Longer Operative Time During Laparoscopic Myomectomy Is Associated with Increased 30-Day Complications and Blood Transfusion

Factors influencing intraoperative blood loss and hemoglobin drop during laparoscopic myomectomy: a tailored approach is possible?

A retrospective study was conducted on patients subjected to laparoscopic myomectomy at our institution from January 2017 to December 2018 to identify predictive factors of blood loss. Two multiple regression models were run to predict intraoperative blood loss and haemoglobin drop. Predictors of an increased intraoperative blood loss and haemoglobin drop were the presence of three-four fibroids at ultrasound (+47 ml, p = .01; +0.58 g/dl, p = .05) and increased operative time (r = 0.57, p = .01; r = 0.01, p < .01), while predictors of a reduced intraoperative blood loss and haemoglobin drop were epinephrine injection (-50 ml, p < .01; -0.42 g/dl, p < .01), FIGO7 (-87 ml, p < .01; -0.85, p = .01), and FIGO6 (-35 ml, p < .01; -0.44, p = .02) fibroids at the ultrasound. Preoperative ultrasound evaluation is crucial in identifying patients at higher risk for blood loss, which could benefit from optimising haemoglobin values. The injection of diluted epinephrine could be proposed in selected high-risk patients. In the clinical practice, a tailored approach based on fibroids' ultrasonographic characteristics should be implemented to optimise preoperative Hb values and evaluate the use of diluted epinephrine in selected cases, reducing blood loss and the potential related complications.Impact statementWhat is already known on this subject? Laparoscopic myomectomy is the conservative surgical treatment of choice for symptomatic uterine fibroids. Still, it could represent a challenging procedure even for an experienced surgeon, with the risk of excessive blood loss, need of transfusions, prolonged operative time, and prolonged hospital stay. The knowledge of the predictive factors of blood loss is essential for patient preparation and surgical planning to reduce intraoperative and postoperative complications.What do the results of this study add? The results of the present study focus on the importance of presurgical evaluation to identify predictive factors of intraoperative blood loss and Hb drop such as the number of fibroids and the FIGO classification (at preoperative ultrasound), as well as intraoperative factors like operative time and the intramyometrial injection of diluted epinephrine.What are the implications of these findings for clinical practice and/or further research? A tailored approach based on the ultrasonographic characteristics of fibroids should be implemented to optimise preoperative haemoblobin levels.

The Significant Risk Factors of Intra-Operative Hemorrhage during Laparoscopic Myomectomy: A Systematic Review

Laparoscopic myomectomy (LM) is becoming increasingly common in the management of uterine myomas and is usually offered regardless of the number, location, and size of the myomas. It has a generally low rate of periprocedural complications and is preferred to laparotomy for several reasons that are not limited to decreased length of hospital stay, number of sutures, smaller incisions, and decreased pain. However, blood loss during LM remains a challenge. To be able to stratify patients and provide better management after LM, it is crucial to identify these predictors of blood loss. Therefore, the aim of this review was to identify the risk factors for periprocedural blood loss after laparoscopic uterine myomectomy. According to our data synthesis, age, body mass index, and phase of the menstrual cycle do not seem to affect the blood loss during LM. Conversely, size and number of myomas, as well as operative time, was directly related to the increase of blood loss.

Characteristics Associated with Prolonged Length of Stay after Myomectomy for Uterine Myomas

STUDY OBJECTIVE

To identify factors contributing to prolonged hospitalization for women undergoing myomectomy for uterine myomas.

PATIENTS

Women undergoing myomectomy for uterine myomas during 2014 to 2016 were identified by the Current Procedural Terminology code.

DESIGN

Retrospective population-based analysis of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database.

SETTING

Data from the American College of Surgeons National Surgical Quality Improvement Project.

INTERVENTIONS

None.

MEASUREMENTS AND MAIN RESULTS

The primary outcome was length of stay longer than the median (1 day). Preoperative, intraoperative, and postoperative variables were examined to determine predictors for prolonged length of stay (LOS). Seven thousand five hundred thirty-one women underwent abdominal or laparoscopic myomectomy for uterine myomas. Nonwhite race (black: odds ratio [OR] = 2.25; 95% confidence interval [CI], 2.01-2.51; Asian: OR = 1.54; 95% CI, 1.27-1.85; other/unknown: OR = 2.82; 95% CI, 2.43-3.27), preoperative hematocrit <38% (OR = 1.38; 95% CI, 1.26-1.52), body mass index ≥30.1 kg/m² (OR = 1.36; 95% CI, 1.21-1.53), preoperative blood transfusion (OR = 3.70; 95% CI, 2.03-6.74), perioperative blood transfusion (OR = 6.64; 95% CI, 4.76-9.27), removal of ≥5 myomas (OR = 1.47; 95% CI, 1.28-1.70), and operative time >120 minutes (121-150 minutes: OR = 1.42; 95% CI, 1.15-1.77; 151-180 minutes: OR = 1.59; 95% CI, 1.24-2.03; ≥181 minutes: OR = 1.36; 95% CI, 1.10-1.69) predicted prolonged LOS. Laparoscopy protected against prolonged LOS (OR = 0.11; 95% CI, 0.09-0.13).

CONCLUSIONS

Limited potentially modifiable perioperative factors contributing to prolonged LOS for abdominal or laparoscopic myomectomy were identified and suggest areas for targeted interventions.
