Surgical treatment of a distal oesophageal stricture by mucosal radial incision and dilation in a kitten with secondary megaoesophagus

Abstract

Case summary A 7-month-old intact female Maine Coon cat was presented with a 2-month history of regurgitations. Contrast radiographic and endoscopic examinations revealed a diffuse megaoesophagus secondary to a severe lower oesophageal stricture. An epiphrenic diverticulum was noted. Endoscopic balloon dilation was unsuccessful. Gastrotomy was thus performed in order to incise the oesophageal wall radially along the stricture site, and then to dilate the stricture. A diameter of 20 mm was reached. With the aim of preventing stricture recurrence, submucosal injections of triamcinolone acetonide were performed. An 18 Fr oesophagogastric feeding tube was placed and a left gastropexy was performed in order to exert some traction on the gastroesophageal junction, with the aim of reducing the oesophageal diverticulum. Twelve months postoperatively, clinical signs had completely resolved and follow-up radiographs revealed marked improvement of the oesophageal dilatation. Relevance and novel information Lower oesophageal strictures should be considered when evaluating regurgitations or megaoesophagus in a kitten. Surgical mucosal radial incision is a therapeutic option in cases of lower oesophageal stricture refractory to balloon dilation, and can lead to a marked improvement of clinical signs and of the oesophagus diameter leading to clinical success.

Stricture and Megaesophageal in Local Cats

“…ME bawaan dikaitkan dengan disfungsi aferen vagal (Holland et al, 2002). ME yang didapat adalah idiopatik, atau sekunder dari penyakit lain, seperti myasthenia gravis, hypoadrenocorticisim, disautonomia, polyradiculoneuritis, hipotiroidisme, polimiopati, dan kanker esofagus, gastrooesophageal reflux (GOR) (Alasia et al, 2021), dan Striktur esofagus (Kurtz et al, 2021). Myasthenia gravis adalah penyebab paling umum dari ME sekunder dan telah dilaporkan bahwa titer antibodi reseptor anti-asetilkolin positif ditemukan pada 26% anjing ME tanpa kelemahan otot umum (McBrearty et al, 2011).…”
