Predictors of Lymphoceles in Women Who Underwent Laparotomic Retroperitoneal Lymph Node Dissection for Early Gynecologic Cancer: A Retrospective Cohort Study.

Background: Lymphoceles could represent a detrimental complication after retroperitoneal lymph node dissection. Our aim was to elucidate predictors of lymphoceles. Methods: Between 2011 and 2017, medical records of consecutive women who underwent laparotomic retroperitoneal lymph node dissection for FIGO stage I or II gynecologic cancer were reviewed. Results: A total of 204 women, including those with lymphoceles (n = 31) and symptomatic lymphoceles (n = 7), were reviewed. According to multivariable analysis, parity (odds ratio = 0.59, p = 0.003), adjuvant pelvic radiotherapy (odds ratio = 2.60, p = 0.039), and peritoneal nonclosure without pelvic drainage (odds ratio = 2.31, p = 0.048) were predictors of lymphoceles. In addition, parity (odds ratio = 0.73, p = 0.03), hypertension (odds ratio = 2.62, p = 0.02), and peritoneal partial closure with pelvic drainage (odds ratio = 0.27, p = 0.02) were predictors of complications. Conclusion: Low parity, adjuvant pelvic radiotherapy, and peritoneal nonclosure without pelvic drainage were associated with increased lymphocele formation. In addition, a lower complication rate was found in the peritoneal partial closure with pelvic drainage group; thus, peritoneal partial closure with pelvic drainage might be suggested for women who undergo laparotomic retroperitoneal lymph node dissection.
