Son un sistema de clasificación que indica la gravedad de la enfermedad en función de los signos, síntomas, estudios de laboratorio, imagen y laparoscopia diagnóstica. Aunque ambos sistemas han demostrado ser útiles en la toma de decisiones clínicas, no se ha estudiado su relación entre sí en pacientes con y sin colecistitis aguda.  Objetivo:  Evaluar la relación entre la clasificación de colecistitis de TG18 y PGS en pacientes con y sin colecistitis aguda.  Material y métodos:  Se realizó un estudio transversal, retrospectivo, que incluyó a 100 pacientes postoperados de colecistectomía laparoscópica. Se documentó el diagnóstico de colecistitis aguda y no aguda con las guías TG18 en la nota de ingreso y la PGS en la nota postoperatoria del expediente clínico.  Resultados:  Se identificó una relación positiva entre la colecistitis crónica no agudizada y colecistitis aguda con la PGS (p = 0.001) y una relación negativa entre colecistitis aguda y PGS (p = 0.106).  Conclusión:  La severidad de la PGS está relacionada con la condición aguda o no aguda de la colecistitis.]]></p></abstract>

They are a classification system that indicates the severity of the disease based on signs, symptoms, laboratory studies, imaging, and diagnostic laparoscopy. Although both systems have proven useful in clinical decision-making, their relationship with each other has not been studied in patients with and without acute cholecystitis.  Objective:  evaluate the relationship between TG18 cholecystitis classification and PGS in patients with and without acute cholecystitis.  Material and methods:  A retrospective, cross-sectional study was carried out that included 100 postoperative laparoscopic cholecystectomy patients. The diagnosis of acute and non-acute cholecystitis was documented with the TG18 guidelines in the admission note and the PGS in the postoperative note of the clinical record.  Results:  A positive relationship was identified between non-exacerbated chronic cholecystitis and acute cholecystitis with PGS (p = 0.001) and a negative relationship between acute cholecystitis and PGS (p = 0.106).  Conclusion:  The severity of PGS is related to the acute or non-acute condition of cholecystitis.]]></p></abstract>
