Background: Port-site metastasis is a known complication of laparoscopic surgery, although it has been described less in robotic surgery. There are limited reports of such occurrences in current literature.
Cases: Two patients underwent robotic-assisted total laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and lymph node dissection for stage IA endometrial cancer. One patient's surgery was complicated by uterine perforation but the other surgery was uncomplicated. Both patients had development of isolated port-site metastasis and required resection followed by chemotherapy and radiation.
Conclusion: Port-site metastasis is a surgical complication with an unclear etiology. There are no clear data to suggest a lower incidence with robotic surgery. Patients at low risk for recurrence still may experience development of port-site metastasis.
