peritoneal lavage
The irrigation of the peritoneal cavity with saline solution during laparoscopic surgery for cleansing or diagnostic purposes.
Full Definition
Peritoneal lavage in laparoscopic surgery involves the instillation and aspiration of sterile saline or other irrigation solutions within the peritoneal cavity to remove debris, blood, infected material, or to dilute contamination. This technique is commonly used in cases of peritonitis, appendiceal perforation, or gallbladder perforation to reduce bacterial load and remove particulate matter. The procedure involves systematic irrigation of dependent areas of the pelvis and paracolic gutters, followed by complete aspiration of fluid. Copious irrigation may be performed with warmed saline to prevent hypothermia during prolonged procedures.
Usage
Usage note: Hyphenate when used as compound adjective (peritoneal-lavage technique).
