Questions about surgery my dad had

My dad went in this morning for gall bladder and exploratory abdominal surgery. He has Hx of prostate and colon cancer and has had sx for both. Anyway, the doc attempted to do the surgery laproscopically and ended up having to do an open incision because the adhesions were so bad in the abdomen, and he also had to do a small bowel resection r/t intussuception. Anyway, my mom said they put something around the areas where they had removed the adhesions and it would prevent regrowth of the adhesions, then be absorbed by his body. Any idea what that would be?

Sorry for the lengthy background for such a short question! Thanks for any info you have!
