[Results of laparoscopic pelvic exenterations].

Objective: To analyze clinical outcomes after pelvic exenteration for advanced primary or recurrent pelvic cancer.

Material And Methods: We analyzed the outcomes in 35 patients after pelvic exenteration for advanced primary or recurrent pelvic cancer (gynecological cancer, urologic cancers, colon cancer). There were 3 (8.57%) men and 32 (91.43%) women. Mean BMI was 26 kg/m.

Results: Total exenteration was performed in 10 (28.57%) patients, anterior exenteration - 18 (51.43%) patients, posterior exenteration - 7 (20.0%) patients. Intraoperative complications (damage to the common iliac vessels) occurred in 1 (2.86%) patient. Mean surgery time was 280 minutes (range 180-600), mean intraoperative blood loss - 400 ml (range 100-2000). Mean postoperative ICU-stay was 24 hours. Major postoperative complications Clavien-Dindo grade 3-4 were detected in 3 (8.57%) patients. One (2.86%) patient died in 84 days after surgery from multiple organ failure due to progression of disease (Clavien-Dindo grade 5). There were 4 (11.43%) patients with complications Clavien-Dindo grade ≥3. Negative resection margin (R0) was achieved in 32 (91.43%) cases. The follow-up period ranged from 2 to 70 months (median 16.5 months). Overall survival was assessed in 25 patients. Other 10 patients or their relatives did not get in touch and therefore did not participate in assessment of survival. Overall 2-year survival assessed in 6 patients with cervical cancer was 24%. Overall 2-year survival estimated in 8 patients with bladder cancer was 100%. A patient with colon cancer lived for 23 months. Among 2 patients with vulvar cancer, 1 patient died in 25 months after surgery, the second one was followed-up for 11 months. Patients with primary multiple tumors were followed-up for 10-21 months. Overall 1-year survival was 100%. One patient died after 21 months.

Conclusion: Analyzing own findings and world literature data, we can conclude that laparoscopic technique ensures better intra- and postoperative results compared to standard laparotomy. However, there are insufficient data to confirm superiority of laparoscopic approach regarding oncological results.
