Zusammenfassung: | This study was conducted to induce and evaluate irreversible hepatic fibrosis in dogs by surgical closure of the major duodenal orifice. the study was performed on six healthy local adult dogs. irreversible hepatic fibrosis was surgically induced in all animals by surgical closure of major duodenal papilla using non-absorbable suture material for 60 days. induced hepatic fibrosis was evaluated by clinical, Ultrasonographical examination, laboratory and histopathological methods. the clinical manifestation of the jaundiced dogs showed reduced food intake, pale-yellowish mucus membrane, inflammatory signs of wound site and severe post-operative pain. biochemically, there was significant increased values of the aspartate aminotransferase, alkaline phosphatase, alanine aminotransferase, indirect bilirubin, direct bilirubin and total bilirubin especially during first two days after surgery followed by a gradual decrease of these values until the end of the but still higher than normal values. Ultrasonographic examinations showed abnormal change in the liver tissue such as increase in both size and wall thickness of the gall bladder and mottled heterogeneous appearance of the liver during the first two weeks following the surgical induction of the hepatic fibrosis and lasted until the end of the study. histopathological evaluation of liver samples revealed necrosis of hepatocytes and deposition of eosinophilic material, infiltration of inflammatory cells, recent thrombus in the hepatic vein, fatty change. in conclusion, surgical induction of irreversible hepatic fibrosis in dogs was feasible technique by surgical closure of major duodenal papilla and the results were confirmed by the clinical, Ultrasonographical, laboratory and histopathological examination.
تم إجراء هذه الدراسة لغرض إحداث تليف الكبد الغير الانعكاسي جراحيا في الكلاب. أجريت التجربة على ستة من الكلاب المحلية البالغة من كلا الجنسين والسليمة من الأمراض. تم استحداث تليف الكبد الغير الانعكاسي عن طريق غلق فتحة قناة الصفراء الرئيسية داخل الاثني عشر باستخدام خيط جراحي غير ممتص نوع سلك بعد إجراء فتحة بطول 10 سم. تمت متابعة حيوانات التجربة سريريا مع قياس مستوى أنزيمات الكبد بالدم والفحص بالأمواج فوق الصوتية أسبوعيا ولمدة ستون يوما. في نهاية التجربة تم أخذ عينات من مناطق مختلفة من الكبد لغرض إجراء الفحص النسجي. أظهرت نتائج الدراسة حدوث تليف الكبد الانعكاسي تدريجيا تمثلت بحصول اصفرار في الغشاء المخاطي للعين والفم مع فقدان الشهية مع ملاحظة حدوث ألم شديد. لوحظ حدوث تأقلم مع تحسن تدريجي في الحالة الصحية للحيوان |
