摘要

AIM:To propose a diagnostic algorithm for preoperatively predicting the need for surgical intervention.METHODS:The study included 56 patients(27 men and 29 women) with a final diagnosis of cystic pancreatic lesions.The following materials were used:ultrasonic equipment with 3.5 and 7 MHz linear,convex and biopsical transducers.Multidetector computed tomography(MDCT) investigations were performed using a 16-slice scanner.Images were obtained following the oral administration of 200 mL water and 100 mL intravenous iopamidol(300 mg/mL) administered by pump injector at a rate of 3 mL/s(40 and 60 s post-injection,respectively) using 0.5 mm detectors,reconstructed at 1 mm(pancreatic phase) or 2 mm(portal venous phase) increments.The table feed was 10 mm per rotation.Images were acquired in the pancreatic and portal venous phases of contrast enhancement.The 'Chiba' needles 18,20,22,23 G and an automatic aspiration system were used in conjunction with the followingmethods of guiding the interventional procedures:(1) 'free-hand' biopsy and puncture method under ultrasound(US) or computed tomography(CT) control;(2) guiding method using biopsical transducer.RESULTS:All 56 patients in this study underwent at least two cuts imaging survey methods,such as US,CT or magnetic resonance imaging(MRI).The most common preoperative diagnostic examination was US scan-56 patients(100%).MDCT studies were conducted in 49(87.50%) and MRI in 13(23.21%).More than half of patients surveyed(37) underwent some type of interventional procedure:25-fine-needle aspiration and 29-fine needle aspiration biopsy(FNAB),as part of the examination.Thirty-four patients of all 56 patients underwent surgery because of histological evidence of malignancy after the FNAB for cystic lesions of the pancreas.Distal pancreatectomy with splenectomy was the most common operative approach in 13 patients,followed by Whipple resection in 11 and distal pancreatectomy without splenectomy in 7.Three patients were treated with total pancreatectomy due to the presence of a
