The effect of stomach’s different fullness levels on the topography of intestines in New Zealand rabbit (Oryctolagus cuniculus L.)

Yeni Zelanda tavşanında (Oryctolagus cuniculus L.) midenin farklı doluluk derecelerinin bağırsakların topografisi üzerine etkisi. Amaç: Yeni Zelanda tavşanlarında midenin farklı doluluk derecelerinin karın organlarının topografisi üzerine etkisi araştırıldı. Gereç ve Yöntem: Tavşanlar; normal beslenenler, midesi boş ve midesi dolu olmak üzere 8'er adetlik 3 gruba ayrıldı. Doygunlukları farklı olan her üç gruptaki tavşanlardan 6 tanesi (3x2) diseke edildi. Bu üç grup hayvandan paramedian ve transversal kesitler alındı. Bulgular: Çalışmada Yeni Zelanda tavşanında mide boşken duodenum'un başlangıcının arcus costales'in bitiş seviyesinde olduğu görüldü. Çalışmada cecum'un midesi boş tavşanlarda karın boşluğunun ventral'inde, midenin curvatura ventriculi major'u ile pelvis boşluğu girişi arasında, karın boşluğunun sağ tarafında, sağ karın duvarına temas eder durumda bulunduğu görüldü. Midesi dolu tavşanlarda ise cecum'un curvatura ventriculi major'un sağ kısmının altında, sağ karın duvarına dayalı olarak caudal yönde uzandığı belirlendi. Midesi boş tavşanlarda colon'un regio umbilicalis'te cecum'un kıvrımları arasında ampulla coli halinde başladığı, midesi dolu tavşanlarda ise colon'un karın boşluğunun sağ ve ventral kısmında, median düzlemin sol kısmına da geçmiş pozisyonda, karın boşluğunun ventral duvarına temas eder durumda yerleştiği görülmüştür Öneri: Tavşanların normal abdomen bölgesinin kesit anatomisinde mide doluluğunun barsaklar üzerine etkili olabileceği ifade edilebilir.

Aim: The objective of the present study was examining the effect of stomach’s different fullness levels on the topography of abdominal organs in rabbits.Materials and Methods: Rabbits were divided into 3 groups, each of which consisting of 8 rabbits. 6 rabbits of those in each group with the same fullness level (3x2) were dissected. Paramedian and transversal sections were taken from this 3 groups.Results: It was observed that when the stomach was empty, duodenum’s beginning was on the ending level of arcus costales in New Zealand rabbits. When the stomach was full, it was pushed from pyloris towards the cranial. Cecum was observed to be in contact with right abdominal wall on the right side of the abdominal cavity as contacting uterus between stomach’s curvatura ventriculi major and pelvis cavity entry in ventral abdominal cavity in rabbits with empty stomachs. In rabbits with full stomachs, cecum was determined to extend caudally contacting right abdominal wall and it was located under the right side of curvatura ventriculi major. Colon was found to start as ampulla coli between the folds of cecum in region umbilicalis in rabbits with empty stomachs; whereas, it was located as being contacted with the ventral wall of abdominal cavity in a position passing the left part of median level in right and ventral part of the abdominal cavity in rabbits with full stomachs.Conclusion: It may be convcluded that fullness of the stomach effects on intestines in the cross-sectional anatomy of the normal abdominal region in the rabbit
