ObjectiveTo compare 3 kinds of topical hemostatic agents in terms of adhesive strength, control of hemorrhage, and postoperative intra-abdominal adhesions in an experimental partial nephrectomy (PN) model.MethodsA total of 27 Wistar rats were divided into 5 groups. PN was performed in 6 rats (control group) with the conventional technique, in which the lower pole of the kidney was excised and sutured after hilar control. In 5 rats, oxidized cellulose was placed over the excised part of the kidney following conventional technique. In 6 rats, the hemostatic plant extract was used without hilar control. In 5 rats, the hemostatic agent chitosan was used without hilar control. As a sham group, 5 rats underwent a laparotomy and handling of the renal pedicle without the removal of renal pole. On the tenth day after the operation, the degree of adhesions to the operated kidney were evaluated. Histopathological evaluation was also performed by a blinded pathologist.ResultsMean warm ischemia times for control and oxidized cellulose groups were 4.85 ± 0.75 and 4.28 ± 1.28 minutes, respectively (P = .662). Wound healing was excellent in all groups except in 1 rat in the chitosan group. Chitosan was associated with significantly higher intestinal and peritoneal adhesion scores, although histopathologically comparable scores were revealed.ConclusionIn our rat model, chitosan and the hemostatic plant extract were as effective as conventional suturing in achieving hemostasis even without hilar control. Warm ischemia was eliminated and PN time was significantly decreased. The use of oxidized cellulose was not associated with higher scores of adhesion, suppuration, or hematoma.Crown Copyright © 2011.
