If nine out of 10 of your patients were developing post-op infections, would you change your antibiotic and infection control policies? Of course you would. And that's why it's astounding that more isn't done to prevent adhesions, which develop in up to 93 percent of patients after abdominal and pelvic surgeries. These sheets of fibrous scar tissue form and adhere to internal organs that aren't normally connected with equal frequency after both laparotomies and laparoscopies.
