Leakage of stool after perianal abscess surgery may be caused by anesthesia drugs, anal sphincter injury, anal fistula and so on.
1. The role of anesthesia drugs: due to perianal abscess surgery requires the use of anesthesia drugs, the early postoperative period due to anesthesia caused by the muscle tissue has not yet recovered, there may be anal sphincter relaxation, which is manifested in the fecal incontinence after surgery for perianal abscess, and can be restored after the anesthesia has completely disappeared.
2. Anal sphincter injury: when performing perianal abscess surgery, the anal sphincter may be damaged. At this time, the control of the anus will appear to decline, resulting in the patient can not independently defecate, the phenomenon of leakage of stool in the absence of defecation consciousness.
3. Anal fistula: most anal fistula caused by perianal abscess, cut and drain the external mouth, located in the perianal skin, forming anal fistula. Due to the recurrent episodes of anal fistula, causing widespread infection around the anorectum. There is even a decrease in the elasticity of the anorectum and the patient is unable to control bowel movements.
Leakage of stool after surgery for perianal abscess may also be caused by other reasons. If this situation still occurs after the anesthesia has worn off, it is recommended to inform the doctor in charge in time for relevant treatment.
