Transcutaneous Electrical Acustimulation Improves Constipation Symptoms and Accelerates Colonic Transit in Patients With Slow Transit Constipation Through Autonomic Mechanism. Neuromodulation 2024; 27:382-391. [PMID: 38127047 DOI: 10.1016/j.neurom.2023.11.005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/13/2023] [Revised: 10/05/2023] [Accepted: 11/13/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVES Nearly half of patients with slow transit constipation (STC) are not completely satisfied with their traditional remedies. We aimed to evaluate the therapeutic value and possible involved mechanism of transcutaneous electrical acustimulation (TEA) at ST36 in patients with STC. MATERIALS AND METHODS Seventy patients with STC were randomly divided into TEA (n = 35) and sham-TEA (n = 35) to undergo a two-week treatment with TEA at ST36 or sham point. After the two-week treatment, 18 patients from each group randomly underwent a few physiological tests, including the electrocardiogram (ECG), anorectal manometry, colon transit test, and blood drawing. After a two-week washout period, TEA was performed in both groups for two weeks. RESULTS Spontaneous bowel movements per week were increased, and scores of constipation symptoms were decreased, after a two-week blind TEA but not sham-TEA, which were sustained after a two-week washout period. Improvement in quality of life and psychologic states also was observed with blind TEA treatment. Mechanistically, the two-week blind TEA accelerated colon transit assessed by barium strip excretion rate (the effect was sustained after a two-week washout period), enhanced vagal nerve activity evaluated by the spectral analysis of heart rate variability derived from the ECG, and decreased circulating vasoactive intestinal peptide. CONCLUSIONS Noninvasive TEA relieves constipation and improves quality of life and psychologic states in patients with STC, and the effects are sustained for ≥two weeks. The therapeutic effects of TEA may be attributed to the acceleration of colon transit and decrease of vasoactive intestinal peptide mediated through the vagal mechanism.

Abstract
To investigate the clinical efficacy of laparoscopic total colectomy with ileorectal anastomosis (TC-IRA) and laparoscopic subtotal colectomy with antiperistaltic cecorectal anastomosis (SC-ACRA) on adults with slow transit constipation (STC). One hundred and three patients with STC were assigned to the TC-IRA group (n = 53) and the SC-ACRA group (n = 50). The clinical data were analyzed. The surgery was successful in all patients (100%). Significantly (P = 0.03) more patients took anti-laxatives during hospitalization in the TC-IRA than the SC-ACRA group (39.62% vs. 20.00%). Abdominal pain and distension was present in 33.96% and 32.00% patients in the TC-IRA and SC-ACRA group, respectively, which decreased insignificantly (P > 0.05) to 18.87% and 18.00% 24 months after surgery, respectively. The postoperative Wexner and gastrointestinal quality of life (GIQLI) scores were not significantly different (P > 0.05) at all times after surgery in both groups. The defecation frequency decreased in both groups, and the average defecation frequency was significantly (P < 0.05) higher in the TC-IRA than the SC-ACRA group (3.91 ± 1.23 vs. 3.14 ± 1.15 times/day) at 3 months. Three months after surgery, significantly (P < 0.05) fewer patients were satisfied with defecation frequency in the TC-IRA than the SC-ACRA group (29 vs. 37 patients), whereas the number of patients who were willing to choose the same procedure again was not significantly (P > 0.05) different between the two groups. The WIS score of patients was significantly (P = 0.035) higher in the TC-IRA than the SC-ACRA group (6 vs. 5) 3 months later. TC-IRA and SC-ACRA are both safe and effective for adult slow transit constipation, and can significantly improve the quality of life of patients. Even though SC-ACRA has better early defecation frequency, postoperative antidiarrheal application and satisfaction, the long-term follow-up effects are similar.

Abstract
Tricyclic antidepressants (TCAs) have been used to treat depression and were recently approved for treating irritable bowel syndrome (IBS) patients with severe or refractory IBS symptoms. However, the molecular mechanism of TCA action in the gastrointestinal (GI) tract remains poorly understood. Transient receptor potential channel canonical type 4 (TRPC4), which is a Ca2+‐permeable nonselective cation channel, is a critical regulator of GI excitability. Herein, we investigated whether TCA modulates TRPC4 channel activity and which mechanism in colonic myocytes consequently causes constipation. To prove the clinical benefit in patients with diarrhoea caused by TCA treatment, we performed mechanical tension recording of repetitive motor pattern (RMP) in segment, electric field stimulation (EFS)‐induced and spontaneous contractions in isolated muscle strips. From these recordings, we observed that all TCA compounds significantly inhibited contractions of colonic motility in human. To determine the contribution of TRPC4 to colonic motility, we measured the electrical activity of heterologous or endogenous TRPC4 by TCAs using the patch clamp technique in HEK293 cells and murine colonic myocytes. In TRPC4‐overexpressed HEK cells, we observed TCA‐evoked direct inhibition of TRPC4. Compared with TRPC4‐knockout mice, we identified that muscarinic cationic current (mIcat) was suppressed through TRPC4 inhibition by TCA in isolated murine colonic myocytes. Collectively, we suggest that TCA action is responsible for the inhibition of TRPC4 channels in colonic myocytes, ultimately causing constipation. These findings provide clinical insights into abnormal intestinal motility and medical interventions aimed at IBS therapy.

Abstract
Background Functional gastrointestinal disorders (FGIDs) involve chronic or persistent gastrointestinal symptoms. Laboratory tests show no organic lesions, and the symptoms are due to dysfunction. The most typical FGID is irritable bowel syndrome (IBS). In IBS patients, defecation disorders are common and have adverse effects on daily life. The proper evaluation and analysis of colonic transit are important for the management of defecation disorders in IBS patients. In addition, dietary intake and lifestyle affect colonic transit. An accurate assessment of such factors can guide management, leading to improvements in colonic transit and the resolution of defecation disorders. Main topic The Rome IV diagnostic criteria for IBS are based on subjective symptoms, which must be communicated and explained by the patient, limiting their application. Colonic transit time and ultrasonography are objective tools that can be used to diagnose IBS. In particular, previous studies used colonic transit to accurately distinguish between constipation and normal stool passage and to assess delayed gastrointestinal motility. Diet and lifestyle modifications can improve colonic transit and ameliorate bowel dysfunction. Conclusion Colonic transit can be improved by modifying lifestyle factors. Defecation disorders in IBS patients may be resolved by focusing on such factors. In the future, methods of visualizing defecation disorders due to impaired gastrointestinal motility and objective indicators of the associated abdominal symptoms need to be investigated.

Abstract
Faecal microbiota transplantation (FMT) is the transfer of screened and minimally processed faecal material from a 'healthy' donor to 'diseased' recipient. It has an established role, and is recommended as a therapeutic strategy, in the management of recurrent Clostridioides difficile infection (CDI). Recognition that gut dysbiosis is associated with, and may contribute to, numerous disease states has led to interest in exploiting FMT to 'correct' this microbial imbalance. Conditions for which it is proposed to be beneficial include inflammatory bowel disease, irritable bowel syndrome, liver disease and hepatic encephalopathy, neuropsychiatric conditions such as depression and anxiety, systemic inflammatory states like sepsis, and even coronavirus disease 2019. To understand what role, if any, FMT may play in the management of these conditions, it is important to consider the potential risks and benefits of the therapy. Regardless, there are several barriers to its more widespread adoption, which include incompletely understood mechanism of action (especially outside of CDI), inability to standardise treatment, disagreement on its active ingredients and how it should be regulated, and lack of long-term outcome and safety data. Whilst the transfer of faecal material from one individual to another to treat ailments or improve health has a history dating back thousands of years, there are fewer than 10 randomised controlled trials supporting its use. Moving forward, it will be imperative to gather as much data from FMT donors and recipients over as long a timeframe as possible, and for trials to be conducted with rigorous methodology, including appropriate control groups, in order to best understand the utility of FMT for indications beyond CDI. This review discusses the history of FMT, its appreciable mechanisms of action with reference to CDI, indications for FMT with an emerging evidence base above and beyond CDI, and future perspectives on the field.

Abstract
The gastrointestinal (GI) tract is innervated by the enteric nervous system (ENS), an extensive neuronal network that traverses along its walls. Due to local reflex circuits, the ENS is capable of functioning with and without input from the central nervous system. The functions of the ENS range from the propulsion of food to nutrient handling, blood flow regulation, and immunological defense. Records of it first being studied emerged in the early 19th century when the submucosal and myenteric plexuses were discovered. This was followed by extensive research and further delineation of its development, anatomy, and function during the next two centuries. The morbidity and mortality associated with the underdevelopment, infection, or inflammation of the ENS highlight its importance and the need for us to completely understand its normal function. This review will provide a general overview of the ENS to date and connect specific GI diseases including short bowel syndrome with neuronal pathophysiology and current therapies. Exciting opportunities in which the ENS could be used as a therapeutic target for common GI diseases will also be highlighted, as the further unlocking of such mechanisms could open the door to more therapy-related advances and ultimately change our treatment approach.

Abstract
BACKGROUND Although total or subtotal colectomy for slow-transit constipation (STC) has been proven to be a definite treatment, the associated defecation function and quality of life (QOL) are rarely studied.
AIM To evaluate the effectiveness of surgery for STC regarding defecation function and QOL.
METHODS From March 2013 to September 2017, 30 patients undergoing surgery for STC in our department were analyzed. Preoperative, intra-operative, and postoperative 3-mo, 6-mo, 1-year, and 2-year follow-up details were recorded. Defecation function was assessed by bowel movements, abdominal pain, bloating, straining, laxative, enema use, diarrhea, and the Wexner constipation and incontinence scales. QOL was evaluated using the gastrointestinal QOL index and the 36-item short form survey.
RESULTS The majority of patients (93.1%, 27/29) stated that they benefited from the operation at the 2-year follow-up. At each time point of the follow-up, the number of bowel movements per week significantly increased compared with that of the preoperative conditions (P < 0.05). Similarly, compared with the preoperative values, a marked decline was observed in bloating, straining, laxative, and enema use at each time point of the follow-up (P < 0.05). Postoperative diarrhea could be controlled effectively and notably improved at the 2-year follow-up. The Wexner incontinence scores at 6-mo, 1-year, and 2-year were notably lower than those at the 3-mo follow-up (P < 0.05). Compared with those of the preoperative findings, the Wexner constipation scores significantly decreased following surgery (P < 0.05). Thus, it was reasonable to find that the gastrointestinal QOL index scores clearly increase (P < 0.05) and that the 36-item short form survey results displayed considerable improvements in six spheres (role physical, role emotional, physical pain, vitality, mental health, and general health) following surgery.
CONCLUSION Total or subtotal colectomy for STC is not only effective in alleviating constipation-related symptoms but also in enhancing patients’ QOL.

Cystic fibrosis transmembrane conductance regulator modulates enteric cholinergic activities and is abnormally expressed in the enteric ganglia of patients with slow transit constipation. J Gastroenterol 2019; 54:994-1006.

Abstract
BACKGROUND Cystic fibrosis transmembrane conductance regulator (CFTR) was recently found in the enteric nervous system, where its role is unclear. We aimed to identify which enteric neuronal structures express CFTR, whether CFTR modulates enteric neurotransmission and if altered CFTR expression is associated with slow transit constipation (STC). METHODS Immunofluorescence double labeling was performed to localize CFTR with various neuronal and glial cell markers in the human colon. The immunoreactivity (IR) of CFTR and choline acetyltransferase (ChAT) on myenteric plexus of control and STC colon was quantitatively analyzed. In control colonic muscle strips, electrical field stimulation (EFS) evoked contractile responses and the release of acetylcholine (ACh) was measured in the presence of the CFTR channel inhibitor, CFTR(inh)-172. RESULTS CFTR-IR was densely localized to myenteric ganglia, where it was co-localized with neuronal markers HuC/D and β-tubulin, and glial marker S-100 but little with glial fibrillary acidic protein. Vesicular ACh transport was almost exclusively co-localized with CFTR, but neurons expressing nitric oxide synthase were CFTR negative. Significant reductions of CFTR-IR (P < 0.01) and ChAT-IR (P < 0.05) were observed on myenteric ganglia of STC compared to control. Pre-treatment of colonic muscle strips with CFTR(inh)-172 (10 µM) significantly inhibited EFS-evoked contractile responses (P < 0.01) and ACh release (P < 0.05). CONCLUSIONS Co-localization of CFTR-IR with cholinergic markers, inhibition of EFS-induced colonic muscle contractility and ACh release by CFTR(inh)-172 suggest that CFTR modulates enteric cholinergic neurotransmission. The downregulation of CFTR and ChAT in myenteric ganglia of STC correlated with the impaired contractile responses to EFS.

Abstract
BACKGROUND There has been some controversy regarding the efficacy of sacral nerve stimulation (SNS) for the treatment of chronic constipation, due to less positive outcomes and concerns about cost-effectiveness in the long term. The aim of the present study was to evaluate the long-term outcomes of SNS in patients with chronic constipation. METHODS A retrospective study was conducted on patients who had SNS for chronic constipation in 2008-2017 at our institution. Clinical factors, profile of constipation, physiology studies, and patient satisfaction with SNS therapy were investigated during a follow-up period up to 10 years after the implantation. RESULTS Twenty-nine patients [86% female, median age 49 years (range 17-86)] were tested for SNS, and 24 received implants after a positive test phase [median 47 days (range 21-56 days)]. There were 27 bilateral and 2 unilateral implants, in S3 or S4 depending on best response. Mean follow-up was 59 months. Efficacy was considered as a score > 5 (on a scale of 1-10) in general symptom improvement. Nine (37.9%) implanted patients had a satisfaction score > 5. In 6 cases (25%), patient satisfaction was higher than 9. Due to the small sample size, there were no statistically significant variables considered as predictors of response. CONCLUSIONS Our results agree with current studies which describe around a 30% response of SNS for refractory constipation. However, there is a small group of patients highly satisfied with SNS therapy. More studies are needed to better understand this profile and optimize outcomes.

Abstract
MaZiRenWan (MZRW, also known as Hemp Seed Pill) is a Chinese Herbal Medicine which has been demonstrated to safely and effectively alleviate functional constipation (FC) in a randomized, placebo-controlled clinical study with 120 subjects. However, the underlying pharmacological actions of MZRW for FC, are still largely unknown. We systematically analyzed the bioactive compounds of MZRW and mechanism-of-action biological targets through a novel approach called “focused network pharmacology.” Among the 97 compounds identified by UPLC-QTOF-MS/MS in MZRW extract, 34 were found in rat plasma, while 10 were found in rat feces. Hierarchical clustering analysis suggest that these compounds can be classified into component groups, in which compounds are highly similar to each other and most of them are from the same herb. Emodin, amygdalin, albiflorin, honokiol, and naringin were selected as representative compounds of corresponding component groups. All of them were shown to induce spontaneous contractions of rat colonic smooth muscle in vitro. Network analysis revealed that biological targets in acetylcholine-, estrogen-, prostaglandin-, cannabinoid-, and purine signaling pathways are able to explain the prokinetic effects of representative compounds and corresponding component groups. In conclusion, MZRW active components enhance colonic motility, possibly by acting on multiple targets and pathways.

Abstract
PURPOSE The evidence regarding the (cost-)effectiveness of sacral neuromodulation (SNM) in patients with therapy-resistant idiopathic slow-transit constipation is of suboptimal quality. The Dutch Ministry of Health, Welfare and Sports has granted conditional reimbursement for SNM treatment. The objective is to assess the effectiveness, cost-effectiveness, and budget impact of SNM compared to personalized conservative treatment (PCT) in patients with idiopathic slow-transit constipation refractory to conservative treatment. METHODS This study is an open-label, multicenter randomized controlled trial. Patients aged 14 to 80 with slow-transit constipation, a defecation frequency (DF) < 3 per week and meeting at least one other Rome-IV criterion, are eligible. Patients with obstructed outlet, irritable bowel syndrome, bowel pathology, or rectal prolapse are excluded. Patients are randomized to SNM or PCT. The primary outcome is success at 6 months (DF ≥ 3 a week), requiring a sample size of 64 (α = 0.05, β = 0.80, 30% difference in success). Secondary outcomes are straining, sense of incomplete evacuation, constipation severity, fatigue, constipation specific and generic quality of life, and costs at 6 months. Long-term costs and effectiveness will be estimated by a decision analytic model. The time frame is 57 months, starting October 2016. SNM treatment costs are funded by the Dutch conditional reimbursement program, research costs by Medtronic. CONCLUSIONS The results of this trial will be used to make a final decision regarding reimbursement of SNM from the Dutch Health Care Package in this patient group. TRIAL REGISTRATION This trial is registered at clinicaltrials.gov , identifier NCT02961582, on 12 October 2016.

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
Diarrhea is one of the most common complications following colectomy in patients with slow transit constipation (STC). Early postoperative diarrhea is usually treated with opioid agonists; however, to date, published data on the management of persistent diarrhea after colectomy for STC are scarce. Here, we report a case of severe diarrhea after a total colectomy with ileorectal anastomosis. One year after the surgery, the patient presented with persistent diarrhea. Treatment with a long-acting somatostatin analogue, lanreotide Autogel, was initiated. One month after the first injection of lanreotide Autogel the diarrhea was resolved. The patient's stool transit was markedly improved (type 4 or type 5 according to the Bristol Stool Chart compared to type 7 before the treatment), positively affecting the patient's quality of life (mean score of 2.1 on the Irritable Bowel Syndrome Quality of Life questionnaire compared to 3.9 before the treatment). This case report describes a successful use of lanreotide Autogel in a patient with persistent diarrhea after a total colectomy.

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
Chronic constipation is a considerable problem because it significantly affects the quality of a patient's life. Constipation can be diagnosed at every age and is more frequent in women and among the elderly. In epidemiological studies, its incidence is estimated at 2-27% in the general population. Chronic constipation may be primary or secondary. However, primary constipation (functional or idiopathic) can be classified into normal transit constipation, slow transit constipation, and pelvic outlet obstruction. In this review we make an attempt to present the current pathophysiological aspects and new therapeutic options for chronic idiopathic constipation, particularly highlighting the value of patient assessment for accurate diagnosis of the cause of the problem, thus helping in the choice of appropriate treatment.

Abstract
AIM We present an operating technique inspired from the Orr-Loygue mesh rectopexy adapted for laparoscopy, and detail the technical steps that differ from laparoscopic posterior suture rectopexy more commonly described in the paediatric literature. METHOD We present a retrospective study of all children who underwent a modified Orr-Loygue procedure for recurrent complete rectal prolapse from 1999 to 2012 after failure of conservative treatment. Pathological conditions, technical details of the procedure (excision of the Douglas pouch, use of a prerectal non-absorbable mesh to suspend the rectum to the presacral fascia and promontory avoiding any tension on the rectal wall) and postoperative results were reviewed. RESULTS Eight patients were included, median age 6.5 years (range, 2-17). Median symptoms duration before surgery was 14 months (range, 6-24). Four patients presented with associated pathological conditions: 1 neurological impairment (Williams-Beuren syndrome), 1 severe malnutrition (mental anorexia), 1 solitary rectal ulcer with frequent bleeding, 1 syringomyelic cavity in the spinal cord. All procedures were completed laparoscopically with a median operative time of 98 minutes (range, 80-125). Median hospital stay was 3.5 days (range, 2-5). No postoperative constipation or recurrence was reported during the median follow-up period of 6 years (range 2-13). CONCLUSION The laparoscopic modified Orr-Loygue mesh rectopexy is a simple operating technique, reproducible and efficient as surgical treatment of nonresolving recurrent complete rectal prolapse in children. To avoid postoperative constipation, it is important to perform a tension-free rectopexy which can be achieved by the use of a mesh to simply suspend and not "fix" the redundant rectosigmoid. Nonetheless, a greater number of patients as well as colorectal electromyography or anorectal manometry would be necessary to prove the absence of postoperative deleterious functional disorder.

Abstract
A cathartic colon is characteristic of slow transit constipation (STC), which can result following the long-term use of irritant laxatives. In the present study, the involvement of three opioid receptor subtypes (μ, MOR; δ, DOR; and κ, KOR), regulator of G protein signaling 4 (RGS-4) and β-arrestin-2 were investigated in the cathartic colon of rats. A rat model of a cathartic colon was established by feeding the animals with phenolphthalein, while normal rats were used as a control. The mRNA and protein expression levels of the opioid receptors, RGS-4 and β-arrestin-2 were detected in the rat colon using semi-quantitative reverse transcription polymerase chain reaction and western blot analysis, respectively. The rat model of a cathartic colon was successfully established using the phenolphthalein stimulus, and was shown to result in shrunken myenteric neurons and loose muscle fibers in the intestinal wall. The mRNA and protein expression levels of the three opioid receptor subtypes, RGS-4 and β-arrestin-2 were significantly higher in the cathartic colon group when compared with the levels in the normal control group (all P<0.01). With regard to the protein expression levels, MOR protein increased 2.4 fold, DOR expression increased 1.5 fold, KOR levels increased 1.5 fold, RGS-4 protein increased 3.5 fold and β-arrestin-2 expression increased 2.0 fold. Therefore, the expression levels of opioid receptors were found to increase in the cathartic colons of the rats, indicating that opioid receptors and downstream RGS-4 and β-arrestin-2 signaling may play an important role in the pathogenesis of STC.

Abstract
OBJECTIVE To compare the efficacy and safety of hand-assisted laparoscopic colectomy (HALC) and open colectomy (OC) for patients with slow transit constipation (STC). METHODS Data of patients with STC who underwent total colectomy from January 2008 to December 2012 were retrospectively reviewed after clinical evaluation and an exclusion of secondary causes. These patients were further divided into the HALC and OC groups. Patients' outcomes, including intraoperative and postoperative data on their recovery and complications were compared between the two groups. RESULTS A total of 68 patients with STC were finally enrolled in the study, including 32 in the HALC group and 36 in the OC group. The baseline characteristics did not significantly differ between the two groups. Compared with the OC group, patients in the HALC group had a shorter length of incision, a longer operative time and less blood loss volume. There was no conversion to OC for patients undergoing HALC and no intraoperative complications in both groups. Furthermore, after operation, patients in HALC group experienced less pain (3.4 ± 0.7 vs 4.8 ± 1.0), earlier first passage of flatus (58.3 ± 6.3 h vs 73.4 ± 13.0 h), shorter length of postoperative hospital stay (8.8 ± 1.2 days vs 11.3 ± 1.7 days) but higher medical cost (RMB 33 979 ± 3 135 vs RMB 29 828 ± 3 216). The overall postoperative complications and the satisfaction in defecation were comparable in the two groups. CONCLUSION HALC is a safe, minimally invasive and effective surgical alternative for treating STC, which is comparable to OC.

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.

BACKGROUND Some patients with Prader-Willi Syndrome (PWS) have symptoms of constipation, but bowel function in PWS has never been systematically evaluated. The aim of the present study was to describe colorectal function in PWS by means of validated techniques. METHODS Twenty-one patients with PWS (14 women, age 17-47 (median = 32)) were evaluated with the Rome III constipation criteria, stool diary, digital rectal examination, rectal diameter assessed from transabdominal ultrasound, and total gastrointestinal transit time (GITT) determined with radio-opaque markers. Results were compared with those of healthy controls. RESULTS Among PWS patients able to provide information for Rome III criteria, 8/20 (40%) fulfilled the criteria for constipation. Most commonly reported symptoms were a feeling of obstructed defecation (8/19, 42%), <3 defecations per week (8/17, 47%), straining during defecation (7/19, 37%) and lumpy or hard stools (6/19, 32%). Rectal diameter did not differ between PWS (median 3.56 centimeters, range 2.24-5.36) and healthy controls (median 3.42 centimeters, range 2.67-4.72) (p = 0.96), but more PWS patients (13/20; 65%) than healthy controls (3/25; 12%) (p < 0.001) had fecal mass in the rectum. Median GITT was 2.0 days (range 0.5-4.4) in PWS versus 1.6 (range 0.7-2.5) in the control group (p = 0.26). However, GITT was >3 days in 5/21 (24%) of PWS and none of the controls (p = 0.047). CONCLUSION Constipation is very common in PWS. Patients with PWS have an increased prevalence of prolonged GITT and palpable stools in the rectum at digital rectal examination.

Abstract
Colonic inertia is a frustrating motility disorder to patients, clinicians, and pathologists. The pathogenesis is largely unknown. The aims of this study were to: (1) characterize the expression of smoothelin, a novel smooth muscle-specific contractile protein expressed only by terminally differentiated smooth muscle cells, in the normal gastrointestinal (GI) tract; and (2) determine whether smoothelin is aberrantly expressed in patients with colonic inertia. A total of 57 resections of the normal GI tract (distal esophagus to left colon) were obtained from patients without GI motor dysfunction. Sixty-one colon resections were obtained from patients with a clinical diagnosis of colonic inertia. Smoothelin immunostaining was conducted on full-thickness tissue sections. In the nondysmotile controls, strong and diffuse cytoplasmic staining for smoothelin was observed in both the inner circular and outer longitudinal layers of the muscularis propria (MP) throughout the entire GI tract. The muscularis mucosae (MM) and muscular vessel walls were either completely negative or only patchily and weakly stained. The 1 exception to this pattern was observed in the distal esophagus, in which the MM was also diffusely and strongly stained. In cases with colonic inertia, a moderate to marked reduction of smoothelin immunoreactivity was observed in 15 of 61 (24.6%) colon resections, selectively seen in the outer layer of the MP. The data demonstrate that smoothelin is differentially expressed in the MP and MM of the normal GI tract and suggest that defective smoothelin expression may play a role in the pathogenesis of colonic inertia in a subset of patients.

Abstract
BACKGROUND Sacral neuromodulation (SN) is an emerging treatment for constipation. This review evaluates the mechanism of action, techniques, efficacy, and adverse effects of SN in the management of constipation. METHODS Electronic searches for studies describing the use of SN were performed in PubMed, MEDLINE and Embase. Abstracts were reviewed and full text copies of all relevant articles obtained. RESULTS Fifty-nine results were obtained on the initial searches. Ten studies discussed the results of SN in patients with constipation. A total of 225 temporary neuromodulations and 125 permanent implants were performed. Bowel diaries showed improvement in assessment criteria in more than 50% of patients on temporary neuromodulation and the results were maintained in approximately 90% of patients who underwent permanent implantation over medium to long-term follow-up. The rate of adverse effects was high, but the majority of them were related to electrode position. Improvements in transit studies and anorectal physiology after neuromodulation were noted in some studies. The recognized limitations included a lack of randomized studies and an inability to perform meta-analysis. CONCLUSION Sacral neuromodulation may be an effective treatment in selected patients with constipation and should be a part of the management repertoire. Improvement in defecatory frequency with temporary wire placement is a good predictor of subsequent response following permanent implant. Further research into predictive factors for success would improve patient selection.

Abstract
BACKGROUND Surgery is indicated for chronic constipation refractory to conservative therapy. The treatment of combined slow-transit constipation and obstructive defecation is controversial. OBJECTIVE The aim of the study is to describe the Jinling procedure and examine safety, effectiveness, and quality of life over 4 years of follow-up. DESIGN The study is a retrospective review of prospectively gathered data in a patient registry database. SETTINGS This investigation was conducted at a tertiary-care gastroenterology surgical center in China. PATIENTS The study included 117 consecutive patients with slow-transit constipation combined with obstructive defecation treated between January 2005 and December 2007. INTERVENTION The Jinling procedure modifies the classic procedure of subtotal colectomy with colorectal anastomosis by adding a new side-to-side cecorectal anastomosis to solve the coexistence of obstructive defecation and slow-transit constipation in one operation. MAIN OUTCOME MEASURES We measured morbidity and mortality rates, Wexner constipation scores, and Gastrointestinal Quality of Life Index at baseline and after 1, 6, 12, 24, 36 and 48 months of follow-up. RESULTS A total of 117 patients underwent the Jinling procedure, which was laparoscopically assisted in 56 patients (47.9%) and an open procedure in 61 patients (52.1%). Of the total, 72 patients (61.5%) had undergone previous surgical intervention without improvement. A total of 28 complications and adverse events were reported in 117 procedures, giving an overall morbidity rate of 23.9%; 23 patients (19.7%) had 1 or more events. Most complications were managed conservatively. A significant reduction in Wexner constipation score was observed from baseline (mean, 21.9) to 1 month (mean, 9.8), and the reduction was maintained at 48 months (mean 5.1; p < 0.001). Compared with baseline, significant overall improvements were also seen in gastrointestinal quality of life at 12, 24, and 48 months of follow-up (p < 0.01). LIMITATIONS This study did not include a comparison group. CONCLUSIONS Our clinical practice demonstrates that Jinling procedure is safe and effective for refractory slow-transit constipation associated with obstructive defecation, with minimal major complications, significant improvement of quality of life, and a high satisfaction rate after 4-year follow up.

Abstract
Chronic constipation is a common problem among women, is associated with anxiety and depression and can adversely affect quality of life (Mason et al, 2002). Chronic constipation is often unrelieved by simple laxatives, dietary manipulation or lifestyle modification, with other specialist treatment options being invasive and often not widely available. More recently attention has turned to newer prokinetic agents, such as prucalopride (Resolor®), which increase gut motility and intestinal transit, for the relief of chronic constipation. While these are not effective for everyone, there is evidence that prucalopride can increase bowel frequency, relieve bothersome symptoms associated with constipation and improve quality of life for women who have failed to achieve satisfactory relief from two other laxatives (National Institute for Health and Clinical Excellence).

Abstract
BACKGROUND Constipation is a common multifactorial gastrointestinal symptom with quality of life implications. Sacral neuromodulation has been used in the management of severe constipation with mixed results. The aim of this study was to review our experience of sacral neuromodulation as a treatment for chronic constipation and develop a chronic constipation management protocol. METHODS In patients with severe constipation, failure of conservative management including biofeedback and rectal irrigation were considered for neuromodulation. Temporary stimulation lead was placed in the sacral foramen of eligible patients and pre and post stimulation bowel diaries were compared. Patients with ≥50% improvement in bowel diaries had permanent implant. Patients were followed up at 2 and 4 weeks, 3, 6, and 12 months, and then yearly with bowel diaries. RESULTS Temporary neuromodulation wires were implanted in 21 patients (20 female). Significant bowel diary improvement was seen in 12 (57%) patients (p < 0.01). Eleven permanent implants have been performed. Improvement in symptoms was lost in one patient. No major side effects were observed. Three patients have had reoperations (one wire fracture, one reposition of battery, and one poor initial lead placement). Improvements in bowel diaries have been maintained over a median follow-up period of 38 months (18-62 months). CONCLUSION Sacral neuromodulation can provide long-term symptom relief in selected patients with severe constipation. Sacral neuromodulation should be incorporated into the treatment algorithm for chronic constipation.

Beyond hematoxylin and eosin: the importance of immunohistochemical techniques for evaluating surgically resected constipated patients. Tech Coloproctol 2011; 15:371-5. [PMID: 21766200 DOI: 10.1007/s10151-011-0721-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/16/2011] [Accepted: 06/30/2011] [Indexed: 12/18/2022]
Abstract
Chronic constipation requiring surgical ablation for intractability is often a frustrating condition from the pathologist's point of view. In fact, limiting the histological examination to only hematoxylin-eosin staining usually yields only the information that there are no abnormalities. By employing some simple and widely available immunohistochemical methods, discussed in this review, it is possible to gather data that may help in explaining the pathophysiological basis of constipation in these patients.

Chronic constipation: no more idiopathic, but a true neuropathological entity. GASTROENTEROLOGY AND HEPATOLOGY FROM BED TO BENCH 2011; 4:109-15. [PMID: 24834167 PMCID: PMC4017417] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Subscribe] [Scholar Register] [Received: 05/11/2011] [Accepted: 06/11/2011] [Indexed: 11/25/2022]
Abstract
Chronic constipation is still considered a functional or idiopathic disorder. However, in recent years there is evidence that its pathopysiological grounds may be actually due to a complex system of abnormalities of the enteric nervous system of these patients. In particular, as reported in this review, the enteric glial cells seem to be constantly involved in constipated patients, suggesting that (at least some forms of) constipation should be considered as true neuro-gliopathies.

Abstract
PURPOSE Failure to expel a 60-mL balloon on manometry and abnormal relaxation of anal sphincter on electromyographic testing are frequently used to diagnose pelvic floor dyssynergia. However, the relationship between these 2 test results and their relationship to defecography is poorly characterized. We aimed to describe this relationship and create a predictive model for pelvic floor dyssynergia on defecography. METHODS From March 2008 to April 2010 consecutive patients with symptoms suggestive of functional constipation were evaluated at our Pelvic Floor Disorders Center 125 and the results of their workups were collected prospectively. Sixty-three patients with pelvic floor dyssynergia on defecography were compared with 60 patients without dyssynergia in terms of manometry pressures, electromyographic text results, and balloon expulsion testing results (χ, t tests). RESULTS Of 125 patients meeting Rome II symptom criteria for constipation, 123 patients underwent defecography and, of these, 63 (51.2%) had evidence of pelvic floor dyssynergia. Patients with and without dyssynergia had a slight difference in mean resting pressures (62.8 mmHg vs 49.5 mmHg, P = .02) and no discernable differences in rectal sensitivity and compliance: first sensation (56.5 vs 62.5, P = .34) and maximum tolerated volume (164.2 vs 191.2, P = .09). It appeared that abnormalities in electromyographic relaxation and balloon expulsion occurred in the same patients: 84.1% of patients with abnormal electromyographic results also did not expel the balloon. However, the presence of these abnormalities, in isolation or together, did not predict the presence of dyssynergia on defecography. CONCLUSION Normal electromyographic results or the ability to expel a 60-mL balloon does not exclude the presence of pelvic floor dyssynergia on defecography. It is unclear which of these 3 tests should be used to guide the recommendation for (and to then measure response to) biofeedback.
