The success of treatment depends upon the exact causes and how easily these are corrected. Treatment choice depends on the cause and severity of disease, and the motivation and general health of the person affected. Commonly, conservative measures are used together, and if appropriate surgery carried out. Treatments may be attempted until symptoms are satisfactorily controlled. A treatment algorithm based upon the cause has been proposed, including conservative, non-operative and surgical measures (neosphincter refers to either dynamic graciloplasty or artificial bowel sphincter, lavage refers to retrograde rectal irrigation). Conservative measures include dietary modification, drug treatment, retrograde anal irrigation, biofeedback retraining anal sphincter exercises. Incontinence products refer to devices such as anal plugs and perineal pads and garments such as diapers/nappies. Perineal pads are efficient and acceptable for only minor incontinence. If all other measures are ineffective removing the entire colon may be an option. Diet Dietary modification may be important for successful management. Both diarrhea and constipation can contribute to different cases, so dietary advice must be tailored to address the underlying cause or it may be ineffective or counter productive. In persons with disease aggravated by diarrhea or those with rectal loading by soft stools, the following suggestions may be beneficial: increase dietary<unk> ber; reduce wholegrain cereals/bread; reduce fruit and vegetables which contain natural laxative compounds (rhubarb,<unk> gs, prunes/plums); limit beans, pulses, cabbage and sprouts; reduce spices (especially chilli); reduce artificial sweeteners (e.g. sugar free chewing gum); reduce alcohol (especially stout, beer and ale); reduce lactose if there is some degree of lactase deficiency; and reduce caffeine. Caffeine lowers the resting tone of the anal canal and also causes diarrhea. Excessive doses of vitamin C, magnesium, phosphorus and/or calcium supplements may increase<unk> . Reducing olestra fat substitute, which can cause diarrhea, may also help. Medication Pharmacological management may include anti-diarrheal/constipating agents and laxatives/stool bulking agents. Stopping or substituting any previous medication that causes diarrhea may be helpful in some (see table). There is not good evidence for the use of any medications, however. In people who have undergone gallbladder removal, the bile acid sequestrant cholestyramine may help minor degrees of<unk> . Bulking agents also absorb water, so may be helpful for those with diarrhea. A common side effect is bloating and flatulence. Topical agents to treat and prevent dermatitis may also be used, such as topical antifungals when there is evidence of perianal candidiasis or occasionally mild topical anti-inflammatory medication. Prevention of secondary lesions is carried out by perineal cleansing, moisturization, and use of a skin protectant. Other measures Evacuation aids (suppositories or enemas) e.g. glycerine or bisacodyl suppositories may be prescribed. People may have poor resting tone of the anal canal, and consequently may not be able to retain an enema, in which case transanal irrigation (retrograde anal irrigation) may be a better option, as this equipment utilizes an inflatable catheter to prevent loss of the irrigation tip and to provide a water tight seal during irrigation. A volume of lukewarm water is gently pumped into the colon via the anus. People can be taught how to perform this treatment in their own homes, but it does require special equipment. If the irrigation is efficient, stool will not reach the rectum again for up to 48 hours. By regularly emptying the bowel using transanal irrigation, controlled bowel function is often re-established to a high degree in patients with bowel incontinence and/or constipation. This enables control over the time and place of evacuation and development of a consistent bowel routine. However, persistent leaking of residual irrigation fluid during the day may occur and make this option unhelpful, particularly in persons with obstructed defecation syndrome who may have incomplete evacuation of any rectal contents. Consequently, the best time to carry out the irrigation is typically in the evening, allowing any residual liquid to be passed the next morning before leaving the home. Complications such as electrolyte imbalance and perforation are rare. The effect of transanal irrigation varies considerably. Some individuals experience complete control of incontinence, and other report little or no benefit. It has been suggested that if appropriate, people be offered home retrograde anal irrigation. Biofeedback (the use of equipment to record or amplify and then feed back activities of the body) is a commonly used and researched treatment, but the benefits are uncertain. Biofeedback therapy varies in the way it is delivered, but it is unknown if one type has benefits over another. The role of pelvic floor exercises and anal sphincter exercises in<unk>  is poorly determined. While there may be some benefit they appear less useful than implanted sacral nerve stimulators. These exercises aim to increase the strength of the pelvic floor muscles (mainly levator ani). The anal sphincters are not technically part of the pelvic floor muscle group, but the EAS is a voluntary, striated muscle which therefore can be strengthened in a similar manner. It has not been established whether pelvic floor exercises can be distinguished from anal sphincter exercises in practice by the people doing them. This kind of exercise is more commonly used to treat urinary incontinence, for which there is a sound evidence base for effectiveness. More rarely are they used in<unk> . The effect of anal sphincter exercises are variously stated as an increase in the strength, speed or endurance of voluntary contraction (EAS). Electrical stimulation can also be applied to the anal sphincters and pelvic floor muscles, inducing muscle contraction without traditional exercises (similar to transcutaneous electrical nerve stimulation, TENS). The evidence supporting its use is limited, and any benefit is tentative. In light of the above, intra-anal electrical stimulation (using an anal probe as electrode) appears to be more efficacious than intra-vaginal (using a vaginal probe as electrode). Rarely, skin reactions may occur where the electrodes are placed, but these issues typically resolve when the stimulation is stopped. Surgically implanted sacral nerve stimulation may be more effective than exercises, and electrical stimulation and biofeedback may be more effective than exercises or electrical stimulation by themselves. TENS is also sometimes used to treat<unk>  by transcutaneous tibial nerve stimulation. In a minority of people, anal plugs may be useful for either standalone therapy or in concert with other treatments. Anal plugs (sometimes termed tampons) aim to block involuntary loss of<unk>  material, and they vary in design and composition. Polyurethane plugs were reported to perform better than those made of polyvinyl-alcohol. Plugs are less likely to help those with frequent bowel movements, and many<unk> nd them difficult to tolerate. In women, a device that functions as an inflatable balloon in the vagina, has been approved for use in the United States. Surgery Surgery may be carried out if conservative measures alone are not sufficient to control incontinence. There are many surgical options, and their relative effectiveness is debated due to a lack of good quality evidence. The optimal treatment regime may be a both surgical and non-surgical treatments. The surgical options can be considered in four categories: restoration and improvement of residual sphincter function (sphincteroplasty, sacral nerve stimulation, tibial nerve stimulation, correction of anorectal deformity), replacement / imitation of the sphincter or its function (anal encirclement, SECCA procedure, non-dynamic graciloplasty, perianal injectable bulking agents), dynamic sphincter replacement (artificial bowel sphincter, dynamic graciloplasty), antegrade continence enema (Malone procedure), and<unk> nally<unk>  diversion (e.g. colostomy). A surgical treatment algorithm has been proposed. Isolated sphincter defects (IAS/EAS) may be initially treated with sphincteroplasty and if this fails, the person can be assessed for sacral nerve stimulation. Functional deficits of the EAS and/or IAS (i.e. where there is no structural defect, or only limited EAS structural defect, or with neurogenic incontinence) may be assessed for sacral nerve stimulation. If this fails, neosphincter with either dynamic graciloplasty or artificial anal sphincter may be indicated. Substantial muscular and/or neural defects may be treated with neosphincter initially.
