PYLORIC OBSTRUCTION IN A DOG RELATED TO A GASTROTOMY INCISION CLOSED WITH POLYPROPYLENE

A five-year-old male, West Highland terrier was treated for a gastroin testinal foreign body via a gastrotomy incision and enterotomies. The dog was asymptomatic for several months but was eventually re-presente d because of vomiting. Endoscopic and surgical evaluation confirmed a large mass within the pyloric canal that probably resulted from a reac tion to the polypropylene suture material used to Close the original g astrotomy incision. The mass was excised via a Y-U pyloroplasty incisi on and the dog has been free of vomiting for over a year.
