Objectives: Oncologic imaging, suspected intestinal leaks, fistulas, abscesses and collections, abdominal pain, and computed tomography colonography are the indications for the use of oral contrast media. The distal colon and rectum opacification is not always achieved with the standard technique in routine studies. Our aim is to compare the effect of 1.5-hour vs. 4-6-hour contrast media ingestion durations on distal colon and rectum opacification in abdominal computed tomography.
Methods: Adult patients in the year of 2023 were retrospectively grouped: those with a 4-6 hour contrast media ingestion duration (study group) and age- and sex-matched patients with a 1.5 hour contrast media ingestion duration (control group). After exclusions, there were 200 patients in total. Groups were evaluated for the association between contrast media ingestion durations and the most distal bowel segment opacified.
Results: Results showed a significant association between contrast material ingestion duration and the most distal opacified bowel segment (p<0.001). The contrast reached the rectum in 37% of the 1.5-hour group and 67% of the 4-6 hour group. Sex also affected opacification, with men having more distal bowel opacification (p=0.017).
Conclusions: Longer contrast media ingestion durations lead to almost 1.5-2 times more distal colon and rectum opacification, which could be adjusted based on suspected pathology location, though longer durations may reduce patient compliance.

Amaç: Oral kontrast madde endikasyonları olarak, onkolojik görüntüleme, şüpheli bağırsak kaçakları, fistüller, abse ve koleksiyonlar, karın ağrısı ve bilgisayarlı tomografi (BT) kolonoskopi sayılabilir. Standart kontrast içme sürelerinde rutin tetkiklerde distal kolon ve rektum opaklaşması her zaman sağlanamamaktadır. Amacımız, abdominal BT’de 1,5 saatlik ve 4–6 saatlik kontrast madde içme süresinin distal kolon ve rektum opaklaşması üzerine etkisini değerlendirmektir.
Yöntemler: 2023 yılında oral kontrastlı abdomen BT’si olan yetişkin hastalar retrospektif, 4–6 saatlik (çalışma grubu) ve yaş-cinsiyet olarak eşleştirilmiş 1,5 saatlik (kontrol grubu) kontrast madde içme süresine sahip olanlar olarak iki gruba ayrıldı. Dışlama kriterleri uygulandıktan sonra toplamda 200 hasta kalmıştır. Gruplar, kontrast madde içme süreleri ile opaklaşan en distal bağırsak segmenti arasındaki ilişki yönünden değerlendirilmiştir.
Bulgular: Kontrast madde içme süresi ile opaklaşan en distal bağırsak segmenti arasında anlamlı bir ilişki bulundu (p<0,001). 1,5 saatlik grubun %37’sinde kontrast rektuma ulaşırken, 4–6 saatlik grubun %67’sinde ulaştı. Ayrıca, erkek hastalarda kontrast maddenin aynı sürede, daha distal bağırsağa ulaştığı (p=0,017) gözlendi.
Sonuç: Daha uzun kontrast madde içme süreleri, patolojinin şüphelenildiği bağırsak segmentine göre seçilerek yaklaşık 1,5–2 kat daha çok hastada distal kolon ve rektum opaklaşması elde edilebilir. Fakat uzun kontrast madde içme sürelerinin hasta uyumunu azaltabileceği göz önünde bulundurulmalıdır.
