Fig. 2. Representation of different types of functional defecation disorder during simulated defecation with high-resolution anorectal manometry. (A) Type I, an increased intrarectal pressure with a paradoxical increase in the intra-anal pressure. (B) Type II, an inadequate intrarectal pressure with a paradoxical increase in the intra-anal pressure. (C) Type III, an adequate propulsive force along with an absent relaxation or incomplete (≤ 20%) relaxation of resting anal sphincter pressure. (D) Type IV, an inadequate increase of intrarectal pressure with absent or incomplete relaxation of anal sphincter pressure.
