PURPOSE: The aim of this study is to compare the results of different operating techniques and suture materials for pyloric exclusion procedures. METHODS: The study was conducted on a sample of 125 rats. Transgastric pyloric exclusions with gastrojejunostomy were performed on the first 50 rats, which were divided into two groups each of 25: a resorbable (polyglactin) suture material was used in the first group and a nonresorbable (silk) material was used in the second group. External pyloric exclusion with a gastrojejunostomy were performed in a subsequent group consisting of 50 rats, again divided into two subgroups of 25 each with an absorbable (polyglactin) suture material used in one and a nonabsorbable (silk) material used in the other. For the last 25 rats external pyloric exclusion with a gastrojejunostomy were performed and a nonresorbable (polypropylene) material was used. RESULTS: The ratio of pyloric reopening was higher in the transgastric group than the external exclusion group on the 14th day (P = 0.01). The external pyloric exclusion group with polypropylene suture material had the lowest ratio of pyloric reopening. CONCLUSION: The external pyloric exclusion technique with nonresorbable (preferably polypropylene) suture material was therefore found to provide a higher pyloric closure incidence on the 14th day, which is the necessary duration period for healing in duodenal injuries.
