PURPOSE:To analyze the effectiveness of bacterial cellulose hydrogel as a barrier in preventing postoperative peritoneal adhesion in rat model.METHODS:Experimental study with 45 Wistar rats (Rattus norvegicus) that were divided into three groups for the following treatments: A. Saline, B. Oxidized Regenerated Cellulose (ORC) barrier, and C Bacterial Cellulose Hydrogel (BCH) barrier. After 45 days of the surgery the adhesions were classified and graded according to the qualitative score. The histological parameters were evaluated using a modified semi-quantitative scale to rate the extent of fibrosis, inflammatory reaction and vascular proliferation.RESULTS:Compared with the saline group (A), the treatments with ORC barrier (B) and BHC barrier (C) resulted in a smaller number of adhesions (p=0.019 and p=0.003 on Fisher's exact test, respectively). Data from inflammation and neovascularization showed no statistically significant difference between the groups BHC and ORC (p=0.426 and 0.446 on chi-square test, respectively).CONCLUSION: Bacterial cellulose hydrogel is effective as a bio-re-absorbable barrier for preventing postoperative peritoneal adhesions.
