AbstractWe studied the hemostatic and histopathological effects, and intra-abdominal adhesion scores of a new hemostatic agent, Ankaferd Blood Stopper (ABS), in an experimental liver injury model and compared it with regenerated oxidized cellulose. Thirty-six rats were randomly assigned to ABS, oxidized cellulose (Surgicel), and control groups (n=12, each). A wedge resection was performed on the left medial lobe of the liver. In the ABS group the liver surface was sprayed with ABS, whereas in the Surgicel group the liver was covered with double-layered oxidized cellulose. In the control group, saline solution was sprayed on the cut surface. The mean bleeding time was shorter in the ABS (23.08±6.99s) and Surgicel groups (47.91±8.21s) than in the control group (223.42±57.83s). No significant difference was found in the ABS and Surgicel groups in terms of preoperative and postoperative hematocrit (hct) values (P>0.05). Whereas there was no significant difference on day 7 (P>0.05), total adhesion score of ABS group was lower than both Surgicel (P<0.05) and control groups (P<0.01) on day 14. Liver sections from ABS group displayed more favorable histopathological changes when compared with Surgicel group on day 7 and day 14. All livers in the ABS group completed their regeneration process with minimal signs of inflammation. Our findings suggest that ABS is more effective than Surgicel and control groups in achieving hemostasis and in reducing blood loss. Apart from this, ABS causes more encouraging histopathological changes and better intra-abdominal adhesion scores in rat experimental liver trauma model.
