| 1 | Feasibility and safety of autologous bone marrow mononuclear cell transplantation in patients with advanced chronic liver disease显示文摘AIM: To evaluate the safety and feasibility of bone marrow cell (BMC) transplantation in patients with chronic liver disease on the waiting list for liver transplantation. METHODS: Ten patients (eight males) with chronic liver disease were enrolled to receive infusion of autologous bone marrow-derived cells. Seven patients were classified as Child-Pugh B and three as Child-Pugh C. Baseline assessment included complete clinical and laboratory evaluation and abdominal MRI. Approximately 50 ml of bone marrow aspirate was prepared by centrifugation in a ficoll-hypaque gradient. At least of 100 millions of mononuclear-enriched BMCs were infused into the hepatic artery using the routine technique for arterial chemoembolization for liver tumors. Patients were followed up for adverse events up to 4 mo. RESULTS: The median age of the patients was 52 years (range 24-70 years). All patients were discharged 48 h after BMC infusion. Two patients complained ofmild pain at the bone marrow needle puncture site. No other complications or specific side effects related to the procedure were observed. Bilirubin levels were lower at 1 (2.19 ± 0.9) and 4 mo (2.10 ± 1.0) after cell transplantation that baseline levels (2.78 ± 1.2). Albumin levels 4 mo after BMC infusion (3.73 ± 0.5) were higher than baseline levels (3.47 ± 0.5). International normalized ratio (INR) decreased from 1.48 (SD = 0.23) to 1.43 (SD = 0.23) one month after cell transplantation. CONCLUSION: BMC infusion into hepatic artery of patients with advanced chronic liver disease is safe and feasible. In addition, a decrease in mean serum bilirubin and INR levels and an increase in albumin levels are observed. Our data warrant further studies in order to evaluate the effect of BMC transplantation in patients with advanced chronic liver disease. | Andre Castro lyra Milena Botelho Pereira Soares luiz Flavio Maia da Silva Marcos Fraga Fortes André Goyanna Pinheiro Silva Augusto César de Andrade Mota Sheilla A Oliveira Eduardo lorens Braga Wilson Andrade de Carvalho Bernd Genser Ricardo Ribeiro dos Santos luiz Guilherme Costa lyra | 2007 | World Journal of Gastroenterology2007，13，7： | 21 |
| 2 | Acute abdominal obstruction:Colon stent or emergency surgery? An evidence-based review显示文摘According to the American Cancer Society and Colorectal Cancer Statistics 2017,colorectal cancer(CRC) is one of the most common malignancies in the United States and the second leading cause of cancer death in the world in 2018.Previous studies demonstrated that 8%-29% of patients with primary CRC present malignant colonic obstruction(MCO). In the past, emergency surgery has been the primary treatment for MCO, although morbidity and surgical mortality rates are higher in these settings than in elective procedures. In the 1990 s, selfexpanding metal stents appeared and was a watershed in the treatment of patients in gastrointestinal surgical emergencies. The studies led to high expectations because the use of stents could prevent surgical intervention, such as colostomy, leading to lower morbidity and mortality, possibly resulting in higher quality of life. This review was designed to provide present evidence of the indication, technique, outcomes, benefits, and risks of these treatments in acute MCO through the analysis of previously published studies and current guidelines. | Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura Christopher C Thompson Eduardo Guimaraes Hourneaux de Moura | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，3： | 15 |
| 3 | Role of endoscopic vacuum therapy in the management of gastrointestinal transmural defects显示文摘A gastrointestinal(GI) transmural defect is defined as total rupture of the GI wall,and these defects can be divided into three categories: perforations,leaks,and fistulas. Surgical management of these defects is usually challenging and may be associated with high morbidity and mortality rates. Recently,several novel endoscopic techniques have been developed,and endoscopy has become a firstline approach for therapy of these conditions. The use of endoscopic vacuum therapy(EVT) is increasing with favorable results. This technique involves endoscopic placement of a sponge connected to a nasogastric tube into the defect cavity or lumen. This promotes healing via five mechanisms,including macrodeformation,microdeformation,changes in perfusion,exudate control,and bacterial clearance,which is similar to the mechanisms in which skin wounds are treated with commonly employed wound vacuums. EVT can be used in the upper GI tract,small bowel,biliopancreatic regions,and lower GI tract,with variable success rates and a satisfactory safety profile. In this article,we review and discuss the mechanism of action,materials,techniques,efficacy,and safety of EVT in the management of patients with GI transmural defects. | Diogo Turiani Hourneaux de Moura Bruna Furia Buzetti Hourneaux de Moura Michael A Manfredi Kelly E Hathorn Ahmad N Bazarbashi Igor Braga Ribeiro Eduardo Guimaraes Hourneaux de Moura Christopher C Thompson | 2019 | World Journal of Gastrointestinal Endoscopy2019，11，5： | 6 |
| 4 | Relationship between Th17 immune response and cancer显示文摘Cancer is the second leading cause of death worldwide and epidemiological projections predict growing cancer mortality rates in the next decades.Cancer has a close relationship with the immune system and,although Th17 cells are known to play roles in the immune response against microorganisms and in autoimmunity,studies have emphasized their roles in cancer pathogenesis.The Th17 immune response profile is involved in several types of cancer including urogenital,respiratory,gastrointestinal,and skin cancers.This type of immune response exerts pro and antitumor functions through several mechanisms,depending on the context of each tumor,including the protumor angiogenesis and exhaustion of T cells and the antitumor recruitment of T cells and neutrophils to the tumor microenvironment.Among other factors,the paradoxical behavior of Th17 cells in this setting has been attributed to its plasticity potential,which makes possible their conversion into other types of T cells such as Th17/Treg and Th17/Th1 cells.Interleukin(IL)-17 stands out among Th17-related cytokines since it modulates pathways and interacts with other cell profiles in the tumor microenvironment,which allow Th17 cells to prevail in tumors.Moreover,the IL-17 is able to mediate pro and antitumor processes that influence the development and progression of various cancers,being associated with variable clinical outcomes.The understanding of the relationship between the Th17 immune response and cancer as well as the singularities of carcinogenic processes in each type of tumor is crucial for the identification of new therapeutic targets. | Hanna Santos Marques Breno Bittencourt de Brito Filipe Antônio França da Silva Maria Luísa Cordeiro Santos Júlio César Braga de Souza Thiago Macêdo Lopes Correia Luana Weber Lopes Nayara Silva de Macêdo Neres Rafael Santos Dantas Miranda Dórea Anna Carolina Saúde Dantas Lorena Lôbo Brito Morbeck Iasmin Souza Lima Amanda Alves de Almeida Maiara Raulina de Jesus Dias Fabrício Freire de Melo | 2021 | World Journal of Clinical Oncology2021，12，10： | 5 |

| 7 | Acute bleeding after argon plasma coagulation for weight regain after gastric bypass: A case report显示文摘Roux-en-Y gastric bypass(RYGB)is the most commonly performed surgical procedure used to treat obesity worldwide.Despite satisfactory results in terms of weight loss,over time many patients experience weight regain.There are many factors that contribute to weight regain after RYGB,including the diameter of the gastric-jejunal anastomosis(GJA).One of the most commonly performed endoscopic procedures for weight regain after RYGB is argon plasma coagulation(APC).We report a case of hematemesis after outlet revision with APC.We highlight several treatment modalities that can be used to treat this complication.CASE SUMMARY A 45-year-old female with a history of weight regain after RYGB was referred for possible endoscopic treatment for weight regain.On endoscopic evaluation,the diameter of the GJA was 22 mm.Due to the dilated GJA,treatment with APC was performed.Several months later she reported a return of poor satiety and an increased appetite.A repeat endoscopy was then performed.The GJA was approximately 15 mm and was incompetent.APC was performed.One day post procedure she had four episodes of hematemesis.An endoscopy was performed and a large ulcer with a visible arterial vessel was visualized at the GJA.Coagulation was attempted using a Coagrasper and after initial contact with the vessel,the vessel started oozing.Due to fibrosis and the depth of ulceration in the area,clips and repeat APC could not be used.Therefore,an attempt to inject epinephrine injection was made.However,persistent oozing was noted.As a result,hemostatic powder was applied to the region of the bleeding vessel.Subsequently,no more bleeding was observed.On follow-up,the patient remained hemodynamically stable and a second look endoscopy was not performed.The patient was discharged three days later.CONCLUSION APC revision of the GJA is known to be a relatively safe and effective strategy to manage weight regain post RYGB.Anastomotic site bleeding is an infrequent and potentially life-threatening complication associated with this therapy.Endoscopic management is the first line therapy used to achieve hemostasis in these cases. | Diogo Turiani Hourneaux de Moura Amit H Sachdev Po-Wen Lu Igor Braga Ribeiro Christopher C Thompson | 2019 | World Journal of Clinical Cases2019，7，15： | 1 |
