Background: Echoendoscopy combines endoscopic and ultrasound image to visualize the wall of the gastrointestinal tract and its adjacent structures. Since its introduction more than a decade ago, endoscopic ultrasonographyguided fine-needle puncture has been a reliable tool for obtaining material in patients with gastrointestinal tract, pancreatic and chest malignancies. Objective: To correlate the ecoendoscopic diagnosis with histological diagnosis and evaluate the follow-up of all patients. Results: 106 patients, 59 (55.7%) female, 47 (44.3%) male aged 18 to 84 years (mean 55 μ 15 years). Radial EE helped diagnose solid pancreatic lesions 35.8% (n = 38), wall lesions 17.9% (n = 19), pancreatic cystic lesions 14.2% (n = 15), chronic and / or immunologic pancreatitis 9.4% (n = 10), lymph nodes 8.5% (n = 9) among others. With FNA- EE the results were solid pancreatic lesions 39.6% (n = 8), Wall lesions 18.9 (n = 20 ), pancreatic cystic lesions 14.2% (n = 15), chronic and / or immunologic pancreatitis 8.5% (n = 9), lymph nodes 7.5% (n = 8). Comparing linear EE with radial EE it was found that puncture diagnosis coincided 96%. The histological diagnosis was reported as positive for malignancy in 53.8% (n = 57), negative for malignancy 32.1% (n = 34), suspicious for malignancy 5.7% (n = 6), and cellular atypia / or undetermined 4.7% (n = 5), inappropriate sample 3.8% (n = 4). In 74.8% agreed the the EE linear finding coincided with the histological diagnosis. A total of 58% (n = 62) was treated, and 41.5% (n = 44) received no treatment; of 70 patients who were not currently operated 23% (n = 16) died and 77% ( n = 54) lives and in those who received some treatment 11% (n = 4) died and 89% (n = 32) lives. Conclusions: The diagnosis by radial EE can be corroborated positively with FNA -EE, and this in turn be correlated with the results of the histology becoming an essential part in the accuracy of the conclusion of the histological diagnosis of the sample obtained by puncture.
