RESUMO
BACKGROUND The incidence of surgical complications after kidney transplantation ranges from 10-25%. The purpose of this study was to evaluate if the application of fibrin glue as a preventive agent reduces surgical morbidity after a living-related-donor kidney transplantation. MATERIAL AND METHODS A controlled clinical trial involving 78 recipients randomly assigned to receive fibrin glue and 79 in the control group without the application of fibrin glue. Patients were followed for six months after surgery. RESULTS The average ages were 24.8±9.4 and 27.4±11.3 years in the control and study groups, respectively (p=0.11). Individual morbidities, such as urologic, lymphatic, vascular, and wound complications, were not statistically different between groups; however, the total number of surgical complications observed were in five patients in the study group and 16 patients in the control group. This difference was statistically significant (p<0.01, relative risk 0.44, 95% CI 0.20-0.97). There was no mortality or adverse reaction to fibrin glue. One kidney graft was lost because of uncontrollable bleeding secondary to tearing of the renal capsule. The incidence of early medical complications was similar between groups. CONCLUSIONS Applications of the biological adhesive reduced the incidence of surgical complications.
RESUMO
BACKGROUND: The colon is the organ most commonly used for esophageal reconstruction after severe caustic injury. Complications of cervical anastomosis are very common. Fibrin sealant may reduce the incidence of complications in this high-risk anastomosis. The purpose of the present study was to assess the role of fibrin glue in the prevention of leakage and stricture at cervical coloesophageal anastomoses in children treated with esophageal reconstruction after caustic injury. METHODS: This was a case-control study of children with caustic esophageal injury treated surgically with esophageal reconstruction over a 10-year period. In the study group 3-4 ml of fibrin glue was placed over the anastomosis. The following variables were assessed: age, sex, weight, leakage or stricture at the cervical anastomosis, morbidity, and mortality. RESULTS: The study group included 14 children, and the control group included 24 children. There were no differences in the distributions of sex, age, anthropometric variables, or preoperative laboratory test results. All children underwent esophageal replacement with colon substitution through the retrosternal space. Dehiscence and leakage at the cervical anastomosis were observed in 50% of children in the control group and 28.5% of children in the study group (P = 0.17). Strictures were observed in 7.15% of the study group and 20.8% of the control group, and 5 and 17 children, respectively, developed cervical complications (P = 0.03). There were no differences in major complications, and mortality was similar in the two groups (P = 0.60). CONCLUSIONS: Fibrin glue, when used as a sealant for cervical coloesophageal anastomosis, can reduce the risk of leakage and stricture.
