Postoperative Outcome after ARM

In 2001, Holschneider et al. [3] compared two groups of patients after ARM treatment: results achieved before the introduction of PSARP in the period 19621984 (n = 381) and those achieved after the introduction of Peñas technique (period 1985-1997; n = 197). Incontinence decreased during these two periods in high types of ARM from 55% to 24%, in intermediate types from 30% to 11%, and in low forms from 8% to zero. The frequency of partial continence increased in the same time interval from 32% to 56% in the high types and decreased from 60% to 47% in the intermediate forms. It remained unchanged at 25% and 21%, respectively, in the low malformations. Continence increased from 13.5% to 20% in high, 10% to 42% in intermediate, and 67% to 79% in low anomalies (Fig. 25.1).

The main postoperative problem in our last series from 1985 to 1997 of 197 children operated according to Peña was chronic constipation with overflow incontinence: 63.2% of the patients showed no constipation and had normal defecation habits, but 28.6% of the children were occasionally, and 8.3% always constipated. In other series too, chronic constipation is a well-known phenomenon. In 1992, Hedlund and Peña reported on 9 out of 30 severely constipated children and 6 with additional overflow soiling [10].

In 1995 Peña described his results in 285 children [4]. He observed chronic constipation to varying degrees in 61.4% with vestibular fistulae, 55.0% with bulbar fistulae, and 41.4% with prostatic fistulae. Soiling occurred in 0-82.6% of his patients depending on the type of the fistula. It is well known that vestibular, bulbar, and prostatic fistulae usually need more preparation to allow sacroperineal pull-through than do perineal and bladder-neck fistulae. Therefore, the possibility of damage to the extramural nerve supply to the rectum is higher in intermediate-type lesions than in low- or high-type malformations. On the other hand, in bladder-neck fistulae the development of the striated muscle complex is hypoplastic, favor

ing anal incontinence as a result of a reduced anorectal pressure barrier. Therefore, soiling was observed in 82.6% of patients with bladder-neck fistulae. Bliss et al. [11] and Chau et al. [12] found similar results (Table 25.1).

In addition, chronic constipation is also an ongoing problem after repair of low ARM. In 1997 Rintala et al. [13] found constipation in 17 out of 40 (42%) children after correction of low ARM. In addition, four patients (10%) suffered from daily soiling by overflow incontinence. Only half of the children with low ARM had age-appropriate normal bowel function.
