Objective: Virtually any port system for single-port laparoscopic surgery is for single usage only. The aim of this study was to trial the novel and completely reusable port X-Cone in order to perform a cholecystectomy by one infraumbilical incision. Methods: Single access cholecystectomies were performed in 9 anesthetized domestic pigs in nonsurvival studies. Only one infraumbilical incision was performed for placing the reusable, multichannel steel port system. A newly developed angulated forceps was used besides regularly used instruments in laparoscopic surgery. Results: The gallbladder was successfully removed in 9 pigs. At postmortem examination, the clips placed on the cystic duct and the cystic artery. No bile leakage was found at the operative field. Conclusion: Single-port cholecystectomy with the reusable X-Cone single-port system is safe and feasible. No additional incisions were needed. The system is ergonomically designed, easy to handle, and the learning curve for cholecystectomy is steep.
