Abstract
Surgical treatment has been widely used in patients with refractory slow transit constipation (RSTC). The aim of this network meta-analysis (NMA) was to compare the effects of different colectomies on short-term postoperative complications and quality of life in patients with RSTC. Electronic literature searches were performed in the PubMed, Web of Science, EMBASE, WANFANG DATA, and Cochrane Central Register of controlled trials databases and were searched up to December 2022. Selected to compare the short-term clinical outcomes and quality of life of the treatment of RSTC. A random-effects Bayesian NMA was conducted to assess and rank the effectiveness of different surgical modalities. This study included a total of six non-randomized controlled trials involving 336 subjects. It was found that subtotal colectomy with cecorectal anastomosis (CRA) demonstrated superior effectiveness in several aspects, including reduced hospital stay (MD 0.06; 95% CI [0.02, 1.96]), shorter operative time (MD 4.75; 95% CI [0.28, 14.07]), lower constipation index (MD 0.61; 95% CI [0.04, 1.71]), improved quality of life (MD 4.42; 95% CI [0.48, 4.42]). Additionally, in terms of short-term clinical outcomes, subtotal colectomy with ileosigmoidal anastomosis (SC-ISA) procedure ranked the highest in reducing small bowel obstruction (OR 0.24; 95% CI [0.02, 0.49]), alleviating abdominal pain (OR 0.53; 95% CI [0.05, 1.14]), minimizing abdominal distension (OR 0.33; 95% CI [0.02, 0.65]), and reducing incision infection rates (OR 0.17; 95% CI [0.01, 0.33]). Furthermore, SC-ISA ranked as the best approach in terms of patient satisfaction (OR 0.66; 95% CI [0.02, 1.46]). Based on our research findings, we recommend that CRA be considered as the preferred treatment approach for patients diagnosed with RSTC.

Abstract
PURPOSE Defecation disorders (DD) can sometimes affect the outcomes of pelvic or colorectal surgery. The aim of the present study is to evaluate the role of sacral neuromodulation for the treatment of constipation and other evacuation disorders after surgery. METHODS A retrospective analysis in all the consecutive patients that underwent sacral nerve modulation (SNM) for DD arisen or worsened after pelvic or colorectal surgery was performed from January 2010 to December 2020. DD were defined starting from Rome IV Criteria, and according to manometric results, all patients were further divided into the two subgroups: inadequate defecatory propulsion and dyssynergic defecation. Cleveland Clinic Constipations Score (CCCS) and SF-36 have been evaluated in the time. RESULTS Thirty-seven patients have been included in the study. Twenty-seven out of thirty-seven (73.3%) patients had experienced sufficient benefits to implant the definitive device, and 22 patients (59.4% of tested and 81.5% of permanently implanted) still had the device functioning after a mean follow-up of 6.3 years. The most represented manometric pattern was inadequate propulsive function (59% of patients). CCCS at preoperative assessment for all patients was 17.5 with a reduction to 10.4 at the first year of follow-up (p < 0.001). CONCLUSION SNM appears to be a feasible, safe, and well-tolerated procedure with durable benefit in the long-term treatment of defecatory dysfunction after pelvic or colorectal surgery for benign diseases.

The Persistency Index: a novel screening tool for identifying myofascial pelvic floor dysfunction in patients seeking care for lower urinary tract symptoms. Am J Obstet Gynecol 2023; 229:667.e1-667.e11. [PMID: 37633575 PMCID: PMC11000817 DOI: 10.1016/j.ajog.2023.08.017] [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: 04/24/2023] [Revised: 07/31/2023] [Accepted: 08/16/2023] [Indexed: 08/28/2023]
Abstract
BACKGROUND Patients with myofascial pelvic floor dysfunction often present with lower urinary tract symptoms, such as urinary frequency, urgency, and bladder pressure. Often confused with other lower urinary tract disorders, this constellation of symptoms, recently termed myofascial urinary frequency syndrome, is distinct from other lower urinary tract symptoms and optimally responds to pelvic floor physical therapy. A detailed pelvic floor myofascial examination performed by a skilled provider is currently the only method to identify myofascial urinary frequency syndrome. Despite a high influence on quality of life, low awareness of this condition combined with no objective diagnostic testing leads to the frequent misdiagnosis or underdiagnosis of myofascial urinary frequency syndrome. OBJECTIVE This study aimed to develop a screening measure to identify patients with myofascial urinary frequency syndrome (bothersome lower urinary tract symptoms secondary to myofascial pelvic floor dysfunction) from patient-reported symptoms. STUDY DESIGN A population of patients with isolated myofascial urinary frequency syndrome was identified by provider diagnosis from a tertiary urology practice and verified by standardized pelvic floor myofascial examination and perineal surface pelvic floor electromyography. Least Angle Shrinkage and Selection Operator was used to identify candidate features from the Overactive Bladder Questionnaire, Female Genitourinary Pain Index, and Pelvic Floor Distress Index predictive of myofascial urinary frequency syndrome in a pooled population also containing subjects with overactive bladder (n=42), interstitial cystitis/bladder pain syndrome (n=51), and asymptomatic controls (n=54) (derivation cohort). A simple, summated score of the most discriminatory questions using the original scaling of the Pelvic Floor Distress Index 5 (0-4) and Genitourinary Pain Index 5 (0-5) and modified scaling of Female Genitourinary Pain Index 2b (0-3) had an area under the curve of 0.75. As myofascial urinary frequency syndrome was more prevalent in younger subjects, the inclusion of an age penalty (3 points added if under the age of 50 years) improved the area under the curve to 0.8. This score was defined as the Persistency Index (possible score of 0-15). The Youden Index was used to identify the optimal cut point Persistency Index score for maximizing sensitivity and specificity. RESULTS Using a development cohort of 215 subjects, the severity (Pelvic Floor Distress Index 5) and persistent nature (Female Genitourinary Pain Index 5) of the sensation of incomplete bladder emptying and dyspareunia (Female Genitourinary Pain Index 2b) were the most discriminatory characteristics of the myofascial urinary frequency syndrome group, which were combined with age to create the Persistency Index. The Persistency Index performed well in a validation cohort of 719 patients with various lower urinary tract symptoms, including overactive bladder (n=285), interstitial cystitis/bladder pain syndrome (n=53), myofascial urinary frequency syndrome (n=111), controls (n=209), and unknown diagnoses (n=61), exhibiting an area under the curve of 0.74. A Persistency Index score ≥7 accurately identified patients with myofascial urinary frequency syndrome from an unselected population of individuals with lower urinary tract symptoms with 80% sensitivity and 61% specificity. A combination of the Persistency Index with the previously defined Bladder Pain Composite Index and Urge Incontinence Composite Index separated a population of women seeking care for lower urinary tract symptoms into groups consistent with overactive bladder, interstitial cystitis/bladder pain syndrome, and myofascial urinary frequency syndrome phenotypes with an overall diagnostic accuracy of 82%. CONCLUSION Our study recommends a novel screening method for patients presenting with lower urinary tract symptoms to identify patients with myofascial urinary frequency syndrome. As telemedicine becomes more common, this index provides a way of screening for myofascial urinary frequency syndrome and initiating pelvic floor physical therapy even before a confirmatory pelvic examination.

Abstract
BACKGROUND & AIMS Anorectal manometry (ARM) is a comprehensive diagnostic tool for evaluating patients with constipation, fecal incontinence, or anorectal pain; however, it is not widely utilized for reasons that remain unclear. The aim of this roundtable discussion was to critically examine the current clinical practices of ARM and biofeedback therapy by physicians and surgeons in both academic and community settings. METHODS Leaders in medical and surgical gastroenterology and physical therapy with interest in anorectal disorders were surveyed regarding practice patterns and utilization of these technologies. Subsequently, a roundtable was held to discuss survey results, explore current diagnostic and therapeutic challenges with these technologies, review the literature, and generate consensus-based recommendations. RESULTS ARM identifies key pathophysiological abnormalities such as dyssynergic defecation, anal sphincter weakness, or rectal sensory dysfunction, and is a critical component of biofeedback therapy, an evidence-based treatment for patients with dyssynergic defecation and fecal incontinence. Additionally, ARM has the potential to enhance health-related quality of life and reduce healthcare costs. However, it has significant barriers that include a lack of education and training of healthcare providers regarding the utility and availability of ARM and biofeedback procedures, as well as challenges with condition-specific testing protocols and interpretation. Additional barriers include understanding when to perform, where to refer, and how to use these technologies, and confusion over billing practices. CONCLUSIONS Overcoming these challenges with appropriate education, training, collaborative research, and evidence-based guidelines for ARM testing and biofeedback therapy could significantly enhance patient care of anorectal disorders.

Abstract
Objectives The aim of this study was to evaluate the effects of probiotics on the treatment of constipation in patients with Parkinson's disease (PD) by analyzing data from published randomized clinical trials (RCTs). PD is a neurodegenerative disease characterized by clinical symptoms such as rigidity, bradykinesia, and resting tremor. Constipation is a common complaint reported by PD patients. Probiotics are often used to treat functional constipation. The potential mechanisms behind PD-related constipation include dysfunction of the enteric nervous system due to alpha-synuclein aggregation, dyssynergic contractions of the puborectalis muscle, and alterations of the gut microbiome. Method To conduct this study, we searched Scopus, PubMed, and Google Scholar for published articles on PD, probiotics, and constipation. We selected RCTs from 944 studies, and ultimately included 3 RCTs in our meta-analysis. The frequency of bowel movements per week was the only index that could be summarized among the records. We extracted and analyzed the results as means and standard deviations. Result We calculated a standardized mean difference (SMD) of 0.92 (95% CI, 0.65 to 1.19; I-squared = 57.0%; p < 0.001) to determine the treatment effect in terms of frequency of bowel movements per week in the RCTs. Conclusion Our results show that probiotic intake has beneficial effects on constipation in PD patients. Further research, including multicenter studies, is needed to assess the long-term efficacy and safety of probiotic supplements in neurodegenerative diseases.

Abstract
Background/Aims Elobixibat, an ileal bile acid transporter (apical sodium-dependent bile acid transporter) inhibitor, was recently launched in Japan for the treatment of chronic idiopathic constipation. We conducted an interim analysis of post-marketing surveillance to evaluate the safety and efficacy of elobixibat in elderly patients with chronic constipation and compared the efficacy according to administration time. Methods Safety and efficacy outcomes were evaluated through patient interviews for 4 weeks. Results Adverse drug reactions (ADRs) were observed in 5.24% of the 1049 patients analyzed; diarrhea (2.19%) and abdominal pain (1.81%) were the most common. A serious ADR of death was reported in one patient (0.10%). The incidence of ADRs in the ≥ 65-year old or ≥ 75-year-old subpopulation was similar to that in the total patient population. Mean bowel movements per week significantly increased from 2.9 ± 2.5 at baseline to 5.0 ± 3.1 (P < 0.001) at Week 2 and 5.3 ± 2.6 (P < 0.001) at Week 4. The mean Bristol Stool Form Scale score significantly increased from 2.3 ± 1.4 at baseline to 3.8 ± 1.3 (P < 0.001) at Week 2 and 3.9 ± 1.1 at Week 4 (P < 0.001). Bowel movements significantly increased in the elderly population and subpopulations receiving elobixibat before breakfast, lunch, or dinner. The median time to bowel movement was 5 hours. Conclusion The results suggested that elobixibat was well-tolerated and efficacious in elderly patients with chronic constipation and can be administered before any meals.

Abstract
The first two objectives were to establish which stimulation parameters of kilohertz frequency alternating current (KHFAC) neuromodulation influence the effectiveness of pudendal nerve block and its safety. The third aim was to determine whether KHFAC neuromodulation of the pudendal nerve can relax the pelvic musculature, including the anal sphincter. Simulation experiments were conducted to establish which parameters can be adjusted to improve the effectiveness and safety of the nerve block. The outcome measures were block threshold (measure of effectiveness) and block threshold charge per phase (measure of safety). In vivo, the pudendal nerves in 11 male and 2 female anesthetized Sprague Dawley rats were stimulated in the range of 10 Hz to 40 kHz, and the effect on anal pressure was measured. The simulations showed that block threshold and block threshold charge per phase depend on waveform, interphase delay, electrode-to-axon distance, interpolar distance, and electrode array orientation. In vivo, the average anal pressure during unilateral KHFAC stimulation was significantly lower than the average peak anal pressure during low-frequency stimulation (p < 0.001). Stimulation with 20 kHz and 40 kHz (square wave, 10 V amplitude, 50% duty cycle, no interphase delay) induced the largest anal pressure decrease during both unilateral and bilateral stimulation. However, no statistically significant differences were detected between the different frequencies. This study showed that waveform, interphase delay and the alignment of the electrode along the nerve affect the effectiveness and safety of KHFAC stimulation. Additionally, we showed that KHFAC neuromodulation of the pudendal nerves with an electrode array effectively reduces anal pressure in rats.

Abstract
INTRODUCTION We conducted this meta-analysis, to compare cecorectal (CRA) and ileorectal anastomosis (IRA), regarding perioperative safety and efficacy, in patients submitted to colectomy for refractory slow transit constipation (STC). METHODS This study followed the Cochrane Handbook for Systematic Reviews of Interventions and the PRISMA guidelines. To identify all eligible records, a systematic literature search in the electronic scholar databases (Medline, Scopus, Web of Science) was performed. RESULTS Overall, 5 trials and 291 patients were included in this meta-analysis. Pooled comparisons confirmed the comparability of the two techniques regarding perioperative complications (p = 0.55). CRA was associated with a shorter operation (p = 0.0004) and hospitalization duration (p = 0.001). Although there was no difference in terms of gastrointestinal symptoms, functional outcomes, and patient satisfaction, CRA resulted in lower long-term Wexner scores (p < 0.0001). CONCLUSION Due to several study limitations, further large-scale RCTs are required to verify the findings of the present meta-analysis.

Dig Dis Sci 2021; 66:3105-3112. [PMID: 33001346 DOI: 10.1007/s10620-020-06626-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/24/2020] [Accepted: 09/16/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND AND AIM Manual abdominal massage has been shown to effectively treat slow-transit constipation, but it is labor-intensive. To offer an alternative treatment option for constipation, the Bamk-001 automatic abdominal massage device was developed. The aim of this study was to assess the effect of the Bamk-001 device on symptom profiles and colon transit time (CTT) in patients with chronic constipation. METHODS Thirty-seven patients with chronic functional constipation diagnosed using the Rome IV criteria were enrolled prospectively from December 2018 to February 2019. All patients received device-assisted automatic abdominal massage for 15 min twice daily, once in the morning before breakfast and once at night, for 14 days. CTT was measured before and at the end of the study period. Slow-transit constipation and very-slow-transit constipation were defined as CTT ≥ 48 h and ≥ 72 h, respectively. Patients' symptom profiles regarding overall defecation satisfaction and device-related adverse events were analyzed. RESULTS Among the 37 patients, the mean age was 40.1 ± 11.8, and 5.4% (n = 2) were men. The Bamk-001 device significantly improved CTT from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.001) in patients with chronic constipation. In subgroup analysis, CTT improved significantly from 54.0 (33.6-75.6) to 28.8 (18.0-52.8) h (p = 0.003) and from 88.2 (74.4-124.8) to 45.6 (27.3-74.1) h (p = 0.005) in the slow-transit and very-slow-transit constipation groups, respectively (p = 0.001). Moreover, all patient symptoms were alleviated after treatment. No serious adverse events were reported. CONCLUSION The Bamk-001 automatic abdominal massage device showed significant care efficacy, including the improvement in CTT and symptom profiles in patients with slow-transit constipation. The use of an automatic abdominal massage device as an adjunct in the management of constipation is a potentially beneficial intervention for patients with slow-transit constipation.

Abstract
Background Colectomy remains a treatment option for a minority of patients with slow-transit constipation (STC) refractory to conservative treatment. However careful patient selection is essential to maximize benefits and minimize risk of adverse outcome. This study determined the proportion of patients with chronic constipation that would meet criteria for colectomy based on recent European graded practice recommendations derived by expert consensus. Methods Retrospective application of graded practice recommendations was undertaken on a prospectively maintained data set of consecutive adult patients with chronic constipation who underwent whole-gut transit studies using radio-opaque markers. Primary analysis applied contraindications achieving high level of expert consensus (normal whole-gut transit as an absolute contraindication and faecal incontinence as a relative contraindication for colectomy). Secondary analysis applied contraindications with less certain consensus. Results Primary analysis of 1568 patients undergoing a whole-gut transit study between January 2004 and March 2016 found 208 (13.3 per cent) met published criteria to be selected for colectomy, with 974 excluded for normal whole-gut transit and 386 for faecal incontinence. Secondary analysis demonstrated high prevalence of other relative contraindications to colectomy: 165 concomitant upper gastrointestinal symptoms, 216 abdominal pain (including 126 irritable bowel syndrome), and 446 evacuation disorder. The majority of patients (416 of 594) had two or more relative contraindications. If these patients were excluded, only 26 (1.7 per cent) chronically constipated patients retrospectively met selection criteria for colectomy. Conclusions The retrospective application of selection criteria is a limitation. However, the data highlight the high prevalence of factors associated with poor postoperative outcome and provide further caution to surgeons undertaking colectomy for STC.

Abstract
Patients with chronic constipation who do not respond to initial treatments often need further evaluation for dyssynergic defecation (DD) and slow transit constipation (STC). The aims of this study are to characterize the prevalence of DD and STC in patients referred to a motility center with chronic constipation and correlate diagnoses of DD and STC to patient demographics, medical history, and symptoms. High-resolution ARM (HR-ARM), balloon expulsion testing (BET) and whole gut transit scintigraphy (WGTS) of consecutive patients with chronic constipation were reviewed. Patients completed questionnaires describing their medical history and symptoms at the time of testing. A total of 230 patients completed HR-ARM, BET, and WGTS. Fifty (22%) patients had DD, and 127 (55%) patients had STC. Thirty patients (13%) had both DD and STC. There were no symptoms that were suggestive of STC vs. DD; however, patients with STC and DD reported more severe constipation than patients with normal transit and anorectal function. Patients with chronic constipation often need evaluation for both DD and STC to better understand their pathophysiology of symptoms and help direct treatment.

Abstract
Slow transit constipation (STC) is a rare condition almost exclusively encountered in middle-aged women. Pathophysiology and aetiology are poorly understood but a multi-factorial pathogenesis seems likely. With regard to differential diagnoses mechanical, drug induced, degenerative, metabolic, endocrinologic, neurologic, and psychiatric causes of constipation must be excluded by an interdisciplinary approach. Gastrointestinal physiologic investigations including colonic transit studies are mandatory. Furthermore, pangastrointestinal delay, pelvic floor dysfunction, and irritable bowel syndrome should be excluded. Initial treatment is strictly conservative. In cases of progression or persistence of symptoms surgical therapy should be discussed. Subtotal colectomy with ileorectal anastomosis is regarded as the standard operation for STC. Using strict selection criteria, overall success rates are reported in excess of 80%.

Abstract
Chronic constipation is one of the five most common symptoms seen by gastroenterologist. In the absence of alarm symptoms, a confident symptom-based diagnosis can often be made using the Rome criteria. Three different subtypes have been identified to date: normal transit constipation, defaecatory disorders and slow transit constipation. Differentiation between these subtypes can be made through functional testing using tests such as anorectal manometry with balloon expulsion and a radio-opaque marker test. In general, patients are initially advised to increase their fluid and fibre intake. When these general lifestyle recommendations do not improve patients' symptoms, a step-wise and add-on treatment approach should be applied. This review summarises the diagnostic criteria to differentiate functional constipation from other causes of chronic constipation. In addition, current drug treatment options, including discussion of new therapeutic targets are discussed. Further, practical treatment approaches (choice and dosing), include discussion of combination/augmentation, treatment failure (adherence/expectations), and relapse prevention are mentioned. Finally, treatment and management of pain and bloating aspects are included.

Abstract
Primary care physicians frequently evaluate patients with constipation. The history is crucial in uncovering warning symptoms and signs that warrant colonoscopy. Particular elements in the history and rectal examination also can provide clues regarding the underlying etiology. Regardless of etiology, lifestyle modifications, fiber, and laxatives are first-line therapies. Patients who fail first-line therapies can be offered second-line treatments and/or referred for testing of defecatory function. In those with severely refractory symptoms, referrals to a gastroenterologist and a surgeon should be considered.

Abstract
INTRODUCTION Slow transit constipation is a major cause of chronic constipation. During pregnancy, changes in hormone levels and the physical effects of an enlarged uterus could cause new onset slow transit constipation or aggravate a pre-existing constipation. The management of slow transit constipation-induced ileus during pregnancy is a medical dilemma. PATIENT CONCERNS A 28-year-old pregnant woman presented to the emergency department with a 7-day history of worsening bloating and abdominal colic. The patient was in her third trimester (27 weeks). She had a 5-year history of constipation which had worsened with her pregnancy, and neither flatus nor stool could be passed. DIAGNOSIS Based on the constipation history and computed tomography, a slow transit constipation-induced ileus was confirmed. INTERVENTIONS As medications for the management of constipation and endoscopic efforts to remove the blockage were ineffective and the patient's symptoms worsened, Cesarean section and colectomy with ileorectal anastomosis were performed. OUTCOMES After the procedure, the patient recovered and defecated well. At the 6-month follow-up, the patient reported that she defecated two to three times per day without difficulty. CONCLUSION Pregnancy can worsen pre-existing constipation and cause ileus. In cases where drug treatment is unsuccessful, colectomy, and ileorectal anastomosis may be necessary.

Abstract
BACKGROUND Slow transit constipation is characterised by prolonged colonic transit and reliance on laxatives. The pathophysiology is poorly understood and in its most severe form, total colectomy with ileorectal anastomosis is the final treatment option. We present a follow-up study of the long-term function in patients who had surgery for laxative-resistant slow transit constipation. METHODS A postal survey was sent to assess bowel frequency, abdominal pain, St Mark's continence score, satisfaction with procedure, likelihood to choose the procedure again, and long-term rates of small bowel obstruction and ileostomy. Longitudinal data from a subgroup studied 23 years previously are reported. RESULTS Forty-two patients (male = 2) were available for follow-up out of an initial cohort of 102. Mean time since surgery was 15.9 years (range 1.7-29.7) years. Fifty percent had < 4 bowel motions per day, most commonly Bristol stool 6, mean St Mark's score 7.45. Twenty-one percent had severe incontinence. Satisfaction and likelihood to choose surgery were high (median 10/10). There was a high rate of small bowel obstruction, suggesting pan-intestinal dysmotility in some cases. Conversion to ileostomy occurred in 8 patients. In the longitudinal follow-up in 15 subjects, continence deteriorated (p < 0.01), stool consistency softened (p < 0.01), and stool frequency fell (p < 0.01). CONCLUSIONS Satisfactory stool frequency was achieved in the long term, and although 21% had incontinence scores > 12, patient satisfaction was high. This is the longest reported follow-up of colectomy for slow transit constipation, with longitudinal outcomes reported. There was considerable attrition of patients, so larger, longitudinal studies are required to better ascertain the functional outcomes of these patients.

Abstract
Constipation is a common symptom that may be primary (idiopathic or functional) or associated with a number of disorders or medications. Although most constipation is self-managed by patients, 22% seek health care, mostly to primary care physicians (>50%) and gastroenterologists (14%), resulting in large expenditures for diagnostic testing and treatments. There is strong evidence that stimulant and osmotic laxatives, intestinal secretagogues, and peripherally restricted μ-opiate antagonists are effective and safe; the lattermost drugs are a major advance for managing opioid-induced constipation. Constipation that is refractory to available laxatives should be evaluated for defecatory disorders and slow-transit constipation using studies of anorectal function and colonic transit. Defecatory disorders are often responsive to biofeedback therapies, whereas slow-transit constipation may require surgical intervention in selected patients. Both efficacy and cost should guide the choice of treatment for functional constipation and opiate-induced constipation. Currently, no studies have compared inexpensive laxatives with newer drugs that work by other mechanisms.

Abstract
AIM The aim of this study is to evaluate the short- and long-term efficacy of sacral nerve stimulation (SNS) for treating slow-transit constipation (STC). METHOD This is a retrospective cohort analysis of the efficacy of SNS in treating patients affected by STC, who previously failed to respond to conservative therapies. Only patients free of concomitant diseases were enrolled in our study. A temporary stimulation lead was initially implanted; patients with a > 50% symptom reduction were eventually deemed eligible for a permanent implant. RESULTS This study enrolled 25 patients who underwent a SNS test stimulation; 21 patients (13 women; median age 32 years) eventually got a permanent implant. The median preoperative Cleveland Clinic Constipation Score (CCCS) was 21 (16-25). Preoperative colorectal transit time recorded a median of 10 markers (7-19) retained in the colorectal tract. At 6-month postoperative follow-up, the total number of markers retained in the colorectal tract decreased to 3 (0-4). The CCCS score improved during the first postoperative year (P < 0.001), but progressively worsened over the longer term. The SF-36 questionnaire showed an improvement in all 8 scales measuring physical and psycho-emotional states; all parameters recorded into the bowel diary also improved. Overall, at 60-month follow up, the overall neuromodulator removal rate was 48%. CONCLUSIONS The SNS is a minimally invasive surgical procedure that we tested for treating STC. The short-term outcome was promisingly after 6 months; however, there was a declining trend beyond this interval. Thus, the long-term efficacy of SNS needs to be further assessed.

Initial Effects of Electroacupuncture for Chronic Severe Functional Constipation and the Potential Underlying Factors: Secondary Analysis of a Randomized Controlled Trial. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2019; 2019:7457219.

Abstract
Background Electroacupuncture (EA) has been found to be effective for treating chronic severe functional constipation (CSFC). However, the initial effects of treatment usually affect the acceptability and compliance of patients with chronic disease in particular. Which class of CSFC patients will have a better initial response to EA remains uncertain and requires investigation. Methods This was a secondary analysis of an original multicenter randomized controlled trial in which patients with CSFC were randomly assigned to receive 28 sessions of EA or sham electroacupuncture (SA) over 8 weeks with 12 weeks of follow-up. The primary outcome, namely, response with complete spontaneous bowel movements (CSBMs), required participants to have ≥ 3 CSBMs and an increase of ≥ 1 CSBM from the baseline over the first week of treatment. Logistic regression analysis with bootstrapping techniques was performed to determine independent factors related to the response. Results A total of 1051 eligible patients were included in this study of whom 161 patients were classified as responders at week 1. The CSBM response rate was higher in the EA group (17.5%) than in the SA group (13.2%). And the proportion of these 1-week early responders remained to have higher clinical response at the end of 8-week treatment and 12 weeks after treatment. Age and higher baseline CSBMs were related to CSBM response within the first week: with every 1-year increase in age, the likelihood of clinical response was reduced by 1.7% (odds ratio [OR] 0.983, 95% confidence interval [CI] 0.972 to 0.993; P=0.001). The odds of a CSBM response in patients with 1< CSBMs ≤ 2 at baseline were 4.64 times higher than that in patients with CSBMs ≤ 1 (OR 4.64, 95%CI 4.01 to 5.27). Conclusions EA produced its initial effects within the first week of treatment. And the effects could last until week 8 and week 20. A younger age and higher number of CSBMs at baseline may increase likelihood of a response.

Abstract
Slow transit constipation (STC) is a common disease characterized by markedly delayed colonic transit time as a result of colonic motility dysfunction. It is well established that STC is mostly caused by disorders of relevant nerves, especially the enteric nervous system (ENS). Colonic electrical stimulation (CES) has been regarded as a valuable alternative for the treatment of STC. However, little report focuses on the underlying nervous mechanism to normalize the delayed colonic emptying and relieve symptoms. In the present study, the therapeutic effect and the influence on ENS triggered by CES were investigated in STC beagles. The STC beagle model was established by oral administration of diphenoxylate/atropine and alosetron. Histopathology, electron microscopy, immunohistochemistry, Western blot analysis and immunofluorescence were used to evaluate the influence of pulse train CES on myenteric plexus neurons. After 5 weeks of treatment, CES could enhance the colonic electromyogram (EMG) signal to promote colonic motility, thereby improving the colonic content emptying of STC beagles. HE staining and transmission electron microscopy confirmed that CES could regenerate ganglia and synaptic vesicles in the myenteric plexus. Immunohistochemical staining showed that synaptophysin (SYP), protein gene product 9.5 (PGP9.5), cathepsin D (CAD) and S-100B in the colonic intramuscular layer were up-regulated by CES. Western blot analysis and immunofluorescence further proved that CES induced the protein expression of SYP and PGP9.5. Taken together, pulse train CES could induce the regeneration of myenteric plexus neurons, thereby promoting the colonic motility in STC beagles.

Abstract
PURPOSE To study the safety and efficacy of laparoscopic subtotal colectomy (LASC) with cecorectal anastomosis for slow-transit constipation (STC). METHODS This study was a retrospective review of all patients undergoing LASC with cecorectal anastomosis for STC between March 2010 and May 2017. The main variables included the operative time, blood loss, length of postoperative hospital stay, complications, and long-term outcomes. RESULTS In this analysis, 56 patients were included. There were 17 males and 39 females aged between 34 and 80 years old. The mean operative time was 208 ± 21 min, and the mean perioperative blood loss was 116 ± 48 mL. The mean postoperative hospital stay was 7.7 ± 3.5 days, and the incidence of perioperative complications was 19.6%, with no mortality. One patient required reoperation because of intra-abdominal bleeding. During the follow-up period, 26.8% of patients suffered from chronic pain and bloating, with no recurrence of STC. The causes of these symptoms included small bowel obstruction (7.1%), slow transit (10.7%), anastomotic stenosis (5.4%) and gastroptosis (3.6%). Postoperatively, after 12 months, the frequency of defecation was 2-4 times per day. Patients with follow-up of at least 60 months, the mean frequency of defecation was 0.9 ± 0.5 times per day. The percentage of satisfaction was 82.1%. CONCLUSION LASC with cecorectal anastomosis is a safe and effective surgical approach for STC, with the majority of patients being satisfied with the outcome of surgery.

Abstract
Gastrointestinal (GI) ailments cover a wide variety of diseases involving the esophagus, stomach, small intestine, large intestine, and rectum. They bring about many inconveniences in daily life in chronic diseases and can even be life threatening in acute cases. Rapid and safe detection approaches are essential for early diagnosis and timely management. Contrast agents for GI imaging can enhance contrast to distinguish abnormal lesions from normal structures. Computed tomography and magnetic resonance imaging are two important diagnostic tools for the evaluation of GI conditions. This review mainly involves several common GI diseases, including inflammatory diseases, intestinal tumors, diarrhea, constipation, and gastroesophageal reflux diseases. Selected contrast agents, such as barium sulfate, iodine-based agents, gadolinium-based agents, and others, are summarized. Going forward, continued endeavors are being made to develop more emerging contrast agents for other imaging modalities.

Abstract
Anorectal disorders are common and present with overlapping symptoms. They include several disorders with both structural and functional dysfunction(s). Because symptoms alone are poor predictors of the underlying pathophysiology, a diagnosis should only be made after evaluating symptoms and physiologic and structural abnormalities. A detailed history, a thorough physical and digital rectal examination and a systematic evaluation with high resolution and/or high definition three-dimensional (3D) anorectal manometry, 3D anal ultrasonography, magnetic resonance defecography and neurophysiology tests are essential to correctly identify these conditions. These physiological and imaging tests play a key role in facilitating a precise diagnosis and in providing a better understanding of the pathophysiology and functional anatomy. In turn, this leads to better and more comprehensive management using medical, behavioral and surgical approaches. For example, patients presenting with difficult defecation may demonstrate dyssynergic defecation and will benefit from biofeedback therapy before considering surgical treatment of coexisting anomalies such as rectoceles or intussusception. Similarly, patients with significant rectal prolapse and pelvic floor dysfunction or patients with complex enteroceles and pelvic organ prolapse may benefit from combined behavioral and surgical approaches, including an open, laparoscopic, transabdominal or transanal, and/or robotic-assisted surgery. Here, we provide an update on the pathophysiology, diagnosis, and management of selected common anorectal disorders.

Abstract
BACKGROUND Percutaneous endoscopic colostomy (PEC) is a technique derived from percutaneous endoscopic gastrostomy. When conservative treatment of chronic obstipation fails, colon irrigation via PEC seems less invasive than surgical interventions. However, previous studies have noted high complication rates of PEC, mostly related to infections. Our aim was to report our experiences with PEC in patients with chronic refractory constipation. METHODS Retrospective analysis of all patients who underwent PEC for refractory constipation in our secondary referral hospital between 2009 and 2016. KEY RESULTS Twelve patients received a PEC for chronic, refractory constipation. Short-term efficacy for relief of constipation symptoms was good in 8 patients and moderate in 4 patients. Two patients had the PEC removed because of spontaneous improvement of constipation. Three patients, who initially noticed a positive effect, preferred an ileostomy over PEC after 1-5 years. One PEC was removed because of an abscess. Long-term efficacy is 50%: 6 patients still use their PEC after 3.3 years of follow-up. No mortality occurred. CONCLUSIONS AND INTERFERENCES PEC offers a technically easily feasible and safe treatment option for patients with chronic constipation not responding to conventional therapy. Long-term efficacy of PEC in our patients is 50%.

Abstract
Objectives After subtotal colectomy, 40% of patients report chronic gastrointestinal symptoms and poor quality of life. Its etiology is unknown. We determined whether small intestinal bacterial overgrowth (SIBO) or small intestinal fungal overgrowth (SIFO) cause gastrointestinal symptoms after colectomy. Methods Consecutive patients with unexplained abdominal pain, gas, bloating and diarrhea (>1 year), and without colectomy (controls), and with colectomy were evaluated with symptom questionnaires, glucose breath test (GBT) and/or duodenal aspiration/culture. Baseline symptoms, prevalence of SIBO/SIFO, and response to treatment were compared between groups. Results Fifty patients with colectomy and 50 controls were evaluated. A significantly higher (p = 0.005) proportion of patients with colectomy, 31/50 (62%) had SIBO compared to controls 16/50 (32%). Patients with colectomy had significantly higher (p = 0.017) prevalence of mixed SIBO/SIFO 12/50 (24%) compared to controls 4/50 (8%). SIFO prevalence was higher in colectomy but not significant (p = 0.08). There was higher prevalence of aerobic organisms together with decreased anaerobic and mixed organisms in the colectomy group compared to controls (p = 0.008). Patients with colectomy reported significantly greater severity of diarrhea (p = 0.029), vomiting (p < 0.001), and abdominal pain (p = 0.05) compared to controls, at baseline. After antibiotics, 74% of patients with SIBO/SIFO in the colectomy and 69% in the control group improved (p = 0.69). Conclusion Patients with colectomy demonstrate significantly higher prevalence of SIBO/SIFO and greater severity of gastrointestinal symptoms. Colectomy is a risk factor for SIBO/SIFO.

Abstract
INTRODUCTION Significant advances have been made in the knowledge and understanding of the epidemiology, pathophysiology, diagnosis, and treatment of chronic constipation, since the publication of the 2011 guidelines on chronic constipation diagnosis and treatment in Mexico from the Asociación Mexicana de Gastroenterología. AIMS To present a consensus review of the current state of knowledge about chronic constipation, providing updated information and integrating the new scientific evidence. METHODS Three general coordinators reviewed the literature published within the time frame of January 2011 and January 2017. From that information, 62 initial statements were formulated and then sent to 12 national experts for their revision. The statements were voted upon, using the Delphi system in 3 voting rounds (2 electronic and one face-to-face). The statements were classified through the GRADE system and those that reached agreement >75% were included in the consensus. RESULTS AND CONCLUSIONS The present consensus is made up of 42 final statements that provide updated knowledge, supplementing the information that had not been included in the previous guidelines. The strength of recommendation and quality (level) of evidence were established for each statement. The current definitions of chronic constipation, functional constipation, and opioid-induced constipation are given, and diagnostic strategies based on the available diagnostic methods are described. The consensus treatment recommendations were established from evidence on the roles of diet and exercise, fiber, laxatives, new drugs (such as prucalopride, lubiprostone, linaclotide, plecanatide), biofeedback therapy, and surgery.

Abstract
Constipation is a digestive disorder that often occurs in the elderly; its main cause is bowel motility disorder. Treatments for patients with chronic constipation include pharmacotherapy, diet changes, and surgery if other therapies do not offer satisfactory results. We describe 4 patients, 2 men (70 and 65 years old) and 2 women (75 and 66 years old), who were diagnosed with chronic constipation (slow transit constipation) and treated with conventional therapy, but did not improve. For that reason, side-to-side ileosigmoidostomy shunting surgery was performed. After the surgery, the average time until normal defecation was 16 days, and the defecation frequency was 3 to 4 times a day with no need for a laxative. No patient had a recurrence of constipation. Based on these results, side-to-side ileosigmoidostomy shunting surgery is expected to restore digestive function and can be considered as an alternative therapy for elderly patients with chronic constipation.

Abstract
Chronic constipation is a prevalent condition that severely impacts the quality of life of those affected. Several types of primary chronic constipation, which show substantial overlap, have been described, including normal-transit constipation, rectal evacuation disorders and slow-transit constipation. Diagnosis of primary chronic constipation involves a multistep process initiated by the exclusion of 'alarm' features (for example, unintentional weight loss or rectal bleeding) that might indicate organic diseases (such as polyps or tumours) and a therapeutic trial with first-line treatments such as dietary changes, lifestyle modifications and over-the-counter laxatives. If symptoms do not improve, investigations to diagnose rectal evacuation disorders and slow-transit constipation are performed, such as digital rectal examination, anorectal structure and function testing (including the balloon expulsion test, anorectal manometry or defecography) or colonic transit tests (such as the radiopaque marker test, wireless motility capsule test, scintigraphy or colonic manometry). The mainstays of treatment are diet and lifestyle interventions, pharmacological therapy and, rarely, surgery. This Primer provides an introduction to the epidemiology, pathophysiological mechanisms, diagnosis, management and quality of life associated with the commonly encountered clinical problem of chronic constipation in adults unrelated to opioid abuse.

Abstract
AIM To evaluate the results of Rehbein procedure with extraperitoneal colorectal anastomosis combined with complex conservative treatment in children with secondary megacolon due to chronic constipation. MATERIAL AND METHODS We carried out surgical interventions in 78 children aged 7-12 years with chronic colostasis resistant to conservative treatment. All patients underwent clinical, laboratory and instrumental examination. All patients were divided into 3 groups depending on type of surgery: group I - colon resection followed by intraperitoneal colorectal anastomosis (28 patients), group II - open Rehbein procedure (29 patients), group III - laparoscopic Rehbein procedure (21 patients). RESULTS Absence of dyspeptic disorders and enterocolitis in remote postoperative period in patients receiving comprehensive treatment enhanced with new additions is the cause of improved outcomes. Type of surgery should be individualized in view of anatomical colon changes and secondary pathological conditions. Some pathological symptoms observed at preoperative period may be recurrent in long-term postoperative period due to wrong selection of surgery. The risk of recurrent chronic constipation is high after colon resection followed by intraperitoneal colorectal anastomosis. CONCLUSION Rehbein procedure may be preferred for management of secondary megarectum and megasigma. Laparoscopic technique reduces surgical trauma and requires less postoperative analgesia.

Abstract
AIM To assess the outcomes of colectomy in adults with chronic constipation (CC). METHOD Standardised methods and reporting of benefits and harms were used for all CapaCiTY reviews that closely adhered to PRISMA 2016 guidance. Main conclusions were presented as summary evidence statements (SES) with a summative Oxford Centre for Evidence-Based Medicine (2009) level. RESULTS Forty articles were identified, providing data on outcomes in 2045 patients. Evidence was derived almost exclusively from observational studies, the majority of which concerned colectomy and ileorectal anastomosis (CIRA) rather than other procedural variations. Average length of stay (LOS) ranged between 7-15 days. Although inconsistent, laparoscopic surgery may be associated with longer mean operating times (210 vs 167 min) and modest decreases in LOS (10-8 days). Complications occurred in approximately 24% of patients. Six (0.4%) procedure-related deaths were observed. Recurrent episodes of small bowel obstruction occurred in about 15% (95%CI: 10-21%) of patients in the long-term, with significant burden of re-hospitalisation and frequent recourse to surgery. Most patients reported a satisfactory or good outcome after colectomy but negative long-term functional outcomes persist in a minority of patients. The influence of resection extent, anastomotic configuration and method of access on complication rates remains uncertain. Available evidence weakly supports selection of patients with an isolated slow-transit phenotype. CONCLUSION Colectomy for CC may benefit some patients but at the cost of substantial short- and long-term morbidity. Current evidence is insufficient to guide patient or procedural selection.

Abstract
BACKGROUND Functional constipation is a common clinical presentation in primary care. Functional defaecation disorders are defined as the paradoxical contraction or inadequate relaxation of the pelvic floor muscles during attempted defaecation (dyssynergic defaecation) and/or inadequate propulsive forces during attempted defaecation. Prompt diagnosis and management of dyssynergic defaecation is hindered by uncertainty regarding nomenclature, diagnostic criteria, pathophysiology and efficacy of management options such as biofeedback therapy. AIM To review the evidence pertaining to the pathophysiology of functional defaecation disorders and the efficacy of biofeedback therapy in the management of patients with dyssynergic defaecation and functional constipation. METHODS Relevant articles addressing functional defaecation disorders and the efficacy of biofeedback therapy in the management of dyssynergic defaecation and functional constipation were identified from a search of Pubmed, MEDLINE Ovid and the Cochrane Library. RESULTS The prevalence of dyssynergic defaecation in patients investigated for chronic constipation is as many as 40%. Randomised controlled trials have demonstrated major symptom improvement in 70%-80% of patients undergoing biofeedback therapy for chronic constipation resistant to standard medical therapy and have determined it to be superior to polyethylene glycol laxatives, diazepam or sham therapy. Long-term studies have shown 55%-82% of patients maintain symptom improvement. CONCLUSIONS Dyssynergic defaecation is a common clinical condition in patients with chronic constipation not responding to conservative management. Biofeedback therapy appears to be a safe, successful treatment with sustained results for patients with dyssynergic defaecation. Further studies are required to standardise the diagnosis of dyssynergic defaecation in addition to employing systematic protocols for biofeedback therapy.

Abstract
Constipation is one of the most frequently reported gastrointestinal (GI) disorders that negatively impacts quality of life and is associated with a significant economic burden to the patients and society. Traditional treatments including lifestyle modification and laxatives are often ineffective in the more severe forms of constipation and over the long term. New medications targeting at intestinal chloride channels and colonic serotonin receptors have been demonstrated effective in recent years. Emerging agents focusing on improving intestinal secretion and/or colonic motility have been shown effective in animal models and even in clinical trials. Recognization of the role of cystic fibrosis transmembrane regulator (CFTR) and calcium-activated chloride channels (CaCCs) in intestine fluid secretion and motility modulation makes CFTR and CaCCs promising molecule targets for anti-constipation therapy. Although there are multiple choices for constipation treatment, there is still a recognized need for new medications in anti-constipation therapy. The present review covers the discovery of luminally acting agents for constipation treatment described in both patents (2011–present) and scientific literatures.

Characterization the response of Korl:ICR mice to loperamide induced constipation. Lab Anim Res 2016; 32:231-240.

Abstract
Animal models of constipation induced with drugs and diet have been widely employed to investigate therapeutic effects and the action mechanism of drugs against this disease. ICR mice were selected to produce this disease model through oral administration of loperamide (Lop), even though SD rats are commonly utilized in studies of constipation. To compare the responses of ICR mice obtained from three different sources to constipation inducers, alterations in stool number, histopathological structure, mucin secretion and opioid-receptor downstream signaling pathway were measured in Korl:ICR (Korea FDA source), A:ICR (USA source) and B:ICR (Japan source) injected with low and high concentrations of Lop (LoLop and HiLop). The number, weight and moisture content of stools decreased significantly in the Lop treated group of all ICR relative to the Vehicle treated group. Additionally, decreased mucosa layer thickness, muscle thickness, and mucin secretion were observed in the transverse colon of Lop treated ICR mice, while a similar number of goblet cells and crypt of lieberkuhn were detected in the same group. Furthermore, a similar change in the level of Gα expression and PKC phosphorylation was detected in the Lop treated group relative to the vehicle treated group, while some differences in the change pattern were observed in the B:ICR group. Therefore, these results of the present study provide strong additional evidence that Korl:ICR, A:ICR and B:ICR derived from different sources have a similar overall response to constipation induced by Lop injection, although there were a few differences in the magnitude of their responses.

Abstract
Constipation is a very common complaint, with slow-transit constipation (STC) accounting for a significant proportion of cases. Old age, female gender, psychiatric illness, and history of sexual abuse are all associated with STC. The exact cause of STC remains elusive; however, multiple immune and cellular changes have been demonstrated. Diagnosis requires evidence of slowed colonic transit which may be achieved via numerous modalities. While a variety of medical therapies exist, these are often met with limited success and a minority of patients ultimately require operative intervention. When evaluating a patient with STC, it is important to determine the presence of concomitant obstructed defecation or other forms of enteric dysmotility, as this may affect treatment decisions. Although a variety of surgical procedures have been reported, subtotal colectomy with ileorectal anastomosis is the most commonly performed and well-studied procedure, with the best track record of success.

Abstract
BACKGROUND Evacuatory dysfunction (ED) is a common cause of constipation and may be sub-classified on the basis of specialist tests. Such tests may guide treatment e.g., biofeedback therapy for 'functional' defecatory disorders (FDD). However, there is no gold standard, and prior studies have not prospectively and systematically compared all tests that are used to diagnose forms of ED. METHODS One hundred consecutive patients fulfilling Rome III criteria for functional constipation underwent four tests: expulsion of a rectal balloon distended to 50 mL (BE50 ) or until patients experienced the desire to defecate (BEDDV ), evacuation proctography (EP) and anorectal manometry. Yields and agreements between tests for the diagnosis of ED and FDD were assessed. KEY RESULTS Positive diagnostic yields for ED were: BEDDV 18%, BE50 31%, EP 38% and anorectal manometry (ARM) 68%. Agreement was substantial between the two balloon tests (k = 0.66), only fair between proctography and BE50 (k = 0.27), poor between manometry and proctography (k = 0.01), and there was no agreement between the balloon tests and manometry (k = -0.07 for both BE50 and BEDDV ). For the diagnosis of FDD, there was only fair agreement between ARM and EP (k = 0.23), ARM ± BE50 and EP (k = 0.18), ARM and EP ± BE50 (k = 0.30) and ARM ± BE50 and EP ± BE50 (k = 0.23). CONCLUSIONS & INFERENCES There is considerable disagreement between the results of various tests used to diagnose ED and FDD. This highlights the need for a reappraisal of both diagnostic criteria, and what represents the 'gold standard' investigation.

Abstract
Dyssynergic defecation is common and affects up to one half of patients with chronic constipation. This acquired behavioral problem is due to the inability to coordinate the abdominal and pelvic floor muscles to evacuate stools. A detailed history, prospective stool diaries, and a careful digital rectal examination will not only identify the nature of bowel dysfunction, but also raise the index of suspicion for this evacuation disorder. Anorectal physiology tests and balloon expulsion test are essential for a diagnosis. Newer techniques such as high-resolution manometry and magnetic resonance defecography can provide mechanistic insights. Recently, randomized controlled trials have shown that biofeedback therapy is more effective than laxatives and other modalities, both in the short term and long term, without side effects. Also, symptom improvements correlated with changes in underlying pathophysiology. Biofeedback therapy has been recommended as the first-line of treatment for dyssynergic defecation. Here, we provide an overview of the burden of illness and pathophysiology of dyssynergic defecation, and how to diagnose and treat this condition with biofeedback therapy.

Abstract
BACKGROUND Neostigmine, an acetyl cholinesterase inhibitor, stimulates colonic motor activity and may induce vagally mediated cardiovascular effects. Our aim was to evaluate effects of i.v. neostigmine on colonic compliance and its safety in patients with chronic constipation. METHODS We retrospectively reviewed medical records of a selected group of 144 outpatients with chronic constipation who were refractory to treatment. These patients had undergone intracolonic motility and compliance measurements with an infinitely compliant balloon linked to a barostat. Data abstracted included barostat balloon mean volumes with increases in pressure (4 mmHg steps from 0 to 44 mmHg) before and after i.v. neostigmine. Vital signs and oxygen saturation before and after neostigmine were recorded. KEY RESULTS Of the 144 patients, 133 were female, mean age was 41.0 ± 15.4 years (SD), and duration of constipation was 12.9 ± 13.8 years. Among patients who had undergone colonic transit measurement by scintigraphy, the overall colonic transit at 24 h (geometric center, GC24 [n = 115]) was 1.5 ± 0.7 (normal >1.3), and at 48 h (GC48 [n = 75]) it was 2.3 ± 0.9 (normal >1.9). Neostigmine decreased colonic compliance at lower distension pressures (e.g., 12 and 20 mmHg [both p < 0.001]), but not at 40 mmHg. There were expected minor changes in vital signs in response to neostigmine in 144 patients; however, one patient developed unresponsiveness, significant bradycardia, hypotension, and muscular rigidity that responded to 400 mcg i.v. atropine. CONCLUSIONS & INFERENCES Neostigmine significantly decreases colonic compliance in patients with refractory chronic constipation. Symptomatic bradycardia in response to neostigmine should be promptly reversed with atropine.

Abstract
Background. Surgery for GI dysmotility is limited to those with severe refractory disease. Though effective, use of serotonergic promotility drugs has been restricted in Canada due to adverse events. We aimed to investigate utilization of promotility serotonergic drugs in patients under consideration for surgical management. Methods. A retrospective cohort study was conducted using prospectively collected data. The study population included consecutive patients referred to a motility clinic for consideration of bowel resection at a Canadian tertiary hospital (1996-2011). Univariable tests and multivariable logistic regression analyses were used to assess predictors of serotonergic drug use. Results. Of 128 patients, the majority (n = 98, 76.6%) had constipation-dominant symptoms. Only 25% (n = 32) had tried serotonergic promotility drugs. There was no association between use of these drugs and severity of constipation nor was there an association between serotonergic drug use and presence of diffuse dysmotility (all p > 0.05). The majority of patients (n = 97, 75.8%) underwent some type of surgical resection, which was associated with considerable morbidity (n = 13, 13.4%). Conclusions. Surgical management of GI dysmotility results in serious morbidity. Serotonergic promotility drugs may allow patients to avoid surgery but disease severity does not predict use of these drugs.

Abstract
Background and Objectives: To evaluate the effects of subtotal colectomy combined with the modified Duhamel procedure on mixed constipation. Methods: A total of 16 female patients with mixed constipation were enrolled and underwent subtotal colectomy combined with the modified Duhamel procedure under laparoscopy from April 2010 to April 2012. Before surgery, physical examinations such as the gastrointestinal transit test, barium enema, and defecography were performed for all the patients. After surgical treatment, 2-year follow-up was performed using questionnaires to assess the effect of treatment. Results: All 16 cases were treated successfully, with a mean operation time of 230 minutes (range, 180–290 minutes). No intraoperative or postoperative complications were found, and no deaths occurred. Constipation and relevant symptoms were relieved, and all patients were satisfied with their quality of life. The gastrointestinal quality-of-life score was significantly increased 6 months postoperatively (mean, 102) compared with preoperatively (mean, 75). Conclusion: Subtotal colectomy combined with the modified Duhamel procedure under laparoscopy is effective and safe for the treatment of mixed constipation.

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
INTRODUCTION Chronic constipation is a global problem affecting all ages and associated with considerable morbidity and significant financial burden for society. Though formerly defined on the basis of a single symptom, infrequent defecation; constipation is now viewed as a syndrome encompassing several complaints such as difficulty with defecation, a sense of incomplete evacuation, hard stools, abdominal discomfort and bloating. AREAS COVERED The expanded concept of constipation has inevitably led to a significant change in outcomes in clinical trials, as well as in patient expectations from new therapeutic interventions. The past decades have also witnessed a proliferation in therapeutic targets for new agents. Foremost among these have been novel prokinetics, a new category, prosecretory agents and innovative approaches such as inhibitors of bile salt transport. In contrast, relatively few effective therapies exist for the management of those anorectal and pelvic floor problems that result in difficult defecation. EXPERT OPINION Though constipation is a common and often troublesome disorder, many of those affected can resolve their symptoms with relatively simple measures. For those with more resistant symptoms a number of novel, effective and safe options now exist. Those with defecatory difficulty (anismus, pelvic floor dysfunction) continue to represent a significant management challenge.

Abstract
BACKGROUND Current guidelines include subtotal colectomy as treatment for refractory slow transit constipation. AIM To use the US Nationwide Inpatient Sample (NIS) (1998-2011) and longitudinal data from the State Inpatient Database (2005-2011), comparable to NIS, to examine colectomy rates, in-hospital morbidity and emergency department (ED) visits or readmissions among patients treated for constipation. METHODS Colectomies for any reason were identified based on the primary procedural code (ICD-9-CM 45.8x). Index hospitalisations were defined by the primary diagnosis of constipation (ICD-9-CM 564.x) associated with the primary procedural code for colectomy (ICD-9-CM45.8x) after exclusion of other diseases associated with colectomy. Demographic variables, comorbidities, complications and adverse events during the hospitalisation were captured, and ED visits and admissions were recorded for periods before and after colectomy. RESULTS Nationally, colectomies for constipation rose from 104 procedures in 1998 (1.2% of annual colectomies) to 311 in 2011 (2.4% of annual colectomies). While there were no perioperative deaths, perioperative complications occurred in 42.7% of patients during the index hospitalisation. Longitudinal data were analysed for 181 patients, with similar perioperative complications and a readmission rate of 28.9% within the first 30 days after the index hospitalisation. Resource utilisation was tracked for a median time of 630 (0-2386) before and 463 (0-2204) days after colectomy with unchanged ED visits (median: 2 vs. 2, P = 0.21), but increased hospitalisations (median: 1 vs. 2, P = 0.003). CONCLUSIONS Colectomy rates for constipation are rising, are associated with significant morbidity and do not decrease resource utilisation, raising questions about the true benefit of surgery for slow transit constipation.

Abstract
To characterize the changes in global gene expression in the distal colon of constipated SD rats in response to the laxative effects of aqueous extracts of Liriope platyphylla (AEtLP), including isoflavone, saponin, oligosaccharide, succinic acid and hydroxyproline, the total RNA extracted from the distal colon of AEtLP-treated constipation rats was hybridized to oligonucleotide microarrays. The AEtLP treated rats showed an increase in the number of stools, mucosa thickness, flat luminal surface thickness, mucin secretion, and crypt number. Overall, compared to the controls, 581 genes were up-regulated and 216 genes were down-regulated by the constipation induced by loperamide in the constipated rats. After the AEtLP treatment, 67 genes were up-regulated and 421 genes were down-regulated. Among the transcripts up-regulated by constipation, 89 were significantly down-regulated and 22 were recovered to the normal levels by the AEtLP treatment. The major genes in the down-regulated categories included Slc9a5, klk10, Fgf15, and Alpi, whereas the major genes in the recovered categories were Cyp2b2, Ace, G6pc, and Setbp1. On the other hand, after the AEtLP treatment, ten of these genes down-regulated by constipation were up-regulated significantly and five were recovered to the normal levels. The major genes in the up-regulated categories included Serpina3n, Lcn2 and Slc5a8, whereas the major genes in the recovered categories were Tmem45a, Rerg and Rgc32. These results indicate that several gene functional groups and individual genes as constipation biomarkers respond to an AEtLP treatment in constipated model rats.

Indian J Gastroenterol 2014; 33:530-6.

Abstract
INTRODUCTION Constipation may be primary or secondary. Pathophysiologic subtypes of primary constipation are dyssynergic defecation (DD), slow (STC), and normal transit constipation (NTC). Clinical subtypes are functional constipation (FC) and constipation predominant IBS (C-IBS). AIMS The objectives of this paper are to study the clinical profile, categorize and compare various subtypes of primary constipation, and to assess the success of biofeedback therapy (BFT) in a non-randomized, uncontrolled open-label study among patients with DD. MATERIAL AND METHODS Consecutive constipation patients (April 2011 to December 2012) were evaluated. Patients <18 years and secondary constipation were excluded. FC and C-IBS were classified by Rome III module. All patients, after excluding secondary constipation, underwent anorectal manometry (ARM) with balloon expulsion test and colon transit study (CTS). Patients with DD were given BFT. RESULTS Out of 128 patients, 23 %, 58 %, and 19 % had secondary constipation, FC, and C-IBS, respectively. Ninety-nine patients had primary constipation. Among those with primary constipation mean age was 53.5 (21-86) years, (77 % males). Forty-six, 15, and 40 had NTC, STC, and DD, respectively. Out of those with DD, 34 had paradoxical anal contraction and 6 had impaired rectal propulsion. FC and C-IBS were clinically and pathophysiologically similar except for abdominal pain. Patients with DD were more likely to have history of finger evacuation, straining, incomplete evacuation, sensation of anorectal obstruction than no DD. Sixty-nine percent of the patients with STC had ≤3 stools/week compared to 37 % with NTC (p-value 0.018). Thirty out of 40 (75 %) patients with DD underwent BFT but 20 completed ≥4 sessions. Seventy percent with ≥4 sessions had improved complete spontaneous bowel movements (CSBM). CONCLUSION NTC was the most common subtype of primary constipation. Symptoms of finger evacuation, sensation of anorectal obstruction, incomplete evacuation, and straining were more prevalent in DD. ARM and CTS could easily identify patients with DD and STC.

Abstract
Chronic constipation is a frequently encountered disorder in clinical practice. Most constipated patients benefit from standard medical approaches. However, current therapies may fail in a proportion of patients. These patients deserve better evaluation and thorough investigations before their labeling as refractory to treatment. Indeed, several cases of apparent refractoriness are actually due to misconceptions about constipation, poor basal evaluation (inability to recognize secondary causes of constipation, use of constipating drugs) or inadequate therapeutic regimens. After a careful re-evaluation that takes into account the above factors, a certain percentage of patients can be defined as being actually resistant to first-line medical treatments. These subjects should firstly undergo specific diagnostic examination to ascertain the subtype of constipation. The subsequent therapeutic approach should be then tailored according to their underlying dysfunction. Slow transit patients could benefit from a more robust medical treatment, based on stimulant laxatives (or their combination with osmotic laxatives, particularly over the short-term), enterokinetics (such as prucalopride) or secretagogues (such as lubiprostone or linaclotide). Patients complaining of obstructed defecation are less likely to show a response to medical treatment and might benefit from biofeedback, when available. When all medical treatments prove to be unsatisfactory, other approaches may be attempted in selected patients (sacral neuromodulation, local injection of botulinum toxin, anterograde continence enemas), although with largely unpredictable outcomes. A further although irreversible step is surgery (subtotal colectomy with ileorectal anastomosis or stapled transanal rectal resection), which may confer some benefit to a few patients with refractoriness to medical treatments.
