Fecal Incontinence: a woman's view

Effects of electroacupuncture combined with stem cell transplantation on anal sphincter injury-induced faecal incontinence in a rat model

BACKGROUND

Bone marrow mesenchymal stem cells (BMSCs) and acupuncture are known to mitigate tissue damage. This study aimed to investigate the therapeutic effects of combined electroacupuncture (EA) stimulation and BMSC injection in a rat model of anal sphincter injury-induced faecal incontinence (FI).

METHODS

60 Sprague-Dawley rats were randomly divided into five groups: sham-operated control, FI, FI+EA, FI+BMSC, and FI+BMSC+EA. The anorectal tissues were collected on days 1, 3, 7 and 14. Repair of the injured anal sphincter was compared using haematoxylin and eosin (HE) and immunocytochemiscal analyses with sarcomeric α actinin. The expression of stromal cell derived factor-1 (SDF-1) and monocyte chemoattractant protein-3 (MCP-3) was detected by quantitative reverse transcription PCR to evaluate the effects of EA on the homing of BMSCs.

RESULTS

The therapeutic effect of combined EA+BMSCs on damaged tissue was the strongest among all the groups as indicated by HE and immunohistochemical staining. The expression of SDF-1 and MCP-3 was significantly increased by combined EA and BMSC treatment when compared with the other groups (P=0.01 to P<0.05), suggesting promotive effects of EA on the homing of BMSCs.

CONCLUSION

The combination of EA and BMSC transplantation effectively repaired the impaired anal sphincters. The underlying mechanism might be associated with apparent promotive effects of EA on the homing of BMSCs. Our study provides a theoretical basis for the development of a non-surgical treatment method for FI secondary to muscle impairment.

Fecal incontinence in irritable bowel syndrome: Prevalence and associated factors in Swedish and American patients

BACKGROUND

Fecal incontinence (FI) is a prevalent but poorly recognized problem in the general population with profound negative effects on daily life. The prevalence of FI in irritable bowel syndrome (IBS) and its association with clinical, demographic, and pathophysiological factors remain largely unknown.

METHODS

One US (n=304) and one Swedish (n=168) patient cohort fulfilling Rome III criteria for IBS completed Rome III diagnostic questions on FI and IBS symptoms, and questionnaires on IBS symptom severity, quality of life, anxiety and depression, and work productivity impairment. The patients also underwent assessments of colorectal sensitivity and motility.

KEY RESULTS

Fecal incontinence ≥ one day per month was reported by 19.7% (USA) and 13.7% (Sweden) of IBS patients. These proportions rose to 43.4% and 29.8% if patients with less frequent FI were included. Fecal incontinence prevalence was higher in older age groups, with a clear increase above age 40. Irritable bowel syndrome patients with FI reported greater overall IBS symptom severity, more frequent and loose stools, and greater urgency. Negative effects of FI on quality of life, psychological distress, and work productivity were demonstrated. No associations were found between colorectal physiology and FI.

CONCLUSIONS & INFERENCES

Fecal incontinence is common in IBS patients, and similar to previous general population reports, the major risk factors for FI in IBS are older age, rectal urgency, and loose, frequent stools. When IBS patients have comorbid FI, the impact on quality of life, psychological symptoms, and work impairment appears greater.

Fecal incontinence: prevalence, severity, and quality of life data from an outpatient gastroenterology practice

Background. The prevalence of fecal incontinence varies tremendously as a result of inadequate data collection methods. Few office-based studies have assessed the prevalence of fecal incontinence and none have looked at modifiable risk factors or effect on quality of life. Design, Settings, Patients, and Main Outcome Measures. Five hundred patients who visited our inner city, university-based gastroenterology practice, were asked about symptoms of fecal incontinence. We also retrospectively reviewed 500 charts to identify the frequency of patient-physician reporting of fecal incontinence. Results. Of the 500 patients that were directly questioned, 58 (12%, 43 women, 15 men) admitted to fecal incontinence compared to 12 (2.4%) in the retrospective arm. Patients with fecal incontinence and loose/watery stool reported the lowest quality of life scores. While the average severity score was similar between men and women, women had a significantly lower average quality of life score (3.04 versus 2.51; P < 0.03). Conclusions. The identification of fecal incontinence increases when patients are directly questioned. Identifying and treating patients with loose stool is a potential strategy to improve quality of life in this patient population. In men and women with similar severity of fecal incontinence, women have a significantly lower quality of life.

Evidence-based practice guideline: wheelchair biking for the treatment of depression

Depression is a problem that will continue to burden older adults and challenge health care providers. Failing to recognize and effectively treat depression in institutionalized older adults is sanctioning these members of society to live their final years in despair and emotional suffering. The wheelchair biking program described in this evidence-based practice guideline provides a refreshing, safe, innovative tool to address depression and improve quality of life in older adults.

A global perspective on gastrointestinal diseases

Common gastrointestinal diseases often exhibit geographic, cultural, and gender variations. Diseases previously less common in certain areas of the world have shown a recent increase in prevalence. Industrialization has traditionally been noted as a major cause for this epidemiologic evolution. However, environmental factors such as diet, hygiene, and exposure to infections may play a major role. Moreover, the way one disease presents in a certain location may vary significantly from the way it manifests in another culture or location. This article discusses global variations of inflammatory bowel disease, Helicobacter pylori, irritable bowel disease, fecal incontinence, hepatitis B, and hepatocellular cancer.

Fecal incontinence

Fecal incontinence (FI) has a significant social and economic impact on the patient and the community. In women, obstetric injury is commonly associated with the development of FI. Understanding FI is aided by a good knowledge of the pelvic floor anatomy and continence mechanisms. This same knowledge along with a good history and physical can guide the physician in selecting appropriate studies and treatment options. Surgical treatment of FI is currently the best option when a sphincter defect exists. The long-term prognosis of the repair is disappointing, however. Ongoing investigations continue in the hopes of getting closer to a cure and to reclaiming the patient's former quality of life.

Somatic comorbidities of irritable bowel syndrome: a systematic analysis

OBJECTIVE

A large number of irritable bowel syndrome (IBS) patients are additionally afflicted with other somatic intestinal and/or extraintestinal comorbidities. The occurrence of one or more comorbidities is correlated with enhanced medical help seeking, worse prognosis, and higher rates of anxiety and depression-all resulting in a reduced quality of life. The aims of this study were, firstly, to review the literature on comorbidities of IBS and to assess gastrointestinal and extraintestinal comorbidities, and, secondly, to evaluate explanatory hypotheses and possible common pathophysiological mechanisms.

METHODS

We systematically reviewed the scientific literature in the past 25 years, as cited in MEDLINE.

RESULTS

IBS patients present with a twofold increase in somatic comorbidities compared to controls, possibly caused by common pathophysiological mechanisms. Nevertheless, to date, there has been no convincing evidence for a consolidated underlying pathophysiology or somatization. Gastrointestinal disorders, such as functional dyspepsia, gastroesophageal reflux disease, functional constipation, and anal incontinence, occur in almost half of the patients. In a broad variety of extraintestinal comorbidities, fibromyalgia, chronic fatigue syndrome, and chronic pelvic pain are best documented and appear in up to 65%.

CONCLUSION

The knowledge and structured assessment of comorbid somatic symptoms might allow to identify subgroups of IBS patients with special characteristics and lead to adaptation of the therapeutic concept.
