The aim of the study is retrospectively evaluating all features of endoscopic and pathological diagnoses of cases who underwent upper and lower gastrointestinal endoscopy.
Gastrointestinal system endoscopy has an important place in the diagnosis and treatment of many diseases related to this system and provides an alternative to current surgical methods with its ever-expanding field of application. Upper and lower gastrointestinal endoscopy procedures are performed with many indications, such as new complaints in the gastrointestinal tract at the age of 50 and over, family history of gastrointestinal malignancy. In addition, the importance of endoscopy is gradually increasing as tissue and cell samples can be taken for histopathological studies and endoscopic treatment of some diseases. The aim of the study is to review patients' indications, distribution by age and gender, frequency of lesions diagnosed on endoscopy, prevalence, size, histology and location of polyps detected and excised, results of endoscopic and pathological diagnoses. The study population consists of the patients who were examined at the Istanbul Sultanbeyli State Hospital Endoscopy Unit between 01.01.2016 and 01.01.2021. The patients' data will be scanned retrospectively by accessing their files from the computer database.
