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
RATIONALE Slow transit constipation (STC) is a common disease of which the etiology is still not clear. Multiple hypotheses have been proposed to explain STC, including autonomic neuropathy, disorders of the enteric nervous system and so forth. Morphological abnormalities of the enteric nerves of the colon in patients with STC have been extensively reported, while there have been no morphological reports focusing on extrinsic extramural fibers from the pelvic plexus to the distal colon (i.e., pelvic parasympathetic colonic nerve) in patients with STC. PATIENT CONCERNS Whether morphological changes of pelvic parasympathetic colonic nerve coexist with abnormalities of the enteric nerves of the colon in the patient with STC. DIAGNOSIS Slow transit constipation (STC). INTERVENTIONS The patient with STC underwent a partial colectomy (sigmoid colon and partial descending colon). The fibers of the myenteric plexuses within the removed colon and the myelinated fibers of the pelvic parasympathetic colonic nerve were observed under optical and electron-microscope. OUTCOMES The fibers of the myenteric plexuses showed vacuolated degeneration between the muscularis propria layer under optical microscope. Myelinated fibers of the pelvic parasympathetic colonic nerve showed obvious vacuolated degeneration under electron-microscopic examination. LESSONS Such a simultaneous neuropathy in both myenteric plexuses and extrinsic extramural nerves has not been documented previously. Our finding supports the notion that neuropathy remains the most plausible explanation for STC, in which nerve dysfunction might occur by way of a degenerative process.

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

Abstract
Peptide YY (PYY) is affected in several gastrointestinal diseases and disorders. Changes in PYY appear to be an adaptive response to alterations in pathophysiological conditions caused by the disease. This applies to gastrointestinal diseases/disorders such as irritable bowel syndrome, inflammatory bowel disease, celiac disease, systemic sclerosis, and post-intestinal resection. By contrast, the changes in PYY in chronic idiopathic slow transit constipation (CST) seem to be of a primary nature, and may be one etiological factor of the disease. Abnormalities in PYY seem to contribute to the development of symptoms present in irritable bowel syndrome, inflammatory bowel disease, gastroenteropathy in long-standing diabetes and CST. The changes in PYY could, however, be favorable in some gastrointestinal disorders such as celiac disease, systemic sclerosis and post-intestinal resection state. Investigating changes in PYY in gastrointestinal diseases/disorders could be beneficial in clinical practice, where a receptor agonist or an antagonist can be used as a drug, depending on the condition. Similar to other neuroendocrine peptides/amines of the gut, PYY has broad physiological/pharmacological effects: it can bind to and activate several receptors with independent actions. Thus, in order to use PYY as a drug, receptor-specific agonists or antagonists need to be developed.

Abstract
BACKGROUND Clinical studies show that disturbed colonic motility induced by extrinsic nerves damage is restored over time. We studied whether 5-HT3 and 5HT4 receptors are involved in mediating the adaptive mechanisms following parasympathetic denervation. METHODS Parasympathetic denervation of the entire colon was achieved by bilateral pelvic nerve transection and truncal vagotomy in rats. Colonic transit was measured by calculating the geometric center (GC) of 51Cr distribution. Expression of 5-HT3 and 5HT4 receptor mRNA was determined by real time RT-PCR. RESULTS Parasympathetic denervation caused a significant delay in colonic transit (GC=4.36) at postoperative day (POD) 1, compared with sham operation (GC=6.31). Delayed transit was gradually restored by POD 7 (GC=5.99) after the denervation. Restored colonic transit was antagonized by the administration of 5-HT3 and 5HT4 receptors antagonists at POD 7. 5-HT3 and 5HT4 receptors mRNA expression were significantly increased in the mucosal/submucosal layer at POD 3 or POD 7, whereas no significant difference was observed in the longitudinal muscle layers adherent with the myenteric plexus (LMMP). CONCLUSIONS It is suggested that up-regulation of 5-HT3 and 5-HT4 receptors expression in the mucosal/submucosal layer is involved to restore the delayed transit after the parasympathetic denervation in rats.

Abstract
BACKGROUND Some patients with severe slow-transit constipation may benefit from subtotal colectomy, but there is no consensus on standard operative mode. The aim of the study was to compare the functional outcomes of subtotal colectomy with cecorectal anastomosis (CRA) with those of subtotal colectomy with ileosigmoidal anastomosis (ISA) in patients with severe slow-transit constipation. METHODS Records of 79 patients who received preoperative investigation to confirm slow transit at our institution from 1989 to 2004 and subsequently received colectomy with CRA (n = 34) or colectomy with ISA (n = 45) were reviewed. The mean follow-up was 2 years (range 1-15). RESULTS Postoperative defecation frequency increased and symptoms such as bloating and abdominal pain decreased in both groups. More CRA patients than ISA patients experienced persistent constipation and continued using laxatives or enemas at the 12-month follow-up. More ISA patients (93.3%) than CRA patients (73.5%) were satisfied with the procedure, whereas some patients in both groups complained of excessively high stool frequency and fecal incontinence. CONCLUSION Both CRA and ISA procedures increase the number of bowel movements; however, ISA results in higher defecation frequency, less use of laxatives and enemas, and higher patient satisfaction.

Abstract
Chronic constipation is a common disorder manifested by a variety of symptoms. Assessments of colonic transit and anorectal functions are used to categorize constipated patients into three groups, i.e., normal transit or irritable bowel syndrome, pelvic floor dysfunction (i.e., functional defaecatory disorders) and slow transit constipation. 'Slow transit' constipation is a clinical syndrome attributed to ineffective colonic propulsion and/or increased resistance to propagation of colonic contents. Defaecatory disorders are caused by insufficient relaxation of the pelvic floor muscles or a failure to generate adequate propulsive forces during defaecation. Colonic transit is often delayed in patients with functional defaecatory disorders. Normal and slow transit constipation are generally managed with medications; surgery is necessary for a minority of patients with slow transit constipation. Functional defaecatory disorders are primarily treated with pelvic floor retraining using biofeedback therapy.

Abstract
Slow transit constipation has been traditionally considered and classified as a functional disorder. However, clinical and manometric evidence has been accumulating that suggests how most of the motility alterations in STC might be considered of neuropathic type.In addition, further investigations showed that subtle alterations of the enteric nervous system, not evident to conventional histological examination, may be present in these patients. In the present article we will discuss these evidences, and will try to put them in relation with the abnormal motor function of the large bowel documented in this pathological condition.

Abstract
Diagnostic tools for paediatric chronic constipation have been limited, leading to over 90% of patients with treatment-resistant constipation being diagnosed with chronic idiopathic constipation, with no discernible organic cause. Work in our institution suggests that a number of children with intractable symptoms actually have slow colonic transit leading to slow transit constipation. This paper reviews recent data suggesting that a significant number of the children with chronic treatment-resistant constipation may have organic causes (slow colonic transit and outlet obstruction) and suggests new approaches to the management of children with chronic treatment-resistant constipation.

Abstract
OBJECTIVE Small bowel dysmotility has previously been demonstrated in some patients with slow transit constipation (STC), suggesting a generalized intestinal disorder. However, no study has addressed whether the incidence of small intestinal dysfunction differs between subgroups of patients in this heterogeneous population. Using appropriate methodology, we aimed to determine prospectively the proportion of individuals with abnormal small bowel motility, and to assess whether heterogeneity in terms of pattern of colonic transit delay (based on (111)In diethylene-triamine-pentaacetic acid (DTPA) isotope scintigraphy), or mode of onset (based on clinical history) is of importance. METHODS Thirty-seven patients with STC underwent 24-h ambulatory jejunal manometry; data were compared with those obtained in 38 healthy controls. Automated quantitative analysis of seven variables of the nocturnal migrating motor complex was performed, to assess whether differences existed between groups, and whether individual patients had evidence of small intestinal dysmotility, defined as two or more measures of migrating motor complex variables outside the normal range. Four variables differed significantly between STC patients and controls: in phase III, propagation was slower, duration was longer, and contraction amplitude was higher; in phase II, contraction frequency was increased. Seven of 24 patients with a generalized pattern of colonic transit delay had abnormal small bowel motility compared with none of 13 with a left-sided delay (p < 0.04). These included four patients with chronic idiopathic symptoms and three with acquired symptoms. Approximately one third of patients with a generalized delay in colonic transit had evidence of jejunal enteric neuromuscular dysfunction. Individual patients with a left-sided colonic delay did not satisfy the criteria for nocturnal small bowel dysmotility, but as a group, some differences were noted from controls. In contrast to previous reports, evidence of generalized enteric dysmotility may be present irrespective of the mode of onset.

Abstract
The changes in PYY in several gastrointestinal disorders and their possible clinical implications are reviewed. The changes in PYY seem to be an adaptive response to alterations in the patho-physiological condition caused by the disease. This becomes evident in gastrointestinal disorders such as diabetes gastroenteropathy, inflammatory bowel diseases, celiac disease, systemic sclerosis and post-intestinal resection state. On the other hand, changes in PYY in chronic idiopathic slow transit constipation appear to be primary and could be one of the etiologic factors of the disease. PYY does not seem to be involved in colorectal carcinoma. Although gastrointestinal dysmotility in neuro-muscular diseases is evident, PYY is not affected. The changes in PYY in gastrointestinal disorders could be beneficial in clinical practice. Thus, in cases where an increase or decrease in PYY is desirable, a diet that increases or decreases PYY synthesis and release can be followed, or a receptor agonist or antagonist can be utilized.

Abstract
Slow transit constipation is a clinical syndrome predominantly affecting young women, characterized by constipation and delayed colonic transit, occasionally associated with pelvic floor dysfunction. The disorder spans a spectrum of variable severity, ranging from patients who have relatively mild delays in transit but who are otherwise indistinguishable from irritable bowel syndrome patients at one extreme, to patients with colonic inertia or chronic megacolon at the other extreme. Potential mechanisms for impaired colonic propulsion include fewer colonic HAPCs or a reduced colonic contractile response to a meal. The cause of the syndrome is unclear. The treatment is primarily medical; surgery is reserved for patients with severe disease or colonic inertia. Recognition and treatment of pelvic floor dysfunction is crucial for patients treated medically or surgically. Collaborative studies are necessary to determine the pathophysiology of this disorder and to ascertain the efficacy of novel prokinetic agents.

Abstract
BACKGROUND Colonic transit has not been compared between patients with slow-transit constipation (STC) arising de novo (idiopathic) and those whose symptoms followed pelvic surgery or childbirth (acquired). METHODS In 48 women, with either idiopathic (n = 36) or acquired (n = 12) STC, 111In-radiolabelled diethylene-triamine penta-acetic acid colonic scintigraphy was performed to determine patterns of delay (generalized or left sided), the 'severity' of transit disturbance between subgroups, and the association with age or duration of symptoms. Results were compared with those in healthy women. Patterns of colonic transit disturbance were assessed using previously defined criteria. In those with a generalized delay, variables reflecting the overall rate of isotope progression throughout the colon were calculated: gradient of geometric centre of isotope progression and estimated evacuation time of the isotope. RESULTS The pattern of transit delay was similar between the subgroups, but the 'severity' of the transit abnormality was significantly worse in those with chronic idiopathic symptoms. In the chronic idiopathic STC subgroup only, there was a significant correlation between both age and duration of symptoms and severity of transit disturbance. CONCLUSION This study demonstrates that differences in colonic transit exist between subgroups of patients with STC. These might be explained by differences in duration of symptoms or differences in aetiology.

Abstract
OBJECTIVE The outcome of surgery in patients with slow transit constipation (STC) is unpredictable. This may reflect clinical and physiological heterogeneity within this group of patients. This study attempts to identify subgroups of patients with STC according to clinical history, and compares the pathophysiological findings between the two largest: including patients with chronic idiopathic STC, and those with symptoms acquired after pelvic surgery or childbirth (post-pelvic intervention STC). PATIENTS AND METHODS Review of clinical and gastrointestinal pathophysiological findings of 122 consecutive patients with slow colonic transit. RESULTS Six subgroups of patients were defined according to the time and nature of onset of symptoms. Pathophysiological comparison of the two main groups: chronic idiopathic STC (n=65 (53%)) and post-pelvic intervention STC (n=22 (18%)), yielded three main conclusions: (i) the pattern of colonic transit is similar in both groups, i.e. predominantly (approximately 70%) generalized; (ii) the prevalence of a rectal evacuatory disorder is significantly higher in patients with post-pelvic intervention STC (77% vs 32%, P=0.004); and (iii) small bowel motility disturbances occur in both groups (overall 48%), and are therefore not limited to patients with chronic idiopathic STC. CONCLUSION There are pathophysiological similarities and differences between the main two subgroups of STC. Such findings may help our understanding of the pathogenesis and have implications in the future management of these patients.

Abstract
Slow transit constipation is a severe condition of gut dysmotility that predominantly affects young women and may result in surgical intervention. Current medical treatments for STC are often ineffective, and the outcome of surgery is unpredictable. STC was first described almost a century ago. Since this time, progress in improving therapy for this condition has been complicated by a lack of understanding of the aetiology, and great variation in the methods and criteria used for the study of patients with this debilitating disorder. It is difficult to find unequivocal data, and harder still to give a definitive picture of the cause or causes of STC. Here we consider the evidence for various aetiologies of STC, in the light of the physiological and pathological findings.

Abstract
The motility disorders in patients with slow-transit constipation have been attributed to a disturbance in the peptidergic innervation of the colonic enteric nervous system. The nature of this disturbance is, however, controversial. In the present study 7 patients with long-standing severe slow- transit constipation were included, and normal tissues from the colon of 6 patients, which had undergone colonectomy because of polyp, chronic diverticulitis, prolapsis and volvulus were used as controls. The concentrations of several neuroendocrine peptides were measured in tissue extracts by radioimmuno-assays. The level of pancreatic polypeptide was high in 2 patients and low in one patient. Peptide YY level was high in 3 patients and low in one patient, and that of neuropeptide Y was high in 4 patients. Somatostatin and vasoactive intestinal polypeptide levels were high in 3 patients and substance P concentration was low in 3 patients. Neurotensin level was high in one patient and low in another patient. Galanin concentration was low in 2 patients and high in one patient. Gastrin-releasing peptide level was high in one patient and that of enkephalin was high in 2 patients. All patients had altered concentrations of several neuroendocrine peptides except one, who had only a low level of galanin. It is concluded that patients with slow-transit constipation have disturbed neuroendocrine peptides in common, though the nature of this disturbance varies between patients and in most patients several neuroendocrine peptides were affected. This may explain the controversial results obtained in previous studies.

Abstract
PURPOSE Constipation is a common complaint; however, clinical presentation varies with each individual. The aim of this study was to assess a standard scoring system for evaluation of constipated patients. MATERIALS AND METHODS All consecutive patients with idiopathic constipation who were referred for anorectal physiologic testing were assessed. A subjective constipation score was calculated based on a detailed questionnaire that included over 100 constipation-related symptoms. Based on the questionnaire, scores ranged from 0 to 30, with 0 indicating normal and 30 indicating severe constipation. The constipation score was then compared with the objective findings of the physiology tests, which include colonic transit time (CTT), anal manometry (AM), cinedefecography (CD), and electromyography (EMG). Colonic inertia was defined as diffuse marker delay on CTT without evidence of paradoxical contraction on AM, CD, or EMG. Pelvic outlet obstruction was defined as paradoxical puborectalis contraction, rectal prolapse or rectoanal intussusception, rectocele, or sigmoidocele. RESULTS A total of 232 patients (185 females and 47 males) of a mean age of 64.9 (range, 14-92) years were evaluated. All patients had a score of more than 15; on evaluation of the significance of different symptoms in the constipation score with the Pearson's linear correlation test, 8 of 18 factors were identified as significant (P < 0.05). These factors included frequency of bowel movements, painful evacuation, incomplete evacuation, abdominal pain, length of time per attempt, assistance for evacuation, unsuccessful attempts for evacuation per 24 hours, and duration of constipation. All 232 patients had objective obstruction attributable to one or more of the following causes: paradoxical puborectalis contraction (81), significant rectocele or sigmoidocele (48), rectoanal intussusception (64), and rectal prolapse (9). CONCLUSION The proposed constipation scoring system correlated well with objective physiologic findings in constipated patients to allow uniformity in assessment of the severity of constipation.
