Sclerotherapy of peripheral low-flow vascular malformations: technical aspects and mid-term clinical outcome

Vascular anomalies of the limb and trunk in children: a retrospective comparative study of endoscopic surgery and open surgery

BACKGROUND

Endoscopic resection has been reported for vascular anomalies (VA) previously. However, there is no study comparing endoscopic resection surgery (ERS) with open resection surgery (ORS) in children. We aimed to compare clinical and cosmetic outcomes between two approaches in pediatric VA.

METHODS

Between June 2018 and June 2023, 138 pediatric VA patients undergoing ERS or ORS were retrospectively reviewed. Propensity score matching (PSM) was performed to minimize selection bias. The Scar Cosmesis Assessment and Rating (SCAR) Scale and numerical rating scale (NRS) based on patient satisfaction were used for cosmetic assessment.

RESULTS

After PSM for age, depth of lesion, size of lesion, and site of surgery, 72 patients (ERS = 24, ORS = 48) were analyzed. Patients undergoing ERS had longer operative time (164.25 ± 18.46 vs. 112.85 ± 14.26 min; P < 0.001), less estimated blood loss (5.42 ± 2.15 vs. 18.04 ± 1.62 ml; P < 0.001), and shorter median hospital stay (4.50 [3.00-5.00] vs. 6.00 [5.00-6.00] days; P < 0.001). The follow-up time was 8.04 ± 1.23 month for ERS group and 8.56 ± 1.57 month for ORS group. For aesthetic results, the median overall SCAR score in ERS was lower than that in ORS (2 [1-3] vs. 5 [4-5]; P < 0.001), and the subscales of "scar spread," "dyspigmentation," "track marks or suture marks," and "overall impression" were better. The median NRS score was higher (8 [7-8] vs. 6 [5-6]; P < 0.001) and length of scars was shorter (2.18 ± 0.30 vs. 8.75 ± 1.98 cm; P < 0.001) in ERS group than those in ORS group. The incidences of total complications and recurrence showed no significant difference between two groups.

CONCLUSIONS

Endoscopic surgery can be a safe and effective option for pediatric VA in the limbs and trunk. It offers the advantages of improving aesthetic outcomes and reducing postoperative wound healing time.

Ultra-high frequency ultrasound (UHFUS) applications in Sjogren syndrome: narrative review and current concepts

Primary Sjogren's syndrome (SS) is a systemic autoimmune chronic inflammatory disease with predominant involvement of the exocrine glands, particularly the salivary glands (SGs). The role of salivary glands ultrasound (SGUS) in the work-up of patients with primary Sjogren syndrome (SS) is progressively increasing due to its useful support in diagnosis and follow-up as a widely available, repeatable, non-invasive and safe technique. Although SGUS is not yet included in the dominant primary SS classification, several studies supported its inclusion in the American College of Rheumatology/European League Against Rheumatism criteria. In this context, a novel imaging technique, ultra-high frequency ultrasound (UHFUS), is being explored. Compared to the frequencies used in conventional ultrasound (US) (up to 22 MHz), UHFUS operates with higher frequencies (30-100 MHz) allowing for outstanding image resolution, up to 30 µm. UHFUS permits the scan of both major and minor SGs, opening new avenues for the integration of tissue and imaging biomarkers. Although further studies are needed to confirm its role, this novel imaging technique might lead to several potential improvements, including earlier diagnosis, reduction of unnecessary and inadequate biopsies and better management and follow-up of patients with primary SS.
