Abstract

Objective: Gastrointestinal motility and functional motility disorders causing either delayed or accelerated gastric emptying (GE) may result in similar symptoms including nausea, vomiting, early satiety, fullness, bloating, and abdominal discomfort or pain. Hence, it is important to evaluate patients for both rapid and delayed GE in the same test. The gold standard technique to measure GE is scin- tigraphy by radiolabeled test meals. The aim of this study was to test alternative Tc-99m agents to label eggs as the solid meal and compare to Tc-99m sulfur colloid (SC) for gastric emptying studies. Methods: In search of alternative agents for gastric emptying studies, we mixed and fried eggs with four different particulate com- pounds (Tc-99m labeled SC, tin colloid, nanocolloid and MAA), as well as with free pertechnetate and Tc-99m DTPA. We then mea- sured the stability of these compounds in simulated gastric juice. Results: Our experiments demonstrated that in addition to Tc-99m sulfur colloid;Tc-99m MAA, Tc-99m nanocolloid and Tc-99m tin colloid also appear to make stable complexes with eggs in acidic environment. Conclusion: Therefore, these agents may be used for gastric emptying studies which could be more practical in routine conditions.

Özet

Amaç: Gastrointestinal motilite ve fonksiyonel motilite bozuklukları erken ya da geç mide boşalmasından kaynaklanan bulantı, kusma, erken doyma ve şişkinlik gibi abdominal rahatsızlık ya da ağrıya neden olan benzer semptomlar gösterir. Bu yüzden hastanın erken veya geç mide boşalma zamanını aynı test ile ölçmek önemlidir. Gastrik boşalmayı ölçmek için, altın standart yöntem, radyoişaretli besinler kullanılarak yapılan sintigrafi tekniğidir. Bu çalışmanın amacı alternatif Tc-99m radyofaramasötiklerini katı besin olarak yumurta ile birleştirip, mide boşalma sintigrafisi için kullanılabilirliğini Tc-99m sulfur kolloid (SC) ile karşılaştırarak test etmektir. Yöntem: Çalışmada mide boşalma sintigrafisi için alternatif radyofarmasötikler olarak dört farklı partiküllü radyofarmasötik (Tc-99m ile işaretli SC, kalay kolloid, nano kolloid ve MAA) ile teknesyum perteknetat ve Tc-99m DTPA bileşikleri yumurta ile karıştırıldı ve pişirildi. Bu bileşiklerin stabiliteleri mide suyu benzeri ortamda değerlendirildi. Bulgular: Sonuçlar Tc-99m SC’e ilaveten Tc-99m MAA, Tc-99m nano kolloid ve Tc-99m kalay kolloidin de asidik ortamda yumurta ile stabil kompleksler oluşturduğunu göstermiştir. Mide boşalma sintigrafisi için bu ajanların da kullanılabilmesi günlük çalışma koşullarında kolaylık sağlayacaktır
