I think it is great you are doing your research, and learning all that you can about your surgery. I personally feel the most secure type of rectus fascia plication (often referred to as "muscle repair") is a double layer technique. I do the first layer in multiple "single" figure-of-8 stitches (also referred to as "interrupted" figure-of-8 stitches), and do a second layer on top that is a running continuous layer. Theoretically if a single stitch is used and it breaks for any reason (such as a sudden forceful cough), or doesn't break but tears through muscle in a portion, then you could lose strength along the entire length of your repair. If the same running stitch breaks in a patient with a second row of multiple single stitches, you maintain the repair. Also, if just one of the single stitches breaks, you still have your single running stitch and all of the rest of the single stitches to hold the repair. An argument against the double layer repair is that is takes more time, and there is more suture material in the abdomen (only a problem in the face of infection). Please keep in mind that there are many other factors involved in the success of a tummy tuck, and you should be able to trust your surgeon with the details such as how many stitches he or she uses. I would recommend researching the credentials of your surgeon, and looking at his or her before-and-after photos before making your final decision. I recommend going with a board certified (or board eligible) plastic surgeon for this type of surgery. Good luck!
