ABSTRACT
AIM: Internal rectal prolapse is recognized as an aetiological factor in faecal incontinence. Patients found to have a high-grade internal rectal prolapse on routine proctography are offered a laparoscopic ventral rectopexy after failed maximum medical therapy. Despite adequate anatomical repair, faecal incontinence persists in a number of patients. The aim of this study was to evaluate the outcome of sacral neuromodulation in this group of patients. METHOD: Between August 2009 and January 2012, 52 patients who underwent a laparoscopic ventral rectopexy for faecal incontinence associated with high-grade internal rectal prolapse had persistent symptoms of faecal incontinence and were offered sacral neuromodulation. Symptoms were evaluated before and after the procedure using the Fecal Incontinence Severity Index (FISI) and the Gastrointestinal Quality of Life Index (GIQLI). RESULTS: Temporary test stimulation was successful in 47 (94%) of the patients who then underwent implantation of a permanent pulse generator. The median FISI score 1 year after sacral neuromodulation was lower than the median score before [34 (28-59) vs. 19 (0-49); P < 0.01], indicating a significant improvement in faecal continence. Quality of life (GIQLI) was significantly better after starting sacral neuromodulation [78 (31-107) vs. 96 (55-129); P < 0.01]. CONCLUSION: Patients may benefit from sacral neuromodulation for persisting faecal incontinence after laparoscopic ventral rectopexy.

BACKGROUND: Faecal incontinence is a multifactorial disorder, with multiple treatment options. The role of internal rectal prolapse in the aetiology of faecal incontinence is debated. Recent data has shown the importance of high-grade internal rectal prolapse in case of faecal incontinence. We aimed to determine the incidence and relevance of internal rectal prolapse in patients with faecal incontinence without an anal sphincter defect. METHODS: Patient data, collected in a prospective pelvic floor database, were assessed. All females with moderate to severe pure faecal incontinence, without obstructed defecation and sphincter muscle defects, were included. Data on defecation proctography, anorectal physiology and incontinence scores were analysed. RESULTS: Of 2082 females in the database, 174 fitted the inclusion criteria. High-grade internal rectal prolapse was found in 49% of patients and was associated predominantly with urge faecal incontinence. Passive faecal incontinence was more common in low-grade compared to high-grade internal rectal prolapse patients. Maximum resting pressure was lower in older patients and in patients with high-grade compared to low-grade internal rectal prolapse. Internal rectal prolapse grade was not significantly correlated with faecal incontinence severity score. CONCLUSION: High-grade internal rectal prolapse is common in female patients suffering particularly urge faecal incontinence, without anal sphincter lesions. Defecation proctography should be routine in the work up of faecal incontinence.

BACKGROUND: Prior to implantation of an expensive sacral nerve stimulator, a 'screening phase' is undertaken. This report examines the feasibility of temporary sacral neuromodulation under local anaesthesia in an outpatient setting. We report on our technique, results and patient satisfaction. METHODS: Percutaneous nerve evaluation was performed in 184 patients using a new set of reference points and local anaesthesia to guide insertion of a test wire without the need for fluoroscopy in an outpatient setting. Three bony landmarks were used: tip of the coccyx, sacro-coccygeal joint and posterior superior iliac spine. The technical success was defined as stimulation in the perineal/anal area at amperages <6 mAmp. A consecutive cohort of 24 patients was asked to grade their pain and satisfaction regarding the procedure. RESULTS: Successful placement of the test wire was accomplished in 171 patients (93 %). Twelve patients required placement under fluoroscopy due to lack of sensation during stimulation (N = 7) procedural pain (N = 4) or failure to identify S3 or S4 (N = 2). There were two lead infections, one lead dislocation and one lead fracture. 22 of 24 patients (92 %) would recommend the procedure under local anaesthesia to other patients. CONCLUSIONS: Temporary sacral neuromodulation can be reliably performed in a more practical, less expensive outpatient setting under local anaesthesia without adversely influencing test outcome.
