Abstract
Objective: To report the surgical technique and outcome of dogs undergoing laparoscopic adrenalectomy for removal of unilateral noninvasive pheochromocytoma. Study Design: Retrospective case series. Animals: Dogs with unilateral noninvasive adrenal tumors (n=10). Methods: Medical records of dogs that underwent laparoscopic adrenalectomy for histologically confirmed pheochromocytoma were reviewed. Dogs were positioned in lateral recumbency with the table tilted up to create a semi-sternal position. Three or 4 ports were used and dissection of the mass proceeded using a combination of laparoscopic instrumentation, bipolar vessel-sealing devices, and in some cases monopolar electrosurgical probes. Conversion rate, complications, surgical time, hospitalization time, and long-term follow-up were recorded. Results: The procedure was completed without the need for conversion in 9 of 10 dogs. In 1 dog, hemorrhage obscured the visual field and conversion to an open approach was elected. In 5 cases, a 3-port approach was used, and in 5 cases, a 4th port was placed. Median surgical time was 105 minutes (range, 65–250). Intraoperative complications included 1 splenic laceration. Postoperatively, 1 dog developed gastric dilatation-volvulus. All dogs were discharged from the hospital. Median follow-up time was 16.0 months (range, 6.9–38.0). Conclusion: With careful case selection, laparoscopic adrenalectomy for resection of pheochromocytoma was feasible and could be performed efficiently by experienced laparoscopic surgeons.
