Long-term results of total pelvic floor repair for postobstetric fecal incontinence

Baiona's Consensus Statement for Fecal Incontinence. Spanish Association of Coloproctology

Faecal incontinence (FI) is a major health problem, both for individuals and for health systems. It is obvious that, for all these reasons, there is widespread concern for healing it or, at least, reducing as far as possible its numerous undesirable effects, in addition to the high costs it entails. There are different criteria for the diagnostic tests to be carried out and the same applies to the most appropriate treatment, among the numerous options that have proliferated in recent years, not always based on rigorous scientific evidence. For this reason, the Spanish Association of Coloproctology (AECP) proposed to draw up a consensus to serve as a guide for all health professionals interested in the problem, aware, however, that the therapeutic decision must be taken on an individual basis: patient characteristics/experience of the care team. For its development it was adopted the Nominal Group Technique methodology. The Levels of Evidence and Grades of Recommendation were established according to the criteria of the Oxford Centre for Evidence-Based Medicine. In addition, expert recommendations were added briefly to each of the items analysed.

Suboptimal results after sphincteroplasty: another hazard of obesity

BACKGROUND

This study aimed to investigate the outcomes of sphincteroplasty in obese patients.

METHODS

Patients with fecal incontinence (FI) who underwent sphincter repair were identified and divided into obese [body mass index (BMI) ≥ 30 kg/m(2)] and nonobese (BMI < 30 kg/m(2)) groups. Cleveland Clinic Florida FI Score (CCFFIS: 0 best and 20 worst) and FI quality of life (FIQoL) score (mean global FIQoL: 4.11 best and 1 worst) were recorded. Wilcoxon and Mann-Whitney U tests compared quantitative variables; Fisher's exact test was used for categorical variables.

RESULTS

Seventy-nine patients (78 females; mean age: 57 ± 15 years) were divided into obese (n = 15) and nonobese (n = 64) groups and were similar in age, etiology, physiologic parameters, and preoperative CCFFIS. Median follow-up was 64 (13-138) months. There were 3 (25 %) and 11 (17 %) complications in the obese and nonobese groups, respectively (p = 0.68), the most common being wound infection. Mean CCFFIS decreased from 16.0 ± 3.9 to 11.5 ± 6.5 in the obese (p < 0.001) and 16.2 ± 3.4 to 8.4 ± 5.0 in the nonobese groups (p < 0.001). Postoperative CCFFIS correlated with FIQoL (Spearman's correlation coefficient = -0.738, p < 0.001). Nonobese patients had significantly higher CCFFIS improvement (48 vs. 28 % p = 0.04) and a superior mean global FIQoL score (2.19 ± 0.9 vs. 2.93 ± 0.8, p < 0.01). Four (29 %) obese and 11 (17 %) nonobese patients required further surgery after failed sphincteroplasty (p = 0.45).

CONCLUSIONS

Risk of complications and need of further continence surgery were similar between obese and nonobese patients. However, obese patients experienced less improvement after sphincteroplasty.

Fecal incontinence: part 4 of a series of articles on incontinence

BACKGROUND

The aging of the population will make fecal incontinence an increasingly important socioeconomic problem in the coming decades. Already today, the cost to society of treating incontinence with inserts, diapers, and closed systems exceeds the total cost of all cardiac and anti-inflammatory medications.

METHODS

This article is based on a selective review of the literature and on clinical experience. No meta-analyses on this topic have yet been published.

RESULTS

Surveys in highly industrialized countries in the Western Hemisphere have shown that about 5% of the population suffers from fecal incontinence of varying degrees of severity. This condition will become more common, in both relative and absolute terms, in the coming decades. Various methods of care and therapy are currently available for fecal incontinence, yet many patients do not seek medical help for it because of embarrassment. Thus, its true prevalence is certainly higher than the surveys imply.

CONCLUSION

The challenge today, therefore, is not just to encourage patients to seek medical help early, but also to raise physicians' awareness of fecal incontinence and their readiness to treat it, so that they can provide competent individual counseling and treatment to all patients who suffer from it.

Effect of surgically induced weight loss on pelvic floor disorders in morbidly obese women

OBJECTIVE

To evaluate the effect of surgically induced weight loss on pelvic floor disorders (PFD) in morbidly obese women.

SUMMARY BACKGROUND DATA

Although bariatric surgery may lead to the improvement of some obesity-related comorbidities, the resolution of global PFD has not been well described.

METHODS

Women with a body mass index (BMI) of 35 kg/m(2) or more who were considering bariatric surgery were asked to complete 2 validated condition-specific questionnaires assessing the distress/quality of life impact of PFD, total and by domain (pelvic organ prolapse, colorectal-anal, and urogenital). Women who achieved a > or =50% excess body weight loss after surgery were asked to complete the same questionnaires for comparison.

RESULTS

Of the 178 women who underwent surgery, 46 completed the postoperative questionnaires. Mean age of this group was 45 years (range, 20-67), and mean preoperative BMI was 45 kg/m(2) (range, 35-75). The prevalence of PFD symptoms improved from 87% before surgery to 65% after surgery (P = 0.02, 95% CI: 0.05%-53%). There was a significant reduction in total mean distress scores after surgery (P = 0.015, 95% CI: 3.3-32.9), which was attributed mainly to the significant decrease in urinary symptoms (P = 0.0002, 95% CI: 8.2-22.7). Reductions in the scores were noted for the other PFD domains as well. Quality of life total scores improved (P = 0.002, 95% CI: 4.8-27.1), as did scores in the urinary domain (P = 0.0005, 95% CI: 3.8-13.5) and the pelvic organ prolapse domain (P = 0.015, 95% CI: 0.6-9.5). Age, parity, history of complicated delivery, percent excess body weight loss, BMI, type of weight loss procedure and presence of diabetes mellitus and hypertension had no predictive value for postoperative outcomes.

CONCLUSION

Surgically induced weight loss has a beneficial effect on symptoms of PFD in morbidly obese women.

Imbrication of the external anal sphincter may yield similar functional results as overlapping repair in selected patients

OBJECTIVE

Overlapping external anal sphincter repair is the preferred procedure for incontinent patients with functional yet anatomically disrupted anterior external anal sphincter. When incomplete disruption, thinning or technically difficult mobilization of the external anal sphincter occurs, imbrication without division may be the more feasible surgical option. The aim of the study was to assess retrospectively the indications for external anal sphincter imbrication in patients who underwent either overlapping external anal sphincter repair or external anal sphincter imbrication, and to compare the success rates.

METHOD

Patients who had external anal sphincter repair and follow up of at least 3 months were studied. Fecal incontinence was measured using the validated Wexner fecal Incontinence Scoring system (0 = perfect continence, 20 = complete incontinence); postoperative scores 0-10 were interpreted as successful, and scores of 11-20 as failures.

RESULTS

A total of 131 females who had anal sphincter repair between 1988 and 2000 were analysed. One hundred and twenty-one patients had overlapping external anal sphincter repair (group I), and 10 had external anal sphincter imbrication (group II). Indications for external anal sphincter imbrication were attenuation of the external anal sphincter without overt defect (n = 5), partial disruption of external anal sphincter with muscle fibres bridging the scar (n = 2), thick bulk of scar between the muscle edges (n = 2), and wide lateral retraction of the muscle edges (n = 1). There were no statistically significant differences between the groups relative to preoperative incontinence score (16.5 vs 16.5, P = 0.99), pudendal nerve terminal motor latency assessment (left 9.6%vs 0.0%, P = 0.19; right 13.4%vs 11.1%, P = 0.84), and extent of electromyography pathology (61%vs 47%, P = 0.30). The patients in group I were younger than those in group II (mean age 50.8 years vs. 61.7 years, respectively; P = 0.052) and the length of follow-up was significantly longer (32.3 months vs 14.3 months, respectively; P < 0.0001). Both procedures had similar success rates (59.5%vs 60%; P = 0.98).

CONCLUSION

Imbrication of the external anal sphincter may yield similar results as overlapping external anal sphincter repair in patients with incomplete external anal sphincter disruptions, external anal sphincter attenuation, and in patients presenting with wide lateral retraction of the muscle edges.

Obesity and pelvic floor disorders: a systematic review

OBJECTIVE

To review the current literature and summarize the effect of obesity on outcomes of surgical treatment of pelvic floor disorders as well as the effect of weight loss on pelvic floor disorder symptoms.

DATA SOURCES

Relevant sources were identified by a MEDLINE search from 1966 to 2007 using the key words obesity, pelvic floor disorders, urinary incontinence (UI), fecal incontinence, and pelvic organ prolapse (POP). References of relevant studies were hand searched.

METHODS OF STUDY SELECTION

Relevant human observational studies, randomized trials, and review articles were included. A total of 246 articles were identified; 20 were used in reporting and analyzing the data. Meta-analyses were performed for topics meeting the appropriate criteria.

TABULATION, INTEGRATION, AND RESULTS

There is good evidence that surgery for stress UI in obese women is as safe as in their nonobese counterparts, but cure rates may be lower in the obese patient. Meta-analysis revealed cure rates of 81% and 85% for the obese and nonobese groups, respectively (P<.001; odds ratio [OR] 0.576, 95% confidence interval [CI] 0.426-0.779). Combined bladder perforation rates were 1.2% in the obese and 6.6% in the nonobese (P=.015; OR 0.277, 95% CI 0.098-0.782). There is little evidence on which to base clinical decisions regarding the treatment of fecal incontinence and POP in obese women, because few comparative studies were identified addressing the outcomes of prolapse surgery in obese patients compared with healthy-weight patients. Weight loss studies indicate that both bariatric and nonsurgical weight loss lead to significant improvements in pelvic floor disorder symptoms.

CONCLUSION

Surgery for UI in obese women is safe, but more trials are needed to evaluate its long-term effectiveness as well as treatments for both fecal incontinence and POP. Weight loss, both surgical and nonsurgical, should be considered in the treatment of pelvic floor disorders in the obese woman.

Surgical treatment of patients with constipation and fecal incontinence

Patients with constipation and fecal incontinence usually come to the attention of the surgeon when conservative measures have failed to alleviate sufficiently severe symptoms. Following detailed clinical and physiologic assessment, the surgeon should tailor the procedure to specific underlying physiologic abnormalities to restore function. This article describes the rationale, indications (including patient selection), results, and current position controversies of surgical procedures for constipation and fecal incontinence, dividing these into those regarded as historical, contemporary, or evolving. Reported surgical outcome data must be interpreted with caution because for most studies the evidence is of low quality, making comparison of different procedures problematic and emphasizing the need for better designed and conducted clinical trials.

Fecal incontinence: an up-to-date critical overview of surgical treatment options

BACKGROUND

Surgery is the last resort for patients suffering from severe fecal incontinence. The armamentarium of surgical options for this condition has increased impressively during the last decade. Nevertheless, this fact seems to make neither patients nor surgeons feel more comfortable. Treatment of fecal incontinence still remains a challenge to modern medicine due to many specific sides of this problem.

AIMS

This article gives an up-to-date overview of existing operative treatment options.

METHODS

An unbiased review of relevant literature was performed to assess the role of all methods of surgical treatment for fecal incontinence available nowadays.

RESULTS

Recent studies have shown poor late results after primary sphincter repair and low predictive value for most preoperative diagnostic tests. New surgical options such as artificial devices and electrically stimulated muscle transpositions are doomed by low success rates and unacceptably frequent complications. That is why current attention has focused on non- or minimally invasive therapies such as sacral nerve stimulation and temperature-controlled radio-frequency energy delivery to the anal canal. However, all these innovative techniques remain experimental till enough high-evidence data are gathered for their objective evaluation.

CONCLUSION

Careful and detailed preoperative assessment to exactly determine the etiology of incontinence and individual approach remain the cornerstones of surgical treatment of fecal incontinence nowadays.

Treatment of Fecal Incontinence

Fecal incontinence is a symptom of many disorders that can affect the nerves and muscles controlling defecation; it is not just due to exceptionally voluminous diarrhea. Underlying problems should be identified and treated, because that may improve incontinence. If treatment of the underlying problem does not correct incontinence, several approaches can be employed successfully. General approaches include stimulation of defecation at intervals to empty the rectum under supervised conditions; treatment of diarrhea, if present; addressing coexisting psychologic problems, such as depression; use of continence aids, such as adult diapers; and perineal skin care to prevent skin breakdown. Drug therapy includes use of constipating drugs, such as loperamide or diphenoxylate, that can impede the gastrocolic reflex, thereby limiting rectal filling and the likelihood of incontinence. Biofeedback training is useful in patients with some ability to sense rectal distention and to contract the external anal sphincter; instrumental learning using manometric or electromyographic biofeedback can be used to reinforce the rectoanal contractile response to rectal distention. Improvement in continence has been noted in up to 70% of suitable candidates with a single biofeedback training session. Patients with external anal sphincter disruption due to childbirth injury or other trauma may benefit from direct external anal sphincter repair (sphincteroplasty). In others, tightening up the anal canal by encirclement with nonabsorbable mesh (Thiersch procedure), perianal injection of fat, collagen, or synthetic gel, or radiofrequency electrical energy (Stretta procedure) may provide some palliation. Creation of a new sphincter mechanism by muscle transposition and encirclement of the anal canal is another approach that has been improved by use of electrical stimulators to keep the neosphincter contracted. Artificial anal sphincters patterned after artificial urinary sphincters have met with some success, but local infection remains problematic. When all else fails, fecal diversion (ileostomy, colostomy) can be effective in rehabilitating patients.

Fecal incontinence: evaluation and treatment

Fecal incontinence affects men and women of all ages, leading to personal disability and high financial costs. The evaluation of the patient should clarify the pathophysiology of the symptoms and provide guidance in choosing the appropriate treatment. A comprehensive history and physical examination including endoscopic assessment is able to identify the cause of most cases of fecal incontinence. If necessary, functional methods can be used to confirm the diagnosis. Patient selection for suitable treatment is most important and should be based on clinical and physiologic findings. Conservative dietary or medical treatment is often effective, when the symptoms are mild. Biofeedback therapy is effective in most patients. It has no side effects and is well tolerated. Structural damage to the anus may be repaired by surgery, like sphincter repair, the best treatment of selective sphincter defects. Neoanal sphincters and artificial sphincters are the last possibility after failed surgery and before colostomy. They are less attractive because of technical difficulties and low success rate. A multidisciplinary approach to treatment has the potential to improve the outcome for patients with fecal incontinence.

Surgical treatment of constipation and fecal incontinence

Fecal incontinence is a disabling and distressing condition. Many patients are reluctant to discuss the condition with a physician. A thorough history, good physical examination, and detailed anorectal physiologic investigations can help in the therapeutic decision-making algorithm. Patients with isolated anterior sphincter defects are candidates for overlapping repair. In the presence of unilateral or bilateral pudendal neuropathy, the patient should be counseled preoperatively regarding a [table: see text] lower anticipation of success. If the injury occurred shortly before the planned surgery and neuropathy is present, it may be prudent to wait because neuropathy sometimes can resolve within 6 to 24 months of the injury. Pudendal nerve study may help determine surgical timing. An anterior sphincter defect combined with a rectovaginal fistula can be approached by overlapping sphincter repair and a concomitant transanal advancement flap. Patients who had undergone multiple such procedures may benefit from concomitant fecal diversion at the time of repeat sphincter repair. Patients with global or multifocal sphincter injury may be candidates for a neosphincter procedure. The stimulated graciloplasty and artificial bowel sphincter are reasonable options. In the absence of the availability of these techniques or because of financial constraints, consideration could be given to bilateral gluteoplasty or unilateral or bilateral nonstimulated graciloplasty. The postanal repair still serves a role in patients with isolated decreased resting pressures with or without neuropathy or external sphincter injury with minimal degrees of incontinence. Biofeedback and the Procon device may play a role in these patients. Lastly, fecal diversion must be considered as a means of improving the quality of life because the patient can participate in the activities of daily living without the fear of fecal incontinence.

What is the impact of fecal incontinence on quality of life?

PURPOSE

The objective of this study was to determine at what point fecal incontinence affects quality of life.

METHODS

In 35 patients who had anterior sphincter repair for fecal incontinence as a result of obstetric injury, continence evaluated by the Wexner score was compared with validated quality of life tests (Gastrointestinal Quality of Life Index and Medical Outcomes Study Short-Form General Health Survey). The questionnaires were sent by mail. Thirty-two patients responded. The Wexner score (0-20) was correlated with the Gastrointestinal Quality of Life Index and the Medical Outcomes Study Short-Form General Health Survey and matched with those of reference groups.

RESULTS

The mean Wexner score was 8.8, corresponding with losing stools between once a week and once a month. The mean Gastrointestinal Quality of Life Index score was 105 (range, 48-136), which is significantly lower than the score found in a reference group of normal individuals. Medical Outcomes Study Short-Form General Health Survey scores were significantly lower in all six dimensions compared with the reference group. A Wexner score of 9 or higher was associated with a Gastrointestinal Quality of Life Index score of less than 105, which implies that patients were less mobile in the community and were confined to their homes. A similar correlation was found between a Wexner score higher than 9 and the Medical Outcomes Study Short-Form General Health Survey.

CONCLUSIONS

A Wexner score of 9 or higher indicates a significant impairment of quality of life and can therefore be used in decision making.

Long-term results of overlapping anterior anal-sphincter repair for obstetric trauma

BACKGROUND

Anterior structural damage to the anal sphincter occurs in up to a third of women at first vaginal delivery, and of these a third have new bowel symptoms. The standard treatment for such structural damage is anterior overlapping anal-sphincter repair. We aimed to assess the long-term results of this operation.

METHODS

We assessed the long-term results in 55 consecutive patients who had had repair a minimum of 5 years (median 77 months [range 60-96]) previously. Questionnaire and telephone interview assessed current bowel function and continence, restriction in activities related to bowel control, and overall satisfaction with the results of surgery. 42 of these patients had been continent of solid and liquid stool at a median of 15 months after the repair.

FINDINGS

We were able to contact 47 (86%) of the 55 patients. One of these patients had required a proctectomy and end ileostomy for Crohn's disease. Of the remaining 46 patients, 27 reported improved bowel control without the need for further surgery, and 23 rated their symptom improvement as 50% or greater. Seven patients had undergone further surgery for incontinence and one patient had not had a covering stoma closed. Thus, the long-term functional outcome of the sphincter repair alone could be assessed in 38 patients. Of these patients, none was fully continent to both stool and flatus; only four were totally continent to solid and liquid stool; six had no faecal urgency; and eight had no passive soiling. Of the 38 patients, 20 still wore a pad for incontinence and 25 reported lifestyle restriction. 14 reported the onset of a new evacuation disorder after sphincter repair. 23 of the 46 patients contacted had a successful long-term outcome (defined as no further surgery and urge faecal incontinence monthly or less).

INTERPRETATION

The results of overlapping sphincter repair for obstetric anal-sphincter damage seem to deteriorate with time. Preoperative counselling should emphasise that although most patients will improve after the procedure, continence is rarely perfect, many have residual symptoms, and some may develop new evacuation disorders.

A pilot study of total pelvic floor repair or gluteus maximus transposition for postobstetric neuropathic fecal incontinence

PURPOSE

The aim of this study was to report pilot data comparing the morbidity and functional outcome of total pelvic floor repair with gluteus maximus transposition for women with postobstetric fecal incontinence.

METHODS

This is a prospective, randomized trial of two surgical procedures in 24 women so far. Functional assessment was performed with use of a 20-point clinical incontinence score and patient questionnaire before and after operation. The physiologic parameters, before and after operation, included resting and squeeze anal pressures, length of the high pressure zone, anal and rectal mucosal sensitivity, and pudendal nerve latency.

RESULTS

So far, 12 patients have been treated by total pelvic floor repair and 12 by gluteus maximus transposition. Of these, three patients developed wound complications after gluteus maximus transposition compared with none after total pelvic floor repair. Among these cases there was a significant overall improvement in functional score (given as mean +/- standard deviation) after both total pelvic floor repair (13.1 +/- 2.7 vs. 6.6 +/- 4.5; P < 0.001) and gluteus maximus transposition (13.8 +/- 3.8 vs. 7.7 +/- 6.1; P < 0.01), although no difference existed between the groups. There was no change in any of the physiologic measurements after either operation, and preoperative measurements did not identify patients likely to do badly.

CONCLUSIONS

We conclude from these preliminary data that both total pelvic floor repair and gluteus maximus transposition significantly improve continence in women with postobstetric neuropathic fecal incontinence. Gluteus maximus transposition gives equivalent results to total pelvic floor repair. Neither procedure has any influence on anorectal physiologic parameters.
