Risk factors for intraoperative hemorrhage during cesarean myomectomy

Management of Uterine Fibroids and Sarcomas: The Palermo Position Paper

BACKGROUND

Uterine fibroids are benign monoclonal tumors originating from the smooth muscle cells of the myometrium, constituting the most prevalent pathology within the female genital tract. Uterine sarcomas, although rare, still represent a diagnostic challenge and should be managed in centers with adequate expertise in gynecological oncology.

OBJECTIVES

This article is aimed to summarize and discuss cutting-edge elements about the diagnosis and management of uterine fibroids and sarcomas.

METHODS

This paper is a report of the lectures presented in an expert meeting about uterine fibroids and sarcomas held in Palermo in February 2023.

OUTCOME

Overall, the combination of novel molecular pathways may help combine biomarkers and expert ultrasound for the differential diagnosis of uterine fibroids and sarcomas. On the one hand, molecular and cellular maps of uterine fibroids and matched myometrium may enhance our understanding of tumor development compared to histologic analysis and whole tissue transcriptomics, and support the development of minimally invasive treatment strategies; on the other hand, ultrasound imaging allows in most of the cases a proper mapping the fibroids and to differentiate between benign and malignant lesions, which need appropriate management.

CONCLUSIONS AND OUTLOOK

The choice of uterine fibroid management, including pharmacological approaches, surgical treatment, or other strategies, such as high-intensity focused ultrasound (HIFU), should be carefully considered, taking into account the characteristics of the patient and reproductive prognosis.

Outcomes of cesarean myomectomy via trans-endometrial approach in women with single intramural fibroid in the posterior uterine wall

OBJECTIVE

To evaluate the feasibility and effectiveness of cesarean myomectomy (CM) via trans-endometrial approach in pregnant women with single intramural fibroid in the posterior uterine wall.

METHODS

Ninety-eight patients with single intramural fibroids in the posterior uterine wall who underwent CM were divided into two groups depending on surgical style. The study group consisted of 50 patients who underwent trans-endometrial myomectomy (EM), whereas the control group included 48 patients who had trans-serosal myomectomy (SM). Patients' demographic data, intraoperative and postoperative outcomes were analyzed retrospectively.

RESULTS

No significant differences were found in the baseline characteristics of the two groups, including demographic data, size, location of fibroids, comorbidities, and indications for cesarean section. During the perioperative period, we did not observe significant differences between the two groups in terms of intraoperative hemorrhage, blood transfusion rate, postoperative fever incidence and postoperative hospitalization (all p > .05). It's worth noting that the time of operation and postoperative ventilation in the EM group was shorter than that in the SM group (p < .05). More importantly, estimated blood loss and postoperative hemoglobin decline were less in the EM group than in the SM group (p < .05).

CONCLUSION

EM seems to be a viable approach to CM for the treatment of single intramural fibroids in the posterior wall, with the potential advantages of short operative time, low intraoperative bleeding, and low risk of pelvic adhesions.

Risk factors for intraoperative hemorrhage of Type I neurofibromatosis

INTRODUCTION

Neurofibromatosis (NF) is an inherited disease and a benign tumor originating from nerve sheath cells. Neurofibromatosis type I (NF1) is the most common type, and most cases are characterized by neurofibromas. Neurofibromas in NF1 are mainly treated by surgery. Our study explores the risk factors for intraoperative hemorrhage in Type I neurofibromatosis patients who underwent neurofibroma resection.

METHODS

A cross-sectional comparison of the patients who had undergone resection of neurofibroma for NF1. Data regarding patient characteristics and data about operative outcomes were recorded. The definition of intraoperative hemorrhage group was the intraoperative blood loss greater than 200 ml.

RESULTS

Of 94 eligible patients, 44 patients were in the hemorrhage group and 50 patients were in the non-hemorrhage group. Multiple logistic regression analysis demonstrated that the area of excision, classification, surgical site, primary surgical, and organ deformation were significant independent predictors of hemorrhage.

CONCLUSION

Early treatment can reduce the tumor cross-sectional area, avoid organ deformation, and reduce intraoperative blood loss. For plexiform neurofibroma or neurofibroma of the head and face, the amount of blood loss should be predicted correctly, and preoperative evaluation and blood preparation should be paid more attention to.

Clinical outcome analysis of intramural myoma greater than 8 cm in diameter removed during caesarean section: a retrospective study

OBJECTIVE

To explore the safety and efficiency of endometrial myomectomy (EM) and Serosal myomectomy (SM) for the removal of intramural myoma greater than 8 cm in diameter during cesarean section.

METHODS

Retrospective analysis and follow-up were used, and 190 cases of pregnancy complicated with uterine myoma from Jan. 2017 to May 2022 in Ningbo Women's and Children's Hospital were collected, 130 cases of caesarean myomectomy as study group, 64 cases of EM as study group A, 66 cases of SM as study group B, 33 cases with uterine fibroids removed before suturing the uterine incision as study group B1, 33 cases with uterine incision sutured followed by removal of fibroids as study group B2, 60 cases of Caesarean section alone as control group. To compare perioperative conditions between and within groups.

RESULTS

① Operation time, postoperative exhaust time, pre- and post-operative haemoglobin drop, intraoperative blood loss were all more than those of the control group in the study group (68.65 ± 11.87 vs 56.17 ± 9.18 min, 21.04 ± 4.98 vs 17.03 ± 1.3 h, 1.27 ± 0.59 vs 1.09 ± 0.43 g/dl, 613 ± 221 vs 532 ± 156 ml, P < 0.001, P < 0.001, P = 0.025, P = 0.011). ② For type III and V fibroids, the time of myoma removal, postoperative exhaust and pre- and post-operative haemoglobin drop and intraoperative blood loss in study group A were less than those in study group B (18.02 ± 3.89 vs 20.19 ± 5.32 min, 18.83 ± 2.57 vs 23.93 ± 6.84 h, 600 ± 194 vs 730 ± 277 ml, 1.20 ± 0.57 vs 1.59 ± 0.70 g/dl, P = 0.036, P < 0.001, P = 0.014, P = 0.008); For type IV uterine fibroids, only postoperative exhaust time was less in Study Group A than in Study Group B (19.27 ± 2.2 vs 21.35 ± 3.23 h, P = 0.016). ③ Time of myoma removed was less in study group B1 than in study group B2 (18.24 ± 4.53 vs 20.7 ± 4.59 min, P = 0.033).

CONCLUSION

It is safe and feasible to remove interstitial myomas larger than 8 cm in diameter during caesarean section. EM has the advantage of shorter operation time and less intraoperative bleeding, SM, in a way that the myoma is removed before suturing the uterine incision, can shorten the myomectomy time. It can benefit the patients more.

The role of minimally invasive gynecologic surgeons in the era of subspecialties: when to refer and consult

PURPOSE OF REVIEW

Minimally invasive gynecologic surgery (MIGS) is a subspecialty focus of obstetrics and gynecology with focused expertise on complex benign gynecologic disorders. To date, no formal recommendations have been made in defining a referral system for MIGS. This article reviews the evidence regarding common disorders and procedures and their outcomes, and posits a basis for MIGS referral.

RECENT FINDINGS

In instances where intraoperative and perioperative features may pose clinical challenges to the surgeon and ultimately the patient, the literature suggests the following scenarios may have adverse outcomes, and therefore, benefit from the skills of MIGS subspecialists: fibroids - at least five myomas, myoma size at least 9 cm, and suspected myoma weight at least 500 g; endometriosis - presence of endometrioma(s), suspected stage III/IV endometriosis, and requirement for advanced adjunct procedures; hysterectomy - uteri at least 250 g or 12 weeks estimated size, at least three prior laparotomies, obesity, and complex surgical history with suspected adhesive disease.

SUMMARY

A referral system for MIGS subspecialists has proven benefits for both the gynecologic surgical community as well as the patients and their outcomes. This article provides evidence for collaboration with MIGS especially as it relates to leiomyomatous uteri, endometriosis, and complex hysterectomies.

The trend in cesarean myomectomies and the risk of obstetrical complications in Korea

BACKGROUND

To evaluate pregnancy outcomes and the risk of adverse obstetrical outcomes of cesarean myomectomy (CM) compared with cesarean section (CS) only, and to investigate the trend of surgeons in choosing CM.

METHODS

A retrospective cohort study was performed on all patients who underwent CS complicated by leiomyoma at two university hospitals between January 2010 and May 2020. All patients were categorized into the CM (341 women) or CS-only (438 women) group. We analyzed the demographic factors, obstetric factors, surgical outcomes, and possible risk factors for adverse outcomes between the two groups.

RESULTS

Women who underwent CS only were significantly more likely to have a previous myomectomy and multiple leiomyoma history than women who underwent CM. The gestational age at delivery and pregnancy complications were significantly higher in the CS-only group. The mean size of the leiomyomas was larger in the CM group than in the CS-only group (5.8 ± 3.2 cm vs. 5.2 ± 3.1 cm, P = 0.005). The operation time and history of previous CS and preterm labor were higher in the CM group. The leiomyoma types differed between the two groups. The subserosal type was the most common in the CM group (48.7%), and the intramural type was the most common in the CS-only group. Patients in the CM group had fewer than three leiomyomas than those in the CS-only group. Preterm labor and abnormal presentation were relatively higher in the CM group than in the CS-only group, concerning leiomyoma presence. There were no significant differences in the preoperative and postoperative hemoglobin levels. The size of the leiomyoma (odds ratio [OR] = 1.162; 95% confidence interval [CI]: 1.07-1.25; P < 0.001) and operation time > 60 min (OR = 2.461; 95% CI: 1.45-4.15) were significant independent predictors of adverse outcomes after CM.

CONCLUSIONS

CM should be considered a reliable and safe approach to prevent the need for another surgery for remnant leiomyoma. Herein, surgeons performed CM when uterine leiomyomas were large, of the subserosal type, or few. Standardized treatment guidelines for myomectomy during CSs in pregnant women with uterine fibroids should be established.
