Uterine Isthmus Tourniquet during Abdominal Myomectomy: Support or Hazard? A Randomized Double-Blind Trial

The Hangman's Tourniquet: A Safe and Practical Approach for Reducing Blood Loss During Uterine Myomectomy

STUDY OBJECTIVES

The application of a pericervical uterine artery tourniquet is a useful method of reducing intraoperative haemorrhage during abdominal myomectomy. However, the utilization of a single combined pericervical uterine artery and infundibulopelvic ligament tourniquet is a more effective and influential method of temporarily occluding the uterine vasculature to decrease intraoperative blood loss, reducing the requirement for blood products, the risk of conversion to hysterectomy, and patient morbidity and mortality during fertility-sparing leiomyoma surgery. Our objective of this retrospective review was to assess the effectiveness of the combined uterine artery and infundibulopelvic ligament tourniquet, which we coin as the "Hangman's uterine tourniquet", in reducing intraoperative blood loss during abdominal myomectomy, thereby reducing the need for blood products.

METHODS

This retrospective study included 39 patients diagnosed with symptomatic subserosal, intramural, and/or submucosal uterine leiomyoma (>3 cm) who underwent an abdominal myomectomy between January 2021 and December 2022.

RESULTS

Thirty-nine patients met the eligibility criteria for our study. The average patient age included in our study was 36 years. All myomectomies were completed with a mean intraoperative blood loss of 252.60 ml and the average number of fibroids removed was seven. The largest fibroid removed measured 27 x 20 cm in diameter while the most significant number of fibroids removed was 41. Moreover, the mean duration of the tourniquet application was 45.31 minutes, and the mean duration of operation was 80.44 minutes. Thirty-six patients (92.3%) had an estimated blood loss <500 ml. The number of fibroids removed was a statistically significant risk factor influencing estimated blood loss (p = 0.019). However, there was no statistical significance between estimated blood loss and the size of the largest fibroid removed (p = 0.178) nor estimated blood loss and a history of previous surgery (p = 0.412). The postoperative blood transfusion rate was 2.5% and no patients suffered grade III or higher surgical complications according to the Clavien-Dindo classification.

CONCLUSION

This study showed that the utilization of a temporary intraoperative combined pericervical uterine artery and infundibulopelvic ligament tourniquet is an effective, practical, and economical approach to limiting intraoperative blood loss during abdominal myomectomy.

The Efficiency of a Uterine Isthmus Tourniquet in Minimizing Blood Loss during a Myomectomy-A Prospective Study

Background and Objectives: The objective of this study was to assess the effectiveness of using a peri-cervical tourniquet in reducing blood loss during a laparoscopic myomectomy. Materials and Methods: This prospective study evaluated the impact of performing a concomitant tourniquet placement during a laparoscopic myomectomy (LM). A total of 60 patients were randomly allocated to one of two groups: 30 patients who underwent an LM with a tourniquet placement (the TLM group) and 30 patients who benefited from a standard LM (the SLM group). This study's main objective was to evaluate the impact of tourniquet use on perioperative blood loss, which is quantified as the difference in the pre- and postoperative hemoglobin levels (Delta Hb) and the postoperative blood transfusion rate. Results: The mean Delta Hb was statistically lower in the TLM group compared to the SLM group: 1.38 g/dL vs. 2.41 g/dL (p < 0.001). The rate of postoperative iron perfusion in the TLM group was significantly lower compared to the SLM group (4 vs. 13 patients; p = 0.02). All four patients that required a blood transfusion were from the SLM group. On average, the peri-cervical tourniquet fastening time was 10.62 min (between 7 and 15 min), with no significant impact on the overall operative time: 98.50 min for the TLM group compared to 94.66 min for the SLM group. Conclusions: Fastening a tourniquet during a laparoscopic myomectomy is a valuable technique to effectively control intraoperative bleeding and enhance surgical outcomes.

Can the application of a temporary uterine tourniquet during an abdominal myomectomy reduce bleeding?

Objective

Uterine fibroids are common, benign uterine tumours. The three most common surgical treatment approaches for uterine fibroids are laparoscopic, robotic and abdominal myomectomies. Bleeding is a risk with all three approaches. The present study compared post-operative and pregnancy outcomes in patients with bilateral uterine artery occlusion who underwent an abdominal myomectomy, with or without a temporary uterine tourniquet.

Material and Methods

This retrospective study included patients with intra-mural fibroids (≥5 cm) who underwent an abdominal myomectomy. The patients were divided into two groups according to the use or non-use of a temporary uterine tourniquet. Post-operative and pregnancy outcomes in the tourniquet use and non-use groups were compared. The association of the number of uterine fibroids removed (≤3 vs >3) with laboratory parameters was also evaluated.

Results

A total of 84 patients were included, divided into use (n=36) and non-use (n=48) of the temporary tourniquet. There was a statistically significant difference between the groups with >3 myomas removed and with a uterine tourniquet applied and not applied in terms of reduction in hemoglobin and hematocrit, transfusion amounts, operation times and lengths of hospitalization in favour of the uterine tourniquet use group (p=0.019, p=0.023, p=0.012, p=0.044 and p=0.036, respectively). Bilateral uterine arterial occlusion using a temporary uterine tourniquet had no negative effects on pregnancy outcomes.

Conclusion

A temporary uterine tourniquet may be an effective method for reducing the amount of perioperative bleeding in patients with multiple, large-sized myomas located close to vascular structures.
