Objective:
To address the consequences of surgical curettage following failed medical abortion.
Methods:
A retrospective case-control study was performed in a tertiary gynecologic department. The case group comprised 104 women who underwent surgical curettage following failed medical abortion; the control group included 104 women who underwent early surgically induced abortion. Clinical characteristics and surgical findings were examined. The extent of inflammation was quantified following immunohistochemical staining for cell-surface markers characteristic of T lymphocytes, B lymphocytes, and macrophages. The extent of necrosis was evaluated morphologically.
Results:
Abnormal findings during surgical curettage were significantly more prevalent among women in the case group than in the control group (10.6% versus 1.9%; P=0.019). The most frequent abnormality in the case group was the presence of intimately adherent products of conception, necessitating sharp curettage. The extent of inflammation (represented by increased numbers of T and B lymphocytes) was greater in the case group than in the control group (P=0.046 and P=0.001, respectively), as was the extent of necrosis (P<0.05).
Conclusion:
Curettage following failed medical abortion harbors particular difficulties, which may be attributed to an inflammatory response. The long-term consequences of curettage following failed medical abortion warrant further investigation.
