Análise da presença de coledocolitíase, através da colangiopancreatografia por ressonância magnética nuclear e colangiografia peroperatório em indivíduos submetidos a colecistectomia.

Abstract

Introduction: Cholelithiasis is defined by the presence of gallbladder stones and is one of the most common disorders of the digestive system, with choledocholithiasis being the most common complication and requiring a better method for its diagnosis. Thus, the objective of this study was analyze the presence of choledocholithiasis through magnetic resonance cholangiopancreatography and perioperative cholangiography in individuals undergoing cholecystectomy. Methods: This is a longitudinal, cohort and retrospective study, in which 120 patients with a diagnosis of cholelithiasis and suspected choledocholithiasis were evaluated. Results: It was observed that in the imaging exams the diagnoses were cholelithiasis, choledocholithiasis, dilatation of the biliary tract, cholelithiasis plus choledocholithiasis, cholelithiasis plus dilatation of the biliary tract, cholecystitis and pancreatitis. In the presence of positive MRI cholangiopancreatography for choledocholithiasis, there was a risk of 105 times greater, respectively, of positive perioperative cholangiography for choledocholithiasis in the same patient. In the presence of choledocholithiasis on abdominal ultrasound, there was a nine times greater risk of positive perioperative cholangiography for choledocholithiasis. And in the positive perioperative cholangiography for choledocholithiasis there was a 104 times greater risk of positive resonance cholangiopancreatography for choledocholithiasis in the same patient and in the presence of choledocholithiasis on abdominal ultrasound there was a six times greater risk of positive resonance cholangiopancreatography for choledocholithiasis. Conclusion: Diagnostic magnetic resonance cholangiopancreatography has good concordance for the diagnosis of choledocholithiasis when compared with perioperative cholangiography. It can be said that this is a method with less invasion, less risk and less surgical time.
