Three cases of giant ovarian tumors exceeding 30 cm in length experienced at our hospital

We report three cases of giant ovarian tumors. In all cases, we initially performed slow aspiration of the tumor content through a small abdominal incision made under local anesthesia, and general anesthesia was administered after confirmation of circulatory stability. Case one was a 52-year-old woman who presented with abdominal fullness and generalized weakness, and was intubated. Following aspiration of 20 L of ovarian tumor content, right salpingo-oophorectomy was performed. Postoperatively, she was extubated, but was unable to expectorate; thus, tracheostomy was performed. She developed disuse syndrome. Case two was a 44-year-old woman with right ovarian tumor. After aspiration of 20 L of tumor content, radical surgery was performed without complications. Case three was an 86-year-old woman who presented with abdominal fullness and anorexia, and was diagnosed with pneumonia, right ovarian tumor, and deep vein thrombosis. After inferior vena cava filter was inserted, 10 L of tumor content was aspirated, and bilateral salpingo-oophorectomy was performed. This study reiterates the importance of careful perioperative management for giant ovarian tumors. These cases require preoperative evaluation for deep vein thrombosis, circulatory monitoring during surgery, and management of reexpansion pulmonary edema and disuse syndrome in the postoperative period. 〔Adv Obstet Gynecol, 76(1): 45-53, 2024(R6.2)〕
