title: Two novel classification systems for uterine fibroids and subsequent uterine reconstruction after myomectomy.
abstract: OBJECTIVE
  Laparoscopic approaches are the gold standard surgical treatment for intramural and subserous fibroids, whereas submucosal myomas can be treated via hysteroscopy. Removal of intramural myomas often requires a subsequent reconstruction of the uterine wall that ranges from single- to multiple-layer sutures to complex reconstructions. Several classification systems are currently used to characterize uterine fibroids, all of which focus on the assessment of submucosal fibroids during hysteroscopic myomectomy. There are no classification systems for the comprehensive localization of fibroids or for uterine reconstruction after myomectomy. Therefore, the aim of this study was to validate a new scoring system developed by our group to classify uterine leiomyoma as well as a standardized assessment scoring system for uterine reconstruction after surgical myomectomy.
  
  
  METHODS
  To validate the uterine fibroid and uterine reconstruction classification systems, a retrospective review of 136 patients undergoing surgical myomectomy and uterine reconstruction at a single tertiary institution was performed. The age of the patient, duration of surgery, number, size, and location of excised fibroids, number of uterine incisions, level of uterine reconstruction, desire for future pregnancies, pre- and postoperative hemoglobin concentrations, duration of postoperative hospitalization, and operating surgeon were obtained by medical chart review. For each patient, a specific fibroid score and the level of uterine reconstruction were determined according to the classification systems. Correlations between the uterine fibroid and reconstruction scores, as well as between the classification scores and perioperative parameters, were analyzed.
  
  
  RESULTS
  The newly developed classification system for uterine fibroids incorporates the number, location, and size of myomas, as well as the number of uterine incisions required for myomectomy. The uterine reconstruction scoring system comprises four levels of reconstruction, ranging from no reconstruction to advanced reconstruction. Outcomes from 136 patients showed a correlation between uterine fibroid and uterine reconstructive scores. High fibroid scores were correlated with higher levels of reconstruction. Both scoring systems showed associations with the duration of surgery, intraoperative blood loss, and days of hospitalization.
  
  
  CONCLUSIONS
  This study presents the first scoring system for uterine fibroids that incorporates all possible fibroid locations and a standardized assessment of uterine reconstruction. Scoring systems were validated in a large cohort, and a correlation was identified between uterine fibroid and uterine reconstruction scores. In daily clinical practice, this scoring system allows a better planning of surgery, specifically of the estimated duration of surgery, blood loss, and time of hospitalization.
