Sacral nerve stimulation is a valuable diagnostic tool in the management of anorectal and pelvic malformations

Injectable bulking treatment of persistent fecal incontinence in adult patients after anorectal malformations

BACKGROUND/PURPOSE

Injectable bulking therapy has emerged as a treatment for fecal incontinence (FI), however there are no studies including adult patients with anorectal malformations (ARM). This study aimed to evaluate non-animal stabilized hyaluronic acid with dextranomer (NASHA/Dx) for the treatment of adult ARM patients with persistent FI.

METHODS

Seven adults with ARM and incontinence to loose stool at least once weekly and without rectal or mucosal prolapse were treated with anal NASHA/Dx injection. They were evaluated preoperatively, at 6 and 18 months with a bowel function questionnaire and a 2-week bowel diary as well as FIQL and SF-36 quality of life questionnaires.

RESULTS

Before treatment, the mean number of incontinence episodes over 2 weeks was 20.7 (median 16, range 8-52). At 6 months, the corresponding figures were 5.3 (median 4, range 0-19, p = 0.018), and at 18 months the figures were 4.3 (median 2, range 1-20, p = 0.018). An improved physical function in SF-36 from 74.3 at baseline to 86.4 at 6 months was noted (p = 0.04). No serious adverse events occurred.

CONCLUSIONS

NASHA/Dx is a promising treatment option for selected adult patients with persistent FI after ARM. Longer follow up of larger patient series and studies on patients in adolescence is needed.

Sacral nerve stimulation for faecal incontinence and constipation: a European consensus statement

AIM

In Europe during the last decade sacral nerve stimulation (SNS) or sacral neuromodulation (SNM) has been used to treat faecal incontinence (FI) and constipation. Despite this, there is little consensus on baseline investigations, patient selection and operative technique. A modified Delphi process was conducted to seek consensus on the current practice of SNS/SNM for FI and constipation.

METHOD

A systematic literature search of SNS for FI and constipation was conducted using PubMed. A set of questions derived from the search and expert opinion were answered on-line on two occasions by an international panel of specialists from Europe. A 1-day face-to-face meeting of the experts finalized the discussion.

RESULTS

Three hundred and ninety-three articles were identified from the literature search, of which 147 fulfilled the inclusion criteria. Twenty-two specialists in FI and constipation from Europe participated. Agreement was achieved on 43 (86%) of 50 domains including the set-up of service, patient selection, baseline investigations, operative technique and programming of the device. The median of agreement was 95% (35-100%).

CONCLUSION

Consensus was achieved on the majority of domains of SNS/SNM for FI and constipation. This should serve as a benchmark for safe and quality practice of SNS/SNM in Europe.

Sacral neuromodulation for fecal incontinence and constipation in adult patients with anorectal malformation--a feasibility study in patients with or without sacral dysgenesis

PURPOSE

The aim of this study was to evaluate both the feasibility and effectiveness of sacral neuromodulation for fecal incontinence and constipation in adult patients who had undergone surgical repair of anorectal malformations (ARM).

METHODS

Patients with ARM with or without sacral dysgenesis who presented with fecal incontinence, constipation, or combined symptoms were treated with sacral nerve stimulation (SNS). Success of SNS was assessed by scores preoperatively and after a 3-week test period: Cleveland Clinic Incontinence Score (CCI), Surgical Working Group for Coloproctology (CACP) continence score, German version of the Fecal Incontinence Quality of Life Scale, and Cleveland Clinic Constipation Score (CCCS). The follow-up results of the patients who received a definitive pacemaker were used to evaluate the long-term effect of SNS in patients with ARM.

RESULTS

Four patients with fecal incontinence and one patient with constipation (two males, three females; median age 24 years [13; 31]) were treated with SNS between May 2012 and May 2013. Four patients had a normal sacrum; one patient had a sacral dysgenesis. Preoperatively and after the test phase, median CACP continence scores were 8 [1; 10] and 11.5 [3; 16], median CCI 14 [12; 19] and 13 [11; 17], and median Fecal Incontinence Quality of Life Scale improved in all categories. For constipation, CCCSs were 16 and 7.

CONCLUSION

Sacral neuromodulation is a feasible treatment modality for adult patients with ARM with a normally developed sacrum. Patients with sacrum dysgenesis are not suited for SNS because a definitive quadripolar electrode could not be anchored in the absence of a sacral bone.
