LARGE-VOLUME INTRAOPERATIVE PERITONEAL-LAVAGE WITH AN ASSISTANT DEVICE FOR TREATMENT OF PERITONITIS CAUSED BY BLUNT TRAUMATIC RUPTURE OF THE SMALL-BOWEL

The benefits of large-volume intraoperative peritoneal lavage (IOPL), with an assistant lavage device, were evaluated retrospectively in 114 patients with peritonitis caused by blunt traumatic rupture of the sm all bowel. Postoperative complications caused by infection were a majo r problem after rupture of the small bowel (46 of 114, 39.4%). Both pr olongation of the interval between injury and laparotomy and rupture o f the lower part of the small bowel were risk factors for postoperativ e complications caused by infection. Large-volume IOPL (25.2 +/- 2.1 L ) with an assistant lavage device reduced the rate of complications ca used by infection from 30 of 58 (51.8%) to 15 of 56 (26.8%). The volum e used for IOPL was closely related to the occurrence of postoperative complications resulting from infection. No complications from infecti on occurred in patients who received lavage with of 28.3 +/- 2.7 L of saline, whereas complications occurred in those patients treated with a smaller volume of lavage fluid (18.0 +/- 2.5 L). Large-volume IOPL s hould be considered in patients with blunt rupture of the small bowel who are at risk for infection, and the assistant device for IOPL may b e useful for such treatment.
