Abstract:

Objective

To assess the therapeutic efficacy of different ultrasound-guided interventions in the treatment of pelvic lymphocysts.

Methods

The data of 36 patients who underwent ultrasound-guided intervention treatment of pelvic lymphocysts after gynecologic carcinoma at the PLA General Hospital from June 2014 to June 2020 were retrospectively analyzed. Ultrasound-guided aspiration, absolute alcohol sclerotherapy, or catheter drainage was utilized in the treatment, and Chi-square tests were conducted to compare the effectiveness rate among different treatments.

Results

The effectiveness rate was 36% (4/11) for ultrasound-guided aspiration, which was effective for the lymphocysts with a size of less than 5 cm with the combined treatment of aspiration and antibiotic indwelling, 62% (8/13) for ultrasound-guided absolute alcohol sclerotherapy, and 83% (10/12) for ultrasound-guided catheter drainage. For the pelvic lymphocysts with a diameter of >10 cm, ultrasound-guided aspiration was ineffective in one case, ultrasound-guided absolute alcohol sclerotherapy was ineffective in two cases, but ultrasound-guided catheter drainage was effective for all the cases. The effectiveness of ultrasound-guided absolute alcohol sclerotherapy was better than that of ultrasound-guided aspiration, and the effectiveness of ultrasound-guided catheter drainage was better than that of ultrasound-guided absolate alcohol sclerotherapy; there was a statistical difference among the three groups (χ2=12.91, P=0.012).

Conclusion

Ultrasound-guided intervention therapy is safe and effective in the treatment of postoperative pelvic lymphocysts. Among the three ultrasound-guided interventional therapies, ultrasound-guided catheter drainage has the best therapeutic efficacy, especially for larger size lymphocysts, and ultrasound-guided aspiration has the worst effectiveness, though it is effective for smaller size lymphocysts anyway.
