1. Treatment of diastasisrecti with abdominal protrusion, muscular laxity, or associated ventral,orincisionalhernia, using a very large prosthesis, and an extensive dermo-lipectomieMarc. Soler, M.D. (Cagnes-sur-Mer) Michel. Audion, M.D. (Nice), Diastasisrecti is characterised by an excessively large space between 1 the rectus abdominus and widening of the linea alba. This anatomical disorder is often observed in cases of abdominal 2 protrusion and muscular laxity, or in conjunction with other lesions of the anterior abdominal wall, such as umbilical or epigastric hernia, or incisionnal hernias.3 Diastasis: définition before 45years old: 1: 10mm, 2: 27mm, 3: 9mmafter 45years old: 1: 15mm, 2: 27mm, 3: 14mm Anatomy of the Anterior Abdominal Wall Hardeep Singh Ahluwalia, MD, J. Pim Burger, MD, Thomas H. Quinn, PhD In reparative surgery to improve the aesthetic appearance of the abdomen, the authors have drawn upon traditional procedures performed to treat hernia or to repair incisional hernias, by using parietal reinforcement prostheses. The treatment proposed here is not designed to address isolated diastasis. Instead, it deals with laxity in the abdominal muscles in general by treating muscular relaxation and its associated pathologies. The procedure involves placement of very large parietal reinforcement prosthesis in the preperitoneal cleavable space in the lower part of the preperitoneum, preaponeurosisretromuscular in the upper part of the abdomen. It’s the addition of the Stoppa and  the Rives procédure. The authors recommend the use of prosthesis with a large mesh. RIVES et STOPPA procedure   The procedure, in use since 1995, includes the following:  -       Detachments in the cleavable spaces -     -       Results-conclusion In 40 cases, using selected materials, the authors have observed no specific surgical complications relative to the surgical technique used, and the mesh used.
