Giris ve Amaç:Gastrointestinal sistem hastaliklari demir esikliginin önemli nedenlerinden biridir. Biz bu çaliflma ile demir eksikligi olan hastalardaki üst ve alt gastrointestinal endoskopi bulgularini tanimlamayi amaçladik.Gereç ve Yöntem: ICD-10 kodlama sistemine göre demir eksikligi tanisi almifl hastalarin bulgulari retrospektif olarak tarandi. Üst ve alt gastrointestinal endoskopi bulgulari ile varsa biyopsi sonuçlari toplanarak tanimlayici istatistik ile degerlendirildi. Bulgular:Çaliflma için, ICD-10?a göre demir eksikligi tanisi almifl 1200 hastanin verileri gözden geçirildi. Degerlendirmeye alinan 207 hastanin 205?ine üst gastrointestinal endoskopi yapilmifl ve 116 hastadan mide, 84 hastadan duodenal biyopsi alinmiflti. Kolonoskopi yapilan 169 hastanin %30?unda herhangi bir patoloji saptanmazken, %4.7?sinde kolorektal kanser saptandi.Sonuç: Demir eksikligi gastrointestinal sistem patolojilerinin önemli bir bulgusudur. Üst ve alt gastrointestinal endoskopi bu bulguyu ortaya çikaran nedenleri arafltirmada önemli ve gerekli tani yöntemleridir.
Background and Aims: Diseases of the gastrointestinal tract are among the important causes of iron deficiency. Our aim was to identify upper and lower gastrointestinal endoscopic findings in patients with iron deficiency. Materials and Methods: Patients diagnosed with iron deficiency according to the ICD-10 coding system and who underwent upper and/or lower gastrointestinal system endoscopy were included in the study. Endoscopic and pathologic findings were collected for descriptive statistics. Results:Data of 1200 patients were reviewed. Two hundred and seven patients were included in the study. Upper and lower gastrointestinal endoscopy were performed in 205 and 169 patients, respectively. In upper gastrointestinal endoscopy, biopsies were taken from the stomach and second part of the duodenum in 116 and 84 patients, respectively. In lower gastrointestinal endoscopy, 30% of patients had no pathologic finding, whereas 4.7% of patients were diagnosed with colorectal cancer. Conclusions: Iron deficiency is an important finding in gastrointestinal diseases. Upper and lower endoscopic examination is vital for explaining the cause of iron deficiency.
