He N, Sheng K, Li G, Zhang S. The causal relationship between gut microbiota and constipation: a two-sample Mendelian randomization study. BMC Gastroenterol 2024; 24:271. [PMID: 39160466 PMCID: PMC11331768 DOI: 10.1186/s12876-024-03306-8] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/16/2024] [Accepted: 06/25/2024] [Indexed: 08/21/2024] Open
Abstract
BACKGROUND Constipation is one of the most common gastrointestinal disorders afflicting the population, with recent observational studies implicating dysfunction of the gut microbiota in constipation. Despite observational studies indicating a relationship, a clear causality remains unclear. This study aims to use two-sample Mendelian randomization (MR) to establish a clearer causal relationship between the two. METHODS A two-sample Mendelian randomization (MR) study was performed using the gut microbiota summary Genome-Wide Association Studies (GWAS) statistics from MiBioGen consortium (n = 13,266) and constipation GWAS summary statistics from the IEU OpenGWAS database. The causality between gut microbiota and constipation is primarily analyzed using the inverse-variance weighted (IVW) method and reinforced by an additional four methods, including MR-Egger, Weighted Median, Simple Mode, and Weighted Mode. Finally, funnel plot, heterogeneity test, horizontal pleiotropy test, and leave-one-out test were used to evaluate the reliability of MR results. RESULTS IVW estimates suggested that the bacterial species Anaerotruncus, Butyricimonas, and Hungatella were causally associated with constipation. The odds ratio (OR) values of Anaerotruncus, Butyricimonas, and Hungatella were 1.08 (95% CI = 1.02-1.13; P = 0.007), 1.07 (95% CI = 1.01-1.13; P = 0.015), 1.03 (95% CI = 1.00-1.06; P = 0.037) respectively. Meanwhile, Ruminiclostridium 9 and Intestinibacter have been shown to be associated with a reduced risk of constipation. The OR of Ruminiclostridium 9 = 0.75(95% CI = 0.73-0.78, P < 0.001 and Intestinibacter of OR = 0.89 (95% CI = 0.86-0.93, P < 0.001). Furthermore, validation by funnel plot, heterogeneity test, and horizontal pleiotropy test showed that MR results were reliable. CONCLUSION This is the first Mendelian randomization study to explore the causalities between specific gut microbiota taxa and constipation, and as such may be useful in providing insights into the unclear pathology of constipation which can in turn aid in the search for prevention and treatment.

Early safety and efficiency outcomes of a novel interdisciplinary laparoscopic resection rectopexy combined with sacrocolpopexy for women with obstructive defecation syndrome and pelvic organ prolapse: a single center study. BMC Surg 2024; 24:185. [PMID: 38877450 PMCID: PMC11177501 DOI: 10.1186/s12893-024-02474-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/10/2023] [Accepted: 06/06/2024] [Indexed: 06/16/2024] Open
Abstract
BACKGROUND Obstructive defecation syndrome (ODS) defines a disturbed defecation process frequently associated with pelvic organ prolapse (POP) in women that substantially compromises quality of life. Conservative management offers limited relief and a surgical intervention may be required. This is characterized by individual approaches. AIM OF THE STUDY: This retrospective single center study evaluated the surgical and clinical short-term outcome of a novel interdisciplinary laparoscopic resection rectopexy (L-RRP) with mesh- sacrocolpopexy (L-SCP) for women suffering from ODS and POP. METHODS The study participants underwent surgery in an interdisciplinary laparoscopic approach. Safety was the primary endpoint, assessed via postoperative morbidity classified by Clavien-Dindo scale. Secondary outcomes included evaluation of bowel function, fecal and urinary incontinence and pelvic organ prolapse status at 12 months follow-up. Additionally, a biological mesh (BM) was offered to women, who asked for an alternative to synthetic mesh material (SM). RESULTS Of the 44 consecutive patients requiring surgery for ODS and POP, 36 patients underwent the interdisciplinary surgical approach; 28 patients with SM and 8 patients with BM. In total 5 complications occurred, four of them were classified as minor. One minor complication was observed in the BM group. One anastomotic leakage occurred in the SM group. The two ODS scores, the bowel dysfunction score, and the incontinence score improved significantly (p = 0.006, p = 0.003, p < 0.001, and p = 0.0035, respectively). Pelvic floor anatomy was fully restored (POP-Q 0) for 29 (80%) patients after surgery. 17 patients (47%) suffered from urinary incontinence before surgery, which was restored in 13 patients (76.5%). CONCLUSIONS The interdisciplinary approach with L-RRP and L-SCP and the use of a BM in a small subgroup were technically feasible, safe, and effective in this single center setting. The study's retrospective design, the small sample size and the lack of comparators limit the generalizability of the findings requiring future randomized trials.

Abstract
Background Obstructive defecation syndrome (ODS) is frequently associated with pelvic organ prolapse (POP) and compromises the quality of life in affected patients. In cases conservative treatment fails surgical therapy is required. Objectives The video case study combines a laparoscopic resection rectopexy (RRP) with a mesh sacrocolpopexy (SCP) in an interdisciplinary surgical approach. Materials and Methods In this video an 86-year-old woman with ODS and POP, suffering from a dolichocolon with rectal intussusception, an apical prolapse after total hysterectomy 1990, and occasional stress urinary incontinence underwent interdisciplinary laparoscopic surgery. A tubular anterior rectal and sigmoid resection with suture rectopexy as in a resection rectopexy (RRP) was combined with a sacrocolpopexy (SCP) using a synthetic mesh. Main outcome measures Surgical outcome including postoperative morbidity, functional bowel evacuation, and POP reconstitution as in POP-Q score after surgery were documented. Results No intra- or postoperative complications occurred. At 6 months follow-up clinical outcomes for ODS, bowel dysfunction, and faecal control were improved. Anatomical outcome for POP and stress urinary incontinence symptoms were corrected. Conclusions We report a promising interdisciplinary surgical approach as a single treatment option for the complex medical condition of women suffering from ODS and POP combining laparoscopic RRP with SCP. This surgical approach proved to be feasible, safe, and effective.

Abstract
Juvenile polyps (JPs) are the most common polyps in pediatric patients. We present the case of an 18-year-old male patient with a giant solitary JP resembling solitary rectal ulcer syndrome (SRUS). The presenting history was rectal bleeding and symptoms of obstructed defecation syndrome. Colonoscopy revealed a polypoidal mass at the anorectal junction, with biopsy-confirmed SRUS. The symptoms worsened, and a protruding mass from the anus caused fecal incontinence. Pelvic magnetic resonance imaging showed a huge pedunculated mass occupying the low rectum with local compression of the urinary bladder. Transanal excision of the anal tumor was performed due to bleeding. A histopathological examination showed a JP with high-grade dysplasia. A histological examination to differentiate JPs and SRUS could be challenging based on a superficial forceps biopsy. Therefore, an excision biopsy is usually warranted with the understanding that adenomatous or malignant transformation is found in 5.6% to 12% of all JPs.

Abstract
Constipation is a prevalent clinical ailment of the gastrointestinal system, yet its pathogenesis remains ambiguous. Despite the availability of numerous treatment modalities, they are insufficient in resolving the issue for patients. This work conducted a comprehensive review of the existing literature pertaining to the utilization of natural products for the treatment of constipation, with a focus on the efficacy of natural products in treating constipation, and to provide a comprehensive summary of their underlying mechanisms of action. Upon conducting a thorough review of the extant literature, we found that natural products can effectively treat constipation as modern synthetic drugs and compounded drugs with acetylcholinesterase (AChE) effects, rich in fiber and mucus, and the effects of increasing the tension of the ileum and gastrointestinal tract muscle, mediating signaling pathways, cytokine, excitability of the smooth muscle of the gastrointestinal tract, and regulating the homeostasis of intestinal flora. However, there is a wide variety of natural products, and there are still relatively few studies; the composition of natural products is complex, and the mechanism of action of natural products cannot be clarified. In the future, we need to further improve the detailed mechanism of natural products for the treatment of constipation.

Abstract
BACKGROUND Constipation is a common gastrointestinal issue with significant economic implications. Its prevalence varies globally, and it can have acute or chronic forms with primary or secondary causes. The pathophysiology of constipation is influenced by various factors. While previous studies have reported varying levels of awareness of constipation and its complications in different regions of Saudi Arabia, no comprehensive research has assessed such awareness among the general population. This study, thus, aimed to assess awareness of constipation and its complications among the public in Saudi Arabia. METHODOLOGY A descriptive cross-sectional study was conducted in Saudi Arabia on individuals aged 18 and above, excluding healthcare workers. Data were collected using a validated survey distributed online between September 2023 and November 2023. RESULTS A total of 1,139 participants were included in the study, predominantly female 739 (64.9%), and most of the participants 595 (52.2%) aged between 19 and 30 years, The majority of participants 850 (74.6%) had bachelor's degree. Regarding the source of medical information, 312 (27.4%) of the participants stated that they obtained medical information from social media. Additionally, 811 (71.2%) of participants reported experiencing constipation. Overall, 847 (74.4%) of participants demonstrated a good level of awareness of constipation, while 292 (25.6%) had a poor level of awareness. Significant associations were found between awareness level and age, city of residence, and occupation. CONCLUSION Most adults in Saudi Arabia have a high level of awareness of constipation and its complications.

Abstract
Fecobionics is a novel integrated technology for assessment of anorectal function. It is a defecatory test with simultaneous measurements of pressures, orientation, and device angle (a proxy of the anorectal angle). Furthermore, the latest Fecobionics prototypes measure diameters (shape) using impedance planimetry during evacuation of the device. The simultaneous measurement of multiple variables in the integrated test allows new metrics to be developed including more advanced novel defecation indices, enabling mechanistic insight in the defecation process at an unprecedented level in patients with anorectal disorders including patients suffering from obstructed defecation, fecal incontinence, and low anterior resection syndrome. The device has the consistency and shape of a normal stool (type 3-4 on the Bristol Stool Form Scale). Fecobionics has been validated on the bench and in animal studies and used in clinical trials to study defecation phenotypes in normal human subjects and patients with obstructed defecation, fecal incontinence, and low anterior resection syndrome after rectal cancer surgery. Subtypes have been defined, especially of patients with obstructed defecation. Furthermore, Fecobionics has been used to monitor biofeedback therapy in patients with fecal incontinence to predict the outcome of the therapy (responder versus non-responder). Most Fecobionics studies showed a closer correlation to symptoms as compared to current technologies for anorectal assessment. The present article outlines previous and ongoing work, and perspectives for future studies in proctology, including in physiological assessment of function, diagnostics, monitoring of therapy, and as a tool for biofeedback therapy.

Abstract
BACKGROUND AND OBJECTIVES obstructed defecation syndrome (ODS) is a common but underestimated condition that may affect the outcomes after hemorrhoidectomy. Therefore, the aim of this study was to determine the prevalence of obstructed defecation syndrome (ODS) among patients who underwent hemorrhoidectomy and to assess the correlation between preoperative constipation score and postoperative patients' satisfaction. MATERIALS AND METHODS This prospective study included adult patients who underwent hemorrhoidectomy for 3rd and 4th-grade hemorrhoidal diseases. All participant patients underwent an assessment of functional OD severity by the Agachan-Wexner Constipation Scoring System. All patients were subjected to conventional hemorrhoidectomy. At 6 months postoperatively, patients were assessed again for their constipation score and postoperative patients' satisfaction. RESULTS The study included 120 patients (62 males and 58 females) with a mean age of 38.7 ± 12.1 years. About one-quarter of patients (24.2%) had obstructed defecation (constipation score ≥12). ODS (constipation score ≥12) was found to be significantly more among older patients, female patients, especially those with multiple pregnancies and multiple labors, and those with perineal descent. The postoperative constipation score (5.6 ± 3.3 mean ± SD) showed significant improvement (p = 0.001) compared to (9.3 ± 3.9 mean ± SD) preoperatively. Postoperative patients' satisfaction (mean 12.3 ± 3.0) at 6 months had a negative correlation with preoperative total constipation score (r = -0.035, p = 0.702). CONCLUSIONS The prevalence of obstructed defecation among patients with hemorrhoids was higher than reported among the general population. High preoperative constipation scores had a negative correlation with postoperative patients' satisfaction. Routine preoperative measurement of ODS can allow the detection of this particular group of patients who require a more physical and psychological evaluation, in addition to special preoperative counseling.

Abstract
Background
Functional obstructed defecation is a common anorectal problem among adult population. The objective was to compare the short-term efficacy of biofeedback pelvic floor muscle training versus transcutaneous posterior tibial nerve electrostimulation in treatment of patients with functional obstructed defecation.
Results
There were 41 patients completed the study. There were no statistical significant differences between biofeedback pelvic floor muscle training group and transcutaneous posterior tibial nerve electrostimulation group regarding different clinical characteristics, as well as, electrophysiological findings. There was statistically significant reduction in all outcome measures after intervention in both groups. The primary outcome measure was Modified obstructed defecation score. Secondary outcome measures were Patient Assessment of Constipation-Quality of Life questionnaire, time of toileting, and maximum anal pressure during straining to evacuate. No significant differences were present between both groups regarding different outcome measures in the pretreatment and post-treatment assessments. Successful outcome was reported in 81% of patients in biofeedback pelvic floor muscle training group in comparison to 40% of patients in the posterior tibial nerve electrostimulation group according to the Modified obstructed defecation score which was the primary outcome measure.
Conclusions
Both biofeedback pelvic floor muscle training and posterior tibial nerve electrostimulation are considered effective methods in the treatment of functional obstructed defecation. However, biofeedback pelvic floor muscle training seems to be more effective and superior in comparison to posterior tibial nerve electrostimulation. Posterior tibial nerve electrostimulation could be combined with biofeedback pelvic floor muscle training or considered as a second line therapy after failure of biofeedback pelvic floor muscle training.

Abstract
Constipation is very pervasive all over the world. It is a common multifactorial gastrointestinal disease, and its etiology and pathomechanism are not completely clear. Now, increasing evidence shows that intestinal flora is closely related to constipation. Intestinal flora is the largest microbiota in the human body and has powerful metabolic functions. Intestinal flora can produce a variety of metabolites, such as bile acids, short-chain fatty acids, tryptophan metabolites, and methane, which have important effects on intestinal motility and secretion. The host can also monitor the intestinal flora and regulate gut dysbacteriosis in constipation. To explore the relationship between intestinal flora and host, the combination of multiomics technology has become the powerful and effective method. Furthermore, the homeostasis restoration of intestinal flora also provides a new strategy for the treatment of constipation. This review aims to explore the interaction between intestinal flora and host in constipation, which contributes to disclose the pathogenesis of constipation and the development of novel drugs for the treatment of constipation from the perspective of intestinal flora. KEY POINTS: • This review highlights the regulation of gut microbiota on the intestinal motility and secretion of host. • The current review gives an insight into the role of the host on the recognition and regulation of intestinal ecology under constipation. • The article also introduces some novel methods of current gut microbiota research and gut microbiota-based constipation therapies.

Abstract
Obstructed defecation syndrome (ODS) is a form of constipation that influences the quality of life in most patients and is an important health care issue. In 2004 Longo introduced a minimal invasive trans-anal approach known as Stapled Trans-Anal Rectal Resection (STARR) in order to correct mechanical disorders such as rectocele or rectal intussusception, two conditions present in more than 90% of patients with ODS. Considering the lack of a common view around ODS and STARR procedure. the aim of our study is to review the literature about preoperative assessment, operative features and outcomes of the STARR technique for the treatment of ODS. We performed a systematic search of literature, between January 2008 and December 2020 and 24 studies were included in this review. The total number of patients treated with STARR procedure was 4,464. In conclusion STARR surgical procedure has been proven to be safe and effective in treating symptoms of ODS and improving patients Quality of Life (QoL) and should be taken in consideration in the context of a holistic and multi modal approach to this complex condition. International guidelines are needed in order to optimize the diagnostic and therapeutic process and to improve outcomes.

[PMID: 35129656 DOI: 10.1007/s00253-022-11813-5] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2021] [Revised: 01/27/2022] [Accepted: 01/29/2022] [Indexed: 12/17/2022]
Abstract
Rhubarb, a traditional herb, has been used in clinical practice for hundreds of years to cure constipation, but its mechanism is still not clear enough. Currently, growing evidence suggests that intestinal flora might be a potential target for the treatment of constipation. Thus, the aim of this study was to clarify the laxative effect of rhubarb via systematically analyzing the metagenome and metabolome of the gut microbiota. In this study, the laxative effects of rhubarb were investigated by loperamide-induced constipation in rats. The gut microbiota was determined by high-throughput sequencing of 16S rRNA gene. Ultra-high performance liquid chromatography-quadrupole time-of-flight mass spectrometry was used for fecal metabolomics analysis. The data showed that rhubarb could significantly shorten gastrointestinal transit time, increase fecal water content and defecation frequency, improve gastrointestinal hormone disruption, and protect the colon mucus layer. Analysis of 16S rRNA gene sequencing indicated that rhubarb could improve the disorder of intestinal microbiota in constipated rats. For example, beneficial bacteria such as Ligilactobacillus, Limosilalactobacillus, and Prevotellaceae UCG-001 were remarkably increased, and pathogens such as Escherichia-Shigella were significantly decreased after rhubarb treatment. Additionally, the fecal metabolic profiles of constipated rats were improved by rhubarb. After rhubarb treatment, metabolites such as chenodeoxycholic acid, cholic acid, prostaglandin F2α, and α-linolenic acid were markedly increased in constipation rats; in contrast, the metabolites such as lithocholic acid, calcidiol, and 10-hydroxystearic acid were notably reduced in constipation rats. Moreover, correlation analysis indicated a close relationship between intestinal flora, fecal metabolites, and biochemical indices associated with constipation. In conclusion, the amelioration of rhubarb in constipation might modulate the intestinal microflora and its metabolism. Moreover, the application of fecal metabolomics could provide a new strategy to uncover the mechanism of herbal medicines.Key points• Rhubarb could significantly improve gut microbiota disorder in constipation rats.• Rhubarb could markedly modulate the fecal metabolite profile of constipated rats.

High Anal Canal Pressure and Rectal Washouts Contribute to the Decrease of Anal Basal Pressure After Botulinum Toxin Injections in Paediatric Patients With Chronic Constipation. Front Pediatr 2022; 10:819529. [PMID: 35391742 PMCID: PMC8980778 DOI: 10.3389/fped.2022.819529] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/21/2021] [Accepted: 02/14/2022] [Indexed: 11/17/2022] Open
Abstract
INTRODUCTION Chronic constipation can be treated by injecting botulinum toxin into the anal sphincter to decrease anal basal pressure. To assess the effect of botulinum toxin, we investigated the factors that contribute to changes in anal basal pressure after injection. METHODS This was a retrospective study conducted in a tertiary hospital in the Netherlands. We included children with chronic constipation treated with botulinum toxin injections and measured anal basal pressure before and after each injection. Multivariable linear regression analyses were used. RESULTS We investigated 30 cases with idiopathic constipation. Their median age was 20.5 (7.75-53.25) months. Anal basal pressure decreased after injection in 20 cases. The mean decrease of anal basal pressure after injection was 18.17 ± 35.22 mmHg. The anal basal pressure change was linearly correlated with preinjection pressure (R 2 = 0.593, P < 0.001). A significant decrease of pressure was observed in patients with preinjection pressure > 70 mmHg. Preinjection anal basal pressure (β = -0.913, P < 0.001) and rectal washouts (β = -21.015, P = 0.007) contributed significantly to pressure changes. Changes in anal basal pressure were also significantly associated with patients' weights (β = 0.512, 95% CI, 0.011-1.013) and sex (β = 22.971, 95% CI, 9.205-36.736). CONCLUSIONS Botulinum toxin significantly decreases anal basal pressure when preinjection pressure is higher than 70 mmHg. In patients with severely elevated anal basal pressure, we recommend rectal washouts to promote the decrease of anal basal pressure.

Digital Rectal Examination Is a Valuable Bedside Tool for Detecting Dyssynergic Defecation: A Diagnostic Study and a Meta-Analysis. Can J Gastroenterol Hepatol 2021; 2021:5685610. [PMID: 34746041 PMCID: PMC8568520 DOI: 10.1155/2021/5685610] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/13/2021] [Accepted: 10/20/2021] [Indexed: 12/22/2022] Open
Abstract
BACKGROUND Accurate dyssynergic defecation (DD) diagnosis depends on anorectal physiological tests that are not widely available. AIM The purpose of this study is to evaluate the diagnostic yield of digital rectal examination (DRE) compared with anorectal physiological tests in diagnosing DD in patients with constipation. METHODS A total of 218 chronic constipation patients who fulfilled the Rome IV diagnostic criteria for functional constipation (FC) and underwent a standardized DRE and high-resolution anorectal manometry (HRAM) test were enrolled in this study. The diagnostic accuracy of DRE compared with HRAM was evaluated, and the agreement between DRE and HRAM was calculated. Furthermore, a comprehensive literature search on PubMed, Web of Science, Cochrane Library, and Embase database was conducted to further elucidate the pooled diagnostic accuracy of DRE in DD patients. RESULTS A total of 101 patients (46.33%) had a DD pattern using HRAM, while 117 patients (53.67%) were diagnosed without DD. The sensitivity of DRE in diagnosing dyssynergia was 71.3%, and the specificity was 76.1%. There was a moderate agreement between DRE and HRAM for diagnosing DD (κ-coefficient = 0.474, P < 0.001). Meanwhile, six studies (including our study) comprising 964 constipated patients were included in our meta-analysis. The outcomes demonstrated that the AUC was 0.85 (95% CI 0.82-0.88) with 77% summary sensitivity (95% CI 65-86) and 80% summary specificity (95% CI 71-86) to diagnose DD. CONCLUSIONS DRE could be a valuable tool for screening DD. Our study revealed acceptable sensitivity and specificity of DRE in detecting dyssynergia compared with the physiological tests. Meanwhile, our study highlights that DRE remains an important tool in clinical practice.

Abstract
OBJECTIVES Rectocele is common in female patients. To date, there is no literature comparing outcomes of rectocele repairs in combination with other perineal surgeries. We aim to analyze perioperative morbidity and mortality as well as long-term outcome of rectocele repair in combination with other perineal surgeries (RR combination) and compare this with solo rectocele repair (solo RR). DESIGN The type of study was case-control. Data of patients who received solo rectocele repair or rectocele repair in combination with other perineal surgeries between January 2011 and December 2015 were identified and reviewed in a prospectively maintained and IRB-approved database. Ninety-eight patients were included, including 41 patients in the solo RR group and 57 patients in the RR combination group. The demographics, characteristics of patients, short-term complications, long-term complications, and morbidity of the 2 groups were observed. METHODS The demographics, characteristics of patients, short-term complications, long-term complications, and morbidity of the 2 groups were compared, respectively. Covariate adjustment was analyzed by multivariate logistic and Cox regression analysis. RESULTS Ninety-eight patients with a median age of 57 were included, involving 41 patients in the solo RR group and 57 patients in the RR combination group. Other than the operative approach (p < 0.01), demographics and preoperative characteristics of the 2 groups were comparable. All variables, including length of stay, estimated blood loss, self-limiting rectal bleeding, transfusion, urinary retention, rectal stricture, rectal and perineal infection, rectovaginal abscess, reoperation, effective resolution of obstructive defecation symptoms, residual symptoms rate, and recurrence rate, were comparable among the 2 groups except for operative time (p = 0.03). LIMITATIONS This study is a single-center study, which may cause bias. In addition, the sample size is limited. Staging of rectocele and routine imaging studies were not performed. CONCLUSIONS Rectocele repair in combination with other perineal surgeries is feasible, and outcomes are comparable with solo rectocele repair. Transanal versus transvaginal repairs appear to have no influence on outcomes.

Abstract
Background Functional constipation (FC) is a health concern that is prevalent in the pediatric population. It lowers the quality of life and increases the probability of comorbidities. As a complementary modality, herbal medicine has been considered useful in a variety of conditions. Persian medicine (PM) resources mention the Viola flower as an effective herb in treating constipation. The purpose of the current trial was to evaluate the efficacy of Viola flower syrup (VFS) compared with polyethylene glycol (PEG) in children with functional constipation. Methods This randomized, active-controlled, single-center trial was conducted on 140 children aged between 4 and 10 years with confirmed FC according to Rome III criteria. Participants were randomly assigned to receive either VFS or PEG for four weeks. Independent t-test and general linear model (GLM) repeated measures analysis of variance were used to determine the intergroup difference, and paired sample t-test was used to evaluate the intragroup difference. Results After four weeks of intervention, 133 individuals (66 in VFS and 67 in the PEG group) were analyzed. Results of both groups demonstrated significant improvement in all measured criteria at the end of the study compared to baseline (P < 0.001). No significant difference was observed between the two groups at baseline or at the end of the study (P > 0.05), except for fecal retention at baseline (P=0.028). Participants in the PEG group experienced more side effects compared to the VFS group. Conclusion The findings of this investigation indicated that VFS is an effective and relatively safe medication to be used in the treatment of pediatric FC.

Abstract
Abstract
Background
Obstructed defecation is a common pelvic floor medical problem among adult population. Pelvic floor disorders were reported to be associated with sexual dysfunction including erectile dysfunction among male patients. The aim was to determine the relation between pelvic floor neurophysiological abnormalities and erectile dysfunction in male patients with obstructed defecation.
Methods
This cross-sectional study included 65 married male patients with obstructed defecation and a control group consisted of 15 apparently healthy married males. Assessment of obstructed defecation severity was done by using modified obstructed defecation score, time of toileting and Patient Assessment of Constipation-Quality of Life questionnaire. Assessment of erectile functions was done using erectile function domain of International Index of Erectile Function questionnaire and Erectile Dysfunction-Effect on Quality of Life Questionnaire. Anal manometry and dynamic pelvis magnetic resonance imaging were done. Electrophysiological studies included pudendal nerve motor conduction study and needle electromyography of external anal sphincter, puborectalis and bulbocavernosus muscles.
Results
There were 32 patients (49.2%) who had erectile dysfunction. The maximum straining anal pressure was significantly higher among patients with erectile dysfunction. Pudendal nerve terminal motor latency was significantly delayed and the percentage of bilateral pudendal neuropathy was significantly higher among patients with erectile dysfunction. The percentage of electromyography evidence of denervation with chronic reinnervation in the external anal sphincter and bulbocavernosus muscles were significantly higher among patients with erectile dysfunction. Regression analysis detected three co-variables to be associated with significantly increasing the likelihood of development of erectile dysfunction. These were maximum straining anal pressure (odd ratio = 1.122), right pudendal nerve terminal motor latency (odd ratio = 3.755) and left pudendal nerve terminal motor latency (odd ratio = 3.770).
Conclusions
Erectile dysfunction is prevalent among patients with obstructed defecation. It is associated with characteristic pelvic floor electrophysiological abnormalities. Pelvic floor neurophysiological changes vary from minimal to severe neuromuscular abnormalities that usually accompanying erectile dysfunction. Pudendal neuropathy and increased maximum straining anal pressure are essential risk factors for increasing the likelihood of development of erectile dysfunction in patients with obstructed defecation.

Abstract
Biomechatronics (bionics) is an applied science that is interdisciplinary between biology and engineering (mechanical, electrical and electronics engineering). Biomechatronics covers a wide area and is probably best known in development of prosthetic limbs, vision aids, robotics and neuroscience. Although the gastrointestinal tract is difficult to study, it is particularly suited for a bionics approach as demonstrated by recent developments. Ingestible capsules that travel the tract and record physiological variables have been used in the clinic. Other examples include sacral nerve stimulators that seek to restore normal anorectal function. Recently, we developed a simulated stool termed fecobionics. It has the shape of normal stool and records a variety of parameters including pressures, bending (anorectal angle) and shape changes during colonic transit and defecation, i.e. it integrates several current tests. Fecobionics has been used to study defecation patterns in large animals as well as in humans (normal subjects and patient groups including patients with symptoms of obstructed defecation and fecal incontinence). Recently, it was applied in a canine colon model where it revealed patterns consistent with shallow waves originating from slow waves generated by the interstitial cells of Cajal. Furthermore, novel analysis such as the rear-front pressure (preload-afterload) diagram and quantification of defecation indices have been developed that enable mechanistic insight. This paper reviews the fecobionics technology and outlines perspectives for future applications.

Abstract
INTRODUCTION Defecatory disorders including obstructed defecation (OD) are currently diagnosed using specialized investigations including anorectal manometry and the balloon expulsion test. Recently, we developed a simulated stool named Fecobionics that provides a novel type of pressure measurements and analysis. The aim was to study OD phenotypes compared with slow transit constipation (STC) patients and normal subjects (NS). METHODS Fecobionics expulsion parameters were assessed in an interventional study design. The Fecobionics device contained pressure sensors at the front, rear, and inside a bag. All constipation patients had colon transit study, defecography, anorectal manometry, and balloon expulsion test performed. The Fecobionics bag was distended in the rectum until desire-to-defecate in 26 OD compared with 8 STC patients and 10 NS. Rear-front pressures (preload-afterload parameters) and defecation indices (DIs) were compared between groups. RESULTS The Wexner constipation scoring system score was 13.8 ± 0.9 and 14.6 ± 1.5 in the OD and STC patients (P > 0.5). The median desire-to-defecate volume was 80 (quartiles 56-80), 60 (54-80), and 45 (23-60) mL in OD, STC, and NS, respectively (P < 0.01). The median expulsion duration was 37 (quartiles 15-120), 6 (3-11), and 11 (8-11) seconds for the 3 groups (P < 0.03). Fecobionics rear-front pressure diagrams demonstrated clockwise loops with distinct phenotype differences between OD and the other groups. Most DIs differed between OD and the other groups, especially those based on the anal afterload reflecting the nature of OD constipation. Several OD subtypes were identified. DISCUSSION Fecobionics obtained novel pressure phenotypes in OD patients. DIs showed pronounced differences between groups. Larger studies are needed on OD subtyping.

Abstract
INTRODUCTION Defecation is a complex process that is difficult to study and analyze. OBJECTIVES Here, we present new analytical tools to calculate frictional force and tension during expulsion of the Fecobionics simulated stool in human subjects. METHODS The 12-cm-long Fecobionics device contained pressure sensors, motion processor units for measurement of orientation and bending, and impedance rings for measurement of cross-sectional areas. Eight normal subjects defecated Fecobionics. The bending angle of the device, frictional force between the device and the surrounding tissue, and the stretch tensions were calculated. RESULTS The bending angle and pressures changed during expulsion with the maximum pressure recorded at the rear. The averaged circumferential tension, longitudinal tension and friction force in each subject were associated with the front-rear pressure difference (r > 0.7, p < 0.005). The peak circumferential tension, longitudinal tension, and friction force immediately before expulsion of the rear were significantly higher compared to when the front entered the anal canal (F = 164.7, p < 0.005; F = 152.1, p < 0.005; F = 71.4, p < 0.005; respectively.). CONCLUSION This study shows that Fecobionics obtained reliable data under physiological conditions. Mechanical features such as frictional force and stretch tensions were assessable during Fecobionics expulsion.

Abstract
BACKGROUND Outlet obstruction constipation accounts for about 30% of chronic constipation (CC) cases in a referral practice. AIMS To assess the proportion of patients with CC diagnosed with descending perineum syndrome (DPS) by a single gastroenterologist and to compare clinical, radiological, and associated features in DPS compared to patients with constipation. METHODS We conducted a review of records of 300 consecutive patients evaluated for constipation by a single gastroenterologist from 2007 to 2019, including medical, surgical, and obstetrics history, digital rectal examination, anorectal manometry, defecation proctography (available in 15/23 with DPS), treatment, and follow-up. DPS was defined as > 3 cm descent of anorectal junction on imaging or estimated perineal descent on rectal examination. Logistic regression with univariate and multivariate analysis compared factors associated with DPS to non-DPS patients. RESULTS Twenty-three out of 300 (7.7%, all female) patients had DPS; these patients were older, had more births [including more vaginal deliveries (84.2% vs. 31.2% in non-DPS, p < 0.001)], more instrumental or traumatic vaginal deliveries, more hysterectomies, more rectoceles on proctography (86.7% vs. 28.6% non-DPS, p = 0.014), lower squeeze anal sphincter pressures (p < 0.001), and lower rectal sensation (p = 0.075) than non-DPS. On univariate logistic regression, history of vaginal delivery, hysterectomy, and Ehlers-Danlos syndrome increased the odds of developing DPS. Vaginal delivery was confirmed as a risk factor on multivariate analysis. CONCLUSIONS DPS accounts for almost 10% of tertiary referral patients presenting with constipation. DPS is associated with age, female gender, and number of vaginal (especially traumatic) deliveries.

EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE : ECAM 2020; 2020:8798974. [PMID: 33029178 PMCID: PMC7532427 DOI: 10.1155/2020/8798974] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 05/30/2020] [Revised: 08/01/2020] [Accepted: 09/05/2020] [Indexed: 02/06/2023]
Abstract
BACKGROUND Stimulant laxatives are still considered the most common treatment for functional outlet obstruction constipation (FOOC). However, the effectiveness of laxatives is unsatisfactory, and the long-term use of laxatives may cause certain adverse events. With this in mind, it is, however, paramount that novel complementary treatment(s) and/or other forms of alternative medicine are adequately investigated. AIMS The study aims to explore the effects and potential mechanism(s) of transcutaneous electrical acustimulation (TEA) combined with adaptive biofeedback training (ABT) on FOOC. METHODS A total of forty-five patients with FOOC were recruited and were randomly assigned to receive either Macrogol 4000 Powder (MAC, 10 g bid) (group A, n = 15) only, ABT + MAC + Sham-TEA (group B, n = 15), or TEA + ABT + MAC (group C, n = 15) in a six-week study. Individual patients' constipation-symptoms (PAC-SYM) and constipation-quality of life (PAC-QOL) were both assessed and scored. Serum acetylcholine (Ach) and nitric oxide (NO) were measured from drawn blood samples while individual patients' heart rate variability (HRV) was calculated at baseline and after each corresponding therapy. Anorectal manometry and balloon expulsion test were both performed before and after treatment. RESULTS Firstly, participants in group C had significantly lower scores of PAC-SYM, PAC-QOL, and a decreased anal defecating pressure (ADP) as compared to participants in group B (all p < 0.050). These results, however, suggest the TEAs effect. Secondly, the low-frequency band (LF)/(LF + HF) ratio in groups B and C were decreased as compared to group A (p=0.037, p=0.010, respectively) regarding HRV. On the other hand, the high-frequency band (HF)/(LF + HF) ratio in groups B and C showed an opposite outcome. Finally, the serum Ach in groups B and C was significantly higher as compared to group A (p=0.023, p=0.012, respectively). Of significant importance, the serum NO in groups B and C were notably low as compared to group A (p=0.001, p < 0.001, respectively). CONCLUSIONS TEA, combined with ABT, effectively improves constipation symptoms as well as QOL in FOOC patients. It is, however, achieved by decreasing ADP, which mechanisms are mediated via the autonomic and enteric mechanisms.

Abstract
BACKGROUND Rectal evacuation involves multiple mechanisms that are not completely understood. The aim of this study was to quantify the rheologic property, i.e., yield stress, which governs the ease of deformation of a range of faeces of differing consistency and understand its influence on the pathophysiology of defaecation. METHODS Yield stresses of faeces of differing consistencies and Bristol scores were determined by the Vane test. We then explored the effects of this property on ease of defecation using a simple static model of the recto-anal junction based on the laws of flow for yield stress pastes and checked the conclusions by X-ray defaecography experience. RESULTS The yield stress of faeces increased exponentially with their solid content, from 20 to 8000 Pa. The static model of the recto-anal junction showed that evacuation of faeces of normal consistency and yield stress is possible with moderate dilatation of the anal canal, whilst the evacuation of faeces with higher yield stress requires greater dilatation of the anal canal. X-ray defaecography showed that such increases occurred in vivo. CONCLUSIONS The diameter of the recto-anal junction is increased to enable the passage of feces with high yield stress. The finite limits to such dilation likely contribute to fecal impaction. Hence, difficulties in defaecation may result either from unduly high yield stress or pathologies of reflex recto-anal dilatation or a combination of the two.

Abstract
PURPOSE Although various strategies exist for chronic constipation therapy, the pathogenesis of chronic constipation is still not completely understood. The aim of this exploratory experimental study is to elucidate alterations of the autonomous enteric nervous system at the molecular level in patients with obstructed defecation, who represent one of the most predominant groups of constipated patients. METHODS Full-thickness rectal wall samples of patients with obstructed defecation were analyzed and compared with controls. Differential gene expression analyses by RNA-Seq transcriptome profiling were performed and gene expression profiles were assigned to gene ontology pathways by application of different biological libraries. RESULTS Analysis of the transcriptome showed that genes associated with the enteric nervous system functions were significantly downregulated in patients with obstructed defecation. These affected functions included developmental processes and synaptic transmission. CONCLUSIONS Our results therefore indicate that obstructed defecation may represent an enteric neuropathy, comparable to Hirschsprung disease and slow-transit constipation.

Abstract
PURPOSE OF REVIEW To overview the current medical literature on the efficacy of botulism toxin treatment (BTX-A) for lower gastrointestinal disorders (GIT). RECENT FINDINGS BTX-A was found to have a short-term efficacy for the treatment of dyssynergic defecation. Surgical treatment was found to be more effective than BTX-A for the healing of chronic anal fissures, and BTX-A can be considered when surgery is undesirable. Data regarding the effects of BTX-A injection for the treatment of chronic anal pain is limited. Beneficial effects were observed only in a minority of patients. BTX-A treatment was found to be effective for the treatment of obstructive symptoms after surgery for Hirsprung's disease as well as for the treatment of internal anal sphincter achalasia. BTX-A treatment has a short-term efficacy and is safe. Further research is still needed in order to establish the exact place of BTX-A treatment of lower GIT disorders.

Abstract
Introduction and hypothesis: Descending Perineum Syndrome (DPS) is a coloproctologic disease and the best treatment for it is yet to be defined. DPS is frequently associated with pelvic organ prolapse (POP) and it is reasonable to postulate, that treatment of POP will also have an impact on DPS. We aimed to evaluate the subjective satisfaction and improvement of DPS for patients who have undergone a sacral colpoperineopexy associated with retrorectal mesh for concomitant POP. Methods: This retrospective cohort study, conducted between February 2010 and May 2016 included all women who had undergone surgery to treat POP and DPS. Improvement of POP was assessed clinically and subjective satisfaction was assessed with a survey. Results: Among the 37 operated patients, 31 responded to the questionnaire and 77.4% were satisfied with this surgical procedure. 94.6% were objectively cured for POP. There was a 60% improvement rate for constipation, 63.5 and 68% were cured or improved for ODS and the need for digital maneuvers respectively. Conclusion: Sacral colpoperineopexy associated with retrorectal dorsal mesh appears to objectively and subjectively improve POP associated with DPS.

Abstract
BACKGROUND/OBJECTIVE In the late's 90' a new surgical treatment, the stapled trans-anal rectal resection (STARR) was born to treat obstructed defecation syndrome (ODS). In this study we retrospectively analyze a series of 450 cases that underwent STARR in 10 years. METHODS Between January 2001 to December 2011, 450 patients, diagnosed with ODS syndrome caused by rectocele or intussusception, underwent to STARR procedure. The presence of rectocele and/or intussusception was verified by dynamic defecography. The preoperative evaluation was completed with anorectal manometry and colonoscopy. Follow-up visits were scheduled 1 week, 1 month, 3 months, 1 years, 3 years and 5 years after surgery. RESULTS Mean operative time was 30,2 min. In 408 cases (90.7%) hospital discharge occurred 24 hours after surgery. Among postoperative complications urinary retention was observed in 35 patients (7.8%). Five (1.1%) patients presented an early rectal bleeding and 8 (1.8%) patients presented a late bleeding. In 5 (1.1%) patients a stable pelvic hematoma was found. Six (1.3%) patients presented pelvic sepsis due to subperitoneal perforation. An asymptomatic partial dehiscence of stapler row occurred in 19 patients (4.2%).125 patients (27.8%) reported defecation urgency that completely vanished at 3 months follow-up in 83 patients (66,4%) and in further 42 patients (33,6%) at 6-months. The average preoperative ODS score was 14.1; 3.1 at one year; 4.3 at 3 years and 6.4 after five years. CONCLUSIONS In expert hands, with right indications, STARR procedure is safe with good results in terms of improvement of the ODS score.

Abstract
Functional constipation is a common bowel disorder leading to activity restrictions and reduced health-related quality of life. Typically, this condition is initially managed with prescription of laxatives or fiber supplementation, or both. However, these interventions are often ineffective and fail to address the underlying pathophysiology and impairments contributing to this condition. Physical therapists possess the knowledge and skills to diagnose and manage a wide range of musculoskeletal and motor coordination impairments that may contribute to functional constipation. Relevant anatomic, physiologic, and behavioral contributors to functional constipation are discussed with regard to specific constipation diagnoses. A framework for physical therapist examination of impairments that can affect gastrointestinal function, including postural, respiratory, musculoskeletal, neuromuscular, and behavioral impairments, is offered. Within the context of diagnosis-specific patient cases, multifaceted interventions are described as they relate to impairments underlying functional constipation type. The current state of evidence to support these interventions and patient recommendations is summarized. This perspective article aims not only to heighten physical therapists' awareness and management of this condition, but also to stimulate clinical questioning that will open avenues for future research to improve patient care.

Abstract
BACKGROUND Korean cactus Cheonnyuncho (Opuntia humifusa) is rich in pectin, phenols, flavonoids, and minerals such as calcium and phosphorus. Some Koreans drink Cheonnyuncho juice prepared by grinding Cheonnyuncho with water. Cheonnyuncho is well known for its functional properties and antioxidant effects, but its effect on constipation has not been sufficiently studied. METHODS Loperamide (2 mg/kg) was injected subcutaneously to induce constipation in rats. The animals were divided into four groups: a normal group (NOR), constipation control group (CON), and two constipation groups receiving the Cheonnyuncho extract (CE) at two different concentrations in drinking water, 3% (L-CE group) and 6% (H-CE group), for 25 days. RESULTS The fecal pellet numbers of NOR and L-CE were significantly increased from 35.67 ± 2.09 (CON) to 50.60 ± 1.38 and 46.50 ± 2.91 after loperamide treatment, respectively (p < 0.05). The water content of fecal excretions was significantly enhanced in only the L-CE group (33.05 ± 0.49%) compared to control (23.38 ± 1.26%) (p < 0.05) after loperamide treatment. The oral intake of CE (L-CE and H-CE groups) significantly increased levels of the intestinal transit ratio (45.25 ± 1.86% and 41.05 ± 2.47%, respectively) compared to the CON group (32.15 ± 2.05%) (p < 0.05). Treatment with the low concentration of CE significantly increased fecal levels of acetic, propionic, butyric, and valeric acids, as well as the total short-chain fatty acid (SCFA) concentration. Histological analyses revealed that the thickness of the distal colon also increased in the CE-treated groups in a dose-dependent manner. CONCLUSIONS Constipation decreased when CE was fed to the rats. In particular, the fecal pellet number and water content, as well as histological parameters such as distal colon thickness, improved. The CE treatment also increased the fecal SCFA content. These results show that the extract of Cheonnyuncho (O. humifusa) alleviated the symptoms of loperamide-induced constipation.

Abstract
AIM Imaging for pelvic floor defaecatory dysfunction includes defaecation proctography. Integrated total pelvic floor ultrasound (transvaginal, transperineal, endoanal) may be an alternative. This study assesses ultrasound accuracy for the detection of rectocele, intussusception, enterocele and dyssynergy compared with defaecation proctography, and determines if ultrasound can predict symptoms and findings on proctography. Treatment is examined. METHOD Images of 323 women who underwent integrated total pelvic floor ultrasound and defaecation proctography between 2011 and 2014 were blindly reviewed. The size and grade of rectocele, enterocele, intussusception and dyssynergy were noted on both, using proctography as the gold standard. Barium trapping in a rectocele or a functionally significant enterocele was noted on proctography. Demographics and Obstructive Defaecation Symptom scores were collated. RESULTS The positive predictive value of ultrasound was 73% for rectocele, 79% for intussusception and 91% for enterocele. The negative predictive value for dyssynergy was 99%. Agreement was moderate for rectocele and intussusception, good for enterocele and fair for dyssynergy. The majority of rectoceles that required surgery (59/61) and caused barium trapping (85/89) were detected on ultrasound. A rectocele seen on both transvaginal and transperineal scanning was more likely to require surgery than if seen with only one mode (P = 0.0001). If there was intussusception on ultrasound the patient was more likely to have surgery (P = 0.03). An enterocele visualized on ultrasound was likely to be functionally significant on proctography (P = 0.02). There was, however, no association between findings on imaging and symptoms. CONCLUSION Integrated total pelvic floor ultrasound provides a useful screening tool for women with defaecatory dysfunction such that defaecatory imaging can avoided in some.

Abstract
OBJECTIVE Defaecatory MRI allows multicompartmental assessment of defaecatory dysfunction but is often inaccessible. Integrated total pelvic floor ultrasound (transperineal, transvaginal, endoanal) may provide a cheap, portable alternative. The accuracy of total pelvic floor ultrasound for anatomical abnormalities when compared with defaecatory MRI was assessed. METHODS The dynamic images from 68 females who had undergone integrated total pelvic floor ultrasound and defaecatory MRI between 2009 and 2015 were blindly reviewed. The following were recorded: rectocoele, enterocoele, intussusception and cystocoele. RESULTS There were 26 rectocoeles on MRI (49 rectocoeles on ultrasound), 24 rectocoeles with intussusception on MRI (19 rectocoeles on ultrasound), 23 enterocoeles on MRI (24 enterocoeles on ultrasound) and 49 cystocoeles on MRI (35 cystocoeles on ultrasound). Sensitivity and specificity of total pelvic floor ultrasound were 81% and 33% for rectocoele, 60% and 91% for intussusception, 65% and 80% for enterocoele and 65% and 84% for cystocoele when compared with defaecatory MRI. This gave a negative-predictive value and positive-predictive value of 74% and 43% for rectocoele, 80% and 79% for intussusception, 82% and 63% for enterocoele and 48% and 91% for cystocoele. CONCLUSION Integrated total pelvic floor ultrasound may serve as a screening tool for pelvic floor defaecatory dysfunction; when normal, defaecatory MRI can be avoided, as rectocoele, intussusception and enterocoele are unlikely to be present. Advances in knowledge: This is the first study to compare integrated total pelvic floor ultrasound with defaecatory MRI. The results support the use of integrated total pelvic floor ultrasound as a screening tool for defaecatory dysfunction.

Abstract
BACKGROUND Data on fecal evacuation disorder (FED) causing chronic constipation (CC) is scanty in India. METHODS Prospectively maintained data of 249 consecutive patients with CC (Rome III) referred for investigations were retrospectively analyzed. RESULTS Of 249 patients (43.7 ± 16.2 years, 174 males), 135/242 (55.8 %), 57/249 (22.9 %), and 83/136 (61.0 %) had abnormal balloon expulsion test (>200 g), anorectal manometry [>100 mmHg resting pressure (n = 4), >167 mmHg squeeze pressure (n = 46), and both (n = 7)], and defecography (anorectal angle not opening by >15° during defecation, perineal descent ≥4 cm, and/or rectocele), respectively. Though 181/249 (72.6 %) had one test abnormality, 86/249 (34 %) had FED (greater than or equal to two abnormalities), 44/65 (67.6 %) of whom had a defecation index ≤1.4. Rome III criteria for irritable bowel syndrome were equally fulfilled by patients with and without FED [74/83 (89 %) vs. 117/144 (81.2 %); p = ns]. On univariate analysis, straining duration, prolonged straining [≥30 min; 21/39 (53.8 %) vs. 15/65 (23.1 %); p = 0.002], incomplete evacuation [75/77 (97.4 %) vs. 95/114 (83.3 %); p = 0.004], and >3 stools/week [60/75 (80 %) vs. 76/128 (60 %); p = 0.004] were commoner among the FED patients though age, gender, symptom duration, mucus, manual evacuation, and stool forms were comparable. Resting and squeeze pressures and balloon volume at maximum tolerable limit were higher, and the sphincter tended to be shorter in FED. Prolonged straining, incomplete evacuation, and squeeze pressure were significant on multivariate analysis. Manometry and defecography abnormalities were commoner among the female FED patients. CONCLUSION FED is not uncommon, which fulfills the Rome III criteria for IBS, and prolonged straining may be suggestive; abnormal defecography and manometry are commoner in female.

Abstract
Small bowel obstructions (SBOs) are common in patients who have undergone Ileal J-pouch-anal anastomosis (IPAA) surgery. SBO may be caused by stenosis of the diverting ileostomy, volvulus, internal hernia, adhesive bands, anastomotic stricture or intra-abdominal adhesions. Functional outlet obstruction is an important alternative diagnosis to consider in a patient post-IPAA presenting with obstructive symptoms. Recognition of this condition can prevent unnecessary surgery and save the patient from presenting repeatedly with obstructive symptoms.

Abstract
INTRODUCTION AND HYPOTHESIS Defecatory dysfunction is a relatively common and challenging problem among women and one that practicing pelvic reconstructive surgeons and gynecologists deal with frequently. A subset of defecatory dysfunction includes obstructed defecation, which can have multiple causes, one of which is descending perineum syndrome (DPS). METHODS A literature search was performed to identify the pathophysiology, diagnosis, and management of DPS. RESULTS Although DPS has been described in the literature for many decades, it is still uncommonly diagnosed and difficult to manage. A high index of suspicion combined with physical examination consistent with excess perineal descent, patient symptom assessment, and imaging in the form of defecography are required for the diagnosis to be accurately made. Primary management options of DPS include conservative measures consisting of bowel regimens and biofeedback. Although various surgical approaches have been described in limited case series, no compelling evidence can be demonstrated at this point to support surgical intervention. CONCLUSIONS Knowledge of DPS is essential for the practicing pelvic reconstructive surgeon to make a timely diagnosis, avoid harmful treatments, and initiate therapy early on.

Abstract
BACKGROUND Constipation is a clinical symptom in patients suffering from slow transit and/or obstructed defecation. Proper treatment requires the identification of all associated disorders and the quantification of symptoms. Rectocele can cause the symptoms of obstructed defecation syndrome (ODS). The aim of this study was to evaluate the clinical and functional outcomes of a novel technique of transvaginal stapled rectal resection (TVSRR) using a straight staple line, to treat rectocele. METHODS The study included 84 females [median age 51 years (range 29-73 years)], with obstructed defecation, grades II-III rectocele, and multiple abnormalities on defecography. The magnitude and degree of ODS were quantified by the Altomare ODS scoring system. Continence status was evaluated using the Pescatori scoring system. The rectal and vaginal manometric study, the index of patient satisfaction using a visual analog score (VAS), and the validated Patient Assessment of Constipation Quality of Life (PAC-QOL) questionnaire results were recorded. All patients underwent TVSRR. RESULTS There were no intraoperative complications. Early postoperative complications were defecatory urgency in seven patients (8.3 %), dyspareunia in two (2.4 %), and rectovaginal fistula in one (1.2 %). Five patients (6 %) had recurrence of ODS symptoms. There was no significant change in continence pre- and postoperatively. The ODS score and VAS revealed significant improvement within the first postoperative year in 94 % of patients. The PAC-QOL questionnaire mean total scores indicated an improvement in both the patient satisfaction and the QOL during the 12-month follow-up. The self-reported definitive outcome was excellent in 46 patients (54.7 %), good in 29 (34.5 %), fairly good in 20 (23.8 %), and poor in five (6.0 %). CONCLUSIONS Vaginal repair carries no risk of fecal incontinence. Large anterior rectocele is considered the main indication for this technique. Using the linear stapler is a cost-effective, simple, and easy technique.

Abstract
Background Electroacupuncture (EA) is used clinically for the treatment of constipation. Serotonin (5-hydroxytryptamine, 5-HT) plays an important role in colonic motility; however it is unknown whether alterations in colonic 5-HT are associated with EA. In this study, the effect and mechanism of EA at acupuncture points LI11 and ST37 were examined using a cold saline-induced rat model of constipation. Methods A rat constipation model was induced by cold saline gavage in 24 Sprague-Dawley rats. A further six rats were included as a Control group. The constipated rats were divided into four groups (n=6 each): a Constipation group that remained untreated; a Constipation+LI11 group that received EA at LI11; a Constipation+ST37 groups that received EA at ST37; and a Constipation+LI11+ST37 group that received EA at both LI11 and ST37. After EA treatment, faecal water content, defaecation frequency, and gastrointestinal (GI) transit were measured, as well as the expression of tryptophan hydroxylase (TPH) in colonic tissues (by Western blot analysis) and 5-HT in both faeces and colonic tissues (by ELISA). Results All three EA-treated groups demonstrated significant improvements in faecal water content, defaecation frequency and GI transit (p<0.05). In addition, TPH and 5-HT expression were both increased by EA at LI11 and/or ST37 (p<0.05). There were no significant differences between the three EA groups for any outcomes. Conclusions EA at LI11 and/or ST37 had a positive effect on objective markers of constipation in a rat model. In addition, EA increased 5-HT and TPH in the colonic tissues.

Abstract
BACKGROUND Little is known about how obstructive defecation and colonic inertia symptoms contribute to constipation-related quality of life. OBJECTIVE We sought to characterize the differences in quality of life in patients with severe obstructive defecation and colonic inertia symptoms. DESIGN This study was a cross-sectional analysis of a prospective database. SETTING Patients were enrolled at a single tertiary referral center. PATIENTS We included consecutive adults with severe symptoms of obstructive defecation (n = 115) or colonic inertia (n = 90) as measured by the Constipation Severity Instrument. MAIN OUTCOME MEASURES 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. RESULTS 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). LIMITATIONS The use of patient self-report instruments resulted in a proportion of patients with incomplete data. CONCLUSION 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.

Abstract
AIM: To compare the follow-up outcomes of ileosigmoidal anastomosis (ISA) and caecorectal anastomosis (CRA) in patients with slow transit constipation (STC) with or without melanosis coli (MC).
METHODS: We collected the clinical data of 48 STC patients with or without MC from May 2002 to May 2007. Twenty-six patients underwent CRA (14 with MC) and 22 cases received ISA (14 with MC). A 3-year postoperative follow-up was conducted.
RESULTS: CRA improved the quality of life [evaluated by the gastrointestinal quality of life index (GIQLI)] in patients without MC, but was inferior to ISA in stool frequency and Wexner and GIQLI scores for MC patients. In the CRA group, patients with MC suffered worse outcomes than those without MC.
CONCLUSION: CRA is more suitable for STC patients without MC; however, for STC patients with MC, ISA is a better choice.

Abstract
BACKGROUND Defecography is a study to assess anorectal function during evacuation. OBJECTIVE To investigate the value of fluoroscopic defecography in directing diagnostic and therapeutic management in children with defecation disorders. MATERIALS AND METHODS We reviewed all fluoroscopic defecography studies performed (2003-2009) in children with defecation problems and normal anorectal motility studies. Results were classified into three groups: (1) normal pelvic floor function; (2) pelvic floor dyssynergia, including incomplete relaxation of pelvic musculature, inconsistent change in anorectal angle and incomplete voluntary evacuation; (3) structural abnormality, including excessive pelvic floor descent with an intra-rectal intussusception, rectocele or rectal prolapse. RESULTS We included 18 patients (13 boys, median age 9.1 years). Indication for fluoroscopic defecography was chronic constipation in 56%, fecal incontinence in 22% and rectal prolapse in 22%. Defecography showed pelvic floor dyssynergia in 9 children (50%), a structural abnormality in 4 (22%) and normal pelvic floor function in 5 (28%). In 12 children (67%) the outcome of fluoroscopic defecography directly influenced therapeutic management. After defecography 4 children (22%) were referred for anorectal biofeedback treatment, 4 children (22%) for surgery, 2 children (11%) for additional MR defecography, and 1 child to the psychology department, and medication was changed in 1 child. In 6 children (33%) the result did not change the management. In 9 children (75%) the change of management was successful. CONCLUSIONS Fluoroscopic defecography can be a useful tool in understanding the pathophysiology and it may provide information that impacts management of children with refractory defecation disorders.
