LONG-TERM RESULTS OF POSTANAL REPAIR (PAR KS) - AN ELECTROMYOGRAPHIC,MANOMETRIC AND RADIOLOGICAL STUDY 31 PATIENTS

This study was carried out to document the long-term results of postan al repair for idiopathic faecal incontinence. Thirty-one patients (mea n age 65.6 years) were followed up for 2-7.5 years (median 4.2 years). Continence was improved in 16 (52%) patients, only 2 (6%) of whom reg ained normal continence. No significant change in resting anal pressur e, maximum squeeze pressure, pelvic descent or anorectal angle was see n postoperatively. The electromyographical signs, e.g. duration and am plitude of action potentials, average amplitude, and integrals of the curves did not change significantly after the operation. The mean righ t pudendal nerve terminal motor latency (PNTML) increased from 2.38 ms before to 2.59 ms after surgery (P>0.05). No significant change in th e continence and defaecation index was seen postoperatively.
