PURPOSE: Preoperative imaging evaluation may be useful for determining the position of recti abdominis muscles before their correction. The purpose of this study is to evaluate the accuracy of ultrasonography to measure the width of rectus abdominis muscle diastasis. METHODS: Rectus diastasis was measured by ultrasonography preoperatively in 20 females. Rectus diastasis was measured in seven levels along the anterior rectus sheath by ultrasound after sustained deep inspiration and after expiration. Rectus diastasis, at the same levels, was also measured after its exposition during abdominoplasty by two independent observers, using a surgical compass. These values were compared using Wilcoxon's statistical text, for non independent values. RESULTS: There was no significant difference between the values obtained by ultrasound and those measured during surgery in the supra-umbilical levels and at the level of the umbilicus. However, below the umbilicus these values differed significantly, showing smaller values in the imaging evaluation. CONCLUSION: Ultrasonography is an accurate method to measure rectus diastasis above the umbilicus and at the umbilical level.

PURPOSE: The aim of the present study was to assess, in cadavers, the resistance to medial traction of the posterior and anterior layer of the rectus abdominis muscle sheath. METHODS: An anatomical, prospective, self-controlled study was carried out in 20 male cadavers. An evaluation of the tension of the posterior and anterior layers of the rectus abdominis muscle sheath was performed following anatomical dissection of these structures. The traction necessary to advance the tissue ten millimeters was assessed using an analogic dynamometer. RESULTS: There was no significant statistical difference between the necessary traction at various levels of the anterior and posterior layers of the rectus sheath. However, medial advancement of the anterior layer of the rectus sheath required more traction strength than did advancement of the posterior layer to the midline. CONCLUSION: There is no difference in the tensile strength in the various levels of the anterior and posterior layers of the rectus sheath; however, medial advancement of the the anterior layer required more traction strength.

The Relationship

Abstract Background tummy tuck surgery, also known as abdominoplasty, removes excess fat and skin and, in most cases, restores weakened or separated muscles creating and abdominal profile that is smoother and firmer. Diastasis recti means the belly sticks out because the space between left and right belly muscles has widened. The most notable symptom of anterior abdominal wall weakness or diastasis recti is a noticeable protrusion in the stomach. This protrusion is caused by weakness and separation of the muscles in the mid-abdomen. Objective It was to evaluate the relationship between the distance of recto-fascial or recto-fascial diastasis placation and intra-abdominal pressure changes during and immediately after abdominoplasty. Patient and Methodology In this study we demonstrated if there was relation between rectus diastasis width and the increase of intra-abdominal pressure, to evaluate this correlation before and immediately after the plication of anterior rectus sheath in abdominoplasty. Seventy five meeting the inclusion criteria were selected. Results This study enrolled 75 healthy female patients, the study took place at Al-Jamila Hospital, performed in a period of 10 months, starting from March 2017 till December 2017.

PURPOSE: To assess the collagen content and types in the rectus abdominis muscle of cadavers of different ages. METHODS: Forty fresh adult male cadavers, at room temperature, were obtained from the Institute of Legal Medicine of Franca and dissected within 24 hours of death. The cadavers were divided into two groups: Group A (n=20), 18 to 30 years of age, and Group B (n=20), 31 to 60 years of age. Bilateral incisions were made in the middle portion of anterior rectus sheath 3 cm superiorly and 2 cm inferiorly to the umbilicus and four fragments of the rectus abdominis muscle were dissected. The samples were fixed in 10% buffered formalin and sent for immunohistochemical analysis to determine collagen content and types. RESULTS: Immunohistochemical results revealed higher amounts of type I and type III collagen in Group A. However, no difference in the amount of type IV collagen was found between the groups. CONCLUSION: The amount of type I and type III collagen was higher in group A.

SUMMARY In nine adult female ferrets the thyroid gland was autotransplanted to the deep surface of the rectus abdominis muscle. Six animals were subjected to sham operations in which both the thyroid gland and the deep surface of the rectus abdominis muscle were exposed, but the thyroid was not actually transplanted. In the spring of 1961 the dates when signs of oestrus appeared in these two groups of animals were compared. There was no significant difference between the two groups; nineteen normal animals which were also kept under observation became oestrous at the same time. From 17 November 1961 onwards, the animals were exposed to artificial light from 4.30 to 10.30 p.m. daily in addition to ordinary daylight. In this part of the experiment sixteen normal animals were kept under observation together with the two groups of animals which had been treated surgically. Again, there was no significant difference between the dates on which signs of oestrus appeared in the three groups.

The use of swines as an experimental model to correct rectus diastasis by laparoscopy is described on this article. The correction of this deformity was achieved by the plication of the posterior rectus sheath with the insertion of two trocars on the inferior abdominal fold. One trocar was placed in the midline whereas the other was inserted laterally to the right rectus muscle. A continuous suture was made on the posterior rectus sheath with 0-Polipropilene. This suture was anchored at the anterior rectus sheath under direct vision. An incision of all layers was performed on the flank and the abdominal wall was turned inside out so that the area of plication could be assessed and evaluated. The experimental model described showed to be feasible to demonstrate the correction of rectus diastasis by laparoscopy.

PURPOSE: The tension at the aponeurotic edges of abdominal wall defects is an important factor of dehiscence and incisional hernia formation. The purpose of this study is to map and compare the traction force necessary for medial mobilization in various levels of the anterior rectus sheath in cadavers. METHODS: Twenty four adult male cadavers, raging from 22 to 59 years old, with the abdominal wall intact and without prior preservation techniques, were dissected. A complete excision of the linea alba was performed. Traction loops of 10 mm in diameter were made in the anterior rectus sheath and were placed: 2, 4, 6 and 8 cm below the lower edge of the umbilicus and 3, 6 and 9 cm above the upper edge of the umbilicus. Each loop was mobilized 10 mm in the medial direction, using an analog dynamometer. The values obtained in each level were compared using Friedman's analysis of Variance for p < 0.05. RESULTS: The average traction values obtained at the various levels were compared and there was no statistical significant difference. CONCLUSION: There is no variation in tension along the whole extension of the anterior rectus sheath.
