New risk stratification tool may predict requirement of blood transfusion among women undergoing laparoscopic myomectomy

The key findings of the study were:

• 11,498 women underwent laparoscopic myomectomy during the study period.

• 331 (2.9%) of these women required blood transfusion.

• Preoperative factors associated with transfusion risk included Black or African American and Asian races, Hispanic ethnicity, bleeding disorders, ASA III/IV, and preoperative hematocrit value ≤35.0%.

• Intraoperative factors included specimen weight >250 grams or ≥5 intramural myomas and operation time ≥197 minutes.

• A risk stratification tool was developed based on these factors, allowing calculation of the mean probability of transfusion.

The study identified preoperative and intraoperative risk factors for blood transfusion in women undergoing laparoscopic myomectomy. A risk stratification tool was developed to assess the likelihood of transfusion based on these factors. Further validation studies are warranted to confirm the utility of this tool in clinical practice.
