['Preoperative anorectal physiology studies have become part of the standard evaluation of fecal incontinence. This study was undertaken to see whether anorectal physiology results predicted surgical outcome after anterior sphincteroplasty.', 'Between 1985 and 1994, 191 females with a mean age of 37 (range, 20-74) years underwent anterior sphincteroplasty for anal sphincter disruption. A follow-up questionnaire was sent to all patients, and there were 158 respondents (83 percent). Mean follow-up was 43 (range, 6-120) months. Obstetric injuries accounted for incontinence in 91 percent of the 158 patients who responded to the questionnaire. Mean duration of incontinence was 4.2 years (range, 3 months-51 years) before surgery. Preoperatively, patients were incontinent to solid stool (53 percent), liquid stool (33 percent), gas (3 percent), and unspecified (11 percent).', 'Subjectively, the results were as follows: 129 patients (82 percent) improved, 17 (11 percent) were initially improved but subsequently deteriorated, 7 (4 percent) were unchanged, and 5 (3 percent) were worse. Objectively, postoperative continence was classified as follows: excellent (normal) in 23 percent, good (incontinent to gas or minor stain) in 39 percent, fair (incontinent to stool an average of less than once per month) in 26 percent, and poor (incontinent to stool an average of greater than once per month) in 12 percent. Preoperative continence level (incontinent to solid vs. liquid stool) was predictive of postoperative continence classification. Preoperative anorectal manometry was not predictive of clinical outcome (n = 128). There was no significant difference in postoperative continence classification among patients with normal, unilaterally abnormal, and bilaterally abnormal pudendal latency (n = 89).'] Does clinical rather than laboratory assessment predict continence after anterior sphincteroplasty?
