Effects of Bowel Training and Defecation Posture on Chronic Constipation in Older Adults With Dementia: A Randomized Controlled Trial.

INTRODUCTION: Chronic constipation (CC), which can cause behavioral and psychiatric symptoms of dementia and related caregiver distress, is common in older adults admitted to care facilities with dementia. This study aimed to examine the effect of defecation care on CC and related problems. METHODS: This study compared bowel training and defecation posture intervention (intervention group) with general care (control group) as the treatment of CC among older adults with dementia in 6 long-term care facilities. The primary outcomes were the number of spontaneous bowel movements (SBMs) and complete SBMs. The secondary outcomes were Patient Assessment of Constipation Quality of Life Questionnaire, Constipation Scoring System, constipation symptoms, and Neuropsychiatric Inventory Nursing Home Version scores. The differences were analyzed using 2-way ANOVA with repeated measures. RESULTS: The data of 30 patients (14 in the intervention group, 16 in the control group) were analyzed. Weekly mean complete SBMs increased from 0.53 times at baseline to 1.58 times at 8 weeks in the intervention group compared with a change from 0.56 to 0.43 times in the control group (interaction P < 0.001). The Patient Assessment of Constipation Quality of Life Questionnaire, Constipation Scoring System, behavioral and psychiatric symptoms of dementia, and caregiver distress scores showed significant improvement after 8 weeks of defecation care intervention. DISCUSSION: Defecation care, including bowel training and appropriate defecation posture, is effective for CC among older adults with dementia, improving patient mental health and reducing burden on caregivers.

Effectiveness of electroacupuncture versus prucalopride for women with severe chronic constipation: secondary analysis of a randomized controlled trial.

PURPOSE: Electroacupuncture (EA) is a component alternative therapy for severe chronic constipation (SCC). Women are more vulnerable to SCC and gender might impact the response of patients with functional gastrointestinal disorders to therapy. We performed this secondary analysis to explore the effectiveness and safety of EA compared with prucalopride among women with SCC. METHODS: Based on a multicenter, randomized, noninferiority trial, 446 female patients were randomly assigned to receive 28-session EA (n = 222) over 8 weeks with 24-week follow-up without treatment or to receive prucalopride (n = 224) over 32 consecutive weeks. The primary outcome was the proportion of overall complete spontaneous bowel movements (CSBMs) responders over weeks 1-8, defined as at least three CSBMs per week, and more than an increase of one CSBM from baseline meanwhile for at least 6 weeks during an 8-week treatment period. Secondary outcomes measure sustained CSBM responder, weekly responders, change from baseline in mean weekly CSBMs and SBMs, straining and stool consistency, quality of life, and adverse events (AEs). RESULTS: The proportion of overall responders was 25.23% in the EA group, similar to 25.89% in the prucalopride group, with a between-group difference of - 0.67% (95% CI, - 8.80 to 7.40%; P = 0.872) during an 8-week treatment. In the secondary outcomes, EA and prucalopride groups had no significant difference, except that EA was inferior to prucalopride in improving SBMs. The AEs were less in the EA group than the prucalopride group. CONCLUSION: EA may be a promising and safe treatment for women with SCC; its effect could sustain 24 weeks after treatment stopped.

Long-term outcomes of total colectomy for severe constipation.

AIM: Surgery for constipation is usually reserved for patients with severe and refractory symptoms because of concerns about perioperative morbidity and unpredictable functional outcomes. The aim of this paper is to identify the long-term outcomes of patients who have undergone total colectomy and ileorectal anastomosis for severe constipation. METHOD: Patients who had undergone a total colectomy and ileorectal anastomosis for severe constipation were identified from a prospectively maintained database and sent a postal survey assessing functional symptoms, patient satisfaction and the impact of symptoms on quality of life. Information regarding the surgery, perioperative complications and hospitalizations were also collected. Functional outcomes of the surgery were evaluated with the Gastrointestinal Quality of Life Index, St Marks incontinence score, Wexner continence score, obstructed defaecation syndrome score and Cleveland Clinic constipation score. RESULTS: Seventy-one questionnaires were posted and 32 (45%) patients responded. The mean time since surgery was 15.3 years (range 2.9-30.4 years) Most patients were happy with the surgery. Ongoing symptoms were common, the most frequent of these were abdominal pain, experienced by 23 patients (71.9%), and faecal incontinence, experienced by 17 patients (53%). Fourteen patients (43.8%) required subsequent hospital admission due to bowel obstruction and eight patients (25%%) had subsequent surgery for adhesions. There was an association between patient quality of life and subsequent surgeries. CONCLUSION: Most patients were happy and viewed their life as improved following total colectomy for severe constipation. This is despite a high rate of ongoing functional symptoms.

Laparoscopic modified mesh rectopexy: medium-term results of a novel approach for external rectal prolapse.

AIM: Rectal prolapse is a common and significantly debilitating condition. Surgical correction is usually required. The two most common abdominal approaches are ventral mesh rectopexy and posterior suture rectopexy. Both may be complicated, respectively, by either mesh-related complications or significant postoperative constipation. We report the outcome of a novel rectopexy operation which combines aspects of both the aforementioned approaches, for the treatment of external rectal prolapse (ERP). METHOD: The technique involves laparoscopic partial posterior-lateral rectal mobilization of the rectum with posterior suture fixation to the sacral promontory and placement of an absorbable mesh in the rectovaginal space. Data were collected on postoperative complications, prolapse recurrence, mesh-related complications and the assessment of quality of life. RESULTS: Eighty patients underwent a modified mesh rectopexy for ERP. Seventy-seven were women. The median age was 67.5 years. Almost a third had undergone a previous rectal prolapse repair. Recurrences were seen in 11 (13.8%). No mesh-related complications were seen. Eleven patients reported postoperative constipation. CONCLUSION: The laparoscopic modified mesh rectopexy may be a safe and effective operation for the treatment of ERP.

Modified robotic ventral rectopexy with folded single titanized mesh suspension for the treatment of complex pelvic organ prolapse.

AIM: The incidence of complex pelvic organ prolapse in female patients is about 38%, and this disorder entails social and sexual restrictions. Treatment for this disorder is complex because it can enhance other, latent, problems. The aim of the present study is to describe a new robotic-assisted technique to simultaneously treat prolapses of different compartments with the use of a single titanized polypropylene mesh. METHOD: All patients referred from January 2018 to March 2019 to the Proctologic and Pelvic Floor Clinical Centre who were affected by complex pelvic organ prolapse underwent modified robotic ventral rectopexy with a folded single mesh (RVR-FSM). The anatomical and functional outcomes were respectively evaluated using the Pelvic Organ Prolapse Quantification (POP-Q) grading system and Wexner scores of constipation and incontinence. The satisfaction rate was investigated using a five-point scale (1 = not satisfied to 5 = extremely satisfied). RESULTS: Twenty-two women underwent RVR-FSM with a homogeneous follow-up of 12 months. The mean total operation time was 148 min, without any robot-related or other intraoperative complications. No mesh-related complications occurred. The POP-Q grade improved for every patient, with complete resolution of bulging symptoms in 21 patients (95.4%) at 1 year of follow-up. The Wexner constipation score showed a significant improvement, while the incontinence score slightly improved at 1 year after surgery. CONCLUSION: The use of a single mesh that can be folded was shown to provide significant improvement in functional and anatomical results associated with patient satisfaction. The robotic approach allows surgeons to perform an easier procedure with correct and deep mesh fixation.

Robotic-assisted rectosigmoid resection rectopexy with natural orifice specimen extraction (NOSE): technical notes, short-term results, and functional outcome.

PURPOSE: Rectosigmoid resection rectopexy has been established as an effective therapy for obstructive defecation syndrome. The addition of the NOSE-technique provides an even less invasive approach avoiding minilaparotomy, but can be technically challenging. Application of a robotic platform has been proposed to facilitate the specimen extraction and fashioning of the intracorporeal anastomosis and has been proven to be effective in left-sided colectomies. METHODS: After establishing laparoscopic rectosigmoid-resection-rectopexy with NOSE, we modified our technique by addition of the robotic platform. Whenever robotic capacity was available, elective patients scheduled for rectosigmoid resection rectopexy for obstructive defecation syndrome were operated robotically assisted. Demographic and intraoperative data were prospectively collected. Follow up was assessed using the Wexner constipation score, Wexner incontinence score, and Altomare ODS score. RESULTS: The NOSE-RRR technique was completed in all 31 patients. The mean operative time was 166 min (range 67-230). No conversion was required. The median hospital stay was 5 days (range 3-28). Four patients had minor complications (Clavien I). Two patients were reoperated (Clavien IIIb). Functional scores improved significantly postoperatively. Mean Wexner incontinence score was 7.1 preoperatively, 6.9 after 1 month, and decreased significantly to 3.93 after 3 months (p < 0.001). Mean Altomare ODS score was 17.47 preoperatively and 6.93/5.03 after 1/3 months (p < 0.001). Wexner constipation score (12.83) also showed a significant improvement after 1/3 months (6.97/6.67; p < 0.001). CONCLUSION: NOSE-RRR can be performed safely with a low rate of manageable complications. The technique provides a significant improvement for ODS-Symptoms.

A systematic review examining the impact of blended diets on the gastrointestinal symptoms of people who are enterally fed.

BACKGROUND: Adults and children who are enterally tube-fed can experience adverse gastrointestinal symptoms (GIS). Observational data suggests that blended diets (BD) could mitigate such symptoms, with potential to improve quality of life and clinical outcomes. We present a novel systematic review examining the impact of BD, compared to commercial feeds, on GIS of adults and children who are tube-fed. METHODS: The protocol was registered with PROSPERO (CRD42021261147). Four electronic databases were searched from inception to August 2021. Search terms included 'tube-fed', 'blended diet' and 'formula'. Inclusion criteria were intervention studies comparing blended and commercial feeds using quantitative measures of GIS. Heterogeneity of outcome measures precluded meta-analysis; therefore, a narrative synthesis was conducted. RESULTS: Six papers (n = 219), including two randomised control trials (RCT) and four single arm pre-post studies, were identified. Equal numbers studied in- and out-patients, adults and children. Risk of bias was notable for all studies. Equivocal and insufficient evidence prevented consensus on outcomes of vomiting, gagging, oral intake, bloating and constipation. However, one RCT and two single arm pre-post studies suggest that diarrhoea symptoms may be improved on BD. CONCLUSIONS: Diarrhoea is prevalent in tube-fed populations and associated with adverse outcomes. Improvements in diarrhoea symptoms attributed to BD may be clinically important. Our findings are congruous with the wider observational evidence base, and support recommendations of the British Dietetic Association. BD may pose a viable alternative to commercial formula, and may mitigate symptoms of diarrhoea for adults and children who are tube-fed.

The value of preventing constipation in patients treated with peritoneal dialysis: an advanced practice nursing study / Intérêt de la prévention de la constipation des patients traités par la dialyse péritonéale : une recherche de pratique infirmière avancée

Introduction: In 1989, experts developed the Rome criteria classification coupled with the use of the Bristol scale, to objectify the condition of functional constipation.Background Nowadays, little is documented in the literature about transit disorders in patients with End-Stage Chronic Renal Failure treated with peritoneal dialysis, even though this causes non-negligible complications on the patient’s morbidity, comfort and quality of life. Objective: The main objective of our study was to evaluate the prevalence of constipation in CKD patients. Material and method: We conducted a retrospective multicenter data-driven study. Results: 74 patient records were analyzed. We found a prevalence of constipation of 58 % in patients with CKD. Discussion: Our results showed that the prevalence of constipation is frequent in patients with CKD. It leads to a significant discomfort for the patient, an additional cost in terms of care and technical procedures and a failure of the peritoneal dialysis technique. Conclusion: Thus, the prevention of constipation in CKD patients would be relevant to limit complications and ensure a better quality of life.

Introduction: En 1989, des experts ont mis au point la classification des critères de Rome couplée à l'utilisation de l'échelle de Bristol, afin d'objectiver l'état de constipation fonctionnelle. Contexte: Aujourd'hui, la littérature documente peu les troubles du transit des patients en Insuffisance rénale chronique terminale (IRCT) traités par la Dialyse péritonéale (DP), alors même que cela engendre des complications non négligeables sur la morbidité, le confort et la qualité de vie du patient. Objectif: L'objectif principal de notre étude était d'évaluer la prévalence de la constipation des patients en IRCT. Matériel et méthode: Nous avons réalisé une étude rétrospective multicentrique sur données. Résultats: 74 dossiers patients ont été analysés. Nous avons mis en évidence une prévalence de la constipation de 58 % chez des patients atteints d'une IRCT. Discussion: Nos résultats ont démontré que la prévalence de la constipation est fréquente chez les patients atteints d'une IRCT. Elle entraîne un inconfort notable chez le patient, un surcoût au niveau des soins et des actes techniques, et un échec de la technique de dialyse péritonéale. Conclusion: Ainsi, la prévention de la constipation des patients en IRCT serait pertinente pour limiter les complications et leur assurer une meilleure qualité de vie.

Placebo Response Rates in Trials of Licensed Drugs for Irritable Bowel Syndrome With Constipation or Diarrhea: Meta-analysis.

BACKGROUND & AIMS: There are several licensed drugs for irritable bowel syndrome (IBS) that have proven efficacy in randomized controlled trials (RCTs), but placebo response rates are high. We conducted a systematic review and meta-analysis of licensed drugs to estimate magnitude of placebo response rate according to Food and Drug Administration (FDA)-recommended endpoints and to assess how this varies with stringency of the endpoint used to define response. METHODS: We searched MEDLINE, EMBASE CLASSIC and EMBASE, and the Cochrane central register of controlled trials (through January 2021) to identify RCTs comparing licensed drugs with placebo in adult IBS patients. Studies assessed efficacy according to at least one of composite response, abdominal pain response, or stool response. Data were extracted as intention-to-treat analyses, with dropouts assumed to be treatment failures and pooled using a random-effects model. RESULTS: There were 17 RCTs of licensed drugs versus placebo in IBS with constipation (4603 patients placebo) and 17 trials in IBS with diarrhea (3908 patients placebo). In IBS with constipation, according to FDA criteria, pooled composite, abdominal pain, and stool response rates with placebo over ≥6 of 12 weeks were 18.9%, 34.6%, and 30.1%, respectively. Evaluating response rates over ≥9 of 12 weeks led to placebo response rates of 4.3% for the composite endpoint, 24.5% for abdominal pain, and 7.7% for stool. In IBS with diarrhea, pooled placebo response rates according to FDA criteria were 16.2% for the composite endpoint, 40.2% for abdominal pain, and 16.2% for stool. Increasing the threshold used to define abdominal pain response from ≥30% improvement to ≥40% or ≥50% led to lower placebo response rates of 34.5% and 23.4%. CONCLUSIONS: Future RCTs should adhere to current FDA-recommended endpoints for IBS because these lead to lower placebo response rates. However, consideration should be given to further refining some of these to better differentiate between active drug and placebo.

Effective Communication Strategies and Tools for Improving Treatment Outcomes in Patients With Chronic Idiopathic Constipation and Irritable Bowel Syndrome With Constipation.

Patients with chronic idiopathic constipation and irritable bowel syndrome with constipation experience an array of gastrointestinal symptoms. Given the subjective nature of these disorders, patient self-reporting is critical to diagnosis and monitoring response to therapy. Unfortunately, many patients are reluctant to discuss bowel symptoms with their healthcare providers. Differences in sex, health literacy, and age can influence symptom reporting. Negative patient-physician relationships and dissatisfaction with care lead patients to seek alternative treatments, switch healthcare providers, or discontinue care. Thus, adopting a patient-centered communication style can help create a shared understanding of patients' symptoms, achieve accurate symptom reporting, expedite diagnosis, and facilitate appropriate treatment plans. Currently, there are multiple symptom and quality-of-life scales available to assist healthcare providers in this endeavor. These scales also allow for the monitoring of constipation-related symptoms and symptom severity. When using patient self-assessments to measure treatment responses, scale selection may depend on the number of symptoms being assessed, the duration and frequency of assessments, and patients' comprehension and language skills.

Systematic review and meta-analysis of the outcome of puborectalis division in the treatment of anismus.

AIM: Anismus is a common cause of obstructed defaecation syndrome (ODS). The aim of the present review is to assess the efficacy and safety of puborectalis muscle (PRM) division in the treatment of anismus. METHOD: PubMed, Scopus, Web of Science and the Cochrane Library were searched for studies that assessed the outcome of PRM division in the treatment of anismus. The main outcome measures were subjective improvement in ODS, decrease in the Wexner constipation score and ODS score, and complications, namely faecal incontinence (FI). RESULTS: Ten studies (204 patients, 63.7% male) were included. The weighted mean rate of initial subjective improvement across randomized trials was 97.6% (95% CI 94%-100%) and across nonrandomized studies it was 63.1 (95% CI 39.3%-87%). The weighted mean rate of 12-month improvement across randomized trials was 64.9% (95% CI 53.3%-76.4%) and across nonrandomized studies it was 55.9% (95% CI 30.8%-81%). The weighted mean rate of FI across randomized trials was 12.1% (95% CI 4.2%-20%) and across nonrandomized studies it was 10.4% (95% CI 1.6%-19.3%). Male sex and unilateral PRM division were significantly associated with recurrence of symptoms after PRM division. Bilateral PRM division, posterior division, complete division and concomitant sphincterotomy were significantly associated with FI after PRM division. CONCLUSIONS: The use of PRM division for treatment of anismus was followed by some initial improvement in ODS symptoms which decreased to <60% 12 months after PRM division. The mean rate of FI after PRM division, namely 10%-12%, is a limitation of the technique. Further well-designed trials are needed to verify the outcome of PRM division in the treatment of anismus.

Conservative versus Radical Surgery for Women with Deep Infiltrating Endometriosis: Systematic Review and Meta-analysis of Bowel Function.

OBJECTIVE: To assess bowel function in women with deep infiltrating endometriosis according to surgical approach (radical vs conservative). DATA SOURCES: Five databases were searched from 1970 to September 2021 to retrieve studies comparing radical (colorectal segmental resection) and conservative (shaving or discoid excision) surgery for bowel function in women with deep infiltrating endometriosis. METHODS OF STUDY SELECTION: No language restriction was applied. Two reviewers extracted and combined data from the included studies, applying a meta-analytic model with random effects in all calculations. Results are expressed in risk ratio (RR) with 95% confidence interval (CI). Assessment of risk of bias and quality of evidence was performed by the Newcastle-Ottawa and Grading of Recommendations, Assessment, Development and Evaluation, respectively. TABULATION, INTEGRATION, AND RESULTS: We included 13 studies in our meta-analysis, and most of them were of nonrandomized design. Conservative surgery had fewer events of constipation and frequent bowel movements when compared with radical surgery (RR, 2.31; 95% CI, 1.21-4.43; I2 = 0%; 3 studies; RR, 2.80; 95% CI 1.17-6.75; I2 = 0%; 2 studies, respectively). Defecation pain, anal incontinence loss, minor and major lower anterior resection syndrome, and Clavien-Dindo complications grade I to IV showed no statistically significant difference between surgeries. Grading of Recommendations, Assessment, Development and Evaluation assessment was low to very low for all outcomes. CONCLUSION: Conservative surgery (shaving or discoid excision) presented fewer events of constipation and frequent bowel movements than colorectal segmental resection. There was a very low quality of evidence to provide recommendations regarding bowel function.

Time trend in the surgical management of obstructed defecation syndrome: a multicenter experience on behalf of the Italian Society of Colorectal Surgery (SICCR).

BACKGROUND: Surgical management of obstructed defecation syndrome (ODS) is challenging, with several surgical options showing inconsistent functional results over time. The aim of this study was to evaluate the trend in surgical management of ODS in a 10-year timeframe across Italian referral centers. METHODS: Surgeons from referral centers for the management of pelvic floor disorders and affiliated to the Italian Society of Colorectal Surgery provided data on the yearly volume of procedures for ODS from 2010 to 2019. Six common clinical scenarios of ODS were captured, including details on patient's anal sphincter function and presence of rectocele and/or rectal intussusception. Perineal repair, ventral rectopexy (VRP), transanal repair (internal Delorme), stapled transanal rectal resection (STARR), Contour Transtar, and transvaginal repair were considered in each clinical scenario. RESULTS: Twenty-five centers were included providing data on 2943 surgical patients. Procedure volumes ranged from 10-20 (54%) to 21-50 (46%) per year across centers. The most performed techniques in patients with good sphincter function were transanal repair for isolated rectocele (243/716 [34%]), transanal repair for isolated rectal intussusception (287/677 [42%]) and VRP for combined abnormalities (464/976 [48%]). When considering poor sphincter function, these were perineal repair (112/194 [57.8%]) for isolated rectocele, and VRP for the other two scenarios (60/120 [50%] and 97/260 [37%], respectively). The use of STARR and Contour Transtar decreased over time in patients with impaired sphincter function. CONCLUSIONS: The complexity of ODS treatment is confirmed by the variety of clinical scenarios that can occur and by the changing trend of surgical management over the last 10 years.

Predictive factors for functional failure of ventral mesh rectopexy in the treatment of rectal prolapse and obstructed defecation.

BACKGROUND: Ventral mesh rectopexy (VMR) is widely accepted for the treatment of rectal prolapse or obstructed defecation. However, despite good anatomical results, the improvement of functional symptoms (constipation or incontinence) cannot always be obtained and in some cases these symptoms may even worsen. The aim of the present study was to identify possible predictors of functional failure after VMR. METHODS: Data of all consecutive patients who had VMR for the treatment of rectal prolapse and/or obstructed defecation between January 2017 and December 2020 in three different pelvic floor surgical centres in Italy were analysed to identify possible predictors of functional failure, intended as persistence, worsening or new onset of constipation or faecal incontinence. Symptom severity was assessed pre- and postoperatively with the Wexner Constipation score and Obstructed Defecation Syndrome score. Quality of life was assessed, also before and after treatment, with the Patients Assessment of Constipation Quality of Life questionnaire, the Pelvic Floor Disability Index and the Pelvic Floor Impact Questionnaire. Faecal incontinence was evaluated with the Cleveland Clinic Incontinence Score. The functional outcomes before and after surgery were compared. RESULTS: Sixty-one patients were included (M:F ratio 3:60, median age 64 years [range 33-88 years]). Forty-two patients (68.9%) had obstructed defecation syndrome, 12(19.7%) had faecal incontinence and 7 patients (11.5%) had both. A statistically significant reduction between pre- and postoperative Obstructed Defecation Syndrome and Wexner scores was reported (p < 0.0001 in both cases). However, the postoperative presence of constipation occurred in 22 patients (36.1%) (this included 3 cases of new-onset constipation). The presence of redundant colon and the pre-existent constipation were associated with an increased risk of persistence of constipation postoperatively or new-onset constipation (p = 0.004 and p < 0.0001, respectively). The use of postoperative pelvic floor rehabilitation (p = 0.034) may reduce the risk of postoperative constipation. CONCLUSIONS: VMR is a safe and effective intervention for correcting the anatomical defect of rectal prolapse. The degree of prolapse, the presence of dolichocolon and pre-existing constipation are risk factors for the persistence or new onset of postoperative constipation. Postoperative rehabilitation treatment may reduce this risk.

Lessons from recent medical history: an obsolete anti-reflux device in an older patient with variable gastrointestinal symptoms.

A frail 93-year-old lady presented with delirium, on a background of heart failure, cerebrovascular disease, constipation and osteoporosis. A computed tomography (CT) pulmonary angiography, undertaken due to persistent hypoxia, identified no pathology aside from an unusual appearance of the left hypochondrium, necessitating further elucidation with CT abdomen. This unexpectedly reported the presence of a gastric band, leading us to consider possible misidentification. Perusing her General Practitioner (GP) records demonstrated that she underwent surgical insertion of an Angelchik prosthesis in 1984. Angelchik prostheses were anti-reflux devices used for a short period, before falling from favour due to increasing evidence around late developing complications. A collateral history from family revealed that this patient had experienced multiple longstanding symptoms including bloating, reflux and constipation, potentially linked to her prosthesis, a previously unestablished link.

Improvement in Outlet Obstructive Constipation Symptoms After Vaginal Stent Treatment for Rectocele.

Objective. The objective is to determine the possible improvement in outlet obstructive constipation symptoms after vaginal stent treatment for rectocele. Methods. Female patients with rectocele (n = 156) accompanied with outlet obstructive constipation were selected in this study. Longo's obstructed defecation syndrome (ODS) questionnaire, rectoanal pressures, and rectal balloon expulsion (BET) were evaluated at baseline, 1 month follow-up, and 6 months follow-up. Moreover, the side effects and the potential reasons for giving up treatment were also detected. Results. Vaginal stent significantly decreased the straining intensity, shortened the straining extensity time, decreased the use of laxatives, and alleviated the symptoms of incomplete evacuation (P < .05). The vaginal stent also increased the rectal pressure and shortened the balloon expulsion time (P < .05). Conclusions. As an effective, feasible, and safe procedure, the vaginal stent can be recommended as a treatment of choice for rectocele combined with outlet obstructive constipation.

Utility of the Mansoura Numeroalphabetic Constipation Score in detection of obstructed defaecation syndrome and prediction of the outcome of treatment.

AIM: Thorough assessment of obstructed defaecation syndrome (ODS) is imperative for the selection of treatment options. The present study aimed to examine the utility of the Mansoura Numeroalphabetic Constipation Score (MNCS) in distinguishing patients with ODS from healthy control subjects and in predicting the outcome of treatment of ODS. METHODS: Patients with ODS associated with anterior rectocele and/or rectoanal intussusception were assessed with the MNCS at the first visit to the clinic. All patients were offered conservative treatment for 3 months and patients who improved were continued on conservative treatment for six more months while patients who failed were treated surgically. The MNCS was reassessed at the end of follow-up in both groups. A cohort of healthy controls was compared to ODS patients with regard to age, sex and baseline MNCS. RESULTS: In all, 124 ODS patients and 53 healthy controls were included. The ODS patients had a significantly higher baseline MNCS than controls (9.5 ± 1.5 vs 0.76 ± 0.71, P < 0.0001). Forty of 124 patients improved after conservative management and showed a significant decrease in MNCS (6.9 ± 1.08 to 3.1 ± 1.2, P < 0.0001). Eighty-four (67.8%) patients failed to respond to conservative measures and were surgically treated, 77 (91.6%) of whom showed significant improvement in symptoms postoperatively while seven (8.4%) failed to improve; the difference in postoperative MNCS between the two groups was significant. CONCLUSION: The MNCS successfully distinguished ODS patients from controls and was able to predict the outcome of ODS treatment.

Bowel preparation prior to minimally invasive sacrocolpopexy: a randomized controlled trial.

INTRODUCTION AND HYPOTHESIS: The objective was to determine if a bowel preparation prior to minimally invasive sacrocolpopexy (MIS) influences post-operative constipation symptoms. We hypothesized that women who underwent a bowel preparation would have an improvement in post-operative defecatory function. METHODS: In this randomized controlled trial, women undergoing MIS received a pre-operative bowel preparation or no bowel preparation. Our primary outcome was post-operative constipation measured by the Patient Assessment of Constipation Symptoms (PAC-SYM) 2 weeks post-operatively. Secondary outcomes included surgeon's perception of case difficulty. Both intention-to-treat (ITT) and per-protocol analyses (PPA) were performed. Analyses were carried out using t test, Fisher's exact test, the Wilcoxon test and the Chi-squared test. RESULTS: Of 105 enrolled women, 95 completed follow-up (43 preparation and 52 no preparation). Baseline characteristics and rates of complications were similar. No differences were noted on ITT. The post-operative abdominal PAC-SYM subscale was closer to baseline for women who received a bowel preparation on PPA (change in score 0.74 vs 1.08, p = 0.045). Women who underwent a preparation were less likely to report strain (6.0% vs 26.7%, p = 0.009) or type 1 Bristol stool on their first post-operative bowel movement (4.3% vs 17.5%, p = 0.047). Surgeons were more likely to rate the complexity of the case as "more difficult than average" (54.4% vs 40.1%, p = 0.027) in those without a bowel preparation. CONCLUSIONS: Although there was no difference in ITT analysis, women who underwent a bowel preparation prior to MIS demonstrated benefit to post-operative defecatory function with a corresponding improvement in surgeon's perception of case complexity.

Free large sized intra-abdominal endometrioma in a postmenopausal woman: a case report.

BACKGROUND: Endometriosis is an estrogen-dependent disease defined by the presence of endometrial glands and stroma out of the uterine cavity. Its prevalence is estimated to be 2-10% in reproductive aged women. Endometriosis occurrence is estimated to be 2.55% in postmenopausal patients due to the decreased levels of estrogen. Endometriosis can present in three different forms: superficial peritoneal implants, ovarian endometriomas, and deep infiltrating endometriosis. Ovarian endometriomas are the most common form of endometriosis. Even though endometriomas have been encountered in various localizations, a free abdominal endometrioma was only reported once in a premenopausal patient. Here, we are reporting the first case of a free large endometrioma in a postmenopausal patient. CASE PRESENTATION: A 67-year-old woman presented to the emergency department at our university hospital complaining of constipation and right flank pain. She suffered from uncontrolled primary hypertension and type 2 diabetes mellitus. On presentation, she was afebrile, hypertensive, and tachycardic. An abdominal CT scan revealed a large cystic mass measuring 17 × 26 cm in the anterior-posterior and transverse diameters respectively. The cyst caused bowel obstruction and right sided hydronephrosis. The patient underwent laparotomy and during the surgical exploration a large abdominal cyst adhered to the greater omentum was found. The cyst received plenteous blood supply from the greater omentum. The uterus and both ovaries were completely normal and didn't have any connection to the cyst. An en-bloc cystectomy was performed successfully. The final histopathology report confirmed an abdominal endometrioma. The patient had an uneventful postoperative recovery. CONCLUSIONS: Endometriomas might reach large sizes regardless of their location or the patient's age. The close relation of free abdominal endometriomas with the greater omentum suggests that these were developed from endometriotic omental implants. Endometrioma is rare in postmenopausal women. However, it should be considered as a possible differential diagnosis at any age.

Parkinson's disease and the non-motor symptoms: hyposmia, weight loss, osteosarcopenia.

Non-motor symptoms (NMSs) are common in Parkinson's disease (PD) and can precede, sometimes for several years. NMSs include, other than gastrointestinal symptoms like constipation and dysphagia, also hyposmia, weight loss and osteosarcopenia. These three NMSs seem to be inter-related and affect patients' health and quality of life. Unfortunately, patients with these symptoms usually are not initially seen by a neurologist, and by the time they are consulted, nearly ~ 80% of the dopaminergic neurons in the substantia nigra have died. To date, no guidelines exist for screening, assessment and management of NMSs in general. A better understanding of these specific NMSs, likely in the context of others, will make it possible to approach and optimise the treatment of the motor symptoms thereby enhancing the welfare of PD patients. Identifying the NMSs could be very helpful, and among them, hyposmia, weight loss and osteosarcopenia may play an important role in solving the limitations in the diagnosis of PD. A strict collaboration between general practitioners, clinicians, geriatricians and neurologists can be one approach towards the diagnosis of pre-PD. Waiting until the motor symptoms develop and the patient is finally visited by the neurologist could be too late, considering the catastrophic prognosis of the disease.
