Belgian experience with dynamic graciloplasty for faecal incontinence

BACKGROUND: Dynamic graciloplasty (DGP) is an option in patients with end-stage faecal incontinence. The aim of this retrospective multicentre study was to assess early and late outcome after DGP. METHODS: Sixty consecutive patients with congenital (14) or acquired (40) faecal incontinence or who had undergone total anorectal reconstruction (six) underwent DGP. Patients were followed up for a median of 48 (range 13-117) months. RESULTS: There were no deaths; 75 complications that required 61 reoperations were observed in 44 patients. Loss of muscle stimulation occurred in 22 patients, more frequently after direct nerve stimulation. Evacuation difficulties occurred in 12 patients. Overall, DGP failed in 27 patients, of whom seven had stoma construction. At follow-up, continence to solid stool without stoma was obtained in 47 of 60 patients, although 26 required use of antegrade continence enemas or other measures. Functional outcome was related to the presence of a functioning DGP and a short delay (less than 50 days) of muscle training after transposition. CONCLUSION: DGP is a major operation with a high morbidity rate; it requires experience and early muscle training. The outcome after DGP should be compared prospectively with that after implantation of an artificial sphincter or other less expensive alternatives.     

Long-term follow-up of dynamic graciloplasty for faecal incontinence

OBJECTIVE: This paper presents the long-term morbidity, function and quality of life data for patients who have undergone dynamic graciloplasty (DGP) for faecal incontinence. PATIENTS AND METHODS: All patients (n = 38) who had undergone DGP at one institution between 1993 and 2003 are presented. Thirty-three were available for long-term follow-up (median 60 months) and completed a telephone questionnaire assessing quality of life (QOL), bowel and sexual function and patient satisfaction. All patients had interval anorectal physiology studies. RESULTS: At a median follow-up of 5 years, 72% had pain, swelling or paraesthesia in the donor leg and 27% had sexual dysfunction. Sixteen percent of patients had been converted to an end-colostomy for persisting incontinence and 11% for obstructed defaecation. All other patients have a normally functioning graciloplasty. Sixteen percent of patients reported a faecal continence score < 12. Of those patients with a functioning graciloplasty, 50% had obstructed defaecation and 64% reported that their bowel dysfunction had a negative impacted on their QOL. Age, medical comorbidity and anal manometry did not correlate with functional outcome. Quality of life scores and patient satisfaction scores correlated significantly with continence scores. There was a trend toward higher QOL and satisfaction scores with conversion to colostomy compared with a continence score > 12. Sixty percent of patients rated their satisfaction with DGP as 50% or better on a visual analogue scale, and this correlated strongly with the continence score at the time of the assessment (P < 0.001). CONCLUSION: Dynamic graciloplasty significantly improves patient quality of life and anal continence for some patients. Despite increased experience, morbidity remains high and long-term continence scores are poor in a majority of cases. Obstructed defaecation is a significant problem after graciloplasty and antegrade colonic enemas may be needed. Significant prognostic factors for obstructed defaecation remain to be identified. The mechanism of both continence failure and surgical morbidity remains poorly defined in many patients and requires further investigation. The individual patient can expect a 16% chance of normal faecal continence at 5 years, with at least one surgical morbidity as a result of the procedure.     

Outcome and late functional results after anastomotic leakage following mesorectal excision for rectal cancer

BACKGROUND: Few studies have evaluated the long-term functional outcome after anastomotic leakage in the treatment of rectal cancer. METHODS: Between 1993 and 1998, 147 patients were admitted with resectable rectal carcinoma, and 92 underwent low anterior resection (LAR). Seventeen patients (18 per cent) developed clinical anastomotic leakage. The functional outcome of 11 of 12 patients, in whom the stoma was subsequently closed and bowel continuity was restored without stricture, was compared with that of 11 matched patients who had undergone LAR without leakage. Anorectal manovolumetry and symptom scoring on visual analogue scales were done 12-48 months after stoma closure. RESULTS: Nine patients made an uneventful recovery after the initial treatment of anastomotic leakage. Eight developed serious septic complications, four of whom had a pelvic abscess, but there was no death. Five patients had chronic complications that precluded closure of the stoma. Patients who had experienced leakage showed reduced neorectal capacity (120 versus 180 ml; P = 0.04), more evacuation problems (P = 0.02), and a trend towards more faecal urgency (P = 0.09) and incontinence (P = 0.06) than control patients. CONCLUSION: Stoma closure was not possible in five of 17 patients who had experienced anastomotic leakage. Patients who had the stoma closed had impaired long-term anorectal function compared with control patients without leakage.     

Late adverse effects of short-course preoperative radiotherapy in rectal cancer

BACKGROUND: Preoperative radiotherapy improves local control and survival in rectal cancer, but there are few reports on long-term morbidity. The aims of this study were to compare long-term morbidity and quality of life in patients undergoing rectal cancer surgery with or without preoperative radiotherapy. METHODS: A total of 252 patients, randomized within the two Stockholm trials on preoperative radiotherapy in rectal cancer, were alive at a mean of 15 years after surgery. Some 139 of these patients were available for follow-up by questionnaires and clinical examination. Questionnaires regarding medical history and quality of life were completed by all patients. All patients had a clinical examination, and those without a stoma underwent rigid sigmoidoscopy. RESULTS: Overall, patients who had preoperative radiotherapy experienced significantly more late complications than those who did not (69 versus 43 per cent; P = 0.002). This morbidity consisted mainly of cardiovascular disease (35 versus 19 per cent; P = 0.032), faecal incontinence (12 of 21 versus 11 of 42 patients having anterior resection; P = 0.013) and urinary incontinence (45 versus 27 per cent; P = 0.023). No significant differences between groups were found for hip or pelvic fractures, small bowel obstruction or global quality of life. CONCLUSION: Preoperative short-course, high-dose radiotherapy in patients with rectal cancer increases the risk of anal and urinary dysfunction, and may lead to increased cardiovascular morbidity, at long-term follow-up.     

Cost‐effectiveness analysis of sacral neuromodulation for faecal incontinence in the Netherlands

Aim Sacral neuromodulation (SNM) plays a major part in the algorithm of management of faecal incontinence, but there are limited data on its cost‐effectiveness. This study aimed to analyse this and the quality‐adjusted life‐years (QALYs) associated with two different treatment algorithms. The first (SNM?) included use of an artificial sphincter [dynamic graciloplasty (DGP) (50%) and artificial bowel sphincter (ABS) (50%)]. The second (SNM+) included SNM (80% of cases) and artificial sphincter (DGP 10%; ABS 10%) The incidence of sphincteroplasty was assumed to be equal in both algorithms. Method A Markov model was developed. A hypothetical cohort of patients was run through both strategies of the model. A mailed EuroQoL‐5D questionnaire was used to determine health‐related quality of life. Costs were reproduced from the Maastricht University Medical Centre prospective faecal incontinence database. The time scale of the analysis was 5 years. Results The former treatment protocol cost €22 651 per patient and the latter, after the introduction of SNM, cost €16 473 per patient. The former treatment protocol resulted in a success rate of 0.59 after 5 years, whereas with the introduction of SNM this was 0.82. Adhering to the former treatment protocol yielded 4.14 QALYs and implementing the latter produced 4.21 QALYs. Conclusion The study demonstrated that introducing SNM in the surgical management algorithm for faecal incontinence was both more effective and less costly than DGP or ABS without SNM. This justifies adequate funding for SNM for patients with faecal incontinence.     

Outcome of antegrade continence enema procedures for faecal incontinence in adults

BACKGROUND: Faecal incontinence has major consequences. Colostomy has been the mainstay of therapy when other options fail. Operations such as the Malone procedure have been proposed as an alternative. The aim of this study was to evaluate the outcomes and quality of life of patients having a Malone procedure for the treatment of faecal incontinence. METHODS: Charts of patients who had had a Malone procedure or equivalent between 1998 and 2004 were reviewed. The patients completed a Short Form (SF) 36 quality of life questionnaire. RESULTS: The study included 25 patients (17 female; median age 47 years). In seven, the appendix was used; an ileoneoappendicostomy was performed in the other 18. Three patients were lost to follow-up; the remaining 22 were followed for a median (range) of 21 (1-61) months. Five patients had a cutaneous stenosis; another had the appendicostomy removed and replaced by a colostomy. Four patients no longer used the stoma for irrigation. All other patients were completely clean except one, who reported occasional night-time seepage. The mean SF-36 showed a good physical recovery (43.9) but persisting psychological distress (36.0). CONCLUSION: The Malone procedure or equivalent achieves good results in the management of faecal incontinence, although psychological distress persists after surgery.     

Defunctioning stomas in patients with locally advanced rectal cancer prior to preoperative chemoradiotherapy

Objective A literature search did not produce any evidence‐based objective criteria to determine which patients with locally advanced rectal cancer would benefit from a defunctioning stoma prior to neoadjuvant chemoradiotherapy. Our criteria for formation of a defunctioning stoma are: faecal incontinence and inability to cannulate the tumour at colonoscopy. The aim of this study was to examine whether these current criteria are appropriate. Method Forty‐nine consecutive locally advanced rectal cancer patients treated from February 2003 to November 2006 were identified from our colorectal database. All received long‐course chemoradiotherapy (Bossett regimen) and definitive surgery was performed 6–8 weeks later. Results Of the 49 patients, 31 presented with diarrhoea and two with faecal incontinence; nine patients were defunctioned by trephine stoma prior to treatment [cannulation impossible at colonoscopy (n = 8); faecal incontinence (n = 1)]. One patient with faecal incontinence refused early defunctioning stoma. Median hospital stay was 12 days (interquartile range: 7–30), and complications included pneumonia (n = 1) and peristomal cellulitis (n = 2). Of the 40 patients who went directly to neoadjuvant chemoradiotherapy, two subsequently required a defunctioning stoma for severe diarrhoeal symptoms during therapy. Eight patients had worsening diarrhoeal symptoms but tolerated treatment. Three patients, who had stoma formation, did not proceed to definitive surgery following neoadjuvant therapy: poor operative fitness (n = 2) and disease progression (n = 1). Conclusion Stenosis causing inability to cannulate the tumour at colonoscopy and faecal incontinence were the only objective indications for an early defunctioning stoma. Worsening diarrhoea during therapy (unless severe) did not appear to be a good indication for a defunctioning stoma.     

Long-term outcome of postanal repair in the treatment of faecal incontinence

BACKGROUND: Idiopathic faecal incontinence is a common debilitating problem; the results of surgical treatment are variable with only a small proportion of patients achieving full continence. OBJECTIVES: The aim of this study was to evaluate the long-term outcome of postanal repair in idiopathic faecal incontinence. PATIENTS AND METHODS: Patients who had postanal repair in Auckland between 1994 and 2001 were identified and mailed faecal incontinence severity index (FISI) and faecal incontinence quality of life (FIQOL) questionnaires. Preoperative and postoperative incontinence scores were compared and postoperative quality of life scores were calculated. RESULTS: Forty-seven of the 66 patients who had undergone postanal repair from 1994 to 2001 completed the FIQOL questionnaire. FISI scores were complete on 44 patients. Comparison of preoperative and postoperative FISI scores revealed an improvement with mean scores of 34 and 23, respectively (P = 0.0001). Thirty (68%) patients had improved, including four who were fully continent. Fourteen patients were the same or worse. CONCLUSIONS: Postanal repair provides lasting benefit for the majority of patients with faecal incontinence.     

Effect of stoma formation on bowel care and quality of life in patients with spinal cord injury

INTRODUCTION: Bowel management is a significant source of concern for patients with spinal cord injury (SCI) and may significantly alter quality of life. The effect of colostomy formation on both quality of life and time taken for bowel care is well recorded. We report our experience of intestinal stoma formation in SCI patients. METHODS: Medical records from the spinal unit, operating theatres and stoma clinics were reviewed to identify SCI patients for whom a stoma had been formed. Patients were interviewed using a standard questionnaire. Average age at injury was 29 years (range 6-62 years). Mean time from injury to stoma formation was 17 years (range 0-36.25 years) and the mean period of poor bowel function prior to stoma was 8 years (range 1.5-25). RESULTS: The average time spent on bowel care per week decreased from 10.3 h (range 3.5-45) prior to stoma formation to 1.9 h (range 0.5-7.75) afterwards (P<0.0001, paired t-test). In all, 18 patients felt that a stoma gave them greater independence and quality of life was described as much better by 25 patients. Complications occurred in 14 patients - eight described leakage of mucus and occasionally blood and pus per rectum, three developed parastomal hernias and three developed bowel obstruction. CONCLUSION: Elective stoma formation is a safe and well-accepted treatment for the management of chronic gastrointestinal symptoms in patients with SCI.     

Postanal repair – do the long‐term results justify the procedure?

Objective Early outcomes after postanal repair (PAR) demonstrated excellent results but subsequent reports showed an ever declining success rate in maintaining continence. The aim of this study was to document long‐term continence after PAR and relate this to patient satisfaction and quality of life. Method Patients with neurogenic incontinence who underwent PAR from 1986 to 2002 were interviewed by telephone, utilizing a questionnaire which assessed continence, patient satisfaction, overall improvement, and quality of life. Results One‐hundred one patients from four surgeons were identified. Fifty‐four patients were excluded because of loss to follow‐up. Three had a stoma (two for incontinence), four had undergone a graciloplasty, leaving 57 patients (F = 53), mean duration of follow‐up of 9.1 years (2.2–18.7 years). Mean CCS was 11.7 (SD 7.4). 26% (n = 15) scored none to minimal incontinence (CCS 0–5), 26% moderate (CCS 6–12), and 48% (n = 27) severe incontinence (CCS 13–24). 79% (n = 45) were satisfied with the outcome. A low CCS significantly correlated with good patient satisfaction, and was influenced by high QOL score (P < 0.0001). A high CCS significantly correlated with high bowel frequency (P = 0.0007). A favourable CCS was associated with a good QOL, a shorter duration of follow‐up, and being able to distinguish flatus and stool. Conclusions In patients with neurogenic faecal incontinence selected following anorectal physiology studies, PAR remains a useful treatment. It is associated with low morbidity and results in a satisfactory long‐term subjective outcome, despite the fact that many patients have a high incontinence score.     

Outcome after restorative proctocolectomy in children and adolescents

Aim The results including function and quality of life (QOL) of restorative proctocolectomy (RPC) performed in children and adolescents with ulcerative colitis (UC), familial adenomatous polyposis (FAP) and idiopathic megarectum were determined. Method Twenty‐one patients of a median age of 15 (10–17) years underwent RPC between 1995 and 2006. The indication, use of covering ileostomy, morbidity and mortality were recorded. A structured questionnaire was completed by telephone interview to assess long‐term function. The Cleveland Clinic Scoring (CCS) System was used for the assessment of faecal incontinence and the modified McMaster proforma for QoL. Results There was no mortality. At a median follow‐up of 65.5 (26–168) months, all patients had an intact pouch. One had a long‐standing ileostomy. Median daytime and nocturnal stool frequencies were 4 (2–16) and 0 (0–3). The mean CCS was 1.47, with only one patient scoring more than 10. Eighteen of 20 patients were satisfied with the result; two patients had a worse QoL (McMaster score > 8). One patient had a permanent stoma following pouch sepsis and one had symptoms of pouchitis. Conclusion RPC can be performed in children and adolescents with good functional outcome and acceptable QoL.     

Prospective cohort study of high-volume transanal irrigation in patients with constipation and/or faecal incontinence

Aim

The aim of this work was to determine the clinical efficacy of high-volume transanal irrigation (TAI) in patients with constipation and/or faecal incontinence using validated symptom and quality of life questionnaires.

Method

This was a prospective cohort study of 114 consecutive patients with constipation and/or faecal incontinence (Rome IV defined) who started TAI. A comprehensive questionnaire was completed at baseline and 4, 12, 26 and 52 weeks’ follow-up. The primary objective was significant symptom reduction [≥30%; Cleveland Clinic Constipation Score (CCCS) and St Marks Incontinence Score (SMIS)] in those who continued TAI at 52 weeks. Secondary objectives were (1) continuation rates of TAI, (2) effect on quality of life (QoL) and (3) identification of predictors for continuation.

Results

A total of 59 (51.8%) patients with constipation, 26 (22.8%) with faecal incontinence and 29 (25.4%) with coexistent symptoms were included. At 52 weeks, 41 (36.0%) patients continued TAI, 63 (55.2%) stopped and 10 (8.8%) patients were lost to follow-up. In those who continued TAI at 52 weeks (n = 41), no reduction of constipation symptoms was observed. Median Patient Assessment of Constipation Quality of Life scores decreased on most domains, indicating QoL improvement. Reduction of faecal incontinence occurred in 5/9 (55.6%) patients with faecal incontinence and in 3/10 (30.0%) patients with coexistent symptoms. The median SMIS per-individual decreased in patients with coexistent symptoms (2; interquartile range 0–4; p = 0.023). Median Fecal Incontinence Quality of Life scores increased in most domains, indicating improved QoL. No clinical characteristics predicted continuation.

Conclusion

One-third (n = 41) of patients continued TAI at 52 weeks. In those who continued TAI at 52 weeks, symptoms of faecal incontinence (SMIS) were reduced but not constipation (CCCS). QoL related to both constipation and faecal incontinence improved. No clinical characteristics predicted continuation.     

Partial longitudinal resection of the anorectum and sphincter for very low rectal adenocarcinoma: a surgical approach to avoid permanent colostomy

Aim Abdominoperineal resection has been the standard procedure for low rectal cancer. The present study details a new technique, partial longitudinal resection of the anorectum and sphincter, and assesses the oncological and functional outcomes. Method Between January 2004 and April 2008, 12 patients underwent partial longitudinal resection of the anorectum and sphincter for low rectal cancer. All patients underwent a diverting ileostomy and received biofeedback training before stoma closure. Functional results were assessed by vector manometry, Wexner constipation score and Wexner incontinence score. The quality of life (QoL) was assessed using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ‐C30). Results There was no postoperative mortality and a R0 curative resection was confirmed in every case. Morbidity included anastomotic leakage in three patients, one of whom underwent reoperation, and stenosis in 11, which was successfully managed with dilatation. The patient who underwent reoperation was not included in the functional analysis. The 11 successful patients received biofeedback training for 1–4 months, and underwent ileostomy closure 6–12 months after surgery. No patient had severe faecal incontinence after stoma closure. The EORTC QLQ‐C30 global health status and QoL scores at 12 months after stoma closure were 50.4 ± 24.3, similar to preoperation scores of 52.3 ± 25.6 (P = 0.927), and not significantly different to scores for the healthy control population of 63.4 ± 23.5 (P = 0.539). No patients developed local recurrence during the median observation period (35.5 months). One patient had distant metastases at 24 months, and underwent resection of the left liver. Conclusion Curability and acceptable anal function can be obtained by partial longitudinal resection of the anorectum and sphincter in patients with very low rectal cancers. This technique is recommended as an alternative to abdominoperineal resection in patients with external sphincter muscle invasion or tumours located below the dentate line.     

Prevalence of anorectal dysfunction in women attending health care services

The aim of this study was to assess the prevalence of different bowel symptoms (constipation, faecal incontinence and faecal evacuation dysfunction) and associated urinary symptoms in women attending health care services. All women attending colposcopy clinics and general gynaecology clinics in a district general hospital in the southwest of England were invited to participate in the study. In addition, women attending the local family planning clinic were also recruited. Women attending these clinics routinely completed a history sheet and were asked to complete the Birmingham Bowel and Urinary Symptoms Questionnaire. Two hundred women participated in the study: 116 (64.4%) had at least one bowel symptom from the list in the questionnaire and 57 (31.6%) of women thought they had a bowel problem but only 26 (14.4%) consulted their family doctor regarding the problem while four (2.2%) were referred for specialist opinion. Six were unsure about their bowel symptoms. There were 46 (25.5%) of women who had constipation, 99 (55%) had faecal incontinence and 97 (53.8%) complained of faecal evacuation dysfunction. Only 48 (26.6%) of women were free of any bowel complaint. One patient with faecal incontinence discussed her problem with her midwife but no further action was taken as she was too embarrassed to discuss it with her doctor. Seventy-eight (43.3%) of patients had urinary symptoms. Fifty-five (30.5%) thought they had a urinary problem but only 29 (16.1%) consulted their doctor and 17 (9.4%) were referred for specialist opinion. Sixty-one (33.8%) of those who admitted to have urinary incontinence also had faecal incontinence. Forty-nine (27.2%) of the patients were free of all symptoms. The mode of delivery as well as previous surgery did not have any influence on urinary incontinence nor on anal incontinence. This study has demonstrated a high prevalence of bowel symptoms in women attending health care services.     

Neosphincter Surgery for Fecal Incontinence: A Critical and Unbiased Review of the Relevant Literature

Up until about 15 years ago the only realistic option for end-stage fecal incontinence was the creation of a permanent stoma. There have since been several developments. Dynamic graciloplasty (DGP) and artificial bowel sphincter (ABS) are well-established surgical techniques, which offer the patient a chance for continence restoration and improved quality of life; however, they are unfortunately associated with high morbidity and low success rates. Several trials have been done in an attempt to clarify the advantages and disadvantages of these methods and define their place in the second-line treatment of severe, refractory fecal incontinence. This review presents a critical and unbiased overview of the current status of neosphincter surgery according to the available data in the world literature.     

Sacral nerve stimulation for faecal incontinence: long-term outcome

Aim  The efficacy of sacral nerve stimulation (SNS) to treat faecal incontinence has been demonstrated in the short- and mid-term. We analysed SNS outcome in the first patients with a permanent neurostimulator in whom follow-up ranges up to 14 years.
Method  Of 12 patients who underwent SNS from 1994 to 1999, 9 were eligible for long-term analysis (defined as a minimum of 7 years). In 3 the device had to be removed because of pain or neurological disease. Functional outcome was monitored prospectively by standardized questionnaire. For efficacy, the recorded frequency of incontinent episodes over 2-week periods and the Wexner Score were obtained yearly after implant. Quality of life measures (FIQL scale [QoL]) were introduced in 1998. Stimulation parameter adjustments, battery longevity, and complications were documented.
Results  Mean follow-up in the nine patients was 9.8 years (range 7–14), over which time efficacy persisted. Clinical improvement was significant (baseline vs last follow-up): median percentage of incontinent bowel movements/week 40% (range 9–100) vs 0% (0–60%; P  = 0.008), median number of incontinent episodes/week, 9 (range 2–58) vs 0 (0–29; P  = 0.012); median Cleveland Clinic Score, 17 (range 12–19) vs 10 (3–14; P  < 0.007); QoL improved in all categories. Pulse generator exchange was required in eight of the nine patients after a mean of 7.4 years for battery fatigue (mean 2.1 V). Complications occurred in five of the original 12 and were therapy-related, but not technique-related, in four patients.
Conclusion  Sacral nerve stimulation is an effective and safe long-term treatment for faecal incontinence. Clinical outcome is stable over time.     

Use of a continent colonic conduit for treatment of refractory evacuatory disorder following construction of an electrically stimulated gracilis neoanal sphincter

BACKGROUND: This study reports the outcome from the addition of a continent colonic conduit (CCC) to an electrically stimulated gracilis neoanal sphincter in patients with severe evacuatory disorder following formation of a neosphincter for end-stage faecal incontinence. METHODS: One hundred and twenty patients had an electrically stimulated gracilis neoanal sphincter constructed for end-stage faecal incontinence. Seven patients developed severe evacuatory disorders; construction of a CCC was required in six patients and an antegrade continence enema procedure in one. RESULTS: Median follow-up of the seven patients was 77 (range 6-96) months. Six patients with evacuatory disorders had a successful outcome, defined as continence to solid and liquid stool as well as correction of the evacuatory disorder. A stoma was formed in one patient. Patients who had previously undergone anorectal reconstructive surgery were more likely to develop an evacuatory disorder following construction of an electrically stimulated gracilis neoanal sphincter than patients operated on for other reasons (chi2 = 28.13, 1 d.f., P < 0.001). CONCLUSION: Construction of a CCC is a useful technique for the majority of patients with severe evacuatory disorders following the formation of an electrically stimulated gracilis neoanal sphincter, for whom the only alternative would be an end stoma. A CCC may be incorporated with construction of an electrically stimulated gracilis neoanal sphincter in patients at significant risk of postoperative severe evacuatory disorders.     

Factors influencing changing bowel habits in patients undergoing sphincter-saving surgery for rectal cancer

A research survey research was conducted to identify factors affecting changes in bowel habits of rectal cancer patients undergoing sphincter-saving surgery and to provide basic information useful in nursing interventions supporting treatment for rectal cancer patients. The subjects were rectal cancer patients who had undergone sphincter-saving surgery over 2 years ago. The final analysis included 107 patients who had made outpatient visits to the colorectal surgery from 12th to 31st May, 2014. Collected data were processed with SPSS Version 21.0. Changes in bowel habits in the subjects were observed: frequent bowel movement in 74 patients (69.2%) and faecal incontinence in 48 (44.9%). Most of the patients used self-care to improve their bowel function including dietary modification (78.5%), regular exercise (72.0%) and pelvic floor exercise (34.6%). Frequent defecation was associated with adjuvant chemoradiation therapy (P < 0.001) and faecal incontinence was associated with age of ≥65 years (P = 0.019) and a group who underwent adjuvant radiation therapy (P < 0.001). It is necessary to give sufficient information about possible postoperative changes in bowel habits to patients with the risk factors before surgery.     

Percutaneous tibial nerve stimulation can improve symptoms and quality of life in selected patients with faecal incontinence – A single-centre 5-year clinical experience

IntroductionFaecal incontinence is a debilitating condition that affects a significant proportion of the population. Conservative management remains the mainstay of treatment but surgical intervention such as neuromodulation can be indicated in cases refractory to medical therapy.AimThe aim of this study was to review the outcomes of patients who underwent percutaneous tibial nerve stimulation (PTNS) for faecal incontinence and urgency in a single institution over five years.ResultsEighty-one patients completed the 12-week trial of PTNS with a success rate of 80% (n = 64/81). Rates of faecal incontinence and urgency were reduced from 13 episodes per fortnight to 3 and from 10 to 3 respectively. Over a median follow up of 2 years (range 0–5 years) reduction in rates of faecal urgency and incontinence were maintained. Quality of life parameters were measured using a variety of established questionnaires. Improvements were observed in the majority of parameters that were maintained throughout the follow up period.ConclusionPercutaneous tibial nerve stimulation is one of the forms of neuromodulation available for the treatment of faecal incontinence and urgency in patients who failed conservative management. This study has shown that in carefully selected, motivated patients, the use of PTNS in conjunction with regular counseling from a specialist practitioner in pelvic floor disorders can improve both the symptoms and quality of life of patients with faecal urgency and mild faecal incontinence with improvements in symptomology maintained for up to 5 years.     

A prospective study assessing anal plug for containment of faecal soilage and incontinence

Objective  Faecal incontinence is a common and embarrassing problem for many individuals. Some patients remained symptomatic despite the availability of different treatments. There is a limited range of commercially available products designed to cope with faecal incontinence. The anal plug has been developed to contain the loss of stool. This study aimed to evaluate the use of anal plug in Asian patients with intractable faecal soilage and incontinence judged by clinical and functional outcomes.
Method  A prospective study of consecutive patients with intractable faecal incontinence was carried out. Suitable patients tested the anal plug for 3 weeks. They completed a structured questionnaire on its use including the ASCRS quality of life questionnaire for faecal incontinence.
Results  Thirty patients, median age 63 (interquartile range 52–70) years, participated in the trial. Nineteen of 30 patients were comfortable wearing the plug, seven patients withdrew from the study because of discomfort, and four had tolerable discomfort and managed to complete the trial protocol. Patients who tolerated the plug found that it was highly successful in controlling faecal incontinence. Twenty-one of 30 patients wished to continue to use the plug regularly after the study. There was a trend toward improvement in quality of life scores during the study.
Conclusion  The anal plug was effective in containing faecal incontinence and was well tolerated in the majority of patients selected for this treatment.
