Trichobezoar

TL;DR. Trichobezoar je hustá masa prehltnutej srsti, ktora moze upchat zaludok kralika; naliehave, lebo kraliky nezvracaju.

Srst sa v zaludku zhlukuje a moze zablokovat vystup do tenkeho creva.

Co to je?

Kompaktna gulicka srsti v zaludku. Kralik nezvracia. Obstrukcia pyloru: dehydratacia, sok a smrt.

Priciny a rizikove faktory

Malo dlhej vlakniny; hypomotilita; dehydratacia; nadmerne cestovanie. Dlhosrsti vyssie riziko.

Znamky

• Anorexia (casta)

• Mala, sucha alebo chybajuca stolica (casta)
• Letargia, hrbatenie, napaté brucho (caste)
• Hypotermia, dehydratacia, ubytok hmotnosti (caste)

Hrbatenie signalizuje bolest brucha.

Diagnostika

Opatrna palpace (krehka pečen). RTG. Definitivne potvrdenie casto chirurgicke.

"Although definitive diagnosis of trichobezoar cannot be made without surgical exploration, a tentative diagnosis can be made based on history, clinical signs, palpation of an abdominal mass in the vicinity of the stomach, and contrast radiography, especially with fluoroscopy."

"Radiographs are useful in assessing the size of the trichobezoar and its movement. Barium as a contrast agent must be used cautiously in animals that depend on cecal digestion."

Liecba

Bez uplnej obstrukcie: tekutiny, Metoclopramide (nikdy pri uplnej obstrukcii), analgezia, krmenie striekackou.

Uplna obstrukcia: urgentna gastrotomia.

Prognoza

Dobra pri vcasnom zachyteni. Opatrna pri uplnej obstrukcii, hypotermii alebo soku.
