    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.
