RESUMO
BACKGROUND: The sampling reflex is necessary to begin defecation or flatulence. It consists of a simultaneous rectoanal inhibitory reflex (RAIR) mediated by relaxation of the internal anal sphincter and rectoanal excitatory reflex (RAER) mediated by contraction of the external anal sphincter. The aim of this study was to evaluate the sampling reflex in patients with functional defecation disorder (FDD). METHODS: A prospective cohort study was conducted on 58 obstructed defecation syndrome (ODS) patients with FDD. All 58 patients and 20 controls were evaluated with anorectal manometry to study the sampling reflex. Quantitative RAIR (total duration of reflex; maximal amplitude of relaxation; residual pressure at the lowest point of the RAIR) and RAER data (maximal amplitude of contraction; duration) were obtained. The straining test on manometry was considered positive for FDD if there was a muscle contraction/lack of relaxation or an insufficient pressure gradient for the passage of feces. Defecography was performed on all the patients with assessment of the anorectal angle and persistence or increase of puborectalis indentation. RESULTS: Fifty (86.2%) FDD patients had an altered sampling reflex, showing incomplete/short duration of RAIR and excessive contraction/duration of RAER. More specifically, there was a correlation between a positive straining test and a short total duration of RAIR (ρ 0.92) as well as with excessive duration of RAER (ρ 0.89). There was also a correlation between lack of muscle relaxation on defecography and short total duration of RAIR ((ρ 0.79) and between lack of muscle relaxation on defecography and excessive duration of RAER (ρ 0.83). Altered maximal amplitude relaxation had the highest sensitivity in detecting impairment of RAIR (87.9) while maximal amplitude contraction had the highest sensitivity in detecting impairment of RAER (89.6). High residual pressure at the lowest point of RAIR had the highest specificity in detecting impairment of RAIR (80.0) while RAER duration had the highest specificity in detecting impairment of RAER (77.7). CONCLUSION: The sampling reflex is impaired in patients with FDD. This finding provides an important insight into the pathogenesis of obstructed functional defecation.

Pelvic floor rehabilitation is frequently recommended for defecation disorders, in both constipation and fecal incontinence. However, the lack of patient selection, together with the variety of rehabilitation methods and protocols, often jeopardize the results of this approach, causing difficulty in evaluating outcomes and addressing proper management, and above all, in obtaining scientific evidence for the efficacy of these methods for specific indications. The authors represent different gastroenterological and surgical scientific societies in Italy, and their aim was to identify the indications and agree on treatment protocols for pelvic floor rehabilitation of patients with defecation disorders. This was achieved by means of a modified Delphi method, utilizing a working team (10 members) which developed the statements and a consensus group (15 members, different from the previous ones) which voted twice also suggesting modifications of the statements.

Rectal prolapse, rectal procidentia, "complete" prolapse or "third-degree" prolapse is the full-thickness prolapse of the rectal wall through the anal canal and has a significant impact on quality of life. The incidence of rectal prolapse has been estimated to be approximately 2.5 per 100,000 inhabitants with a clear predominance among elderly women. The aim of this consensus statement was to provide evidence-based data to allow an individualized and appropriate management and treatment of complete rectal prolapse. The strategy used to search for evidence was based on application of electronic sources such as MEDLINE, PubMed, Cochrane Review Library, CINAHL and EMBASE. The recommendations were defined and graded based on the current levels of evidence and in accordance with the criteria adopted by the American College of Gastroenterology's Chronic Constipation Task Force. Five evidence levels were defined. The recommendations were graded A, B, and C.

BACKGROUND: There is a certain number of subjects that consider themselves to be constipated (self diagnosed constipation; SDC). The Rome Criteria separate FC from IBS-C, but some SDC patients do not meet the Rome criteria (no Rome Constipation; NRC). Our aims were to evaluate the percentage of SDC subjects with a diagnosis of FC and IBS-C and to compare demographic and clinical features, symptoms, and quality of life in the different SDC groups (FC, IBS-C, NRC). METHODS: During a 2-month period, 934 patients and 980 accompanying persons (AP) were asked to complete a survey. The presence of FC or IBS-C was assessed. SDC subjects were invited to record the stool consistency (Bristol scale) and to fill in the Constipation Severity Index (CSI), obstructed defecation syndrome (ODS) and patient assessment of constipation-quality of life (PAC-QoL). The use of laxatives and enemas was evaluated. KEY RESULTS: The probability of the ROME III criteria being present was higher in SDC compared with no-SDC (OR 20.5). NRC was present in 13.5% of the SDC. In the patients' group the agreement between a diagnosis of Rome III and SDC was good (K 0.62), whereas in the AP it was moderate (K 0.56). NRC showed lower mean values of ODS, CSI and PAC-QoL, higher Bristol scale and a lower use of laxatives and enemas compared to IBS-C and FC. No differences were found between IBS-C and FC. CONCLUSIONS AND INFERENCES: The Rome III criteria identify subjects with a greater clinical impact, but separation of FC and IBS-C does not seem justified.

BACKGROUND: The motility of the defunctionalized colon, distal to transverse loop colostomy, has never been studied "in vivo." The aim of our study was to evaluate the influence of transverse loop colostomy on colonic motility. METHODS: Thirteen patients were examined before stoma closure by means of clinical evaluation and colonic manometry; we studied both the right and distal colon in both fasting and fed patients in order to detect motor activity. RESULTS: Quantitative and qualitative manometric analyses showed that the diverted colon had motor activity even if no regular colonic motor pattern was observed. The spreading of aboral propagated contractions (PCs) was sometimes recorded from the right colon to the distal colon. The response of the proximal and distal colon to a standard meal, when compared to fasting values, increased more than 40 and 35 %, respectively. Stool and gas ejections from the colostomy were never related to a particular type of colonic motility: Motor quiescence such as PCs was chaotically related to stool escape. CONCLUSIONS: In conclusion, motility of the defunctionalized colon is preserved in patients with transverse loop colostomy.

AIM: Passive postdefaecatory incontinence is poorly understood and yet is an important clinical problem. The aim of this study was to characterize the pathophysiology of postdefaecatory incontinence in patients affected by faecal soiling. METHOD: Seventy-two patients (30 women, age range 49-79 years; 42 men, age range, 53-75 years) affected by faecal passive incontinence with faecal soiling were included in the study. Two patient groups were identified: Group 1 comprised 42 patients with postdefaecatory incontinence and Group 2 had 30 patients without incontinence after bowel movements. After a preliminary clinical evaluation, including the Faecal Incontinence Severity Index (FISI) score and the obstructed defaecation syndrome (ODS) score, all patients of Groups 1 and 2 were studied by means of endoanal ultrasound and anorectal manometry. The results were compared with those from 20 healthy control subjects. RESULTS: A significantly higher ODS score was found in Group 1 (P < 0.001). Endoanal ultrasound revealed a significantly diffuse thinning of the internal anal sphincter (IAS) in Group 2 (P < 0.02) with a linear relationship between signs of IAS atrophy and the FISI score (ρs 0.78; P < 0.03). Anal resting pressure (Pmax and Pm ) was significantly lower in Group 2 (P < 0.04). The straining test was considered positive in 30 (71.4%) patients in Group 1, significantly greater than in Group 2 (P < 0.01). A significantly higher conscious rectal sensitivity threshold (CRST) was found in Group 1 patients (P < 0.01). CONCLUSION: The ODS score, a positive straining test and high CRST values suggest that postdefaecatory incontinence is secondary to impaired defaecation.

BACKGROUND: The aim of this study was to evaluate the results of rehabilitative treatment of incontinent patients with anal sphincter lesions in order to verify whether these lesions influence the outcome of rehabilitation. METHODS: Between January 2008 and June 2011, 48 patients [36 women, age range 51-77 years; 12 men, age range 57-70 years] affected by fecal incontinence were included in the study. After a preliminary clinical evaluation, including the Fecal Incontinence Severity Index (FISI) score, all patients were studied by means of endoanal ultrasound and anorectal manometry. Two patients groups were identified: Group 1 comprised 27 patients with sphincter lesions and Group 2 had 21 patients without sphincter lesions. All 48 underwent a multimodal rehabilitation program. At the end of the rehabilitation program, all patients were reassessed by means of clinical evaluation and anorectal manometry and their data were analyzed. RESULTS: Although we obtained an overall significantly lower FISI score in all patients after rehabilitation (p < 0.001) when compared with pre-treatment values, our study revealed that patients with sphincter lesions had a significantly worse post-rehabilitative FISI score (p < 0.003) when compared with those patients with intact anal sphincters and that there is a linear relationship between post-rehabilitative FISI scores and severity of sphincter lesions (ρ s 0.69). CONCLUSIONS: These data suggest that rehabilitation may be less effective in patients affected by sphincter defects.

AIM: The study was designed to evaluate the results of rehabilitative treatment in patients suffering from obstructed defaecation. METHOD: Between January 2008 and July 2010, 39 patients (37 women, age range 25-73 years; and two men, aged 57 and 67 years) affected by obstructed defaecation were included in the study. After a preliminary clinical evaluation, including the Obstructed Defaecation Syndrome (ODS) score, defaecography and anorectal manometry were performed. All 39 patients underwent rehabilitative treatment according to the 'multimodal rehabilitative programme' for obstructive defaecation. At the end of the programme, all 39 patients were reassessed by clinical evaluation and anorectal manometry. Postrehabilition ODS scores were used to categorize patients arbitrarily into three classes, as follows: class I, good (score ≤ 4); class II, fair (score > 4 to ≤ 8); and class III, poor (score > 8). RESULTS: After rehabilitation, there was significant improvement in the overall mean ODS score (P < 0.001). Thirty (76.9%) patients were included as class I (good results), of whom eight (20.5%) were symptom free. Five (12.8%) patients were considered class III. A significant postrehabilitative direct correlation was found between ODS score and pelvic surgery (ρ(s) = 0.54; P < 0.05). Significant differences were found between pre- and postrehabilitative manometric data from the straining test (P < 0.001), duration of maximal voluntary contraction (P < 0.001) and conscious rectal sensitivity threshold (P < 0.02). CONCLUSION: After rehabilitation, some patients become symptom free and many had an improved ODS score.

BACKGROUND: The aim of the study was to evaluate the clinical usefulness of anorectal manometry (AM) in patients affected by obstructed defecation (OD). METHODS: Between January 2007 and December 2010, 379 patients (287 women and 92 men) affected by OD were evaluated. After a preliminary clinical evaluation, defecography and AM were performed. The results were compared with those from 20 healthy control subjects. RESULTS: Overall anal resting pressure was not significantly different between patients and controls. Maximal voluntary contraction (MVC) data were significantly lower when compared with those of controls (P < 0.01). The straining test was considered positive in 143 patients. No significant difference was noted between patients and controls in maximal tolerated volume data. Patients had a significantly higher conscious rectal sensitivity threshold than controls (P < 0.02). CONCLUSIONS: A positive straining test, low MVC and impaired rectal sensation are the main abnormalities detected by AM in patients with OD.

BACKGROUND: Rehabilitation is the first therapeutic step of obstructed defecation, after failure of conservative therapy with high-fiber diet and laxatives. This study evaluates the usefulness of psyllium, a bulk-forming agent, when used during rehabilitation of obstructed defecation. METHODS: Between January 2008 and December 2010, 45 patients affected by obstructed defecation were included in the study. Two randomized groups were selected. Group 1 (21 women; age range 25-67 (mean, 51.8) years) continued to consume a high-fiber diet (approximately 30 g fiber per day) during rehabilitation. Group 2 (24 women; age range 46-71 (mean, 59.8) years) consumed only psyllium (3.6 g × 2/day; Psyllogel(®) Fibra, Nathura, Montecchio Emilia, Italy) during the rehabilitative cycle. After a preliminary clinical evaluation, including the obstructed defecation syndrome (ODS) score, patients underwent defecography and anorectal manometry as well as rehabilitative treatment according to the "multimodal rehabilitative program" for obstructive defecation. At the end of the program, patients were reassessed by clinical evaluation and anorectal manometry. Post-rehabilitative ODS scores were used for an arbitrary schedule of patients divided into three classes: Class I, good (score ≤ 4); Class II, fair (score > 4 to ≤ 8); Class III, poor (score > 8). RESULTS: The number of bowel movements per week did not increase significantly after rehabilitation. Both groups had a significantly better Bristol stool form scale score (Group 1: P < 0.034; Group 2: P < 0.02). The overall mean ODS score from Groups 1 and 2 showed significant improvement after treatment (P < 0.001). Twenty-eight patients (82.3%) were Class I (good results) without significant differences between groups. Nine women were symptom-free. Significant differences were found between pre-rehabilitative and post-rehabilitative manometric data from the straining test (P < 0.001) and duration of maximal voluntary contraction (Group 1: P < 0.004; Group 2: P < 0.02). A significant difference was found between the pre-rehabilitative and post-rehabilitative conscious rectal sensitivity threshold (CRST) in Group 2 women (P < 0.02). The Group 2 women who underwent volumetric rehabilitation (11 patients) had significantly lower post-rehabilitative CRST values than pre-rehabilitative values (P < 0.002); the length of volumetric rehabilitation was also significantly shorter in Group 2 patients (P < 0.04) than in Group 1 patients. CONCLUSIONS: After rehabilitation of obstructed defecation, some patients became symptom-free and many had an improved ODS score. Psyllium is helpful for volumetric rehabilitation: patients who consumed psyllium had lower post-rehabilitative CRST values than subjects were on high-fiber diet.

BACKGROUND: Patients suffering from severe fecal incontinence (FI) in whom surgical treatment has either failed or is inappropriate due to high operative risks and those who refuse to undergo surgery are condemned to living with their embarrassing symptoms, often responsible for progressive social isolation. ProTect is a new, relatively simple, medical device intended for selected patients suffering from severe FI. It consists of a pliable, silicone catheter with an inflatable balloon that seals the rectum at the anorectal junction, acting like an anal plug. The proximal part of the catheter incorporates two contacts that monitor the rectum for the presence of feces. The patient is alerted to an imminent bowel movement and, hence, a potential fecal accident, through a beeper. METHODS: A multicenter trial has been set up to assess the reliability of the device in preventing episodes of FI and to evaluate its impact on quality of life. Patients with significant FI (CCF>10) were prospectively entered into this 14-day study. Two quality of life questionnaires and a daily log of bowel activity and incontinent episodes were completed before and during the study. RESULTS: Currently, the study enrolled 17 patients and 11 patients (9 women, 2 men) with a mean age of 66 years (range, 46-85) completed the trial. In these 11 subjects, there was an overall significant improvement in the quality of life (p<0.05) and a significant reduction in incontinence scores (p<0.001) while using ProTect compared to baseline. CONCLUSIONS: The ProTect is a safe non-surgical device that is able to prevent episodes of FI. It is unique because it can be used according to a patient's needs without interfering with activities of daily living.

BACKGROUND: Available information on normal bowel habits was mainly gathered by means of telephone interviews or mailed questionnaires. AIMS: We undertook a prospective study to evaluate the defecatory habits in subjects perceiving themselves as normal concerning this function. SUBJECTS AND METHODS: A questionnaire (4-week diary with "yes-no" daily answers to six questions concerning bowel habits) was distributed to 204 subjects perceiving their defecation behaviour as normal. RESULTS: The completed questionnaire was returned by 140 subjects. No significant differences were found between sexes or age groups for any variable, even though straining at stool and feeling of incomplete and/or difficult evacuation showed a trend to increase with age. No subject had less than three bowel movements per week or more than three per day. The percentage of symptoms linked to an abnormal defecatory behaviour was well below 10%. Fifty-five percent of subjects reported at least one parameter of abnormal functioning; the most frequent was straining at stool and the rarer was the manual manoeuvres to help defecation. CONCLUSIONS: In normal subjects the prevalence of symptoms considered in Rome II criteria as part of an abnormal defecatory behaviour (in more than 25% of defecations) is well below 10%, manual manoeuvres are almost never used to help defecation, and the frequency of defecations is at least three per week.

Anterior resection of the rectum is a frequent surgical procedure. However, abnormal bowel habits following this procedure are frequently reported. The functional evaluation of these patients is usually limited to the anorectal area. By means of colonic manometry, we have evaluated a patient with frequent urge for defecation and increased bowel frequency following anterior resection of the rectum with straight coloanal anastomosis and almost normal anorectal function. Analysis of the tracing revealed a reduction of contractile segmental activity and much more high-amplitude propagated contractions than which occur in healthy subjects. These high-amplitude propagated contractions, representing the manometric equivalent of mass movements, were always in association with urge for defecation and, sometimes, with loose stools. High-amplitude simultaneous contractions were also observed. We feel that the surgical resection of a potential physiological brake may be responsible for these observations.

BACKGROUND: A consistent debate exists about the association between anal fissure and hypertonic anal canal. The aim of this study was to determine if the manometric findings in patients with chronic anal fissures varied according to the topography of the fissure. PATIENTS AND METHODS: Seventy-three outpatients (52 men, 71%) with chronic anal fissures and nine healthy volunteers (5 men, 55%) were examined. Patients were classified according to the topography of the anal fissures: posterior midline (group A), anterior midline (group B), and lateral position (group C). We use computerized anorectal manometry to evaluate anal resting pressure, maximal voluntary contraction, recto-anal inhibitory reflex, rectal sensations and rectum compliance. RESULTS: In Group A, the mean pressure was higher than that of controls (p<0.05), and the resting pressure 2 cm from anal verge was higher than that of other groups and controls (p<0.05). Normotonic anal canal was found in 49.1% of patients in group A, in 66% of those in group B and in 57.1% of those in group C. Four elderly patients (7%) of group A had a hypotonic anal canal. No differences were found regarding maximal voluntary contraction, recto-anal inhibitory reflex, rectal sensations and rectum compliance between patients and controls. CONCLUSIONS: Patients with chronic anal fissures may have several anal pressure profiles. The anal canal is often normotonic. Fissures with hypertonic or normo-hypotonic anal canal need different therapies.

BACKGROUND: Sphincter exercises and biofeedback therapy have been used to treat faecal incontinence but results have been unpredictable and standards of treatment have not yet been established. The aim of this study was to retrospectively evaluate the effects of a new multimodal rehabilitation model on faecal incontinence. METHODS: All of the rehabilitative procedures are guided by manometric data. Primary study outcome criteria were the determination of changes or deterioration in incontinence, failure to achieve full continence and/or presence of faecal urgency. The clinical outcome was designed according to the Jorge-Wexner incontinence score. RESULTS: Between 1997 and 2001, one hundred forty-nine incontinent patients (85 F and 64 M; age range, 41-73 years; mean age, 60.6 years) underwent multimodal rehabilitation at our outpatient unit. The overall mean incontinence score had significantly improved after treatment ( p<0.001), and 58 patients (38.9%) were symptom free. No patient reported any deterioration in incontinence. Faecal urgency persisted in 23 patients (15.4%). CONCLUSION: In conclusion, multimodal rehabilitation, using manometric study, can modify the incontinence score.

BACKGROUND: Myotonic dystrophy is often associated with digestive symptoms that can precede the clinical appearance of skeletal muscle involvement. Although motility disorders may be observed in these patients at any level of the gastrointestinal tract, upper gastrointestinal symptoms have up to now usually been considered to be due to oesophageal rather than gastric dysmotility. AIMS: To evaluate: a) gastric emptying in myotonic dystrophic patients without dyspeptic symptoms, and b) relationship between gastric emptying and severity and duration of the disease. PATIENTS AND METHODS: Gastric emptying was evaluated in 11 non-dyspeptic dystrophic patients and in 22 healthy volunteers by means of computerised ultrasound scan, assessing the variation in the antral area over time after ingestion of a meal. RESULTS: The final emptying time was higher in patients than in healthy volunteers (373' +/- 35' vs 270' +/- 47'; p < 0.001). Basal and maximal post-prandial antral areas were similar in the two groups. There was a significant correlation between gastric emptying and the duration of the disease (rs = 0.62; p = 0.04). No relationship was found between gastric emptying and severity of the disease. CONCLUSIONS: Gastric emptying may be abnormally delayed in myotonic dystrophy patients, even in absence of dyspeptic symptoms. This delay is correlated with duration but not with severity of the disease. However there is no difference in either basal or maximal postprandial antral areas between myotonic dystrophy patients and healthy volunteers.

This technical note presents a variation of the stapled mucosal prolapsectomy for haemorrhoidal prolapse using the Lone Star Retractor. Our experience highlights the simplicity and usefulness of the technique which is based on the complete eversion of the prolapse carried out by the Lone Star Retractor, without using any kind of proctoscope and without stretching the anal sphincters. Postoperatively, rectal bleeding occurred in 4.7% of 127 cases, 9.8% of the patients complained of faecal urgency and only 3.9% had severe anal pain. None had faecal incontinence. This method simplifies the making of the purse-string suture as well as the use of the suturing device and achieves satisfactory clinical results.

OBJECTIVE: To find out whether tumour DNA content correlates with allelic loss of p53 and other pathological features in primary colorectal carcinomas. DESIGN: Ongoing prospective study. SETTING: University hospital, Italy. SUBJECTS: 128 patients who had undergone radical resections for colorectal carcinoma. INTERVENTIONS: Flow cytometric measurement of tumour DNA content and detection of allelic loss on the short arm of chromosome 17 by Southern blot (restriction fragment length polymorphism) analysis in fresh tumour specimens. MAIN OUTCOME MEASURES: Correlation between DNA ploidy and deletion of p53, as well as between these two genetic events and clinicopathological variables. RESULTS: Interpretable DNA histograms were obtained for 122 tumour specimens. Forty-three tumours (35%) were diploid and 79 (65%) aneuploid. The diploid tumours were significantly more common in the proximal colon (from the caecum to the splenic flexure) than in the distal colon (from the descending colon to the rectum) (p = 0.002). The allelic state on the short arm of chromosome 17 was evaluated in 80 heterozygous patients. Forty-four tumour specimens (55%) showed deletion of 17p. Allelic loss of p53 was significantly more common in the distal and rectal tumours than in the proximal ones (p < 0.0001). Aneuploidy was more common among those tumours which had shown deletion of p53 than in those that had not (p = 0.0008). CONCLUSIONS: DNA aneuploidy was significantly associated with the deletion of the p53 gene. This suggests that the functional loss of p53 may favour the growth and establishment of an aneuploid cell population within tumours. Tumours of the proximal and distal colon differ in their genetic nature.
