Studies on the endoscopic correction of diastasis recti

Abstract

Recently, we performed a study that showed it is possible to correct rectus diastasis when performed using the laparoscope. A cadaver was used to show the effect of plicating the posterior rectus sheath from within the peritoneal cavity on the external appearance of the abdomen. The abdominal contour improved and the abdominal wall became more tense than before. No excess skin was noted in the midline. Another technique we performed to correct the rectus diastasis by laparoscopy was developed in pigs. Eight animals were used. The width of the diastasis correction varied from 2.8 to 3.5 cm (average of 3.1 cm in the upper abdomen and 3.2 cm in the lower abdomen). The technique that was used will be described in detail. To correct the rectus diastasis by laparoscopy, we performed a running suture in the posterior rectus sheath. For this kind of plication, we feel that a running suture is preferable when compared with the use of staples or interrupted stitches. Some advantages of this technique are: 1) smaller scars; 2) a short operative time; 3) low blood loss; 4) it may be used in patients that did not reap the benefits of any other previously described technique; and 5) it may be performed in association with other laparoscopic procedures such as tubal ligation. Other abdominal wall defects like small hernias may also be corrected by using this technique.
