Esophageal disease in cats

Frowde, P.E., et al., Oesophageal disease in 33 cats. Journal of feline medicine & surgery, 2011. 13(8): p. 564-569.

Esophageal disease is reported as uncommon in cats, though there have been few studies to document its frequency. The goal of this retrospective study was to characterize the frequency, presentation, diagnostic means, treatment and outcome of the disorder in cats. Thirty-three of 2,894 cases (approximately 1 %) met the inclusion criteria for the study. Regurgitation and/or vomiting were the most common presenting clinical signs, reported in 27 of 33 cats. Anorexia and weight loss were non-specific signs also noted. Some of the cats referred for perceived vomiting were subsequently discovered to have regurgitation. This finding highlights the importance and difficulty of trying to distinguish between vomiting and regurgitation to aid localization of the problem. Plain radiography is relatively insensitive for esophageal disease and a number of additional diagnostics may be required. A definitive diagnosis was made in 32 of 33 cases, making idiopathic esophageal dysfunction very rare. Recent oral medication (e.g., doxycycline, clindamycin) was the most common cause of esophageal strictures. Therefore, the careful administration of certain oral antibiotics is important. Treatment and outcome of esophageal disease is highly variable. [VT]

Pilling Cats: What is the Best Way?

Bennett AD, MacPhail CM, Gibbons DS et al: A comparative study evaluating the esophageal transit time of eight healthy cats when pilled with the FlavoRx pill glide versus pill delivery treats, Journal of Feline Medicine & Surgery 12:286, 2010.

It is well known that retention of the tablets or capsules of certain drugs (e.g., doxycycline, clindamycin) in the esophagus of the cat can cause inflammation and stricture formation. Current recommendations are that cats should never be given medication "dry", but any pill or capsule should be followed with a food treat or a bolus of water. This study was designed to evaluate the esophageal transit time of tablets and capsules when administered with either the FlavoRx pill glide or Greenies Pill Pockets. The FlavoRx pill glide is a one-step system that delivers the medication and a 3 ml fluid bolus at the same time. Four different medications were evaluated on different days in eight healthy cats. The estimated average esophageal transit time ranged from 16 seconds to 26 seconds. The researchers conclude that both the FlavoRx pill glide and Pill Pockets provide acceptable transit time into the stomach. [SL]

Esophageal Stricture Treatment for Cats

Bissett SA, Davis J, Subler K et al: Risk factors and outcome of bougienage for treatment of benign esophageal strictures in dogs and cats: 28 cases (1995-2004), J Am Vet Med Assoc 235:844, 2009.

Benign esophageal strictures (BES) can be a difficult problem for owners and pets as they can be costly to treat and are associated with a poor prognosis. Up to 30% of the pets affected can only be fed liquid diets long term. The most common cause of BES reportedly is gastrointestinal reflux associated with general anesthesia. Esophageal bougienage is a process of dilation of the esophagus with mechanical dilators. BES in the past has been primarily treated with balloon dilators. The goal of this study was to compare the outcomes of esophageal bougienage to balloon dilation, considering that bougienage can be a more cost effective procedure. Eight cats with BES were evaluated as part of the study. Six of the 8 cats achieved a good outcome with bougienage, defined as a tolerance of solid food with regurgitation less than once a week. Cats with BES were most likely to have a recent history of general anesthesia, vomiting, or gastrointestinal tract trichobezoars (hairballs) than cats in a reference population. In 3 cats with BES, doxycycline induced esophagitis was the suspected cause of the disorder. [VT]

Esophageal Damage From a Hairball

Durocher, L., S. E. Johnson, et al. (2009). "Esophageal diverticulum associated with a trichobezoar in a cat." J Am Anim Hosp Assoc 45(3): 142-146.

This report describes an unusual case of esophageal obstruction and subsequent esophageal diverticulum in a 9-year old, neutered male domestic longhair cat associated with a hairball (trichobezoar). The patient was originally diagnosed with esophageal obstruction secondary to a hairball, and the hairball was removed endoscopically. Nine months later, the cat presented for persistent regurgitation. Contrast radiography with fluoroscopy revealed an esophageal diverticulum at the thoracic inlet with decreased esophageal motility distal to the diverticulum. Esophagostomy revealed the presence of a hairball within the diverticulum that was removed. With medical therapy and a canned diet, the cat did well for 2 months until it died suddenly. [SL]
