11Acute 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 2019World Journal of Gastrointestinal Endoscopy2019,11,3:15

16Control of combustion area using electrical resistivity method for underground coal gasification显示文摘Underground coal gasification (UCG) is one of the clean technologies to collect heat energy and gases (hydrogen, methane, etc.) in an underground coal seam. It is necessary to further developing environ-mentally friendly UCG system construction. One of the most important UCG's problems is underground control of combustion area for efficient gas production, estimation of subsidence and gas leakage to the surface. For this objective, laboratory experiments were conducted according to the UCG model to identify the process of combustion cavity development by monitoring the electrical resistivity activity on the coal samples to setup fundamental data for the technology engineering to evaluate combustion area. While burning coal specimens, that had been sampled from various coal deposits, electrical resistivity was monitored. Symmetric four electrodes system (ABMN) of direct and low-frequency current electric resistance method was used for laboratory resistivity measurement of rock samples. Made research and the results suggest that front-end of electro conductivity activity during heating and combusting of coal specimen depended on heating temperature. Combusting coal electro conductivity has complicated multistage type of change. Electrical resistivity method is expected to be a useful geophysical tool to for evaluation of combustion volume and its migration in the coal seam.Selivanova Tatiana Grebenyuk Igor Belov Alexey 2012International Journal of Mining Science and Technology2012,22,3:11
17Video capsule endoscopy vs double-balloon enteroscopy in the diagnosis of small bowel bleeding:A systematic review and metaanalysis显示文摘AIM To compare the diagnostic accuracy of video capsule endoscopy(VCE) and double-balloon enteroscopy(DBE) in cases of obscure gastrointestinal bleeding(OGIB) of vascular origin.METHODS MEDLINE(via PubMed), LILACS(via BVS) and Cochrane/CENTRAL virtual databases were searched for studies dated before 2017. We identified prospective and retrospective studies, including observational, cohort, single-blinded and multicenter studies, comparing VCE and DBE for the diagnosis of OGIB, and data of all the vascular sources of bleeding were collected. All patients were subjected to the same gold standard method. Relevant data were then extracted from each included study using a standardized extraction form. We calculated study variables(sensitivity, specificity, prevalence, positive and negative predictive values and accuracy) and performed a meta-analysis using Meta-Disc software.RESULTS In the per-patient analysis, 17 studies(1477 lesions) were included. We identified3150 exams(1722 VCE and 1428 DBE) in 2043 patients and identified 2248 sources of bleeding, 1467 of which were from vascular lesions. Of these lesions, 864(58.5%) were diagnosed by VCE, and 613(41.5%) were diagnosed by DBE. The pretest probability for bleeding of vascular origin was 54.34%. The sensitivity of DBE was 84%(95%CI: 0.82-0.86; heterogeneity: 78.00%), and the specificity was92%(95%CI: 0.89-0.94; heterogeneity: 92.0%). For DBE, the positive likelihood ratio was 11.29(95%CI: 4.83-26.40; heterogeneity: 91.6%), and the negative likelihood ratio was 0.20(95%CI: 0.15-0.27; heterogeneity: 67.3%). Performing DBE after CE increased the diagnostic yield of vascular lesion by 7%, from 83% to90%.CONCLUSION The diagnostic accuracy of detecting small bowel bleeding from a vascular source is increased with the use of an isolated video capsule endoscope compared with isolated DBE. However, concomitant use increases the detection rate of the bleeding source.Hélcio Pedrosa Brito Igor Braga Ribeiro Diogo Turiani Hourneaux de Moura Wanderley Marques Bernardo Dalton Marques Chaves Rogério Kuga Ethan Dwane Maahs Robson Kiyoshi Ishida Eduardo Turiani Hourneaux de Moura Eduardo Guimaraes Hourneaux de Moura 2018World Journal of Gastrointestinal Endoscopy2018,10,12:10
18Management of gastroesophageal reflux disease: Patient and physician communication challenges and shared decision making显示文摘Gastroesophageal reflux disease(GERD) is a common upper esophageal condition and typical symptoms can include heartburn and sensation of regurgitation while atypical symptoms include chronic cough, asthma, hoarseness, dyspepsia and nausea. Typically, diag-nosis is presumptive given the presence of typical and atypical symptoms and is an indication for empiric therapy. Treatment management can include lifestyle modifications and/or medication therapy with proton pump inhibitor(PPI) class being the preferred and most effective. Complete symptom resolution is not always achieved and long-term PPI therapy can put patients at risk for serious side effects and needless expense. The brain-gut connection and hypervigilance plays an important role in symptom resolution and treatment success, especially in the case of non-PPI responders. Hypervigilance is a combination of increased esophageal sensory sensitivity in combination with exaggerated threat perception surrounding esophageal symptoms. Hypervigilance requires a different approach to GERD managements, where continued PPI therapy and surgery are usually not recommended. Rather, helping physicians and patients understand the brain-gut connection can guide and improve care.Education and reassurance should be the main pillars or treatment. However, it is important not to suggest the symptoms are due to anxiety alone, this often leads to patient dissatisfaction. Patient dissatisfaction with treatment reveals the need for a more patient-centered approach to GERD management and better communication between patients and providers. Shared decision making(SDM) with the incorporation of patient-reported outcomes(PRO) promotes patient adherence and satisfaction. SDM is a joint discussion between clinician and patient in which a mutually shared solution is explored for GERD symptoms. For SDM to work the physician needs to capture patients' perceptions which may not be obtained in the standard interview. This can be done through the use of PROs which promote a dialogue with patients about their symptoms and treatment priorities in the context of the SDM patient encounter. SDM could potentially help in the management of patient expectations for GERD treatment, ultimately positively impacting their health-related quality of life.Scott Klenzak Igor Danelisen Grace D Brannan Melissa A Holland Miranda AL van Tilburg 2018World Journal of Clinical Cases2018,6,15:10
19Endoscopic papillectomy: Data of a prospective observational study显示文摘AIM:To investigate the clinical value of endoscopic papillectomy indicated by feasibility and safety of the procedure in various diseases of the papilla in a representative number of patients in a setting of daily clinical and endoscopic practice and care by means of a systematic prospective observational study. METHODS:Through a defined time period, all consecutive patients with tumor-like lesions of the papilla, who were considered for papillectomy, were enrolled in this systematic bicenter prospective observational study, and subdivided into 4 groups according to endoscopic and endoscopic ultrasonography (EUS) findings as well as histopathological diagnosis:adenoma; carcinoma/ neuroendocrine tumor (NET)/lymphoma; papilla into which catheter can not be introduced; adenomyomatosis, respectively. Treatment results and outcome were characterized by R0 resection, complication, recurrence rates and tumor-free survival.RESULTS:Over a 7-year period, 58 patients underwent endoscopic papillectomy. Main symptoms prompting to diagnostic measures were unclear abdominal pain in 50% and cholestasis with and without pain in 44%. Overall, 54/58 patients [inclusion rate, 93.1%; sex ratio, males/females = 25/29 (1:1.16); mean age, 65 (range, 22-88) years] were enrolled in the study. Prior to papillectomy, EUS was performed in 79.6% (n = 43/54). Group 1 (adenoma, n = 24/54; 44.4%):91.6% (n = 22/24) with R0 resection; tumor-free survival after a mean of 18.5 mo, 86.4% (n = 19/22); recurrence, 13.6% (n = 3/22); minor complications, 12.5% (n = 3/24). Group 2 (carcinoma/NET/lymphoma, n = 18/54; 33.3%):75.0% (n = 10/18) with R0 resection; tumor-free survival after a mean of 18.5 (range, 1-84) mo, 88.9% (n = 8/9); recurrence, 11.1% (n = 1/9). Group 3 (adenomyomatosis, n = 4/54; 7.4%). Group 4 (primarily no introducible catheter into the papilla, n = 8; 14.8%). The overall complication rate was 18.5% (n = 10/54; 1 subject with 2 complications):Bleeding, n = 3; pancreatitis, n = 7; perforation, n = 1 (intervention-related mortality, 0%). In summary, EUS is a sufficient diagnostic tool to preoperatively clarify diseases of the papilla including suspicious tumor stage in conjunction with postinterventional histopathological investigation of a specimen. Endoscopic papillectomy with curative intention is a feasible and safe approach to treat adenomas of the papilla. In high-risk patients with carcinoma of the papilla with no hints of deep infiltrating tumor growth, endoscopic papillectomy can be considered a reasonable treatment option with low risk and an approximately 80% probability of no recurrence if an R0 resection can be achieved. In patients with jaundice and in case the catheter can not be introduced into the papilla, papillectomy may help to get access to the bile duct. CONCLUSION:Endoscopic papillectomy is a challenging interventional approach but a suitable patientand local finding-adapted diagnostic and therapeutic tool with adequate risk-benefit ratio in experienced hands.Uwe Will Anne-Kathrin Müller Frank Fueldner Igor Wanzar Frank Meyer 2013World Journal of Gastroenterology2013,19,27:10
