Abstract
Background
Many studies have evaluated the use of grafts in the reconstruction of abdominal wall defects. In this study, the effects resulting from the presence or absence of the omentum were evaluated in the setting of infection or serosal defects in the formation of adhesions in abdominal closures using mesh grafts.
Methods
For this study, 60 Wistar albino rats were divided into six groups. A circular 3.79-cm2 fascioperitoneal defect was created. After group-specific procedures, defects were reconstructed using polypropylene mesh grafts. In group C (control group), only a mesh graft recontruction was performed, whereas group O (O for omentectomy) underwent an omentectomy plus mesh closure. In group SD (serosal defect group), the cecum was abrased with a brush before mesh closure. Group SDO underwent cecal abrasion plus an omentectomy. In group I (infection group), the intraabdominal space was filled with 1 ml of solution containing 100,000 colony-forming units (CFUs) of Escherichia coli per milliliter. Group IO received the same same amount of E. coli solution plus an omentectomy before mesh closure. After 28 days, the groups were evaluated by intraabdominal and blood cultures, grading of intraabdominal adhesions, graft–organ adhesions, proportion of adhesions to graft size, and histopathologic studies. The results were statistically evaluated using one-way variant analysis and Scheffe’s and Fisher’s definite chi-square tests.
Results
For the groups in which the greater omentum was preserved, intestinal adhesions to the graft surface were less frequently observed, especially in cases with intraabdominal infections and serosal defects (p < 0.05).
Conclusions
Preservation of the greater omentum reduces the formation of intestinal adhesions, especially in cases with underlying infections and serosal defects in abdominal closures using mesh grafts. This could be beneficial in related clinical situations in lowering the rate of intestinal fistulas, erosions, and obstructions that can be attributed to the formation of adhesions.
