BackgroundIn the current study, we aimed to investigate the influences of pentoxifylline, which increases the flexibility, deformability and viscosity of the erythrocytes while reducing the aggregation abilities of the platelets, and vinpocetine, which has neuroprotective and antioxidant effects, on healing of colonic anastomoses.MethodsWe used 30 Albino Wistar rats. Subjects were divided into three groups of 10 rats each. Colonic ischemia was established in all the groups. Following colonic transection, anastomosis was performed. Group A received intraperitoneal saline, whereas Group B and Group C received pentoxifylline and vinpocetine, respectively. The subjects were sacrificed on the postoperative 5th day by ether anesthesia, and their colonic bursting pressures were measured. The anastomotic area was excised for hydroxyproline assay and histopathologic examination.ResultsAccording to intergroup comparisons, colonic bursting pressure was found to be higher in the treatment groups than in the control group; however, the difference was not statistically significant. Intergroup comparisons regarding tissue hydroxyproline levels showed statistically significant differences between Groups A and B, Groups A and C and Groups B and C.ConclusionSimilar to pentoxifylline, vinpocetine was also shown to have a beneficial effect over ischemic colon anastomoses.
