Abstract
Background: Abdominal lavage is a common surgical practice, but few studies have been conducted to assess its efficacy at removing cells from the abdominal cavity, particularly during laparoscopic surgery. Methods: After three 12-mm trocars were inserted into six female 30-kg pigs at the umbilicus left and right iliac fossae, the abdomen was insufflated with carbon dioxide. The pelvis of each pigs was injected with 6 million radiolabeled LIM 1215 cells. Then the abdominal cavity was irrigated with either 500 ml 0.9% saline, 500 ml 10% betadine solution, or 1 L 0.9% saline. A maximum of 5 L of solution was used for each animal. The lavage fluid was suctioned into separate containers after each aliquot, and each container was measured for radioactivity. Results: Significantly greater numbers of cells were removed by lavage by the first to third lavage cycle; however, after four lavage cycles, relatively few cells were removed by each further cycle. No difference was observed between 500-ml and 1-L aliquots. Additionally, the mechanical efficacy of 0.9% saline and 10% betadine solution appeared similar. Conclusion: These findings suggest that optimal lavage consists of four irrigation/suction cycles utilizing 500-ml aliquots.
