Extraperitoneal Para-aortic Lymphadenectomy by Robot-Assisted Laparoscopy (S, SI, and XI Systems)
Here, we report the use of extraperitoneal para-aortic lymphadenectomy by robot-assisted laparoscopy in one cancer center.
Materials and Methods
Forty-one consecutive patients were described: 31 patients with the S system from Da Vinci and 10 with the Xi system.
Forty-one consecutive patients were analyzed (51 years, BMI 28) with the following types of cancer: cervical cancer (n = 27), endometrial cancer (n = 9), adnexal cancer (n = 4), and vaginal cancer (n = 1). Operative time, estimated blood loss, and the mean number of para-aortic lymph nodes resected were 207.2 (±61.2), 104.8 mL (±126.8 mL), and 19.7 (±10.5), respectively.
There was one failure with pneumoperitoneum in an obese patient without the possibility of transperitoneal para-aortic lymphadenectomy. Two other patients had failure with pneumoperitoneum, but they underwent transperitoneal para-aortic lymphadenectomy by robot-assisted laparoscopy. One patient had hemorrhage lateral to the IMA, so we used extraperitoneal laparoscopy for coagulation (hemorrhage, 600 mL, but no transfusion).
With a follow-up of 33 months, we reported 32% of postoperative complications, such as drainage of lymphocysts, lymphedema, and dysesthesia.
Extraperitoneal para-aortic lymphadenectomy by robot-assisted laparoscopy exhibited rates of failure, preoperative complications, and postoperative complications of 2.5%, 2.5%, and 32%, respectively. Peritoneal marsupialization could be useful to reduce symptomatic lymphocysts, except in cases of macroscopically involved para-aortic lymph nodes.
