Will abdominal adhesions grow back after being surgically removed 6 months ago?

Likely. Intra-abdominal adhesions form after most any surgery inside the abdomen. Laparoscopic or minimal surgery may form the least adhesions. Each re-operation increases the amount of adhesions for most people. Adhesions that form are usually benign and do not have consequences. Intestinal blockage can sometimes come from adhesions, and pain is usually not caused by adhesions.
MOST CERTAINLY. Adhesions are internal scars, which cause fixed points within the GI tract, which can be focal points around which intestines can twist or crimp and result in bowel obstruction. Almost all patients who have had surgery or inflammatory abdominal disease form them, and they actually occur very quickly. Fortunately, in only a small percentage of patients do problems develop. Good luck.
