[Is the hysteroscopy the right choice for therapy of placental remnants?].

OBJECTIVE

The evaluation of the effectiveness and safety of hysteroscopic management of residual trophoblastic tissue and to verify the miniinvasivity with the second-look hysteroscopy.

DESIGN

Prospective study.

SETTING

Department of Gynecology and Obstetrics, First Faculty od Medicine, Charles University and General Teaching Hospital, Prague.

METHODOLOGY

From 11/2007 to 6/2011, 58 patiens with abnormal uterine bleeding longer than 6 weeks after delivery or abortion underwent ultrasound examination with fading of hyperechogenic content larger than 15mm in AP projection. There was the bipolar resectoscopic system used under general anestesia. Second-look office hysteroscopy was recommended to all patiens 4-6 weeks after a primary procedure.

RESULTS

Median operative time was 15 (7-36) minutes, median time of hospitalisation was 7.1 hours. In four patients was necessary to divide the procedure into two phases (after 14 days). There was no serious uterine bleeding or inflamation in our study group. Only one serious surgical complication was registered: an uterine perforation in patient after 2 cesarean sections, there was the laparoscopic suture provided. The second-look hysteroscopy was provided in 45 patients (77.6%). There was normal intrauterine finding in 16 (35.6%) patients, in 29 patients (64.4%) a small residual trophoblastic tissue was resected. There was no secondary intrauterine adhesive process described.

CONCLUSION

Hysteroscopic resection is a safe and efficient operative technique, which is suitable for management of larger trophoblastic tissue left after delivery or abortion.
