  • anus
  • The anal sacs are located on either side of the anus just under the skin at the 4 o clock and 8 o clock positions. (maxshouse.com)
  • This occurs because the nerves that control the anus are near the anal sacs and may be damaged during surgery. (maxshouse.com)
  • The anal sacs are located at the 4:00 and 8:00 positions around the anus, embedded in the muscle of the anal sphincter (the muscle that closes the anus). (petplace.com)
  • Your pup has two pea-sized anal sacs on either side of his anus in the 4-o'clock and 8-o'clock positions, according to PetEducation.com. (dailypuppy.com)
  • lymph
  • For dogs with AGASAC metastatic to the sublumbar lymph nodes, the overall median survival time is 551 days with median survival times of 358 days if treated with anal sacculectomy alone (i.e., sublumbar lymph nodes are not excised), 546 days if treated with anal sacculectomy and sublumbar lymph node excision, and 1927 days if treated with anal sacculectomy, sublumbar lymph node excision, and chemotherapy. (animalcancersurgeon.com)
  • Excision of the sublumbar lymph nodes results in a significant improvement in survival times over anal sacculectomy alone, and the addition of chemotherapy results in a significant improvement in survival times over surgery alone. (animalcancersurgeon.com)
  • becomes
  • When the abscessed material overflows the sac or the duct leading to the sac becomes obstructed, the skin over the sac breaks open, and the pus drains onto the skin. (maxshouse.com)
  • These sacs contain an oily secretion that is emitted when your dog defecates or when he becomes excited. (dailypuppy.com)
  • feces
  • A small amount of anal fluid is usually squeezed out by muscular contractions whenever the cat passes a bowel movement, providing a distinctive odor (or individual 'scent signature') to the feces. (vcahospitals.com)

  • Apocrine gland anal sac adenocarcinomas first appear as small lumps associated with one of the anal sacs (rarely bilateral), but they can grow to a large size. (wikipedia.org)
  • Apocrine gland anal sac adenocarcinomas also have a tendency to metastasize to the regional lymph nodes, spleen, and eventually lungs and, less commonly, bones. (wikipedia.org)
  • rupture
  • Left untreated, the pressure will continue to build until eventually the overlying skin bursts open, allowing the pus to drain out in a condition called an anal sac rupture . (vcahospitals.com)
  • Sometimes an abscessed anal sac will rupture on its own. (wordpress.com)
  • sacculectomy
  • Excision of the sublumbar lymph nodes results in a significant improvement in survival times over anal sacculectomy alone, and the addition of chemotherapy results in a significant improvement in survival times over surgery alone. (animalcancersurgeon.com)
  • diarrhea
  • In some cases, the cat will have an episode of diarrhea or digestive upset a week or two before the clinical signs of anal sac disease become evident. (vcahospitals.com)
  • yolk
  • its eggs are fertilised internally and remain in the uterus where the developing foetus feeds on the large yolk sac. (wikipedia.org)
  • They consume their yolk sacs and will die if they do not reach the sea within about seven days. (wikipedia.org)
  • It has a viviparous mode of reproduction, featuring an unusual form of oophagy in which the developing embryos consume ova or egg fragments released by the mother and use the yolk material to replenish their external yolk sacs for later use. (wikipedia.org)
