Role of sarcopenia in complex abdominal wall surgery: does it increase postoperative complications and mortality?

12 p.Background: Sarcopenia is defined as the loss of skeletal muscle mass and is associated with an increased risk or morbidity and mortality in complex surgical patient populations. Its role in complex abdominal wall surgery (AWS) is yet to be determined. The aim of this study is to establish if sarcopenia has an impact on postoperative complications, mortality and hernia recurrence. Methods: Retrospective study of patients undergoing elective surgery for complex incisional hernias > 10 cm (W3 of European Hernia Society classification) between 2014-2023. Sarcopenia was stablished as the skeletal muscle index (SMI), measured at L3 transversal section of a preoperative CT-scan. Previously defined literature-based SMI cutoff values were used: men ? 52.4 cm2/m2, women ? 38.5 cm2/m2. Results: 135 patients undergoing complex AWS were included. Of them, 38 were sarcopenic (28.1%). The median follow-up time was 13 months (IQR 12-25). In total, 11 patients died (8.1%). We found that sarcopenia was associated with a higher risk of mortality [HR 7.494 (95% CI 1.985-28.289); p 0.003]. There were no statistically significant differences in postoperative complications or hernia recurrence between both groups. Conclusion: Although sarcopenia does not seem to have an influence on hernia recurrence or the development of postoperative complications, whether local or systemic, in our study sarcopenia is associated with a higher risk of mortality after complex abdominal wall surgery. Nonetheless, with the results obtained in our study, we think that prehabilitation programs before complex AWS is advisable

Morgagni Hernia Repair in Adults: A Single-Center Experience in Spanish Population.

20.500.12530/87908Introduction: Morgagni hernia (MH) is a rare congenital disorder, especially in adults, accounting for 2%-4% of all congenital diaphragmatic hernias. Materials and Methods: Retrospective review of all patients who underwent surgical repair of MH at our center from 1991 to 2022. A descriptive analysis was performed. Results: Eighteen patients presented with MH, of whom 11 (61.11%) were female, with a median age of 67.60 (IQR 50.25-84.50) years old. Six (33.33%) were asymptomatic and 12 (66.67%) presented with symptoms, being dyspnea (4; 33.33%) the most common. On the group of symptomatic patients, the computed tomography scan (8; 66.67%) was the most frequent diagnostic test. Whereas in the asymptomatic group, 5 patients (83.33%) were diagnosed intraoperatively, during surgery for other reasons. MH was mostly located on the right (16; 88.89%). Hernia contents included omentum and colon (10; 55.56%), omentum (5; 27.78%), and stomach (3; 16.67%). All patients underwent surgical repair, needing in 3 cases (16.67%) emergency surgery. Surgical approaches included 10 laparoscopies (55.56%), 7 laparotomies (38.89%), and 1 thoracotomy (5.55%). Repair was generally performed whether by primary closure in 8 patients (44.4%) or by mesh implantation in 10 (55.56%). The median hospital stay was 6 days (IQR 3-10). Three patients presented complications (17.65%): urinary tract infection (1 patient), intra-abdominal collection (1 patient), and the last 1 presented with renal failure and pneumonia. The median follow-up was 74 months (IQR 4.5-130). No recurrence was described. Conclusions: MH is a rare condition in the adult population. In our series most patients presented with symptoms. The gold standard treatment is surgical repair, being the laparoscopic approach the most frequent. The complications rate was relatively low and no recurrence was described in our study

Baja incidencia y alta mortalidad por COVID-19 en Cirugía General durante la primera ola de la pandemia

Introducción y objetivo:La infección por coronavirus (COVID-19) en pacientes intervenidos es causa de importante mortalidad postoperatoria, aunque su incidencia es variable. El objetivo primario fue evaluar la incidencia de COVID-19 en los pacientes intervenidos en nuestro Servicio de Cirugía General y Digestiva, durante el máximo impacto de la pandemia en España. El objetivo secundario fue evaluar la mortalidad perioperatoria y determinar los factores de riesgo para la infección por COVID-19.Material y métodos:Estudio observacional retrospectivo de pacientes consecutivos sometidos a Cirugía General y Digestiva con ingreso superior a 24 horas, del 1 de febrero de 2020 al 30 de abril de 2020 en un hospital terciario de Madrid, España.Resultados:Se analizaron 441 pacientes: 423 sin COVID-19 y 18 con COVID-19. Las características preoperatorias y operatorias fueron similares para ambos grupos, salvo por el grado ASA (American Society of Anesthesiologists).La incidencia de COVID-19 en los pacientes intervenidos fue del 4,1 %. La mortalidad postoperatoria fue elevada, del 22,2 % en pacientes con COVID‑19, frente a un 2,8 % en pacientes no COVID‑19 (p: 0,003). Los factores de riesgo para la infección por COVID-19 en los pacientes intervenidos fueron una estancia hospitalaria prolongada (OR: 1,035 [95 % CI: 1,007 ‑ 1,065]) y la reintervención quirúrgica (OR: 5,025 [95 % CI: 1,650 – 15,311]).Conclusión:Las intervenciones durante la pandemia de COVID-19 causaron una baja tasa de infección con elevada mortalidad postoperatoria. La intervención quirúrgica debe valorarse frente al riesgo adicional para el paciente en contextos de alta transmisión.</jats:p
