As our patient is anesthetized, we will proceed at once with the operation for the removal of the abdominal tumor, which you see we have here, and will read the history of the case later. Note that the peritoneum is slate-colored, as it always is with blood under it, and that on opening it a quantity of bloody serum runs out. Now that I retract the edges of the incision, note the color of the tumor, which presents slate in some places and deep cherry in others. I have now tapped the cyst and, as you see, the contents are bloody. I gradually deliver the cyst as it is emptied, and you note the numerous but easily separated adhesions. Through these adhesions these cysts are sometimes nourished after the pedicle has been completely divided by twisting. Now I deliver the tumor and show you here the twist in the pedicle which accounts for the blood in the tumor, as well as for that in the peritoneal cavity.
