The uterus may be removed by two methods. In one, access is obtained to the uterus through an incision in the belly-wall; this is termed abdominal hysterectomy. In the other, the whole uterus is extirpated through the vagina, and on this account it is termed vaginal hysterectomy or colpo-hysterectomy. The abdominal method of removing the uterus may be performed in two ways:-- In one the body of the uterus and a portion of its neck is removed; this is called subtotal hysterectomy (or supravaginal hysterectomy). In the other the body of the uterus and the whole of its neck are excised: this is total hysterectomy (or panhysterectomy). The ovaries and Fallopian tubes may, or may not, be removed, according to the disease for which the operation is undertaken. This is a matter which will receive ample consideration later on (see p. 56). For the satisfactory performance of abdominal hysterectomy the Trendelenburg position is necessary. SUBTOTAL HYSTERECTOMY The abdomen is opened by the median subumbilical incision; but when the operation is performed for the removal of large tumours it will frequently require extension above the umbilicus. The operator should never allow himself to be embarrassed by a small incision. As soon as the peritoneal cavity is reached, the surgeon introduces his hand and carefully makes out the nature of the case, the presence or otherwise of adhesions, other tumours, and the relation of the fibroid to the uterus, and determines whether it is impacted in the pelvis. The uterus is then carefully lifted out through the incision, or drawn out with the assistance of a volsella; the intestines and omentum are isolated from the pelvis with a large warm dab.
