It can have a distressing impact and restriction on quality of life. Obstetric-related fecal incontinence may occur early after childbirth. Previous obstetric injury is a major cause of fecal incontinence in older women.\n\nWhen conservative treatment fails, surgery may be an option. Both sacral nerve modulation and anal bulking injections is minimal invasive surgical alternatives. Step one in SNM is a trial period of temporary stimulation. If the test is successful, the patient can have an implantable stimulator (step 2). Transanal submucosal bulking injection of collagen is also a possible treatment option and can be an effective treatment for faecal incontinence.\n\nThe purpose of this study is to compare the efficacy of sacral nerve stimulation to anal bulking injections in women with fecal incontinence after obstetric sphincter injuries (OASIS), through a multicenter blinded, randomized controlled trial.', 'detailedDescription': 'Obstetric anal sphincter injuries (OASIS) is the most common cause of fecal incontinence (FI) in women. Obstetric-related FI may occur early after childbirth. Previous obstetric injury is also a major cause of FI in older women, and risk of FI increases with time and further childbirths. FI is involuntary loss of solid or liquid stool. Symptoms range from fecal urgency, soiling, to daily passive or urge fecal incontinence. FI is a stigmatizing condition. It can have a distressing impact and restriction on quality of life, including isolation and depression.\n\nTears during delivery is classified (Sultan) as first degree tears including vaginal epithelium, second degree tears into the perineal muscle, third degree involving the anal sphincter complex and fourth degree including sphincter complex and anorectal epithelium. OASIS includes third and fourth degrees tears.\n\nFirst line of therapy of FI is conservative treatment including drug therapy and "biofeedback". If conservative treatment fails, surgery may be an option. Traditionally elective secondary sphincter repair has been performed at least once. Sphincter repair may improve symptoms in short time, but efficacy deteriorates with time.\n\nOther minimal invasive surgical alternatives includes sacral nerve modulation (SNM) and anal bulking injection. Sacral nerve modulation involves stimulating the sacral nerves, usually S3 or S4. Step one is a trial period of temporary stimulation (PNE test). If the test is successful, the patient can have an implantable stimulator (step 2) to modulate sacral nerve function. SNM is also beneficial for treating FI after OASIS, and SNM is a alternative to secondary sphincter repair. SNM should possibly be preferred second line treatment also after sphincter tears related FI. Transanal submucosal bulking injection of collagen is also a possible treatment option and can be an effective treatment for both anal and fecal incontinence.\n\nThe purpose of this study is to compare the efficacy of sacral nerve modulation to anal bulking injections in women with fecal incontinence after OASIS through a Scandinavian multicenter single-blinded, randomized controlled trial.\n\nTo answer the research question, we will include 66-86 women with FI after OASIS. Sphincter defects are classified using three dimensional endoanal ultrasonography. Pelvic floor function including FI is registered using validated questionnaires. All women eligible for inclusion is PNE-tested for three weeks. The purpose of this cohort analysis, is to examine the possible effect of SNM in women with sphincter defects, and the hypothesis is that there is no relation between sphincter defect classified using tree dimensional ultrasound and efficacy of SNM.\n\nWomen with more than 50 % symptom reduction during PNE test (positive PNE test), is further randomized and allocated 1:1 into one of two arms with 28 participants. One group is allocated to implantation of permanent impulse generator, Interstim II-3058 and the other group is allocated to anal sub mucosal bulking injection of collagen, Permacol. The purpose of this study is to compare the efficacy of SNM to anal bulking injection. The hypothesis is that SNM provides a mean change in improvement in St Marks Incontinence score of more than 4 compared to the anal bulking group. This study is designed as a multicenter single-blinded, randomized controlled trial.\n\nWomen with less than 50 % symptom reduction (15-28, negative PNE test), is treated in a third arm with anal bulking injection. The purpose of this cohort study, is to examine the efficacy of anal bulking injection in women suffering from FI after sphincter tears, excluded from further treatment with SNM.'}, 'eligibilityModule': {'sex': 'FEMALE', 'stdAges': ['ADULT', 'OLDER_ADULT'], 'minimumAge': '18 Years', 'healthyVolunteers': False, 'eligibilityCriteria': 'Inclusion Criteria:\n\n* fecal incontinence after OASIS\n* St Marks score \\> 8\n* failure of conservative treatment\n\nExclusion Criteria:\n\n* pregnancy\n* immunosuppressed\n* former major pelvic surgery or irradiation\n* Rectal prolapse\n* complex fistula\n* IBD\n* Lateral sphincterotomy'}, 'identificationModule': {'nctId': 'NCT01528995', 'acronym': 'KISS', 'briefTitle': 'Treatment of Fecal Incontinence After Obstetric Anal Sphincter Injuries', 'organization': {'class': 'OTHER', 'fullName': 'University Hospital of North Norway'}, 'officialTitle': 'A Blinded Randomized Controlled Clinical Trial Comparing Sacral Nerve Modulation and Anal Bulking Injections as Treatment for Fecal Incontinence After Obstetric Anal Sphincter Injuries (OASIS).', 'orgStudyIdInfo': {'id': '2011/|1300/REKnord'}}, 'armsInterventionsModule': {'armGroups': [{'type': 'ACTIVE_COMPARATOR', 'label': 'sacral nerve modulation', 'description': 'Implantation of Interstim II-3058 impulse generator after positive PNE test.
