Miotomy is the most common operation for the treatment of achalasia of the esophagus. The most important complication of this operation is gastro-esophageal reflux, and controversy exists in the choice of a thoracic or abdominal approach to this operation. From 1974 until 1988, our group performed 45 miotomies for achalasia of the esophagus. Follow-up was obtained in 82% of the patients. The thoracic approach was used in 21 cases (tor), and 24 patients were operated through an abdominal approach (abd). All the miotomies had an anti-reflux procedure associated. Post-operative evaluation consisted of: clinical score determination; endoscopy with biopsy; manometry; 24 Phmetry. The clinical score revealed that 47% of the patients in the group tor were asymptomatic, and in the group abd this rate was 53%. Absence of macroscopic esophagitis was registered in 75% of the patients in the group tor, and in 91% in the group abd. Microscopic esophagitis was observed in 42% of the cases in the group tor, and in 45% of the group abd. Manometry revealed a low pressure in the inferior esophageal sphincter in 90% of the cases of the group tor, and in 80% of the group abd. Pathological gastro-esophageal reflux, detected by 24 h Phmetry, was present in 29% of the group tor, and in 36% of the group abd. The results in these two groups were very similar, uniformly favourable, and without evidence of superiority of either operation. The choice of a thoracic, or abdominal approach should depend on associated factors such as patient age, respiratory disease, etc.

A 57-year-old man who had been complicated with achalasia for thirty years was admitted because of back pain and low grade fever. Chest X-p and Chest CT showed consolidation in the left lower lung field. His respiratory condition was diagnosed as lung abscess preoperatively. After systemic chemotherapy, surgical management was done for both achalasia and this inflammatory respiratory disease. In the operation by left thoracotomy, it was revealed that this case had empyema, not lung abscess. Thus decortication of left lung and esophagomyotomy were performed simultaneously. In the treatment of achalasia, respiratory complications due to aspiration may appear. In addition, it is sometimes difficult to distinguish empyema from lung abscess preoperatively. Therefore much care should be taken during operation in order to treat these respiratory diseases.

H-type tracheoesophageal fistula (TEF) may lead to chronic respiratory disease if the diagnosis is delayed. Long-standing fistula causes esophageal distention which is named as pneumoesophagus or megaesophagus and possibly affects the motility of the esophageal body which may also be encountered as a part of tracheoesophageal anomalies. Both dysmotility and megaesophagus may mimic achalasia radiologically and the patient may be advised an unnecessary esophagocardiomyotomy. The authors report a 15-year-old adolescent with H-type TEF who has been diagnosed during investigations for chronic respiratory disease due to presumptive diagnosis of achalasia. The authors emphasize that a complete anatomical and functional evaluation of the upper gastrointestinal tract should be done before recommending operation for achalasia in patients with chronic respiratory disease. H-type TEF should be investigated to avoid unnecessary cardiomyotomy.

Aerodigestive diseases, hybrid disorders representing a pathologic link between respiratory and alimentary tracts, may manifest with respiratory signs without gastrointestinal signs. These are underdiagnosed in dogs due to poor clinical recognition and diagnostic limitations. We hypothesize that a subset of dogs presenting for cough without gastrointestinal signs would have occult aerodigestive disorders identified using videofluoroscopic swallow study (VFSS). Data were retrospectively obtained from 31 client-owned dogs presenting for cough, with thoracic radiographs, and a VFSS between April 2015 and December 2017. Exclusion criteria were cough of cardiac origin or gastrointestinal signs within 6 months. Swallow study parameters included pharyngeal/esophageal motility, laryngeal obstruction/defects, penetration-aspiration, reflux, excessive aerophagia, megaesophagus (ME), lower-esophageal sphincter achalasia-like syndrome (LES-AS), and sliding hiatal hernia (HH). The median (interquartile range) duration of cough was 4 (2-8) months. Thoracic radiographs were unremarkable in 11 dogs, with aspiration pneumonia suspected in seven. In 25/31 dogs (81%), VFSS abnormalities were detected and some dogs had more than one defect: pharyngeal (n=10) or esophageal hypomotility (n=10), reflux (n=9), penetration-aspiration (n=8), excessive aerophagia (n=6), laryngeal obstruction (n=3), ME (n=3), HH (n=2), and LES-AS (n=1). A respiratory disorder causing cough was identified in 17 dogs with VFSS abnormalities (laryngeal obstruction/defect and airway disease including chronic or eosinophilic bronchitis, tracheal/mainstem bronchial collapse, bronchiectasis, and bronchomalacia). An alimentary disorder identified on VFSS in absence of a discrete respiratory disorder causing cough was diagnosed in eight dogs. In conclusion, canine aerodigestive disorders can manifest as cough without alimentary signs. VFSS is a useful diagnostic to determine the contribution of esophageal/gastrointestinal pathology in dogs with cough.
