Controversies in the Management of Asymptomatic Patients Sustaining Penetrating Thoracoabdominal Wounds

The most challenging diagnostic issue in the management of thoracoabdominal wounds concerns the assessment of asymptomatic patients. In almost one-third of such cases, diaphragmatic injuries are present even in the absence of any clear clinical signs. The sensitivity of noninvasive diagnostic tests is very low in this situation, and acceptable methods for diagnosis are limited to videolaparoscopy or videothoracoscopy. However, these procedures are performed under general anesthesia and present real, and potentially unnecessary, risks for the patient. On the other hand, diaphragmatic hernias, which can result from unsutured diaphragmatic lesions, are associated with considerable morbidity and mortality. In this paper, the management of asymptomatic patients sustaining wounds to the lower chest is discussed, with a focus on the diagnosis of diaphragmatic injuries and the necessity of suturing them

A Brazilian survey regarding the management of acute pancreatitis

OBJETIVO: Avaliar como a pancreatite aguda é vista e tratada pelo cirurgião brasileiro. MÉTODO: Trata-se de um questionário prospectivo enviado aos membros do Colégio Brasileiro de Cirurgiões (CBC). Dois mil questionários foram enviados obtendo-se 618 respostas (30,9%). O questionário constituía de perguntas relacionadas à experiência do cirurgião e ao tratamento da PA. RESULTADOS: Cento e oitente e dois entrevistados (33,6%) disseram tratar até cinco casos por ano e 147 (27,2%) tratam de seis a 10 casos por ano. Dentre os critérios utilizados para a definição de PA, o mais citado foi a avaliação clínica por 306 (57,4%) entrevistados, seguido dos critérios de Ranson por 294 (55,2%) e TC por 262 (49,2%). Com relação ao uso da TC, 275 (51,5%) entrevistados responderam que realizam a TC em todos os doentes com PA. O suporte nutricional parenteral foi o método de escolha indicado por 248 (46,6%) entrevistados. A infecção da coleção e/ou necrose pancreática é a principal indicação operatória com 447 (83,6%) respostas. O melhor período para operar um doente com PA grave foi considerado até quatorze dias por 278 (54,2%) entrevistados. Com relação aos antibióticos, 371 (68,6%) entrevistados disseram que utilizam antibióticos no tratamento da PA grave. CONCLUSÃO: Estes resultados demonstram uma ampla variação no tratamento da PA no Brasil. A pouca experiência dos cirurgiões e os temas controversos são os fatores principais responsável para esta falta de padronização. A realização de um Consenso nacional baseado nos novos conceitos e na experiência mundial é crucial para ajustar estas condutas.BACKGROUND: to evaluate as AP is managed by the Brazilian surgeon. METHODS: A questionnaire has been sent to 2,000 members of the Brazilian College of Surgeons, with 618 (30.9%) answers obtained. The questionnaire consisted of questions related to the experience of the surgeon and in particular to the treatment of AP. RESULTS: One hundred and eighty-two interviewed (33.6%) answered to treat up to five cases per year and 147 (27.2%) treat six to ten cases per year. The most cited criteria used for the definition of severe AP was clinical evaluation for 306 (57.4%) interviewed, followed by the Ranson criteria for 294 (55.2%) and CT scan for 262 (49.2%). Regarding the use of CT, 275 (51.5%) interviewed answered that make use of CT scan for all patients with AP. The parenteral nutritional support was the method of choice indicated for 248 (46.6%) interviewed. The infection of fluid collection and/or pancreatic necrosis was the main reason for surgical treatment with 447 (83.6%) answers. The optimum period to operate a patient with severe AP was considered up to seven days for 278 (54.2%) interviewed. With relation to antibiotics, 371 (68.6%) said that they use antibiotics in the treatment of severe AP. CONCLUSION: These findings demonstrate a wide variation in the treatment of AP in Brazil. Little experience of the surgeons and controversial issues are the main factors responsible for this lack of standardization. A national Consensus based on new concepts and worldwide experience is crucial to adjust these thoughts

Hernioplastia inguinal segundo procedimento de Stoppa: drenar ou não drenar

OBJETIVO: O objetivo do presente estudo é avaliar os benefícios da drenagem no procedimento de Stoppa no tratamento da hérnia inguinal. PACIENTES E MÉTODOS: O uso da drenagem de aspiração contínua foi randomizado ao final do procedimento cirúrgico em 26 pacientes submetidos à correção da hérnia inguinal e divididos em dois grupos: Grupo A, com 12 pacientes submetidos à drenagem e Grupo B, com 14 pacientes não submetidos à drenagem. No segundo dia de pós-operatório, todos os pacientes foram submetidos à tomografia computadorizada de abdome para a verificação de coleções abdominais. RESULTADOS: No Grupo A, nenhum paciente apresentou coleção no espaço pré-peritonial. Por outro lado, um paciente desenvolveu abcesso no espaço pré-peritonial no décimo quinto dia de pós-operatório. No Grupo B, 12 pacientes apresentaram coleção pré-peritonial à tomografia. Entretanto, somente três apresentaram complicações menores. Nenhum paciente apresentou complicação maior. CONCLUSÃO: O uso de drenagem de aspiração contínua no procedimento de Stoppa não traz nenhum benefício.OBJECTIVE: The objective of this study is to evaluate the benefits of drainage in the Stoppa procedure for inguinal repair. PATIENTS AND METHODS: The use of a suction drain was randomized at the end of the surgical intervention in 26 male patients undergoing inguinal hernia repair, divided into 2 groups: Group A, 12 patients undergoing drainage, and group B, 14 patients not undergoing drainage. On the second postoperative day, all patients underwent abdominal pelvic computed tomography scan examination to detect the presence of abdominal fluid collection. RESULTS: In group A, no patient developed fluid collection in the preperitoneal space, and 1 patient presented with an abscess in the preperitoneal space on the 15th postoperative day. In group B, 12 patients presented with fluid collections in the preperitoneal space on computed tomography scan evaluation. However, only 3 patients presented minor complications. None of the patients developed a major complication. CONCLUSION: The use of suction drainage with the Stoppa procedure does not provide any benefit

Prospective Analysis of Short- and Mid-term Knowledge Retention after a Brief Ultrasound Course for Undergraduate Medical Students

OBJECTIVES: The benefits of implementing point-of-care ultrasound (POCUS) in the emergency department are well established. Ideally, physicians should be taught POCUS during medical school. Several different courses have been designed for that purpose and have yielded good results. However, medical students need specifically designed courses that address the main objectives of knowledge acquisition and retention. Despite that, there is limited evidence to support knowledge retention, especially in the mid-term. The purpose of this study is to evaluate short- and mid-term knowledge retention after a student-aimed ultrasound course. METHODS: Medical students participating in a medical student trauma symposium (SIMPALT) in 2017 were included. Their profiles and baseline ultrasound knowledge were assessed by a precourse questionnaire (PRT). The same questionnaire was used one week (1POT) and three months (3POT) after the course. RESULTS: Most of the participants were 1st- to 4th- year medical students. None had prior ultrasound knowledge. They reported costs as the major barrier (65%) to enrollment in an ultrasound course. A comparison between the PRT and 1POT results showed a statistically significant difference (po0.02), while no difference was found between 1POT and 3POT (p40.09). CONCLUSION: Our findings support the use of a tailored ultrasound course for medical students. Knowledge acquisition and mid-term retention may be achieved by this specific population
