Is it better to do the gastric bypass through a standard incision, a very small incision (mini-lap), or laparoscopically? There are pros and cons. In general, laparoscopy virtually eliminates two common postoperative complications: wound infections and hernias. The frequency of bowel obstructions and leaks is increased from about one in 35 to about one in 15. The results with the small incision are intermediate.

Yes, but it would take another operation and it is not advisable.

As with any surgical procedure there are risks. The most common complications are wound infections, strictures, and hernias.

Any abdominal operation sets the stage for a possible bowel obstruction the lifetime frequency of which is approximately 8%. Vitamin and mineral deficiencies can occur if calcium, B12, and iron supplements are not taken as prescribed. Less commonly protein deficiency can occur.
