Colonic lavage is a medical procedure that involves the introduction of a significant volume of filtered water into the colon through a sterile catheter that is inserted into the rectum. This process utilizes gravity to facilitate the flow of water, as the reservoir containing the water is positioned above the patient. The gravitational force allows for a gentle and continuous infusion of water into the colon, which helps to flush out its contents. Specifically, this procedure utilizes 35 or more liters of water, ensuring that the entire colon is adequately filled and cleansed. The primary purpose of colonic lavage is to alleviate chronic constipation, particularly in cases where patients have not responded to conventional treatments such as stool softeners or other pharmacological interventions. By inducing defecation through this method, healthcare providers aim to relieve symptoms associated with severe constipation and improve overall bowel function.
