BackgroundAcute appendicitis (AA) is the most common surgical disease, and appendectomy is the treatment of choice in the majority of cases. A correct diagnosis is key for decreasing the negative appendectomy rate. The management can become difficult in case of complicated appendicitis. The aim of this study is to describe the worldwide clinical and diagnostic work-up and management of AA in surgical departments.MethodsThis prospective multicenter observational study was performed in 116 worldwide surgical departments from 44 countries over a 6-month period (April 1, 2016–September 30, 2016). All consecutive patients admitted to surgical departments with a clinical diagnosis of AA were included in the study.ResultsA total of 4282 patients were enrolled in the POSAW study, 1928 (45%) women and 2354 (55%) men, with a median age of 29 years. Nine hundred and seven (21.2%) patients underwent an abdominal CT scan, 1856 (43.3%) patients an US, and 285 (6.7%) patients both CT scan and US. A total of 4097 (95.7%) patients underwent surgery; 1809 (42.2%) underwent open appendectomy and 2215 (51.7%) had laparoscopic appendectomy. One hundred eighty-five (4.3%) patients were managed conservatively. Major complications occurred in 199 patients (4.6%). The overall mortality rate was 0.28%.ConclusionsThe results of the present study confirm the clinical value of imaging techniques and prognostic scores. Appendectomy remains the most effective treatment of acute appendicitis. Mortality rate is low.
Background Timing and adequacy of peritoneal source control are the most important pillars in the management of patients with acute peritonitis. Therefore, early prognostic evaluation of acute peritonitis is paramount to assess the severity and establish a prompt and appropriate treatment. The objectives of this study were to identify clinical and laboratory predictors for in-hospital mortality in patients with acute peritonitis and to develop a warning score system, based on easily recognizable and assessable variables, globally accepted. Methods This worldwide multicentre observational study included 153 surgical departments across 56 countries over a 4-month study period between February 1, 2018, and May 31, 2018. Results A total of 3137 patients were included, with 1815 (57.9%) men and 1322 (42.1%) women, with a median age of 47 years (interquartile range [IQR] 28–66). The overall in-hospital mortality rate was 8.9%, with a median length of stay of 6 days (IQR 4–10). Using multivariable logistic regression, independent variables associated with in-hospital mortality were identified: age > 80 years, malignancy, severe cardiovascular disease, severe chronic kidney disease, respiratory rate ≥ 22 breaths/min, systolic blood pressure < 100 mmHg, AVPU responsiveness scale (voice and unresponsive), blood oxygen saturation level (SpO 2 ) < 90% in air, platelet count < 50,000 cells/mm3, and lactate > 4 mmol/l. These variables were used to create the PIPAS Severity Score, a bedside early warning score for patients with acute peritonitis. The overall mortality was 2.9% for patients who had scores of 0–1, 22.7% for those who had scores of 2–3, 46.8% for those who had scores of 4–5, and 86.7% for those who have scores of 7–8. Conclusions The simple PIPAS Severity Score can be used on a global level and can help clinicians to identify patients at high risk for treatment failure and mortality.
Traumatic injuries of the extrahepatic biliary tract are rare. Associated injuries are usually responsible for immediate indication for surgical treatment, the time when an injury to the extrahepatic biliary ducts may be diagnosed. However, missed injuries are often common. The primary aim of this paper is to describe the clinical features, diagnosis, treatment, and outcome of two patients with left hepatic duct injury after blunt abdominal trauma. As a secondary objective, a literature review is presented. The two cases presented in this study are as follows: (1) A young male, involved in a motor vehicle crash, was admitted with blunt hepatic trauma in a general hospital. Endoscopic retrograde cholangiography was conducted 3 weeks later and revealed a large leakage at the left hepatic duct. Exploratory laparotomy was performed 26 days after the initial traumatic event and identified a complete section of the left hepatic duct, treated with anastomosis. (2) A male fell from a height. On exploratory laparotomy, a 30 % partial injury of the left hepatic duct was found in addition to hemoperitoneum, liver injury, gallbladder detachment together with cystic duct rupture, retroperitoneal hematoma to the right, and cecum hematoma. A high level of suspicion is necessary to identify injuries to the hepatic ducts. Early diagnosis that occurs during laparotomy due to associated injuries is important to reduce complications.
Objective: to identify predictors of chest drainage complications in trauma patients attended at a University Hospital. Methods: we conducted a retrospective study of 68 patients submitted to thoracic drainage after trauma, in a one-year period. We analyzed gender, age, trauma mechanism, trauma indices, thoracic and associated lesions, environment in which the procedure was performed, drainage time, experience of the performer, complications and evolution. Results: the mean age of the patients was 35 years and the male gender was the most prevalent (89%). Blunt trauma was the most frequent, with 67% of cases, and of these, 50% were due to traffic accidents. The mean TRISS (Trauma and Injury Severity Score) was 98, with a mortality rate of 1.4%. The most frequent thoracic and associated lesions were, respectively, rib fractures (51%) and abdominal trauma (32%). The mean drainage time was 6.93 days, being higher in patients under mechanical ventilation (p=0.0163). The complication rate was 26.5%, mainly poor drain positioning (11.77%). Hospital drainage was performed in 89% of cases by doctors in the first year of specialization. Thoracic drainage performed in prehospital care presented nine times more chances of complications (p=0.0015). Conclusion: the predictors of post-trauma complications for chest drainage were a procedure performed in an adverse site and mechanical ventilation. The high rate of complications demonstrates the importance of protocols of care with the thoracic drainage.
OBJETIVO: É estabelecer um modelo experimental de choque hemorrágico, reproduzindo o mais próximo possível uma real situação que ocorre nas vítimas traumatizadas. MÉTODOS: Utilizou-se 16 animais, distribuídos aleatoriamente em 2 grupos (n=8): Grupo Controle (GC): procedimentos cirúrgicos e observação de 60 minutos; Grupo Choque (GCh): procedimentos cirúrgicos, sangria para estabelecimento do estado de choque (EC) com pressão arterial média (PAM) em 40 mmHg, mantido por 20 minutos (20') seguido de período de reperfusão de 60 minutos (RP60). Para avaliar o EC estabelecido, além da PAM, utilizaram-se os seguintes parâmetros: lactato sérico (LS) e diferença de base (DB). Na instalação do EC, iniciou-se com retirada de volume de sangue correspondente a 5% da volemia estimada até atingir PAM de 60mmHg, ponto do qual as retiradas passaram para 2,5%. RESULTADOS: Após o período de 20' do EC o LS médio do GC foi de 0,92 mmol/l e do GCh foi de 4,16 mmol/l. A DB média do GC foi de 0,02 mmol/l e do GCh foi de 8, 12 mmol/l. CONCLUSÃO: As alterações resultantes do processo de instalação e reanimação do EC mostraram uma relação inversamente proporcional entre LS e DB, fato que confirma a má perfusão tecidual e restauração volêmica dentro do presente modelo experimental.
A non-operative approach resulted in lower complications, a lower need for blood transfusions and lower mortality.
RESUMO Objetivo: caracterizar o perfil dos potenciais e dos efetivos doadores de órgãos, e identificar os fatores relacionados a não efetivação da doação. Métodos: estudo retrospectivo transversal com coleta de dados das fichas da Organização de Procura de Órgãos do Hospital das Clínicas da Unicamp, referente ao período de janeiro de 2013 a abril de 2018. Resultados: o estudo contou com 1.772 potenciais doadores; predominou-se o sexo masculino (57,39%) e o evento vascular (n=996) foi a principal causa de morte encefálica. A recusa familiar (42,8%) foi o motivo mais comum para não doação de órgãos. Houve diferença estatística entre doadores e não doadores quanto à média de idade e pressão arterial sistólica, assim como houve relação entre a doação de órgãos e a ausência de diabetes e tabagismo. Conclusão: a maioria dos doadores efetivos foi do sexo masculino e jovem. As principais causas de morte encefálica e de recusa familiar foram, respectivamente, vasculares e não manifestação da vontade de ser doador após a morte. O etilismo foi mais presente nas causas traumáticas, assim como, o sexo masculino. Assim, iniciativas de conscientização populacional e abertura de discussão dentro da família sobre o ato da doação contribuem para o aumento do índice de doadores efetivos.
The study showed that CXR is very useful in the initial diagnostic approach to PTDH. The difficulty is that diaphragmatic injuries, particularly after penetrating trauma, may initially go unnoticed, and without changes in the CXR images, diagnosis is made difficult.
