RESUMEN

INTRODUCTION: Metabolic (dysfunction) associated fatty liver disease (MAFLD) and cholelithiasis are highly prevalent and are associated with common risk factors such as obesity, hypertriglyceridemia, and fasting glucose levels; however, it is not clear whether cholelithiasis is associated with MAFLD or fibrosis. OBJECTIVE: To determine MAFLD severity and associated risk factors in patients diagnosed with cholelithiasis. MATERIALS AND METHODS: Observational, cross-sectional and prolective study (from October 2018 to March 2020) of patients undergoing elective laparoscopic cholecystectomy with liver biopsy, excluding other causes of hepatic disease or significant alcohol consumption. MAFLD detection was based on histology using the Kleiner score and one of the following criteria: overweight/obesity, T2DM, or evidence of metabolic dysregulation. The AST to Platelet Ratio Index, the NAFLD Fibrosis Score, the fibrosis-4 index and the hepatic steatosis index were performed to assess the relationship of non-invasive hepatic scores with histopathology. RESULTS: 80 patients median age (interquartile range) was 42 (18) years, with a BMI of 27.9 (6.11) Kg/m2. Of all patients, 58.8% had MAFLD, 78.7% were women, and 13.8% had the severe form (formerly named NASH). No substantial correlation between biochemical parameters and histopathological analysis of MAFLD and fibrosis was observed. CONCLUSION: Because cholelithiasis and MAFLD are highly prevalent diseases, it is essential to conduct studies on the relationship between both pathologies. Currently, liver biopsy is the best diagnostic method since the predictive biochemical models did not show a substantial correlation to classify MAFLD. Its early detection is relevant since a considerable percentage of advanced fibrosis (8.7%) was found.

RESUMEN

Objetivo: Realizar una revisión de la literatura actualizada, abordando los aspectos clínicos y epidemiológicos más relevantes asociados con la sobrevida del carcinoma hepatocelular y su relación con las estrategias terapéuticas que han demostrado un mejor resultado. Método: Se realizó una búsqueda bibliográfica empleando las bases de datos electrónicas Medline, Embase, Springerlink y PubMed para identificar documentos publicados desde el 1 de enero de 1985 hasta agosto de 2020. Resultados: Se analizaron el abordaje y el manejo quirúrgico del carcinoma hepatocelular en todo el mundo, comparando las dos principales estrategias terapéuticas que reportan mayor porcentaje de sobrevida global. Conclusiones: En el protocolo de estudio del carcinoma hepatocelular es necesario un enfoque multidisciplinario. Los pacientes con carcinoma hepatocelular avanzado se beneficiarían de una estrategia multimodal individualizada que consista en resección y en otros casos con el trasplante hepático.

RESUMEN

Colorectal cancer is one of the main neoplasms worldwide; at the time of diagnosis about 25% of cases already have an advanced stage with the presence of metastases. A 58-year-old female presented with nausea, vomiting, and black stools and diffuse abdominal pain associated with 7% weight loss. She was referred to our hospital with signs of digestive tract bleeding and anemic syndrome. Panendoscopy revealed body and fundus gastropathy and presence of Helicobacter pylori, and colonoscopy showed a neoplastic lesion at the ascending colon level. A synchronous resection was performed in a single surgical time of colorectal cancer and liver metastases with a duration of 4 h and bleeding of 900 mL. The oral feeding started 24 h after surgery, presenting gas channeling at 24 h and evacuations at 48 h. The total intrahospital stay was 5 days. Synchronous resection of hepatic metastases in colorectal cancer is still rarely performed, despite the fact that in recent years the number of cases has increased because of better surgical techniques. Synchronous resection of colorectal cancer and liver metastases can be performed safely, without increasing transoperative mortality when performed in specialized centers with a multidisciplinary team; however, it is essential to emphasize the importance of negative surgical margins (R0) of the primary tumor and later to be complemented with adjuvant treatment with chemotherapy.
