Resumen Antecedentes: El diagnóstico temprano del segmento intestinal necrótico resultante de una hernia inguinal incarcerada es crucial para reducir la morbilidad y la mortalidad. Objetivo: Investigar la eficacia del índice de De Ritis (IDR), también conocido como cociente de aspartato aminotransferasa a alanina aminotransferasa, como biomarcador de necrosis intestinal. Método: Estudio retrospectivo que incluyó a 132 pacientes que fueron intervenidos de urgencia por hernia inguinal incarcerada. Los pacientes se dividieron en dos grupos: los que se sometieron a resección intestinal por necrosis (grupo 1) y los que no (grupo 2). Se registraron los datos demográficos y clínicos de los pacientes. Usando los resultados de las pruebas de laboratorio, se calcularon el IDR, el índice neutrófilos-linfocitos (INL), el índice plaquetas-linfocitos (IPL), el índice linfocitos-monocitos (ILM) y el índice linfocitos-proteína C reactiva (ILPCR). Resultados: Las tasas de morbilidad, mortalidad y duración de la estancia para el grupo 1 fueron estadísticamente significativas (p < 0.0001). Los valores de IDR, INL, IPL, ILM, ILPCR del mismo grupo también fueron significativamente diferentes (p < 0.05). Conclusiones: El IDR puede utilizarse como biomarcador para el diagnóstico precoz de necrosis intestinal en pacientes con hernia inguinal incarcerada.

Abstract Purpose: Early diagnosis of necrotic bowel segment resulting from incarcerated inguinal hernia (IIH) is crucial for reducing morbidity and mortality. The aim of this study was to investigate the efficacy of the De Ritis ratio (DRR), also known as the ratio of aspartate aminotransferase to alanine aminotransferase, as a biomarker for intestinal necrosis. Methods: This retrospective study included 132 patients who underwent emergency surgery for IIH. Patients were divided into two groups: those who underwent bowel resection for necrosis (Group 1) and those who did not (Group 2). Patients' demographic and clinical data were recorded. Using laboratory test results, DRR, neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), lymphocyte-to-monocyte ratio (LMR), and lymphocyte-to-CRP ratio (LCR) were calculated. Results: The morbidity and mortality rates and the length of stay for Group 1 were statistically significantly different (p < 0.0001). The DRR, NLR, PLR, LMR, and LCR values of the same group were also significantly different (p < 0.05). Conclusion: DRR can be used as a biomarker for early diagnosis of bowel necrosis in patients with IIH.

ABSTRACT Purpose: To investigate experimentally the effects of Tropifexor, a farnesoid X receptor agonist, on liver injury in rats with obstructive jaundice. Methods: Forty healthy Wistar albino female rats were divided randomly in selected groups. These groups were the sham group, control group, vehicle solution group, Ursodeoxycholic acid group and Tropifexor group. Experimental obstructive jaundice was created in all groups, except the sham one. In the blood samples obtained, aspartate transaminase (AST), alanine transaminase (ALT), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT), total bilirubin and direct bilirubin levels were established and recorded. Additionally, liver malondialdehyde, myeloperoxidase and catalase enzyme activity in the tissue samples were studied. Histopathological analysis was also performed. Results: No statistical difference was found between the control group and the Tropifexor group when AST, ALT and ALP values were compared. However, it was found that the Tropifexor group had statistically significant decreases in the values of GGT, total bilirubin and direct bilirubin (p < 0.05). Additionally, Tropifexor decreased the median values of malondialdehyde and myeloperoxidase, but this difference was not statistically significant compared to the control group. Finally, the Tropifexor group was statistically significant in recurring histopathological liver damage indicators (p < 0.05). Conclusions: Tropifexor reduced liver damage due to obstructive jaundice.
