Abstract
The physiological abnormalities in piles before and after surgery were studied by an ambulatory prolonged anorectal manometric technique. Eighteen consecutive patients (12 men, 6 women; mean age 43.6 [standard error of mean, 3.3] years) with 3 prolapsed irreducible piles were prospectively recruited. Haemorrhoidectomy was performed with excision of 3 piles. The anal and rectal pressures were monitored before and at a mean 7.8 (1.5) weeks after surgery when the wounds had healed, for a mean period of 361.3 (47.8) min. The maximum anal pressures dropped significantly from a mean 325 (15.5) mmHg before to 213 (24.9) mmHg after surgery (P < 0.05). Ultraslow wave activity was clearly identified in 11 of 18 patients (61%) before surgery, but not found on post operative studies. The maximum rectal pressures were also significantly reduced after surgery (196.8 [23.2] mmHg before, 75.5 [10.6] mmHg after; P < 0.05). These findings help to confirm that haemorrhoidectomy leads to changes in the anorectal physiological findings.
