The International HS Severity Score System (IHS4) is widely used to assess HS severity by counting inflammatory nodules, abscesses, and draining fistulas/tunnels. However, traditional clinical examinations may underestimate HS severity due to the presence of subclinical lesions. This study aims to enhance the accuracy of HS severity assessment by incorporating ultra-high frequency ultrasound (UHFUS) to detect subclinical lesions, such as microtunnels.</p><p><strong>Methods: </strong>A cohort of 122 patients with HS (75 females and 47 males) was evaluated.

Ultrasound images were analyzed at 10% MVE intervals. Nerve circularity, width, height, and cross-sectional area were measured to assess deformation.

The study's focus was on evaluating outcomes including visual analog scale (VAS) scores for dysmenorrhea, measurements of uterine and lesion volumes, menstrual blood loss, and the rate of disease recurrence. The findings from both direct and indirect comparisons, which were quantitatively assessed using weighted mean differences or relative risk along with their respective 95% confidence intervals, were graphically depicted in forest plots. Additionally, the ranking probability was illustrated, which indicated the likelihood of various high-intensity-focused ultrasound (HIFU) combination therapies being the most effective across each measured outcome. In the final analysis, this network meta-analysis encompassed a total of 31 articles. The results showed that HIFU combined with gonadotropin-releasing hormone agonist (GnRH-a) and progestin was more effective to decrease VAS score for dysmenorrhea than other combined therapies. HIFU combined with progestin was superior to other combined therapies in decreasing uterine volume, lesion size, and recurrence rate. HIFU combined with mifepristone was more effective to reduce menstrual volume compared to other combined therapies. The analysis suggests that regimens incorporating HIFU along with GnRH-a and progestin, or HIFU combined with progestin or HIFU combined with mifepristone might offer superior benefits in the clinical management of adenomyosis.
