%X <B>OBJECTIVE: </B>To evaluate the use of dilute carboprost tromethamine injection at the endometrium/myoma junction during hysteroscopy to facilitate myoma expulsion and removal in a single procedure.<BR><B>METHODS: </B>Case series.<BR><B>METHODS: </B>Single high-volume academic medical center.<BR><B>METHODS: </B>Seven patients aged 32 to 51 years old with FIGO type 2 uterine myomas and symptoms of abnormal uterine bleeding or infertility undergoing hysteroscopic resection with a morcellation device from November 2022 to July 2023.<BR><B>METHODS: </B>Dilute injection of carboprost tromethamine (10 µg/mL) at time of hysteroscopic myomectomy.<BR><B>RESULTS: </B>The main outcome measure was ability to complete the hysteroscopic myomectomy in a single procedure using a hysteroscopic morcellator. Secondary outcomes included total operative time, fluid deficit, and postoperative pharmacologic side effects and/or surgical complications. Among our 7 patients, all had successful single procedure complete resections of myomas ranging from 0.9 to 4.6 cm in maximal diameter. Average operative time was 30 minutes, and average fluid deficit was approximately 839 mL. The carboprost dosages used ranged from 30 to 180 µg. One patient experienced prolonged postoperative nausea and vomiting that resolved with antiemetics. One patient experienced postoperative endometritis that improved with antibiotics.<BR><B>CONCLUSIONS: </B>In this pilot study, injection of dilute carboprost intraoperatively facilitated one-step hysteroscopic myomectomy of FIGO 2 myomas, via enhanced extrusion of the intramural portion of the fibroid into the uterine cavity, with both short operative times and acceptable fluid deficits.
