چکیده مقاله :
هدف از این مطالعه تعیین اندازه قطر مجرای سیستیک و مجرای مشترک صفراوی با روش اولتراسونوگرافی در سگ‌های ژرمن شیپرد بالغ با اطمینان ۹۵ درصد بود تا در تفسير نتايج و تصميم‌گيري‌هاي باليني استفاده شود. در این مطالعه توصیفی - مقطعی از 12 قلاده سگ ژرمن شیپرد بالغ (6 قلاده نر و 6 قلاده ماده) با میانگین وزنی 65/3 ±37/24 کیلوگرم و میانگین سنی 49/0 ±40/2 سال استفاده شد. در سگ‌های تحت مطالعه اولتراسونوگرافی در حالت خوابيده به پشت و خوابيده به پهلوي راست و چپ و در مرحله دم حیوان انجام گرفت. مطالعات آناتومی نیز متعاقب بی‌هوشی و در حین جراحی هر حیوان انجام گرفت. بر اساس نتایج این مطالعه در روش اولتراسونوگرافی، میانگین قطر مجرای سیستیک در سطح کیسه صفرا 58/0 ± 17/4 میلی‌متر بوده و میانگین قطر مجرای مشترک صفراوی در سطوح پورتا هپاتیس و پاپیلای بزرگ دوازده به ترتیب 48/0 ± 23/3 و 63/0 ± 14/3 میلی‌متر بود. قطر مجرای سیستیک در سطح کیسه صفرا در جنس نر بزرگ‌تر از جنس ماده و قطر مجرای مشترک صفراوی در سطح پورتا هپاتیس و پاپیلای بزرگ دوازده در جنس ماده بزرگ‌تر از جنس نر بود ولی این اختلاف‌ها معنی‌دار نبودند (P˃0.05). استانداردهای دقیق به دست آمده در این مطالعه می‌تواند در تفسير نتايج و ارزیابی‌های باليني برای تعيين اندازه طبيعي و غيرطبيعي قطر مجرای سیستیک و مجرای مشترک صفراوی در سگ‌های ژرمن شیپرد بالغ مورد استفاده قرار گیرد.
چکیده انگلیسی :
The current study aimed to evaluate the normal diameter of the cystic and common bile ducts in adult German Shepherd dogs using ultrasonography, with a 95% confidence level, to aid in interpreting results and making clinical decisions. This cross-sectional descriptive study involved 12 adult German Shepherd dogs (6 males and 6 females) with an average weight of 24.37 ± 3.65 kg and a mean age of 2.40 ± 0.495 years. Ultrasonography was performed with the dogs positioned in dorsoventral, left lateral, and right lateral recumbency during the inspiratory phase of breathing. Anatomical studies were conducted following anesthesia and during surgery for each dog. According to the ultrasonography results, the mean diameter of the cystic duct at the level of the gallbladder was 4.17 ± 0.58 mm, while the mean diameters of the common bile duct at the hepatis porta and major duodenal papilla levels were 3.23 ± 0.48 mm and 3.14 ± 0.63 mm, respectively. The diameter of the cystic duct at the gallbladder level was greater in males than in females, whereas the mean diameter of the common bile duct at the hepatis porta and major duodenal papilla levels was larger in females than in males; however, these differences were not statistically significant (P > 0.05). The precise standards obtained in this study can be utilized to interpret findings and make clinical decisions regarding the normal and abnormal diameters of the cystic and common bile ducts in adult German Shepherd dogs.
