Botulinum-toxin-A injection following conservative management in patients with dyssynergic defaecation only improves symptoms in the short term: a retrospective study

Objective: Dyssynergic defaecation (DD) is an important cause of chronic constipation. In patients where conservative treatments fail, injections of botulinum toxin A (BTX-A) into the puborectalis and anal sphincter muscles can be effective. Complications of this procedure are reported to be rare and generally mild. This study aimed to identify the complication rates and short- to medium-term success rates of BTX-A injections as a treatment for DD. Methods: A retrospective review was conducted on patients diagnosed with DD who had undergone BTX-A injections at a functional colorectal unit. Patient demographics, manometric assessment, conservative management, and injection technique were collected through a chart review. Subjective patient reports and comparison of pre- and postprocedure symptom scores were used to determine efficacy. Results: The 21 patients included (24 procedures, with 3 patients receiving BTX-A on two separate occasions) all received stool modification and dietary advice, and 20 patients underwent pelvic floor physiotherapy, averaging 8 sessions. The injections were universally applied under general anesthetic, primarily targeting the anal sphincter and/or puborectalis muscles. There were 6 reports of faecal urge/incontinence, with all but one being resolved within weeks. The BTX-A injection was subjectively reported as beneficial in 19 cases, averaging 4.7 months (range 1-32) of improvement. Only 2 were sustained beyond 12 months. Despite overall improvements in symptom scores from pre- to postprocedure, none were statistically significant. Conclusion: Following a course of conservative management, the BTX-A injection appears to be a safe treatment for DD, but only has short term efficacy. (AU)

Long-term outcomes of total colectomy for severe constipation.

AIM: Surgery for constipation is usually reserved for patients with severe and refractory symptoms because of concerns about perioperative morbidity and unpredictable functional outcomes. The aim of this paper is to identify the long-term outcomes of patients who have undergone total colectomy and ileorectal anastomosis for severe constipation. METHOD: Patients who had undergone a total colectomy and ileorectal anastomosis for severe constipation were identified from a prospectively maintained database and sent a postal survey assessing functional symptoms, patient satisfaction and the impact of symptoms on quality of life. Information regarding the surgery, perioperative complications and hospitalizations were also collected. Functional outcomes of the surgery were evaluated with the Gastrointestinal Quality of Life Index, St Marks incontinence score, Wexner continence score, obstructed defaecation syndrome score and Cleveland Clinic constipation score. RESULTS: Seventy-one questionnaires were posted and 32 (45%) patients responded. The mean time since surgery was 15.3 years (range 2.9-30.4 years) Most patients were happy with the surgery. Ongoing symptoms were common, the most frequent of these were abdominal pain, experienced by 23 patients (71.9%), and faecal incontinence, experienced by 17 patients (53%). Fourteen patients (43.8%) required subsequent hospital admission due to bowel obstruction and eight patients (25%%) had subsequent surgery for adhesions. There was an association between patient quality of life and subsequent surgeries. CONCLUSION: Most patients were happy and viewed their life as improved following total colectomy for severe constipation. This is despite a high rate of ongoing functional symptoms.

The effect of a sexual abuse history on symptoms and anorectal physiology findings in patients presenting to a colorectal pelvic floor service.

BACKGROUND: Studies report that 12%-23% of patients with functional anorectal disorders have a history of sexual abuse (SA). This article aims to assess whether there is a difference in symptom severity, quality of life or anorectal physiology findings in female patients presenting to a colorectal pelvic floor service with and without a history of sexual abuse. METHODS: A retrospective analysis of all female patients attending a single tertiary pelvic floor unit for faecal incontinence or constipation between 2017 and 2019 was performed. Patients were divided into two groups depending on the presence or absence of a volunteered history of sexual abuse. Validated quality of life and symptom severity scores, along with anorectal physiology studies were analysed and compared between the two groups. RESULTS: There were 148 patients included in the study period and 17% reported a history of SA. There was no statistically significant difference in symptom severity, quality of life scores or anorectal physiology studies between those with and without a history of SA. CONCLUSION: In female patients seeking management for defaecatory symptoms, those who have reported a history of SA did not demonstrate any significant difference in symptom severity, quality of life or physiological measures when compared to those without a history of SA.

Colonoscopic findings in patients with pelvic floor dysfunction.

BACKGROUNDY: Colonoscopy is often performed in the initial workup of pelvic floor dysfunction, even in the absence of red flag symptoms. Current guidelines suggest colonoscopy is only required in the presence of rectal bleeding, diarrhoea or change in bowel habit. The aim of this study was to evaluate the prevalence of significant pathology found at colonoscopy in patients with pelvic floor dysfunction. METHODS: Retrospective chart review was performed on all patients presenting to a functional colorectal outpatient clinic between May 2018 and August 2019. Information was collected on presenting symptoms, whether colonoscopy had been performed within 5 years, quality of bowel preparation, withdrawal time, number of polyps detected, histology, presence of diverticular disease, colorectal malignancy, inflammatory bowel disease, solitary rectal ulcer or rectal prolapse. RESULTS: There were 260 patients seen within the study period, of which 67% had undergone recent colonoscopy within the last 5 years. The mean age was 53 and 219 (84%) patients were female. Average withdrawal time was 13 min. Polyps were found in 48.7% and adenomas in 32.4% of all colonoscopies. The adenoma detection rate was 32.7%. None of the colonoscopies found evidence of malignancy. A new diagnosis of inflammatory bowel disease was discovered in two patients. CONCLUSION: There was low rates of serious pathology such as malignancy or inflammatory bowel disease in patients referred to a functional clinic. However, colonoscopy is still useful in workup of pelvic floor dysfunction, as many patients have erratic bowel habits or vague symptoms, and will have adenomas found.

The effect of transvaginal prolapse surgery on anorectal function

Objective: Pelvic floor dysfunction can manifest as a spectrum including anorectal dysfunction, vaginal prolapse, and urinary incontinence. Sacrospinous fixation is a procedure performed by gynecologists to treat vaginal prolapse. The present study aims to evaluate the impact of transvaginal prolapse surgery on anorectal function. Materials and Methods: We conducted a retrospective review of patients undergoing sacrospinous fixation surgery for vaginal prolapse between 2014 to 2020. Those with anorectal dysfunction who had also been evaluated by the colorectal service preoperatively and postoperatively were included for analysis. These patients were assessed with symptom-specific validated questionnaires. The effect of surgery on constipation and fecal incontinence symptoms was analyzed. Results: A total of 22 patients were included for analysis. All patients underwent transvaginal sacrospinous fixation, and 95.4% also had posterior colporrhaphy for vaginal prolapse. There were a statistically significant improvements in the Fecal Incontinence Severity Index (FISI), the St. Mark's Incontinence Score (Vaizey), the embarrassment and lifestyle components of the Fecal Incontinence Quality of Life Score, the Constipation Scoring System, the Obstructed Defecation Score, and components of the Patient Assessment of Constipation Quality of Life score. Conclusion: Transvaginal prolapse surgery leads to a favorable effect on anorectal function, with improvements in both obstructed defecation and fecal incontinence scores in this small series. (AU)

Surviving rectal cancer at the cost of a colostomy: global survey of long-term health-related quality of life in 10 countries.

BACKGROUND: Colorectal cancer management may require an ostomy formation; however, a stoma may negatively impact health-related quality of life (HRQoL). This study aimed to compare generic and stoma-specific HRQoL in patients with a permanent colostomy after rectal cancer across different countries. METHOD: A cross-sectional cohorts of patients with a colostomy after rectal cancer in Denmark, Sweden, Spain, the Netherlands, China, Portugal, Australia, Lithuania, Egypt, and Israel were invited to complete questionnaires regarding demographic and socioeconomic factors along with the Colostomy Impact (CI) score, European Organisation for Research and Treatment of Cancer (EORTC) Quality of Life Questionnaire (QLQ-C30) and five anchor questions assessing colostomy impact on HRQoL. The background characteristics of the cohorts from each country were compared and generic HRQoL was measured with the EORTC QLQ-C30 presented for the total cohort. Results were compared with normative data of reference European populations. The predictors of reduced HRQoL were investigated by multivariable logistic regression, including demographic and socioeconomic factors and stoma-related problems. RESULTS: A total of 2557 patients were included. Response rates varied between 51-93 per cent. Mean time from stoma creation was 2.5-6.2 (range 1.1-39.2) years. A total of 25.8 per cent of patients reported that their colostomy impairs their HRQoL 'some'/'a lot'. This group had significantly unfavourable scores across all EORTC subscales compared with patients reporting 'no'/'a little' impaired HRQoL. Generic HRQoL differed significantly between countries, but resembled the HRQoL of reference populations. Multivariable logistic regression showed that stoma dysfunction, including high CI score (OR 3.32), financial burden from the stoma (OR 1.98), unemployment (OR 2.74), being single/widowed (OR 1.35) and young age (OR 1.01 per year) predicted reduced stoma-related HRQoL. CONCLUSION: Overall HRQoL is preserved in patients with a colostomy after rectal cancer, but a quarter of the patients interviewed reported impaired HRQoL. Differences among several countries were reported and socioeconomic factors correlated with reduced quality of life.

Development of 3D Printed Biodegradable Mesh with Antimicrobial Properties for Pelvic Organ Prolapse.

To address the increasing demand for safe and effective treatment options for pelvic organ prolapse (POP) due to the worldwide ban of the traditional polypropylene meshes, this study introduced degradable polycaprolactone (PCL)/polyethylene glycol (PEG) composite meshes fabricated with melt-electrowriting (MEW). Two PCL/PEG mesh groups: 90:10 and 75:25 (PCL:PEG, wt%) were fabricated and characterized for their degradation rate and mechanical properties, with PCL meshes used as a control. The PCL/PEG composites showed controllable degradation rates by adjusting the PEG content and produced mechanical properties, such as maximal forces, that were higher than PCL alone. The antibacterial properties of the meshes were elicited by coating them with a commonly used antibiotic: azithromycin. Two dosage levels were used for the coating: 0.5 mg and 1 mg per mesh, and both dosage levels were found to be effective in suppressing the growth of S. aureus bacteria. The biocompatibility of the meshes was assessed using human immortalized adipose derived mesenchymal stem cells (hMSC). In vitro assays were used to assess the cell viability (LIVE/DEAD assay), cell metabolic activity (alamarBlue assay) and cell morphology on the meshes (fluorescent and electron microscopy). The cell attachment was found to decrease with increased PEG content. The freshly drug-coated meshes showed signs of cytotoxicity during the cell study process. However, when pre-released for 14 days in phosphate buffered saline, the initial delay in cell attachment on the drug-coated mesh groups showed full recovery at the 14-day cell culture time point. These results indicated that the PCL/PEG meshes with antibiotics coating will be an effective anti-infectious device when first implanted into the patients, and, after about 2 weeks of drug release, the mesh will be supporting cell attachment and proliferation. These meshes demonstrated a potential effective treatment option for POP that may circumvent the issues related to the traditional polypropylene meshes.

A prospective trial of the THD SphinKeeper® for faecal incontinence.

AIM: THD SphinKeeper® is an emerging surgical technique for faecal incontinence (FI). The safety, indications and efficacy of the procedure are still being investigated. The aim of this study is to present the first experience of SphinKeeper® in Australia. METHOD: This was a prospective single-centre observational study of patients undergoing SphinKeeper® implantation between February 2018 and September 2019. Baseline demographics, intraoperative and postoperative complications, Cleveland Clinic Faecal Incontinence Score, St Mark's Incontinence Score, Faecal Incontinence Quality of Life score (FIQOL), anorectal manometry and endo-anal ultrasound were assessed preoperatively and 3 and 12 months after implantation. RESULTS: Thirteen patients (2 male, 11 female) underwent implantation during the study period. Anal sphincter defects were present in 13 (76.9%) patients [external anal sphincter (EAS) defect, 2 (15.4%); internal anal sphincter (IAS) defect 4 (30.8%); EAS + IAS defect, 4 (30.8%)]. Median follow-up was 32 months (range 18-37 months). There were four complications: one intraoperative (rectal perforation) and three postoperative (one implant extrusion, two implants that required removal due to malposition). At 12 months, an average of 9/10 implants remained ideally placed in each patient. THD SphinKeeper® insertion was associated with an improvement in coping/behaviour as measured using FIQOL (p = 0.047). However, the procedure did not improve FI scores or anorectal manometry parameters. CONCLUSION: In this study, SphinKeeper® marginally improved symptoms of FI but there was no significant impact on anorectal manometric measurements. Larger-scale studies are needed to determine the patient cohort most likely to benefit from this procedure.

The Vertical Rectus Abdominis Myocutaneous Flap to Manage Vaginal Evisceration.

BACKGROUND: Pelvic organ prolapse (POP) is a significant issue requiring surgical correction in 19% of the female population by age 85 years. Complications of POP, especially in women who have undergone hysterectomy, include vaginal evisceration-a serious complication that carries high morbidity and mortality rates. Rarely, vaginal evisceration occurs after colpocleisis. CASE: A 69-year-old female with recurrent vaginal evisceration following colpocleisis underwent surgical repair using a vertical rectus abdominis myocutaneous (VRAM) flap. CONCLUSION: Recurrent cases of POP and vaginal evisceration that are refractory to conventional treatment require consideration of novel management options. To our knowledge, this is the first case using a VRAM flap for the management of vaginal evisceration.

European Society of Coloproctology guidance on the use of mesh in the pelvis in colorectal surgery.

This is a comprehensive and rigorous review of currently available data on the use of mesh in the pelvis in colorectal surgery. This guideline outlines the limitations of available data and the challenges of interpretation, followed by best possible recommendations.

A comparison of faecal incontinence scoring systems.

AIM: Questionnaires designed to score the severity of faecal incontinence (FI) are widely used to provide an evaluation of symptoms across settings, studies and time. The Pelvic Floor Disorders Consortium have recommended the use of multiple questionnaires despite some overlap of questions. This study aimed to evaluate whether patient responses to these questionnaires are consistent. METHOD: A retrospective analysis was undertaken of patients with FI who attended a dedicated pelvic floor unit between January 2018 and December 2019 and completed the Fecal Incontinence Severity Index, Cleveland Clinic Florida Incontinence Score and St Mark's Incontinence Score simultaneously. For each questionnaire the frequency of incontinence episodes to solid stool, liquid stool and gas was divided into five categories to allow direct comparison. Answers were deemed equivalent if the allocated response was identical, slightly different if the response was in an adjacent category or very different if the response differed to a greater extent. RESULTS: There were 193 patients who simultaneously completed all three FI questionnaires. There were statistically significant differences between the responses regarding frequency of solid stool, liquid stool and gas incontinence on all three questionnaires (p < 0.005). Across all domains, between 58.0% and 69.9% of responses were equivalent, 14.1%-34.0% of answers were slightly different and 8.0%-18.8% were very different. CONCLUSION: Even when completed at the same time, and by the same person, similar questions are answered differently a significant proportion of the time. The utility of using multiple questionnaires simultaneously in the clinical setting to assess FI symptoms should be questioned.

Translation and international validation of the Colostomy Impact score.

AIM: Optimal oncological resection in cancers of the lower rectum often requires a permanent colostomy. However, in some patients a colostomy may have a negative impact on health-related quality of life (HRQoL). The Colostomy Impact (CI) score is a simple questionnaire that identifies patients with stoma dysfunction that impairs HRQoL by dividing patients into 'minor' and 'major' CI groups. This aim of this study is to evaluate construct and discriminative validity, sensitivity, specificity and reliability of the CI score internationally, making it applicable for screening and identification of patients with stoma-related impaired HRQoL. METHOD: The CI score was translated in agreement with WHO recommendations. Cross-sectional cohorts of rectal cancer survivors with a colostomy in Australia, China, Denmark, the Netherlands, Portugal, Spain and Sweden were asked to complete the CI score, the European Organization for Research and Treatment of Cancer (EORTC) quality of life 30-item core questionnaire, the stoma-specific items of the EORTC quality of life 29-item colorectal-specific questionnaire and five anchor questions assessing the impact of colostomy on HRQoL. RESULTS: A total of 2470 patients participated (response rate 51%-93%). CI scores were significantly higher in patients reporting reduced HRQoL due to their colostomy than in patients reporting no reduction. Differences in EORTC scale scores between patients with minor and major CI were significant and clinically relevant. Sensitivity was high regarding dissatisfaction with a colostomy. Regarding evaluation of discriminative validity, the CI score relevantly identified groups with differences in HRQoL. The CI score proved reliable, with equal CI scores between test and retest and an intraclass correlation coefficient in the moderate to excellent range. CONCLUSION: The CI score is internationally valid and reliable. We encourage its use in clinical practice to identify patients with stoma dysfunction who require further attention.

Transperineal rectocele repair: a systematic review.

BACKGROUND: Transperineal rectocele repairs, either as isolated fascial repair or in combination with mesh augmentation, are hypothesized to reduce the risk of complications compared with alternative techniques. AIM: The aim of this study was to ascertain long-term success and complication rates following transperineal rectocele repairs. METHOD: A literature search of PubMed and Embase was performed using the terms 'transperineal rectocele', 'rectocele', 'transperineal' and 'repair'. Prospective studies, case series and retrospective case note analyses from 1 January 1994 to 1 December 2016 were included. Those that detailed outcomes of the transperineal approach or compared it to transanal/transvaginal approaches were included. The main outcome measures were reported complications and functional outcome scores. RESULTS: A total of 14 studies were included. Of 566 patients, 333 (58.8%) underwent a transperineal rectocele repair and 220 (41.2%) a transanal repair. Complications were identified in 27 (12.3%) of the 220 transanal repairs and in 41 (12.3%) of the 333 transperineal repairs. A significant complication following transperineal repair was noted in eight studies. There are not enough data to make a reliable comparison between mesh and non-mesh transperineal repairs or to compare biological and synthetic mesh use. LIMITATIONS: Outcome reporting differed between studies, precluding a full meta-analysis. CONCLUSION: Transperineal rectocele repair offers an effective method of symptom improvement and appears to have a similar complication rate as transanal rectocele repair. Concomitant use of synthetic and biological mesh augmentation is becoming more common; however, high-quality comparative data are lacking, so a direct comparison between surgical approaches is not yet possible.

Retro-rectus repair of complex incisional hernia leads to low recurrence rate.

BACKGROUND: To assess the outcome of retro-rectus repair of complex abdominal wall repair (CAWR) in a single institution in relation to the use of biologic and synthetic mesh. METHOD: A retrospective review was undertaken of complex abdominal wall repairs performed by a single surgical team, assessing the outcome of the retro-rectus repair and factors affecting the outcome. RESULTS: Between 2007 and 2013, 57 (33 male) patients underwent CAWR retro-rectus repair. The material used was assessed as either synthetic or biologic (cross-linked porcine dermal collagen). The Ventral Hernia Working Group grades were similar between groups of patients having a repair with synthetic and biologic mesh. Median follow-up in the synthetic group was 18 months (1-80.5) and 18.4 months (0.5-70.7) in the biologic group. There was no statistical difference in seroma, wound infection or haematoma rates. No fistulae occurred in either group. Overall recurrence was 3.4% and there was no statistical difference between groups. CONCLUSION: The retro-rectus repair technique is associated with a low rate of recurrence and is now the technique of choice. The choice of material, biologic or synthetic, in Ventral Hernia Working Group grades 1-3 remains controversial.

Recovery following injury hinges upon expectation and hope.

Recovery following trauma depends on many factors and is not related to only the physical severity of injury. Different people respond differently to the stress of injury and, therefore, recover differently. Support networks are important. Expectation and hope, which can be greatly influenced by responsible health care professionals, can hugely influence recovery.

Closed reduction and stabilization of supracondylar fractures of the humerus in children: the crucial factor of surgical experience.

We reviewed the outcome following operative management of displaced (Gartland II and III) supracondylar fractures of the humerus in children over a 2-year period and tried to correlate the outcome with various factors including experience of the treating surgeon. Of the 71 children who formed the study group, 62 (87.3%) had a good outcome irrespective of the treatment modality. Closed reduction followed by plaster immobilization or percutaneous pinning resulted in a better outcome than open reduction. There was a direct involvement of the consultant in the primary management of these injuries in 17 cases (24%), none of which had a poor outcome. Of the 54 cases in whom the primary management was carried out independently by trainees without any consultant supervision, nine patients (17%) developed complications or needed reoperations. The proportion of unsatisfactory outcomes increased to 20.3% when failure to achieve a satisfactory reduction by closed means was also considered as a perioperative complication. There is a learning curve associated with percutaneous pinning after closed reduction and experience of the surgeon seems to be one of the factors that have an influence on the outcome.
