Myomectomy during caesarean: a retrospective evaluation of 16 cases

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.

World Federation for Ultrasound in Medicine Review Paper: Incidental Findings during Obstetrical Ultrasound

Although the prevalence of incidental findings revealed during an obstetric ultrasound examination is low, the findings may include adnexal and cervical masses, uterine or urinary congenital malformations, free fluid in the pouch of Douglas or tortuous vessels (varices). Adnexal masses are the most common finding and vary in imaging characteristics. They are mainly unilateral, cystic masses with a low risk of malignancy that are treated conservatively. The International Ovarian Tumor Analysis scoring models may be helpful in differentiating benign from malignant masses. For those masses >5 cm, follow-up is recommended, and resection could be considered to avoid risk of torsion, rupture and hemorrhage, which may compromise pregnancy outcome. Uterine masses such as fibroids are commonly diagnosed early in the first trimester and should be followed up during pregnancy to evaluate any changes. Transabdominal and transvaginal ultrasound is the first-line test for the diagnosis of such incidentalomas; however, magnetic resonance ultrasound may have a useful role in excluding malignancy potential. As a result of their low frequency and the lack of good evidence, there are no specific guidelines on the management of incidentalomas detected at obstetric scans. Their management should follow the related general guidelines for ovarian, cervical and uterine masses, with individualized management depending on the pregnancy status.

Study on the method of enucleation of anterior uterine fibroids by transverse incision of the lower uterine segment during cesarean section

Introduction

A retrospective study was conducted to investigate the effectiveness and feasibility of fibroid enucleation in the anterior wall of the uterus by transverse uterine incision during cesarean section.

Methods

The medical history, surgical data, preoperative and postoperative changes in the blood system, and complications of 90 pregnant women who underwent myomectomy of the anterior uterine wall during cesarean section at the second Department of Maternal and Child Health Hospital of Fujian Province were analyzed retrospectively.

Results

No significant differences were noted in the leiomyoma number, pathological type, preoperative and postoperative hemoglobin level, perioperative bleeding incidence, blood transfusion frequency, postoperative fever incidence, and duration of lochia between the study and control groups. The proportion of large fibroids was slightly higher in the study group than in the control group (p < 0.05), and the operation time and average hospitalization time were slightly longer in the study group than in the control group (p < 0.05). The distribution of type III–V fibroids was slightly more in the study group than in the control group (p < 0.05), and the distribution of type VI fibroids in the study group was less than that in the control group (p < 0.05).

Conclusion

Fibroid enucleation is safe and effective in the anterior wall of the uterus through the lower uterine transverse incision in cesarean section. It has the potential to reduce the risk of pelvic and intrauterine adhesions in the future.

Risk factors for intraoperative hemorrhage during cesarean myomectomy

OBJECTIVE

We intended to identify the risk factors of intraoperative hemorrhage on occasions of a combined operation of myomectomy with cesarean section for patients with uterine leiomyoma.

MATERIALS AND METHODS

A retrospective cohort study was done of all patients who underwent cesarean myomectomy for intramural leiomyoma at a single university hospital. Cases identified with subserosal leiomyoma, placental disorder, and comorbid conditions related to coagulopathy were excluded. All the included cases were classified into intraoperative hemorrhage and non-hemorrhage group. Obstetric and demographic factors and parameters of leiomyoma were compared between two groups.

RESULTS

A total of 302 women underwent cesarean myomectomy during the study period. Among these women, 212 pregnant women met the inclusion criteria. Intraoperative hemorrhage occurred in 43 women (20.3%). There was no significant intergroup difference in the number of removed leiomyomas. Multiple logistic regression analysis demonstrated that lower segmental location (odds ratio [OR], 2.827; 95% confidence interval [CI], 1.033-7.734, P = 0.043) and the diameter (OR, 1.167; 95% CI, 1.044-1.305, P = 0.006) were significant independent risk factors for hemorrhage during cesarean myomectomy. The combination of ≥ 8 cm diameter or lower segmental position of the leiomyoma yielded a specificity of 79.3% for operative hemorrhage during cesarean myomectomy. The negative predictive value of this combination was 88.7% for operative hemorrhage with a prevalence of 20%.

CONCLUSION

The large size and lower segmental position of the leiomyoma are significantly risk factors for intraoperative hemorrhage during cesarean myomectomy. If the leiomyoma is located in the uterine fundus or body and its diameter is less than 8 cm, the removal of leiomyoma may be considered at the time of cesarean section.

Analysis of Myomectomy during Cesarean Section: A Tertiary Center Experience

PURPOSE

This study analyzed the safety of myomectomy during the cesarean section (CS).

METHODS

Pregnant women who underwent myomectomy during CS in a tertiary center between January 2015 and November 2019 were included in the study in Group A, and pregnant women who did not have myoma and who underwent only CS were included in the study in Group B. The following information was obtained from patient files in hospital archives and was then recorded and compared: age, gravidity, parity, gestational week, characteristics of the myomas (i.e., location, size, number, and type), duration of surgery, perioperative complications, need for blood transfusion, preoperative and postoperative hemoglobin (Hb) values, duration of surgery, and hospital stay duration.

RESULTS

A total of 83 patients underwent CS plus myomectomy (Group A), and 80 patients (without myoma) underwent only CS (Group B).There were no statistically significant differences between the groups in terms of preoperative and postoperative Hb values or blood transfusion rates (p > 0.05). Hospitalization and surgery duration were significantly higher in the group that underwent CS myomectomy (p = 0.001 and p = 0.001, respectively). The mean myoma size was 8.3 ± 4.1 cm in Group A. There was a statistically significant and inverse correlation between the size of the myoma and the delivery week (p = 0.035). There was a statistically significant and positive correlation between the myoma size and hospital stay (p = 0.01).

CONCLUSION

Myomectomy during CS is safe and can be applied regardless of the location, size, type, and number of myomas. However, to make myomectomy routine during CS, multi-center studies that include more cases are needed.

Myomectomy During Cesarean Section: Why Do We Abstain From?

Objectives

To assess the intra- and postoperative results of cesarean myomectomy.

Methods

A retrospective study was conducted to collect the results of cesarean myomectomy procedures performed in our tertiary center between June 2013 and December 2018. The subjects were 2219 pregnant women undergoing cesarean section at these units.

Results

A total of 2219 scheduled patients undergoing CS were included in the present study. Sixty-five patients have undergone intramural myomectomy during CS; 82 patients have had subserosal myomectomy during CS. No statistically significant differences were found between the three groups in changes of preoperative Hb, postoperative Hb, mean Hb and length of hospital stay. Operation times were significantly longer in both intramural and subserosal myomectomy groups (45.23 ± 8.498 vs. 39.02 ± 6.824 vs. 32.14 ± 5.423 min, p 0.01). Only in the intramural myomectomy group, two patients were subjected to blood transfusion (3%). Assessment of intramural myomectomy patients was carried out by taking 5 cm as the cutoff value. No statistical differences were found between the two groups in terms of mean Hb change, operation time, length of hospital stay. In the group with intramural myomectomy larger than 5 cm, two (15.38%) patients needed a blood transfusion.

Conclusions

Cesarean myomectomy operation performed by experienced surgeons has no adverse effects other than lengthening the duration of operation and can be safely implemented.

Use of the base purse-string suture approach to remove giant uterine fibroids during cesarean section

Objective

This study aimed to investigate the optimal strategy for myomectomy for removing giant uterine fibroids when necessary in women undergoing cesarean section.

Methods

This study was retrospective in design, and assessed outcomes in 26 patients who underwent myomectomy using a “base purse-string suture” during cesarean section. The operative duration, blood loss, uterine involution, and duration of postpartum lochia were analyzed.

Results

This suture was associated with a mean operative duration of 11.17 ± 5.36 minutes and the mean estimated blood loss was 11.15 ± 6.05 mL. The mean postpartum duration of lochia was 34.92 ± 7.55 days and there were no cases of postpartum hemorrhage. Uterine size returned to normal within 6 weeks of delivery, without any apparent defects or abnormalities in the uterine wall as shown by an ultrasonic examination.

Conclusion

This novel implementation of a base purse-string suture during cesarean myomectomy for removal of giant fibroids is a simple, safe, and effective intervention that should be considered for implementation in appropriate patients.

Cesarean Myomectomy: An Experience from a Tertiary Care Teaching Hospital

Background

Recent literature supports the removal of myomas during cesarean section, which traditionally was considered a relative contraindication, given a higher complication rate. This study is to share our experience of cesarean myomectomy in the last decade.

Methods

This study is a retrospective review of our prospectively maintained database, from January 2008 to December 2017, at a tertiary care level teaching institution. All patients who underwent myomectomy during cesarean section were included. There were no exclusions.

Results

A total of twenty patients underwent myoma removal along with the cesarean operation during this period with a mean age of 30 years. Majority of patients were nulliparous (70%). Common comorbidities were diabetes mellitus (40%) and hypothyroidism (20%). Mean size of myomas were 5.33 cm (± 2.08), and the number varied from one to three. The most common location was the posterior surface of the uterus with the commonest variety being subserous. Most patients were discharged on the fifth postoperative day.

Conclusion

This study demonstrates that cesarean myomectomy to be a safe and feasible procedure in experienced hands. It offers the advantage of avoiding a second surgery in selected patients.

Management of uterine fibroids in pregnancy: recent trends

PURPOSE OF REVIEW

The review analyzes how fibroids may influence pregnancy and how myomas may be modified by pregnancy. The most important clinical aspect concerns the impact of myoma on pregnancy and the possibility of a well tolerated surgical treatment for the mother and her fetus, preserving maternal reproductive capacity.

RECENT FINDINGS

Fibroids significantly increase in size during early pregnancy and then decrease in the third trimester. Although most women with uterine fibroids have a regular pregnancy, data from the literature suggest that they may have a higher risk of fertility problems and pregnancy complications.

SUMMARY

Myomectomy can increase the rate of pregnancy in women with infertility, attempting to restore a normal anatomy and reduce uterine contractility and local inflammation associated with the presence of fibroids, improving the blood supply. Current evidence does not suggest routine myomectomy during pregnancy or at the cesarean birth, as fibroids-related complications are rare and may be overcome by the risks of surgery. However, in selected cases, myomectomy is a feasible and safe technique and associated to a good outcome.The diagnosis of myomas in pregnancy may require attention for the adequate management to preserve maternal and fetal well-being.

Cesarean myomectomy trends and controversies: an appraisal

OBJECTIVE

Although the first report on cesarean myomectomy (CM) was a century ago, the management of a myomectomy during a cesarean section (CS) remains controversial. The objective of this study is to provide the latest data on this topic regarding the techniques and complications of CM.

METHODS

The authors consulted the most important scientific databases investigating the indications and contraindications for CM, the operational techniques, benefits and complications.

RESULTS

CM provides the benefits of two surgeries in one laparotomy, avoiding the risks of repeated anesthesia and relaparotomy. Nevertheless, in some patients, CM may be associated with increased morbidity and, in such cases, an interval myomectomy might be a safer option. Myomas compromising fetal extraction and uterine incision and/or suturing should be preferably enucleated during CS. CM is generally considered relatively safe in cases of anterior wall myomas, subserous and pedunculated myomas, particularly if a myomectomy is feasible without additional hysterotomy. Multiple myomas, deep intramural, fundal and cornual myomas and posterior uterine wall myomas are associated with more surgical complications during CM.

CONCLUSIONS

With increasing reports in favor of CM, the risk-benefit ratio should be still evaluated with randomized controlled trials, in order to achieve more data on CM.
