Resumo
A diástase do reto abdominal (DRA) é uma condição frequente da parede abdominal anterior, com impacto funcional e estético, cujo tratamento cirúrgico tem evoluído progressivamente para abordagens menos invasivas. Entre essas, a técnica MILA (Minimally Invasive Lipoabdominoplasty) destaca-se por permitir a correção da diástase por via endoscópica no plano supra-aponeurótico. O presente artigo tem como objetivo descrever detalhadamente a técnica MILA com preservação do ligamento umbilical, enfatizando seus aspectos técnicos e anatômicos, bem como os critérios de seleção e os passos cirúrgicos fundamentais para sua reprodutibilidade. Trata-se de uma descrição técnica, sem análise de desfechos clínicos ou comparação entre métodos. A preservação do ligamento umbilical constitui um diferencial da técnica, contribuindo para a manutenção da anatomia umbilical e do contorno abdominal natural. A descrição sistematizada da MILA pode auxiliar cirurgiões na padronização da técnica e servir de base para futuros estudos clínicos comparativos.

Abstract
Diastasis rectus abdominis (DRA) is a frequent condition of the anterior abdominal wall, with functional and aesthetic impact, whose surgical treatment has progressively evolved to less invasive approaches. Among these, MILA (Minimally Invasive Lipoabdominoplasty) stands out for allowing the correction of diastasis endoscopically in the supra-aponeurotic plane. The present article details the MILA technique with umbilical ligament preservation, emphasizing its technical and anatomical aspects, as well as the selection criteria and the fundamental surgical steps for its reproducibility. This is a technical description, without analysis of clinical outcomes or comparison between methods. The preservation of the umbilical ligament is a differential of the technique, contributing to the maintenance of the umbilical anatomy and the natural abdominal contour. The systematized description of MILA can help surgeons standardize the technique and serve as a basis for future comparative clinical studies.
