Abstract
INTRODUCTION: Raising the temperature of abdominal wall endometriosis lesions contributes to an effective ablation; however, providing sufficient protection to the surrounding tissues remains a challenge. In this study, we aimed to combine ultrasound and single-port laparoscopic images to not only achieve complete ablation of abdominal wall endometriosis lesions but also protect surrounding tissues from damage. The adverse events and complications were Common Terminology Criteria for Adverse Events grade 1 or Society of Interventional Radiology classification grade A. MATERIAL AND METHODS: This historical study included 30 patients with abdominal wall endometriosis who underwent ultrasound and single-port laparoscopic-guided microwave ablation at the Ultrasonography and Gynecology Department of the Wuhan Central Hospital between October 2017 and February 2022. Ultrasonography and magnetic resonance imaging were used to evaluate the number, size, and depth of the lesions. Pain levels were assessed using a visual analog scale. Subsequently, ultrasound and single-port laparoscopic-guided microwave ablation of the lesions was performed, and patients were followed up to monitor the lesion volume and pain. RESULTS: One patient experienced an intra-abdominal wall burn that was detected by single-port laparoscopy, and ablation was stopped immediately. No other complications were recorded. Following surgery, the lesion volume decreased and was lower than the preoperative lesion volume at 1 year postoperatively (1.6 ± 1.3 vs. 4.0 ± 3.6 cm(3); p < 0.05). Visual analog scale scores revealed that, compared with preoperative levels, pain was reduced significantly at all postoperative time points (p < 0.01). The recurrence rate was 16.7% (5/30). CONCLUSIONS: The addition of single-port laparoscopy to ultrasound-guided microwave ablation may allow greater protection of the surrounding tissues, particularly in cases involving deep lesions, and may, therefore, represent a promising clinical treatment strategy.
