Chapter 33: Anal Dilation With Hagar Dilators (continued)

Mouen A . Khashab, MD

Hagar dilators are incremental metal sounds that are used to gradually dilate strictures of the anal canal (after ileoanal pull-through or other surgical or functional stricture of the anus). This may be done in conjunction with flexible sigmoidoscopy or by itself after digital rectal exam. Figure 33-1. Hagar dilators.    If sedation is used, monitoring is the same as for diagnostic colonoscopy.    If sedation is not used, no intraprocedure monitoring is necessary.
