Safety and Effectiveness of Laser or Intense Pulsed Light Treatment for Early Surgical Scar: A Systematic Review and Meta-analysis.

OBJECTIVE: We aimed to investigate the safety and efficacy of laser or intense pulsed light therapy for early treatment of surgical scar. METHODS: A literature search was conducted for relevant prospective, randomized controlled trials published in PubMed, Embase, Web of Science, Cochrane Library, CNKI, WanFang Database, and VTTMS between January 2006 and January 2022. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses checklist was used to extract literature data. The risk of bias was assessed by RevMan. Safety was assessed based on the presence of serious adverse reactions (blisters, infections, burns above the second degree), while effectiveness was assessed using the Vancouver Score Scale. RESULTS: 1512 related articles were preliminarily retrieved, including 1211 English articles and 301 Chinese articles. According to the inclusion criteria and exclusion criteria, 12 articles were selected for this analysis. In total, 475 patients were included (laser group, 238; control group, 236). All studies confirmed that the laser group was superior to the control group. In the subgroup analysis of 7 articles, the standardized mean difference was 1.99 (P = 0.0001). CONCLUSIONS: This meta-analysis demonstrates that laser or intense pulsed light therapy is a safe and effective approach for early surgical scar treatment, resulting in improved scar appearance and minimal adverse reactions. LEVEL OF EVIDENCE I: This journal requires that authors assign a level of evidence to each article.

Clinical study on orthopaedic treatment of chronic osteomyelitis with soft tissue defect in adults.

To investigate the clinical application value of different flap transfer and repair techniques in adult patients with chronic osteomyelitis of limbs complicated with soft tissue defects. According to the characteristics and defects of 21 cases, different plastic surgery was applied, including debridement, negative pressure device, and tissue flap to cover wound. Among 21 cases of chronic osteomyelitis complicated with local soft tissue defect, 15 patients were repaired with sural neurotrophic musculocutaneous flap transfer, 2 patients were repaired with medial plantar skin flap transfer, 2 patients were repaired with ilioinguinal skin flap transfer, 1 patient was repaired with z-forming wound, and 1 patient was repaired with soleus muscle flap combined with full-thickness skin graft. All the 21 patients underwent bone cement implantation after dead bone osteotomy. Among them, 19 patients underwent bone cement replacement with 3D prosthesis within 6 months to 1 year after surgery, and 2 patients carried bone cement for a long time. Early intervention, thorough debridement, removal of necrotic or infection, and then selecting the appropriate wound skin flap coverage are important means of guarantee slow osteomyelitis wound healing and for providing a possible way to permanent prosthesis implantation subsequently.

The use of peritoneal tissue mobilised with a novel laparoscopic technique to reconstruct a neovagina.

The use of the peritoneum to construct the new lining of the vagina was described 40 years ago. However, the technique required open laparotomy and extensive dissection of the peritoneum and this technical difficulty and morbidities associated with the procedure reduced the acceptance of this technique. Subsequently, outcomes achievable from any neo-vaginoplastic techniques for a vaginal deformity, regardless of the aetiology, have been problematic due to peritoneal reflection at the pelvic floor, lack of ideal tissues to line a neovagina, and cicatricial contracture. The advent of the endoscope renewed interest in using peritoneal tissues in vaginal reconstruction, and peritoneal tissue mobilisation using forceps to grasp the tissue from below has been described. Here, we use a novel device to push a segment of mobilised peritoneum caudally into the vault. We have used this technique successfully in 12 individuals with congenital vaginal agenesis. Under laparoscopic guidance and from the pelvic cavity, a novel instrument was used to push peritoneal tissue down to the introitus, incised, and sutured to the margin of the skin and mucous membrane to form a new introitus. All the new peritoneal linings survived and the diameter, depth, and moisture of the neovaginas allowed for satisfactory sexual intercourse and did not produce unpleasant odour or excessive secretion. Advantages of this operative technique include its simplicity, the reduced possibility of severe complications in the abdominal cavity, the avoidance of severe morbidity in the perineal region, and the production of a functional, hygienic vagina. It is our preferred and recommended method to reconstruct the vagina.
