[PMID: 35194918 PMCID: PMC9541108 DOI: 10.1111/codi.16101] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/29/2021] [Revised: 01/30/2022] [Accepted: 02/14/2022] [Indexed: 12/13/2022]
Abstract
AIM Our hypothesis is that there may be a neural pathway with sensory afferent neurons in the anal canal that leads to rectal contraction to assist defaecation. We aimed to compare rectal motility between healthy participants with or without anal anaesthesia. METHOD This prospective intervention study consisted of two test sessions: a baseline session followed by an identical second session. During each session we performed the anal electrosensitivity test, the rectoanal inhibitory reflex test and rapid phasic barostat distensions. Prior to the second session, participants were randomly assigned to receive either a local anal anaesthetic or a placebo. RESULTS We included 23 healthy participants aged 21.1 ± 0.5 years, 13 of whom received an anal anaesthetic and 10 a placebo. All participants showed a transient rectal contraction during the first test session, which decreased significantly after anal anaesthesia (18.6 ml vs. 4.9 ml, p = 0.019). The maximum rectal contraction was comparable to the baseline results in the placebo group. Furthermore, the electrosensitivity at the highest centimetre of the anal canal correlated with the maximum rectal contraction (r = -0.452, p = 0.045). CONCLUSION All healthy study participants display an involuntary, reproducible rectal reflex contraction that appears to be innervated by afferent nerves in the proximal anal canal. The rectal reflex contraction appears to play a role in defaecation and we therefore refer to this phenomenon as the anorectal defaecation reflex. Knowledge of the anorectal defaecation reflex may have consequences for the diagnostics and treatment of constipation.

Abstract
BACKGROUND/AIMS Anorectal diseases, including fecal incontinence, are prevalent and have an enormous impact on the quality of life. Therefore, investigating their etiological factors may help to reduce the incidence and/or the severity of the underlying diseases. MATERIALS AND METHODS Referral complaints (constipation, strained defecation, and incontinence) and medical and anorectal manometry records of 883 (562 female/321 male, ages 45.17±1.00 and 48.41±0.63 years, respectively) patients were evaluated retrospectively. Maximal resting pressure (MRP) and maximal squeeze pressure (MSP) measured by stationary pull-through technique, volume of rectoanal inhibitory reflex, and sensory threshold to rectal balloon distention (ST) were obtained by water perfusion system. Data were compared according to referral complaints, age, gender, parity, and underlying diseases. RESULTS Incontinence was the most frequent referral complaint in 61.2% of females and 67.6% of males. MRP and MSP were significantly lower in incontinent females than in the other groups. In incontinent males, MSP was lower than the strained defecation group, and ST was higher than the constipation group. Age was negatively correlated with MRP for both of the genders and in all groups. Obstetric trauma (85%) and number of parity (3.40±2.59) were significantly higher in incontinent females. Moreover, the most prevalent underlying disease was diabetes in incontinent females (13.7%) and neurological diseases, including traumas, in incontinent males (41.5%). CONCLUSION Increasing awareness of labor safety, controlling diabetes mellitus, and preventing obstetric traumas may reduce the prevalence of fecal incontinence.

Abstract
Faecal incontinence, defined as the involuntary loss of solid or liquid stool, is a common problem affecting 0.8-8.3% of the adult population. Individuals suffering from faecal incontinence often live a restricted life with reduced quality of life. The present paper is a clinically oriented review of the pathophysiology, evaluation and treatment of faecal incontinence. First-line therapy should be conservative and usually include dietary adjustments, fibre supplement, constipating agents or mini enemas. Biofeedback therapy to improve external anal sphincter function can be offered but the evidence for long-term effect is poor. There is good evidence that colonic irrigation can reduce symptoms and improve quality of life, especially in patients with neurogenic faecal incontinence. Surgical interventions should only be considered if conservative measures fail. Sacral nerve stimulation is a minimally invasive procedure with high rate of success. Advanced surgical procedures should be restricted to highly selected patients and only performed at specialist centres. A stoma should be considered if other treatment modalities fail.

Abstract
BACKGROUND Conscious external anal sphincter contraction is mediated by the pudendal nerve. Pudendal neuropathy is, therefore, believed to result in fecal incontinence. Until urge sensation is experienced, fecal continence is maintained by unconscious external anal sphincter contraction, which is regulated by the anal-external sphincter continence reflex. The innervation of unconscious contraction is yet unknown. OBJECTIVE We aimed to determine whether unconscious contraction is mediated by the pudendal nerve and whether age influences unconscious contraction. DESIGN This was a retrospective comparative study. SETTINGS The study was conducted in a tertiary care center. PATIENTS Seventy adult patients experiencing defecation problems who underwent anorectal function tests were included in this study. MAIN OUTCOME MEASURES Conscious and unconscious contractions were compared between patients with and without pudendal neuropathy. Conscious contraction was defined by maximum anal sphincter contractility, unconscious contraction by pressure in the anal canal at maximum tolerable or retainable sensation during the balloon retention test. RESULTS Unconscious contraction did not differ significantly between patients with pudendal neuropathy and non-pudendal neuropathy patients, whereas conscious contraction was significantly lower in patients with pudendal neuropathy. Multiple linear regression analyses demonstrated that unconscious contraction, in contrast to conscious contraction, was not predicted significantly by age and anal electrosensitivity at 2 cm, which represents pudendal neuropathy. Patients with pudendal neuropathy were significantly older than patients with nonpudendal neuropathy. LIMITATIONS The pudendal nerve motor latency and EMG tests were not performed. CONCLUSIONS The pudendal nerve does not mediate unconscious external anal sphincter contraction. Pudendal neuropathy alone, therefore, results in urge incontinence rather than in complete fecal incontinence. Unconscious contraction appears not to be influenced by age. Therefore, most of the elderly patients experience urge incontinence rather than complete fecal incontinence.

Abstract
BACKGROUND None of the current theories on fecal incontinence can explain fecal continence adequately. OBJECTIVE This study aims to evaluate the mechanism controlling fecal continence. DESIGN Anal electrosensitivity, anorectal pressures, and rectal pressure volumetry tests were performed in 17 controls before and after superficial local anal anesthesia and in 6 controls before and after spinal anesthesia. The same tests were performed in 1 patient before and after injected local anal anesthesia and in 3 patients with spinal cord lesions at levels Th3 to L3. RESULTS After superficial local anal anesthesia, anal electrosensitivity decreased, but basal anal pressure remained unaltered. Squeeze pressure decreased and rectal filling sensation levels remained. Local anesthesia reduced anal pressure recorded in the distal anal canal during progressive rectal filling. This was also the case, albeit more explicit, after the local anal anesthetic was injected. After spinal anesthesia, the anal canal became insensitive to electric stimulation, but basal and squeeze pressure values decreased substantially, and the increase in anal pressure during the balloon-retaining test disappeared completely. In the patients with spinal cord lesions, the external sphincter could not be squeezed on command, but during the balloon-retaining test, the anal sphincter did squeeze autonomously at more than 300 mmHg. LIMITATIONS These were partially experimental measurements. The relevance of the found model in the daily clinical practice will have to be studied in a following study. CONCLUSIONS Our results support the hypothesis that the component of fecal continence mediated by contraction of the external sphincter depends on a anal external sphincter continence reflex without involving the brain. Presumably, the afferent receptors of this reflex are contact receptors located superficially in the mucosa or submucosa of the distal anal canal. A nonfunctioning anal external sphincter continence reflex would, therefore, result in fecal incontinence (see Video, Supplemental Digital Content 1, http://links.lww.com/DCR/A116).

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-operative interventions (for example pelvic floor muscle training, biofeedback, drugs) and surgical procedures. A surgical procedure may be aimed at correcting an obvious mechanical defect, or augmenting a functionally deficient but structurally intact sphincter complex. OBJECTIVES To assess the effects of surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aim was firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH METHODS Electronic searches of the Cochrane Incontinence Group Specialised Register (searched 6 March 2013), the Cochrane Colorectal Cancer Group Specialised Register (searched 6 March 2013), CENTRAL (2013, issue 1) and EMBASE (1 January 1998 to 6 March 2013) were undertaken. The British Journal of Surgery (1 January 1995 to 6 March 2013), Colorectal Diseases (1 January 2000 to 6 March 2013) and the Diseases of the Colon and Rectum (1 January 1995 to 6 March 2013) were specifically handsearched. The proceedings of the Association of Coloproctology of Great Britain and Ireland annual meetings held from 1999 to 2012 were perused. Reference lists of all relevant articles were searched for further trials. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other than surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Three review authors independently selected studies from the literature, assessed the methodological quality of eligible trials and extracted data. The three primary outcome measures were change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Nine trials were included with a total sample size of 264 participants. Two trials included a group managed non-surgically. One trial compared levatorplasty with anal plug electrostimulation and one compared an artificial bowel sphincter with best supportive care. The artificial bowel sphincter resulted in significant improvements in at least one primary outcome but the numbers were small. The other trial showed no difference in the primary outcome measures.Seven trials compared different surgical interventions. These included anterior levatorplasty versus postanal repair, anterior levatorplasty versus total pelvic floor repair, total pelvic floor versus postanal repair, end to end versus overlap sphincter repair, overlap repair with or without a defunctioning stoma or with or without biofeedback, and total pelvic floor repair versus repair plus internal sphincter plication and neosphincter formation versus total pelvic floor repair. Sacral nerve stimulation and injectables are considered in separate Cochrane reviews. Only one comparison had more than one trial (total pelvic floor versus postanal repair, 44 participants) and no trial showed any difference in primary outcome measures. AUTHORS' CONCLUSIONS The review is striking for the lack of high quality randomised controlled trials on faecal incontinence surgery that have been carried out in the last 10 years. Those trials that have been carried out have focused on sacral neuromodulation and injectable bulking agents, both reported in separate reviews. The continued small number of relevant trials identified together with their small sample sizes and other methodological weaknesses limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are still needed. However, it should be recognised that the optimal treatment regime may be a complex combination of various surgical and non-surgical therapies.

Abstract
AIM Anorectal function was assessed in patients with and without faecal incontinence (FI) . Risk factors predictive for FI were determined. METHOD Between 2003 and 2009, all consecutive patients referred were assessed by questionnaire, anorectal manometry and anal endosonography. Predictive factors were identified and used to develop a statistical model to predict FI. RESULTS Of 600 patients (519 women), 285 (48%) were faecally incontinent. In comparison with continent women, incontinent women (mean Vaizey score 15.4), were older, had more liquid stools, more deliveries, more urinary incontinence, lower anal pressures, shorter sphincter length, smaller rectal capacity and more sphincter defects. Incontinent men (mean Vaizey score 15.3) were older and had lower anal pressures. Incontinent and continent patients showed an overlap in test results. Predictors in women were age, stool consistency, anal pressures, rectal capacity, and internal and external sphincter defects. The area under the ROC-curve was 0.84 (P < 0.001; 95% confidence interval, 0.80-0.87). Using a cut off point of 0.4, FI was predicted with sensitivity, specificity, positive and negative predictive values of 86%, 68%, 74% and 82%, respectively. The model was studied in five women with a temporary stoma and was accurate in predicting FI after stoma closure. CONCLUSION Incontinent patients have lower pressures, smaller rectal capacity and more sphincter defects than controls, but show a large overlap. Our model shows a relatively high sensitivity and negative predictive value for predicting FI in women. The model seems promising in the patients studied with a temporary stoma.

Abstract
PURPOSE The purpose of this study was to assess both the short- and long-term functional outcomes of stapled transanal rectal resection (STARR) in ODS patients. PATIENTS AND METHODS We performed a retrospective review of data that were collected from January 2005 to October 2008. Between January 2005 to June 2006, 58 patients who underwent STARR were enrolled in this study. Follow-up was scheduled for 3 months and 1 year after surgery with the Cleveland Clinic Florida (CCF) constipation score and satisfaction grade. To evaluate the long-term functional outcome, we interviewed the patients by telephone using questionnaires for the CCF score and satisfaction grade on October 2008. RESULTS The median follow-up period was 34 months (range, 27-46 months). The mean age and sex ratio were 54 years (range, 19-85 years) and 8:50 (M/F). The mean CCF constipation scores were 17.6 before the surgery, 9.5 at 3 months, 9.6 at 12 months, and 10.3 at the time of the latest interview. The satisfaction grade, which was rated as excellent and good by 63.4% of the patients at the time of the latest interview, was worse than that at 3 months (37.8%). Among the cases of the excellent group (19 cases) at postoperative 3 months, 13 cases (68.4%) were classified as excellent or good at the time of the latest interview. CONCLUSION The STARR is a safe and effective surgical procedure for restoring the anatomy and function in ODS patients. Strict selection of patients is needed in enhancing and maintaining the patients' satisfaction after the procedure.

Abstract
AIMS Many procedures have been described for the treatment of rectal internal mucosal prolapse (RMP), but the therapeutic effect is questionable. This work is to evaluate clinical and functional outcome of a modified Delorme's operation-trans-anal purse-string sutures for rectal mucosa and submucosa (TAS) for the treatment of RMP. METHODS The clinical data of 58 patients with rectal mucosal prolapse treated with rectal mucosa and submucosal tissue (TAS) between June 2004 and June 2008 were analyzed retrospectively. RESULTS No patient died. Satisfaction with surgery was high in 48 cases (82.8%), moderate in seven (12.1%), and low in three (5.17%). Prolapse relapse rate was 5.17%. Anal tenesmus and urge to defecate resolved in 52 (89.7%) patients. Constipation improved in 25 of 28 (89.3%) previously constipated patients. No surgery-associated constipation occurred. The mean operative time was 31 (range 22-46) min. Mean hospital stay was 3 days (range 2-6). Mean patient follow-up was 32 months (range 12-60). CONCLUSIONS From our data, TAS for the treatment of RMP showed encouraging results with little complications and an acceptable relapse rate. This economical procedure induces only mild trauma and is easy to perform, making it worthy of further practice and investigation.

Abstract
Anorectal disorders like haemorrhoids, rectal prolapse, anal fissures, peri-anal fistulae and sexually transmitted diseases are bothersome benign conditions that warrant special attention. They, however, can all be diagnosed by inspection or proctoscopy (sexually transmitted proctitis). Constipation can play an underlying role in haemorrhoids, rectal prolapse and anal fissures, and it is important to treat these conditions in order to avoid recurrences. Haemorrhoids and anal fissures are generally treated conservatively and surgery is seldom required. Rectal prolapse and cryptoglandular peri-anal fistulae are treated surgically. In a recurrent peri-anal fistula, the fistular tract needs to be visualised with anal ultrasound or magnetic resonance imaging (MRI). There are different techniques available for this evaluation, and care must be taken not to damage the anal sphincter. Peri-anal fistulae in Crohn's disease are treated conservatively and surgery is only required in cases with abscesses. Sexually transmitted proctitis needs to be adequately recognised and treated according to the infectious agent.

Abstract
Rectal prolapse is best diagnosed by physical examination and by having the patient strain as if to defecate; a laparoscopic rectopexy is the preferred treatment approach. Intussusception is more an epiphenomena than a defecatory disorder and should be managed conservatively. Solitary rectal ulcer syndrome is a consequence of chronic straining and therapy should be aimed at restoring a normal bowel habit with behavioral approaches including biofeedback therapy. Rectocele correction may be considered if it can be definitively established that it is a cause of defecation disorder and only after conservative measures have failed. An enterocele should only be operated when pain and heaviness are predominant symptoms and it is refractory to conservative therapy.

Abstract
With advances in diagnostic technology, it is now accepted that in the field of functional bowel disorders, symptom-based assessment is unsatisfactory as the sole means of directing therapy. A robust taxonomy based on underlying pathophysiology has been suggested, highlighting a crucial role for physiologic testing in clinical practice. A wide number of complementary investigations currently exist for the assessment of anorectal structure and function, some of which have a clinical impact in patients with functional disorders of evacuation and continence by markedly improving diagnostic yield and altering management. The techniques, limitations, measurements, and clinical use of manometric, sensorimotor, and neurophysiologic tests of anorectal function are presented.

Abstract
Neurophysiological tests of anorectal function can provide useful information regarding the integrity of neuronal innervation, as well as neuromuscular function. This information can give insights regarding the pathophysiological mechanisms that lead to several disorders of anorectal function, particularly fecal incontinence, pelvic floor disorders and dyssynergic defecation. Currently, several tests are available for the neurophysiological evaluation of anorectal function. These tests are mostly performed on patients referred to tertiary care centers, either following negative evaluations or when there is lack of response to conventional therapy. Judicious use of these tests can reveal significant and new understanding of the underlying mechanism(s) that could pave the way for better management of these disorders. In addition, these techniques are complementary to other modalities of investigation, such as pelvic floor imaging. The most commonly performed neurophysiological tests, along with their indications and clinical utility are discussed. Several novel techniques are evolving that may reveal new information on brain-gut interactions.

Abstract
BACKGROUND Intersphincteric resection (ISR) is the ultimate sphincter-preserving operation for very low rectal cancer. The aim of this study was to assess defaecatory function after ISR in relation to the degree of resection of the internal anal sphincter. METHODS Between 2001 and 2003, 35 consecutive patients with low rectal cancer had curative ISR, categorized as total, subtotal or partial resection of the internal anal sphincter. Defaecatory function was assessed in terms of frequency of bowel movements and continence. Sphincter function was evaluated by manometric study and anorectal sensation testing before surgery and 3, 6 and 12 months afterwards. RESULTS Defaecatory function was satisfactory after ISR; 34 of 35 patients were grossly continent. The maximum resting anal canal pressure fell after all three procedures. Patients who had total ISR had reduced anal canal sensation at 3 months, but this had improved by 12 months after surgery. CONCLUSION These functional results suggest that ISR should be considered as an alternative to abdominoperineal resection for low rectal cancer. However, as the outcome for continence is worse after total ISR than subtotal or partial ISR, the indication for total ISR should strictly take into account the preoperative sphincter function.

Abstract
OBJECTIVE To derive a range of normal values for anal sphincter resting and squeeze pressure, and anorectal sensation in healthy women without anorectal disease before and after their first childbirth. METHOD Nulliparous women undergoing anal physiology testing in the third trimester of pregnancy and 12 weeks after delivery. All were asked to undergo anal manometry and anorectal electrosensation testing. Maximum resting pressure, maximum squeeze pressure and anal thresholds to electrical current were assessed at 1 cm intervals down the anal canal. Rectal electrosensitivity thresholds were assessed 10 cm from the anal verge. RESULTS A total of 286 women attended for antenatal investigations and 161 (56%) returned postpartum. The anal canal length was 3.9 +/- 0.6 cm antenatally and 3.9 +/- 0.6 cm postnatally. During pregnancy the 95% normal range for anal resting and squeeze pressures, anal and rectal sensation were 29-90 mmHg, 50-163 mmHg, 2-31 mA and 3-33 mA respectively. Post delivery the 95% normal ranges were 27-98 mmHg, 43-156, 2-12 mA and 0.1-34 mA respectively. Both antenatally and postnatally the manometry and sensitivity values were similar in women with and without bowel symptoms. CONCLUSION This study is the largest series of normative data for anal manometry, and anorectal sensation in women before and after their first delivery. The antenatal values can serve to represent ranges for nulliparous women and the postnatal values ranges in primiparous women.

Abstract
Rectal hyposensitivity (RH) is commonly found in patients with intractable constipation, faecal incontinence or both. Anal sensation may also be blunted in these conditions. We aimed to determine whether RH is associated with anal hyposensitivity, which may reflect a combined viscero-somatic neuropathy. One hundred and fifty-eight female patients with chronic constipation underwent physiological investigation including rectal sensation to volumetric balloon distension, and distal anal mucosal sensation to electrostimulation. Data were also obtained from 32 healthy female volunteers. Anal mucosal electrosensory thresholds were significantly higher in patients compared with volunteers (median: 2.4 mA, range: 0.4-19.6 vs 1.1 mA, range: 0.1-4.2, respectively), although the patient group was older (P < 0.0001), but there was no difference (P = 0.572) in the incidence of blunted anal sensation between those with normal rectal sensation (n = 113, 20% abnormal) and RH (n = 45, 24% abnormal). Irrespective of rectal sensory function, there was a strong association between symptom duration (P = 0.012) and anal hyposensitivity. One-fifth of constipated female patients had evidence of diminished anal sensation. However, the presence of RH was not associated with an increased frequency of anal hyposensitivity, thereby suggesting that different aetiopathogenic mechanisms underlie the development of anal and rectal hyposensitivity. Further studies in carefully selected, homogenous patient populations are necessary to elucidate these mechanisms.

Abstract
BACKGROUND Anal inspection and digital rectal examination are routinely performed in fecal incontinent patients but it is not clear to what extent they contribute to the diagnostic work-up. We examined if and how findings of anal inspection and rectal examination are associated with anorectal function tests and endoanal ultrasonography. METHODS A cohort of fecal incontinent patients (n=312, 90% females; mean age 59) prospectively underwent anal inspection and rectal examination. Findings were compared with results of anorectal function tests and endoanal ultrasonography. RESULTS Absent, decreased and normal resting and squeeze pressures at rectal examination correlated to some extent with mean (+/-SD) manometric findings: mean resting pressure 41.3 (+/-20), 43.8 (+/-20) and 61.6 (+/-23) Hg (p<0.001); incremental squeeze pressure 20.6 (+/-20), 38.4 (+/-31) and 62.4 (+/-34) Hg (p<0.001). External anal sphincter defects at rectal examination were confirmed with endoanal ultrasonography for defects <90 degrees in 36% (37/103); for defects between 90-150 degrees in 61% (20/33); for defects between 150-270 degrees in 100% (6/6). Patients with anal scar tissue at anal inspection had lower incremental squeeze pressures (p=0.04); patients with a gaping anus had lower resting pressures (p=0.013) at anorectal manometry. All other findings were not related to any anorectal function test or endoanal ultrasonography. CONCLUSIONS Anal inspection and digital rectal examination can give accurate information about internal and external anal sphincter function but are inaccurate for determining external anal sphincter defects <90 degrees. Therefore, a sufficient diagnostic work-up should comprise at least rectal examination, anal inspection and endoanal ultrasonography.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-surgical interventions (e.g. pelvic floor muscle training, biofeedback, drugs, sacral nerve stimulation) and surgical procedures. A surgical procedure may be aimed at correcting an obvious mechanical defect, or augmenting a functionally deficient but structurally intact sphincter complex or replace an absent/non-functioning sphincter. OBJECTIVES To assess the effects of surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aim was firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group Specialised Trials Register (31 January 2006), the Cochrane Colorectal Cancer Group trials register (31 January 2006), the Cochrane Central Register of Controlled Trials (2006, Issue 1), PubMed (1 January 1950 to 31 January 2006) and EMBASE (1 January 1998 to 31 January 2006) were undertaken. The British Journal of Surgery (January 1995 to May 2006) Colorectal Diseases (January 2000-May 2006) and the Diseases of the Colon and Rectum (January 1995 to May 2006) were specifically handsearched. The proceedings of the Association of Coloproctology meeting held from 1999 to 2006 were perused. Reference lists of all relevant articles were searched for further trials. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other than surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature searches, assessed the methodological quality of eligible trials and extracted data. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Nine trials were included with a total sample size of 264 participants. Two trials included a group managed non-surgically. One trial compared levatorplasty with anal plug stimulation, one compared artificial bowel sphincter with best supportive care; numbers were small in both trials. The artificial bowel sphincter insertion was followed by significant improvements in at least one primary outcome but with high rates of significant morbidity. Seven studies compared different surgical interventions. These included anterior levatorplasty versus postanal repair, anterior levatorplasty versus total pelvic floor repair, total pelvic floor versus postanal repair, end to end versus overlap sphincter repair, overlap repair with or without a defunctioning stoma or with or without biofeedback, total pelvic floor repair versus repair plus internal sphincter plication and neosphincter formation versus total pelvic floor repair. Only one comparison had more that one trial (total pelvic floor versus postanal repair-44 participants) and no comparison showed any statistically significant difference in primary outcome measures, with wide confidence intervals. AUTHORS' CONCLUSIONS Despite more studies being included in this update, the continued small number of relevant trials identified together with their small sample sizes and other methodological weaknesses continue to limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are still needed. However, it should be recognised that the optimal treatment regime may be a complex combination of various surgical and non-surgical therapies.

Abstract
INTRODUCTION To clarify the significance of anal canal sensitivity contribution to soiling in patients after ileal J pouch-anal anastomosis (IPAA) for ulcerative colitis (UC), we studied the sensory function of the anal canal. METHODS Forty patients with UC who had undergone IPAA with ileostomy closure at least 60 to 132 months (mean 103.6 months) previously, and who had no preoperative or postoperative complications were recruited. They were divided into two groups: group A [n = 26; patients without soiling (16 males, 10 females; ages 15-49 years, mean 36.6 years)] and group B [n = 14; patients with soiling (10 men, 4 women; ages 24-56 years, mean 40.9 years)] compared with group C [n = 28; control subjects (18 men, 10 women; aged 19-49 years, mean 38.5 years)]. Patients with soiling were also divided into three groups (B1, rare soiling; B2, occasional soiling; B3, frequent soiling). The anal canal sensitivity threshold was measured using an anal canal electrosensitivity test (ACEST). The measurement point of anal canal was divided into three parts: lower part [1 cm below the dentate line (DL), middle part (just on the DL), and upper part (1 cm above the DL]. A small electric current from a constant-current generator was passed between the electrodes until the patient felt a sensation often described as tingling or pulsing. The threshold of sensitivity was assessed in the upper, middle, and lower parts of the anal canal. RESULTS In patients of group C, recording at the middle part of the anal canal showed the best results. The anal canal sensitivity threshold of group B was significantly higher than those of groups A and C at the upper and middle parts (P < 0.0001, respectively). There were no significant differences at the lower part among groups. The anal canal sensitivity threshold of subgroup B3 was significantly higher than those of groups B1 or B2 at both the upper part (P = 0.0002, P = 0.0038, respectively) and middle part (P = 0.0001, P = 0.0480, respectively). There were no significant differences at the lower part among groups. CONCLUSIONS The ACEST shows significantly lower sensitivity in the proximal and middle anal canal in IPAA patients with soiling.

Abstract
OBJECTIVES Fecal incontinence is classified into various types: passive, urge, and combined. Its clinical presentation is thought to be related to the underlying physiological or anatomical abnormality. The aim of the present study was to evaluate the associations between the frequency of clinical symptoms and anatomic and functional characteristics of the anorectum of patients with severe fecal incontinence. METHODS Associations were explored in a consecutive series of 162 patients (91% women, mean age 59 [SD +/- 12] yr) with a mean Vaizey incontinence score of 18 (SD +/- 3). RESULTS Urge incontinence was reported as "daily" by 55%, "often" by 27%, and "sometimes" by 7% of all patients. No significant associations were observed between the frequency of urge incontinence and either manometric data, anal mucosal sensitivity testing, or defects of internal anal sphincter (IAS) or external anal sphincter (EAS). A significant relation was observed between the frequency of urge incontinence and maximal tolerable volume (P= 0.03) and atrophy of the EAS (P= 0.05). Passive incontinence was reported as "daily" by 14%, "often" by 30%, and "sometimes" by 14% of all patients. Resting and maximal squeeze pressure were both associated (P < 0.001) with the frequency of passive incontinence. No relationship could be detected between clinical presentation and rectal sensation, anal mucosal sensitivity, defects, or atrophy of IAS or EAS. CONCLUSION Most patients reported combined incontinence (59%) and underlying pathophysiologic abnormalities were identified. The hypothesized associations between urge and passive incontinence and functional and anatomical impairment of the anorectum are less clear-cut than previously assumed. Patients presenting with fecal incontinence should undergo physiologic investigation.

Abstract
BACKGROUND Physiotherapy is a common treatment option in patients with fecal incontinence. Although physiotherapy may result in relief of symptoms, to what extent improvement is associated with changes in anorectal function is still unclear. AIM The aim of the present study was to investigate prospectively how anorectal function changes with physiotherapy and whether these changes are related to changes in fecal incontinence score. METHODS Consenting consecutive patients (n=266) with fecal incontinence (91% women; mean age, 59 years) underwent anorectal manometry, anal and rectal mucosal sensitivity measurements, and rectal capacity measurement at baseline and after nine sessions of standardized pelvic floor physiotherapy. These findings were compared with changes in Vaizey incontinence score. RESULTS On follow-up 3 months after physiotherapy, squeeze pressure (p=0.028), as well as urge sensation threshold (p=0.046) and maximum tolerable volume (p=0.018), had increased significantly. The extent of improvement was not related to age, duration of fecal incontinence, menopause, and endosonography findings. All other anorectal functions did not change. An improvement in the Vaizey score was moderately correlated with an increase in incremental squeeze pressure (r=0.14, p=0.04) and a decrease in anal mucosal sensitivity threshold (r=0.20, p=0.01). CONCLUSIONS Physiotherapy improves squeeze pressure, urge sensation, and maximum tolerable volume. However, improved anorectal function does not always result in a decrease in fecal incontinence complaints.

Abstract
Faecal incontinence is a common multifactorial disorder. Major causes of faecal incontinence are related to vaginal delivery and prior anorectal surgery. In addition to medical history and physical examination, several anorectal functional tests and imaging techniques can be used to assess the underlying pathophysiology and to guide treatment planning in faecal incontinent patients. Anorectal functional tests provide functional information, but the potential strength comes from combining test results. Imaging techniques, including defecography, endoanal sonography, and magnetic resonance (MR) imaging, provide structural information about the anorectal region with a direct clinical impact. The major role of imaging techniques in faecal incontinence is visualising the structural and functional integrity of the anal sphincter complex. Both two-dimensional endoanal sonography and endoanal MR imaging are accurate tools to depict anal sphincter defects. The major advantage of endoanal MR imaging is the accurate demonstration of external anal sphincter atrophy. Recent studies have suggested that external phased array MR imaging and three-dimensional endoanal sonography are also valuable tools in the diagnostic work up of faecal incontinence. Decisions about the preferred technique will mainly be determined by availability and local expertise. This article demonstrates the current role of tests, predominantly imaging tests, in the diagnostic work up of faecal incontinence.

Abstract
The neurophysiological techniques currently available to evaluate anorectal disorders include concentric needle electromyography (EMG) of the external anal sphincter, anal nerve terminal motor latency (TML) measurement in response to transrectal electrical stimulation or sacral magnetic stimulation, motor evoked potentials (MEPs) of the anal sphincter to transcranial magnetic cortical stimulation, cortical recording of somatosensory evoked potentials (SEPs) to anal nerve stimulation, quantification of electrical or thermal sensory thresholds (QSTs) within the anal canal, sacral anal reflex (SAR) latency measurement in response to pudendal nerve or perianal stimulation, and perianal recording of sympathetic skin responses (SSRs). In most cases, a comprehensive approach using several tests is helpful for diagnosis: needle EMG signs of sphincter denervation or prolonged TML give evidence for anal motor nerve lesion; SEP/QST or SSR abnormalities can suggest sensory or autonomic neuropathy; and in the absence of peripheral nerve disorder, MEPs, SEPs, SSRs, and SARs can assist in demonstrating and localizing spinal or supraspinal disease. Such techniques are complementary to other methods of investigation, such as pelvic floor imaging and anorectal manometry, to establish the diagnosis and guide therapeutic management of neurogenic anorectal disorders.

Abstract
BACKGROUND AND AIMS A randomised trial was undertaken to compare the clinical and functional results of two novel transanal stapled techniques in patients with outlet obstruction syndrome. MATERIALS AND METHODS Ninety-six females with outlet obstruction were treated with medical therapy and biofeedback for 2 months; 67 non-responders were evaluated by the Constipation Scoring and Continence Grading Systems, clinical examination, endoscopy, dynamic defecography, anorectal manometry, transanal ultrasound and anal EMG, and 50 of them, all affected with descending perineum, intussusception and rectocele, were randomly assigned to two groups and operated on: 25 patients (mean age 53.2+/-15.3 years) underwent a single Stapled Trans-Anal Prolapsectomy, associated with Perineal Levatorplasty (STAPL Group), and the other 25 (mean 54.6+/-14.2 years) underwent a double Stapled Trans-Anal Rectal Resection (STARR Group). Patients were followed-up for a mean period of 23.4+/-5.1 months in STAPL Group and 22.3+/-4.8 in STARR Group. RESULTS STARR Group showed a significantly (p<0.0001) lower pattern of postoperative pain and a greater decrease (P=0.0117) of the rectal sensitivity threshold volume; otherwise, no differences were found in operative time, hospital stay, or time of inability to work. Complications included delayed healing of the perineal wound (ten), dyspareunia (five), urinary retention (two) and stenosis (one) in STAPL Group, and urge to defecate (four), transitory incontinence to flatus (two), urinary retention (two), bleeding (one) and stenosis (one) in STARR Group. All constipation symptoms significantly improved without worsening of anal continence and with excellent/good outcome at 20 months in 76 and 88% of patients of STAPL Group and STARR Group, respectively. Seven patients of STAPL Group had a little residual rectocele, while both intussusception and rectocele were corrected in all patients of STARR Group. Neither operation modified anal pressures or caused lesions of anal sphincters. CONCLUSIONS Both techniques are safe and effective in the treatment of outlet obstruction; nevertheless, the double Stapled Trans-Anal Rectal Resection seems to be preferable due to less pain, absence of dyspareunia, reduced rectal sensitivity threshold volume and absence of residual rectocele at defecography.

BACKGROUND There is a need for better tolerated drugs to normalize bowel function in chronic constipation. Prucalopride is a highly selective, specific, serotonin4 receptor agonist with enterokinetic properties. AIM To evaluate the effects of prucalopride on bowel function, colonic transit and anorectal function in patients with chronic constipation. METHODS Twenty-eight patients were enrolled in this double-blind, placebo-controlled, crossover study (prucalopride: 1 mg, n=12; 2 mg, n=16). Patients kept a bowel function diary. Colonic transit times and anorectal function (anal manometry, rectal sensitivity and rectal compliance) were assessed. RESULTS Prucalopride (1 mg) compared to placebo significantly increased the mean number of spontaneous complete, spontaneous and all bowel movements per week. Prucalopride (1 mg) significantly decreased the percentage of bowel movements with hard/lumpy stools and straining and increased the urge to defecate. Prucalopride (1 and 2 mg) decreased the mean total colonic transit time by 12.0 h (prucalopride 42.8 h vs. placebo 54.8 h; P=0.074). No statistically significant effects were found in any of the anorectal function parameters. Prucalopride was well tolerated. There were no clinically relevant changes in standard safety parameters. CONCLUSIONS Prucalopride significantly improves stool frequency and consistency, and the urge to defecate, and may decrease colonic transit times in patients with chronic constipation.

Abstract
INTRODUCTION To reduce pouch related complications after restorative proctocolectomy, an alternative procedure was developed, the ileo neo-rectal anastomosis (INRA). This technique consists of rectal mucosa replacement by ileal mucosa and straight ileorectal anastomosis. Our study provides a detailed description of the functional results after INRA. PATIENTS AND METHODS Eleven patients underwent an INRA procedure with a temporary ileostomy. Anorectal function tests were performed two months prior to and six and 12 months after closure of the ileostomy and comprised: anal manometry, ultrasound examination, rectal balloon distension, and transmucosal electrical nerve stimulation (TENS). Function was subsequently related to the histopathology of rectal biopsy samples. RESULTS Median stool frequency decreased from 15/24 hours (10-25) to 6/24 hours (4-11) at one year. All patients reported full continence. Anal sensibility, and resting and squeeze pressures did not change after INRA. Rectal compliance decreased (2.1 (0.7-2.8) v 1.5 (0.4-2.2) and 1.4 (0.8-3.7) ml/mm Hg (p=0.03)) but the maximum tolerated volume increased (70 (50-118) v 96 (39-176) (NS) and 122 (56-185) ml (p=0.03)). Decreasing rectal sensitivity was found: the maximum tolerated pressure increased (14 (8-24) v 22 (8-34) (NS) and 26 (14-40) (p=0.02)) and the rectal threshold for TENS displayed a similar tendency. All patients displayed a low grade chronic inflammatory infiltrate in neorectal biopsy samples before closure of the ileostomy, with no change during follow up. CONCLUSIONS The technique of INRA provides a safe alternative for restorative surgery. Stool frequency after INRA improves with time and seems to be related to decreasing sensitivity and not to histopathological changes in the neorectum. Furthermore, after the INRA procedure, all patients reported full continence.

Abstract
Rectal prolapse can be diagnosed easily by having the patient strain as if to defecate. A laparoscopic rectopexy should be recommended. Intussusception is more an epiphenomenon than a cause of defecatory disorder and should be managed conservatively. Solitary rectal ulcer syndrome is a consequence of chronic straining, and therapy should include restoring a normal defecation habit. Rectocele should be left alone; an operation may be considered if it is larger than 3 cm and is causing profound symptoms despite maximizing medical therapy for the associated defecation disorder.

Abstract
BACKGROUND Faecal incontinence is a debilitating problem with significant medical, social and economic implications. Treatment options include conservative, non-operative interventions (e.g. pelvic floor muscle training, biofeedback, drugs) and surgical procedures. Surgery is used in selected groupsof people when the structural and functional defects in the pelvic floor muscles or the anal sphincter complex can be corrected mechanically. OBJECTIVES To assess the effects of established surgical techniques for the treatment of faecal incontinence in adults who do not have rectal prolapse. Our aims were firstly to compare surgical management with non-surgical management and secondly, to compare the various surgical techniques. SEARCH STRATEGY We searched the Cochrane Incontinence Group trials register, the Cochrane Colorectal Cancer Group trials register, the Cochrane Controlled Trials Register (Issue 2, 1999), Medline (up to March 1999), Embase (1998 up to January 1999), Sigle (1980 up to December 1996), Biosis (1998 up to March 1999), SCI (1998 up to March 1999), ISTP (1982 up to March 1999) and the reference lists of relevant articles. We specifically hand searched the British Journal of Surgery from 1995 to 1998 and the Diseases of the Colon and Rectum from 1995 to 1998. We also perused the proceedings of the Association of Coloproctology, meeting 1999. Date of the most recent literature searches: March 1999. SELECTION CRITERIA All randomised or quasi-randomised trials of surgery in the management of adult faecal incontinence (other then surgery for rectal prolapse). DATA COLLECTION AND ANALYSIS Two reviewers independently selected studies from the literature, extracted data and assessed the methodological quality of eligible trials. The three primary outcome measures were: change or deterioration in incontinence, failure to achieve full continence, and the presence of faecal urgency. MAIN RESULTS Four trials were included with a total sample size of 110 participants. All trials excluded women with anal sphincter defects detected by endoanal ultrasound examination. No trial included a group managed non-surgically. Two trials (56 participants) compared three approaches to pelvic floor repair (anterior levatorplasty, postanal repair and their combination total pelvic floor repair). One trial (30 participants) evaluated adding plication of the anal sphincter to total pelvic floor repair. The fourth trial (24 participants) compared a neosphincter procedure with total pelvic floor repair. No differences in the primary outcomes were detected, but data were few and inconsistently reported. REVIEWER'S CONCLUSIONS The small number of relevant trials identified together with their small sample sizes and other methodological weaknesses severely limit the usefulness of this review for guiding practice. It was impossible to identify or refute clinically important differences between the alternative surgical procedures. Larger rigorous trials are needed.

Abstract
BACKGROUND Prucalopride (PR) is a novel 5-HT4 agonist enterokinetic compound. AIM To evaluate its effect on bowel function, gut transit and anorectal function in healthy volunteers using a double-blind, placebo-controlled crossover study. METHODS Twenty-four healthy volunteers (12 men, 12 women, mean age 25 years, range 20-53 years) were randomly assigned to 1 mg/placebo or 2 mg/placebo (PL). The trial consisted of five consecutive 1 week periods: no drug treatment, PR treatment or PL, washout, PL or PR, no treatment. Subjects maintained a diary of bowel function during the entire study period. Total intestinal transit time (TITT), mean colonic transit time (MCTT) and anorectal function (anal manometry, rectal sensitivity and rectal compliance) were assessed at the end of both treatment periods. Electrocardiography and blood sampling were performed for safety analysis; blood sampling was also used to check compliance. RESULTS No subjects withdrew from the study. Treatment with PR 2 mg showed a statistically significant increase in mean number of weekly stools (11.5 vs. 7.1 compared to PL, P = 0.04) and in the percentage of loose/watery stools (48 vs. 12% compared to PL, P = 0.005). Within 1 week, stool frequency and consistency returned to baseline values when treatment was stopped. MCTT was shortened significantly with both doses, i.e. from 35 h on PL to 25 h on PR 1 mg (P = 0.01) and from 43 h on PL to 22 h on PR 2 mg (P = 0.02). Anorectal function was unaffected by PR. Transient and moderate headache occurred in nine subjects during PR treatment and in six subjects during PL treatment. CONCLUSION Prucalopride is well tolerated by healthy subjects and has a marked and consistent effect on stool frequency and consistency, and on colonic transit. In the present study prucalopride did not affect visceral sensitivity or sphincter function. It holds promise for patients with slow transit constipation.

Abstract
BACKGROUND This study was designed to investigate the long-term clinical and anorectal functional results after primary repair of a third-degree obstetrical perineal rupture. METHODS One hundred and fifty-six consecutive women who had a primary repair of a third-degree perineal rupture were sent a questionnaire and asked to undergo anorectal function testing (anal manometry, anorectal sensitivity, anal endosonography and pudendal nerve terminal motor latency (PNTML)) RESULTS: Some 117 women (75 per cent) responded. Anal incontinence was present in 47 women (40 per cent); however, in most cases only mild symptoms were present. In 40 women additional anorectal function tests were performed and compared with findings in normal controls. Mean(s.d.) maximum squeeze pressure (31(15) versus 63(17) mmHg, P< 0.001) was decreased and first sensation to filling of the rectum (88(47) versus 66(33) ml, P=0.03) and anal mucosal electrosensitivity (4.7(1.7) versus 2.5(0.8) mA, P=0.003) were increased compared with values in normal controls. In 35 women (88 per cent) a sphincter defect was found with anal endosonography. Factors related to anal incontinence were the presence of a combined anal sphincter defect (relative risk (RR) 1.7 (95 per cent confidence interval (c.i.) 1.1-2.8)) or subsequent vaginal delivery (RR 1.6 (95 per cent c.i. 1.1-2.5)). CONCLUSION Anal incontinence prevails in 40 per cent of women 5 years after primary repair of a third-degree perineal rupture. The presence of a combined sphincter defect or subsequent vaginal delivery increase the risk of anal incontinence.
