Anorectal Abscesses and Fistulas

​Anal fistula is a recurrent infection affecting the anus and occasionally the lower rectum. It causes considerable discomfort and disability to the sufferer of this chronic condition.

In Singapore, this condition is also known as the 'rat hole'(LaoShudong) amongst the Chinese community and traditional Chinese medical practitioners. It commonly affects economically active adults in the 3rd to 5thdecades of life.
Although, anal fistula has been recognized for thousands ofyears, the treatment of the complex or recurrent anal fistula continues to challenge surgeons till today.
