Objective: To describe a technique and report complications and outcome for single-port laparoscopic splenectomy in dogs. Study Design: Retrospective study. Animals: Twenty-two client-owned dogs. Methods: Medical records of dogs that underwent single-port laparoscopic splenectomy at 4 veterinary teaching hospitals were evaluated. Commercially available single-port devices were used in all dogs. In all cases, a vessel-sealing device was used to perform a hilar splenectomy. After the procedure was completed, the spleen was exteriorized through the single-port device incision or placed into a specimen retrieval device; enlargement of the incision was required in some cases. Results: Median weight of dogs was 9.9 kg (interquartile range [IQR], 7.0-26.0). Splenectomy was performed because of splenic mass (n=14), diffuse splenic disease (n=4), or as adjunctive treatment for management of immune-mediated disease (n=4). In cases with splenic masses, median maximal diameter of the largest splenic mass was 2.0 cm (IQR, 1.3-2.5). In 6 of 22 cases, mild splenic capsular bleeding occurred during the procedure. Conversion occurred in 6 of 22 cases to either a laparoscopic-assisted approach (n=5) or an open celiotomy (n=1). Reasons for conversion included large splenic dimensions (n=3), adhesion formation (n=1) or poor visualization resulting from abundant intra-abdominal fat (n=1) or hemorrhage (n=1). Heavier body weight was significantly associated with conversion (odds ratio, 1.62; 95% confidence interval, 1.05-2.51), but body condition score, having a splenic mass, splenic mass size, and surgical time were not. Conclusion: Single-port laparoscopic splenectomy is an effective approach for elective splenectomy in dogs. The technique may be well suited to smaller dogs with modestly sized splenic masses or diffuse splenic disease.
