An alternative to primary wound suturing by single sutures or purse string sutures (PSS) is applying incisional negative pressure wound therapy (iNPWT). The aim of the following systematic review and meta-analysis was to assess and compare clinical outcomes in patients after PSS and iNPWT use. &lt;b&gt;Approach:&lt;/b&gt; The aim of the study was to find relevant clinical data comparing outcomes of iNPWT and primary wound closure after intestinal ostomy closure. The search was conducted using the MEDLINE/PubMed, ScienceDirect, EMBASE, Scopus, Cochrane Controlled Register of Trials, SciELO, and Web of Science databases and took place up to November 12, 2022. The authors did not use date or language filters. Statistical analysis was performed using Review Manager 5.4 (The Cochrane Collaboration, 2020, London, UK). The authors conducted a meta-analysis of the following four parameters: wound healing time (WHT), surgical site infections (SSIs), complications, and length of hospital stay (LOS). Odds ratios (OR) and inverse variance (IV) were generated with 95% confidence intervals (CI). The meta-analysis was registered in the International Prospective Register of Systematic Reviews database under registration number CRD42023391640. &lt;b&gt;Results:&lt;/b&gt; The analysis revealed that the iNPWT group and the control group did not differ significantly with regard to the WHT parameter (Z = 2,73; &lt;i&gt;p&lt;/i&gt; = 0.006; χ&lt;sup&gt;2&lt;/sup&gt; = 0.37, &lt;i&gt;df&lt;/i&gt; = 1, &lt;i&gt;p&lt;/i&gt; = 0.54, &lt;i&gt;I&lt;/i&gt;&lt;sup&gt;2&lt;/sup&gt; = 0%).

Payment limits for each CTP were obtained via the Healthcare Common Procedure Coding System Q codes and formulated as cost inputs into a cost-utility model published for treatment of Wagner 1 diabetic foot ulcers using dehydrated human amnion and chorion allograft versus standard of care (SOC). Additional changes to cap the number of CTP applications and adjustments for recent inflation were made. The literature was searched for other cost-utility models in other diabetes-related diseases as a comparison. <b>Results:</b> When the payment limit was ≤$140 per square centimeter, interventions were dominant (less costly, better outcomes) compared with SOC. When the limit exceeded $430 per square centimeter, the cost-effectiveness threshold of $100,000/QALY was exceeded. Newer Q codes are generally much more expensive and likely to not be cost-effective, similar to the results for many other chronic diabetes-related diseases . <b>Innovation:</b> This study presents decision makers with tools, by which they can determine as to whether a given CTP is likely to be cost-effective for patients. <b>Conclusion:</b> Over a third of all CTPs will very likely result in noncost-effective interventions.

The urgent need for accessible and cost-effective therapeutic alternatives, especially for underserved populations, has driven interest in novel approaches such as noninvasive splenic stimulation using pulsed-focused ultrasound (pFUS). This technique targets systemic inflammation, a key factor in delayed wound healing, offering a potential shift in burn care management. <b>Recent Advances:</b> Preclinical studies have shown that pFUS applied to the spleen can accelerate wound healing by activating the cholinergic anti-inflammatory pathway, promoting pro-angiogenic and anti-inflammatory responses. While current treatments-including biologics, antioxidants, and growth factors-have limitations, pFUS presents a noninvasive alternative. One interventional study and ongoing clinical trials are now investigating its application in burn wound care, marking an important step toward clinical translation. <b>Critical Issues:</b> Despite encouraging results, research on splenic stimulation for wound healing remains limited. The small number of studies highlights the need for further investigation into the underlying mechanisms, optimal treatment parameters, and potential risks. Additionally, the scalability and cost-effectiveness of pFUS in diverse clinical settings require thorough evaluation. <b>Future Directions:</b> Ongoing clinical trials will provide critical data on the efficacy and safety of splenic pFUS in burn patients.
