Plication of the Rectus Abdominis in Two Planes and in One Continuous Suture Plan

2016-02-04 18:08:23 | BioPortfolio


Thirty women with similar abdominal deformities, who had had at least one pregnancy, were randomized into three groups to undergo abdominoplasty. Plication of the anterior rectus sheath was performed in two layers with 2-0 monofilament nylon suture (control group) or in a single layer with either a continuous 2-0 monofilament nylon suture (group I) or using a continuous barbed suture (group II). Operative time was recorded. All patients underwent ultrasound examination preoperatively and at 3 weeks and 6 months postoperatively to monitor for diastasis recurrence. The force required to bring the anterior rectus sheath to the midline was measured at the supraumbilical and infraumbilical levels.


Inclusion criteria were female gender; 25 to 50 years of age; history of at least one pregnancy; body mass index (BMI) between 18 and 30 kg/m2; desire to undergo abdominoplasty as a single procedure without receiving liposuction or other cosmetic surgeries; deformities of the skin and subcutaneous tissues in the abdominal region; and musculoaponeurotic defect.

Non-inclusion criteria were smoking habit; abdominal wall scar (except for a Pfannenstiel scar related to a Cesarean section); abdominal wall hérnias; history of deep-vein thrombosis; chronic obstructive pulmonary disease; câncer; hypertension; diabetes or other chronic systemic diseases; and use of corticosteroids. Patients lost to follow-up and those who did not undergo ultrasound examination were excluded from the study.

Primary outcome: Get a technique that provides a safe correction with lasting results and in every segment of time.

Secondary clinical outcome: confirms the plication of a single layer as positive in women patients at two years of surgery compared to two planes.

Medical and Biotech [MESH] Definitions

Muscles forming the ABDOMINAL WALL including RECTUS ABDOMINIS, external and internal oblique muscles, transversus abdominis, and quadratus abdominis. (from Stedman, 25th ed)

The muscles that move the eye. Included in this group are the medial rectus, lateral rectus, superior rectus, inferior rectus, inferior oblique, superior oblique, musculus orbitalis, and levator palpebrae superioris.

A long flat muscle that extends along the whole length of both sides of the abdomen. It flexes the vertebral column, particularly the lumbar portion; it also tenses the anterior abdominal wall and assists in compressing the abdominal contents. It is frequently the site of hematomas. In reconstructive surgery it is often used for the creation of myocutaneous flaps. (From Gray's Anatomy, 30th American ed, p491)

The 3d cranial nerve. The oculomotor nerve sends motor fibers to the levator muscles of the eyelid and to the superior rectus, inferior rectus, and inferior oblique muscles of the eye. It also sends parasympathetic efferents (via the ciliary ganglion) to the muscles controlling pupillary constriction and accommodation. The motor fibers originate in the oculomotor nuclei of the midbrain.

Abnormal separation of muscles.
