Resultados del manejo no operatorio en trauma hepático de los pacientes que se presentaron al servicio de urgencias del Hospital San Vicente Fundación, Medellín

Introducción. El hígado continúa siendo uno de los órganos más afectados en los pacientes con trauma. Su evaluación y manejo han cambiado sustancialmente con los avances tecnológicos en cuanto a diagnóstico y las técnicas de manejo menos invasivas. El objetivo de este estudio fue realizar un análisis de los resultados del manejo no operatorio del trauma hepático en cuanto a incidencia, eficacia, morbimortalidad, necesidad de intervención quirúrgica, tasa y factores relacionados con el fallo del manejo no operatorio. Métodos. Se realizó un estudio descriptivo observacional retrospectivo, analizando pacientes con trauma hepático confirmado con tomografía o cirugía, durante un periodo de 72 meses, en el Hospital Universitario San Vicente Fundación, un centro de IV nivel de atención, en Medellín, Colombia. Resultados. Se incluyeron 341 pacientes con trauma hepático, 224 por trauma penetrante y 117 por trauma cerrado. En trauma penetrante, 208 pacientes fueron llevados a cirugía inmediatamente, el resto fueron manejados de manera no operatoria, con una falla en el manejo en 20 pacientes. En trauma cerrado, 22 fueron llevados a cirugía inmediata y 95 sometidos a manejo no operatorio, con una falla en 9 pacientes. La mortalidad global fue de 9,7 % y la mortalidad relacionada al trauma hepático fue de 4,4 %. El grado del trauma, el índice de severidad del trauma y las lesiones abdominales no hepáticas no se consideraron factores de riesgo para la falla del manejo no operatorio. Conclusiones. El manejo no operatorio continúa siendo una alternativa segura y efectiva para pacientes con trauma hepático, sobretodo en trauma cerrado. En trauma penetrante se debe realizar una adecuada selección de los pacientes.

Some Special Aspects of Liver Repair after Resection and Administration of Multipotent Stromal Cells in Experiment

Changes in rat liver after resection and injection of autologous multipotent mesenchymal stromal cells of bone marrow origin (MSCs) transfected with the GFP gene and cell membranes stained with red-fluorescent lipophilic membrane dye were studied by light microscopy. It was found that after the introduction of MSCs into the damaged liver, their differentiation into any cells was not found. However, under the conditions of MSCs use, the number of neutrophils in the parenchyma normalizes earlier, and necrosis and hemorrhages disappear more quickly. It was concluded that the use of MSCs at liver resection for the rapid restoration of an organ is inappropriate, since the injected cells in vivo do not differentiate either into hepatocytes, into epithelial cells of bile capillaries, into endotheliocytes and pericytes of the vascular membranes, into fibroblasts of the scar or other connective tissue structures, or into any other cells present in the liver.

Accident-related hepatic trauma in a medical clinical center in eastern China: a cross-sectional study

Background

The treatment of hepatic injury can be complex. Medical clinical centers are often the first line hospitals for the diagnosis and treatment of hepatic trauma in China. The aim of the study is to summarize the experience in the diagnosis and treatment of hepatic trauma in one medical clinical center in China.

Methods

This retrospective study included patients with hepatic trauma admitted between January 2002 and December 2019 at the Xishan People’s Hospital of Wuxi. The outcomes were cure rate and death within 14 days post-discharge.

Results

Among the 318 patients with hepatic trauma, 146 patients underwent surgical treatment, and 172 received conservative treatment; three patients were transferred to other hospitals for further treatment; 283 patients were cured, and 35 died. Severe hepatic trauma occurred in 74 patients, with a mortality rate of 31.1% and accounting for 65.7% of total mortality. American Association for the Surgery of Trauma (AAST) grading ≥ III (OR = 3.51, 95%CI: 1.32–9.37, P = 0.012) and multiple organ injury (OR = 7.51, 95%CI: 2.51–22.46, P < 0.001) were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death (OR = 0.08, 95%CI: 0.01–0.45, P = 0.004). Among patients with ASST ≥ III and who underwent surgery, age (OR = 5.29, 95%CI: 1.37–20.33, P = 0.015) and peri-hepatic packing (PHP) (OR = 5.54, 95%CI: 1.43–21.487, P = 0.013) were independently associated with death.

Conclusions

AAST grading ≥ III and multiple organ injury were independently associated with death. Among patients with AAST grading ≥ III, surgery was an independent protective factor for death. Among patients with ASST ≥ III and who underwent surgery, age and PHP were independently associated with death.
