New surgical technique of laparoscopic resection of adenomyosis under real-time intraoperative ultrasound elastography guidance: A case report

Case Report: The first case of successful pregnancy and live birth following laparoscopic resection of adenomyosis under real-time intraoperative ultrasound elastography guidance

Objective

Adenomyosis-related infertility is increasingly being diagnosed, and surgical intervention has been suggested to improve fertility. Elastography, a noninvasive ultrasound technique, is promising for diagnosing and guiding the resection of adenomyosis. This report presents the first case of successful delivery after twin pregnancies achieved with IVF following intraoperative elastography-guided laparoscopic adenomyomectomy.

Case report

A 35-year-old Japanese woman with uterine adenomyosis received a gonadotropin analog before surgery. Preoperative MRI revealed a 5.0 × 7.0 cm adenomyoma, leading to scheduled laparoscopic adenomyomectomy with intraoperative elastography. During surgery, elastography ensured the complete resection of the adenomyotic tissue while preserving the endometrium. Postoperative MRI confirmed the absence of residual adenomyosis. The patient underwent in vitro fertilization and embryo transfer, leading to a successful twin pregnancy after double blastocyst transfer. Despite a stable perinatal course, she required hospitalization to prevent preterm labor. At 32 weeks, an elective cesarean section delivered healthy twins. The intra- and post-operation was uncomplicated, and the patient and infants had an optimal health.

Conclusion

This is the first reported case of a twin pregnancy resulting from vitrified-warmed embryo transfer after elastography-guided laparoscopic adenomyomectomy, culminating in a successful delivery via cesarean section. This technique allows precise resection and mitigates the risks of uterine rupture and placenta accreta spectrum disorders. Although promising, further studies are required to validate the safety and efficacy of this innovative surgical approach.

Laparoscopic Adenomyomectomy under Real-Time Intraoperative Ultrasound Elastography Guidance: A Case Series and Feasibility Study

BACKGROUND

This study aimed to examine the clinical characteristics of 11 patients undergoing laparoscopic adenomyomectomy guided by intraoperative ultrasound elastography and this technique's feasibility.

PATIENTS AND METHODS

Eleven patients undergoing laparoscopic adenomyomectomy using ultrasound elastography for adenomyosis at Kawasaki Medical School Hospital in Okayama, Japan between March 2020 and February 2021 were enrolled. Operative outcomes included operative time, operative bleeding, resected weight, operation complications, percent change in hemoglobin (Hb) values, and uterine volume pre- and postoperatively. Dysmenorrhea improvement was evaluated by changes in visual analog scale (VAS) scores pre- and 6- and 12-months postoperatively.

RESULTS

The median operative time and bleeding volume was 125 min (range, 88-188 min) and 150 mL (10-450 mL), respectively. The median resected weight was 5.0 g (1.5-180 g). No intraoperative or postoperative blood transfusions or perioperative complications were observed. The median changes in uterine volume, Hb value, and VAS score were -49% (-65 to -28%), -3% (-11 to 35%), and -80% (-100 to -50%), respectively. The median follow-up period post-surgery was 14 months (7-30 months). Adenomyosis recurrence was not observed in the patients during the follow-up period.

CONCLUSIONS

Laparoscopic adenomyomectomy using ultrasound elastography guidance is minimally invasive and resects as many adenomyotic lesions as possible.

Trocar-site hernia following laparoscopic salpingo-oophorectomy in a middle-aged Japanese woman: an initial case report after 40 years of experience at a single center and a brief literature review

Background

In gynecology, the number of laparoscopic surgeries performed has increased annually because laparoscopic surgery presents a greater number of advantages from a cosmetic perspective and allows for a less invasive approach than laparotomy. Trocar site hernia (TSH) is a unique complication that causes severe small bowel obstruction and requires emergency surgery. Its use has mainly been reported with respect to gastrointestinal laparoscopy, such as for cholecystectomy. Contrastingly, there have been few reports on gynecologic laparoscopy because common laparoscopic surgeries, such as laparoscopic salpingo-oophorectomy, are considered low risk due to shorter operative times. In this study, we report on a case of a woman who developed a TSH 5 days postoperatively following a minimally invasive laparoscopic surgery that was completed in 34 min.

Case presentation

A 41-year-old woman who had undergone laparoscopic salpingo-oophorectomy 5 days previously presented with the following features of intestinal obstruction: persistent abdominal pain, vomiting, and inability to pass stool or flatus. A computed tomography scan of her abdomen demonstrated a collapsed small bowel loop that was protruding through the lateral 12-mm port. Emergency surgery confirmed the diagnosis of TSH. The herniated bowel loop was gently replaced onto the pelvic floor and the patient did not require bowel resection. After the surgical procedure, the fascial defect at the lateral port site was closed using 2-0 Vicryl sutures. On the tenth postoperative day, the patient was discharged with no symptom recurrence.

Conclusions

The TSH initially presented following laparoscopic salpingo-oophorectomy; however, the patient did not have common risk factors such as obesity, older age, wound infection, diabetes, and prolonged operative time. There was a possibility that the TSH was caused by excessive manipulation during the tissue removal through the lateral 12-mm port. Thereafter, the peritoneum around the lateral 12-mm port was closed to prevent the hernia, although a consensus around the approach to closure of the port site fascia had not yet been reached. This case demonstrated that significant attention should be paid to the possibility of patients developing TSH. This will ensure the prevention of severe problems through early detection and treatment.

A Case of Elastography-Assisted Laparoscopic Fertility Preservation for Severe Deep Endometriosis Causing Ureteral Stenosis and Subtype II Adenomyosis

Adenomyosis is commonly treated by total hysterectomy. Adenomyomectomy is considered for women of reproductive age who wish to preserve their fertility. However, a high recurrence rate following adenomyomectomy has been reported because complete removal of the lesion is difficult, and uterine rupture during pregnancy remains a complication. We previously reported that laparoscopic adenomyomectomy using a cold knife prevented thermal damage to the myometrium and elastography to avoid residual lesions. Here, we report the case of a patient who underwent complete resection of a subtype II adenomyosis and resection of deep endometriosis (DE) with the closure of the pouch of Douglas. The patient was 31 years old, had severe dysmenorrhea, and had left ureteral stenosis and subtype II adenomyosis associated with the closure of the pouch of Douglas by the DE. After resection of the DE posterior wall adenomyosis, residual lesions were confirmed by laparoscopic real-time elastography. Eight weeks after surgery, postoperative transvaginal ultrasound showed that the myometrium had shrunk from 28 to 22.7 mm, and the hydronephrosis had disappeared, although a stent remained necessary. In this study, we report the complete resection of subtype II adenomyosis and DE, combined with elastography to visualize the lesions during resection.

A Feasible Technique in Laparoscopic Excision for Juvenile Cystic Adenomyosis: A Case Report, Literature Review, and Surgical Video

Background: Juvenile cystic adenomyosis (JCA) is a rare uterine lesion. We present the case of a young woman who was diagnosed with JCA and subsequently managed with laparoscopic cyst removal with sharp and blunt dissection. Moreover, we provide a literature review and a surgical video. Case: A 22-year-old nulliparous woman presented with severe dysmenorrhea and was assessed using contrast-enhanced abdominal computed tomography, transvaginal ultrasonography and pelvic magnetic resonance imaging, and diagnosed with a cystic lesion on the left side of the myometrium. She underwent laparoscopic cyst excision and uterine reconstruction. Histology was suggestive of JCA. The dysmenorrhea resolved postoperatively. Conclusion: Surgical resection is the first choice of treatment for cystic adenomyosis, and a laparoscopic approach using scissor forceps is effective.

Current and Prospective Treatment of Adenomyosis

(1) Background: Adenomyosis is a poorly understood entity which makes it difficult to standardize treatment. In this paper we review and compare the currently approved medical and surgical treatments of adenomyosis and present the evidence behind them. (2) Methods: A PubMed search was conducted to identify papers related to the different treatments of adenomyosis. The search was limited to the English language. Articles were divided into medical and surgical treatments. (3) Results: Several treatment options have been studied and were found to be effective in the treatment of adenomyosis. (4) Conclusions: Further randomized controlled trials are needed to compare treatment modalities and establish a uniform treatment algorithm for adenomyosis.
