Unlike patients with primary pilonidal sinus, those with recurrent cases often present with more complex sinus tracts, and scarring from previous surgeries increases the complexity of subsequent procedures. Therefore, selecting the appropriate surgical method for patients with recurrent pilonidal sinus requires greater caution. It is essential to reassess these patients to determine whether surgical techniques suitable for primary pilonidal sinus are equally effective for recurrent cases. Laser ablation, an innovative and minimally invasive technique, has emerged as a promising option for managing pilonidal sinus. This procedure uses a circular laser at the tip of a catheter to deliver energy, effectively destroying and ablating the sinus tract while promoting its closure. Previous studies have demonstrated the safety and efficacy of laser ablation in treating primary pilonidal sinus. The objective of this systematic review and meta-analysis is to assess the efficacy and safety of laser ablation in the management of recurrent pilonidal sinus.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Methods: &lt;/strong&gt;This study was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. A comprehensive literature search was carried out using PubMed, Embase, Cochrane Library, Web of Science, and ClinicalTrials.gov. Additionally, the references of all retrieved studies were screened to identify further eligible data. The search included studies published up to June 11, 2024. The primary outcome measure was the healing rate after laser ablation, which served as the metric for evaluating the efficacy of this technique in treating recurrent pilonidal sinus. Secondary outcome measures included the incidence of severe postoperative complications, which were assessed to determine the safety profile of laser ablation. According to the Clavien-Dindo classification of postoperative complications, we define severe complications as those classified as grade IIIb or higher.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Result: &lt;/strong&gt;A total of seven studies were included in this meta-analysis. With the exception of one study published in 2018, the remaining six were published within the past 3 years.

While hospitalized Hispanics with IBD are more likely to be in the lowest quartile for household income (31.6% vs 19.3%, P < 0.01), have a younger median age (37.0 vs 45.0, P < 0.01), and be uninsured (4.3% vs 8.8%, P < 0.01) compared to NHW. Length of admission was similar, yet NHWs had higher rates of mortality (0.3% vs 0.2%, P = 0.01), while total charges for hospitalizations were significantly higher for Hispanic patients (P < 0.01).</p><p><strong>Discussion: </strong>To our knowledge, this is one of the largest US-based studies of Hispanics with IBD. Our findings suggest that among hospitalized IBD patients, Hispanics are more likely to be younger, uninsured, have a lower household income, and are less likely to undergo surgery while having higher hospital charges.</p>","PeriodicalId":13789,"journal":{"name":"International Journal of Colorectal Disease","volume":"40 1","pages":"41"},"PeriodicalIF":2.5,"publicationDate":"2025-02-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11825601/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143414145","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
