title: The role of overlapping sphincteroplasty in traumatic fecal incontinence.
abstract: Fecal incontinence is one of the most distressing conditions. Even there is a great variety of etiologic factors, they can be systematized in two main categories; fecal incontinence with normal and fecal incontinence with abnormal function of pelvic floor muscles. The latter is more interesting for surgeons since this category includes the great majority of surgically caused and surgically correctable fecal incontinences. Disruption of the anal sphincter caused by obstetric injury, anorectal operations or external trauma is the commonest cause of fecal incontinence. In the period 1990-1999, 53 patients with fecal incontinence caused by sphincter injury were treated on the third department for colorectal surgery, First Surgical Clinic. There were 43 females and 10 males with a mean age of 36.1 years (range 18-64). Causes of fecal incontinence were: obstetric trauma 38 patients. (71%), fistulotomy 9 (17%), war injuries 3 (6%) and nonspecific 3 (6%). The severity of incontinence was graded by Browning--Parks's classification. There were no patients in group A and B, in group C were 11 patients and in D group 37 patients. Wexner score system was also utilized preoperatively and postoperatively to determine continence function more precisely. Clinical exam, anoscopy and special investigations, such as anal manometry, EMG and defecography were carried out in all cases. Period between injury and repair was between 6 months and 20 years. Severe pudendal neuropathy was present in 17 patients. Five patients had oostomies performed at the time of injury. In three cases was present traumatic cloaca and in one case rectovaginal fistula. Overlapping sphincter repair technique was carried out in all cases. Full bowel preparation and antibiotics were prescribed. Anterior sphincteroplasty was performed in 39 cases, lateral in 7, posterior in 3 and anterior sphincteroplasty + posterior plication of puborectalis (Parks operation) in 4 patients. Protective colostomy was not performed in any case. The outcome of the procedure was considered as excellent, good, fair and poor (excellent when full control of solid and liquid stool and flatus was achieved, good when there was continence to feces but not to flatus, fair when patients could control only solid feces and poor when only partial control of solid feces was obtained). The overall functional results were as follows: Excellent in 25 patients (47.2%), good in 12 (22.7%), fair in 11 (20.7%) and poor in 5 (9.4%). Wound infection occurred in 9 (16.9%) patients, leading to disruption of sutures in three patients with consequent poor results. Two of them were reoperated. The duration of follow-up was from 5 to 60 months. We conclude that an overlapping sphincteroplasty is a method of choice in treating fecal incontinence caused by trauma. The best results are achieved with anterior sphincteroplasty. Results of posterior sphincteroplasty were disappointing. If present, pudendal neuropathy directly influences the outcome of sphincteroplasty. Manometric studies correlate with the clinical outcome.
