Unexpected malignancies after laparoscopic-assisted supracervical hysterectomies (LASH): an analysis of 1,584 LASH cases.

OBJECTIVE

The objective of this research was to identify the rate of unexpected malignancies after laparoscopic-assisted supracervical hysterectomies (LASH) and describe the therapy regime.

METHODS

The research is based on a retrospective chart analysis of patients undergoing a simple hysterectomy in the gynecological endoscopy department of a general hospital in Germany.

RESULTS

2,577 simple hysterectomies conducted between March 2005 and March 2010 were sub-classified in different types of hysterectomies (vaginal-, abdominal-, total-, abdominal supracervical hysterectomy, LAVH, and LASH). This study focuses on the LASH sub-group of 1,584 patients and does not make any comparisons to other operative approaches. Out of the 1,584 patients, 87.8 % (n = 1,391) received preoperative screening to exclude dysplasia or malignancy based on the policy of the German Association for gynecology and obstetrics (DGGG). The screening includes cytology (Pap-smear) and preoperative ultrasound of the uterus or dilatation and curettage (d&c). Unexpected malignancies were found in 0.25 % (n = 4) of the patients pre-screened according to DGGG protocol. Out of the four malign patients, two had endometrial cancer. Two patients had leiomyosarcoma.

CONCLUSION

The study shows that there is a small probability of unexpected malignancies even in correctly pre-screened patients for LASH procedures. Yet in the short-term (28-52 months), malign patients remain recurrence free after treatment. LASH is therefore a good procedure for assumed benign disease.
