Fibroids and pregnancy. In a large number of instances in which operations have been undertaken when fibroids complicate pregnancy, they have been performed on an erroneous diagnosis. The tumours when small and placed laterally simulate ovarian cysts; when large and lying high in the abdomen they have been mistaken for renal tumours, and when low in the pelvis they have been regarded as incarcerated ovarian cysts. The variety of fibroid most likely to lead to operation, under the impression that it is an ovarian cyst, is an interstitial fibroid which becomes painful in consequence of undergoing red degeneration. The difficulty which faces the surgeon in this condition is to decide on a safe course.
When the tumour is not likely to cause difficulty it may be wise to close the abdomen. If the tumour is pedunculated and incarcerated, he may be able to extract the tumour and ligature the pedicle without disturbing the pregnancy; a big fibroid invading the broad ligament may be enucleated; a large cervix fibroid will render delivery impossible, and will necessitate hysterectomy.
A study of many recorded cases in which hysterectomy has been performed on account of fibroids complicating pregnancy shows that the operation had been undertaken on account of a great increase in the size of the tumours, the concurrent pregnancy not being discovered until the parts were examined after removal.
Hysterectomy may be necessary at any time during pregnancy; after labour has begun; and during puerpery on account of fibroids. During pregnancy it is a straightforward operation, the subtotal operation being preferable. When it is needed during puerpery it is for septic complications, and there is no greater difficulty in performing hysterectomy then than during pregnancy, but the risk to the patient from sepsis is much greater: therefore total hysterectomy with drainage is advisable.
Fibroids have many times been enucleated from the gravid uterus and the pregnancy has gone successfully to term.
When pregnancy complicated with fibroids goes to term and the tumour occupies the neck or the lower segment of the uterus so as to offer an impassable barrier to the passage of the fœtus, abdominal hysterectomy is a necessity.
