| 1 | Small-for-size syndrome in liver transplantation:Definition,pathophysiology and management显示文摘Background:Since the first success in an adult patient,living donor liver transplantation(LDLT)has become an universally used procedure.Small-for-size syndrome(SFSS)is a well-known complication after partial LT,especially in cases of adult-to-adult LDLT.The definition of SFSS slightly varies among transplant physicians.The use of a partial liver graft has risks of SFSS development.Persistent portal vein(PV)hypertension and PV hyper-perfusion after LT were identified as the main factors.Hence,various approaches were explored to modulate PV flow and decrease PV pressure in order to alleviate this syndrome.Herein,the definition,clinical symptoms,pathophysiology,basic research,as well as preventive and treatment strategies for SFSS are reviewed based on an extensive review of the literature and on our own experiences.Data sources:The articles were collected through PubMed using search terms“liver transplantation”,“living donor liver transplantation”,“living liver donation”,“partial graft”,“small-for-size graft”,“small-forsize syndrome”,“graft volume”,“remnant liver”,“standard liver volume”,“graft to recipient body weight ratio”,“sarcopenia”,“porcine”,“swine”,and“rat”.English publications published before March 31,2020 were included in this review.Results:Many transplant surgeons performed PV flow modulation,including portocaval shunt,splenic artery ligation and splenectomy.With these techniques,patient outcome has been improved even when using a'small'graft.Other factors,such as preoperative recipients’nutritional and skeletal muscle status,graft congestion,and donor factors,were also identified as risk factors which all have been addressed using various strategies.Conclusions:The surgical approach controlling PV flow and pressure could help to prevent SFSS especially in severely ill recipients.In the absence of efficacious medications to resolve SFSS,conservative treatments,including aggressive fluid balance correction for massive ascites,anti-microbiological therapy to prevent or control sepsis and intensive nutritional therapy,are all required if SFSS could not be prevented. | Yuichi Masuda Kazuki Yoshizawa Yasunari Ohno Atsuyoshi Mita Akira Shimizu Yuji Soejima | 2020 | Hepatobiliary & Pancreatic Diseases International2020，19，4： | 13 |
| 2 | Efficacy of multislice computed tomography for gastroenteric and hepatic surgeries显示文摘AIM: To determine the efficacy of multislice CT for gastroenteric and hepatic surgery.METHODS: Dual-phase helical computed tomography was performed in 50 of 51 patients who underwent gastroenteric and hepatic surgeries. Twenty-eight, eighteen and four patients suffering from colorectal cancer, gastric cancer,and liver cancer respectively underwent colorectal surgery (laparoscopic surgery: 6 cases), gastrectomy, and hepatectomy. Three-dimensional computed tomography imaging of the inferior mesenteric artery, celiac artery and hepatic artery was performed. And in the follow-up examination of postoperative patients, multiplanar reconstruction image was made in case of need.RESULTS: Scans in 50 patients were technically satisfactory and included in the analysis. Depiction of major visceral arteries, which were important for surgery and other treatments, could be done in all patients.Preoperative visualization of the left colic artery and sigmoidal arteries, the celiac artery and its branches, and hepatic artery was very useful to lymph node dissection,the planning of a reservoir and hepatectomy. And multiplanar reconstruction image was helpful to diagnosis for the postoperative follow-up of patients.CONCLUSION: Three-dimensional volume rendering or multiplanar reconstruction imaging performed by multislice computed tomography was very useful for gastroenteric and hepatic surgeries. | Hiroshi Ohtani Hidemi Kawajiri Yuichi Arimoto Koichi Ohno Yasuhisa Fujimoto Hiroko Oba Kenji Adachi Masaya Hirano Shoichi Terakawa Mitsuo Tsubakimoto | 2005 | World Journal of Gastroenterology2005，11，10： | 9 |
| 3 | Comparison between sitagliptin and nateglinide on postprandial lipid levels: The STANDARD study显示文摘AIM: To assess the effects of sitagliptin and nateglinide on lipid metabolism. METHODS: In a parallel group comparative open trial, patients with type 2 diabetes mellitus under treatment at the Japanese Red Cross Medical Center were randomly assigned to receive either sitagliptin (50 mg once daily) or nateglinide (90 mg three times daily before meals). Eligible patients met the following criteria: age ≥ 20 years; hemoglobin A 1c (HbA 1c ) > 6.5% despite diet and exercise; HbA 1c between 6.5% and 8.0%; fasting glucose < 7.77 mmol/L; diet and exercise therapy for more than 3 mo; and ability to read and understand the information for written informed consent. Exclusion criteria were contraindications to sitagliptin, contraindications to nateglinide, pregnancy or possible pregnancy, and severe liver/renal failure. Patients who were considered to be unsuitable by the attending physician for other reasons were also excluded. Blood samples were collected at one and three hours after intake of a test meal. The primary outcome measure was the area under the curve (AUC) of apolipoprotein (Apo) B48 at three hours postprandially. RESULTS: Twenty patients were randomly assigned to the sitagliptin group and sixteen patients were randomized to the nateglinide group. All 36 patients took the medication as directed by the physician in both groups, and they all were analyzed. Apart from antidiabetic drugs, there was no difference between the two groups with respect to the frequency of combined use of lipid-lowering, antihypertensive, and/or antiplatelet drugs. The doses of these medications were maintained during 12 wk of treatment. Detailed dietary advice, together with adequate exercise therapy, was given to the patients so that other factors apart from the two test drugs were similar in the two groups. There were no significant differences of the baseline characteristics between the two groups, except for body mass index (the sitagliptin group: 25.14 ± 3.05 kg/m 2 ; the nateglinide group: 21.39 ± 2.24 kg/m 2 ). Fasting levels of HbA 1c , glycated albumin, 1.5-anhydroglucitol, and blood glucose, as well as the blood glucose levels at one and three hours postprandially, improved in both groups after 12 wk of treatment, and there were no significant differences between the two groups. However, the glucagon level at one hour postprandially (P = 0.040) and the diastolic blood pressure (P<0.01) only showed a significant decrease in the sitagliptin group. In the nateglinide group, there was no significant change in the AUC of Apo B48, the glucagon level at one hour postprandially, the fasting triglyceride level, or the diastolic blood pressure. Body weight was unchanged in both groups. However, the AUC of Apo B48 at three hours postprandially showed a significant decrease in the sitagliptin group from 2.48 ± 0.11 at baseline to 1.94 ± 0.78 g/L per hour after 12 wk (P=0.019). The fasting triglyceride level also decreased significantly in the sitagliptin group (P = 0.035). With regard to lipid-related markers other than Apo B48 and fasting triglycerides, no significant changes were observed with respect to Apo A1, Apo B, or Apo C3 in either group. No adverse events occurred in either group. CONCLUSION: Sitagliptin significantly improves some lipid parameters while having a comparable effect on blood glucose to nateglinide. A large-scale prospective study of sitagliptin therapy is warranted. | Yuichi Kojima Hideyoshi Kaga Shinu Hayashi Toru Kitazawa Yuko Iimura Makoto Ohno Michiyasu Yoshitsugu Mutsunori Fujiwara Toru Hiyoshi | 2013 | World Journal of Diabetes2013，4，1： | 5 |

| 8 | Clinical characteristics of gastrointestinal immune-related adverse events of immune checkpoint inhibitors and their association with survival显示文摘BACKGROUND Despite the popularity of immune checkpoint inhibitors(ICIs)in the treatment of advanced cancer,patients often develop gastrointestinal(GI)and non-GI immune-related adverse events(irAEs).The clinical characteristics and survival outcomes of GI-irAEs have not been fully elucidated in previous reports.This necessitates the evaluation of the impact of GI-irAEs on patients receiving ICI treatment.AIM To evaluate the clinical characteristics of GI-irAEs and their impact on survival in patients treated with ICIs.METHODS In this single-center,retrospective,observational study,we reviewed the records of 661 patients who received ICIs for various cancers at Nagoya University Hospital from September 2014 to August 2020.We analyzed the clinical characteristics of patients who received ICI treatment.We also evaluated the correlation between GI-irAE development and prognosis in non-small cell lung cancer(LC)and malignant melanoma(MM).Kaplan-Meier analysis was used to compare the median overall survival(OS).Multivariate Cox proportional hazards models were used to identify prognostic factors.A P value<0.05 was considered statistically significant.RESULTS GI-irAEs occurred in 34 of 605 patients(5.6%)treated with an anti-programmed cell death-1/programmed death-ligand 1(anti-PD-1/PD-L1)antibody alone and in nine of 56 patients(16.1%)treated with an anti-cytotoxic T-lymphocyte antigen 4(CTLA-4)antibody alone or a combination of anti-PD-1 and anti-CTLA-4 antibodies.The cumulative incidence and median daily diarrhea frequency were significantly higher in patients receiving anti-CTLA-4 antibodies(P<0.05).In 130 patients with MM,OS was significantly prolonged in the group that continued ICI treatment despite the development of GI-irAEs compared to the group that did not experience GI-irAEs(P=0.035).In contrast,in 209 patients with non-small cell LC,there was no significant difference in OS between the groups.The multivariate analyses showed that a performance status of 2-3(hazard ratio:2.406;95%confidence interval:1.125–5.147;P=0.024)was an independent predictive factor for OS in patients with MM.CONCLUSION Patients receiving anti-CTLA-4 antibodies develop GI-irAEs more frequently and with higher severity than those receiving anti-PD-1/PD-L1 antibodies.Continuing ICI treatment in patients with MM with GI-irAEs have better OS. | Kentaro Yamada Tsunaki Sawada Masanao Nakamura Takeshi Yamamura Keiko Maeda Eri Ishikawa Tadashi Iida Yasuyuki Mizutani Naomi Kakushima Takuya Ishikawa Kazuhiro Furukawa Eizaburo Ohno Takashi Honda Hiroki Kawashima Masatoshi Ishigami Satoshi Furune Tetsunari Hase Kenji Yokota Osamu Maeda Naozumi Hashimoto Masashi Akiyama Yuichi Ando Mitsuhiro Fujishiro | 2021 | World Journal of Gastroenterology2021，27，41： | 0 |
| 9 | Diagnostic performance of endoscopic classifications for neoplastic lesions in patients with ulcerative colitis:A retrospective casecontrol study显示文摘BACKGROUND It is unclear whether the Japan Narrow-Band Imaging Expert Team(JNET)classification and pit pattern classification are applicable for diagnosing neoplastic lesions in patients with ulcerative colitis(UC).AIM To clarify the diagnostic performance of these classifications for neoplastic lesions in patients with UC.METHODS This study was conducted as a single-center,retrospective case-control study.Twenty-one lesions in 19 patients with UC-associated neoplasms(UCAN)and 23 lesions in 22 UC patients with sporadic neoplasms(SN),evaluated by magnifying image-enhanced endoscopy,were retrospectively and separately assessed by six endoscopists(three experts,three non-experts),using the JNET and pit pattern classifications.The results were compared with the pathological diagnoses to evaluate the diagnostic performance.Inter-and intra-observer agreements were calculated.RESULTS In this study,JNET type 2 A and pit pattern typeⅢ/Ⅳwere used as indicators of low-grade dysplasia,JNET type 2 B and pit pattern typeⅥlow irregularity were used as indicators of highgrade dysplasia to shallow submucosal invasive carcinoma,JNET type 3 and pit pattern typeⅥhigh irregularity/VN were used as indicators of deep submucosal invasive carcinoma.In the UCAN group,JNET type 2 A and pit pattern typeⅢ/Ⅳhad a low positive predictive value(PPV;50.0%and 40.0%,respectively);however,they had a high negative predictive value(NPV;94.7%and 100%,respectively).Conversely,in the SN group,JNET type 2 A and pit pattern typeⅢ/Ⅳhad a high PPV(100%for both)but a low NPV(63.6%and 77.8%,respectively).In both groups,JNET type 3 and pit pattern typeⅥ-high irregularity/VN showed high specificity.The interobserver agreement of JNET classification and pit pattern classification for UCAN among experts were 0.401 and 0.364,in the same manner for SN,0.666 and 0.597,respectively.The intra-observer agreements of JNET classification and pit pattern classification for UCAN among experts were 0.387,0.454,for SN,0.803 and 0.567,respectively.CONCLUSION The accuracy of endoscopic diagnosis using both classifications was lower for UCAN than for SN.Endoscopic diagnosis of UCAN tended to be underestimated compared with the pathological results. | Yuichi Kida Takeshi Yamamura Keiko Maeda Tsunaki Sawada Eri Ishikawa Yasuyuki Mizutani Naomi Kakushima Kazuhiro Furukawa Takuya Ishikawa Eizaburo Ohno Hiroki Kawashima Masanao Nakamura Masatoshi Ishigami Mitsuhiro Fujishiro | 2022 | World Journal of Gastroenterology2022，28，10： | 0 |

| 11 | Mechanism of gastrointestinal abnormal motor activity induced by cisplatin in conscious dogs显示文摘AIM: To investigate whether 5-hydroxytryptamine(serotonin; 5-HT) is involved in mediating abnormal motor activity in dogs after cisplatin administration.METHODS: After the dogs had been given a 2-wk recovery period, all of them were administered cisplatin, and the motor activity was recorded using strain gauge force transducers. Blood and intestinal fluid samples were collected to measure 5-HT for 24 h. To determine whether 5-HT in plasma or that in intestinal fluids is more closely related to abnormal motor activity we injected 5-HT into the bloodstream and the intestinal tract of the dogs.RESULTS: Cisplatin given intravenously produced abnormal motor activity that lasted up to 5 h. From 3 to 4 h after cisplatin administration, normal intact dogs exhibited retropropagation of motor activity accompanied by emesis. The concentration of 5-HT in plasma reached the peak at 4 h, and that in intestinal fluids reached the peak at 3 h. In normal intact dogs with resection of the vagus nerve that were administered kytril, cisplatin given intravenously did not produce abnormal motor activity. Intestinal serotonin administration did not produce abnormal motor activity, but intravenous serotonin administration did.CONCLUSION: After the intravenous administration of cisplatin, abnormal motor activity was produced in the involved vagus nerve and in the involved serotonergic neurons via another pathway. This study was the first to determine the relationship between 5-HT and emesis-induced motor activity. | Hiroyuki Ando Erito Mochiki Tetsuro Ohno Mitsuhiro Yanai Yoshitaka Toyomasu Kyoichi Ogata Yuichi Tabe Ryuusuke Aihara Toshihiro Nakabayashi Takayuki Asao Hiroyuki Kuwano | 2014 | World Journal of Gastroenterology2014，20，42： | 0 |
