Abstract
ObjectiveTo evaluate 2 different predicting scores of submucous myoma removal, fluid balance, and operative time in woman undergoing hysteroscopic myomectomy. DesignA multicenter and prospective study (Canadian Task Force classification II-2). SettingSix hysteroscopy centers in Brazil. PatientsA total of 191 women who underwent hysteroscopic resection of 205 submucous myomas. InterventionResection of submucous myomas (hysteroscopic myomectomy). Myomas were scored according to the European Society for Gynaecological Endoscopy (ESGE) and STEPW (size, topography, extension, penetration, and wall) classifications. The validation of the 2 classifications was assessed with sensitivity and specificity of each classification, with their best cutoff point. Main Outcome MeasuresTo correlate ESGE and STEPW classifications with complete or incomplete removal of submucous myoma, length of surgery, surgical complications, and fluid balance. ResultsRemoval of the myoma was complete in 190 (92.7%) of 205 myomectomies, and incomplete in 15 (7.3%). All 140 (100%) of 140 myomas with a score ≤4 in the STEPW classification were completely removed, and 50 (76.9%) of 65 myomas with a score >4 were removed. All 15 (100%) cases of incomplete hysteroscopic myomectomy had a STEPW score >4. With the ESGE classification, 156/164 (95.1%) cases of type 0 and type 1 myomas, and 34/41 (82.9%) of type 2 were completely resected. STEPW scores >4 were statistically associated with longer duration of surgery, surgical complications, higher levels of fluid balance, and use of gonadotropin releasing hormone analogue if compared with lower scores. The ESGE scores were not associated with any of these variables. ConclusionClassifying submucous myomas with the STEPW classification allows better prediction of myoma removal, fluid balance, length of surgery and surgical complications in hysteroscopic myomectomy than ESGE classification.
