A 6-year-old male neutered domestic cat presented with esophageal obstruction and underwent endoscopic balloon dilation; however, the esophagus was perforated during the procedure. Thoracotomy was performed to enable visualization of the condition of the esophagus. Extensive esophageal stenosis was observed, and it was considered impossible to remove the stenosis and anastomose the esophagus. Therefore, a Nelaton catheter (NC) was passed through the lumen of the stenosis site and was used as a mold to maintain the esophageal lumen, enabling the passage of saliva. The NC was left in place in the esophagus for 3 months while the cat was fed through a gastrostomy tube. After removal of the NC, the cat was able to eat soft food without regurgitation and/or vomiting, and has survived for more than 3 years. The use of a NC to reconstruct the esophageal lumen may be a good option in a cat with life-threatening esophageal constriction.
A 10-year-old spayed female Golden Retriever was referred for hindlimb lameness. A firm mass was palpated over the right caudal pelvis. Computed tomography revealed an osteolytic bone region and an associated periosteal reaction in the ischium, including the acetabulum. The histological diagnosis was sarcoma of unknown origin. A mid-to-caudal partial hemipelvectomy was performed to remove the mass. Femoral head and neck osteotomy was performed to allow hindlimb preservation.Following surgery, the dog regained satisfactory hindlimb use over time and was alive for 821 days with no recurrence or metastatic disease. This report indicates that mid-to-caudal partial hemipelvectomy with femoral head and neck osteotomy is technically feasible and allows for tumor control with preservation of the hindlimb and its function.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
