Morel-Lavallee lesion (MLL) of the peri-pelvic region is less common and various treatments have been introduced to manage the lesion. No standard treatment is recommended. We performed a systematic review of literature to (1) identify the classification of peri-pelvic MLL; (2) review the treatments of the lesion and their complications; (3) define the optimal treatment of peri-pelvic MLL.


A systematic search was performed via PubMed, ISI Web of Knowledge, and Embase for English abstract articles from 1966 to 2012. We identified 21 articles detailing 153 patients with peri-pelvic MLL, most of which were level IV studies. The treatments and clinical results were reviewed.


For peri-pelvic MLL patients, surgical intervention was better than conservative therapy. Sclerhodesis method is attended with good outcome in the symptomatic MLL patients without fractures. Patients with peri-pelvic fractures could be managed with local suction drainage or open debridement with dead space closure technique during fracture fixation. The delayed-diagnosis cases might be treated with mass resection when fibrosis capsule was obtained in magnetic resonance imaging.


Peri-pelvic MLL can be treated with various surgical methods depending on the formation of fibrosis capsule and associated injuries. Dead space closure technique is emphasized in the treatment of MLL. Higher quality of literature is required to prove this result in future research.
