Table 3 Comparison of defecographic and anal manometric findings between pre- and post-treatment of TAR in rectocele

From: Changes in anorectal physiology following injection sclerotherapy using aluminum potassium sulfate and tannic acid versus transanal repair in patients with symptomatic rectocele; a retrospective cohort study

TAR Pre-treatment Post-treatment P value
Defecography, mean (SD)
 Anorectal angle (°)
  Resting 97.67 (3.78) 99.22 (5.06) 0.229
  Squeezing 91.79 (3.65) 91.76 (3.84) 0.979
  Push 106.10 (5.94) 112.21 (4.92) < 0.001
 Perineal descent (cm) 1.58 (0.23) 2.43 (0.38) < 0.001
 Rectocele size (cm) 7.78 (1.00) 2.67 (0.69) < 0.001
Anorectal manometry, mean (SD)
 MRP (mmHg) 20.18 (2.90) 21.93 (3.54) 0.049
 MSP (mmHg) 87.87 (11.45) 94.23 (11.31) < 0.001
 Rectal sensation (mL)
  ST 85.67 (11.25) 78.06 (12.02) 0.001
  EDU 157.86 (22.54) 109.19 (24.20) < 0.001
  MTV 197.52 (31.35) 142.22 (23.83) < 0.001
  1. Data are expressed as absolute mean (standard deviation)
  2. TAR transanal rectocele repair, SD standard deviation, MRP mean resting pressure, MSP maximal squeezing pressure, ST sensory threshold, EDU earliest defecation urge, MTV maximal tolerable volume
