Postoperative abscess mimicked by Surgicel.

Laparoscopic cholecystectomy is a very common surgery in many hospitals today. Thrombogenic agents are important for visualization, especially since the gallbladder fossa is a difficult bleeding source to control. Surgicel, oxidized regenerated cellulose, is a bioabsorbable thrombogenic which given the proper clinical context can be indistinguishable from an abscess on postoperative CT scans.
