“…The diaphragmatic flap was used in this case to fill up the oesophageal defect and reduce the excessive tension, and it showed a good result. This result is in agreement with previous reports (Richardson, 2005;Paulo et al, 2007).…”

“…For oesophageal reconstruction, various muscle flaps such as diaphragm, pleural, and intercostal muscle flap have been studied as a means of repairing an oesophageal defect and perforation depending on the location of the injury (Bouayad et al, 1992;Jones and Ginsberg, 1992;Richardson, 2005). The diaphragm muscle flap has been used to repair caudal oesophageal perforation in humans (Richardson, 2005) and animals (Paulo et al, 2007). The diaphragm is a strong, elastic and well vascularizated muscle, also resistant to necrosis, and bearer of a good regeneration capability.…”

A two-years-old, intact female, Shih-Tzu dog weighing 5 kg was presented to the Chonbuk Animal Medical Centre, College of Veterinary Medicine, Chonbuk National University, with the history of bone ingestion before two days. The survey radiographs of the thorax revealed a bone at the caudal thoracic oesophagus. An oesophagram was performed which did not reveal any oesophageal leakage or perforation. The left caudolateral thoracotomy was performed and the caudal oesophagus was found partially necrosed, friable and inflamed. The necrosed, friable part was removed and the oesophageal defect was reconstructed using a full-thickness muscle flap collected from the diaphragm. A part of the omentum was mobilized from the abdomen and sutured over the reconstructed site of the oesophagus to aid healing. Oesophagoscopy after nine days postoperatively showed a good adhesion of the diaphragm flap. The patient showed normal activity after 12 days and no complications were observed during a one-year follow up period. The pedicle flap collected from the left hemidiaphragm in addition to the omentum flap can be successfully used to reconstruct the circumferential oesophageal defect.

“…There is also a possibility of using the gastric wall pediculi (Fossum et al 2012) mobilized through the diaphragm. Authors such as Paulo and Wagner (2007) like to use a diaphragmatic pediculus to repair the esophagus wall. In our case we used a knitted polyester prosthesis with small meshes, which is efficient in this type of intervention and very well tolerated both by humans and animals (Muste et al 2011).…”

Use of Dacron prosthesis in esophageal diverticula in a dog – a case report

et al. 2014

A one-and-a-half-year-old male dog of the Caniche breed was examined for repeated regurgitation episodes. At clinical examination food or liquid regurgitation episodes were reported at different times after food ingestion. The esophagus was visualized with the videoendoscope and then examined on liquid barium sulphate. The assessment revealed the existence of two cervically and mediastinally (intrathoracically) located dilatations. The surgical procedure was based on polyester vascular prostheses also used in human vascular surgery. The surgery was performed in two stages with a 4 week interval in between, without the resection of the dilated walls, with the prostheses positioned and fixed in different ways and with very good post surgery recovery. Eleven months after the surgery the dog's health condition was very good. To our knowledge, this is the first report about these procedures which avoid the resection of a portion of the esophagus wall, thus preventing the occurrence of scars or strictures at this level, and prostheses increase the support and stability of the affected esophagus portion. Canine, esophagus, diverticular dilatation, surgeryOne-and-a-half-year-old male dog, Caniche, 6.5 kg, was presented, manifesting repeated food or non food (liquid) regurgitation episodes at different times after food ingestion. A polyester prosthesis was used on the subject. This type of prosthesis features good stability and elasticity, and can work more than 10 years after the implant. It is highly resistant, toxic free, does not cause either intolerance or undesired side effects and reacts well in high flow and high speed areas.Esophagus diseases in dogs are diagnosed based on regurgitation episodes ocurring mostly after eating. Postprandial regurgitation is common in dogs suffering from esophageal diverticulum (Shaw et al. 1997). Esophageal diverticula are either congenital or inherited as dilatation (sack) of the esophageal wall with lower frequency in dogs. Consequently there are only a few reports on this issue world-wide (Hill et al. 1979). Esophageal diverticula are classified as pulsion and traction diverticula (Shaw et al. 1997) with the remark that pulsion diverticula are incriminated in the epiphrenic area (Pearson et al. 1978).Authors such as Qin et al. (2003) and Zhang et al. (2008) used polyurethane artificial stent prostheses covered by chitosan-collagen sponge in dogs for esophagus reconstruction purpose.This report describes the clinical, endoscopic and therapeutic features of a canine patient suffering from double esophageal diverticulum (in the cervical and endothoracic area) in which vascular prosthesis was used for the first time. Case presentationPostprandial regurgitation and vomiting at different times after food ingestion was reported. The portprandial episodes started 3 months before, with a progressive worsening.

“…A porção diafragmática de onde foi obtido o enxerto foi suturada, deixando-se apenas a base aberta, com o intuito de evitar seu estrangulamento. O retalho diafragmático garante rápida angiogenese, e aos 24 dias observou-se epitelização do implante através de endoscopia (PAULO et al, 2007).…”

Dedico este trabalho aos meus pais. Eu sempre os amei tanto, mas só agora, que sou mãe, entendo o quanto me amam. Ao meu marido, meu mestre, meu melhor amigo. Você me deu paz e tranquilidade, esteve do meu lado, mesmo quando isto foi o mais difícil. E aos meus filhos: Nicholas e Christopher, vocês me ensinaram que a felicidade é verdadeiramente infinita e está nas menores coisas. "The power of imagination makes us infinite"
