title: Effectiveness of treatment to prevent adhesions after abdominal surgery: an experimental evaluation in rats.
abstract: This study was conducted to determine the probability of adhesion formation with certain materials after abdominopelvic surgery, and to assess the effectiveness of adhesion-preventing agents. The study included 2 phases. In the first phase of the study, 50 rats that had been divided into 5 groups were examined. Group 1 served as the control group. In group 2, 2 mL blood was taken from the femoral vein of the rat; in group 3, 0.0625 g talcum powder was mixed with 2 mL saline; in group 4, 2 mL ileal content was identified; and in group 5, 2 mL cecal content had spilled into the peritoneum. In the second phase of the study, 50 rats that had been divided into 5 groups were examined. Ileal content was the leading cause of intraperitoneal adhesions in the first phase; in the second phase, in group 1, 2 mL ileal content and 5 mL povidone-iodine (10%) were used; in group 2, 2 mL ileal content and 5000 units aprotinin were mixed with 5 mL saline; in group 3, 2 mL ileal content and 25 IU heparin (5000 IU/L) were mixed with 5 mL saline; in group 4, 2 mL ileal content and 5 mL 32% dextran 70 were combined; and in group 5, 2 mL ileal content was used together with 5 mL Ringer's lactate. On postoperative day 14, the rats were killed with the use of high-dose intramuscular ketamine, and necropsies were performed on all rats. Adhesions were most often established because of ileal and cecal contents. Blood and talcum powder produced less adhesion formation. Heparin and 32% dextran 70 were significantly more effective at preventing adhesion formation due to ileal contents. Intraperitoneal heparin and 32% dextran 70 may be particularly valuable for the prevention of adhesions due to intestinal content in cases with no contraindications.
