Anal sphincter pressures, rectal compliance and sensation in 19 women of mean age 77 (range 57-94) years were studied before and after Delorme's procedure for full-thickness rectal prolapse. No patient had significant problems with defaecation after operation. There were no significant changes in anal sphincter pressures but the volume of first rectal sensation decreased from a median of 140 ml before surgery to 65 ml after the procedure (P = 0.01) and the maximum tolerated rectal volume declined from a median of 249 ml to 120 ml (P = 0.001). Rectal compliance was reduced from a median of 142.9 ml/kPa to 12.2 ml/kPa (P = 0.002). Improved rectal sensation and lowered compliance are associated with a reduced incidence of defaecatory problems after Delorme's procedure.
对19名平均年龄77岁（范围57 - 94岁）的女性，在采用德洛姆手术治疗全层直肠脱垂前后，研究了肛门括约肌压力、直肠顺应性和感觉。术后无患者排便出现严重问题。肛门括约肌压力无显著变化，但首次直肠感觉的容量从术前的中位数140毫升降至术后的65毫升（P = 0.01），最大耐受直肠容量从中位数249毫升降至120毫升（P = 0.001）。直肠顺应性从中位数142.9毫升/千帕降至12.2毫升/千帕（P = 0.002）。直肠感觉改善和顺应性降低与德洛姆手术后排便问题发生率降低有关。
