OPS-Code 5-491.2:
Operations on the anus: Surgical treatment for anal fistulas: Thread drainage
You had an operation to treat an anal fistula.
The last segment of the large intestine consists of 2 sections. These 2 sections are the rectum and anal canal. The feces are collected in the rectum. The feces then move through the short anal canal to the anus. Feces are excreted through the anus.
An anal fistula is a connecting passage between the last section of the bowel and the outer skin around the anus. A thread was placed inside this connecting passage during your surgery. This is intended to allow fluid to drain from the passage.
