RESUMEN
Pancreatic surgery is one of the surgeries burdened with the highest mortality and morbidity rate. This is due both to the aggressive biological nature of the pathology affecting the organ and to the technical difficulties associated with surgery. A further aspect on which research is focusing is represented by inflammation related to oncological pathology. Inflammation plays an important role in tumor progression, and growing evidence has confirmed that the fibrinogen-to-albumin ratio (FAR) is an important prognostic factor for overall survival (OS) in malignant tumors. Inflammatory markers had demonstrated also a role in the prediction of postoperative complication after pancreatic surgery. We speculate that FAR, as an easily available, cost-effective, and non-invasive prognostic indicator for pancreatic cancer patients, could help to identify patients at increased risk of postoperative pancreatic fistula (POPF). We therefore retrospectively analyzed the data relating to 117 pancreatic resections relating direct and indirect markers of inflammation with the incidence of post-operative complications.
RESUMEN
PURPOSE: Following Lichtenstein's technique, over the last 15 years several variation have been proposed, such as Trabucco's sutureless technique and the use of two self-regulating prostheses, proposed by Valenti that have given excellent results. The aim of this prospective and randomised study was to determine whether there are differences in the results obtained with these three techniques. METHODS: Of 812 patients submitted to inguinal hernia repair, we selected and randomised 162 patients into three groups of 54 patients each: Lichtenstein (Group L), Trabucco (Group T) and Valenti (Group V). Surgical procedures were performed in all cases by residents in surgery using local anaesthesia. Primary endpoint was intensity of postoperative pain. Median follow-up was 8 years. RESULTS: The primary analysis of postoperative pain at 48 h did not report any significant difference between the three groups as for secondary analyses except that the Trabucco procedure took less operative time than the Lichtenstein, and the Valenti group was more painful than the Lichtenstein group at the third postoperative day. In our series median operation time was 60 min. Recurrence rate was 1.85%. CONCLUSIONS: Surgical repair of inguinal hernia according to the Lichtenstein, Trabucco and Valenti techniques is safe and easy to perform regardless of the surgical experience of the operator, with excellent results and no differences due to technique used as regards almost all of the parameters studied.
