How Much Knowledge and Awareness of Faecal Incontinence Is There in Primary Care?

Faecal incontinence (FI) is a debilitating symptom with a likely underreported incidence in the general population. Postpartum or postmenopausal women are at increased risk of this. General Practitioners (GPs) have a vital role in screening patient groups with FI. Knowledge of the underlying diseases associated with FI is important for all clinicians who have contact with this patient group. An online questionnaire (Survey MonkeyTM, San Mateo, CA, USA) was sent to GPs in Wales and England through a deanery, social media and GP educational groups. Questions: A total of 250 participants completed the questionnaire—195 GPs and 55 GPSTs. Two-thirds had no coloproctology experience, but 70% had worked in obstetrics and gynaecology. In total, 70% had no formal FI training and 75% felt insufficiently informed about FI. A total of 80% felt that GPs need specific training on FI. A third of respondents used the 6-week postnatal check to assess maternal bowel function and most did not appreciate faecal urgency as a symptom. Patients should be asked about FI symptoms by GPs, particularly those populations at increased risk. Our GP survey participants were enthusiastic for more education on the treatment options and where to signpost patients with FI.

Dientamoeba fragilis – the most common intestinal protozoan in the Helsinki Metropolitan Area, Finland, 2007 to 2017

Background Despite the global distribution of the intestinal protozoan Dientamoeba fragilis, its clinical picture remains unclear. This results from underdiagnosis: microscopic screening methods either lack sensitivity (wet preparation) or fail to reveal Dientamoeba (formalin-fixed sample). Aim In a retrospective study setting, we characterised the clinical picture of dientamoebiasis and compared it with giardiasis. In addition, we evaluated an improved approach to formalin-fixed samples for suitability in Dientamoeba diagnostics. Methods This study comprised four parts: (i) a descriptive part scrutinising rates of Dientamoeba findings; (ii) a methodological part analysing an approach to detect Dientamoeba-like structures in formalin samples; (iii) a clinical part comparing demographics and symptoms between patients with dientamoebiasis (n = 352) and giardiasis (n = 272), and (iv) a therapeutic part (n = 89 patients) investigating correlation between faecal eradication and clinical improvement. Results The rate of Dientamoeba findings increased 20-fold after introducing criteria for Dientamoeba-like structures in formalin-fixed samples (88.9% sensitivity and 83.3% specificity). A further increase was seen after implementing faecal PCR. Compared with patients with giardiasis, the symptoms in the Dientamoeba group lasted longer and more often included abdominal pain, cramping, faecal urgency and loose rather than watery stools. Resolved symptoms correlated with successful faecal eradication (p < 0.001). Conclusions Previously underdiagnosed, Dientamoeba has become the most frequently recorded pathogenic enteroparasite in Finland. This presumably results from improved diagnostics with either PCR or detection of Dientamoeba-like structures in formalin-fixed samples, an approach applicable also in resource-poor settings. Symptoms of dientamoebiasis differ slightly from those of giardiasis; patients with distressing symptoms require treatment.

Microscopic colitis impacts quality of life in older people

This report describes a frail 92-year-old woman with dementia who presented with a year’s history of chronic watery non-bloody diarrhoea. She had abdominal bloating, weight loss, faecal urgency, nocturnal stools and developed faecal incontinence. Her serum C reactive peptide and faecal calprotectin were elevated. Flexible sigmoidoscopy was macroscopically normal, but demonstrated histological features of microscopic colitis (MC) in sigmoid colon and rectal biopsies. Polypharmacy was reviewed for possible medication-induced MC. Ranitidine, donepezil and simvastatin were discontinued. She was started on oral budesonide with improvement in the abdominal and bowel symptoms. Stool frequency and consistency normalised, and the faecal incontinence resolved with treatment. The outcomes were an improved quality of life, reduced functional dependency, reduced carer strain and avoidance of premature transition from her home into a long-term/institutional care setting. We briefly review terminology, basic epidemiology, notable associations, the importance of establishing a diagnosis and some treatment considerations for MC.

SACRAL NEUROMODULATION FOR THE TREATMENT OF FAECAL INCONTINENCE: FIRST STEPS IN LITHUANIA

Two female patients with faecal incontinence resistant to conservative treatment but improved after percutaneous tibial nerve neuromodulation were treated with sacral nerve neuromodulation in 2014. Quality of Life questionnaires were used in order to determine the impact of faecal incontinence on everyday life before and after the implantation of the stimulator. To evaluate the functional state, Wexner’s questionnaires were applied. Bowel movement diary was used to detect the improvement of faecal continence before and after temporary and permanent neuromodulation. The data were analyzed using a Statistical Package for Social Sciences program (SPSS, version 22.0). All values were given as mean ± SD. P-values less than 0.05 were accepted to indicate statistical significance. Both patients had a reduction in episodes of incontinence and soiling during a 3 week temporary nerve stimulation period as well as during 3 week followup after permanent stimulator implantation. Statistically significant elevation of faecal urgency frequency (p=0.031) was observed during temporary nerve stimulation. Reduction of episodes of faecal incontinence (p=0.001) and soiling (p=0.000) was observed after permanent stimulator implantation. Both patients presented an improvement in lifestyle, coping, depression and embarrassment as well as an improvement in functional state 3 weeks after the beginning of sacral nerve stimulation. Conclusions: The first results of sacral neuromodulation in patients with faecal incontinence are excellent and very promising. What does this paper add to the literature? The article describes the first Lithuanian experience applying the sacral nerve neuromodulation to treat faecal incontinence.

Prospective comparison of faecal incontinence grading systems

BackgroundExisting scales for assessing faecal incontinence have not been validated against clinical assessment, or with regard to reproducibility. They also fail to take into account faecal urgency, and the use of antidiarrhoeal medications.AimsTo establish the validity, and sensitivity to change, of existing scales and a newly designed incontinence scale.Methods(1) Twenty three patients (21 females, median age 57 years) were prospectively evaluated by two independent clinical observers, using three established scales (Pescatori, Wexner, American Medical Systems), a newly devised scale which also includes details about urgency and antidiarrhoeal drugs, and by a 28 day diary. (2) A further 10 female patients were assessed by the same scales before and after surgery for faecal incontinence.Results(1) Assessments by two independent clinicians correlated well. All four scales and a diary card correlated highly and significantly with the clinical impression, with the new scale reaching the highest correlation (r=0.79, p<0.001). (2) All except one score changed significantly in response to surgical treatment; the new scale showed the greatest change, at the highest level of significance (p=0.004), and correlated best with the clinicians’ assessment of change (r=0.94, p<0.001).ConclusionsExisting scales for the assessment of faecal incontinence correlate well with careful clinical impression of severity, and serve as useful and reproducible measures for comparison of patients and treatments. A newly devised scale has shown high clinical validity and utility.

Acute effects of therapeutic irradiation for prostatic carcinoma on anorectal function

Aim—The incidence of anorectal symptoms after radiotherapy (RTH) for localised pelvic malignant disease is unclear. In addition, the effects of pelvic irradiation on both anorectal motility and sensory function are poorly defined. A prospective study was therefore performed on 35 patients (55–82 years of age) with localised prostatic carcinoma before and four to six weeks after RTH to assess its effects on anorectal function.Methods—Anorectal symptoms were assessed by questionnaire. Anorectal pressures at rest and in response to voluntary squeeze, rectal distension, and increases in intra-abdominal pressure were evaluated with perfused sleeve side hole manometry. Rectal sensation was tested during graded balloon distension. Rectal compliance was calculated by the pressure-volume relation obtained during the testing of rectal sensation. Ultrasound was used to determine anal sphincter structure and integrity.Results—RTH had no effect on anal sphincter morphology. The frequency of defecation increased after RTH (7 (3–21) v 10 (3–56) bowel actions a week; p<0.01). After RTH, 16 patients had faecal urgency and eight faecal incontinence, compared with five and one respectively before RTH (p<0.01 for each). Basal and squeeze sleeve recorded pressures were reduced after RTH (54 (3)v 49 (3) mm Hg (p<0.05) and 111 (8)v 102 (8) mm Hg (p<0.01), before and after RTH respectively; means (SEM)). Rectal compliance was reduced after RTH (1.2 v 1.4 mm Hg/ml, p<0.05). After RTH, threshold volumes for perception of rectal distension were lower in the 16 patients who either experienced faecal urgency for the first time (13 patients) or reported worsening of this symptom (three patients) compared with the remaining patients (34 (4)v 48 (5) ml respectively, p<0.05).Conclusion—Faecal incontinence (23%) is a common problem four to six weeks after RTH for prostatic carcinoma and is associated with minor reductions in anal sphincter pressures. The high prevalence of faecal urgency in patients after RTH may be related to alterations in rectal perception of stool.
