ANZ J Surg 2023; 93:1253-1256. [PMID: 36484354 DOI: 10.1111/ans.18200] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/27/2022] [Revised: 11/06/2022] [Accepted: 11/29/2022] [Indexed: 11/30/2023]
Abstract
BACKGROUND Rectal intussusception is often observed in patients with faecal incontinence and obstructed defaecation. The aim of this study is to assess if pelvic floor training improves faecal incontinence and obstructed defaecation in patients with rectal intussusception. METHODS Case notes of all patients referred to Bankstown Hospital Pelvic Floor Clinic between 2013 and 2018 for the management of faecal incontinence and obstructed defaecation and rectal intussusception were retrospectively reviewed using a prospectively maintained database. St Mark's faecal incontinence and Cleveland clinic constipation scores were obtained from patients before and after they underwent pelvic floor training. RESULTS One hundred and thirty-one patients underwent pelvic floor training at Bankstown Hospital Pelvic Floor Clinic between 2013 and 2018. Sixty-one patients had rectal intussusception (22 low-grade and 39 high-grade). Median St Marks score improved following pelvic floor training from 8 to 1 (P < 0.001). Median Cleveland Clinic constipation score improved from 8 to 5 (P < 0.001). In patients with low grade rectal intussusception, pelvic floor training improved median St Mark's score from 3 to 0 (P = 0.003), whereas Cleveland Clinic constipation score improved from 9 to 7 (P < 0.001). In patients with high-grade rectal intussusception, pelvic floor training improved median St Mark's score from 9 to 2 (P < 0.001), whereas median Cleveland Clinic constipation score improved from 8 to 4 (P < 0.001). CONCLUSION Pelvic floor training without biofeedback therapy improves faecal incontinence and obstructed defaecation. Improvement in symptoms is unrelated to rectal intussusception observed on proctography or at examination under anaesthesia in these patients.

Nurse- and Pelvic Floor Physical Therapist-Led Bowel Training in Patients With Fecal Incontinence in a Tertiary Care Center. Gastroenterol Nurs 2021; 44:39-46. [PMID: 33538522 DOI: 10.1097/sga.0000000000000498] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/02/2019] [Accepted: 10/07/2019] [Indexed: 11/25/2022] Open
Abstract
Little is known about nurse- and pelvic floor physical therapist-led bowel training in fecal incontinence after previous conservative management has been deemed unsatisfactory. The objective of this study was to evaluate combined nurse- and physical therapist-led bowel training sessions in a tertiary care center. This was a prospective, cross-sectional study. All patients with fecal incontinence between 2015 and 2016 with and without previous conservative management were included. Combined conservative treatment was defined as the use of stool-bulking agents (psyllium fibers) with or without antidiarrheal medication (loperamide) in combination with biofeedback or pelvic floor muscle training. Questionnaires regarding fecal incontinence (Vaizey incontinence score) and quality of life (Short Form Health Survey-36) were used. A decrease in the Vaizey incontinence score of 5 or more points was deemed to be clinically significant. Vaizey incontinence scores in all 50 patients decreased from 14.7 (SD = 4.5) to 9.9 (SD = 4.8) at follow-up (p < .001). Forty percent of patients reported an improvement in their Vaizey incontinence score (change of 5 or more points). Improvement was noted in those with and without previous treatment. Quality of life improved significantly. The limitation of the study includes lack of a standardized treatment protocol. Fecal incontinence reduced after nurse- and physical therapist-led bowel training sessions in patients with and without previous treatment, increasing their quality of life.

Abstract
Purpose Radiotherapy to the pelvis and especially the anal sphincters can result in long-term faecal incontinence. The aim of this study was to assess the effectiveness of biofeedback anal strengthening exercises in radiotherapy-related faecal incontinence. Methods A retrospective cohort study was performed on seven patients with radiotherapy-related faecal incontinence. Education and biofeedback based anal strengthening exercises were provided. Baseline and follow-up measurements were performed assessing anal sphincter fatigue time, resting, squeeze, and cough pressure. Continence scores and quality of life measures were assessed. Patients were followed up at five months. Results The radiotherapy target varied between prostate, uterus, and rectum. Four of the seven patients were female. Pescatori (0-10) and St Mark’s (0-10) continence scores had a median improvement of 2 (range 0-5) and 1 (range 0-8) respectively. Self-completed patient continence scores (0-10mm) had a median improvement of 2mm (1-6mm). Anal fatigue time measurements (Isotonic Fatigue Time (seconds) and Isometric Fatigue Time (Cycles)) showed a median improvement of three seconds (-4 - 36 seconds) and three seconds (-1 - 6 seconds), respectively. Resting Pressure (mmHg), Squeeze Pressure (mmHg) and Cough Pressure (mmHg) showed median improvement of 10mmHg (-10-21mmHg), 15mmHg (-16 - 100mmHg) and 21mmHg (-3 - 53mmHg), respectively. Patient-defined quality of life (QOL) measures showed a median change of 0.2 (range 0-0.5). Conclusion Patients in this pilot study with radiotherapy-related faecal incontinence had improved anal pressure metrics, continence, and QOL following biofeedback based anal strengthening exercises. These early results suggest a benefit for anal strengthening in patients undergoing pelvic radiotherapy.

Postoperative Functional Management Contributes to Anal Functional Recovery in Patients With Low Rectal Cancer After Robotic Total Intersphincteric Resection. Front Oncol 2020; 10:1373. [PMID: 32974135 PMCID: PMC7471719 DOI: 10.3389/fonc.2020.01373] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/10/2020] [Accepted: 06/30/2020] [Indexed: 12/13/2022] Open
Abstract
Purpose: To evaluate the effectiveness of the comprehensive post-operative management including low-frequency endo-anal electrical stimulation and daily suppository usage on post-operative anal functional recovery for low rectal cancer patients who underwent robotic total intersphincteric resection (ISR). Methods: A retrospective analysis was performed on 42 low rectal cancer patients who underwent robotic total ISR, of which 23 patients received comprehensive post-operative management, including biofeedback low-frequency endo-anal electrical stimulation and daily suppository usage (management group). Wexner score and anorectal manometric values, including resting pressure (RP), maximum squeeze pressure (MSP), initial perceived volume (IPV), and maximum tolerated volume (MTV), were assessed and compared. Results: A total of 42 low rectal cancer patients were included in our study. The RP at 6 months after ISR (40.95 ± 6.95 mmHg vs. 33.29 ± 5.40 mmHg, p = 0.002) and MSP at 3 and 6 months after ISR (72.05 ± 10.16 mmHg vs. 69.05 ± 8.67 mmHg, p = 0.031; 91.57 ± 15.47 mmHg vs. 84.05 ± 12.94 mmHg, p = 0.039, respectively) were significantly higher in the management group. The median IPV at 1 and 3 months after ISR (17.81 ± 3.61 ml vs. 15.43 ± 5.08 ml, p = 0.038; 20.19 ± 4.35 ml vs. 17.67 ± 5.16 ml, p = 0.044, respectively) and MTV at 3 months after ISR (83.71 ± 5.44 ml vs. 76.10 ± 8.42 ml, p = 0.012) were significantly higher in the management group. Wexner scores at 1 and 3 months after closure of stoma (COS) in the management group were significantly lower (11.3 ± 2.9 vs. 13.4 ± 3.0, p = 0.041; 8.9 ± 2.0 vs. 10.6 ± 2.4, p = 0.036, respectively). Conclusions: Comprehensive post-operative management could accelerate the recovery of sphincteric function and anal sensitivity after robotic total ISR and could also contribute to treatment of fecal incontinence followed by COS.

Abstract
PURPOSE OF REVIEW To review the epidemiology, pathogenesis, clinical features, and management of primary constipation and fecal incontinence in the elderly. RECENT FINDINGS Among elderly people, 6.5%, 1.7%, and 1.1% have functional constipation, constipation-predominant IBS, and opioid-induced constipation. In elderly people, the number of colonic enteric neurons and smooth muscle functions is preserved; decreased cholinergic function with unopposed nitrergic relaxation may explain colonic motor dysfunction. Less physical activity or dietary fiber intake and postmenopausal hormonal therapy are risk factors for fecal incontinence in elderly people. Two thirds of patients with fecal incontinence respond to biofeedback therapy. Used in combination, loperamide and biofeedback therapy are more effective than placebo, education, and biofeedback therapy. Vaginal or anal insert devices are another option. In the elderly, constipation and fecal incontinence are common and often distressing symptoms that can often be managed by addressing bowel disturbances. Selected diagnostic tests, prescription medications, and, infrequently, surgical options should be considered when necessary.

Abstract
BACKGROUND Fecal incontinence is a disabling condition affecting up to 20% of women. OBJECTIVE We investigated fecal incontinence assessment in both inflammatory bowel disease and non-inflammatory bowel disease patients to propose a diagnostic approach for inflammatory bowel disease trials. METHODS We searched on Pubmed, Embase and Cochrane Library for all studies on adult inflammatory bowel disease and non-inflammatory bowel disease patients reporting data on fecal incontinence assessment from January 2009 to December 2019. RESULTS In total, 328 studies were included; 306 studies enrolled non-inflammatory bowel disease patients and 22 studies enrolled inflammatory bowel disease patients. In non-inflammatory bowel disease trials the most used tools were the Wexner score, fecal incontinence quality of life questionnaire, Vaizey score and fecal incontinence severity index (in 187, 91, 62 and 33 studies). Anal manometry was adopted in 41.2% and endoanal ultrasonography in 34.0% of the studies. In 142 studies (46.4%) fecal incontinence evaluation was performed with a single instrument, while in 64 (20.9%) and 100 (32.7%) studies two or more instruments were used. In inflammatory bowel disease studies the Wexner score, Vaizey score and inflammatory bowel disease quality of life questionnaire were the most commonly adopted tools (in five (22.7%), five (22.7%) and four (18.2%) studies). Anal manometry and endoanal ultrasonography were performed in 45.4% and 18.2% of the studies. CONCLUSION Based on prior validation and experience, we propose to use the Wexner score as the first step for fecal incontinence assessment in inflammatory bowel disease trials. Anal manometry and/or endoanal ultrasonography should be taken into account in the case of positive questionnaires.

Abstract
AIM Secondary sphincter repair has been the conventional management of anal incontinence (AI) when a structural defect in the sphincter is recognized. However, disappointing long-term results have contributed to a tendency towards an increasing use of alternative treatment methods. This study aimed to assess the long-term functional outcomes following a secondary sphincter repair in women with AI after obstetric sphincter injury. METHOD This is a questionnaire study of women who underwent a secondary sphincter repair in Denmark between January 1990 and December 2005. Patients were identified through the Danish National Patient Registry. Functional outcomes were assessed by a self-administered questionnaire in 2010 and 2018. Primary outcomes were Wexner and St. Mark's scores. Impact on quality of life was assessed using the Fecal Incontinence Quality of Life Scale. RESULTS Functional outcome was assessed in 370 women in 2010 and 255 women in 2018. At 18.3 [interquartile range (IQR 15.0-22.0)] years of follow-up, the mean ± SD Wexner score was 8.8 ± 4.8 and the mean St. Mark's score was 11.7 ± 5.0. Flatus incontinence was the most frequent symptom, reported by 97%. Incontinence for liquid and solid stools was reported by 75% and 54%, respectively. There were no significant changes in incontinence frequencies over time. Women with a Wexner score of ≥ 9 had a significantly lower quality of life score in all domains than did women with a Wexner score of < 9 (P < 0.001). CONCLUSION At long-term follow-up, few patients are fully continent following a secondary sphincter repair. However, it appears that the functional results remain stable at very long-term follow-up.

Abstract
BACKGROUND & AIMS Pelvic floor muscle training (PFMT) in combination with conservative treatment is recommended as first-line treatment for patients with fecal incontinence, although its efficacy is unclear. We investigated whether supervised PFMT in combination with conservative treatment is superior to attention-control massage treatment and conservative treatment in adults with fecal incontinence. METHODS We performed a randomized, controlled, superiority trial of patients with fecal incontinence at a tertiary care center at a public hospital in Denmark. Ninety-eight adults with fecal incontinence were randomly assigned to groups that received supervised PFMT and biofeedback plus conservative treatment or attention-control treatment plus conservative treatment. The primary outcome was rating of symptom changes, after 16 weeks, based on scores from the Patient Global Impression of Improvement scale. Secondary outcomes were changes in the Vaizey incontinence score (Vaizey Score), Fecal Incontinence Severity Index, and Fecal Incontinence Quality of Life Scale. RESULTS In the intention-to-treat analysis, participants in the PFMT group were significantly more likely to report improvement in incontinence symptoms based on Patient Global Impression of Improvement scale scores (unadjusted odds ratio, 5.16; 95% CI, 2.18-12.19; P = .0002). The PFMT group had a larger reduction in the mean Vaizey Score (reduction, -1.83 points; 95% CI, -3.57 to -0.08; P = .04). There were no significant differences in condition-specific quality of life. In the per-protocol analyses, the superiority of PFMT was increased. No adverse events were reported. CONCLUSIONS This randomized controlled trial of adults with fecal incontinence provides support for a superior effect of supervised PFMT in combination with conservative treatment compared with attention-control massage treatment and conservative treatment. We found that participants who received supervised PFMT had 5-fold higher odds of reporting improvements in fecal incontinence symptoms and had a larger mean reduction of incontinence severity based on the Vaizey Score compared with attention control massage treatment.

Abstract
BACKGROUND Biofeedback is an effective method of treatment for fecal incontinence but there is controversy regarding factors that may be correlated with its effectiveness. OBJECTIVE To evaluate the efficacy of biofeedback in the treatment of fecal incontinence, identifying the predictive factors for unsuccessful treatment. METHODS Consecutive female patients who had fecal incontinence and were treated with a full course of biofeedback were screened. The symptoms were evaluated using Cleveland Clinic incontinence (CCF) score before and six months after the completion of therapy. Patients had a satisfactory clinical response to biofeedback if the CCF score had decreased by more than 50% at six months (GI) and an unsatisfactory response if the CCF score did not decrease or if the score decreased by <50% (GII). The groups were compared with regard to age, score, anal resting and squeeze pressures and sustained squeeze pressure by manometry, history of vaginal delivery, number of vaginal deliveries, menopause, hysterectomy, and previous anorectal surgery. RESULTS Of 124 women were included, 70 (56%) in GI and 54 (44%) in GII. The median CCF score decreased significantly from 10 to 5 (P=0.00). FI scores were higher in GII. Patients from GII had more previous vaginal deliveries and previous surgeries. The mean sustained squeeze pressure was higher in GI. Patients from GI and GII had similar ages, number of vaginal deliveries, menopause, hysterectomy, anal pressures, and sphincter defects. The median sustained squeeze pressure increased significantly before and after biofeedback in GI. CONCLUSION Biofeedback therapy shows effective treatment with 50% reductions in FI score in half of patients. Factors associated with unsuccessful outcome include FI score ≥10, previous vaginal delivery, previous anorectal and/or colorectal surgery, and reduced mean sustained squeeze pressure.
