BACKGROUNDThe procedure for microwave endometrial ablation (MEA) follows established MEA practice guidelines but requires hysteroscopic observation of the uterine lumen before and after MEA. When a luminal uterine lesion is recognized, its removal requires preoperative dilation of the cervix because the outer diameter of a conventional rigid hysteroscope is 8.7 mm. Recently, a fully disposable rigid hysteroscope (LiNA OperaScopeTM) with a narrow diameter (4.4 mm) and forceps capable of extracting endometrial lesions has become available.CASE SUMMARYHere, we report a case of heavy menstrual bleeding (HMB) complicated by endometrial polyps where MEA was performed after removing endometrial polyps using the LiNA OperaScopeTM device. A 48-year-old woman with three prior pregnancies and three deliveries was referred to our hospital for further examination and treatment after being diagnosed with HMB 2 years earlier. The patient underwent MEA following endometrial polypectomy using LiNA OperaScopeTM. After MEA, endometrial cauterization was again examined using the LiNA OperaScopeTM, and the procedure was completed. No preoperative cervical dilation was performed. The patient's clinical course was favorable, and she was discharged 3 h after surgery. One month after surgery, menstruation resumed, and both HMB and dysmenorrhea improved markedly from 10 preoperatively to 1 postoperatively, as assessed subjectively using the visual analog scale. The patient's postoperative course was uneventful with no complications.CONCLUSIONLiNA OperaScopeTM can be a minimally invasive treatment for MEA of HMB with uterine lumen lesions.
