Endoscopic Management of a Chronic Gastrocutaneous Fistula after Bariatric Revisional Surgery Using a Novel Cardiac Septal Occluder.

Introduction: Endoscopic techniques are now considered the first-line approach for the management of bariatric surgery-related fistulas. The off-label use of cardiac septal defect occluders (CSDO) is an emerging technique that has demonstrated favorable outcomes for the closure of extravascular defects, including gastrointestinal (GI) disruptions. Previous case reports have reported similar results with the CSDO Amplatzer™ for the management of GI disruptions following bariatric surgery. However, the use of similar alternative devices for this purpose has not yet been described. Case Presentation: This case report presents the first reported use of the Occlutech® CSDO for the treatment of a chronic gastrocutaneous fistula after bariatric revisional surgery. Despite apparent initial success - no extravasation of contrast material through the device in the contrast study after the CSDO placement - fistula closure failed due to partial dislodgement of the device. The placement of a second device between the discs of the former one ultimately sealed the fistulous orifice. Discussion: In chronic GI fistulas, the mature tract is often not liable to the application of standard endoscopic methods, leading to failed closure attempts. A new application of Occlutech® CSDO can obviate the clinical burden of a high-risk laparotomy in these cases. Appropriate endoscopic equipment as well as the involvement of a multidisciplinary team are prime conditions to ensure successful patient outcomes.

Introdução: As técnicas endoscópicas são atualmente consideradas abordagens de primeira linha no manejo das fístulas associadas a cirurgia bariátrica. O uso off-label de dispositivos de oclusão do septo cardíaco (CSDO) é uma técnica nova que tem demonstrado resultados favoráveis no encerramento de defeitos extra-vasculares, incluindo fístulas gastrointestinais. Relatos de caso prévios reportaram resultados semelhantes com o CSDO Amplatzer ™ para o tratamento de fístulas gastrointestinais pós cirurgia bariátrica. No entanto, o uso de dispositivos alternativos semelhantes para esse fim ainda não foi descrito. Relato de Caso: Este relato de caso apresenta o primeiro uso reportado do CSDO Occlutech® para tratamento de fístula gastrocutânea crônica após cirurgia bariátrica revisional. Apesar do aparente sucesso inicial ­ nenhum extravasamento de contraste através do dispositivo na fluoroscopia após a colocação do CSDO, houve recorrência da drenagem fistulosa devido ao deslocamento parcial do dispositivo. A colocação de um segundo dispositivo entre os discos do primeiro acabou por encerrar o orifício fistuloso. Discussão: Nas fístulas gastrointestinais crônicas, o trajeto epitelizado muitas vezes não é passível de aplicação dos métodos endoscópicos tradicionais, levando a múltiplas tentativas fracassadas de encerramento. A nova aplicação de Occlutech® CSDO pode evitar o risco de uma laparotomia de alto risco nesses casos. Equipamentos endoscópicos adequados, bem como o envolvimento de equipe multidisciplinar são condições primordiais para garantir o sucesso do tratamento.

Isolated subcutaneous emphysema of the abdominal wall following endoscopic retrograde cholangiopancreatography.

Isolated subcutaneous emphysema without retroperitoneal perforation is a rare complication of endoscopic retrograde cholangiopancreatography (ERCP). We present the case of an 87-year-old female who developed extensive subcutaneous emphysema following ERCP for choledocholithiasis. Abdominal computed tomography showed air perfectly dissecting the abdominal wall muscle layers and no evidence of an air leak in the pleural, mediastinal, or peritoneal spaces.

Impact of COVID-19 Outbreak on the Emergency Presentation of Acute Appendicitis.

BACKGROUND: The global crisis resulting from the coronavirus pandemic has imposed a large burden on health systems worldwide. Nonetheless, acute abdominal surgical emergencies are major causes for nontrauma-related hospital admissions and their incidences were expected to remain unchanged. Surprisingly, a significant decrease in volume and a higher proportion of complicated cases are being observed worldwide. METHODS: The present study assesses the local impact of the coronavirus pandemic on the emergency presentation of acute appendicitis in a Brazilian hospital. A retrospective analysis was conducted on patients undergoing emergency surgery for the clinically suspected diagnosis of acute appendicitis during the 2-month period of March and April 2020 and the same time interval in the previous year. Data on demographics, timing of symptom onset and hospital presentation, intraoperative details, postoperative complications, hospital length of stay, and histological examination of the specimen were retrieved from individual registries. RESULTS: The number of appendectomies during the pandemic was 36, which represents a 56% reduction compared to the 82 patients operated during the same period in 2019. The average time of symptom onset to hospital arrival was significantly higher in 2020 (40.6 vs. 28.2 hours, P = .02). The classification of appendicitis revealed a significant higher proportion of complicated cases than the previous year (33.3% vs. 15.2%, P = .04). The rate of postoperative complications and the average length of stay were not statistically different between the groups. CONCLUSION: Further assessment of patients' concerns and systematic monitoring of emergency presentations are expected to help us understand and adequately address this issue.
