Resumo: 	Sodium carboxymethylcellulose (SCMC) has been effective in reducing adhesion formation and corticosteroids reduce the inflammatory process. The objective of this study was to define the intraperitoneal (ip) effects of SCMC combined with intramuscular (im) methylprednisolone on peritoneal adhesion formation and on jejunal anastomosis healing in rats. Twenty Wistar rats (200-350 g) were divided into four groups (N = 5): groups I and III (controls) 5 and 21 days of treatment before sacrifice, respectively; groups II and IV (experimental groups) 5 and 21 days of treatment, respectively. SCMC (1%) was infused into the abdominal cavity and methylprednisolone (10 mg kg-1 day-1) was injected im daily from the day before surgery for animals of groups II and IV. All rats were submitted to a jejunal anastomosis. Sections of the anastomosis were prepared for routine histopathological analysis. The abdominal adhesion of group IV was less intense when compared with group III (P&lt;0.0008). Anastomotic resistance was higher in groups II and IV when compared with groups I and III, respectively (P&lt;0.05). There was no histological difference between groups I and II (exuberant granulation tissue on the serosal surface). Group III presented little peritoneal fibrinous tissue, with numerous thick collagen fibers. Group IV presented extensive although immature young fibrous tissue with rare thick collagen fibers. Sodium carboxymethylcellulose combined with corticosteroids seemed to diminish peritoneal adhesion but did not reduce anastomotic resistance.
