Incontinence severity and QOL scales for fecal incontinence

Diagnostic tools for fecal incontinence: Scoring systems are the crucial first step

The main aim of this editorial is to comment on the recent article published by Garg et al in the World Journal of Gastroenterology 2023; 29: 4593-4603. This original research presents a new scoring system for fecal incontinence. Fecal incontinence is a chronic disease with a severe impact on the quality of life of the patients. Substantial social stigmatization often leads to significant underreporting of the condition even during visits to a specialist and could lead to further mismanagement or non-existent management of the disease. An important fact is that patients are often unable to describe their condition when not asked precisely defined questions. This problem is partially resolved by scoring questionnaires. Several scoring systems are commonly used; however, each of them has their shortcomings. For example, the absence of different kinds of leakage besides flatus and stool could further lead to underscoring the incontinence severity. Therefore, there has long been a call for a more precise scoring system. The correct identification of the presence and severity of fecal incontinence is paramount for further diagnostic approach and for choosing the appropriate therapy option. This editorial describes fecal incontinence, its effect on quality of life in general and further evaluates the diagnostic approach with a particular focus on symptom scoring systems and their implications for clinical practice.

The rectum, anal sphincter and puborectalis muscle show different contraction wave forms during prolonged measurement with a simulated feces

Contractile patterns in rectum, puborectalis muscle and anal sphincter must be studied to understand defecation. Six subjects had contractile waveforms studied with Fecobionics. Symptom questionnaires, balloon expulsion test and anorectal manometry were done for reference. The Fecobionics bag was filled in rectum to urge-to-defecate volume and measurements were done for 4 h before the subjects attempted to evacuate the device. Pressures and bend angle (BA) variations were analyzed with Fast Fourier Transformation. Four normal subjects exhibited low frequency waves (< 0.06 Hz) for pressures and BA. The waves were uncoordinated between recordings, except for rear and bag pressures. Peak wave amplitudes occurred at 0.02-0.04 Hz. Pressures and the BA differed for peak 1 (p < 0.001) and peak 2 amplitudes (p < 0.005). The front pressure amplitude was bigger than the others (rear and BA, p < 0.05; bag, p < 0.005) for peak 1, and bigger than bag pressure (p < 0.005) and BA (p < 0.05) for peak 2. One subject was considered constipated with lower front pressure amplitudes compared to normal subjects and increased amplitudes for other parameters. The sixth subject was hyperreactive and differed from the other subjects. In conclusion, the rectum, anal sphincter and puborectalis muscle showed different contraction waves during prolonged measurements. The data call for larger studies to better understand normal defecation, feces-withholding patterns, and the implications on anorectal disorders.

Fecal incontinence was associated with depression of any severity: insights from a large cross-sectional study

OBJECTIVE

Current studies on the association between fecal incontinence (FI) and depression are very limited, and most of them are restricted to women or elderly patients. This study aims to evaluate in detail the association between FI and depression among US adults.

METHODS

13,480 adults aged 20 years and older were selected from the National Health and Nutrition Examination Survey 2005-2010. Monthly loss of solid, liquid, or mucous stool was defined as FI. Clinical depression and depression severity were assessed by the validated Patient Health Questionnaide-9 (PHQ-9). Models of multivariate logistic regression were used to calculate adjusted odds ratios (ORs). A subgroup analysis was carried out to ensure that the results were stable.

RESULTS

After adjusting for covariates such as demographics, risk behaviors and associated comorbidities, the PHQ-9 score and clinical depression were both significantly associated with FI, with ORs and 95%CIs of 1.11 (1.10-1.13) and 3.01 (2.53-3.57). Depression of all severities was also significantly associated with FI. The ORs and 95%CIs of FI with mild depression, moderate depression, and moderately severe to severe depression were 2.29 (1.96-2.68), 3.44 (2.77-4.27) and 4.65 (3.61-6.00), respectively. Subgroup analyses showed no statistically significant interactions (P > 0.05).

CONCLUSIONS

In conclusion, FI significantly associated with depression of any severity. Like the elderly or female patients with FI, young and middle-aged or men with FI are also at high risk of depression and should also be the focus of depression screening and early intervention.

The Mexican consensus on fecal incontinence

Fecal incontinence is the involuntary passage or the incapacity to control the release of fecal matter through the anus. It is a condition that significantly impairs quality of life in those that suffer from it, given that it affects body image, self-esteem, and interferes with everyday activities, in turn, favoring social isolation. There are no guidelines or consensus in Mexico on the topic, and so the Asociación Mexicana de Gastroenterología brought together a multidisciplinary group (gastroenterologists, neurogastroenterologists, and surgeons) to carry out the «Mexican consensus on fecal incontinence» and establish useful recommendations for the medical community. The present document presents the formulated recommendations in 35 statements. Fecal incontinence is known to be a frequent entity whose incidence increases as individuals age, but one that is under-recognized. The pathophysiology of incontinence is complex and multifactorial, and in most cases, there is more than one associated risk factor. Even though there is no diagnostic gold standard, the combination of tests that evaluate structure (endoanal ultrasound) and function (anorectal manometry) should be recommended in all cases. Treatment should also be multidisciplinary and general measures and drugs (lidamidine, loperamide) are recommended, as well as non-pharmacologic interventions, such as biofeedback therapy, in selected cases. Likewise, surgical treatment should be offered to selected patients and performed by experts.

Outcomes following anastomotic leak from rectal resections, including bowel function and quality of life

PURPOSE

Anastomotic leak (AL) is an uncommon but potentially devastating complication after rectal resection. We aim to provide an updated assessment of bowel function and quality of life after AL, as well as associated short- and long-term outcomes.

METHODS

A retrospective audit of all rectal resections performed at a colorectal unit and associated private hospitals over the past 10 years was performed. Relevant demographic, operative, and histopathological data were collected. A prospective survey was performed regarding patients' quality of life and fecal continence. These patients were matched with nonAL patients who completed the same survey.

RESULTS

One hundred patients (out of 1,394 resections) were included. AL was contained in 66.0%, not contained in 10.0%, and only anastomotic stricture in 24.0%. Management was antibiotics only in 39.0%, percutaneous drainage in 9.0%, operative abdominal drainage in 19.0%, transrectal drainage in 6.0%, combination of percutaneous drainage and transrectal drainage in 2.0%, and combination abdominal/transrectal drainage in 1.0%. The 1-year stoma rate was 15.0%. Overall, mean Fecal Incontinence Severity Instrument scores were higher for AL patients than their matched counterparts (8.06±10.5 vs. 2.92±4.92, P=0.002). Patients with an AL had a mean EuroQol visual analogue scale (EQ-VAS) of 76.23±19.85; this was lower than the matched mean EQ-VAS for non-AL patients of 81.64±18.07, although not statistically significant (P=0.180).

CONCLUSION

The majority of AL patients in this study were managed with antibiotics only. AL was associated with higher fecal incontinence scores in the long-term; however, this did not equate to lower quality of life scores.

Short- and long-term outcomes of sphincteroplasty for anal incontinence related to obstetric injury: a systematic review

Anal incontinence is a frequent pathological condition with devastating impact on quality of life. The prevalence is approximately 15% of the population, with higher incidence reported in the elderly and multiparous women, and several factors have a major role in its pathogenesis, such as anatomical sphincter defects (Glasgow and Lowry in Dis Colon Rectum 55(4): 482-490, 2012), delivery injuries, and colorectal, uro-gynecological, and perineal surgery. The direct surgical approach is the gold standard treatment for fecal incontinence, especially through anterior sphincteroplasty, although a permanent defect of continence persists over time. The aim of our study is to evaluate, throughout a systematic review of the literature, the short- and long-term outcomes of sphincteroplasty performed for obstetric injuries anal incontinence. A systematic review of the studies published in the literature from January 2000 to December 2021 was performed in accordance with the PRISMA guidelines. Of the 2543 studies extrapolated, only eight fulfilled the inclusion criteria and were admitted represented by retrospective and prospective studies. The data analyzed from the included studies were number and mean age of the female population, and incontinence improvement with preoperative and postoperative short- and long-term outcomes, as reported by QoL questionaries and incontinence scores. Overall 355 patients with obstetric sphincter damage underwent sphincteroplasty with an anterior external sphincter overlapping procedure. A consistent improvement in fecal incontinence at short-term follow-up with relative improvement in QoL was reported. In 7 of 8 studies, the authors found a progressive worsening of the incontinence symptoms on the long-term follow-up. However, it is not clear whether the decrease in long-term continence results is parallel to a simultaneous decrease in QoL scores. Nevertheless, compared to the preoperative findings, the improvement was maintained in the long-term follow-up. Despite the limited data in the literature, a properly performed sphincteroplasty can guarantee a consistent improvement of the continence in short term with encouraging outcomes, especially for solid stool continence, in long time. We believe that anterior sphincteroplasty, as a low cost, feasible, and safe procedure, still has a role in the treatment of fecal incontinence for obstetric injury. Further large cohort randomized clinical trials are necessary to validate these results.

Co-occurrence of fecal incontinence with constipation or irritable bowel syndrome indicates the need for personalized treatment

BACKGROUND

This study aimed to compare the prevalence and symptoms of fecal incontinence (FI) in relation to irritable bowel syndrome (IBS-associated FI), constipation (constipation-associated FI), and isolation (isolated FI).

METHODS

Data were analyzed from 3145 respondents without organic comorbidities known to influence defecation function from the general Chinese population who filled in the online Groningen Defecation and Fecal Continence questionnaire. FI, IBS, and constipation were evaluated with the Rome IV criteria.

KEY RESULTS

The prevalence of FI was 10.5% (n = 329) in the non-comorbidity group. After multivariable logistic regression analysis, IBS (odds ratio [OR]: 12.55, 95% confidence interval [CI]: 9.06-17.36) and constipation (OR: 4.38, 95% CI: 3.27-5.85) were the most significant factors contributing to FI. Based on this finding, 106/329 (32.2%) had IBS-associated FI, 119/329 (36.2%) had constipation-associated FI, and 104/329 (31.6%) had isolated FI. Among the 329 FI respondents, there was a high prevalence of IBS and constipation-related symptoms, including abdominal pain (81.5%) and abdominal bloating (77.8%) for IBS and straining during defecation (75.4%), incomplete defecation (72.3%), defecation blockage (63.2%), anal pain during defecation (59.3%), and hard stools (24%) for constipation. The patients with IBS-associated FI asked for specialists' help less frequently than those with isolated FI. Interestingly, among the patients with constipation-associated FI, 56.3% used anti-diarrhea medicine.

CONCLUSIONS AND INFERENCES

The prevalence of IBS-associated FI, constipation-associated FI, and isolated FI is comparably high. It is important to diagnose and target the cause of FI to provide personalized and cause-targeting care instead of treating only the FI symptoms.

Association between fecal incontinence and suicidal ideation in adult Americans: Evidence from NHANES 2005-2010

OBJECTIVES

Currently, research on the relationship between fecal incontinence (FI) and suicidal ideation is very limited. This study aims to evaluate whether FI is associated with suicidal ideation among US adults.

METHODS

In this cross-sectional study, 13,480 adults aged 20 years and older were selected from the National Health and Nutrition Examination Survey 2005-2010. Monthly loss of solid, liquid, or mucous stool was defined as FI. As part of the Patient Health Questionnaire-9, item 9 assessed suicidal ideation. Models of multivariate logistic regression were used to calculate adjusted odds ratios. A subgroup analysis was carried out to ensure that the results were stable.

RESULTS

It was found that FI was associated with an increased risk of suicidal ideation after controlling for baseline characteristics, risk behaviors, and comorbid conditions such as depression (OR: 1.60, 95%CI: 1.24-2.08, P < 0.001). In subgroup analyses, FI remained significantly associated with suicidal ideation among participants aged 45 years and older, with odds ratios and 95% confidence intervals of 1.62 (1.11-2.38) and 2.49 (1.51-4.13), respectively. For age category <45 years, the association between FI and suicidal ideation weakened (OR: 1.02, 95%CI: 0.60-1.75, P = 0.932).

CONCLUSIONS

In conclusion, this study showed that FI was significantly associated with suicidal ideation. Patients aged middle-aged and older are at high risk and should be the focus of screening and timely intervention for suicidal ideation.

Defecatory Function Studies Using the Fecobionics Device Are Repeatable

BACKGROUND

Only limited data exist on repeatability of anorectal studies with the established physiological and clinical technologies for assessment of anorectal function. Fecobionics is a new multi-sensor simulated feces that provide data by integrating elements from current tests.

AIMS

To study repeatability of anorectal data obtained with the Fecobionics device.

METHODS

We assessed the database of Fecobionics studies to determine how many repeated studies were done. From a total of 260 Fecobionics studies, 19 subjects with repeated studies using approximately the same protocol and prototype were identified. Key pressure and bending parameters were assessed and the repeatability analyzed using Bland Altman plots. Furthermore, the inter- and intra-individual coefficient of variation (CV) were computed.

RESULTS

Fifteen subjects (5F/10 M) with repeated studies were normal subjects, three were patients with fecal incontinence and one subject suffered from chronic constipation. The main analysis was conducted on the cohort of normal subjects. The bias for 11 parameters were within the confidence interval, whereas two were slightly outside. The interindividual CV was lowest for the bend angle (10.1-10.7) and between 16.3 and 51.6 for the pressure parameters. The intra-individual CVs were approximately half of the inter-individual CVs, spanning from 9.7 to 27.6.

CONCLUSION

All data from normal subjects were within previously defined normality. The Fecobionics data showed acceptable repeatability with bias within the confidence limits for almost all parameters. The intra-individual CV was much lower than the inter-individual CV. Dedicated large-scale studies are warranted to evaluate the influence of age, sex, and disease on repeatability as well as comparing between technologies.

Anorectal volume-pressure relations, contraction work, and flow during defecation

Fecobionics is an integrated device that has shown promise for assessment of anorectal function. We used a wireless Fecobionics prototype to visualize defecatory patterns and to compute volume-pressure, contraction work, and flow. Twelve normal subjects were studied. The probe was 10 cm-long and contained pressure sensors and electrodes for impedance planimetry. Pressures, diameters, and volume data during defecation were analyzed. The bag was distended inside rectum to the urge-to-defecate level where after the subjects were asked to evacuate. The contraction work and defecatory flow were computed from the volume changes during expulsion. The minimum anal diameter during the evacuation was 17.6 ± 1.5 mm. The middle diameter recording was 10-20% lower than the front diameter channels and 10-20% bigger than the rear channels. The bag volume at urge correlated with the minimum diameter (r = 0.63). The diameter-pressure and volume-pressure loops were counterclockwise with phases of bag filling, isometric contraction, ejection and anal passage. The defecatory contraction work was 3520 ± 480 mL × cmH2O. The maximum flow during defecation was 302 ± 33 mL/s. The flow was associated with the anal diameter (r = 0.84) but not with the rectoanal pressure gradient (r = 0.14). Volume-pressure loops have a tremendous impact on the understanding of cardiopulmonary pathophysiology. Future studies will shed light on potential clinical impact in defecatory pathophysiology.

Fecobionics characterization of female patients with fecal incontinence

Defecatory disorders including fecal incontinence (FI) are diagnosed on the symptom pattern supplemented by anorectal manometry (ARM), the balloon expulsion test (BET), and endo-anal ultrasonography. In this study, we used a simulated stool named Fecobionics to study distinct defecation patterns in FI patients using preload-afterload diagrams and to provide comparative data on defecation indices (DIs) between passive and urge incontinent patients. All subjects had Fecobionics, endo-anal ultrasonography and ARM-BET done. The Fecobionics bag was distended in rectum until urge in 37 female patients (64.1 ± 1.5 yrs) and a group of normal subjects (NS, 12F, age 64.8 ± 2.8 yrs). Rear-front pressure (preload-afterload) diagrams and DIs were compared between groups. The FISI score in the patients was 8.6 ± 0.6. The NS did not report FI-related symptoms. All patients and NS defecated Fecobionics and ARM-BET within 2 min. The urge volume was 46.1 ± 3.6 and 35.3 ± 5.9 mL in the FI and normal groups (P > 0.1). The expulsion duration was 14.8 ± 2.4 and 19.8 ± 5.1 s for the two groups (P > 0.1). The preload-afterload diagrams demonstrated clockwise loops that clearly differed between the FI subtypes and NS. The DIs showed profound difference between patients and NS. Fecobionics data showed higher correlation with symptoms in FI patients than ARM-BET. Fecobionics obtained novel pressure signatures in subtypes of FI patients and NS. Fecobionics provides DI data that cannot be obtained with ARM-BET.

Feasibility study of defecation studied with a wireless Fecobionics probe in normal subjects

Several technologies have been developed for assessing anorectal function including the act of defecation. We used a new prototype of the Fecobionics technology, a multi-sensor simulated feces, to visualize defecatory patterns and introduced new metrics for anorectal physiology assessment in normal subjects. Fourteen subjects with normal fecal incontinence and constipation questionnaire scores were studied. The 10-cm-long Fecobionics device provided measurements of axial pressures, orientation, bending, and shape. The Fecobionics bag was distended to the urge-to-defecate level inside rectum where after the subjects were asked to evacuate. Physiological evacuation parameters were assessed. Special attention was paid to the Fecobionics rectoanal pressure gradient (F-RAPG) during evacuation. Anorectal manometry (ARM) and balloon expulsion test (BET) were done as references. The user interface displayed the fine coordination between pressures, orientation, bending angle, and shape. The pressures showed that Fecobionics was expelled in 11.5 s (quartiles 7.5 and 18.8s), which was shorter than the subjectively reported expulsion time of the BET balloon. Six subjects did not expel the BET balloon within 2 min. The F-RAPG was 101 (79-131) cmH₂ O, whereas the ARM-RAPG was -28 (-5 to -47) cmH₂ 0 (p < 0.001). There was no association between the two RAPGs (r²  = 0.19). Fecobionics showed paradoxical contractions in one subject (7%) compared to 12 subjects with ARM (86%). Fecobionics obtained novel physiological data. Defecatory patterns and data are reported and can be used to guide larger-scale studies in normal subjects and patients with defecatory disorders. In accordance with other studies, this Fecobionics study questions the value of the ARM-RAPG.

Fecobionics Evaluation of Biofeedback Therapy in Patients With Fecal Incontinence

INTRODUCTION

Biofeedback therapy (BFT) is a well-known treatment for functional anorectal disorders. The effect of BFT was monitored in fecal incontinence (FI) patients with the Fecobionics test and with the conventional technologies, anorectal manometry (ARM) and balloon expulsion test (BET).

METHODS

Studies were performed in 12 patients before and after 8 weeks of biofeedback training. The Fecal Incontinence Severity Index (FISI) score was obtained. Anal resting and squeeze pressures were measured before the bag was distended in the rectum until urge to defecate. Pressure recordings were made during Fecobionics evacuation.

RESULTS

BFT resulted in 24% reduction in FISI scores (P < 0.01). Seven patients were characterized as responders. Anal pressures, the urge-to-defecate volume, and defecatory parameters did not change significantly during BFT. For ARM-BET, the maximum anal squeeze pressure, the urge-to-defecate volume, and the expulsion time were lower after BFT compared with those before BFT (P < 0.05). For Fecobionics, the change in urge volume (r = 0.74, P < 0.05) and the change in defecation index (r = 0.79, P < 0.01) were associated with the change in FISI score. None of the ARM-BET parameters were associated with the change in FISI score. It was studied whether any pre-BFT data could predict treatment success. The Fecobionics expulsion duration and the defecation index predicted the outcome (P < 0.05). The defecation index had a sensitivity of 100% and a specificity of 72%. None of the ARM-BET parameters predicted the outcome (all P > 0.2).

DISCUSSION

Fecobionics was used as a tool to monitor the effect of BFT and proved better than conventional technologies for monitoring and predicting the outcome in the FISI score.

Do resistance exercises during biofeedback therapy enhance the anal sphincter and pelvic floor muscles in anal incontinence?

AIM

To determine if a biofeedback therapy that includes concentric resistance exercise for the anal sphincter muscles can improve muscle strength/function and improve AI symptoms compared to the traditional/non-resistance biofeedback therapy.

BACKGROUND

Biofeedback therapy is the current gold standard treatment for patients with anal incontinence (AI). Lack of resistance exercise biofeedback programs is a limitation in current practice.

METHODS

Thirty-three women with AI (mean age 60 years) were randomly assigned to concentric (resistance) or isometric (non-resistance) biofeedback training. Concentric training utilized the Functional Luminal Imaging Probe to provide progressive resistance exercises based on the patient's ability to collapse the anal canal lumen. Isometric training utilized a non-collapsible 10 mm diameter probe. Both groups performed a biofeedback protocol once per week in the clinic for 12 weeks and at home daily. High definition anal manometry was used to assess anal sphincter strength; symptoms were measured using FISI and UDI-6. 3D transperineal ultrasound imaging was used to assess the anal sphincter muscle integrity.

RESULTS

Concentric and isometric groups improved FISI and UDI-6 scores to a similar degree. Both the concentric and isometric groups showed small improvement in the anal high-pressure zone; however, there was no difference between the two groups. Ultrasound image analysis revealed significant damage to the anal sphincter muscles in both patient groups.

CONCLUSIONS

Concentric resistance biofeedback training did not improve the anal sphincter muscle function or AI symptoms beyond traditional biofeedback training. Anal sphincter muscle damage may be an important factor that limits the success of biofeedback training.

Ventral Prosthesis Rectopexy for obstructed defaecation syndrome: a systematic review and meta-analysis

Obstructed Defecation Syndrome (ODS) is a rather complex entity concerning mainly females and causing primarily constipation. Surgical treatment in the form of Ventral Prosthesis Rectopexy (VPR) has been proposed and seems to have the best outcomes. However, the selection criteria of patients to undergo this kind of operation are not clear and the reported outcomes are mainly short-term and data on long-term outcomes is scarce. This study assesses new evidence on the efficacy of VPR for the treatment of ODS, specifically focusing on inclusion criteria for surgery and the long-term outcomes. A search was performed of MEDLINE, EMBASE, Ovid and Cochrane databases on all studies reporting on VPR for ODS from 2000 to March 2020. No language restrictions were made. All studies on VPR were reviewed systematically. The main outcomes were intra-operative complications, conversion, procedure duration, short-term mortality and morbidity, length of stay, faecal incontinence and constipation, quality of life (QoL) score and patient satisfaction. Quality assessment and data extraction were performed independently by three observers. Fourteen studies including 963 patients were eligible for analysis. The immediate postoperative morbidity rate was 8.9%. A significant improvement in constipation symptoms was observed in the 12-month postoperative period for ODS (p < 0.0001). Current evidence shows that VPR offers symptomatic relief to the majority of patients with ODS, improving both constipation-like symptoms and faecal incontinence for at least 1-2 years postoperatively. Some studies report on functional results after longer follow-up, showing sustainable improvement, although in a lesser extent.

A novel bowel rehabilitation programme after total mesorectal excision for rectal cancer: the BOREAL pilot study

AIM

Low anterior resection syndrome (LARS) following sphincter-preserving surgery for rectal cancer has a high prevalence, with an impact on long-term bowel dysfunction and quality of life. We designed the bowel rehabilitation programme (BOREAL) as a proactive strategy to assess and treat patients with LARS. The BOREAL programme consists of a stepwise approach of escalating treatments: medical management (steps 0-1), pelvic floor physiotherapy, biofeedback and transanal irrigation (step 2), sacral nerve neuromodulation (step 3), percutaneous endoscopic caecostomy and anterograde enema (step 4) and definitive colostomy (step 5).

METHODS

A pilot study was undertaken to assess the feasibility of collecting LARS data routinely with the parallel implementation of the BOREAL programme. All patients who underwent total mesorectal excision for rectal cancer between February 2017 and March 2019 were included. LARS was assessed using the LARS score and the Wexner Faecal Incontinence score at 30 days and 3, 6, 9 and 12 months postoperatively. A good functional result was considered to be a combined LARS score <20 and/or a Wexner score <4.

RESULTS

In all, 137 patients were included. Overall compliance with the BOREAL programme was 72.9%. Major LARS decreased from 48% at 30 days postoperatively to 12% at 12 months, with a concomitant improvement in overall good function from 33% to 77%, P < 0.001. The majority of patients (n = 106, 77%) required medical management of their LARS.

CONCLUSION

The BOREAL programme demonstrates the acceptability, feasibility and effectiveness of implementing a responsive, stepwise programme for detecting and treating LARS.

Sequential assessment of bowel function and anorectal physiology after anterior resection for cancer: a prospective cohort study

AIM

The aim of this study was to investigate changes in bowel function and anorectal physiology (ARP) after anterior resection for colorectal cancer.

METHOD

Patients were recruited from November 2006 to September 2008. Cleveland Clinic Incontinence (CCI) scores and stool frequency were determined by patient questionnaires before surgery (t₀ ) and at three (t₃ ), six (t₆ ), nine (t₉ ) and 12 (t₁₂ ) months after restoration of intestinal continuity. ARP measurements were recorded at T₀ , T₃ and T₁₂ . Endoanal ultrasound was performed at T₀ and T₁₂ .

RESULTS

Eighty-nine patients were included. CCI score increased postoperatively then normalized, whereas stool frequency did not change. Patients who had neoadjuvant radiotherapy or a lower anastomosis had increased incontinence and stool frequency in the postoperative period, whereas those with defunctioning stomas or open surgery had increased stool frequency alone. Maximum resting pressure, volume at first urge and maximum rectal tolerance were reduced throughout the postoperative period. Radiotherapy, lower anastomosis and defunctioning stoma (but not operative approach) altered manometric parameters postoperatively. Maximum rectal tolerance correlated with incontinence and first urge with stool frequency. The length of the anterior internal anal sphincter decreased postoperatively.

CONCLUSIONS

Incontinence recovers in the first year after anterior resection. Radiotherapy, lower anastomosis, defunctioning stoma and open surgery have a negative influence on bowel function. ARP may be useful if bowel dysfunction persists beyond 12 months.

Comparison of patient-reported quality of life and functional outcomes following laparoscopic and transanal total mesorectal excision of rectal cancer

Purpose

The effect of transanal total mesorectal excision (TaTME) on patients' quality of life and functional outcomes is not fully understood. This study aimed to compare the quality of life and bowel, anorectal, and urogenital functions after laparoscopic and TaTME.

Methods

Laparoscopic or TaTME was performed for 202 propensity score-matched patient pairs with rectal cancer between January 2014 and December 2017 at the National Cancer Center, Korea. The outcomes for all patients were assessed using anorectal manometry, the European Organization for Research and Treatment of Cancer (EORTC) Core Quality of Life Questionnaire (QLQ-C30) and Colorectal Cancer-Specific Quality of Life Questionnaire (QLQ-CR38), low anterior resection syndrome (LARS) score, Fecal Incontinence Severity Index, and International Prostate Symptom Score (IPSS). This retrospective comparative study included patients who completed anorectal manometry and the questionnaires before treatment and at 1 year after surgery.

Results

The EORTC QLQ-C30 and QLQ-CR38 showed comparable outcomes regarding the quality of life in both groups. More patients experienced major LARS in the transanal group at 1 year postoperatively (31.0% vs. 6.8% in the laparoscopic group, P = 0.004). Multivariable analysis revealed no significant difference in the LARS score between the groups at 1 year postoperatively (odds ratio, 2.30; 95% confidence interval, 0.79–6.72; P = 0.127). Significant differences in the IPSS were not noted between the groups.

Conclusion

The quality of life and functional outcomes were comparable between the laparoscopic and transanal approaches; however, our findings suggest a higher rate of LARS after TaTME.

Fecobionics assessment of the effect of position on defecatory efficacy in normal subjects

BACKGROUND

Defecation is a complex process and up to 25% of the population suffer from symptoms of defecatory dysfunction. For functional testing, diagnostics, and therapy of anorectal disorders, it is important to know the optimal defecation position. is The aim of this study was to evaluate defecation pressure patterns in side lying, seated and squatting defecation positions in normal subjects using a simulated stool device called Fecobionics.

METHODS

The Fecobionics expulsion parameters were assessed in an interventional study design conducted from May 29 to December 9 2019. Subjects were invited to participate in the study through advertisement at The Chinese University of Hong Kong. The Fecobionics device consisted of a core containing pressure sensors at the front (caudal end) and rear (cranial end) and a polyester-urethane bag spanning most of the core length which also contained sensors. The Fecobionics bag was distended to 50 ml in the rectum of normal subjects (no present and past symptoms of defecatory disorders, no prior abdominal surgery, medication or chronic diseases). Studies were done in side lying (left lateral recumbent position), seated (hip flexed 90°) and squatting position (hip flexed 25°). Pressure endpoints including the rear-front pressure diagram and defecation indices were compared between positions.

RESULTS

Twelve subjects (6 females/6 males, mean age 26.3 ± 2.6 [19.0-48.0] years) were included and underwent the planned procedures. The resting anal pressure for side lying and seated positions were 33.1 ± 4.1 cmH₂O and 37.1 ± 4.0 cmH₂O (p > 0.3). The anal squeeze pressure for side lying and seated positions were 98.4 ± 6.9 cmH₂O and 142.3 ± 16.4 cmH₂O (p < 0.05). The expulsion duration for the side lying, seated and squatting positions were 108.9 ± 8.3 s, 15.0 ± 2.1 s and 16.1 ± 2.9 s, respectively (p < 0.01 between lying and the two other positions). The maximum evacuation pressure for seated and squatting were 130.1 ± 12.4 cmH2O and 134.0 ± 11.1 cmH₂O (p > 0.5). Rear-front pressure diagrams and distensibility indices demonstrated distinct differences in pressure patterns between the side lying position group and the other positions.

CONCLUSIONS

The delay in expelling the Fecobionics device in the lying position was associated with dyssynergic pressure patterns on the device. Quantitative differences were not found between the seated and squatting position. Trial Registration http://www.clinicaltrials.gov Identifier: NCT03317938.

Clinical outcome and quality of life after gracilis muscle transposition for fistula closure over a 10-year period

PURPOSE

Gracilis muscle transposition (GMT) is an established surgical technique in the treatment of anorectal fistulas and fistulas to the vagina and the urinary system when previous closure options have failed. There is little evidence on the success rate of this procedure in the long term.

METHODS

This is a follow-up study on all patients undergoing GMT over a 10-year period at a tertiary referral center for complex fistulas. Postoperative function and quality of life were evaluated by standardized questionnaires (Wexner score, Fecal Incontinence Quality of Life Score (FIQL), SF-12 and a brief questionnaire designed for this study). Sexual function was evaluated by the Female Sexual Function Index (FSFI) and the International Index of Erectile Function.

RESULTS

Forty-seven gracilis muscle transpositions (GMT) in 46 patients were performed. Most treated patients had (neo-)-rectovaginal fistulas (n = 29). An overall fistula closure was achieved in 34 of 46 patients (74%): in 25 cases primarily by GMT (53%) and in nine patients with persistent or recurrent fistula by additional surgical procedures. A clinically apparent relapse occurred on average 276 days (median: 180 days) after GMT (mean follow-up 73.4 months).

CONCLUSION

GMT in our hands has a primary closure rate of 53%, and after further procedures, this rises to 74%. Fecal continence is impaired in patients having undergone GMT. The overall quality of life in patients after GMT is only slightly impaired, and sexual function is severely impaired in female patients.

Metrics Used to Quantify Fecal Incontinence and Constipation

While fecal incontinence and constipation can be measured through physiological testing, the subjective experience of severity and impact on health-related quality of life lead to both being most effectively captured through patient-reported measures. Patient-reported measures of severity and impact help to determine baseline symptoms, guide clinical decision making, and compare various treatments. Here, we take pause to review the psychometric qualities that make effective instruments, and discuss some of the most commonly used instruments along with the reasons behind their use. In addition, we highlight the benefits of a standardized instrument designed to evaluate the major symptoms of patients presenting with pelvic floor disorders (including fecal incontinence and constipation). Ultimately, we aim to provide guidance in choosing appropriate instruments for clinical and research use.

Urinary and fecal incontinence in patients with advanced ovarian cancer treated with CRS + HIPEC

PURPOSE

The objective of this work was to analyze the long-term prevalence of urinary and fecal incontinence and their impact on quality of life in patients with advanced and recurrent ovarian cancer treated with cytoreductive surgery and hyperthermic intraoperative intraperitoneal chemotherapy (CRS + HIPEC).

METHODS

This cross-sectional study included a series of patients with advanced and recurrent ovarian cancer treated by CRS + HIPEC, with a disease-free period of at least 12 months after the procedure. Urinary incontinence was evaluated using the International Consultation on Incontinence Questionnaire - Short Form (ICIQ-SF), fecal incontinence using the Wexner test and the Fecal Incontinence Quality of Life (FIQL) questionnaire and global quality of life using the Short Form 36 (SF-36) survey.

RESULTS

A total of 64 patients were included in the study, with a median age of 55 years (range 28-78). The urinary incontinence rate was 45% and the fecal incontinence rate was 20%. Up to 14% of the patients presented both types of incontinence. The presence of urinary or fecal incontinence generated a significant negative impact on quality of life in relation to patients without incontinence.

DISCUSSION

Urinary and fecal incontinence is frequent in the follow-up of ovarian cancer patients treated with CRS + HIPEC. Reconsidering the approach to the pelvis without peritoneal metastases in the peritoneum could modify the incidence of these pelvic floor dysfunctions.

The severity of symptoms is insufficient to predict major alterations to quality of life of patients with fecal incontinence or chronic constipation

PURPOSE

Evaluate the impact of fecal incontinence (FI) and chronic constipation (CC) on the quality of life (QoL) in a large population and determine if a threshold of symptom scores was associated with alterations to QoL.

METHODS

A total of 422 outpatients with FI (n = 186), CC (n = 186), and mixed FI-CC (n = 50) referred for anorectal manometry were included prospectively. All patients completed a set of questionnaires to evaluate the severity of FI and CC (respectively Jorge and Wexner and KESS scores) and their impact on QoL (Gastrointestinal Quality of Life Index (GIQLI)).

RESULTS

The study population included 81.8% women. The QoL was altered to the same degree for both FI and CC, with significant more marked impairments in patients with mixed FI-CC (median GIQLI: 91 (71-108) vs. 91 (73-108) vs. 81 (57-97) respectively, p = 0.05). The symptom severity significantly but weekly correlated with the GIQLI score (r² = - 0.454 for FI and r² = - 0.483 for CC, p < 0.001). Thus, the large dispersion of the data flawed the identification of a threshold for symptom severity that could predict major impairment to QoL.

CONCLUSION

The QoL was equally altered for FI and CC. Although the symptom score severity was slightly but significantly associated with alterations to QoL, it was not possible to determine a threshold for symptom scores that predict an alteration to QoL. Therefore, the evaluation of QoL in parallel to the assessment of the symptom score is required to endorse the entire spectrum of the severity of CC or FI.

The relationships between the results of contemporary tests of anorectal structure and sensorimotor function and the severity of fecal incontinence

BACKGROUND

Diagnostic investigations for fecal incontinence (FI) assess the structure and sensorimotor function of the anorectum. Investigations include anorectal manometry, anorectal sensory testing, pudendal nerve terminal motor latencies (PNTML), and endoanal sonography. The severity of FI and results of investigations are often discordant and the rate of symptom resolution following treatment remains <40%. High-resolution anorectal manometry (HRAM) and three-dimensional endoanal ultrasound (3D-US) have been introduced during the last decade. This study aims to assess the strength of relationships between contemporary investigation results and FI severity.

METHODS

Adults presenting for investigation of FI were assessed using the St Mark's FI severity score (SMIS), HRAM, anorectal sensory testing, PNTML, and 3D-US.

KEY RESULTS

246 patients were included. There were significant relationships between the SMIS and HRAM (resting pressure r_s = -0.23, 95% CI = (-0.34, -0.11), P < .001; squeeze pressure (r_s  = -0.26, 95% CI = (-0.37, -0.14), P < .001) and 3D-US (anterior EAS length r_s = -0.22, 95% CI = (-0.34, -0.09), P = .001). The relationships between SMIS and HRAM had a greater effect size in those with urge-predominant symptoms (resting pressure: r_s = -0.40, 95% CI = (-0.57, -0.20), P < .001, squeeze pressure: r_s = -0.34, 95% CI = (-0.52, -0.12), P = .003). Overall, the variance in SMIS accounted for by anorectal investigations was 8.6% (R² = 0.098, adjusted R² = 0.086, P < .001).

CONCLUSIONS AND INFERENCES

Anorectal investigations are not strong predictors of FI severity. These findings may reflect the multifactorial, heterogeneous pathophysiology of FI, the limitations of the SMIS and anorectal investigations, and contributing factors extrinsic to the anorectum.

Physiotherapy for Prevention and Treatment of Fecal Incontinence in Women-Systematic Review of Methods

Fecal incontinence (FI) affects approximately 0.25-6% of the population, both men and women. The most common causes of FI are damage to/weakness of the anal sphincter muscle and/or pelvic floor muscles, as well as neurological changes in the central or peripheral nervous system. The purpose of this study is to report the results of a systematic review of the possibilities and effectiveness of physiotherapy techniques for the prevention and treatment of FI in women. For this purpose, the PubMed, Embase, and Web of Science databases were searched for 2000-2020. A total of 22 publications qualified for detailed analysis. The studies showed that biofeedback (BF), anal sphincter muscle exercises, pelvic floor muscle training (PFMT), and electrostimulation (ES) are effective in relieving FI symptoms, as reflected in the International Continence Society recommendations (BF: level A; PFMT and ES: level B). Research has confirmed that physiotherapy, by improving muscle strength, endurance, and anal sensation, is beneficial in the prevention of FI, both as an independent method of conservative treatment or in pre/post-surgery treatment. Moreover, it can significantly improve the quality of life of patients. In conclusion, physiotherapy (in particular, BF, PFMT, or ES, as effective methods) should be one of the key elements in the comprehensive therapy of patients with FI.

Novel Fecobionics Defecatory Function Testing

INTRODUCTION

Defecation is a complex process that can be easily disturbed. Defecatory disorders may be diagnosed using specialized investigation, including anorectal manometry (ARM) and the balloon expulsion test (BET). Recently, we developed a simulated stool named Fecobionics that integrates several tests and assesses pressures, orientation, and bending during evacuation. The aim was to evaluate the feasibility and performance of Fecobionics for assessing defecatory physiology in normal subjects.

METHODS

Physiological expulsion parameters were assessed in an interventional study design. The 10-cm-long Fecobionics probe contained pressure sensors at the front and rear and inside a bag and 2 motion processor units. The bag was distended in the rectum of 20 presumed normal subjects (15 female/5 male) until urge to defecate. ARM-BET was also performed. Three subjects used +2 minutes to evacuate BET, and 1 subject had a high fecal incontinence score. Therefore, the normal group consisted of 16 subjects (13 female/3 male aged 25-78 years).

RESULTS

All subjects reported that Fecobionics evacuation was similar to normal defecation. Fecobionics expulsion pressure signatures demonstrated 5 phases, reflecting rectal pressure, anal relaxation, and anal passage. Preload-afterload loop diagrams demonstrated clockwise contraction cycles. The expulsion duration for BET and Fecobionics was 16 ± 2 and 23 ± 5 seconds (P > 0.2), respectively. The duration of the Fecobionics and BET expulsions was associated (P < 0.001). The change in bending of Fecobionics during defecation was 40 ± 3°.

DISCUSSION

Fecobionics obtained reliable data under physiological conditions. Agreement was found for comparable variables between ARM-BET and Fecobionics but not for other variables. The study suggests that Fecobionics is safe and effective in evaluation of key defecatory parameters.

Does Implantation of an Artificial Soft Anal Band Provide an Opportunity for Improvement of Biopsychosocial Function in Patients with Severe Fecal Incontinence?

Introduction

Severe fecal incontinence describes a condition of complete loss of control over fundamental physiological functions and loss of abilities to fulfil psychosocial functions by the patients. The last-step procedure, that is, to restore hope for improvement of biopsychosocial functioning and quality of life determined by the patient's health status is implantation of an artificial anal sphincter.

Objective

The study was a comparative analysis of the effect of the employed surgical procedure upon the degree of defecation control and quality of life indices in its behavioral, mental, and social aspects prior to and 3, 6, and 12 months postoperatively. The analysis also included the effect of the patient's individual style of coping with stress and the functional outcome of the procedure.

Material and Methods

The study included a group of 12 patients: 6 females and 6 males, aged from 36 to 60 years of life. The tools consisted of scoring systems that measured symptom intensity (FISI and Jorge and Wexner scale). In assessing the psychosocial functioning, the authors employed the Fecal Incontinence Quality of Life Scale (by Rockwood). The individual mode of coping with the disease was evaluated by using the CISS scale by Endler and Parker.

Conclusions

The analysis of results demonstrated that the procedure of implanting an artificial anal sphincter affected the "continence" (up to 50-60% postoperatively) and led to improvement in psychosocial functioning in all its assessed aspects, i.e., lifestyle, employment of precautionary measures, depression, anxiety, and embarrassment. It was also noted that due to the specific character of the procedure (the necessity to operate an artificial implant), better mean results in assessment of the procedure functionality were achieved by patients presenting the goal-concentrated mode rather than emotions-concentrated mode of coping with the disease. Thus, it seems justified to state that assessment of biopsychological functioning may be a good criterion of the procedure effectiveness.

Quality of life in 1870 patients with constipation and/or fecal incontinence: Constipation should not be underestimated

BACKGROUND

Quality of life is increasingly seen as important, but remains difficult to assess in patients with functional anorectal complaints.

OBJECTIVE

We aimed to quantify quality of life and to analyse the symptomatic descriptors associated with a poor outcome in patients with faecal incontinence (FI) and/or constipation.

METHODS

The characteristics of the patients, data from self-administered questionnaires and from physical examinations were evaluated prospectively for all cases of functional anorectal disease over a period of thirteen years. Functional anorectal disease included faecal incontinence (FI) and/or constipation. Patients with scores in the lowest quartile of the Gastrointestinal Quality of Life Index (GIQLI) were considered to have suffered severe alterations to their quality of life, and were compared with the other patients.

RESULTS

In total, 1870 patients with functional anorectal disease were included (470 with a severely altered quality of life (GIQLI < 70)). Constipation predominated (1212/1870; 65.1%) and severe FI was frequent (761/1870; 40.9%). Severely altered quality of life was significantly associated with constipation (P = 0.0001), urinary urgency and incontinence (P = 0.0001), depression (P = 0.001), diabetes (P = 0.0224), severe FI (P = 0.0001), neurological disease (P = 0.0138) and liquid stools (P = 0.0002) in multivariate analysis.

CONCLUSION

Several treatable factors are associated to an impaired quality of life in patients with functional anorectal disorders. Intervention studies are mandatory (stool consistency and frequency).

Relationships between the results of anorectal investigations and symptom severity in patients with faecal incontinence

PURPOSE

Anorectal dysfunction is the focus of diagnostic investigations for faecal incontinence. However, severity of incontinence and anorectal investigation results can be discordant. The aim of this study was to define the relationships between anorectal investigation results and incontinence severity to determine which measures, if any, were predictive of incontinence severity.

METHODS

Patients presenting for investigation of faecal incontinence completed a symptom questionnaire, anorectal manometry, rectal sensation, pudendal nerve terminal motor latency, and endoanal ultrasound. Bivariate analyses were conducted between the Jorge-Wexner score and investigation results. Subgroup analyses were performed for gender and symptom subtypes (urge, passive, mixed). A multiple regression analysis was performed.

RESULTS

Five hundred and thirty-eight patients were included. There were weak correlations between the Jorge-Wexner score and maximal squeeze pressure [r = - 0.24, 95%CI(- 0.31, - 0.16), p < 0.001], and resting pressure [r = - 0.18, (95%CI(- 0.26, - 0.10), p < 0.001]. In men only, there were significant associations between the Jorge-Wexner score and endoanal sonography [IAS defects: t(113) = - 2.26, p = 0.03, d = 0.58, 95%CI(- 4.38, - 0.29)] and rectal sensation (MTV: r_s = - 0.24, 95%CI(- 0.41, - 0.06), p = 0.01). No substantial differences were observed in the urge/passive/mixed subgroup analyses. Multiple regression analysis included three variables: age (β = 0.02, p = 0.17), maximal resting pressure (β = - 0.01, p = 0.28), and maximal squeeze pressure (β = - 0.01, p < 0.01). The variance in the Jorge-Wexner score accounted for by this model was < 10%, (R² = 0.07, p = < 0.01, adjusted R² = 0.06).

CONCLUSION

Anorectal investigations cannot predict the severity of faecal incontinence. This may be due to limitations of diagnostic modalities, the heterogeneity of anorectal dysfunction in these patients, or contributing factors which are extrinsic to the anorectum.

Initial development and validation of a fecal incontinence-specific quality of life measure

BACKGROUND/PURPOSE

Fecal incontinence is a prevalent pediatric condition with psychosocial impacts on both children and their caregivers. We sought to develop and validate the Cincinnati Fecal Incontinence Scale (CINCY-FIS) as a psychometrically valid measure to assess the quality of life and caregiver impacts of pediatric fecal incontinence.

METHODS

Items were generated through review of previous measures, expert consensus, and pilot testing with feedback from 8 families. Initial study measures were completed by 222 caregivers. Following item reduction, 18 items were subjected to confirmatory factor analysis. Convergent and criterion validity were assessed using correlation. Reliability was established using internal consistency statistics and test-retest reliability at baseline and 2-week follow-up.

RESULTS

A five factor first-order structure with two higher-order factors demonstrated acceptable fit to the data, was consistent with a priori hypotheses, and was more parsimonious than the alternative model. Convergent validity and criterion-related validity were established for all of the CINCY-FIS scales. Reliability was high and consistent across both measurement occasions.

CONCLUSIONS

The CINCY-FIS is a reliable and valid assessment of pediatric fecal incontinence-specific quality of life and parenting stress. The score is highly sensitive to patient changes making it suitable for both clinical and research purposes.

How to establish a successful bowel management programme in children: a tertiary paediatric centre experience

BACKGROUND

Bowel management is a term used to describe a medical approach to the management of faecal incontinence.

AIMS

To present the outcomes of an individualised bowel management programme developed by a tertiary paediatric centre and evaluate contributory factors for successful bowel management in children.

METHODS

A retrospective review of children attending a bowel management clinic in a tertiary centre in Dublin, Ireland, over 5 years (2010-2015). The main outcome measure was the ability to achieve a regular bowel pattern and remain socially clean. Multiple linear regression analyses were used to determine the factors contributing to successful bowel management.

RESULTS

One hundred ninety-two children attended the clinic over 5 years. The median age at commencement of washouts was 7 years. Underlying diagnosis was spina bifida in 50%, imperforate anus in 17.7%, Hirschsprung's disease in 14.6%, idiopathic constipation in 7.8%, and other conditions in 9.9% of patients. Children with spina bifida and Hirschsprung's disease preferred Peristeen washouts, while those with imperforate anus and idiopathic constipation preferred Willis washouts (p < 0.001). Our programme was successful in 93.7% of cases. Regression analysis showed that the underlying condition (p < 0.001), washout medication (p = 0.016), and individuals administering washouts (p < 0.001) contributed to a successful bowel management programme.

CONCLUSION

Treatment protocols should be individualised based on the underlying condition and outcomes. Decision-making must be cognisant of the physical, social, psychological, and developmental needs of the child and family. A partnership approach is advocated, which includes child and parent/carer preferences allowing them to make an informed decision.

Short- and long-term clinical and patient-reported outcomes following laparoscopic ventral mesh rectopexy using biological mesh for pelvic organ prolapse: a prospective cohort study of 224 consecutive patients

AIM

Laparoscopic ventral mesh rectopexy (LVMR) is potentially a safe and effective operation to correct pelvic organ prolapse and to treat obstructive defaecation and solitary rectal ulcer syndrome. This study aimed to evaluate, in a prospective, consecutive cohort of patients, the long-term clinical outcomes following LVMR, patient-reported functional and quality of life outcomes, and urinary and sexual dysfunction.

METHOD

Data on 224 patients who underwent LVMR with Permacol™ biological mesh were collected prospectively from May 2008 to October 2016. Outcome measures were complications, recurrence, mortality, patient satisfaction, patient-reported functional and quality of life outcomes, and urinary and sexual dysfunction. Scores were compared using the two-tailed Wilcoxon signed rank test. P < 0.05 was considered statistically significant.

RESULTS

There was no mortalities associated with LVMR in this series; complications occurred in 10.7% of patients (4.9% early, 5.8% late). Mesh-related morbidity was 0.45% and vaginal suture-related morbidity was 1.33%. Recurrence occurred in 25 patients (11.4%), 5% at 12 months, 10.7% at 5 years. Significant improvement in patient-reported functional outcomes were seen (P < 0.001) for both constipation and faecal incontinence symptoms. Furthermore, significant improvement in quality of life outcomes for patients with constipation, faecal incontinence and prolapse persisted through follow-up (P < 0.001). Patient satisfaction was positive for > 90% of patients during follow-up. Symptoms of stress urinary incontinence, urge incontinence and dyspareunia improved significantly postoperatively (P < 0.001).

CONCLUSION

LVMR using Permacol is associated with low morbidity and mortality, recurrence and, additionally, significantly improved constipation, faecal incontinence and prolapse functional and quality of life outcomes, with associated improvement in urogynaecological symptoms.

Faecal incontinence: a narrative review of clinic-based management for the general gynaecologist

The objective of this article is to provide an informative and narrative review for the general Gynaecologist regarding the pathophysiology and conservative treatments available for faecal incontinence (FI). A PubMed search was performed by library staff and an author using the keywords: anal incontinence, faecal incontinence, accidental bowel leakage, outpatient clinic management of faecal incontinence and defecatory dysfunction. As the social limitations of FI can be devastating and long-term patient satisfaction rates after anal sphincteroplasty remain reportedly-low, the role of clinic-based management of FI has continued to grow. The purpose of this article is to provide the Obstetrician and Gynaecologist with a basic template for screening, evaluation and management of faecal incontinence in the clinical setting.

Safety and feasibility of laparoscopic intersphincteric resection for a lower rectal tumor

The aim of the present study was to evaluate the short-term surgical outcomes of laparoscopic intersphincteric resection (ISR) for a lower rectal tumor in comparison with a case-control series of patients undergoing open ISR. Quality of life factors and anal function were also evaluated. Between July 2008 and April 2013, 103 patients with lower rectal cancer underwent laparoscopic surgery at the Surgical Oncology Department of Gifu University School of Medicine. A total of 25 patients with lower rectal cancer underwent ISR, and 19/25 patients who underwent laparoscopic ISR were compared with the control group of 6 patients who underwent open ISR. The technical feasibility and safety of ISR, and the short- and long-term outcomes following laparoscopic ISR were evaluated. Additional data associated with fecal incontinence conditions of the postoperative patients were evaluated using the Modified Fecal Incontinence Quality of Life scale. There was no recorded perioperative mortality, three complications were observed to occur in three patients and the morbidity rate was 15.8%. The postoperative complications detected included bleeding in one patient and ileus in two patients of the laparoscopic ISR group. The rate of severe complications of grade ≥3a was 15.8% and that of grade ≥3b was 5.3%. In the matched case-control study, blood loss was significantly lower in the laparoscopic ISR group. The median postoperative hospital stay was 14.1 days in the laparoscopic ISR group, which was significantly shorter compared with in the open ISR group (18.7 days). Cancer recurrence was detected in one (5%) patient in a single inguinal lymph node. No significant differences between the ISR and ultra-low anterior resection (ULAR) groups were observed in the maximum resting and maximum squeeze pressures; the outcomes for anal function and fecal incontinence were the same for ISR and ULAR. Thus, laparoscopic ISR for lower rectal cancer may provide a benefit in the early postoperative period without increasing morbidity or mortality.

Long-term results of the Duhamel technique are superior to those of the transanal pullthrough: A study of fecal continence and quality of life

BACKGROUND/PURPOSE

The Duhamel and transanal pull-through (TAPT) techniques have been commonly used for the treatment of children with Hirschsprung disease (HD). However, despite adequate treatment, some patients present with fecal incontinence that severely affects the quality of life (QoL) and lead to psychiatric disorders. The objectives of the present study were to evaluate, through previously adapted questionnaires, the incidence of fecal incontinence and the quality of life (QoL) of children with HD who underwent Duhamel or TAPT techniques. In addition, we compared the incidence of fecal incontinence and QoL indices in these patients with those in healthy children.

MATERIALS/METHODS

The Fecal Continence Index (FCI) questionnaire and the questionnaire for the Assessment of Quality of Life in Children and Adolescents with Fecal Incontinence (AQLCAFI) were used in this study. A series of 41 patients with HD were divided into 2 groups according to the utilized surgical technique: the Duhamel group (20 patients) and the TAPT group (21 patients). The patients were compared with a control group of 59 healthy children.

RESULTS

In the control group, 25 (42.4%) children had good continence and 34 (57.6%) had normal continence. In contrast, among patients with HD, 4 (9.8%) had poor fecal continence, 11 (26.8%) had fair continence, 18 (43.9%) had good continence, and 8 (19.5%) had normal continence. The QoL of children with HD was globally impaired in all domains of the AQLCAFI as well as in the FCI, when compared with the QoL of healthy children (P=0.001). The comparison between children who underwent surgery with the Duhamel technique and those who underwent surgery with TAPT technique showed similar outcomes according to the FCI. However, the results were inferior in patients who underwent TAPT technique according to the AQLCAFI questionnaire (P=0.003), lifestyle (P=0.006), behavior (P=0.01), depression (P=0.01), and embarrassment (P=0.003).

CONCLUSION

The QoL and the FCI were impaired in patients who underwent surgery for correction of HD compared with healthy children; however, the impairment in QoL was greater in patients who underwent TAPT technique.

Pelvic Floor Disorders 6 Months after Attempted Operative Vaginal Delivery According to the Fetal Head Station: A Prospective Cohort Study

Objective

To evaluate the effect of the fetal head station at attempted operative vaginal delivery (aOVD), and specifically midpelvic or low aOVD, on urinary incontinence (UI), anal incontinence (AI), and perineal pain at 6 months.

Design

Prospective cohort study.

Setting

1941 women with singleton term fetuses in vertex presentation with midpelvic or low aOVD between 2008 and 2013 in a tertiary care university hospital.

Methods

Symptoms of urinary incontinence (UI) using the Bristol Female Lower Urinary Tract Symptoms questionnaire, and symptoms of anal incontinence (AI) severity using Fecal Incontinence Severity Index (FISI) were assessed 6 months after aOVD. We measured the association between midpelvic or low aOVD and symptoms of UI, AI, and perineal pain at 6 months using multiple regression and adjusting for demographics, and risk factors of UI and AI, with adjusted odds ratios (aORs) and 95% confidence intervals (95% CI).

Results

The study included 907 women (46.7%) who responded to the questionnaire; 18.4% (167/907) had midpelvic aOVD, and 81.6% (740/907) low; and none of women with symptoms of UI (26.6%, and 22.4%, respectively; p = 0.31), AI (15.9%, and 21.8%; p = 0.09), the FISI score, and perineal pain (17.2%, and 12.7%; p = 0.14) differed significantly between groups. The same was true for stress, urge, and mixed-type UI, severe UI and difficulty voiding. Compared with low pelvic aOVD, the aORs for symptoms of UI in midpelvic aOVD were 0.70 (0.46–1.05) and AI 1.42 (0.85–2.39). Third- and fourth-degree tears were a major risk factor of symptoms of UI (aOR 3.08, 95% CI 1.35–7.00) and AI (aOR 3.47, 95% CI 1.43–8.39).

Conclusion

Neither symptoms of urinary nor anal incontinence differed at 6 months among women who had midpelvic and low pelvic aOVD. These findings are reassuring and need further studies at long-term to confirm these short-term data.

Efficacy of anorectal biofeedback in scleroderma patients with fecal incontinence: a case-control study

OBJECTIVE

To determine whether anorectal biofeedback therapy can improve the symptoms of fecal incontinence (FI) in patients with scleroderma when compared to patients with functional FI, and also whether there is any effect on anorectal physiology or quality of life (QOL). FI in patients with scleroderma is highly prevalent and is associated with significant loss of QOL. Biofeedback has been proven to be an effective treatment for functional FI, but there are no data to support its use in scleroderma.

MATERIALS AND METHODS

13 consecutive female patients (median age 59, IQR 47-65 years) with scleroderma, and 26 age- and parity-matched female patients with functional FI (disease controls, 2:1), underwent biofeedback therapy for management of FI. Fecal incontinence severity index (FISI), anorectal physiology, feeling of control and QOL were collected before and after 6 weeks of biofeedback therapy, with additional scoring repeated at 6-month follow-up.

RESULTS

After biofeedback treatment FISI, feeling of control and QOL significantly improved in both groups (p < 0.005). There was no difference in the degree in improvement in physiology, FISI or QOL between scleroderma patients and functional FI patients. Long-term improvement in FISI and control were seen in both groups and for QOL only in the scleroderma cohort (p < 0.05).

CONCLUSIONS

Patients with scleroderma benefit from biofeedback therapy to the same extent as that achieved in patients with functional FI. There are significant improvements in symptoms, physiology and QOL. Biofeedback is an effective, low-risk treatment option in this patient group.

Vagus Nerve Stimulation Alters Phase Synchrony of the Anterior Cingulate Cortex and Facilitates Decision Making in Rats

Vagus nerve stimulation (VNS) can enhance memory and cognitive functions in both rats and humans. Studies have shown that VNS influenced decision-making in epileptic patients. However, the sites of action involved in the cognitive-enhancement are poorly understood. By employing a conscious rat model equipped with vagus nerve cuff electrode, we assess the role of chronic VNS on decision-making in rat gambling task (RGT). Simultaneous multichannel-recordings offer an ideal setup to test the hypothesis that VNS may induce alterations of in both spike-field-coherence and synchronization of theta oscillations across brain areas in the anterior cingulate cortex (ACC) and basolateral amygdala (BLA). Daily VNS, administered immediately following training sessions of RGT, caused an increase in 'good decision-maker' rats. Neural spikes in the ACC became synchronized with the ongoing theta oscillations of local field potential (LFP) in BLA following VNS. Moreover, cross-correlation analysis revealed synchronization between the ACC and BLA. Our results provide specific evidence that VNS facilitates decision-making and unveils several important roles for VNS in regulating LFP and spike phases, as well as enhancing spike-phase coherence between key brain areas involved in cognitive performance. These data may serve to provide fundamental notions regarding neurophysiological biomarkers for therapeutic VNS in cognitive impairment.

Long-term evaluation of fecal continence and quality of life in patients operated for anorectal malformations

Summary Introduction: Patients operated for correction of anorectal malformations (ARM) can develop fecal incontinence, constipation, and soiling, with loss in quality of life. Objective: To evaluate, through the use of questionnaires, fecal continence, and quality of life of children in the late postoperative follow-up of ARM correction, both high and low. In addition, the levels of fecal continence and quality of life were compared with those of a control group. Method: A Fecal Continence Index Questionnaire (ICF) and a Questionnaire for Assessment of Quality of Life Related to Fecal Continence in Children and Adolescents (QQVCFCA) were administered to 63 patients with ARM, aged from 7 to 19 years, whose surgical treatment had been completed for at least 6 months. The patients were compared to a control group of 59 children. Results: In the control group, 25 (42.4%) patients had good continence and 34 (57.6%), normal continence. We found that the quality of life in children with ARM is compromised globally, in all areas and in the ICF questionnaire, compared to controls (p<0.001). There was no difference between patients with high and low defects. Thirty-two (50.8%) patients had other associated anomalies. Conclusion: In patients operated for ARM correction, quality of life and ICF were compromised, and there was no difference between patients with high-type and low-type of the disease. In about half the cases there are other associated malformations.

Fecal incontinence: A review of current treatment options

Fecal incontinence affects patients of all sexes, races, and ethnicities; however, those affected often are afraid or too embarrassed to ask for help. Attention to risk factors and directed physical examinations can help healthcare providers diagnose and formulate treatment plans. Numerous diagnostic tests are available. Diligent follow-up is needed to direct patients to second-line therapies such as sacral nerve stimulation or surgical procedures.

Critical analysis of fecal incontinence scores

INTRODUCTION

Objectively evaluating the lack of bowel control (fecal incontinence) continues to be a challenge. Many have attempted to measure the severity of fecal incontinence and to evaluate its impact on the quality of life by developing standardized scoring systems. Some of these systems have been validated but none have achieved widespread use and all have limitations in evaluating pediatric patients.

METHODS

A review of the literature was performed looking for validated scoring systems of fecal incontinence that are currently used for either adult or pediatric patients. The identified scoring systems were then critically analyzed and their applicability for managing fecally incontinent children considered.

RESULTS

Thirteen of the most frequently used fecal incontinence scoring systems were selected (6 for adults and 7 for children). Quality of life questionnaires were excluded not only because of their length and complexity, but mostly because they do not accurately reflect a measurement of bowel control. Our analysis revealed that all pediatric scoring systems require some degree of interpretation as they included at least one subjective parameter. These unverifiable subjective parameters were: "sensation of rectal fullness", "sphincter squeeze", and "anal shape". Equally problematic, the pediatric systems frequently focused on factors unrelated to fecal continence such as "frequency of bowel movements", "rectal prolapse", "abdominal pain", "blood in the stool", "leakage of urine", "diarrhea", and "constipation". The most objective system found from our review is the Krickenbeck system, which focuses upon two objective factors. Those two factors are the absence of voluntary bowel movements and the presence of soiling in the underwear. The major weakness of the Krickenbeck system is that it does not allow for reassessment after medical or surgical interventions. In this paper, we propose a modification of the Krickenbeck system that allows for such an assessment to be applied to those patients who are able to achieve voluntary bowel movements with the aid of laxatives or constipating agents.

CONCLUSIONS

Most scoring systems are flawed because they invite bias and interpretation due to their subjective nature, while systems focused on measuring quality of life do not address the fundamental issue of bowel control. The Krickenbeck score seems to be the most applicable and objective method of evaluating bowel control in pediatric patients that may be more useful when modified to assess patients after medical intervention.

[Validation of questionnaires to assess quality of life related to fecal incontinence in children with anorectal malformations and Hirschsprung's disease]

Objective:

Surgical treatment of anorectal malformations (ARMs) and Hirschsprung's disease (HD) leads to alterations in bowel habits and fecal incontinence, with consequent quality of life impairment. The objectives were to create and validate a Questionnaire for the Fecal Incontinence Index (FII) based on the Holschneider score, as well as a Questionnaire for the Assessment of Quality of Life Related to Fecal Incontinence in Children and Adolescents (QQVCFCA), based on the Fecal Incontinence Quality of Life.

Methods:

The questionnaires were applied to 71 children submitted to surgical procedure, in two stages. Validity was tested by comparing the QQVCFCA and a generic quality of life questionnaire (SF-36), and between QQVCFCA and the FII. A group of 59 normal children was used as control.

Results:

At two stages, 45.0% (32/71) and 42.8% (21/49) of the patients had fecal incontinence. It was observed that the QQVCFCA showed a significant correlation with the SF-36 and FII (Pearson's correlation 0.57), showing that the quality of life is directly proportional to improvement in fecal incontinence. Quality of life in patients with fecal incontinence is still globally impaired, when compared with control subjects (p<0.05, Student's t-test). There were also significant differences between the results of children with ARMs and children with HD.

Conclusions:

QQVCFCA and FII are useful tools to assess the quality of life and fecal incontinence in these groups of children. Children with ARMs submitted to surgical procedure and HD have similar quality of life impairment.

Validation of a bowel dysfunction instrument for adolescents with spina bifida

INTRODUCTION

Existing survey instruments for bowel dysfunction in the pediatric population are either parent-reported or focus on non-neurogenic bowel dysfunction.

OBJECTIVE

The purpose of this study was to develop and validate an adolescent-reported survey to assess the severity of bowel dysfunction in spina bifida patients and examine its impact on quality of life (QOL).

STUDY DESIGN

We performed a cross-sectional study of patients in our Myelodysplasia Program, aged 11-17 years, with a history of constipation and/or fecal incontinence (FI) from November 2010 to June 2013. Control patients, aged 11-17 years, were recruited from the stone clinic. Exclusion criteria were lack of English fluency, insufficient reading skills, or an incontinent fecal diversion. A 29-item version of the Adolescent Fecal Incontinence and Constipation Symptom Index (A-FICSI) was developed with five domains (Figure). Test re-test reliability and correlation with the total global health-related QOL score from the Parkin survey were measured using the Pearson correlation coefficient. A factor analysis model with four-fold correlations was tested.

RESULTS

Of the 65 study-eligible individuals approached, 25 (11 boys) completed the A-FICSI (median age 12.6 years, IQR 11.8-14.7 years) and 17 completed another survey on urinary incontinence (64.6% response rate). Twenty-one control patients with nephrolithiasis completed the A-FICSI. Nine of the 25 completed a second administration of the survey. The mean correlation between repeated administrations of the survey was r = 0.43. There was a significant negative correlation between severity of constipation (r = -0.299, p < 0.05) and severity of FI (r = -0.316, p < 0.05) with the total Parkin QOL score. The Comparative Fit Index (CFI) was 0.864. Most items loaded significantly on their respective factors. Between-factor correlations were all significant (>0.30) in the predicted direction. Unstandardized residuals were 8.7% (95% CI 6.4-10.9%). Item reduction was performed on the 29-item instrument based on results of the factor analysis. The finalized instrument contained 21 items.

DISCUSSION

This is the first adolescent-reported bowel dysfunction instrument to undergo formal psychometric assessment in the spina bifida population. The instrument demonstrated adequate reliability and the five-factor structure fit the data well. This study highlights the negative impact of bowel dysfunction on the QOL of spina bifida patients. It is limited by the moderate sample size that is a common issue in relatively rare diseases.

CONCLUSION

The A-FICSI possesses desirable psychometric properties for the measurement of bowel dysfunction in the spina bifida population.

Efficacy and quality of life after transcutaneous posterior tibial neuromodulation for faecal incontinence

AIM

The aim of this study was to evaluate the efficacy of transcutaneous neuromodulation of the posterior tibial nerve for faecal incontinence and to assess quality of life after the procedure.

METHOD

A prospective non-randomized cohort study was conducted in a tertiary centre from September 2010 to May 2013. All patients with faecal incontinence who met the inclusion criteria were included and were treated as outpatients during a 3-month period by unilateral neuromodulation of the posterior tibial nerve. The patients were followed 3-monthly for 1 year. Severity scales, a bowel diary and quality of life scales were evaluated prospectively before and after treatment.

RESULTS

Twenty-seven patients of median age 67 (interquartile range 60-69) years and a male to female ratio of 1/6 were included. Faecal incontinence was for solid stools in 48.1% of patients with urgency in 55.6%. About one-third (34.6%) had a sphincter defect on ultrasound and reduction of anal canal pressure in 85.2%. There was a significant improvement in episodes of incontinence on the Wexner score and visual analogue scale assessment and a decrease in the number of episodes of incontinence per unit time. The Fecal Incontinence Quality of Life score was improved at the end of the follow-up. No adverse effects were observed. The cost of the treatment was €135 per patient.

CONCLUSION

Transcutaneous posterior tibial nerve neuromodulation provides good treatment for faecal incontinence in terms of efficacy and quality of life.
