INTRODUCTION
Esophageal diverticula are uncommon disorders in dogs, which may be classified in congenital or acquired.
OBJECTIVES
To describe esophageal diverticulum in 4.6 months of age, 17 kg, female German Shepherd dog.
METHODS
The dog was admitted due to episodes of emesis, apathy, and discharge nasal and ocular for 3 days.
The owner suspected foreign body ingestion.
Physical examination revealed hyperthermia and
harsh lung sounds were heard. Survey radiography
of the thorax radiographs showed a gas-filled large circular dilation (10.2 x 8.2 cm) located in the cranial mediastinum, esophagus filled with gas, and alveolar pattern compatible to aspiration pneumonia. A contrast radiographic study and computed tomography revealed esophageal diverticulum in cranial region of the thorax and mild megaesophagus along the thoracic esophagus. Esophageal endoscopy also confirmed the diverticulum, but mucosa surface had no abnormality. Left intercostal thoracotomy at the second space was conducted under general anesthesia. The diverticulum was identified, the diverticular pouch was resected, and restoration of the esophageal wall was done by manual two-layer closure.
RESULTS
A contrast radiographic examination performed 10 days after surgery showed no signs of suture-line leak, but a cranial residual portion of the diverticulum was present. A gastrostomy feeding tube was maintained during this post-operative period. The animal recovered without complications, and the clinical signs of dysphagia and pneumonia had ceased. After 2 months after surgery, contrast radiographic examination showed improvement of the megaesophagus. However, the owner was instructed to feed the dog in an elevated position.
CONCLUSIONS
Probably this esophageal diverticulum was associated with esophagus weakness.

INTRODUCTION
Perineal hernia (PH) is a complex disease in dogs. The recurrence of the PH after standard intervention often occurs and with more complicated problem involving bilateral with ventral PH. A suitable method to solve the bilateral with ventral PH is needed.
OBJECTIVES
To evaluate a new surgical technique for correction of bilateral with ventral PH using polyethylene (Leader line) in male dogs.
METHODS
Twelve dogs (Body weight mean 10.2+/- 5.6 kg) had swollen mass at both side of anus and alimentary tenemus. These dogs were diagnosed with bilateral with ventral PH using rectal palpation. Six of the twelve dogs had recurrent after correction with standard surgical technique and other six dogs were diagnosed with bilateral and ventral PH for the first time. The PH were treated with modified sacroischial suture (MSS), which covered the hernia defect. The lateral line of sacroischial suture were sutured to external anal sphincter muscle and connected from both sacroischial suture by lower line to cover the ventral defect of the pelvic floor. All dogs were regularly monitored for 2 years.
RESULTS
All dogs had no complication in the first 14 days after the operation. All dogs were free from bilateral PH without related complication throughout a 2-year period.
CONCLUSIONS
Results of the present study suggest that MSS is an effective surgical method for correction of bilateral with ventral PH in dogs, especially with a presence of thin or friable perineal diaphragmatic muscles.
