Oxidized regenerated cellulose has become a major local surgical hemostatic biomaterial because of its ease of use, favorable biocompatibility, bactericidal activity and bioabsorption characteristics. Additional clinical indications of oxidized regenerated cellulose include wound repair and tissue reconstruction. Sometimes, some unusual adverse events are described. Studies report cases of minor postoperative complications as nidus of infection or allergic reaction mainly presenting as acute dermatitis, eczema and sieroma. Also, rare and serious cases of foreign body reaction or impingement on nerve, due to not optimal bioabsorption, are showed in various surgical sites. Thus, on the one hand, patients should be informed by their clinicians of the possibility of these low incidence postoperative complications when considering preparations made of cellulose derivatives; and the clinicians should clearly indicate use of this biomaterial in the surgical procedure report so that radiologists may appropriately interpret any unusual findings potentially associated with this biomaterial use and thus avoid misdiagnosis and undue alarm in the follow-up of patients. On the other hand, the biomedical carbohydrate scientist must consider effective experimental design that substantially addresses the clinical adverse events associated with carbohydrate polymer use. Optimal development of carbohydrates for clinical use depends on excellent clinician/biomedical scientist communication.
