Benign pancreatic hyperenzymemia, Gullo’s syndrome. Focus on this clinical challenge: a monocentric retrospective study

BACKGROUND: An abnormal and chronic rise of pancreatic enzymes in the blood is most often due to pancreatic diseases, primarily inflammatory or neoplastic, or to numerous extra-pancreatic pathologies. Benign chronic pancreatic hyperenzymemia was described for the first time - as a separate nosological entity - in 1996 by Lucio Gullo et al. They demonstrated the existence of a benign chronic pancreatic hyperenzymemia in asymptomatic subjects and without clinical implications; however, a follow-up of at least 1-2 years is necessary during which no specific symptomatology or morpho-functional impairment of the pancreas should occur, also evaluated through the aid of instrumental diagnostic investigations such as ultrasonography (US), Computerized Tomography (CT) or Magnetic Resonance Cholangio Pancreatography (MRCP). METHODS: This study was performed with the analysis of a group of 43 subjects arrived at the observation of the Gastroenterology Team of Policlinico Hospital “G. Rodolico” in Catania-Italy which presented a chronic pancreatic hyperenzymemia, in order to establish the actual benignity of this condition over time. RESULTS: During the follow-up, pancreatic alterations and hyperenzymemia were found in 10 patients, while hyperenzymemia was not associated with pancreatic modification in 33 patients. CONCLUSIONS: Because of this enzymatic elevation - often conspicuous and lasting - the patient is often particularly anxious. For the same reason, the patient frequently undergoes very expensive laboratory and instrumental diagnostic methods. Good knowledge of the syndrome makes it possible to manage the event more rationally, also to reduce management costs to a minimum.
