RESUMEN
Conditions affecting the upper digestive system are often seen in clinical practice and are associated with a high rate of death and disability. Histopathological confirmation is one of the foundations for good treatment planning and the definite diagnosis of illnesses of the upper gastrointestinal tract. The numerous methods employed in the diagnosis of gastrointestinal lesions have come a long way in the previous 25 years. The identification and diagnosis of gastrointestinal lesions have been substantially aided by the development of endoscopy, endoscopic biopsy, and other surgical techniques. This research aimed to examine the variety of gastrointestinal tract (GI) lesions and to draw connections between the clinical and pathological manifestations of these conditions. Materials and Methods: A two-year cross-sectional study was conducted in the Department of Pathology, from June 2018 to May 2020, which included surgical specimens of 140 cases from the upper gastrointestinal tract, of which 111 cases were biopsy, and 29 cases were resected surgical specimens. The data were analyzed using SPSS software. Furthermore, P values, sensitivity, specificity, positive predictive value, and negative predictive value were calculated. Results: This study was a two-year cross-sectional study conducted in the Department of Pathology during the period of June 2018-May 2020.
