Use of the Endo GIA stapler for lung lobectomy in dogs and cats undergoing open thoracic procedures (intercostal, transdiaphragmatic thoracotomy or median sternotomy): A retrospective study of 46 lung lobectomies.

Abstract

OBJECTIVE: To describe Endo GIA stapler use in open approach lung lobectomies. Endo GIA stapler use for open approach lung lobectomies has been validated in cadaveric studies; however, current veterinary literature lacks in vivo studies. STUDY DESIGN: Retrospective study. SAMPLE POPULATION: A total of 33 dogs and four cats (37 cases, 46 lung lobectomies). METHODS: Records from November 2019 to September 2024 at a single institution were reviewed. Dogs and cats that underwent lung lobectomy via thoracotomy (intercostal, transdiaphragmatic) or median sternotomy using Endo GIA staplers were included. Pre-, intra-, and postoperative data were collected. Complications were assessed using the Cook Complication Grading System. Complication rate was analyzed to demonstrate use of Endo GIA staplers in open thoracic procedures. Cases included had a 14-day follow-up at minimum or at death. RESULTS: A total of 46 lung lobectomies (37 cases) were performed using an Endo GIA stapler via open thoracic procedures. No intraoperative complications were noted in 38/46 (82.6%) lung lobectomies. Minor intraoperative complications occurred in 8/46 (17.4%) lobectomies. No major complications occurred. Catastrophic complications occurred in 4/37 (10.8%) cases (4/46 [8.7%] lung lobectomies) postoperatively, likely due to comorbidities. Cases that reached 14-day follow-up, despite one minor postoperative complication of seroma formation, had no complications (32/33, 97%). CONCLUSION: Endo GIA stapler use for open approach lung lobectomies proved to be a valid procedure with minimal complications. The unique properties of the Endo GIA stapler offered an alternative to traditionally used staplers for lung lobectomy. CLINICAL SIGNIFICANCE: Endo GIA staplers can be used for open approach lung lobectomy as a beneficial alternative with minimal complications.
