[Postoperative morbidities after modified posterior pelvic exenteration for ovarian cancer]

Complication and survival analysis of cytoreduction surgery with modified posterior pelvic exenteration in the surgical treatment of the ovarian malignant tumor.

A retrospective monocentric study between 2000 and 2013 in Rhone-Alpes cancer treatment center. One hundred and fifty-two patients with ovarian cancer and treated by surgery with modified posterior pelvic exenteration were included. Complication in the 30 days after surgery was analysed by the Clavien-Dindo classification.

In our study, rate of global complication was 62.5% with a morbidity rate of grave complication of 7.9%. Our rate of complete resection was 82.2%. Three fistulas (2.2%) were found. On average, there was 6.6±1.8 (2-11) surgery gesture associated with Hudson resection during surgery. In univariate analysis, there was a statistic significant association between complication from the rank II of Clavien-Dindo classification and supraradical surgery, post-chemotherapy surgery, recurrent surgery, the resection of a diaphragmatic dome, and the partial gastric resection. This association was also observed with the number of surgical gesture associated with Hudson resection.

The main prognostic surgical factor in ovarian cancer is to obtain a no macroscopic residual disease. The modified posterior pelvic exenteration allowed to obtain it. Our study demonstrates a low rate of grave complication further to this type of surgery.
