　We report a case of treatment of active bleeding from endometriotic lesion around the broad ligament of the uterus that occurred during hysteroscopic surgery. A 35-year-old woman, gravida 0, was diagnosed with submucosal myoma. Although she had also suffered from left 5 cm dia. ovarian endometriotic cyst, which had been shrunk by low-dose estrogen and progestin, only hysteroscopic myomectomy was performed. Surgical procedure performed was as follows: 1. Hysteroscopic myomectomy was performed, during which the fundus of uterus was inadvertently perforated. 2. A large amount of intraperitoneal bleeding was observed under laparoscopy. 3. We immediately repaired the perforation site; however, the intraperitoneal bleeding was not stopped. 4. Careful observation revealed active bleeding from the endometriotic lesion around the broad ligament of uterus, while no endometrioma was found in the area. 5. Bleeding was stopped by clipping the bleeding point with Vascular Clip (PL594R) and suturing the same point. The patient progressed favorably after the surgery without any complications such as massive rebleeding. Three months after the operation, she started to attempt to conceive. Active bleeding from endometriotic lesion around the broad ligament of uterus during hysteroscopic surgery is a rare complication. However, attention should be paid to it when the patient has a history of endometriosis.
