Purpose - Chronic pancreatitis is an inflammatory disease responsible for pain partially explained by pancreatic duct dilatation. Early surgery has become the treatment of choice for hypertrophic pancreatic head with main pancreatic duct dilatation. Frey procedure (FP), combining both surgical resection and decompression, is one of the standard surgical procedures. However, a "step-up approach" with endoscopic or limited surgical procedures is still frequently proposed before referring to expert pancreatic centres. The aim of the study was to evaluate the impact of a prior treatment on post-operative complications of FP. Methods - All 61 consecutive patients who underwent FP between 2006 and 2017 were included. Perioperative data and outcomes were analyzed and compared according to the presence of a prior treatment. Results - Twenty-four patients did not receive any prior treatment and thirty-seven patients had a prior endoscopic or limited surgical treatment. Preoperative data and outcomes were similar between the 2 groups. The rate of biliary derivation during FP was significantly higher in the group without prior endoscopic procedure. A prior treatment was not a risk factor for major morbidity (Clavien grade ≥ III). Conclusions - A first attempt of endoscopic or limited surgical procedures before FP may not influence post-operative complications. Even if not recommended, a "step-up approach" proposing a first less invasive treatment could still be proposed to the patients who want to delay a morbid surgical procedure.
