Results suggest that a 2-cm lateral margin and a deep margin of 1 fascial plane appear to be adequate for complete excision of grade-I and -II MCTs in dogs.

A high mortality rate was associated with adrenalectomy in dogs; however, those that survived until discharge from a hospital had long survival times. Preoperative factors associated with a shorter survival time were weakness or lethargy, thrombocytopenia, increased BUN concentration, increased PTT, increased AST activity, and hypokalemia. Studies are needed to evaluate how treatment for these factors may affect or change outcome after adrenalectomy. Dogs with adrenal masses that require concurrent nephrectomy and cause intraoperative hemorrhage have a guarded prognosis.

Excision with a 2-cm lateral margin and a deep margin of 1 fascial plane may result in satisfactory excision of grades I and II MCTs in dogs, with recurrence rates similar to those reported previously. Use of these margins may minimize complications associated with larger local tumor resection.

The difference between blood and peritoneal fluid glucose concentrations should be used as a more reliable diagnostic indicator of septic peritoneal effusion than peritoneal fluid glucose concentration alone.

This retrospective study provides information that may aid the surgeon in the diagnosis and treatment of bile peritonitis.
