OBJECTIVE: To determine the frequency and types of paramedian incisional complications after prophylactic laparoscopy-assisted gastropexy (LAG) in dogs and to evaluate potential risk factors for complications.

STUDY DESIGN: Multi-institutional retrospective study.

ANIMALS: Client-owned dogs (N = 411).

METHODS: Records for dogs that underwent single-incision-port laparoscopy-assisted gastropexy (SIPLAG) or multiple-port laparoscopy-assisted gastropexy (MPLAG) at five veterinary referral hospitals were reviewed. Information regarding signalment, surgical procedures, perioperative care, and incisional complications was collected. Follow-up information was obtained by review of medical records and/or communication with owners. Potential risk factors for complications were examined statistically.

RESULTS: Paramedian incisional complications were observed in 78 of 411 (19%) dogs. The most common complication was seroma formation, which occurred in 51 (12.4%) dogs. Surgical site infections were observed in 16 (3.9%) dogs, and dehiscence or development of excessive scar tissue at the incision site were each observed in nine (2.2%) dogs. Complications resolved with conservative treatment in 75 of 78 (96.2%) dogs and with surgical treatment in three of 78 (3.8%) dogs. The odds of complications were approximately twice as high in dogs undergoing SIPLAG than in dogs undergoing MPLAG (odds ratio, 2.03; P = .006).

CONCLUSION: Minor paramedian incisional complications, particularly seroma formation, were frequently observed after LAG. Most complications were successfully managed conservatively. Single-incision-port laparoscopy-assisted gastropexy was associated with a higher complication rate compared with MPLAG.

CLINICAL SIGNIFICANCE: Owners should be informed that there is a relatively high rate of minor paramedian incisional complications after LAG. The risk of complications appears to be higher for SIPLAG than for MPLAG.
