tumor 1(DOG1) is generally positive]. The prognosis of this disease is associated with the tumor size and mitotic index. The standard treatment of a GIST without metastasis is surgical resection. A GIST with metastasis is usually only treated by tyrosine kinase inhibitors without radical cure; thus, early diagnosis is the only way to improve its prognosis. However, a GIST is usually detected as a SEL during endoscopy, and many benign and malignant conditions may manifest as SELs. Conventional endoscopic biopsy is difficult for tumors without ulceration. Most SELs have therefore been managed without a histological diagnosis. However, a favorable prognosis of a GIST is associated with early histological diagnosis and R0 resection. Endoscopic ultrasonography(EUS) and EUS-guided fine needle aspiration(EUSFNA) are critical for an accurate diagnosis of SELs. EUSFNA is safe and effective in enabling an early histological diagnosis and adequate treatment. This review outlines the current evidence for the diagnosis and management of GISTs, with an emphasis on early management of small SELs. | Kazuya Akahoshi Masafumi Oya Tadashi Koga Yuki Shiratsuchi | 2018 | World Journal of Gastroenterology2018，24，26： | 70 |

| 4 | A clinical dilemma:abdominal tuberculosis显示文摘AIM: To evaluate the clinical, radiological and microbiological properties of abdominal tuberculosis (TB) and to discuss methods needed to get the diagnosis.METHODS: Thirty-one patients diagnosed as abdominal TB between March 1998 and December 2001 at the Gastroenterology Department of Kartal State Hospital,Istanbul, Turkey were evaluated prospectively. Complete physical examination, medical and family history, blood count erythrocyte sedimentation rate, routine biochemical tests,Mantoux skin test, chest X-ray and abdominal ultrasonography (USG) were performed in all cases, whereas microbiological examination of ascites, upper gastrointestinal endoscopy, colonoscopy or barium enema, abdominal tomography, mediastinoscopy, laparoscopy or laparotomy were done when needed.RESULTS: The median age of patients (14 females, 17males) was 34.2 years (range 15-65 years). The most frequent symptoms were abdominal pain and weight loss.Eleven patients had active pulmonary TB. The most common abdominal USG findings were ascites and hepatomegaly. Ascitic fluid analysis performed in 13 patients was found to be exudative and acid resistant bacilli were present in smear and cultured only in one patient with BacTec (3.2 %). Upper gastrointestinal endoscopy yielded nonspecific findings in 16 patients. Colonoscopy performed in 20 patients showed ulcers in 9 (45 %), nodules in 2 (10 %)and, stricture, polypoid lesions, granulomatous findings in terminal ileum and rectal fistula each in one patient (5 %).Laparoscopy on 4 patients showed dilated bowel loops,thickening in the mesentery, multiple ulcers and tubercles on the peritoneum. Patients with abdominal TB were divided into three groups according to the type of involvement.Fifteen patients (48 %) had intestinal TB, L1 patients (35.2 %) had tuberculous peritonitis and 5 (16.8 %)tuberculous lymphadenitis. The diagnosis of abdominal TB was confirmed microbiologically in 5 (16 %) and histopathologically in 19 patients (60.8 %). The remaining nine patients (28.8 %) had been diagnosed by a positive response to antituberculous treatment.CONCLUSION: Neither clinical signs, laboratory, radiological and endoscopic methods nor bacteriological and histopathological findings provide a gold standard by themselves in the diagnosis of abdominal TB. However, an algorithm of these diagnostic methods leads to considerably higher precision in the diagnosis of this insidious disease which primarily necessitate a clinical awareness of this serious health problem. | Oya Uygur-Bayramili Gül Dabak Resat Dabak | 2003 | World Journal of Gastroenterology2003，9，5： | 20 |

| 6 | Gastrointestinal stromal tumor of the stomach:How to manage?显示文摘Gastrointestinal stromal tumor (GIST) is one of the most common malignant mesenchymal tumors of the stomach. Prognosis of this disease is related to tumor size and mitotic activity and early diagnosis is the only way to improve it.Diagnosis of GIST always requires histological and immunohistochemical confirmation as no imaging modalities can diagnose it conclusively.Endoscopic forceps biopsy results are frequently negative. Endoscopic ultrasound-guided fine needle asp- iration (EUS-FNA) is a technique which allows tissue samples to be obtained with minimal risks and is accurate in the diagnosis of GIST. From the point of view of the endoscopist, aggressive use of EUS-FNA is the only promising way to allow early diagnosis and early treatment of this disease. | Kazuya Akahoshi Masafumi Oya | 2010 | World Journal of Gastrointestinal Endoscopy2010，2，8： | 16 |

| 8 | 为用离合器切割器的食道的小粒的房间肿瘤的内视镜的 submucosal 解剖显示文摘 Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate.The shortcomings of this method are the deficiencies of fixing the knife to the target lesion,and of compressing it.These shortcomings can lead to major complications such as perforation and bleeding.To reduce the risk of complications related to ESD,we developed a new grasping type scissors forceps (Clutch Cutter,Fujifilm,Japan) which can grasp and incise the targeted tissue using an electrosurgical current.Esophagogastroduodenoscopy on a 59-year-old Japanese man revealed a 16mm esophageal submucosal nodule with central depression.Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement.The histologic diagnosis of the specimen obtained by biopsy was granular cell tumor.It was safely and accurately resected without unexpected incision by ESD using the CC.No delayed hemorrhage or perforation occurred.Histological examination confirmed that the granular cell tumor was completely excised with negative resection margin.We report herein a case of esophageal granular cell tumor successfully treated by an ESD technique using the CC. | Keishi Komori Kazuya Akahoshi Yoshimasa Tanaka Yasuaki Motomura Masaru Kubokawa Soichi Itaba Terumasa Hisano Takashi Osoegawa Naotaka Nakama Risa Iwao Masafumi Oya Kazuhiko Nakamura | 2012 | World Journal of Gastrointestinal Endoscopy2012，4，1： | 8 |
| 9 | Risk factors and prevention of biliary anastomotic complications in adult living donor liver transplantation显示文摘AIM: To evaluate risk factors of biliary anastomotic complications (BACs) and outcomes according to type of biliary reconstruction. METHODS: A total of 33 consecutive adult living donor liver transplantation (LDLT) were reviewed, 17 of which had undergone Duct-to-Duct anastomosis (D-D). The remaining 16 patients received Roux-en-Y anastomosis (R-Y). The perioperative factors, such as the type of graft and the number of graft bile ducts, were analyzed retrospectively. RESULTS: The overall incidence of BACs was 39.4%. The incidence of BACs was significantly higher in the patients with than without neoadjuvant chemotherapy (71.4% vs 10%, P = 0.050). There was no signifi cant difference in the incidence of biliary leakage in patients with D-D vs those with R-Y. The incidence of biliary strictures following the healing of biliary leakage was significantly higher in D-D (60%) than in R-Y (0%) (P = 0.026). However, the incidence of BACs related bacteremia was signifi cantly higher in R-Y than in D-D (71.4% vs 0%, P = 0.008). In D-D, use of T-tube stent remarkably reduced the incidence of BACs, compared with straight tube stent (0% vs 50%, P = 0.049). CONCLUSION: Our experience showed an increase of BACs related bacteremia in the patients with R-Y. Therefore, D-D might be a preferred biliary reconstruction. However, the surgical refi nement of D-D should be required because of the high incidence of biliary strictures. Use of the T-tube stent might lead to a signifi cant reduction of BACs in D-D. | Satoshi Yamamoto Yoshinobu Sato Hiroshi Oya Hideki Nakatsuka Takashi Kobayashi Yoshiaki Hara Takaoki Watanabe Isao Kurosaki Katsuyoshi Hatakeyama | 2007 | World Journal of Gastroenterology2007，13，31： | 6 |
| 10 | Prognostic role of sensitive-to-apoptosis gene expression in rectal cancer显示文摘AIM:To investigate the association between prognosis of rectal cancer treated with chemoradiotherapy(CRT) and expression of sensitive-to-apoptosis(SAG),B-cell lymphoma-extra large(Bcl-X L) and Bcl-2 homologous antagonist/killer(Bak).METHODS:Real-time quantitative polymerase chain reaction was used to determine the expression of proteins of interest,namely SAG,Bcl-X L,Bak and β-actin,in rectal carcinoma patients who had a follow-up period of 3 years after CRT.Biopsy specimens were excised from the rectal tumor preceding CRT.RESULTS:SAG,Bcl-X L and Bak proteins showed significant correlations with each other.In multivariate analysis,patients with high vs low SAG expression showed a statistically significant difference in 2-year survival rates:56% vs 73%,respectively(P = 0.056).On the other hand,there were no significant correlations between the expression levels of all three genes and metastatic rates or tumor responses to CRT.Mean overall survival in the patients with elevated SAG expression was 27.1 mo ± 3.9 mo [95% confidence interval(CI):19.3-34.9],and in patients with reduced expression,it was 32.1 mo ± 2.5 mo(95% CI:27.3-36.9).The corresponding values for Bcl-X L were 28.0 mo ± 4.1 mo(95% CI:19.9-36.1) and 31.7 mo ± 2.9 mo(95% CI:26.0-37.5),and those for Bak were 29.8 mo ± 3.7 mo(95% CI:22.5-37.2) and 30.6 mo ± 2.4 mo(95% CI:25.5-35.0),respectively.CONCLUSION:Two-year survival rates significantly correlated with low SAG expression,and SAG may be a candidate gene for good prognosis,independent of therapeutic response of different individuals. | Sevgi A Ozden Hazan Ozyurt Zerrin Ozgen Olca Kilinc Mustafa Oncel Aylin E Gul Nimet Karadayi Nedime Serakinci Beki Kan Oya Orun | 2011 | World Journal of Gastroenterology2011，17，44： | 6 |

| 16 | Treatment of colorectal carcinoids:A new paradigm显示文摘It is often difficult to evaluate the grade of malignancy and choose an appropriate treatment for colorectal carcinoids in clinical settings. Although tumor size and depth of invasion are evidently not enough to stratify the risk of this rare tumor, the present guidelines or staging systems do not mention other clinicopathological variables. Recent studies, however, have shed light on the impact of lymphovascular invasion on the outcome of colorectal carcinoids. It has been revealed that the presence of lymphovascular invasion was among the strongest risk factors for metastasis along with tumor size and depth of invasion. Furthermore, tumors smaller than 1 cm, within submucosal invasion and without lymphovascular invasion, carry minimal risk for metastasis with 100% 5-year survival in the studies from Japan as well as from the USA. This would suggest that these tumors could be curatively treated by endoscopic resection or transanal local excision. On the other hand, colorectal carcinoids with either lymphovascular invasion or tumor size larger than 1 cm carry the risk for metastasis equivalent to adenocarcinomas. Therefore, it should be emphasized that histological examination of lymphovascular invasion is mandatory in the specimens obtained by endoscopic resection or transanal local excision, as this would provide useful information for determining the need for additional radical surgery with regional lymph node dissection. Although the present guidelines or TNM staging system do not mention the impact of lymphovascular invasion, this would be among the next promising targets in order to establish better guidelines and staging systems, particularly in early-stage colorectal carcinoids. | Tsuyoshi Konishi Toshiaki Watanabe Hirokazu Nagawa Masatoshi Oya Masashi Ueno Hiroya Kuroyanagi Yoshiya Fujimoto Takashi Akiyoshi Toshiharu Yamaguchi Tetsuichiro Muto | 2010 | World Journal of Gastrointestinal Surgery2010，2，5： | 5 |
| 17 | Clinical outcomes of Clutch Cutter endoscopic submucosal dissection for older patients with early gastric cancer显示文摘AIM To evaluate the clinical outcome of endoscopic submucosal dissection using the Clutch Cutter(ESDCC) in older patients. METHODS We reviewed 232 consecutive patients with early gastric cancer who underwent ESDCC between June 2010 and February 2014 at Aso Iizuka Hospital. We divided patients into two groups according to age: Older patients(> 80 years, n = 64) and non-older patients(≤ 80 years, n = 168). We retrospectively compared the prevalence rates of pre-existing comorbidities, anticoagulant therapy, en bloc resection, mean duration of hospitalization, incidence of ESDCC-related complications, change in performance status(PS) before and after ESDCC, and financial cost of admission. RESULTS The older group comprised 64 patients with a mean age of 84.1 years, and the non-older group comprised 168 patients with a mean age of 69.5 years. Older patients had significantly more pre-existing comorbidities than did non-older patients, specifically heart disease(P < 0.05). The en bloc resection rate in non-older patients was significantly higher than that in older patients(100% vs 95.3%, P = 0.02). There were no significant differences between the older and non-older groups in the incidence of ESDCC-related complications(i.e., postoperative bleeding and perforation) and the post-ESDCC change in PS. There were also no significant differences between the older and non-older groups in the mean duration of hospitalization(11.4 and 10.7 d, respectively) and financial cost of admission(657040 JPY and 574890 JPY, respectively).CONCLUSION ESDCC has a good clinical outcome in older patients. | Yoshihiro Otsuka Kazuya Akahoshi Kayoko Yasunaga Masaru Kubokawa Junya Gibo Shigeki Osada Kayo Tokumaru Kazuaki Miyamoto Takao Sato Yuki Shiratsuchi Masafumi Oya Hidenobu Koga Eikichi Ihara Kazuhiko Nakamura | 2017 | World Journal of Gastrointestinal Oncology2017，9，10： | 4 |
| 18 | Can platelet count/spleen diameter ratio be used for cirrhotic children to predict esophageal varices?显示文摘AIM To determine the laboratory and radiologic parameters, including the platelet count(PC)-to-spleen diameter(SD) ratio as a non-invasive marker that may predict the presence of esophageal varices(EV) in children with cirrhosis.METHODS Eighty-nine patients with cirrhosis, but without a history of variceal bleeding were prospectively included. The children were grouped into 6-12 and 12-18 years of age groups. These groups were also divided into 2 subgroups(presence and absence of EV). All of the patients underwent a complete biochemical and radiologic evaluation. The PC(n/mm^3)-to-SD(mm) ratio was calculated for each patient. RESULTS Sixty-nine of 98(70.4%) patients had EV. The presence of ascites in all age groups was significantly associatedwith the presence of EV. There were no differences in serum albumin levels, PC, SD and the PC-to-SD ratio between the presence and absence of EV groups in both age groups(P > 0.05). CONCLUSION Laboratory and radiologic parameters, including the PC-to-SD ratio as a non-invasive marker(except for the presence of ascites), was inappropriate for detecting EV in children with cirrhosis. | Oya Balci Sezer Deniz Celik Nihal Tutar Figen Ozcay | 2016 | World Journal of Hepatology2016，8，33： | 4 |
| 19 | Endoscopic submucosal dissection of a rectal carcinoid tumor using grasping type scissors forceps显示文摘Endoscopic submucosal dissection (ESD) with a knife is a technically demanding procedure associated with a high complication rate. The shortcomings of this method are the inability to fix the knife to the target lesion, and compression of the lesion. These can lead to major complications such as perforation and bleeding. To reduce the risk of complications related to ESD, we developed a new grasping type scissors forceps (GSF), which can grasp and incise the targeted tissue using electrosurgical current. Colonoscopy on a 55-year-old woman revealed a 10-mm rectal submucosal nodule. The histological diagnosis of the specimen obtained by biopsy was carcinoid tumor. Endoscopic ultrasonography demonstrated a hypoechoic solid tumor limited to the submucosa without lymph node involvement. It was safely and accurately resected without unexpected incision by ESD using a GSF. No delayed hemorrhage or perforation occurred. Histological examination confirmed the carcinoid tumor was completely excised with negative resection margin. | Kazuya Akahoshi Yasuaki Motomura Masaru Kubokawa Noriaki Matsui Manami Oda Risa Okamoto Shingo Endo Naomi Higuchi Yumi Kashiwabara Masafumi Oya Hidefumi Akahane Haruo Akiba | 2009 | World Journal of Gastroenterology2009，15，17： | 4 |
