OBJECTIVES: To compare the incidence and potential risk factors of trocar site hernia formation in women undergoing robotically assisted versus standard laparoscopic staging (RBT vs. LSC, respectively) for endometrial cancer. METHODS: We retrospectively identified all patients who underwent MIS staging for endometrial cancer at our institution from 01/09-12/12. Data collection involved the review of all operative notes, postoperative follow-up visit notes, and postoperative imaging reports. Appropriate statistical tests were used. RESULTS: We identified 760 eligible patients (LSC, 193; RBT, 567). The overall median age was 61years (range, 33-90). The median BMI was 28.5kg/m2 for LSC (range, 16.6-67.6) and 29.5kg/m2 for RBT (range, 17.9-66) patients (p=0.8). A trocar site hernia developed in 16 patients (2.1%)-5 (2.6%) of 193 LSC and 11 (1.9%) of 567 RBT patients (p=0.6). Median time to hernia diagnosis was 13months (range, 5-20.5) and 18months (range, 3-49), respectively (p=0.5). All hernias in the LSC cohort developed at the camera trocar site. In the RBT cohort, 10 developed at the camera trocar site and 1 at a lateral trocar site. Only BMI was associated with the development of hernias. A hernia was diagnosed in 7 (6.9%) of 101 patients with a BMI ≥40kg/m2 compared with 9 (1.4%) of 659 with a BMI <40kg/m2 (p=0.001). CONCLUSION: MIS for endometrial cancer is associated with a low rate of trocar site hernia formation, with similar rates associated with RBT and standard LSC. Higher BMI is associated with the development of postoperative trocar site hernias.
