Abstract

OBJECTIVE

To report perioperative characteristics and outcome following bilateral, single-session, laparoscopic adrenalectomy (BSSLA) in dogs.

ANIMALS

Client-owned dogs (n = 6).

CLINICAL PRESENTATION AND PROCEDURES

Medical records were reviewed and perioperative data collected, including preoperative diagnostic imaging, operative details, complications, and need for conversion to open laparotomy. Bilateral, single-session, laparoscopic adrenalectomy was performed on the right or left side with a standard 3- or 4-portal transperitoneal technique. The dog was repositioned to contralateral recumbency, and laparoscopic adrenalectomy was repeated. Follow-up information was collected by telephone interviews with the owners and/or referring veterinarian.

RESULTS

Median age and weight of dogs were 126 months and 14.75 kg, respectively. Contrast-enhanced CT (CECT) was performed in all dogs. Median maximal tumor diameter was 2.6 and 2.3 cm for the right and left-sided tumors, respectively. Median surgical and anesthesia times were 158 and 240 minutes, respectively. Conversion to open laparotomy was performed in 1 dog following renal vein laceration during initial adrenalectomy. Left adrenalectomy and ureteronephrectomy were performed, and the right adrenal tumor was left in situ. Cardiac arrest occurred in 1 dog following initial adrenalectomy (left); however, the dog was resuscitated successfully, and contralateral laparoscopic adrenalectomy was performed without complication. All dogs survived to hospital discharge. Follow-up ranged from 60 to 730 days (median, 264 days) for dogs that successfully underwent BSSLA.

CLINICAL RELEVANCE

BSSLA was associated with favorable outcomes in this cohort of dogs. Laparoscopy may be considered in dogs with bilateral, modestly sized, noninvasive adrenal tumors.

Abstract

OBJECTIVE

To report perioperative complications and client-perceived outcome following laparoscopic surgical treatment for sliding hiatal hernia (SHH) in dogs.

ANIMALS

Client-owned dogs (n = 9).

METHODS

Medical records were reviewed and perioperative data collected including preoperative diagnostic imaging, operative details, complications, and need for conversion to open celiotomy. A single-incision, multicannulated port was inserted in the subumbilical region followed by placement of an additional 2 or 3 instrument portals. Hiatal plication, esophagopexy, and left-sided gastropexy were performed laparoscopically. Follow-up information was collected with telephone interview with the owners and/or referring veterinarian. A standardized questionnaire was completed by dog owners postoperatively.

RESULTS

Intraoperative pneumothorax occurred in 5 of 9 (55.6%) dogs and resulted in conversion to open celiotomy in 2 (22.2%) dogs. In 4 dogs, pneumothorax was suspected to be the result of progressive leakage of capnoperitoneum through the suture bite holes of the esophageal hiatal plication sutures. Hiatal plication was performed using intracorporeal simple interrupted sutures (n = 4) or a simple continuous pattern with barbed suture (4). Esophagopexy was performed using barbed suture in all dogs. Gastropexy was performed using a total laparoscopic technique (n = 4) or laparoscopic-assisted technique (3). Using a standardized questionnaire, dog owners perceived a postoperative improvement in regurgitation after eating and regurgitation after excitement/increased activity.

CLINICAL RELEVANCE

Laparoscopic treatment of SHH resulted in owner-perceived improvement in clinical signs. Intraoperative pneumothorax occurred in a high proportion of dogs but did not result in long-term sequelae.
