The potential advantage of high-dose preoperative radiotherapy to increase tumor response and improve the chance of sphincter preservation for low rectal cancer remains controversial. The aim of this trial was to evaluate the role of escalating the dose of preoperative radiation to increase sphincter-saving procedures.
                Patients with rectal carcinoma located in the lower rectum, staged T2 or T3, Nx, or M0 with endorectal sonography, and not involving more than two-thirds circumference, were randomly assigned to one of two groups: preoperative external-beam radiotherapy (EBRT; 39 Gy in 13 fractions over 17 days) versus the same EBRT with boost (85 Gy in three fractions) using endocavitary contact x-ray.
                Between 1996 and 2001, 88 patients were enrolled onto the study. A significant improvement was seen in favor of the contact x-ray boost for complete clinical response (24% v 2%) and for a complete or near-complete sterilization of the operative specimen (57% v 34%). A significant increase in sphincter preservation was observed in the boost group (76% v 44%; P =.004). At a median follow-up of 35 months, there was no difference in morbidity, local relapse, and 2-year overall survival.
                A dose escalation with endocavitary irradiation provides increased tumor response and sphincter preservation with no detrimental effect on treatment toxicity and early clinical outcome. The present study assesses the choice of surgical procedure, oncologic results and quality of life (QOL) outcomes in a retrospective cohort of 53 patients with low-lying rectal cancers (within 6 cm of the anal verge) treated surgically following preoperative radiotherapy (RT, median dose 45Gy) with or without concomitant 5-fluorouracil. QOL was assessed in 23 patients by using two questionnaires developed by the QOL Study Group of the European Organization for Research and Treatment of Cancer: EORTC QLQ-C30 and EORTC QLQ-CR38. After a median interval of 29 days from completion of RT, abdominoperineal resection (APR) was performed in 29 patients (55%), low anterior resection in 23 patients (20 with coloanal anastomosis) and transrectal excision in one patient. The 3-year actuarial overall survival and locoregional control rates were 71.4% and 77.5% respectively, with no differences observed between patients operated by APR or restorative procedures. For all scales of EORTC QLQ-C30 and EORTC QLQ-CR38, no significant differences in median scores were observed between the two surgical groups. Although patients having had APR tended to report a lower body image score (P = 0.12) and more sexual dysfunction in male patients, all APR patients tended to report better physical function, future perspective and global QOL. In conclusion, sphincter-sparing surgery after preoperative RT seems to be feasible, in routine practice, in a significant proportion of low rectal cancers without compromising the oncologic results. However, prospective studies are mandatory to confirm this finding and to clarify the putative QOL advantages of sphincter-conserving approaches. The aim of this study was to compare the results of two surgical techniques (direct end-to-end vs. overlapping) of delayed repair of a localized anterior defect of external anal sphincter after an obstetric trauma.
                During a five-year period, 23 patients were randomly assigned to direct end-to-end repair (n = 12) or overlapping sphincter repair (n = 11), using 2-0 PDS sutures. Two patients from each group had an internal anal sphincter defect that also was repaired. All patients had a normal pudendal nerve terminal motor latency preoperatively. Evaluations included endoanal ultrasound, anorectal manometry, and neurophysiologic evaluation. Continence was assessed by the Cleveland Clinic Continence Score (0-20; 0, perfect continence; 20, complete incontinence).
                The two groups were comparable with regard to age (median, 45 years), past history of sphincter repair (n = 2), and posterior vaginal repair. There was no major morbidity. The wound-healing rate was identical between the two groups. However, of the patients undergoing overlapping repair, two had fecal impaction, and one had a urinary retention. Median preoperative continence score was 17 in both the direct-repair group (score, 8-20) and the overlap group (score, 7-20). At a median follow-up of 18 months, the improvement in continence was similar between the two surgical groups, with a median continence score of 3, respectively. In both surgical groups there was a significant and similar improvement in maximum squeeze pressure and in the functional anal canal length postoperatively (P < 0.05), but the mean resting pressure was relatively unchanged. In the overlap group, one patient developed a unilaterally prolonged pudendal nerve terminal motor latency that was persistent 22 months after surgery, and two patients had impaired fecal evacuation postoperatively.
                This randomized, controlled study suggests that the outcome is similar whether direct end-to-end or overlapping repair of a sphincter defect is performed. Overlapping repair might be associated with more difficulties with fecal evacuation and a prolonged pudendal nerve terminal motor latency postoperatively. To evaluate the impact of adjuvant biofeedback following sphincter surgery.
                Thirty-eight patients were randomized into sphincter repair or sphincter repair plus biofeedback groups. Outcome measures included a symptom questionnaire, patient's rating of satisfaction with continence function and improvement, change in continence score, quality of life and anorectal physiology. Endoanal ultrasonography was also performed pre- and post-operatively.
                Immediately following surgery, there was no statistically significant difference in any of the functional or physiological variables between the groups. Continence and patient satisfaction scores improved with a mean difference of -0.48 (95% CI: -3.30-2.33, P = 0.73) and 1.03 (95% CI: -1.40-3.46, P = 0.39), respectively. Only the difference in embarrassment scores reached statistical significance (mean) 0.56 (95% CI: 0.12-0.99, P = 0.014). Resting and squeeze pressures also improved. Thirteen of 14 in the biofeedback and 11 of 17 (control) reported symptomatic improvement. In the biofeedback group, although not statistically significant continence and satisfaction scores improved and were sustained over time. In the control group, continence and satisfaction scores changed little between 3 and 12 months (P = NS). Quality of life measures improved within the biofeedback group but there was no statistical difference between the groups.
                Following surgery continence function improves in all patients but adjuvant biofeedback therapy improves quality of life and maintains symptomatic improvement over time.
                Copyright 2004 Blackwell Publishing Ltd Survivors of high-risk surgical operations were previously observed to have significantly higher mean CI, DO2, and VO2 than nonsurvivors. The hypothesis was proposed that increased CI and DO2 are circulatory compensations for increased postoperative metabolism. We tested this hypothesis in two series. In series 1, prospectively allocated by services, mortality and morbidity of the control group were significantly greater than those of the protocol group. In series 2, patients who fulfilled previously defined high-risk criteria were preoperatively randomized to one of three monitoring/treatment groups: CVP-control group, PA-control group and PA-protocol group. Postoperative mortalities in the CVP-control and PA-control groups were not statistically significantly different, but PA-protocol group mortality was significantly reduced compared with its control group. The PA-protocol group had reduced complications, duration of hospitalization, duration in ICU, and mechanical ventilation, and reduced costs when the PA catheter was placed preoperatively and used to augment circulatory responses. The physiological and clinical effects of loperamide treatment versus placebo were investigated in a randomized, double-blind, crossover study in patients operated with restorative proctocolectomy. Sixteen patients operated with endoanal mucosectomy and a handsewn ileal pouch-anal anastomosis and 14 patients operated with abdominal proctocolectomy and stapling of the pouch to the top of the anal canal were studied. While loperamide treatment increased resting anal pressure in both groups of patients by approximately 20% (P < 0.05), squeeze pressure was not affected. Loperamide did not affect pouch volume or contractility. Sensory thresholds and the recto/pouch-anal inhibitory reflex were not influenced by loperamide treatment. Clinical function was improved, with a reduced bowel frequency and an improved nighttime continence, with less soiling (P < 0.05) as well as need to wear a protective pad. We tested hypertonic saline solution (HS) to determine its effectiveness in surgical procedures for prostatic hypertrophy. We randomly selected 40 patients undergoing elective transurethral resection of the prostate for either infusion of HS (3% NaCl) at 4ml·kg(-1)·min(-1) (HS group) or lactated Ringer's solution (LR) at 8 ml·kg(-1)·min(-1) (LR group). Anesthesiologists regulated the intraoperative infusion rate as needed to maintain blood pressure. There were no differences in systolic blood pressure, heart rate, central venous pressure, or arterial blood oxygenation between the two groups. In the HS group, plasma sodium, chloride, and osmolality, measured in the recovery room, were significantly increased; however, they returned to preanesthetic levels the day after surgery. In the LR group, in contrast, plasma sodium decreased significantly and this lower value persisted for 1 day. An osmolar gap exceeding 10mOsm·kg(-1) was observed in 2 patients in the HS group, but plasma sodium remained at normal values. However, in the 1 patient in the LR group whose osmolar gap exceeded 10mOsm·kg(-1), plasma sodium was 115 mEq·I(-1). HS, at a low dose, is useful in the intraoperative management of transurethral resection of the prostate. This study was designed to examine the role of adjuvant internal anal sphincter plication in women with neuropathic fecal incontinence undergoing pelvic floor repair.
                We completed a randomized trial with symptomatic and physiologic assessment before and after surgery.
                There was no symptomatic advantage of adding internal sphincter plication; the mean improvement of functional score was 3.61 +/- 1.82 (standard deviation; P < 0.01) following pelvic floor repair alone compared with 2.80 +/- 1.66 (standard deviation; P < 0.01) when adjuvant internal and sphincter plication was added. The addition of internal sphincter plication was associated with a significant fall in maximum anal resting and squeezing pressures (P < 0.01).
                Addition of internal sphincter plication is not advised in women with neuropathic fecal incontinence treated by pelvic floor repair. To assess the effectiveness and late postoperative morbidity of the Burch procedure and the sling procedure for the treatment of recurrent urinary stress incontinence after vaginal hysterectomy and anterior repair.
                Clinical, urodynamic, and sonographic examinations were done on 77 women suffering with recurrent urinary stress incontinence. The women were randomized to two groups, modified Burch colposuspension and lyophilized dura mater sling surgery; 72 women were reexamined 32-48 months after these procedures.
                The cure rate at 32-48 months' follow-up was 86% for the Burch procedure and 92% for the sling. Women who had had the sling procedure demonstrated a clear decrease in maximal bladder capacity, from 330 to 240 mL (P < .05). In both groups, stress profiles demonstrated a shift of maximal pressure point toward the proximal urethra and a significant improvement in pressure transmission (P < .05). The post-operative patients who had persistent incontinence were found to have insufficient elevation of the bladder neck (less than 10 mm). The uroflow examination showed an increase of urination time in both groups. The incidence of bladder problems was 10% with the Burch procedure and 29% with the sling procedure; however, 13% of the Burch group developed rectoceles.
                Both procedures offer a high rate of success. We believe that the sling surgery should be used only in certain special cases because of its higher rate of complications, but that posterior vaginal repair should be considered after modified Burch colposuspension because of the possibility of rectocele and enterocele. Endoscopic papillary balloon dilation (EPBD) is assumed to preserve sphincter of Oddi function because it causes little trauma to the papilla. However, few studies have addressed this issue specifically. In this study, we investigated whether EPBD can preserve sphincter function, and evaluated whether or not such preservation has clinical significance.
                Seventy patients with common bile duct (CBD) stones were randomly assigned to EPBD or endoscopic sphincterotomy (EST). Sphincter of Oddi (SO) function was measured by endoscopic manometry before, one week after, and one year after treatment. Incidence of pneumobilia and later complications were compared between the two groups at one year. Series manometric data were compared within each group and between the two groups. For a more detailed analysis of the cumulative incidence of later complications, retrospective cohorts were added to the study groups, giving a total number of 235 patients in the EPBD group and 126 in the EST group.
                Baseline characteristics did not differ significantly between the 35 EPBD and 35 EST patients. CBD stones were discharged successfully in all cases. CBD pressure, SO basal and peak pressures, and contraction frequency decreased significantly at one week in both groups. The damage was more severe in the EST group, and SO contraction completely disappeared in 23 patients in this group. The incidence of pneumobilia was significantly lower in the EPBD group than in the EST group (p<0.01) whereas CBD stones recurred and cholecystitis appeared at a similar rate in both groups at one year. A complete series of manometric data up to one year was obtained in 55 patients; 28 in the post-EPBD and 27 in post-EST groups. In the post-EPBD group, SO basal and peak pressures significantly recovered at one year compared with data at one week but these measures still remained significantly lower than those before EPBD (p< 0.01). In the post-EST group, SO contraction did not recover even after one year. A Kaplan-Meier analysis of 235 EPBD and 126 EST patients for a median follow up of 37 months revealed significantly lower incidences of biliary complications such as recurrent CBD stones and cholangitis, and cholecystitis in the EPBD group than in the EST group (p<0.05). The risk of pneumobilia was also significantly lower in the EPBD group (p<0.01).
                Preservation of papillary function after EPBD was not complete but remained somewhat reduced. However, preservation was more successful with EPBD than with EST. Such preservation may be clinically beneficial for the prevention of later complications. This study was designed to compare the results of controlled lateral internal sphincterotomy by using anal calibrators with those of sphincterotomy up to the fissure apex in a randomized, prospective fashion.
                In the fissure apex group, sphincterotomy was extended to the level of the fissure apex, and in the spasm-controlled group, serial small sphincterotomies and anal caliber measurements followed until an anal caliber of 30 mm was obtained.
                The preoperative anal caliber was 24 +/- 1.9 (range, 20-28) mm and 24.9 +/- 2.44 (range, 19-28) mm in the spasm-controlled and fissure apex groups, respectively (P = 0.127). Postoperatively, the spasm-controlled group had a mean anal caliber of 31.5 +/- 1.28 (range, 30-32) mm, and the fissure apex group had 32.5 +/- 2.33 (range, 25-37) mm (P = 0.035). In the fissure apex group, a significant negative correlation was determined between the postoperative anal caliber and time of relief of pain (r = -0.568, P = 0.001). The early (7 and 28 days) postoperative anal incontinence scores were significantly higher in the fissure apex group (P = 0.002, P < 0.0001, respectively). A significant positive correlation between the anal caliber measurements and anal incontinence scores at 28 days and 2 months also was noted in the fissure apex group (r = 0.406, P = 0.023; and r = 0.364, P = 0.044).
                Controlled sphincterotomy provided a faster relief of pain, and it was associated with a lower rate of early postoperative disturbance of continence and an insignificantly lower rate of treatment failure compared with sphincterotomy up to the fissure apex. Severe fecal incontinence remains a disabling condition for the patient and a major therapeutic challenge for the physician. A series of observational studies have indicated that placement of an artificial bowel sphincter is associated with marked improvement of continence and quality of life. We have performed a prospective, randomized, controlled trial to evaluate the effect of placement of an artificial bowel sphincter (Acticon Neosphincter) on continence and quality of life in a group of severely incontinent adults.
                Fourteen adults (male:female, 1:13; age range, 44-75 years) were randomized to placement of the artificial bowel sphincter or to a program of supportive care and were followed for six months from operation or entry into the study. The principal outcome measure was the level of continence, measured with the Cleveland Continence Score, which provides a scale from 0 to 20, representing perfect control through to total incontinence. Secondary outcome measures were perioperative and late complications in the artificial bowel sphincter group, and the changes in quality of life in both groups.
                In the control group, the Cleveland Continence Score was not significantly altered, with an initial value of 17.1 +/- 2.3 and a final value of 14.3 +/- 4.6 at six months. The artificial bowel sphincter group showed a highly significant improvement, changing from 19.0 +/- 1.2 before placement to 4.8 +/- 4.0 at six months after placement. One patient in the artificial bowel sphincter group had failure of healing of the perineal wound and explantation of the device (14 percent explantation rate). There were two other significant perioperative events of recurring fecal impaction initially after placement in one patient and additional suturing of the perineal wound in another. There were major improvements in the quality of life for all measures in the artificial bowel sphincter group. There was significant improvement in all eight subscales of the Medical Outcome Study Short Form-36 measures. The American Medical Systems Quality of Life score was raised from 39 +/- 6 to 83 +/- 14 and the Beck Depression Inventory showed reduction from a level of mild depression (10.8 +/- 9.3) to a normal value (6.8 +/- 8.7). No significant changes in any of the quality of life measures occurred for the control group.
                Through a prospective, randomized trial format, we have shown that placement of an artificial bowel sphincter is safe and effective when compared with supportive care alone. Perioperative and late problems are likely to continue to occur and between 15 percent and 30 percent of patients may require permanent explantation. For the remainder, the device is easy and discrete to use, highly effective in achieving continence, and able to generate a major improvement in the quality of life. 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. The aim of this study was to determine by means of a national database whether higher surgeon caseload correlates with greater utilization of sphincter-sparing procedures than of abdominoperineal resections in treatment of patients with rectal cancer.
                Patients with a primary International Classification of Diseases-9 diagnosis code of rectal cancer who underwent a sphincter-sparing procedure or abdominoperineal resection were selected from the 1997 Nationwide Inpatient Sample, a database that represents 20 percent of all U.S. community hospital discharges. Multivariable logistic regression models were used on a 20 percent sample of this database to estimate the risk-adjusted relationship between surgeon caseload volume and the odds of receiving a sphincter-sparing procedure. All models were adjusted for age, gender, race, hospital region, and patient comorbidity.
                The study population (n = 477) was 70.4 percent white and 57.9 percent male with an average age of 67.6 years. The mean Deyo comorbidity score was 7.0. Patients treated by surgeons in the highest-volume category (> or =10 rectal cancer surgeries per year) compared with those treated by surgeons in the lowest-volume category (1-3 rectal cancer surgeries per year) were significantly more likely to undergo a sphincter-sparing procedure, after adjustment for other covariates (odds ratio = 5.05; 95 percent confidence interval, 2.5-10.22).
                This analysis suggests that rectal cancer patients treated by high-volume surgeons are five times more likely to undergo sphincter-sparing procedures than those treated by low-volume surgeon. This has significant implications for those seeking a sphincter-preserving option for the treatment of their rectal cancer. 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. To determine the least invasive surgical procedure by comparing the levels of operative stress hormones, response-reactive protein (CRP) and rest energy expenditure (REE) after laparoscopic (LC) and open cholecystectomy (OC).
                Twenty-six consecutive patients with noncomplicated gallstones were randomized for LC (14) and OC (12). Plasma concentrations of somatotropin, insulin, cortisol and CRP were measured. The levels of REE were determined.
                In the third postoperative day, the insulin levels were lower compared to that before operation (P<0.05). In the first postoperative day, the levels of somatotropin and cortisol were higher in OC than those in LC. After operation the parameters of somatotropin, CRP and cortisol increased, compared to those in the preoperative period in the all patients (P<0.05). In the all-postoperative days, the CRP level was higher in OC than that in LC (7.46+/-0.02; 7.38+/-0.01, P<0.05). After operation the REE level all increased in OC and LC (P<0.05). In the all-postoperative days, the REE level was higher in OC than that in LC (1438.5+/-418.5; 1222.3+/-180.8, P<0.05).
                LC results in less prominent stress response and smaller metabolic interference compared to open surgery. These advantages are beneficial to the restoration of stress hormones, the nitrogen balance, and the energy metabolism. However, LC can also induce acidemia and pulmonary hypoperfusion because of the penumoperitonium it uses during surgery. Elective laparoscopic cholecystectomy is established as the treatment of choice for symptomatic cholecystolithiasis and is now proposed for the treatment of acute cholecystitis. The aim of this study is to evaluate biochemical aspects of open (OC) and laparoscopic cholecystectomy (LC). We measured the levels of malondialdehyde (MDA) and the levels of nitrite+nitrate as stable end products of nitric oxide (NO). MDA and nitrite+nitrate levels were increased at both surgical procedures compared to preoperative period, but the rise was more significant in OC than LC. These results showed that both OC and LC caused an increase in oxidative stress. However LC caused significantly less oxidative stress and the changes during surgery returned to preoperative values after LC in a shorter period. The beneficial effects of laparoscopic surgery may be related, partially, to less oxidative stress in the immediate postoperative period. Modern sphincter-preserving surgery for ultralow rectal carcinoma has a comparable oncological radicality to abdomino-perineal extirpation (APE). The aim of this study was to assess the long-term morbidity of ultralow anterior resection (ULAR) and its impact on quality of life (QoL) METHODS: The medical records of 142 consecutive patients who underwent surgery for ultralow rectal carcinoma from January 1991 to December 2004 were reviewed retrospectively. The rate of rehospitalisation and rate of non-reversed temporary stomas ("failure" stoma) were analysed. Generic and cancer-specific quality of life questionnaires were used to assess quality of life.
                There were a total of 82 ULAR and 60 APE. After ULAR, 25 (30.5%) of the patients were readmitted, stenosis and anastomotic leakage being the main reasons. After APE, only 2 (3.3%) of the patients were readmitted (P < 0.001). The rate of patients with a permanent stoma after sphincter-saving surgery was 22.0%. The failure rate was higher for older patients (P = 0.005) and for coloanal pull-through anastomosis (P = 0.001). The exploratory analysis revealed a negative impact of a "failure" stoma on QoL.
                Severe long-term morbidity and high failure rate of stoma reversal have a significantly worse impact on QoL after ULAR; therefore, APE is a valid alternative to ULAR, especially in elder patients with planned coloanal pull-through anastomosis. The aim of this retrospective study was to compare the functional and clinical results of laparoscopic rectopexy with those of the open technique in two similar groups of patients with complete rectal prolapse and fecal incontinence. Between November 1992 and June 1997, 21 patients underwent abdominal rectopexy. Thirteen patients (group A: 12 women and 1 man, mean age 52.9 years, range 28-70) and 8 patients (group B: 8 women, mean age 58.2 years, range 20-76) were submitted to Well's rectopexy by the open technique and the laparoscopic approach, respectively, without division of the lateral rectal ligaments. Assignment to each group was done randomly. Before the operation, a detailed clinical history was taken, and patients were studied with inspection and digital examination of the anorectum, proctosigmoidoscopy, determination of pancolonic transit time, dynamic defecography, anorectal manometry, and anal electromyography. After the operation, all patients underwent perineal physiotherapy, external electric stimulation, and perineal biofeedback. The mean follow-up time was 29.5 months (range 6-54) in group A and 25.7 months (range 8-45) in group B. Values were compared by chi-square, Mann-Whitney U, and Wilcoxon tests, as appropriate; differences were considered significant at p < 0.05. In both groups, dyschezia and fecal incontinence improved significantly (p < 0.05) after the operation. Basal pressure of anal sphincter, squeezing pressure, and rectoanal reflex improved without significance, whereas anoperineal pain was not significantly reduced. In group B, the postoperative hospital stay was shorter than in group A, with a marked reduction of costs. Laparoscopic Well's rectopexy has the same clinical and functional results as the open technique, with a shorter postoperative hospital stay and lower costs. The purpose of this study was to compare intra-anal electromyographic biofeedback alone with intra-anal biofeedback that was augmented with electrical stimulation of the anal sphincter in the treatment of postpartum fecal incontinence. A secondary aim was to examine the impact of the treatment on continence-related quality of life.
                Sixty symptomatic women were assigned randomly to receive intra-anal electromyographic biofeedback or electrical stimulation of the anal sphincter once weekly for 12 weeks and to perform daily pelvic floor exercises between treatments. Therapeutic response was evaluated with a symptom questionnaire to determine continence score, anal manometry, and endoanal ultrasound scanning. Quality of life was assessed before and after treatment with a validated questionnaire.
                Fifty-four women completed the treatment; 52 women (96%) had ultrasonic evidence of an external anal sphincter defect. After the treatment, both groups demonstrated significant improvement in continence score (P < .001) and in squeeze anal pressures (P < .04). Resting anal pressures did not alter significantly. Quality of life improved after the completion of physiotherapy, but there were no differences in outcome between intra-anal electromyographic biofeedback and electrical stimulation of the anal sphincter.
                Intra-anal electromyographic biofeedback therapy was associated with improved continence and quality of life in women with altered fecal continence after delivery. The addition of electrical stimulation of the anal sphincter did not enhance symptomatic outcome.
Optimal PRT improves LR, OA mortality, but no increase in sphincter sparing procedure. CRT further increases local control. If the objective is to increase the incidence of sphincter sparing surgery, endocavitary boost showed the most promise. Strategies with the potential to improve outcomes, especially OAS and spincter sparing while reducing acute and late toxicities (rectal and sexual function) are needed to guide future strategy designs.
