Percutaneous endoscopic tube gastrostomy in dogs.
Percutaneous endoscopic tube gastrostomy was performed in 10 dogs, using mushroom-tip catheters (16 to 24 F) maintained in place for 5 to 32 days. Dogs were observed daily. Although placement of the catheter was simple and quick, 3 dogs destroyed their catheters. Patency of the catheter was maintained with or without regular flushings with saline solution. Pyrexia (greater than or equal to 39.4 C) developed in 3 dogs, but the rectal temperature returned to base line within 24 hours after catheter removal. After catheter removal, all wounds healed without complication. All dogs were euthanatized. Five were examined radiographically before euthanasia to determine the fate of the mushroom tip after transection of the catheter at skin level between days 5 and 21, and 5 dogs were evaluated at postmortem examination between days 10 and 32. In all dogs, the tip was not present in the gastrointestinal tract by 96 hours after catheter transection. During postmortem examination of the 5 dogs, minimal inflammatory lesions were seen in the gastric tissue. A gastrocutaneous fistula had formed in each dog, resulting in an adhesion between the stomach and peritoneum.
