The aim of our study was to test the hypothesis that elderly women undergoing tension-free vaginal tape surgery (TVT) will have a better quality of life (QOL) and satisfaction compared to non-treated women despite age- and technique-related potential morbidity.
                This multicenter, prospective, randomized, controlled trial enrolled a total of 69 women aged over 70 years who initially consented to be randomized to either undergo immediate TVT surgery or to wait for 6 months before submitting to the same surgery (control group). The main outcomes measured at every visit (pre-randomization, 8-12 weeks and 6 months) consisted of the Incontinence-Quality of Life (I-QOL) Questionnaire, the Patient Satisfaction Questionnaire and the Urinary Problems Self-assessment Questionnaire, among others.
                The analysis included 31 patients in the immediate surgery group and 27 subjects in the control group. Peri-operative complications in the immediate surgery group were bladder perforation (22.6%), urinary retention (12.9%), urinary tract infection (3.2%) and de novo urgency (3.2%). At 6 months, the mean I-QOL scores for the TVT and control groups were respectively 96.5 +/- 15.5 and 61.6 +/- 19.8 (P < 0.0001); mean Patient Satisfaction scores were respectively 8.0 +/- 2.7 and 2.0 +/- 2.4 (P < 0.0001); and mean Urinary Problems scores were respectively 4.5 +/- 4.3 and 11.6 +/- 3.5 (P < 0.0001).
                At 6 months post-randomization, the group of elderly women who underwent immediate TVT surgery showed a significant improvement in QOL, patient satisfaction and less urinary problems compared to the group of women waiting for the same surgery.
                (c) 2007 Wiley-Liss, Inc. In a prospective randomized trial clinical results of orthograde bowel lavage alone (group I) versus combined bowel lavage and parenteral antibiotic prophylaxis with 4 gm Cefoxitin (group II) in two separate dosages (perioperative short-term-prophylaxis) are compared with regard to the reduction of septic complications after colorectal surgery. Septic wound complications were 11/27 = 41% in group I and 2/30 = 7% in group II. The rate of anastomotic leakages was significantly different in the two groups (5/27 in group I, 0 in group II). The monetary costs for given antibiotics and the duration of hospitalization were less in group II. Orthograde bowel lavage alone proved to be of no effect in reducing the rate of septic complications when used without antibiotic perioperative short-term-prophylaxis and therefore cannot be recommended to be used solely. The present study was designed to evaluate functional outcome of perineal repair with and without levatorplasty versus transanal repair of rectocele in obstructed defecation.
                A total of 48 multiparous women with obstructed defecation caused by a rectocele were randomly allocated to three groups: transperineal repair with levatorplasty (TPR-LP; n = 16); transperineal repair without levatorplasty (TPR; n = 16); and transanal repair (TAR; n = 16). The study included defecographic assessment, anal manometry, symptom improvement, sexual function, and score on a function questionnaire. Assessments were done preoperatively and 6 months postoperatively.
                Defecography showed significant reduction in size of rectocele in all groups. Constipation improved significantly in both groups with transperineal repair but not in the group with transanal repair. Significant reductions in mean anal resting pressure, maximum reflex volume, and urge-to-defecate volume were observed only with the transperineal approach (with and without levatorplasty). Functional score improved significantly in the transperineal groups (with levatorplasty, P < 0.001; without levatorplasty, P < 0.01), but not in the transanal group (P = 0.142). Levatorplasty added to transperineal repair significantly improved the overall functional score compared with transperineal repair alone (P < 0.01) and transanal repair TAR (P < 0.001).
                Rectocele repair appears to improve anorectal function by improving rectal urge sensitivity. Transperineal repair of rectocele is superior to transanal repair in both structural and functional outcome. Levatorplasty improves functional outcome, but potential effects on dyspareunia should be discussed with the patient. Our purpose was to determine whether a vaginal or abdominal approach is more effective in correcting uterovaginal prolapse.
                Eighty-eight women with cervical prolapse to or beyond the hymen or with vaginal vault inversion > 50% of its length and anterior vaginal wall descent to or beyond the hymen were randomized to a vaginal versus abdominal surgical approach. Forty-eight women underwent a vaginal approach with bilateral sacrospinous vault suspension and paravaginal repair, and 40 women underwent an abdominal approach with colposacral suspension and paravaginal repair. Ancillary procedures were performed as indicated. Detailed pelvic examination was performed postoperatively by the nonsurgeon coauthor yearly up to 5 years. The women were examined while standing during maximum strain. Surgery was classified as optimally effective if the woman remained asymptomatic, the vaginal apex was supported above the levator plate, and no protrusion of any vaginal tissue beyond the hymen occurred. Surgical effectiveness was considered unsatisfactory if the woman was symptomatic, the apex descended > 50% of its length, or the vaginal wall protruded beyond the hymen.
                Eighty women (vaginal 42, abdominal 38) were available for evaluation at 1 to 5.5 years (mean 2.5 years). The groups were similar in age, weight, parity, and estrogen status, and 56% had undergone prior pelvic surgery. There was no significant difference between the groups in morbidity, complications, hemoglobin change, dyspareunia, pain, or hospital stay. The vaginal group had longer catheter use, more urinary tract infections, more incontinence, decreased operative time, and lower hospital charge. Surgical effectiveness was optimal in 29% of the vaginal group and 58% of the abdominal group and was unsatisfactory leading to reoperation in 33% of the vaginal group and 16% of the abdominal group. The reoperations included procedures for recurrent incontinence in 12% of the vaginal and 2% of the abdominal groups. The relative risk of optimal effectiveness by the abdominal route is 2.03 (95% confidence interval 1.22 to 9.83), and the relative risk of unsatisfactory outcome using the vaginal route is 2.11 (95% confidence interval 0.90 to 4.94).
                Reconstructive pelvic surgery for correction of significant pelvic support defects was more effective with an abdominal approach. This study was designed to compare outcomes of transanal and vaginal techniques for rectocele repair.
                Thirty females with symptomatic rectocele were enrolled in a prospective, randomized study. Fifteen underwent transanal rectoceleplasty, the other 15 underwent vaginal posterior colporrhaphy. Patients were assessed by clinical interview and examination, defecography, colon transit study, and anorectal manometry before randomization and 12 months postoperatively. Patients with compromised anal sphincter function or other symptomatic prolapse were excluded.
                The study groups were comparable in terms of demographic factors and rectocelerelated symptoms and signs. Eleven (73 percent) patients in the vaginal group and 10 (66 percent) in the transanal group digitally assisted rectal emptying preoperatively. The mean depth of the rectocele was 6.0 +/- 1.6 cm vs. 5.6 +/- 1.8 cm (P = 0.53) in the respective groups. At follow-up, 14 (93 percent) patients in the vaginal group and 11 (73 percent) in the transanal group reported improvement in symptoms (P = 0.08). Need to digitally assist rectal emptying decreased significantly in both groups, to one (7 percent) for the vaginal group and four (27 percent) for the transanal group (P = 0.17 between groups). The respective recurrence rates of rectocele were one (7 percent) vs. six (40 percent) (P = 0.04), and enterocele rates were zero vs. four (P = 0.05). In the vaginal group defecography showed a significant decrease in rectocele depth whereas in the transanal group the difference did not reach statistical significance. None of the patients reported de novo dyspareunia, but 27 percent reported improvement.
                Patients' symptoms were significantly alleviated by both operative techniques. The transanal technique was associated with more clinically diagnosed recurrences of rectocele and/or enterocele. Adverse effects on sexual life were avoided by use of both techniques. The purpose of this study was to compare 2 anti-incontinence procedures in women who had severe genital prolapse and potential stress incontinence.
                In addition to vaginal reconstructive surgery, 50 patients with stage II or higher anterior defect and a positive stress test result with prolapse reduction received either tension-free vaginal tape or plication of the endopelvic fascia. Preoperative evaluation included history, physical examination, stress test, and urodynamic assessment. Data were analyzed with the Student t test, the Fisher's exact test, and the Wilcoxon signed-rank test.
                The median follow-up time was similar for both groups, 26 and 24 months. Subjective (96% vs 64%; P=.01) and objective (92% vs 56%; P<.01) continence rates were higher after the tension-free vaginal tape procedure. Time for the resumption of spontaneous voiding, rates of urinary retention, or de novo urge incontinence were similar in the 2 groups.
                Tension-free vaginal tape can be recommended for patients with prolapse and occult stress incontinence. To test the effectiveness of weekly postoperative pelvic floor muscle training (PFMT) versus supportive telephone contact by a urology nurse for men at 4 weeks after radical prostatectomy.
                This was a randomized controlled trial in three Canadian centers. At 4 weeks after surgery, standardized verbal and written instruction about PFMT was provided to all subjects. Randomization occurred after initial instruction. Continence was defined as 8 g or less of urine loss on a 24-hour pad test. Primary outcome was grams of urine loss on pad test; secondary outcomes were International Prostate Symptom Score (IPSS), Incontinence Impact Questionnaire (IIQ-7) score, cost, and perception of urine loss as a problem. Data were obtained at baseline (preoperatively) and at weeks 4, 8, 12, 16, and 28 and 1 year after surgery.
                A total of 216 men were enrolled; 11 were dry or withdrew at 4 weeks. Ninety-nine were randomized to the control group and 106 to the treatment group. There were no group differences at baseline for prostate-specific antigen level (mean [standard deviation] 8.4 [10.4] ng/mL; 7.6 [4.6] ng/mL), Gleason score (6.3 [0.86]), IPSS, IIQ-7 score, pad test, or voiding diary. At 8 weeks 23% of the control group and 20% of the treatment group were continent; at 12 weeks, 28% and 32%; 16 weeks, 40% and 44%; 28 weeks, 50% and 47%; and at 52 weeks, 64% and 60%, respectively. There were no significant differences between groups at any time point for the outcome variables.
                Verbal instruction and written information with telephone support seemed to be as effective as intensive PFMT. Less-intense therapy may be more cost-effective. The results of controlled-intermittent anal dilatation (CIAD) or lateral internal sphincterotomy (LIS) in the treatment of chronic anal fissures are presented.
                Forty patients who were randomized to two groups underwent CIAD or a LIS. The pre- and post-operative mean anal canal resting pressures (MACRPs) and symptoms were recorded and the results were compared.
                Two months post-operatively, 18 patients in the CIAD group and 17 patients in the LIS group had healed completely, and had no anal incontinence or other complications. The post-operative improvement in pain, bleeding, and constipation did not differ significantly between the two groups. In the CIAD and LIS groups, the pre-operative MACRPs were 89.7+/-16.5 and 87.6+/-12.3 mmHg, respectively; 2 months post-operatively, the MACRPs had significantly decreased to 76.9+/-13.7 and 78.1+/-11.3 mmHg in the CIAD and LIS groups, respectively. No statistical difference existed in the pre- or post-treatment MACRPs between the groups.
                CIAD applied with a standardized technique reduced anal canal resting pressure and provided symptomatic healing that was equivalent to a LIS. Since there were no findings of incontinence, or situations which resulted in sphincter damage, we conclude that CIAD is suitable for patients with chronic anal fissures because it is less invasive than LIS, with equivalent efficacy and safety. In addition, the CIAD method may be an alternative procedure in older and multiparous women who has a higher risk of incontinence. To determine under controlled conditions whether there are significant differences in the duration of hospitalization and recovery between abdominal and vaginal hysterectomy for indications other than uterovaginal prolapse.
                In a two-center prospective, double-blind randomized trial, 36 women with dysfunctional uterine bleeding, uterine fibroids or pelvic pain scheduled for hysterectomy were randomized to abdominal or vaginal hysterectomy. The primary outcome measure was the duration of hospital stay. Secondary outcome measures included analgesic requirements and return to normal health and function.
                There were no significant differences in peri-operative patient or surgical characteristics. Vaginal hysterectomy was associated with a reduction in hospital stay compared to abdominal hysterectomy (median stay 3 days vs. 5 days, p = 0.01). In addition, patients undergoing vaginal hysterectomy had reduced analgesic requirements (mean 75.4 mg vs. 131.4 mg morphine equivalent, p = 0.002), shorter need for intravenous hydration (mean 25.3 h vs. 32.7 h, p = 0.05), and faster return of bowel action (median 3 days vs. 4 days, p = 0.002). They also returned to normal domestic activities (mean 4.6 weeks vs. 8.5 weeks, p = 0.01) and work (mean 7.0 weeks vs. 13.9 weeks, p = 0.005), and completed their recovery (mean 7.9 weeks vs. 16.9 weeks, p = 0.008) more quickly.
                Vaginal hysterectomy was associated with significant benefits in terms of reduced hospital stay and improved patient recovery. Vaginal hysterectomy should be the route of choice not only for women with genital tract prolapse but also those without. To evaluate the contribution of the anal plug to the management of fecal incontinence in children and adults.
                Effective management of fecal incontinence remains problematic. Previous studies of an anal plug have yielded conflicting results.
                A randomized controlled trial was conducted. The intervention was the Conveen anal plug (Coloplast Limited) used for 12 months. Outcomes measures included: generic measures of child health [Functional Status II-R, Child Health Questionnaire (CHQ-PF50) and Dartmouth Primary Care Cooperative Information Project Charts]; generic measures of adult health for patients and carers (the SF-36, and Patient Generated and Carer Generated indices); condition-specific measures for adults and children; qualitative interviews, bowel charts, and diaries. The main outcome measure was a condition-specific score on a 0 to 100 scale, where 0 was the most severe and 100 was the least severe incontinence.
                Thirty-one intervention and 17 control patients were recruited. Fecal incontinence was due to 1 of 3 reasons: congenital, acquired, and neurogenic. At baseline, patients managed their condition preemptively or protectively. Intervention patients used the plug as a complete management substitute or as an adjunct to existing management. The majority of intervention respondents retained the plug most of the time. There was greater improvement from baseline in mean condition-specific score in intervention group compared with control group but this difference was not statistically significant (t test P=0.053). Complete data analysis using analysis of covariance showed the mean difference between the treatment groups in condition-specific score of 9.9 (95% confidence interval-1.4, 21.1). Intention to treat analyses using imputation showed similar results. There was generally greater improvement in intervention groups subjects using other measures for children, adults, and carers.
                The anal plug is of benefit to the majority of patients. It does not suit all eligible patients with in situ plug retention being a problem for some. To compare objective and subjective outcomes after the tension-free vaginal tape procedure (TVT) with laparoscopic mesh colposuspension as a primary treatment for female stress urinary incontinence. Objective outcome measures were stress test and 48-hour pad test.
                In 6 departments of gynecology in Finland, including 4 university teaching hospitals and 2 central hospitals, 128 women with urodynamic stress incontinence were randomly allocated to 2 treatment groups. Seventy were treated with TVT and 51 by means of laparoscopic mesh colposuspension. There were 7 dropouts. Inclusion criteria were history of stress incontinence, positive stress test, and urodynamic conformation of stress incontinence. Exclusion criteria were age older than 70 years, previous incontinence surgery, more than 3 episodes of urinary tract infection within the last 2 years, coincident other gynecological surgery, body mass index more than 32 kg/m(2), urethral closure pressure less than 20 cm H(2)O, and residual volume more than 100 mL in preoperative urodynamic evaluation. Assessment took place before treatment and at 12 months postoperatively with the cough stress test, Urge Score, 48-hour pad test, King's College Health Questionnaire, Visual Analog Scale, and Urinary Incontinence Severity Score.
                When negative stress test was used as criteria for cure, 85.7% of women in the TVT group and 56.9% in the laparoscopic mesh colposuspension group were objectively cured. Subject satisfaction was significantly better after the TVT procedure than after laparoscopic mesh colposuspension.
                Treatment with TVT results in higher objective and subjective cure rates at 1 year than treatment by means of laparoscopic mesh colposuspension. Our aim was to evaluate the efficacy of polyglactin 910 mesh in preventing recurrent cystoceles and rectoceles.
                In a prospective, randomized, controlled trial, patients undergoing vaginal reconstructive surgery with cystoceles to the hymenal ring and beyond were randomly selected to undergo anterior and posterior colporrhaphy with or without polyglactin 910 mesh reinforcement. Results were evaluated preoperatively and at 2, 6, 12, and 52 weeks postoperatively.
                A total of 161 women were randomly selected for this study. One woman was excluded at the time of surgery, and 17 women were lost to follow-up. Eighty women received mesh, and 80 did not. Both groups were found to be equivalent with respect to age, parity, concomitant surgery, and menopausal and hormone replacement status. Preoperatively 49 women had a central cystocele to the hymenal ring and 111 women had cystoceles beyond the introitus; 91 women had a rectocele to the mid-vaginal plane, 31 to the hymenal ring, and 22 beyond the introitus. After 1 year, 30 (43%) of 70 subjects without mesh and 18 (25%) of 73 subjects with mesh had recurrent cystoceles beyond the mid-vaginal plane (P =.02). Eight women without mesh and 2 women with mesh had recurrent cystoceles to the hymenal ring (P =.04). No recurrent cystoceles beyond the hymenal ring occurred in either group. Multivariate logistic regression analysis showed concurrent slings to be associated with significantly fewer recurrent cystoceles (odds ratio, 0.32; P =.005), whereas the presence of mesh remained significantly predictive of fewer cystocele recurrences in this analysis. Thirteen recurrent rectoceles were noted 1 year postoperatively, with no differences between groups.
                Polyglactin 910 mesh was found to be useful in the prevention of recurrent cystoceles. Severe prolapse may mask potential genuine stress urinary incontinence in women. Some have suggested that a suspending urethropexy be performed in women who have potential genuine stress incontinence demonstrated by barrier reduction of the prolapse preoperatively. Our aim was to compare outcomes after prolapse surgery that included a formal bladder neck suspension with those operations that did not.
                This prospective randomized clinical trial assigned 32 women with bladder neck hypermobility and stage III or IV pelvic organ prolapse to receive either a needle colposuspension or bladder neck endopelvic fascia plication as part of the vaginal reconstructive surgery. Twenty-nine subjects underwent detailed clinical, anatomic, urodynamic, and quality-of-life evaluations before and 6 weeks and 6 months after surgery; 23 completed urinary diary and quality-of-life evaluations after a mean of 2.9 years.
                Needle colposuspension increased short-term complications without providing additional protection from de novo stress incontinence. Barrier testing before surgery predicted urethral sphincteric resistance after surgery; however, such testing neither predicted a patient's function after surgery nor indicated the need for a suspending urethropexy. The combination of a needle colposuspension with a sacrospinous ligament suspension predisposed to the early development of support defects of the upper anterior vaginal segment and to failure of bladder neck support.
                Preoperative barrier testing in women with severe prolapse is not useful in identifying individuals who require a suspending urethropexy. Needle colposuspension increases short-term complications, lacks durability, and may predispose to early and severe recurrent anterior prolapse when performed with a sacrospinous ligament vault suspension. In women with "idiopathic" fecal incontinence (FI), consensus guidelines recommend anal sphincter imaging and surgical repair, when feasible, of anal sphincter defects believed to cause FI. However, the relative contributions of obstetric trauma and bowel symptoms to FI in the community are unknown.
                To assess risk factors for FI during the past year, a previously validated questionnaire was mailed to an age-stratified random sample of 5,300 women residing in Olmsted County, Minnesota.
                Altogether, 2,800 women (53%) responded. The risk of fecal incontinence increased with age (odds ratio [OR] per decade 1.3, 95% CI 1.2-1.4). The risk of fecal incontinence was higher among women with rectal urgency (OR 8.3, 95% CI 4.8-14.3) whether or not they also had other bowel disturbances (i.e., constipation, diarrhea, or abdominal pain) or had a vaginal delivery with forceps or stitches (OR 9.0, 95% CI 5.6-14.4). Among women with FI, rectal urgency and age were also risk factors for symptom severity. In contrast, obstetric risk factors for anorectal trauma did not increase the risk for FI. The risk for FI was not significantly different among women with cesarean section, vaginal delivery with or without forceps or stitches, or anorectal surgery, compared with nulliparous women without any of these risk factors.
                Rectal urgency rather than obstetric injury is the main risk factor for FI in women. These observations reinforce the importance of behavioral, dietary, and pharmacological measures to ameliorate bowel disturbances before anal imaging in women with "idiopathic" FI. The object of this study was to determine the prevalence of anal incontinence among women with previous multiple pregnancy and childbirth and assess risk factors.
                A 77-item questionnaire was administered to 769 mothers of multiples. Statistical analyses included chi(2), Student t test, and logistic regression.
                Seven hundred thirty-three (95.3%) women completed the survey, 94% of them white, with a median age of 37 years. Fecal incontinence affected 10% (6.3% arose during pregnancy, 40.6% after delivery, 53.1% unrelated to childbirth). Although delivery by cesarean section only was associated with lower prevalence in univariate analysis (5.8% vs 11%, P=.02), age was the only significant covariate in multivariate regression (P=.0001). Flatal incontinence affected 25.2% (21.2% during pregnancy, 30.3% after delivery, 48.5% unrelated), increasing with age (P=.0001). Soiling affected 10%, increasing with age (P=.0001).
                Mothers of multiples reported substantial rates of fecal (10%) and flatal (25.2%) incontinence. Advancing age was the major risk factor. Delivery by cesarean section only was not significantly protective, although elective (before labor) cesarean deliveries were not separately assessed. To compare the effects of vaginal hysterectomy (combined with anterior and/or posterior colporraphy) and abdominal sacro-colpopexy (with preservation of the uterus) on urogenital function.
                Randomised trial.
                Three teaching hospitals in The Netherlands.
                Eighty-two patients undergoing surgical correction of uterine prolapse stages II-IV.
                Participating patients completed the urogenital distress inventory (UDI), before and at six weeks, six months and one year after surgery, to measure discomfort of prolapse and micturition symptoms. Domain scores of the UDI (ranging from 0 to 100, higher scores indicating more discomfort) were compared between groups at all time points. Findings at pelvic examination, number of doctor visits within the first year after surgery because of pelvic floor symptoms and performed or planned surgery of recurrent genital prolapse were also compared.
                Domain scores of the UDI at one year after surgery.
                At one year after surgery, scores on the discomfort/pain domain (mean difference 7.1, 95% confidence interval [CI] 1.1-13.2), overactive bladder domain (mean difference 8.7, 95% CI 0.5-16.9) and obstructive micturition domain (mean difference 10.3, 95% CI 0.6-20.1) of the UDI were significantly higher in the abdominal group than in the vaginal group. Findings at pelvic examination were similar in both groups. Doctor visits because of pelvic floor symptoms were more frequent in the abdominal group than in the vaginal group. Re-operation was performed or planned in 9 of the 41 patients who underwent abdominal surgery and in 1 of the 41 patients who underwent vaginal surgery (odds ratio [OR] = 11.2, 95% CI 1.4-90.0).
                Our findings suggest that vaginal hysterectomy with anterior and/or posterior colporraphy is preferable to abdominal sacro-colpopexy with preservation of the uterus as surgical correction in patients with uterine prolapse stages II-IV. The objective of the study was to determine whether vaginal preparation with povidone iodine before cesarean delivery decreased the risk of postoperative maternal morbidities.
                The design of the study was a randomized, controlled trial in women undergoing cesarean delivery with subjects assigned to have a preoperative vaginal cleansing with povidone iodine or to a standard care group (no vaginal wash). The primary outcome was a composite of postoperative fever, endometritis, sepsis, readmission, wound infection, or complication.
                There were 155 vaginal cleansing subjects and 145 control subjects. Overall, 9.0% developed the composite outcome, with fewer women in the cleansing group (6.5%) compared with the control group (11.7%), although the difference was not statistically significant (relative risk, 0.55; 95% confidence interval, 0.26-1.11; P = .11). Length of surgery, being in labor, and having a dilated cervix were all associated with the composite morbidity outcome.
                Vaginal cleansing with povidone iodine before cesarean delivery may decrease postoperative morbidities, although the reduction is not statistically significant.
                Copyright 2010 Mosby, Inc. All rights reserved. To evaluate risk factors for anal incontinence using an identical twin sisters study design to provide control over genetic variance.
                A total of 271 identical twin sister pairs (mean age 47 years) completed the validated Colorectal Anal Distress Inventory questionnaire detailing the presence and severity of anal incontinence. Data were analyzed using a stepwise logistic regression with repeated binary measures to account for correlated data within twin pairs. Three different statistical models were used to analyze nonobstetric as well as obstetric risk factors separately.
                Significant risk factors for anal incontinence and higher Colorectal Anal Distress Inventory anal incontinence subscale scores included age 40 years or older (fecal: odds ratio [OR] 2.82, 95% confidence interval [CI] 1.21-6.0; flatal: OR 1.90, 95% CI 1.11-3.24), menopause (fecal: OR 2.10, 95% CI 1.15-3.8; flatal: OR 2.11, 95% CI 1.43-3.13), increasing parity (parity > or = 2; fecal: OR 3.09, 95% CI 1.25-7.65; flatal: OR 2.72, 95% CI 1.65-4.51), and the presence of stress urinary incontinence (fecal: OR 2.11, 95% CI 1.12-3.98; flatal: OR 1.72, 95% CI 1.14-2.59). Obesity was associated with significantly higher Colorectal Anal Distress Inventory anal incontinence subscale scores (mean difference 5.18, P = .007). Cesarean delivery after initiation of labor was associated with a lower prevalence of anal incontinence than vaginal birth; however, this difference was not statistically significant (17% compared with 4%, P = .11). No anal incontinence was noted in women who had only elective cesarean deliveries.
                Age, menopause, obesity, parity, and stress urinary incontinence are the major risk factors for female anal incontinence.
Without demonstrable benefit, preservation of anal continence should not be used as a criterion for choosing elective primary CD. The strength of this conclusion would be greatly strengthened if there were studies that randomised women with average risk pregnancies to CD versus VD.
