Endoscopic colonic stenting with self-expandable metal stents (SEMS) is considered to be a promising way to treat such patients. However, its capabilities are not yet fully explored. This paper presents a cross-sectional study of the results of endoscopic colonic stenting using SEMS in AMCO patients, performed in 2016 - 2020.Objective: to clarify the outcomes of endoscopic stenting with SEMS in AMCO patients and identify the factors that influence its result.Materials and Methods. The study included 218 patients with AMCO in whom surgeons made an attempt to eliminate the acute colonic obstruction using the method of endoscopic stenting. The capabilities of endoscopic stenting were assessed on the basis of calculated technical and clinical efficacy, the incidence of complications and mortality. To identify the factors that can predict the outcome of a stenting attempt, all patients were divided into two groups: a group of clinical success (182 patients) and a group of clinical failure (36 patients). The groups were subjected to comparative analysis.Results. The analysis of the obtained results registered that the technical efficiency of endoscopic stenting of the colon is 91.7% and its clinical efficiency is 83.5%, the incidence of intra-abdominal complications is 8.3%, the incidence of somatic complications is 11.9%, the mortality is 5%. Comparative analysis of the groups revealed differences (with p <0.05) for the oncological process stage, the duration and the severity of intestinal obstruction. Conclusion. Endoscopic stenting of the colon with SEMS is an effective way to treat patients with AMCO. Its success can vary depending on the severity of trophic disorders in the intestinal wall.","PeriodicalId":23249,"journal":{"name":"Trauma monthly","volume":"27 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-08-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90063214","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Extended focused assessment with sonography for trauma (e-FAST) is one of the diagnostic methods for hemothorax assessment. However, there are still limited data about its diagnostic value, especially in determining the size of the hemothorax. Objective: This study aimed to assess the diagnostic value of e-FAST in detecting hemothorax and determining its size among patients with blunt thoracic trauma. Methods: This cross-sectional diagnostic assessment study was conducted on 400 adult patients with blunt trauma who needed chest CT-scan. Chest X-ray (CXR), sonography and chest CT-scan were performed and hemothorax size was assessed with sonography and CT-scan. Sensitivity, specificity, and positive and negative predictive values of sonography and CXR were calculated. Hemothorax size on sonography was compared with the results of CT-scan as gold standard. Findings: Mean age of participants was 43.67±22.03. Based on CT-scan findings, 176 participants (44%) had a hemothorax. The sensitivity, specificity, positive and negative predictive values, and correct classification rate of sonography were 79%, 99.1%, 98.6%, 85.7%, and 90.2%, respectively. Sonography detected accurately 97.1% of small hemothoraxes, 46.9% of medium hemothoraxes and 33.3% of large hemothoraxes. Conclusion: Sonography is a sensitive diagnostic modality for the detection of hemothorax in multiple trauma patients, but tends to underestimate moderate to large sized hemothoraxes. Chest sonography can be an acceptable imaging modality, if CT-scan is not available or desired.","PeriodicalId":23249,"journal":{"name":"Trauma monthly","volume":"55 1","pages":""},"PeriodicalIF":0.5,"publicationDate":"2021-07-13","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80065905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, there are still many challenges to choose the best choice. Minimally-invasive techniques such as ozone therapy are emerging choices for surgery.Objective: We evaluated the effects of ozone therapy on patients with LBP with protruding disc herniation who failed to respond to medical treatment.Methods: In this Randomized phase III clinical trial (2017-19), one hundred patients admitted to Imam Reza Hospital (Tabriz-Iran) for herniated disk-induced LBP were randomly divided (shape- and color-identical envelopes) into two case and control groups. Patients in the case group were treated with ozone therapy (25 mcg/mL in 5 cc volume) plus medical therapy (naproxen 500 mg and baclofen 10 mg, both two times a day). Alternatively, patients in the control group received only conventional medical therapy. Primary outcomes such as changes in pain intensity (VAS) and basal test before and after treatment and also secondary outcomes like the amount of analgesic used were evaluated in the patients during two weeks, three months and six months after surgery. Student T-test and Chi-square were compared for comparing the data.Results: Mean pain intensities estimated by VAS and improvement of restless leg syndrome were not significantly different between the two groups during two weeks (p =0.8), three months (p =0.5) and six months (p =0.9) after the intervention. Pain intensity was found to be lower in both groups after the intervention compared with before treatment (p =0.001 for both). Moreover, significant differences were found between two groups in the Lasegue test during two weeks (p =0.02) and six months (p =0.01) after the intervention.Conclusion: Application of ozone therapy not only improves clinical pain syndrome in LBP patients but also leads to improved medical treatment in these patients.","PeriodicalId":23249,"journal":{"name":"Trauma monthly","volume":"1 1","pages":"206-212"},"PeriodicalIF":0.5,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89788003","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bone loss in such fractures adds to the complexity. Conventional techniques of bone defect management are mainly directed toward fracture union but not against preventing infection or joint stiffness.Objectives: In this study, we evaluated Masquelet's technique for the management of open distal end Femur fractures with bone loss.Methods: Twenty-two patients with open distal end fractures with bone defects who presented within 3 days of trauma from January 2015 to December 2018, treated by the Masquelet's technique are included in this study. All the patients were operated on by the same surgeon. All the patients were taken up for the first stage of surgery immediately after the presentation. Details of the type of injury, location, soft-tissue condition, length of bone defect, type of fixation, the time difference between antibiotic cement spacer placement and bone grafting, and time to the union were documented.Results: Fractures with Type IV bone loss (segmental loss) united slower than fractures having some cortical continuity (Type II and III), P=0.003. In Type IV, the bone loss average time to union was 316.6±44.5 days, whereas, in Type III and II, it was 240±30 and 180, respectively. In the first stage, internal fixation with antibiotics cement spacer was done in all cases. In patients with internal fixation with 2nd stage spacer removal plus bone grafting done, time to union was 244.1±42.9 days. No patients had an infection after the first stage of surgery.Conclusion: The technique of delayed bone grafting after the initial placement of a cement spacer provides a reasonable alternative for the challenging problem of significant bone loss in extremity reconstruction. This technique can be used in either an acute or delayed fashion with equally promising results. The bioactivity of the membrane created by filling large bony defects with cement leads to a favorable environment for bone formation and osseous consolidation of a large void. As this technique becomes more widely applied, the answer to which graft substances to place in the void may become clearer. Increasing clinical evidence will also help support the use of this technique in treating segmental bone loss.","PeriodicalId":23249,"journal":{"name":"Trauma monthly","volume":"2017 1","pages":"213-221"},"PeriodicalIF":0.5,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75415218","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
