Soap water is an alkaline liquid. Using soap water enema will stimulate the mucous membrane of perianal skin and damage the skin mucosa, which will not only cause diseases such as colitis, but also cause gastrointestinal dysfunction. Therefore, using soap water to relieve constipation has side effects.
Soap water enema can be used for preoperative preparation, because it can soften and remove feces, reduce abdominal distension and clean intestines.
Enema is a method of directly injecting a certain amount of solution into rectum and colon to stimulate peristalsis of colon and rectum to cause defecation, especially when using soap water enema, which can cause colitis, which is related to the alkalinity of soap and the toxicity of long-chain fatty acids.
In the process of soapy water enema, if improper operation damages the mucosa of digestive organs such as rectum or anal canal, it can lead to intestinal perforation to some extent, accompanied by adverse reactions of bleeding. At this time, laparoscopic surgery can be performed at the doctor's suggestion to repair the perforation.
