Abstract
BACKGROUND Direct colonic electrical stimulation may prove to be a treatment option for specific motility disorders such as chronic constipation. The aim of this study was to provoke colonic contractions using electrical stimulation delivered from a battery-operated device. METHODS Electrodes were inserted into the caecal seromuscular layer of eight anaesthetized pigs. Contractions were induced by a neurostimulator (Medtronic 3625). Caecal motility was measured simultaneously by video image analysis, manometry and a technique assessing colonic transit. RESULTS Caecal contractions were generated using 8-10 V amplitude, 1000 micros pulse width, 120 Hz frequency for 10-30 s, with an intensity of 7-15 mA. The maximal contraction strength was observed after 20-25 s. Electrical stimulation was followed by a relaxation phase of 1.5-2 min during which contractions propagated orally and aborally over at least 10 cm. Spontaneous and stimulated caecal motility values were significantly different for both intraluminal pressure (mean(s.d.) 332(124) and 463(187) mmHg respectively; P < 0.001, 42 experiments) and movement of contents (1.6(0.9) and 3.9(2.8) mm; P < 0.001, 40 experiments). CONCLUSION Electrical stimulation modulated caecal motility, and provoked localized and propagated colonic contractions.

Abstract
OBJECTIVE Patients with slow transit constipation who do not respond satisfactorily to common medical treatment are considered candidates for colectomy. The present observational long term study was designed to assess outcome after surgery. METHOD Twenty consecutive patients were treated by colectomy for slow transit constipation between 1996 and 2004. Preoperative and postoperative data were reviewed by using our institutional database. A questionnaire including validated scoring systems and questions about complications and subsequent surgical interventions was sent to all available patients. RESULTS Three patients (15%) died perioperatively. Median long term follow up was 84 months. Ten patients (50%) needed further operations after colectomy: Three patients (15%) had surgery during the early postoperative period, seven patients (35%) during follow up. A total of 31 operations had to be performed in these patients. Twelve patients (86%) responded to the questionnaires. Their median Wexner constipation score was 11.5 (range 8-23). Six patients fulfilled the Rome II criteria for constipation. The median Vaizey incontinence score was 7.5 (range 0-22). The median GIQLI showed 80 points (range 32-129). CONCLUSION Morbidity and mortality rate after colectomy were inadmissibly high. Taking into account the poor functional results, we cannot recommend colectomy for slow transit constipation.

Abstract
Fecal continence is a complex bodily function, which requires the interplay of sensation, rectal capacity, and anal neuromuscular function. Fecal incontinence affects approximately 2% of the population and has a prevalence of 15% in elderly patients. Constipation is one of the most common gastrointestinal disorders. The variety of symptoms and risk factors suggest a multifactorial origin. Before any invasive intervention, the surgeon should have a thorough understanding of the etiology of these conditions. Appropriate medical management can improve symptoms in the majority of patients. Surgery is indicated when all medical possibilities are exhausted. This review discusses the most used surgical procedures emphasizing the latest experiences. Sacral nerve stimulation (SNS) is a promising option for patients with fecal incontinence and constipation. The procedure affords patients improved continence and quality of life. The mechanism of action is still poorly understood. This treatment has been used before in other more invasive surgical procedures or even after their failure to improve patients' symptoms and avoid a definitive stoma.

Abstract
BACKGROUND AND AIMS Total abdominal colectomy with ileorectal anastomosis (TAC-IRA) is recommended widely for the patients with severe, refractory slow transit constipation (STC). Subtotal colectomy with end-to-end antiperistaltic cecorectal anastomosis (Sarli procedure), an alternative for STC, has been paid particular attention. The purpose of this study was to retrospectively compare alterations of clinical functions and qualities of life between TAC-IRA and Sarli procedure. METHODS Seventeen patients with STC who underwent Sarli procedure and 20 patients with STC who underwent TAC-IRA were chosen for this study. Patient characteristics, operative data, postoperative data, alterations of clinical function, and quality of life were compared. The gastrointestinal quality of life index (GIQLI) survey was used to evaluate postoperative qualities of life. RESULTS At the mean 4-year follow-up (range 2-6 years), the frequency of daily bowel movement in the Sarli group was significantly less than that in the TAC-IRA group (2.4 +/- 0.9 vs. 3.4 +/- 0.8; P = 0.0014), and the Wexner continence scores were significantly lower in the Sarli group compared to the TAC-IRA group (4.3 +/- 1.8 vs. 5.8 +/- 1.9; P = 0.0223). However, the GIQLI score in Sarli group was higher than the TAC-IRA group (119.8 +/- 7.5 vs. 111.1 +/- 12.0, P = 0.0455). Post subtotal colectomy barium enema showed a sign of "reservoir" at the residual ascending colon and cecum. CONCLUSIONS Compared to the TAC-IRA, subtotal colectomy with end-to-end antiperistaltic cecoproctostomy for appropriately selected patients with STC resulted in relief of constipation, satisfactory functional outcome, and improved qualities of life.

Abstract
BACKGROUND Surgical outcome and quality of life (QOL) following perineal proctectomy for rectal prolapse remain poorly documented. METHODS From 1994 to 2004, patients with full-thickness rectal prolapse were treated exclusively with perineal proctectomy independent of age or comorbidities. Subjective patient assessments and recurrences were determined retrospectively from hospital and clinic records. Consenting patients completed the gastrointestinal quality of life index (GIQLI). RESULTS Perineal proctectomy was performed in 103 consecutive patients with a median age of 75 years (range 30-94). Most patients underwent concurrent levatorplasty (anterior 85.8%, posterior 67.9%). Durable results were obtained in all patients; the recurrence rate was 8.5% over a mean follow-up of 36 months. Preoperatively, 75.5% of patients reported fecal incontinence, and 32.1% had obstructed defecation. Incontinence significantly improved post-proctectomy (41.5%, p < 0.001), as did constipation (10.4%, p < 0.001). GIQLI respondents reported satisfaction following proctectomy with 63% scoring within one standard deviation of healthy controls. Patients with recurrent prolapse reported a lower QOL. Risk factors for recurrence included duration of prolapse, need for posterior levatorplasty, and prior anorectal surgery. CONCLUSIONS Perineal proctectomy provides significant relief from fecal incontinence and obstructive symptoms caused by rectal prolapse, with an acceptable recurrence rate and low morbidity.

Abstract
Constipation is a common gastrointestinal complaint that can cause significant physical and psychosocial problems. It has been categorized as slow transit constipation, normal transit constipation, and obstructed defecation. Both the definition and pathophysiology of constipation are unclear, but attempts to describe each of the three types have been made. Slow transit constipation, a functional colonic disorder represents approximately 15 to 30% of constipated patients. The theorized etiologies are disorders of the autonomic and enteric nervous system and/or a dysfunctional neuroendocrine system. Slow transit constipation can be diagnosed with a complete history, physical exam, and a battery of specific diagnostic studies. Once the diagnosis is affirmed and medical management has failed, there are several treatment options. Biofeedback, sacral nerve stimulation, segmental colectomy, and subtotal colectomy with various anastomoses have all been used. Of those treatment options, a subtotal colectomy with ileorectal anastomosis is the most efficacious with the data to support its use.

Abstract
BACKGROUND The aim of the study was to evaluate the effectiveness of subtotal colectomy with cecorectal anastomosis (SCCA) in the treatment of slow-transit constipation, not just in terms of symptom resolution but also the overall impact on patients' quality of life. METHODS Between 1991 and 2005, 43 patients underwent SCCA at our institution, 22 for slow-transit constipation (STC) and 21 for other types of colic diffuse disease (non-slow-transit constipation: NSTC), the latter being considered controls. A total of 29 patients (17 affected by STC) were administered a 50-item telephonic questionnaire, including the Gastrointestinal Quality of Life Index (GIQLI), the Wexner constipation and incontinence scale (WC, WI), and individual willingness to repeat the procedure. Questionnaire data and other parameters such as age, sex, length of follow-up, complications, and length of hospital stay were analyzed and compared, in order to evaluate possible correlations between the parameters and their related impact on quality of life, procedural effectiveness in terms of symptomatic regression, qualitative differences related to pathology (constipation versus non-constipation), and surgical approach (laparotomy versus video-laparo-assisted procedure). RESULTS There were no procedure-related deaths in this series (mortality: 0%); however, we found two complications in the STC group (9.1%), one requiring reoperation. The GIQLI mean score for the STC group was 115.5 +/- 20.5 (mean score for healthy people 125.8 +/- 13), and the WC mean score passed from a preoperative value of 20.3 to a postoperative value of 2.6. Regression analysis revealed a significant correlation between GIQLI and urgency and abdominal pain, and abdominal pain correlated significantly with pathology (STC). A high number of patients (88.2% in STC) expressed a willingness to repeat the procedure given the same preoperative conditions. CONCLUSIONS Comparing our results to those of the most homogeneous literature data, SCCA does not appear to be inferior to subtotal colectomy with ileorectal anastomosis (IRA) in terms of therapeutic effectiveness, postoperative mortality and morbidity, or overall impact on quality of life.

Abstract
Electrical stimulation of the gastrointestinal (GI) tract is an attractive concept. Since these organs have their own natural pacemakers, the electrical signals they generate can be altered by externally delivering electric currents by intramuscular, serosal, or intraluminal electrodes to specific sites in the GI tract. This article reviews the advances in electrical stimulation of the GI tract by describing various methods of GI electrical stimulation and their peripheral and central effects and mechanisms; updating the status of GI electrical stimulation in the clinical settings of gastroparesis, obesity, fecal incontinence, and constipation; and predicting future directions and developments of GI electrical stimulation technology and their areas of possible clinical applications.

Abstract
BACKGROUND Colectomy with ileorectal anastomosis for slow transit constipation (STC) is being challenged by other operations, such as segmental resections. The importance of preoperative anorectal physiology testing may therefore be increased. The aim of this study was to identify anorectal abnormalities in patients with STC, which may influence the surgical approach. METHODS Fifty consecutive patients with STC (43 women; median age, 49 years) and 28 controls (23 women; median age, 50 years) were examined with anorectal manovolumetry. Anal pressures and rectal volumes were recorded, at stepwise rectal distension. RESULTS Anal resting pressure was lower in patients (median, 54 cm H(2)O; range, 22-130) than in controls (median, 68 cm H(2)O; range, 35-100) (p<0.05). Squeeze pressure tended to be lower in patients (median, 147 cm H(2)O; range, 53-382) than in controls (median, 177 cm H(2)O; range, 65-423) (p=0.09). Rectal sensory thresholds did not differ significantly between patients and controls, although 10 patients had a threshold for filling above the 95(th) percentile of controls. Rectal compliance was increased in patients in the pressure interval 5-35 cm H(2)O (p<0.05-0.01). The threshold and amplitude of the recto-anal inhibitory reflex did not differ significantly, but the recovery of resting pressure after eliciting the reflex was lower in patients than in controls in the pressure interval 10-50 cm H(2)O (p<0.05-0.001). CONCLUSIONS More than half of the patients with STC deviated in some parameter. An impaired internal sphincter function and increased rectal compliance were seen. One fifth of the patients had impaired rectal sensation.

Abstract
Slow-transit constipation is characterized by delay in transit of stool through the colon, caused by either myopathy or neuropathy. The severity of constipation is highly variable, but may be severe enough to result in complete cessation of spontaneous bowel motions. Diagnostic tests to assess colonic transit include radiopaque marker or radioisotope studies, and intraluminal tests (colonic and small bowel manometry). Most patients with functional constipation respond to laxatives, but a small proportion are resistant to this treatment. In some patients biofeedback is helpful although the mechanism by which this works is still uncertain. Other patients are resistant to all conservative modes of therapy and require surgical intervention. Extensive clinical and physiological preoperative assessment of patients with slow colonic transit is essential before considering surgery, including an assessment of small bowel motility and identification of coexistent obstructed defecation. The psychological state of the patient should always be taken into account. When surgery is indicated, subtotal colectomy and ileorectal anastomosis is the operation of choice. Segmental colonic resection has been reported in a few patients, but methods of identifying the affected segment need to be developed further. Less invasive and reversible surgical options include laparoscopic ileostomy, antegrade colonic enema and sacral nerve stimulation.

Abstract
BACKGROUND The impact of constipation on quality of life (QoL) may vary in different cultural or national settings. AIM We studied QoL in a multinational survey to compare different social and demographic groups with and without constipation (defined according to Rome III criteria) and to detect country-specific differences among the groups studied. METHODS Health-related QoL (HRQoL) was assessed with the Short Form 36 (SF-36) questionnaire in 2870 subjects in France, Germany, Italy, UK, South Korea, Brazil and USA. Results Respondents were mainly middle-aged, married or living together and part- or full-time employed. General health status, measured by the SF-36 questionnaire, was significantly worse in the constipated vs. non-constipated populations. RESULTS were comparable in all countries. QoL scores correlated negatively with age. Constipated women reported more impaired HRQoL than constipated men. Brazilians were most affected by constipation as to their social functioning (35.8 constipated vs. 51.3 non-constipated) and general health perception (29.4 constipated vs. 54.4 non-constipated). CONCLUSIONS There are significant differences in HRQoL between constipated and non-constipated individuals and a significant, negative correlation between the number of symptoms and complaints and SF-36 scores. The study detected a correlation of constipation with QoL and the influence of social and demographic factors on HRQoL in constipated people.

Abstract
AIM: To evaluate the results of sub total colectomy with cecorectal anastomosis (STC-CRA) for isolated colonic inertia (CI).
METHODS: Fourteen patients (mean age 57.5 ± 16.5 year) underwent surgery for isolated CI between January 1986 and December 2002. The mean frequency of bowel motions with the aid of laxatives was 1.2 ± 0.6 per week. All subjects underwent colonoscopy, anorectal manometry, cinedefaecography and colonic transit time (CTT). CI was defined as diffuse markers delay on CTT without evidence of pelvic floor dysfunction. All patients underwent STC-CRA. Long-term follow-up was obtained prospectively by clinical visits between October 2005 and February 2006 at a mean of 10.5 ± 3.6 years (range 5-16 years) during which we considered the number of stool emissions, the presence of abdominal pain or digitations, the use of pain killers, laxatives and/or fibers. Patients were also asked if they were satisfied with the surgery.
RESULTS: There was no postoperative mortality. Postoperative complications occurred in 21.4% (3/14). At the end of follow-up, bowel frequency was significantly (P < 0.05) increased to a mean of 4.8 ± 7.5 per day (range 1-30). One patient reported disabling diarrhea. Two patients used laxatives less than three times per month without complaining of what they called constipation. Overall, 78.5% of patients would have chosen surgery again if necessary.
CONCLUSION: STC-CRA is feasible and safe in patients with CI achieving 79% of success at a mean follow-up of 10.5 years. A prospective controlled evaluation is warranted to verify the advantages of this surgical approach in patients with CI.

Abstract
Serotonin (5-HT) is most commonly thought of as a neurotransmitter in the central nervous system. However, the predominant site of serotonin synthesis, storage, and release is the enterochromaffin cells of the intestinal mucosa. Within the intestinal mucosa, serotonin released from EC cells activates neural reflexes associated with intestinal secretion, motility, and sensation. Two important receptors for serotonin that are located in the neural circuitry of the intestines are the 5-HT(3) and 5-HT(4) receptors; these are the targets of drugs designed to treat gastrointestinal disorders. 5-HT(3) receptor antagonists are used to treat nausea and emesis associated with chemotherapy and for functional disorders associated with diarrhea. 5-HT(4) receptor agonists are used as promotility agents to promote gastric emptying and to alleviate constipation. Because of the importance of serotonin in normal gut function and sensation, a number of studies have investigated potential changes in mucosal serotonin signaling in pathologic conditions. Despite the inconsistencies in the current literature, changes in serotonin signaling have now been demonstrated in inflammatory bowel disease, irritable bowel syndrome, postinfectious irritable bowel syndrome, and idiopathic constipation. Emerging evidence has led to many contradictory theories regarding serotonin signaling and its roles in the pathology of gut disorders. This review summarizes the current medications affecting serotonin signaling and provides an overview of our current knowledge of the changes in serotonin that occur in pathologic conditions.

Abstract
Patients with intractable chronic constipation should be evaluated with physiologic tests after structural disorders and extracolonic causes have been excluded. Conservative treatment options should be tried excessively. If surgery is indicated subtotal colectomy with IRA is the treatment method of choice. However, segmental resection may be a good option for isolated megasigmoid, sigmoidocele or recurrent sigmoid volvulus. In general patients with GID should not be offered any surgical options because of their anticipated poor results. Moreover, patients with psychiatric disorders should be actively discouraged from resection as they tend to have poorer prognosis. Patients must be counseled that preoperative pain and/or bloating will likely persist even if surgery normalizes bowel frequency. Patients with associated problems may be better served by having a stoma without resection as both a therapeutic maneuver and a diagnostic trial. Colectomy is no option to treat pain and/or abdominal bloating.

Abstract
PURPOSE This study was designed to evaluate patient self-reported outcome of the Malone antegrade continent enema at a single institution in patients suffering from severe defecatory disorders. METHODS A total of 18 patients (15 females; median age, 31 (range, 12-63) years) underwent a Malone antegrade continent enema (August 1999 to September 2004). The Malone antegrade continent enema technique has been previously described; however, in this series emphasis was placed on method appendix tunneling. Patients' charts were reviewed and follow-up telephone interviews were conducted. Indications for Malone antegrade continent enema were chronic constipation (n = 12), intractable fecal incontinence (n = 5), or both (n = 1). The underlying pathology included neurogenic (n = 2), congenital (n = 4), postsurgery-related (n = 4), irritable bowel syndrome (n = 6), and megarectum (n = 2). The appendix (n = 17) or cecum (n = 1) was used as a conduit. RESULTS The mean follow-up was 18.5 (range, 3-67) months. Fourteen patients (78 percent) still use the Malone antegrade continent enema routinely and report good functional outcome. Three patients (20 percent) required stoma creation as subsequent alternate treatment. A total of 10 patients experienced 12 complications: 3 perioperative (infections) and 9 postoperative Malone antegrade continent enema use/nonuse complications (4 stomal orifice strictures, 2 fecal impactions, 2 appendiceal perforations, and 1 irrigation catheter knot). No patient experienced leakage from the appendiceal stoma. During the follow-up interval, one patient underwent proctectomy for megarectum. No failures occurred in patients with congenital or neurogenic disorders. CONCLUSIONS Malone antegrade continent enema is a reasonable option for the treatment of select patients with severe defecation disorders. Good functional patient self-reported outcome was achieved by 78 percent of patients. The social inconvenience of stoma leakage is avoided with appropriate surgical technique. Malone antegrade continent enema is one option that provides a less invasive surgical alternative than colectomy or ileostomy for severe defecation disorders.

Abstract
AIM: To investigate the therapeutic effectiveness of colonic exclusion and combined therapy for refractory constipation.
METHODS: Thirty-two patients with refractory constipation were randomly divided into treatment group (n = 14) and control group (n = 18). Fourteen patients in treatment group underwent colonic exclusion and end-to-side colorectal anastomosis. Eighteen patients in control group received subtotal colectomy and end-to-end colorectal anastomosis. The therapeutic effects of the operations were assessed by comparing the surgical time, incision length, volume of blood losses, hospital stay, recovery rate and complication incidence. All patients received long-term follow-up.
RESULTS: All operations were successful and patients recovered fully after the operations. In comparison of treatment group and control group, the surgical time (h), incision length (cm), volume of blood losses (mL), hospital stay (d) were 87 ± 16 min vs 194 ± 23 min (t = 9.85), 10.4 ± 0.5 cm vs 21.2 ± 1.8 cm (t = 14.26), 79.5 ± 31.3 mL vs 286.3 ± 49.2 mL (t = 17.24), and 11.8 ± 2.4 d vs 18.6 ± 2.6 d (t = 6.91), respectively (P < 0.001 for all). The recovery rate and complication incidence were 85.7% vs 88.9% (P = 0.14 > 0.05), 21.4% vs 33.3% (P = 0.73 > 0.05), respectively.
CONCLUSION: Colonic exclusion has better therapeutic efficacy on refractory constipation. It has many advantages such as shorter surgical time, smaller incision, fewer blood losses and shorter hospital stay.

Ripetti V, Caputo D, Greco S, Alloni R, Coppola R. Is total colectomy the right choice in intractable slow-transit constipation? Surgery 2006; 140:435-440. [PMID: 16934606 DOI: 10.1016/j.surg.2006.02.009] [Citation(s) in RCA: 34] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/09/2005] [Revised: 02/09/2006] [Accepted: 02/10/2006] [Indexed: 12/22/2022]
Abstract
BACKGROUND The aim of the study was to evaluate the functional results of surgical treatment for intractable slow-transit constipation and to establish that the importance of correct diagnosis and type of colon resection (total or segmental) is essential to achieve optimal outcome while minimizing side effects. METHODS Between 1995 and 2004, of the 450 patients presenting with chronic constipation, we further investigated 33 patients with a diagnosis of slow-transit constipation that had not improved with medical or rehabilitative treatment. Preoperative evaluation included a daily evacuation diary compiled using Wexner score, psychologic assessment, Medical Outcomes Study 36-item Short Form Health Survey (SF-36), radiologic investigation of colonic transit time, enema radiograph, colpo-cysto-defecography, anal manometry, and, in selected patients, colonoscopy and pudendal nerve terminal motor latency. In 15 cases, the cause of constipation was colonic slow-transit (with a mean Wexner score of 22), which was always associated with dolichocolon. The other 18 patients presented outlet obstruction, and, therefore, these results are not included in the present report. The 15 patients with slow-transit constipation were submitted to total laparoscopic colectomy (2), total open colectomy (6), and left laparoscopic hemicolectomy for left colonic slow-transit (7). RESULTS Mean follow-up was 38 months. All patients except 1 presented improvement in symptoms with daily evacuations (P < .01; mean Wexner score, 6). Furthermore, results of the SF-36 test showed an improvement in the perception of physical pain, and the emotional, psychologic, and general health spheres after surgical treatment. CONCLUSIONS Meticulous preoperative evaluation of intractable slow-transit constipation may discriminate between the different causes of chronic constipation and thus avoid the well-known "Iceberg syndrome," which is responsible for many treatment failures.

Abstract
Neural gastrointestinal electrical stimulation (NGES) induces sequential contractions and enhances emptying in acute canine gastric and colonic models. This study was set to determine (i) the effect of NGES in a chronic canine model of delayed colonic transit and (ii) possible mechanism of action. Four pairs of electrodes were implanted in the distal colon of nine mongrel dogs. Delayed colonic transit was induced by diphenoxylate/atropine and alosetron. Transit was fluoroscopically determined by the rate of evacuation of radiopaque markers, and was tested twice in each dog, in random order, on and off stimulation. Two stimulation sequences, separated by 1 min, were delivered twice a day via exteriorized electrodes. Colonic manometry during stimulation was performed before and after intravenous (i.v.) injection of 1 mg of atropine. Complete evacuation of all markers was significantly shortened by NGES, from 4 days to 2 days, interquartile range 3-4 days vs 2-3 days, respectively, P = 0.016. NGES induced strong sequential contractions that were significantly diminished by atropine: 190.0 +/- 14.0 mmHg vs 48.7 +/- 19.4 mmHg, respectively (P < 0.001). NGES induces strong sequential colonic contractions and significantly accelerates movement of content in a canine model of delayed colonic transit. The effect is atropine sensitive.

Abstract
Constipation, often related to diet, physical immobility, concurrent illness or multiple medication use, is common in older people. Despite potential for serious complications, constipation may often be overlooked. Management of constipation is a critical part of the care of older patients with chronic conditions. Risk assessment and appropriate nursing interventions and/or medication should mean that constipation can be minimized, preventing additional medication burden and reducing the risk of non-adherence. The relationship between quality of life and constipation has been assessed in numerous studies, showing that patients with constipation generally have an impaired quality of life compared with the general population, although studies in older patients are limited. In long-term survivors of colorectal or anal carcinoma, constipation is one of the factors that has the most negative impact on quality of life. Strategies for prevention and minimization of constipation have the potential to substantially improve quality of life for older people.

Abstract
OBJECTIVE This study reviews the functional outcome and satisfaction of patients after subtotal or total colectomy (STTC). METHODS A retrospective review of patients who underwent STTC between June 1999 and September 2003 was performed. A standardized questionnaire was formulated and phone interviews were conducted with these patients. RESULTS There were 50 patients who underwent STTC during this period. The most common indications were bleeding diverticular disease, patients with synchronous colorectal cancers or polyps and left-sided colonic obstruction. The presence of ischaemic heart disease and the development of perioperative acute coronary syndrome were found to be statistically significant predictors of 30 day mortality with P = 0.01 and 0.05, respectively. Phone interviews were successfully conducted in 33 patients. The patients interviewed were between 4 and 54 months postsurgery. Ninety-four percent reported that they were either happy or satisfied. Cleveland Clinic Incontinence Score (CCIS) revealed good or perfect continence in 94% of patients. Less than one-quarter of those interviewed had five or more bowel movements in a day while most had either two or three bowel movements a day. Patient satisfaction after STTC correlated strongly with the severity of CCIS and number of bowel movements a day (P < 0.01). Also, those with less than five bowel movements a day were more likely to report a better satisfaction (P < 0.01). CONCLUSION Subtotal or total colectomy is associated with a good functional outcome and most patients were satisfied with their bowel function on follow-up.

Abstract
Less than 10% of patients with slow-transit constipation require surgical management after failure of medical treatment. Preoperative clinical, psychological and colorectal routine investigations (ie colonic transit test, anorectal manometry and defecography) are mandatory in order to highly select the patients. To day, the surgical management of slow-transit constipation consists of subtotal colectomy with ileorectal anastomosis, eventually by laparoscopic approach. Although, surgical management improves slow-transit constipation in two thirds of the patients, small bowel obstruction, abdominal pain and constipation recurrence can occur in 25%, 50%, and 10% of the patients respectively.

Abstract
Patients suffering from primary constipation often show symptom improvement with increased intake of fiber. Bulk laxatives are a core component of treatment if dietary fiber is unsuccessful in alleviating symptoms. Although there are a number of commercial laxative preparations available, only polyethylene glycol (PEG), an osmotic laxative, should be used on a daily basis. For the elderly, saline laxatives may be used on a regular basis, provided there are no cardiac or renal comorbid contraindications. Tegaserod, a 5-HT(4) partial receptor agonist, is approved for the treatment of constipation in female patients. The appropriate role of biofeedback remains to be determined. Surgery should be reserved for patients with slow transit constipation refractory to medical therapy. Patients being considered for surgery should be evaluated at institutions with substantial expertise in the investigation and management of this population.
