Pancreas; Fistula

The purpose of this study is to evaluate the impact of compliance with enhanced recovery after surgery (ERAS) program on patient reported outcomes (PROs), surgery-specific outcomes and stress response after pancreatic surgery. This prospective observational study will include all consecutive patients undergoing pancreatic surgery over a period of three years (2022 - 2025) at two sites, namely University General Hospital of Larissa and IASO Thessalias, in Greece. Patients will be prospectively enrolled after written informed consent. Data will be collected on patient characteristics, surgical and anaesthetic techniques, complications, and length of stay. Quality of life questionnaires will be administered to patients preoperatively, on the fith postoperative day, first follow-up after discharge, one month and six months after the operation. The stress response will be assessed by measuring the Neutrophil-Lymphocyte Ratio and Platelet-Lymphocyte Ratio (NLR and PLR) preoperatively, and on the first five postoperative days. Data will be collected on pancreatic surgery-specific complications such as delayed gastric emptying (DGE), post-pancreatectomy haemorrhage (PPH) and postoperative pancreatic fistula (POPF) formation. Anonymised data will be uploaded by the principal investigator on a protected excel spreadsheet for analysis.

This prospective, observational study evaluates the rate of postoperative pancreatic fistula (POPF) following distal pancreatectomy (DP) using the AEON™ Endostapler. The study involves 110 patients undergoing DP and assesses primary outcomes based on the International Study Group of Pancreatic Fistula (ISGPF) classification, alongside secondary perioperative parameters. The findings aim to optimize surgical techniques, reduce complications, and improve healthcare outcomes.

Main objective: The main end-point of this study is to compare in a randomized clinical trial that radiofrequency-assisted pancreas transection (RF) reduces the incidence of postoperative pancreatic fistula (POPF) compared to the classical method of transection (stapler). As secondary end-points, other clinical and demographic variables of the patients will be evaluated (sex, age, ASA classification, consistency of the pancreas, as well as the type of procedure, open or laparoscopic surgery, estimated intraoperative bleeding, pancreatic duct size, duration of intervention, type of tumor and quality of lymphatic resection). Methodology: Phase III prospective multicenter study in patients undergoing distal pancreatectomy for any origin. All consecutive patients who undergo a distal pancreatectomy for any cause in a multicenter setting will be included. A simple randomization of the participants to the RFA group or to the control group (stapler) will be carried out. The incidence of pancreatic fistula will be assessed as main variable; predictive multivariable models with multiple regression for quantitative variables, logistic regression for categorical variables and Cox regression for survival analyzes. In addition to histological study, molecular analysis of resection specimen and clinical and radiological follow-up with volumetry of necrosis in the area of post-pancreatectomy transection will be performed.
