ABSTRACT
Identifying biomarkers linked to pancreatic ductal adenocarcinoma (PDAC) and chronic pancreatitis (CP) is crucial for early detection, treatment, and prevention. Methods: Association analyses of 10 serological biomarkers involved in cell signalling (IFN-γ, IL-6, IL-8, IL-10), oxidative stress (superoxide dismutase (SOD) and glutathione peroxidase (GPx) enzyme activities, total glutathione (GSH), malondialdehyde (MDA) levels), and intestinal permeability proteins (zonulin, I-FABP2) were conducted across PDAC (n = 12), CP (n = 21) and control subjects (n = 23). A Mendelian randomisation (MR) approach was used to assess causality of the identified significant associations in two large genetic cohorts (FinnGen and UK Biobank). Results: Observational results showed a downregulation of SOD and GPx antioxidant enzyme activities in PDAC and CP patients, respectively, and higher MDA levels in CP patients. Logistic regression models revealed significant associations between CP and SOD activity (OR = 0.21, 95% CI [0.05, 0.89], per SD), GPx activity (OR = 0.28, 95% CI [0.10, 0.79], per SD), and MDA levels (OR = 2.05, 95% CI [1.36, 3.08], per SD). MR analyses, however, did not support causality. Conclusions: These findings would not support oxidative stress-related biomarkers as potential targets for pancreatic diseases prevention. Yet, further research is encouraged to assess their viability as non-invasive tools for early diagnosis, particularly in pre-diagnostic CP populations.
ABSTRACT
BACKGROUND: Laparoscopic procedures have gained popularity because they favor a faster recovery. In the same way, the establishment of an enhanced recovery after surgery (ERAS) program in major abdominal surgery has shortened the hospital stay. There are several studies that report the results on ERAS programs applied to open or laparoscopic hepatectomies or comparing one of them with the classic approach but few have compared the results between both within an ERAS program. OBJECTIVE: To compare the results between open and laparoscopic hepatectomies in the same ERAS program. METHOD: Thirty-six patients undergoing hepatectomies were enrolled in this study and were either laparoscopically or open in an identical ERAS program. Hospital stay and the number of complications were taken as primary end points. RESULTS: There were no significant differences between both groups in terms of hospital stay or number of complications. The differences were in a shorter time of surgery and an earlier ambulation in favor of open surgery and a better full recovery in favor of the laparoscopic approach. CONCLUSIONS: Initial data suggest that there would be no benefits in terms of hospital stay and complication rate of laparoscopic hepatectomies over open ones within an ERAS program.
ANTECEDENTES: Los procedimientos laparoscópicos ganaron popularidad porque favorecen una recuperación rápida. El establecimiento de programas ERAS (Enhanced Recovery After Surgery) en cirugía mayor abdominal ha acortado la estancia hospitalaria independientemente de la vía de abordaje. Varios trabajos informan los resultados sobre programas ERAS aplicados a hepatectomías abiertas o laparoscópicas, o comparando una de ellas con el abordaje clásico, pero pocos han comparado los resultados entre ambas dentro de un programa ERAS. OBJETIVO: Comparar, dentro un mismo programa ERAS, los resultados entre hepatectomías abiertas y laparoscópicas. MÉTODO: Se incorporaron a este estudio 36 pacientes sometidos a hepatectomías que fueron abordados por vía laparoscópica o abierta dentro de un programa ERAS. Los objetivos primarios fueron la estancia hospitalaria y el número de complicaciones. RESULTADOS: No hubo diferencias significativas entre ambos grupos en cuanto a estancia hospitalaria ni número de complicaciones. Las diferencias radicaron en un menor tiempo de cirugía y una deambulación más precoz a favor de la cirugía abierta, y una recuperación total mejor a favor del abordaje laparoscópico. CONCLUSIONES: Los datos iniciales sugieren que no habría beneficios en cuanto a estancia hospitalaria e índice de complicaciones de las hepatectomías laparoscópicas sobre las abiertas dentro de un programa ERAS.
