ABSTRACT
INTRODUCTION: Para-aortic lymphadenectomy plays a fundamental role in the surgical management of pelvic gynecological cancers. Two laparoscopic approaches exist: the transperitoneal (TP) and the extraperitoneal (EP). The aim of this study was to compare these 2 approaches in terms of surgical outcomes, specially the number of removed lymph nodes according to the surgical technique, and morbidity.
MATERIALS AND METHOD: A single-center retrospective study was carried out at the Lariboisiere University Hospital between January 2011 and March 2020 including all patients who underwent para-aortic lymphadenectomy for the management of a pelvic gynecological cancer (cervix, endometrium, ovary). Univariate and multivariate analysis (logistic regression) were performed to compare the TP and the EP groups.
RESULTS: 143 patients were included: 74 in the TP group and 69 in the RP group. The total duration of surgery was 220.8 minutes in the TP group and 166.4 minutes in the EP group (p<0.001 in multivariate analysis). No significant difference between groups were found in the average total number of lymph nodes removed but there was a statistically significant difference in the average latero-aortic number of lymph nodes removed: 8.5 lymph nodes in the TP group and 11.3 lymph nodes in the group RP (p<0.001 in multivariate analysis). There was no difference between groups in peri and postoperative morbidity.
CONCLUSION: EP para-aortic lymphadenectomy reduces duration of surgery and increases the average latero-aortic number of lymph nodes removed with same morbidity compared to TP para-aortic lymphadenectomy, this confirming its preferred indication in endometrial and in cervical cancers.
