Objective:
To describe the techniques we have developed to instill chemotherapeutic agents into the pelvic cavity using real-time transvaginal ultrasonographic guidance.
Methods:
This was used for intraperitoneally administered chemotherapy in 11 patients with ovarian carcinoma.
Results:
A total of 38 instillations were done in these patients. The average time for instillation was 23.9 min. No adhesions were associated with this chemotherapy. As for complications, hematuria occurred during 2 (5.3%) instillations. No other complications were observed.
Conclusion:
Real-time ultrasonographically guided transvaginal intraperitoneal chemotherapy can be performed without any catheter systems. This is a safe, reliable, convenient, repeatable, and inexpensive procedure.
