Randomized Controlled Trial of Topical Skin Adhesive vs Nylon Sutures for Incision Closure in Forefoot Surgery

Comparison of 2-octyl cyanoacrylate and n-octyl cyanoacrylate topical skin adhesives for wound closure after ankle fracture surgery: a prospective randomized trial

To date, only a few clinical studies have investigated the differences between 2-octyl cyanoacrylate and n-octyl cyanoacrylate topical skin adhesives (TSAs). This study aimed to compare the outcomes of the two TSAs for wound closure after ankle fracture surgeries. Fifty-six patients were randomized to receive either a 2-octyl or n-octyl cyanoacrylate TSA. At 3 and 6 months after surgery, wound cosmetic outcomes were assessed using the Hollander Wound Evaluation Scale (HWES), and patient satisfaction for wound cosmesis was assessed using the visual analog scale (VAS) and 5-item Likert scale. Functional outcomes at 6 months after surgery were assessed using the Olerud-Molander Ankle Score (OMAS). Fifty-five patients completed the study protocol. Within the follow-up period, no differences were found between the two groups in terms of HWES, VAS, 5-item Likert scale, and OMAS. 2-octyl cyanoacrylate TSA and n-octyl cyanoacrylate TSA were comparable options for wound closure after ankle fracture surgeries in terms of wound cosmesis, patient satisfaction, and functional outcome.

A Comparison of Tissue Adhesive Material and Suture as Wound-Closure Techniques following Carpal Tunnel Decompression: A Single-Center Randomized Control Trial

BACKGROUND

Carpal tunnel syndrome (CTS) is the most common peripheral neuropathy caused by compression of the median nerve in the carpal tunnel. The presented study aimed to evaluate clinical outcomes by comparing two techniques of wound closure following carpal tunnel surgery in subjects randomized to the application of tissue adhesive or sutures.

METHODS

From April 2022 to December 2022, a single-center randomized prospective trial was conducted at the University Hospital of Split in Croatia. The study participants consisted of 100 patients (70 females) aged 61.56 ± 12.03 years, randomly assigned to suture-based wound closure (n = 50) or tissue adhesive-based wound closure (n = 50) with two-component skin adhesive Glubran Tiss 2^®. The outcomes were assessed postoperatively during the follow-up period at intervals of 2, 6, and 12 weeks. A scar assessment was performed using the POSAS (Patient and Observer Scar Assessment Scale) and cosmetic VAS (Visual Analog Scale). The VNRS (Verbal Number Rating Scale) was used to assess pain.

RESULTS

There were significant differences between glue-based wound closure and suture-based wound closure at 2-week and 6-week intervals after the surgery on the POSAS and cosmetic-VAS scales (better aesthetic effect with glue-based wound closure technique where noticed), with less postoperative pain at the same intervals. With the 12-week interval, differences in outcomes were insignificant.

CONCLUSIONS

This trial demonstrated that cyanoacrylate-based adhesion mixtures might be possibly superior in the short term in terms of cosmetic appearance and discomfort compared to conventional skin suturing techniques for the closing of surgical wounds following open CTS decompression, but there was no difference between both procedures in the long term.
