Impact of preoperative defecation pattern on postoperative constipation for patients undergoing cardiac surgery.

To analyse the impact of preoperative defecation pattern on postoperative defecation pattern for patients undergoing cardiac surgery. Constipation is a neglected problem that occurs frequently after cardiac surgery. Descriptive study. The study sample comprised 102 patients who underwent cardiac surgery. A Descriptive Information Form, Rome III Diagnostic Criteria, Constipation Severity Instrument, Postoperative Defecation Pattern Evaluation Form and Bristol Stool Form Scale were used for data collection and analysis. The Constipation Severity Instrument scores of just over one-third (37·2%) of the patients who were constipated prior to surgery were higher compared to those who were not constipated. Following cardiac surgery, 39·2% of patients developed constipation and 80% of these patients were constipated prior to cardiac surgery. The findings indicate a significantly high relationship between preoperative and postoperative defecation pattern (r=0·71, p<0·001). Preoperative defecation pattern is a determining factor for the development of postoperative constipation for patients undergoing cardiac surgery. During the preoperative period, clinical nurses may evaluate the patients' defecation patterns using valid and reliable scales and follow the defecation of the patients, especially patients with defecation problems, during the postoperative period.

Rectal Hyposensitivity Is Associated With a Defecatory Disorder But Not Delayed Colon Transit Time in a Functional Constipation Population.

The physiological mechanism of functional constipation (FC) includes defecatory disorders and delayed colon transit. About 18% to 68% constipated patients may have rectal hyposensitivity (RH). We performed this study to investigate the association between RH and functional defecatory disorder (FDD) as well as that between RH and delayed colon transit in FC patients.A total of 218 FC patients were enrolled. The constipation severity instrument (CSI) was used to assess constipation symptoms. High-resolution anorectal manometry (HR-ARM), defecography, balloon expulsion tests, and colon transit studies were performed for each patient. RH was defined as 1 or more sensory threshold pressures raised beyond the normal range based on HR-ARM. We investigated the association between RH and constipation symptoms, and the occurrence of FDD and delayed CTT. Ninety FDD patients completed the initial phase of biofeedback treatment (BFT). We investigated the association between RH and the effect of BFT.Totally 122 (56.0%) patients had RH. The total CSI (49.82 ± 1.09 vs 41.25 ± 1.55, P = 0.023) and obstructive defecation subscale scores (23.19 ± 0.69 vs 17.07 ± 0.90, P < 0.001) were significantly higher in RH than in non-RH patients. No significant difference was observed in slow transit symptoms (21.77 ± 0.72 vs 19.90 ± 0.85, P = 0.121) or abdominal pain (6.85 ± 2.61 vs 5.00 ± 1.04, P = 0.380). The frequency of prolonged CTT was not significantly different between RH and non-RH groups (54.1% vs 58.3%, P = 0.403). RH patients rated more occurrence of FDD (72.1% vs 53.1%, P = 0.014) and dysynergic defecation (79.8% vs 50.2%, P = 0.004) than non-RH patients, whereas no differences were seen for inadequate defecatory propulsion (59.2% vs 55.0%, P = 0.589). After BFT, the proportion of “no effect” was significantly higher in the RH group than in the non-RH group (22.4% vs 9.4%, P = 0.010).RH is associated with obstructive defecation symptoms and the occurrence of FDD. Further studies are needed to detect the mechanism of RH's effect on BFT and FC.

The Effect of Abdominal Massage on Constipation and Quality of Life.

This study was a randomized controlled trial aimed to find the impact of abdominal massage application on constipation and quality of life among patients. The sample included 30 intervention (abdominal massage) and 30 control subjects. To collect data, the following were utilized: Patient Information Form, Gastrointestinal Symptom Rating Scale, Constipation Severity Instrument, Bristol Scale Stool Form, Patient Assessment of Constipation Quality of Life (PAC-QOL) Scale, and European Quality of Life Instrument (EQ-5D). The data were collected from among patients in the morning and evening on the fourth, fifth, and sixth days postoperatively. No significant findings were discovered between experimental and control groups in terms of individual characteristics and characteristics that might influence constipation (p > .05). It was found that patients who received abdominal massage application defecated more often following their surgery than patients in the control group, which led to a statistically high level of significant difference between the groups (p ≤ .001). It was also found that the experimental group displayed higher average PAC-QOL and EQ-5D scores on discharge. Findings indicated that abdominal massage applied to patients diagnosed with postoperative constipation reduced symptoms of constipation, decreased time intervals between defecation, and increased quality of life.

Effect of Coexisting Pelvic Floor Disorders on Fecal Incontinence Quality of Life Scores: A Prospective, Survey-Based Study.

The association between an objective measure of fecal incontinence severity and patient-reported quality of life is poorly understood. The purpose of this study was to evaluate patients with various degrees of fecal incontinence to determine whether their quality of life as measured by the Fecal Incontinence Quality of Life Scale is affected by coexisting pelvic floor disorders. This was a prospective, survey-based study. The study was conducted at a tertiary pelvic floor disorders center. Included patients were all of those presenting between January 2007 and March 2014. Survey data were analyzed to determine the association between Fecal Incontinence Severity Index and Fecal Incontinence Quality of Life Scale, as well as scores from the Constipation Severity Instrument, Pelvic Floor Impact Questionnaire, Pelvic Organ Distress Inventory, and Urinary Distress Inventory. A total of 585 patients reported fecal incontinence ranging from none (n = 191) to mild/moderate (n = 159) to severe (n = 235). As expected, patients with severe fecal incontinence have worse scores on all fecal incontinence quality-of-life subscales (lifestyle, coping/behavior, depression/self-perception, and embarrassment) and worse colorectal/anal symptoms than those with mild/moderate or no fecal incontinence (p < 0.0001). Patients with severe fecal incontinence also have worse bladder/urinary symptoms (p ≤ 0.0001). Pelvic organ prolapse and constipation symptoms were similar between groups (p ≥ 0.61). After correcting for baseline differences in patient comorbidities and bladder/urinary symptoms, a significant association persisted between Fecal Incontinence Severity Index and all of the subscales of the fecal incontinence quality-of-life instrument (p < 0.0001). However, urinary distress scores also remained significantly associated with all of the fecal incontinence quality-of-life subscales except for embarrassment after risk adjustment (p < 0.01). Nongeneral population and a lack of patient data on previous medical management of fecal incontinence were limitations of this study. The Fecal Incontinence Quality of Life Scale correlates strongly with instruments measuring both fecal and urinary incontinence. This underscores the importance of quantifying the presence or absence of coexistent urinary leakage in studies where a drop in fecal incontinence quality of life is considered a primary end point.

Differences in Symptom Severity and Quality of Life in Patients With Obstructive Defecation and Colonic Inertia.

Little is known about how obstructive defecation and colonic inertia symptoms contribute to constipation-related quality of life. We sought to characterize the differences in quality of life in patients with severe obstructive defecation and colonic inertia symptoms. This study was a cross-sectional analysis of a prospective database. Patients were enrolled at a single tertiary referral center. We included consecutive adults with severe symptoms of obstructive defecation (n = 115) or colonic inertia (n = 90) as measured by the Constipation Severity Instrument. The primary outcomes measured were the Pelvic Floor Distress Inventory, Constipation-Related Quality of Life instrument, Pelvic Floor Impact Questionnaire, and 12-item Short Form Health Survey. Although physical examination and anorectal physiology testing were similar between groups, patients with severe obstructive defecation symptoms reported worse pain, distress, and constipation-specific quality of life than patients with severe colonic inertia symptoms (all p < 0.001). Specifically, patients with severe obstructive defecation symptoms showed greater quality-of-life impairment related to eating, bathroom habits, and social functioning (all p ≤ 0.01). Furthermore, patients with severe obstructive defecation symptoms had inferior global quality of life on the 12-item Short Form Health Survey physical component score (p = 0.03) and mental component score (p = 0.06). The use of patient self-report instruments resulted in a proportion of patients with incomplete data. Quality of life was impaired in both groups of patients; however, patients with severe obstructive defecation symptoms were affected to a significantly greater extent. The fact that there were no differences in objective findings on physical examination or anorectal physiology studies highlights the importance of assessing quality of life during the evaluation and treatment of constipated patients.

Effect of Connective Tissue Manipulation on Symptoms and Quality of Life in Patients With Chronic Constipation: A Randomized Controlled Trial

ObjectiveThe purpose of this study was to examine the effects of connective tissue manipulation (CTM) on the severity of constipation and health-related quality of life in individuals diagnosed with chronic constipation. MethodsFifty patients with a diagnosis of chronic constipation according to Rome III criteria were recruited and randomized to an intervention (n = 25) or control group (n = 25). The intervention group received CTM in addition to the lifestyle advice, whereas the control group was given only lifestyle advice for constipation. All assessments were performed at baseline and at the end of 4 weeks. The primary outcome measure was the Constipation Severity Instrument. Secondary outcomes included Patient Assessment of Constipation Quality of Life Questionnaire, Bristol Stool Scale, and 7-day bowel diary. Differences between groups were analyzed with t tests, Mann-Whitney U test and χ2 test. ResultsCompared with the control group, subjects in the intervention group reported significantly greater improvement in total and subscale scores of the Constipation Severity Instrument and Patient Assessment of Constipation Quality of Life Questionnaire (P < .05). Based on the results from bowel diaries, the improvements in the number of bowel movements, duration of defecation, stool consistency, and the feeling of incomplete evacuation in the intervention group were also significantly more than the control group (P < .05). ConclusionThis study showed that CTM and lifestyle advice were superior to reducing symptoms of constipation and quality of life compared with lifestyle advice alone for patients with chronic constipation.

The efficacy of education programme for preventing constipation in women

This study was performed to evaluate the efficiency of the education programme for prevention of constipation in women. This study was performed as a pre-test-posttest design. Thirty-five women were included who have constipation problem. Data were collected by questionnaire: Constipation Severity Instrument (CSI), Constipation Visual Analogue Scale (CVAS) and Bristol Stool Chart (BSC). Eight home visits were made for each of the women and they were followed up for 3 months. Participants received an individual education programme that included advice on dietary consumption such as pulpy-fibrous nutrient consumption, fluid intake, an exercise regime and counselling about optimal position to defecate. The subscales of 'Colonic Inertia' and 'Pain', and CSI total mean scores and CVAS mean scores were decreased significantly after education programme (P < 0.05). According to the BSC, 71.5% of the women stated their stool form to be 'sausage-shaped, but lumpy' before the education programme, but after the said programme the percentage had dropped to 17.1%. Education programme given to women who had constipation were determined to have been effective in alleviating constipation. Nurses should develop appropriate and effective strategies to help women prevent constipation.

Exacerbation of Symptom Severity of Pelvic Floor Disorders in Women Who Report a History of Sexual Abuse

To examine the effect of previous sexual abuse or assault (SAA) on symptom severity, quality of life, and physiologic measures in women with fecal incontinence or constipation. A cross-sectional study of a prospectively maintained clinical database. A tertiary referral center for evaluation and physiologic testing for pelvic floor disorders. Women with fecal incontinence or constipation examined during a 6-year period. Symptom severity and quality of life were measured with the Fecal Incontinence Severity Index (FISI), Fecal Incontinence Quality of Life Scale (FIQL), Constipation Severity Instrument (CSI), Constipation-Related Quality of Life measure (CR-QOL), and 12-Item Short Form Health Survey (SF-12). Physiologic variables were ascertained with anorectal manometry, electromyography, and endoanal ultrasonography. Of the 1781 women included, 213 (12.0%) reported SAA. These women were more likely to be white, to report a psychiatric illness, and to have a prior hysterectomy or episiotomy. On bivariate analysis, women with prior SAA had increased symptom severity on the FISI (P = .002) and CSI (P < .001) and diminished quality of life on the FIQL (P < .001), CR-QOL (P = .009), and SF-12 (P = .002 to P = .004). Physiologic variables did not differ significantly between patients with and without prior SAA. A history of SAA significantly alters disease perception in fecal incontinence and constipation, but the disorders do not result from increased physiologic alterations. We must elicit a history of SAA in these patients, because the history may play a role in the discrepancy between symptom reporting and objective measurements and may modify treatment recommendations.

Whole‐body vibration for functional constipation: a single‐centre, single‐blinded, randomized controlled trial

The aim of this trial was to determine whether whole-body vibration (WBV) induced via a noninvasive oscillation platform could improve symptoms and health-related quality of life (HRQOL) in patients with chronic functional constipation. A single-blinded, randomized controlled trial was performed in a single hospital in Taiwan. Patients diagnosed with chronic functional constipation, as per the Rome III diagnostic criteria, were included and randomized to either the WBV treatment or no treatment (control) group. The treatment group received six 15-min sessions of WBV therapy over a 2-week period. Patients received vibrations of 2 mm in amplitude at a frequency of 12 Hz. The primary outcome was whether constipation symptoms improved, assessed by the constipation severity instrument (CSI) and the secondary outcome measure was whether there was an improvement in HRQOL. Whole-body vibration therapy over a 2-week period in patients with chronic functional constipation (n = 14) significantly reduced the total CSI and obstructive defaecation subscale scores compared with control (n = 13). However, WBV did not improve the pain and chronic inertia subscale scores of the CSI or HRQOL. These findings suggest that low-intensity WBV induced via a noninvasive oscillation platform may be an effective therapy for reducing symptom severity in patients with chronic functional constipation.

A randomized controlled trial of anorectal biofeedback for constipation

The purposes of this study were: (1) to examine the efficacy of anorectal biofeedback (AB) for constipation compared to a biofeedback control (BC) treatment and (2) to examine the extent to which self-reported childhood sexual/physical abuse predicted biofeedback outcome. Twenty-one patients with pelvic floor dyssynergia were randomized to either (1) an AB arm, where patients learned to isolate the anal sphincter using an electromyography probe, or (2) a BC arm that controlled for the nonspecific effects of biofeedback, where patients learned to relax trapezius or temporalis muscles with EMG feedback. Both treatments were delivered by registered nurses for six sessions. Prior to randomization and post-treatment, patients completed the validated Constipation Severity Instrument and two measures of quality of life (QOL), the Irritable Bowel Syndrome-QOL, and the SF-36. Generalized estimating equations examined the within-group and between-group differences over time. Pre- and post-treatment data were obtained for six AB and nine BC patients. AB patients' overall constipation severity scores decreased by 35.5% (vs. 15.3%), and their obstructive defecation symptom scores decreased by 37.9% (vs. 19.7%) compared to BC. A similar pattern was shown on the IBS-QOL. On the SF-36 Mental Health Composite (MCS), AB scores improved 28.0% compared to BC scores, which worsened 12.7%. Those without (vs. with) a childhood sexual/physical abuse history showed improvement on the MCS post-biofeedback. While our sample was statistically underpowered, AB produced clinical improvements in constipation severity and QOL.

The Constipation Severity Instrument: A Validated Measure

This study was designed to develop and test the validity and reliability of the Constipation Severity Instrument. Scale development was conducted in two stages: 1) 74 items were generated through a literature review and focus groups of constipated patients and medical providers; and 2) a preliminary instrument was administered to 191 constipated patients and 103 healthy volunteers. Test-retest reliability of the constipated group was assessed (N=90). Content, convergent, divergent, and discriminant validity were evaluated by using other validated measures by performing one-way analysis of variance and Pearson correlations. Exploratory and confirmatory factor analysis revealed three subscales: obstructive defecation, colonic inertia, and pain. Internal consistency (alpha=0.88-0.91) and test-retest reliability (intraclass correlation coefficients=0.84-0.91) were high for all subscales. Constipated patients were grouped by Rome II criteria: functional constipation (22 percent), pelvic floor dyssynergia (15 percent), constipation predominant irritable bowel syndrome (23 percent), and no specific criteria (40 percent). Those with constipation predominant irritable bowel syndrome or pelvic floor dyssynergia scored higher on the Obstructive Defecation and Colonic Inertia subscales than those with functional constipation or no specific criteria (P=0.001-0.058). Subjects with functional constipation had much lower scores on the pain subscale than constipation predominant irritable bowel syndrome, functional constipation, or no specific criteria (P<0.009). The Constipation Severity Instrument subscale and total score correlated very highly with the subscales and total score of the Patient Assessment of Constipation Symptom measure. The Constipation Severity Instrument subscales discriminated well between constipated patients and healthy volunteers (P<0.001) and demonstrated excellent divergent validity. Higher Constipation Severity Instrument scores inversely correlated with general quality of life. The Constipation Severity Instrument is a reliable and valid instrument for assessing constipated patients. Administration of the Constipation Severity Instrument to other constipated patients will further validate its use.
