Similar regression of ME and hiatal hernia after resolution of concurrent nasopharyngeal stenosis has been reported in a cat 3) , suggesting that ME can occur because of pharyngeal obstruction with not only a mass but also stenosis. The exact mechanism of ME development secondary to pharyngeal mass or stenosis is unknown, but chronic aerophagia 2) or negative intrapleural pressure caused by increased inspiratory effort 3) is thought to play a role in progression of ME.…”

Summary: An 8-month-old female cat presented with a 1-month history of open-mouth breathing and intermittent regurgitation. Contrast radiography revealed megaesophagus (ME) with a large pharyngeal mass. The mass was removed by gentle traction under general anesthesia, after which the ME resolved within 9 days. The mass was diagnosed as a nasopharyngeal polyp based on clinical and histopathological findings. A similar polyp recurred 50 days postoperatively, and was also removed by traction followed by four treatments with methylprednisolone acetate. The cat remained asymptomatic for 9 months after the second surgery. This report demonstrates that ME resulting from a nasopharyngeal polyp may resolve spontaneously after polyp removal, but post-surgical glucocorticoid therapy may also be needed to decrease the chance of recurrence.

“…Congenital hiatal hernia, as other congenital malformations (Pisoni et al 2012;Tremolada et al 2013) is an uncommon abnormality in dogs and rare in cats, but various reports are available in the literature (Gaskell et al 1974;Teunissen et al 1978;Peterson 1983;Ellison et al 1987;Miles et al 1988;Prymak et al 1989;Bright et al 1990;Williams 1990;Brinkley 1990;White 1993;Callan et al 1993;Auger and Riley1997;Hardie et al 1998;Lorinson and Bright 1998;Sivacolundhu et al 2002;Rahal et al 2003;Kirkby et al 2005;Owen et al 2005;Ardnt et al 2006;Baig et al 2006;Keeley et al 2008;DeSandre-Robinson et al 2011), most of which are congenital, such as, apparently, the case described in the present report. Despite the several cases reported, the pathogenesis is not completely understood and, similarly, the therapeutic protocol has not been standardised.…”

A case of surgical resolution of type I or "sliding" hiatal hernia is reported. A seven-month-old kitten was presented because of abdominal discomfort, accelerated breathing after eating and chronic vomiting. The clinical examination was unremarkable. Thoracic radiographs and gastroscopy led to the diagnosis of type I hiatal hernia. The surgical resolution consisted of hiatal plication, oesophagopexy and left-flank incisional gastropexy. All procedures were carried out using a 6 mm videoendoscope positioned in the stomach to evaluate the right oesophago-gastric junction reduction. One week after surgery there was a recurrence of symptoms and a second laparotomy was performed. During the second surgery additional hiatal plication was necessary and an oesophagopexy was repeated after dissection of the phrenico-oesophageal ligament. Moreover, a new incisional gastropexy was carried out after resolution of the first one. The cat recovered without complications and at oneyear follow-up did show no signs related to the hiatal hernia. This communication reports on possible additional surgical techniques in cases of type I hiatal hernia and contributes to an understanding of the importance of oesophagopexy in cases of hiatus malformation.

“…Currently, there is no published evidence of long-term successful treatment with this technique and it has been reported to have a high rate of recurrence (Coolman et al 1998, Novo & Kramek 1999, Glaus et al 2002. A minimally invasive technique with endoscopy-guided balloon dilatation has also been described (Glaus et al 2002, Boswood et al 2003, Glaus et al 2005, Berent et al 2006, DeSandre-Robinson et al 2011. This technique also has been associated with a high rate of recurrence of the stenosis, and multiple dilatation procedures may be necessary (Glaus et al 2002, Schafgans et al 2012, Berent 2016, Burdick et al 2018 To reduce the risk of recurrent stenosis, the use of metallic or soft stents has been proposed in addition to balloon dilation in order to maintain the nasopharyngeal opening during the healing phase (Novo & Kramek 1999, Berent et al 2008, Cook et al 2013, De Lorenzi et al 2015.…”

Objective To describe the use of extended palatoplasty as treatment of caudal nasopharyngeal stenosis in cats. Materials and Methods CT was used to confirm the diagnosis in cats with clinical signs consistent with nasopharyngeal stenosis. Extended palatoplasty rostral to the tonsils using monopolar electrocautery allowed simultaneous removal of the caudal soft palate together with the stenotic area. Cats were re‐evaluated 2 weeks postoperatively. Telephone interview was used to obtain long‐term follow‐up. Results Six domestic shorthair cats were diagnosed with nasopharyngeal stenosis, with clinical signs of snoring (n=4), stertor (n=4), nasal discharge (n=3) and sneezing (n=1). CT scan identified a soft‐tissue stricture at the level of the caudal nasopharynx in all cats. Other abnormalities included bilateral rhinitis (n=3), retropharyngeal adenomegaly (n=2), unilateral sinusitis (n=1) and bilateral otitis externa with unilateral otitis media (n=1). Excision of the caudal soft palate and the entire stenotic soft‐tissue membrane was successful in all six cats. No pre‐, intra‐ or postoperative complications were observed. Short‐term outcome revealed clinical improvement in all cases. Long‐term outcome revealed no recurrence of clinical signs in four cats. In one cat, occasional sneezing was reported. One cat died 1 month postoperatively for reasons unrelated to the respiratory condition. Clinical Significance Extended palatoplasty was an effective technique to treat caudal nasopharyngeal stenosis and provide improvement of clinical signs without postoperative complications in all cases.
