Abstract

Objectives: To evaluate the diagnostic accuracy of imaging modalities and outcomes of treatment strategies for Morel-Lavallée lesions (MLLs) and provide evidence-based recommendations for optimal management.

Methods: Data Sources: MEDLINE, Embase, and Emcare databases were systematically searched for English-language studies published up to September 2024.

Study selection: Observational studies and randomized controlled trials (RCTs) reporting diagnostic accuracy or treatment outcomes for MLLs were included. Case reports, small series, animal studies, and non-English articles were excluded.

Data extraction: Study quality was assessed using the Methodological Index for Non-randomized Studies (MINORS) tool. Data on demographics, lesion characteristics, imaging modalities, and outcomes were extracted. Lesions were categorized as small (<100 cm3) or large (≥100 cm3) based on volume.

Data synthesis: Descriptive statistics summarized outcomes. Recurrence rates were calculated and pooled proportions compared across treatment modalities.

Results: Twenty-nine studies (928 patients, 964 lesions) were included. MLLs most frequently occurred in the thigh (26.5%), greater trochanter (24.9%), and lumbar region (20.3%). Among smaller lesions (<100 cm3), nonoperative treatment had a low recurrence rate (5.6%), while for larger lesions (>100 cm3), percutaneous management was associated with the highest recurrence rate (15%) compared to other treatment approaches. Operative treatment of large lesions had a 50% recurrence rate in one study, while sclerodesis achieved the lowest rate (4.8%) for lesions averaging 387 cm3, however, this finding is based on a limited number of cases (21 lesions). MRI was the most common single imaging modality reported (n=162 lesions, 19.5%), favoured for its superior soft-tissue characterization. Ultrasound was used in 121 lesions (14.6%) as an accessible initial assessment tool, while CT, often performed incidentally during trauma evaluation, diagnosed 339 lesions (40.9%).

Conclusions: MRI was the most used single modality for diagnosing MLLs. Small, acute lesions were effectively managed nonoperatively. Large lesions (>100 cm3) often required operative management. Sclerodesis appears promising with the lowest recurrence (4.8%), but further studies are needed. Standardized treatment protocols may help improve outcomes and reduce recurrence.

Level of evidence: IV, systematic review.

Morel-Lavallee病变的特点、模式和最佳治疗策略:系统综述。
目的:评价morel - lavallsamac病变(mls)影像学诊断的准确性和治疗策略的效果,为优化治疗提供循证建议。方法:数据来源:系统检索MEDLINE、Embase和Emcare数据库,检索截至2024年9月发表的英语研究。研究选择:纳入报告mls诊断准确性或治疗结果的观察性研究和随机对照试验(rct)。排除病例报告、小系列、动物研究和非英文文章。资料提取:采用非随机研究方法学指数(Methodological Index for non -random Studies,未成年人)工具评估研究质量。提取了人口统计学、病变特征、成像方式和结果的数据。病变被分类为小(数据综合:描述性统计汇总结果)。计算复发率,并比较不同治疗方式的合并比例。结果:纳入29项研究(928例患者,964个病灶)。mls最常发生在大腿(26.5%)、大转子(24.9%)和腰椎(20.3%)。在较小的病变(100 cm3)中,与其他治疗方法相比,经皮治疗与最高复发率(15%)相关。在一项研究中,大病灶的手术治疗复发率为50%,而硬化的复发率最低(4.8%),病灶平均为387 cm3,然而,这一发现是基于有限数量的病例(21个病灶)。MRI是最常见的单一成像方式(n=162个病变,19.5%),因其优越的软组织特征而受到青睐。121个病变(14.6%)使用超声作为初步评估工具,而CT通常在创伤评估中附带使用,诊断出339个病变(40.9%)。结论:MRI是诊断mls最常用的单一方式。小的、急性的病变可以通过非手术有效地处理。大病变(bbb100 cm3)通常需要手术治疗。硬化症的复发率最低(4.8%),但需要进一步的研究。标准化的治疗方案可能有助于改善结果并减少复发。证据等级:IV,系统评价。
