Objective:
To determine whether the stripping technique by laparoscopy is a tissue-sparing procedure.
Design:
Prospective study.
Setting:
University hospital.
Patient(S):
Forty-two women, 21 to 35 years of age, who had a unilateral ovarian cyst (26 endometriomas, 7 serous, 6 dermoid, and 3 mucinous cysts).
Intervention(S):
Laparoscopic excision of ovarian cysts by using the stripping technique.
Main Outcome Measure(S):
Histologic analysis of the excised specimens was done to evaluate the presence and nature of ovarian tissue adjacent to the cyst wall.
Result(S):
Recognizable ovarian tissue adjacent to the cyst wall was present in 15 of 42 excised specimens (36%). A significant difference was present for endometriomas versus non-endometriosis cysts (ovarian tissue was present in 14 of 26 specimens [54%] vs. 1 of 16 specimens [6%]; P<.005). No specimen showed the normal follicular pattern observed in healthy ovaries.
Conclusion(S):
The stripping technique appears to be a tissue-sparing procedure. In 36% of the cysts, ovarian tissue is excised together with the cyst wall, but this tissue does not show the morphologic characteristics observed in normal ovarian tissue.
