Fecal leakage after open lateral internal anal sphincterotomy for chronic fissure is common, but underreported. The aim of this study was to prospectively assess the physiologic and morphologic effects sphincterotomy, comparing continent incontinent patients surgery. This group further compared with an unselected presenting incontinence hemorrhoidectomy.Between January 1997 June 1999, 23 were followed up through conventional vector volume anorectal manometry, parametric assessment rectoanal inhibitory reflex, endoanal magnetic resonance imaging. Fourteen 9 postoperative cases, referred hemorrhoidectomy, 33 healthy volunteers without disease.Significant differences noted between postsphincterotomy cases all resting parameters some squeeze parameters. Although there a significant reduction in high pressure zone length at rest, no groups. There increase sphincter asymmetry 6.7 percent (+/- 3.5 percent) decrease 2.8 3.2 cases. Significant posthemorrhoidectomy patients, higher latter group. area under curve smaller when cohorts over distal intermediate zones rest reduced latency inhibition. difference images site case had evidence sphincteric damage.There are complex physiology undergoing who become those maintain continence. These changes not reflected detectable differences. It unknown whether these predict long-term incontinence, it suggested that minor surgery necessarily related either preexisting defect or inadvertent intraoperative injury.
