Laparoscopic excision of uterine adenomyomas

Effectiveness of Laparoscopic Adenomyomectomy on Perinatal Outcomes

Objectives

The objective of this study was to observe the influence of laparoscopic adenomyomectomy on perinatal outcomes.

Materials and Methods

The retrospective cohort study included 43 pregnant cases with adenomyosis who did not undergo laparoscopic surgery before pregnancy (nonsurgery group; 26 cases) and did (surgery group; 17 cases). To evaluate the impact of surgery on perinatal outcomes, nine obstetric complications including preterm delivery, hypertensive disorder of pregnancy, placental malposition, oligohydramnios, gestational diabetes mellitus, uterine rupture, abruptio placentae, and postpartum hemorrhage were selected. One obstetric complication was counted as one point (Maximum 9 points for one person). The obstetrical morbidity was compared by adding up the number of relevant events (0-9) between the two groups. Apgar score, umbilical artery pH (UApH), neonatal intensive care unit (NICU) admission, and neonatal death were also examined.

Results

The surgery group had a significantly lower prevalence of fetal growth restriction compared to the nonsurgery group (nonsurgery vs. surgery; 26.9%, 7/26 vs. 0%, 0/17: P = 0.031). No differences were found in the morbidity of the nine obstetric complications (19.2%, 45/234 vs. 13.7%, 21/153), gestational weeks (mean ± standard deviation, 37.2 ± 2.4 vs. 36.4 ± 3.2), birth weight (2573.6 ± 557.9 vs. 2555.4 ± 680.8 g), Apgar score (1, 5 min; 8.0 ± 0.7 vs. 7.7 ± 1.2, 8.9 ± 0.6 vs. 8.5 ± 1.8), UApH (7.28 ± 0.08 vs. 7.28 ± 0.06), NICU admission (26.9%, 7/26 vs. 41.2%, 7/17), and neonatal death (0%, 0%) between both groups.

Conclusion

Laparoscopic adenomyomectomy may not increase obstetric complications, although attention must be paid to uterine rupture during pregnancy.

Minimally invasive management of juvenile cystic adenomyoma: report of three cases

Background

Juvenile cystic adenomyosis (JCA) represents a rare form of focal adenomyosis in young women.

Objectives

To determine safety and effectiveness of minimally invasive surgery (MIS for JCA).

Materials and Methods

Three patients aged 16-30 years old presented with chronic pelvic pain [2016 - 2019]. Hormonal treatment failed in two cases. Cystic lesions in the myometrium (n=2), and the broad ligament (n=1) was detected on transvaginal 2D ultrasound (TV 2D US) and/or magnetic resonance imaging (MRI). The cyst was separate from the endometrium in all the cases, within the myometrium in two patients and in the right broad ligament in one case. The cystic lesions were confirmed on laparoscopy; and laparoscopic excision of the cysts with adequate repair of the myometrial beds were performed in all cases with fertility preservation. Robotic assistance was chosen in one case in an attempt to avoid injury of the fallopian tube based on the cyst location during a previous laparoscopy. The endometrial cavity was entered in one case.

Main outcome measures

Absence of intraoperative complications and relief of presenting symptoms postoperatively.

Results

Pathology report confirmed the diagnosis of JCA is all cases. There were no intraoperative complications. All three patients reported relief of their symptoms 6 to 8 months after surgery. No recurrence of the JCA was reported using TV 2D US in all cases.

Conclusions

MIS could be the treatment of choice for patients with JCA. The technique described in our study is safe, effective, and easy to master in experienced hands.

What is new?

Value of MIS in treatment of patients with JCA.

Current and Future Surgical and Interventional Management Options for Adenomyosis

Historically, hysterectomy has been the recommended treatment for patients with adenomyosis. However, in the past two decades, various uterine-sparing treatment methods have emerged. These range from excisional techniques such as adenomyomectomy or wedge resection to uterine artery embolization, radiofrequency thermal ablation, hysteroscopic excision, endometrial ablation, and high-intensity focused ultrasound. While largely investigative for the treatment of adenomyosis, these procedures have demonstrated improvement in symptoms including abnormal uterine bleeding, dysmenorrhea, pelvic pain, and overall quality of life. However, long-term data including fertility and obstetric outcomes are needed. Future research is needed to better understand the impact of these uterine-preserving techniques to expand our armamentarium for the treatment of adenomyosis.

Laparoscopic Myomectomy - Converting to Laparotomy for a Suspicious Intraoperative Appearance with Subsequent Benign Histology - a Pre- and Intra-Operative Dilemma

Background

Although the most common uterine tumour is leiomyoma, the differential diagnoses also include the rarer adenomyoma and leiomyosarcoma. A lack of clear reliable clinical and radiological features makes the triage of uterine masses to the appropriate surgical procedure difficult. In the case of suspicious appearance of a presumed leiomyoma, an open surgical approach is recommended and morcellation is avoided.

Case

We present a case of a woman undergoing an elective laparoscopic myomectomy for a fibroid that appeared benign on ultrasound but had suspicious features intraoperatively. The operation was converted to a laparotomy to avoid the risk of morcellation-related seeding in the event that the histology was malignant. The histology was subsequently a benign exophytic adenomyoma.

Conclusion

The assessment of the nature of fibroids can be difficult both pre- and intraoperatively, and the need for difficult decision making to convert to open surgery during a laparoscopic myomectomy but with subsequent benign histology should be part of patient counselling.

A critical review of recent advances in the diagnosis, classification, and management of uterine adenomyosis

PURPOSE OF REVIEW

The purpose of this review is to summarize and highlight recent critical advances in the diagnosis, classification, and management of adenomyosis.

RECENT FINDINGS

Recent studies have clarified the specific mechanism through which adenomyotic lesions invade the underlying myometrium by epithelial-mesenchymal transition. Correlation studies using diagnostic MRI also strongly support the hypothesis of a different pathogenesis between the inner and outer myometrium forms of adenomyosis. Given advances in diagnostic imaging, several international organizations have also highlighted the importance of classification systems for adenomyosis. Finally, selective progesterone receptor modulators and gonadotropin-releasing hormone antagonists have demonstrated significant promise for treating pelvic pain and bleeding associated with adenomyosis, whereas novel fertility-preserving surgical techniques have been introduced to excise diffuse adenomyotic pathology while maintaining adequate uterine integrity.

SUMMARY

Recent attempts at a uniform and reproducible classification system likely represent the first step for the development of a staging system for adenomyosis that can be correlated with the severity of clinical symptoms and promote an individualized therapeutic approach. Simultaneously, further insights into the etiology and pathogenesis as outlined in this review may also help in the development of targeted medical therapies.

Use of Augmented Reality in Gynecologic Surgery to Visualize Adenomyomas

Augmented reality (AR) is a surgical guidance technology that allows key hidden subsurface structures to be visualized by endoscopic imaging. We report here 2 cases of patients with adenomyoma selected for the AR technique. The adenomyomas were localized using AR during laparoscopy. Three-dimensional models of the uterus, uterine cavity, and adenomyoma were constructed before surgery from T2-weighted magnetic resonance imaging, allowing an intraoperative 3-dimensional shape of the uterus to be obtained. These models were automatically aligned and "fused" with the laparoscopic video in real time, giving the uterus a semitransparent appearance and allowing the surgeon in real time to both locate the position of the adenomyoma and uterine cavity and rapidly decide how best to access the adenomyoma. In conclusion, the use of our AR system designed for gynecologic surgery leads to improvements in laparoscopic adenomyomectomy and surgical safety.

Surgery in adenomyosis

INTRODUCTION

Adenomyosis is defined as the presence of endometrial glands and stroma within the myometrium. The true prevalence is unknown and has been reported to range from 1 to 70%. It has a significantly negative impact on women's quality of life, causing abnormal uterine bleeding, dysmenorrhea, and chronic pelvic pain. The definitive treatment for adenomyosis is hysterectomy, although it does not contemplate patients who wish to preserve their fertility. The aim of this paper is to discuss the latest evidence on the surgical techniques for the treatment of adenomyosis published in medical-scientific databases.

METHOD

A comprehensive literature search for articles published from 1996 to 2017 related to surgery for adenomyosis was made in Pubmed, Medline, the Cochrane Library, and Google Scholar, in English, by the following MeSH terms: adenomyosis, surgery, pathogenesis, dysmenorrhea and infertility.

RESULTS

There is extensive evidence on several surgical approaches for the improvement of adenomyosis-related symptoms; however, there is no robust evidence that they are effective for infertility.

CONCLUSION

The management of adenomyosis is quite complex and controversial. Complications after extensive uterine reconstruction, such as uterine rupture, should be considered and discussed with the patient. There are still limited data to support surgery effectiveness, especially for infertility, and further well-designed studies are required.

Ultrasound-guided transcervical radiofrequency ablation for symptomatic uterine adenomyosis

OBJECTIVE

To retrospectively evaluate the midterm outcomes of transvaginal ultrasound-guided radiofrequency ablation (RFA) for the treatment of symptomatic uterine adenomyosis.

METHODS

87 patients with symptomatic uterine adenomyosis, who met the inclusion criteria, were enrolled in our study from January 2013 to October 2015. All of the patients underwent transvaginal ultrasound-guided RFA and were followed up for 12 months. Assessment end points included uterus volume reduction rate, lesion regression rate, dysmenorrhoeal score, symptom severity score (SSS) and adverse events.

RESULTS

In all 87 patients, 81 patients fulfilled the follow-up evaluations post-ablation. The mean uterine volume reduction rate was 35.8% at 1 month, 40.8% at 6 months and 41.2% at 12 months post-ablation. Dysmenorrhoea and SSS statistically significantly declined. Reintervention rate was 18.5%. Two patients developed intrauterine adhesion after ablation. No serious complications including penetration or burn injuries of the nearby organs were observed.

CONCLUSION

Ultrasound-guided RFA might be a safe and effective minimally invasive alternative in the treatment of symptomatic adenomyosis. Advances in knowledge: This is the first study to evaluate the efficacy and safety of ultrasound-guided RFA for the treatment of adenomyosis to our knowledge. This is also the first study to provide various changes of intrauterine cavity after this treatment.

Efficacy of laparoscopic adenomyomectomy using double-flap method for diffuse uterine adenomyosis

Background

Adenomyomectomy has recently been considered the priority option for the treatment of adenomyosis, however, the surgical efficacy and modes are still debated. We aimed to evaluate the efficacy of laparoscopic adenomyomectomy using a double-flap method for the treatment of uterine diffuse adenomyosis when compared with conventional laparoscopic adenomyomectomy.

Methods

Laparoscopic adenomyomectomy using the conventional method (group A, n = 48) and the double-flap method (group B, n = 46) to treat diffuse uterine adenomyosis, respectively. Visual analog scale (VAS), menstrual amount, serum CA125 levels, and uterine volume were comparatively analyzed in both groups.

Results

The VAS scores, menstrual amount, serum CA125 levels, and uterine volume at 12 or 24 months after surgery significantly reduced in group B than in group A (P < 0.05); these parameters were statistically decreased in both groups after surgery compared with those obtained before surgery (P < 0.001). Moreover, serum CA125 levels and uterine volume at six months of follow up were significantly lower in group B than in group A (P < 0.01). In addition, blood loss during surgery was similar in groups A and B (P > 0.05), although the operative time was significantly longer in group B than that in group A (P < 0.05).

Conclusions

Laparoscopic adenomyomectomy using the double-flap method may be an effective technique to treat uterine diffuse adenomyosis.

Value of magnetic resonance imaging in diagnosis of adenomyosis and myomas of the uterus

STUDY OBJECTIVE

To estimate the diagnostic performance of magnetic resonance imaging (MRI) in detection of myomas and adenomyosis of the uterus.

DESIGN

Prospective cohort observational study (Canadian Task Force classification II-2).

SETTING

Department of obstetrics and gynecology, tertiary academic hospital.

PATIENTS

One hundred fifty-three consecutive women with an enlarged uterus accompanied by gynecologic symptoms and/or with an asymptomatic pelvic mass.

INTERVENTION

Total abdominal hysterectomy. All patients underwent MRI before the operation.

MEASUREMENTS AND MAIN RESULTS

The sensitivity, specificity, positive, and negative predictive value of MRI for the diagnosis of uterine pathology was calculated using histologic findings as the standard criterion for final diagnosis. Receiver operating characteristics curves were constructed to describe the diagnostic performance of MRI. In the diagnosis of myomas, MRI demonstrated sensitivity of 94.1%, specificity of 68.7%, PPV of 95.7%, and NPV of 61.1%. In the diagnosis of adenomyosis, MRI demonstrated sensitivity of 46.1%, specificity of 99.1%, PPV of 92.3%, and NPV of 88.5%. The area under the curve (AUC) for the diagnostic performance of MRI in the detection of myomas and adenomyosis was 0.81 and 0.73, respectively. Uterine sarcoma was diagnosed in 5 patients; in these cases, MRI demonstrated sensitivity of 60.0%, specificity of 99.2%, PPV of 75.0%, and NPV of 98.4%. The AUC for MRI in the diagnosis of uterine sarcomas was 0.80.

CONCLUSIONS

MRI exhibits a high AUC for the diagnosis of both adenomyosis and myomas. The PPV of MRI in the diagnosis of adenomyosis and myomas of the uterus is high as well. MRI seems to be a useful technique in everyday clinical practice in the diagnostic approach of these common conditions, enabling clinicians to select the most appropriate management.

Adenomyosis reduces pregnancy rates in infertile women undergoing IVF

High-resolution transvaginal ultrasound has facilitated the diagnosis of adenomyosis. This study determined the prevalence of this finding in infertile women and its effect on the outcome of IVF/intracytoplasmic sperm injection (ICSI). This prospective study evaluated 275 consecutive women, commencing IVF/ICSI for the first time. Inclusion criteria were adequate ovarian reserve. Women with fibroids or a previous myomectomy were excluded. All women were screened for adenomyosis by transvaginal ultrasound on three separate occasions. The control group included 256 women and the adenomyosis group included 19 women. There was no significant difference in the ages of women, FSH, cause of infertility, body mass index, total dose of gonadotrophin used and number of oocytes collected between the two groups. However, women with adenomyosis had a higher mean antral follicle count (P=0.006). The clinical pregnancy rate (22.2% versus 47.2%) and ongoing pregnancy rate (11.1% versus 45.9%) were significantly lower in women with adenomyosis and the miscarriage rate (50.0% versus 2.8%) was significantly higher in women with adenomyosis (all P<0.001). Ultrasound evidence of adenomyosis is found in a significant number of women presenting with infertility and has a negative impact on the outcome of IVF/ICSI. This paper suggests that a common condition known as adenomyosis is associated with a reduced success following fertility treatment such as IVF. The diagnosis of adenomyosis has been greatly facilitated by the advent of high-resolution transvaginal ultrasound. This was a study including 275 consecutive women who were commencing IVF for the first time. Comparing women who did not have adenomyosis and those that did, the clinical and ongoing pregnancy rates were both lower in women with adenomyosis (22.2% versus 47.2% and 11.1% versus 45.9%, respectively). So, fewer women with adenomyosis became pregnant and had an ongoing pregnancy. The miscarriage rate was higher in women with adenomyosis compared with those without (50.0% versus 2.8%). We conclude that ultrasound evidence of adenomyosis is found in a significant number of women presenting with infertility and has a negative impact on the outcome of IVF.
