ABSTRACT
AIM: The incidence of obstetric anal sphincter injuries (OASIS) has increased in the past two decades despite improved awareness of the risk factors. This study aimed to define the incidence of OASIS in women with different features (instrumental delivery or other variables). METHODS: A systematic review was conducted on articles reporting the incidence of OASIS. This review aims to examine the association of instrumentation and OASIS by performing a formal systematic review of the published literature. Databases used for the research were MEDLINE, Embase, CINAHL and 'Maternity and infant care' databases. RESULTS: Two independent reviewers screened the selected articles. 2326 duplicates were removed from the total of 4907 articles. The remaining 2581 articles were screened for title and abstract. 1913 articles were excluded due to irrelevance. The remaining 300 were screened as full text. Primiparity associated with the use of forceps were the features associated with the highest incidence of OASIS in the selected articles (19.4%). OASIS in all women had an overall incidence of 3.8%. The incidence of OASIS in all women by geographical region was the highest (6.5%) in North America. CONCLUSIONS: There are various factors that impact on the incidence of OASIS and the combination of some of these, such as the use of forceps in primiparas, resulted in the highest incidence of OASIS. The lack of international consensus is limiting the improvements that can be done to reduce OASIS rates and improve best clinical practice.

INTRODUCTION: The goal of this project was to create an up-to-date joint European clinical practice guideline for the diagnosis and treatment of faecal incontinence (FI), using the best available evidence. These guidelines are intended to help guide all medical professionals treating adult patients with FI (e.g., general practitioners, surgeons, gastroenterologists, other healthcare workers) and any patients who are interested in information regarding the diagnosis and management of FI. METHODS: These guidelines have been created in cooperation with members from the United European Gastroenterology (UEG), European Society of Coloproctology (ESCP), European Society of Neurogastroenterology and Motility (ESNM) and the European Society for Primary Care Gastroenterology (ESPCG). These members made up the guideline development group (GDG). Additionally, a patient advisory board (PAB) was created to reflect and comment on the draft guidelines from a patient perspective. Relevant review questions were established by the GDG along with a set of outcomes most important for decision making. A systematic literature search was performed using these review questions and outcomes as a framework. For each predefined review question, the study or studies with the highest level of study design were included. If evidence of a higher-level study design was available, no lower level of evidence was sought or included. Data from the studies were extracted by two reviewers for each predefined important outcome within each review question. Where possible, forest plots were created. After summarising the results for each review question, a systematic quality assessment using the GRADE (Grading of Recommendations, Assessment, Development and Evaluations) approach was performed. For each review question, we assessed the quality of evidence for every predetermined important outcome. After evidence review and quality assessment were completed, recommendations could be formulated. The wording used for each recommendation was dependent on the level of quality of evidence. Lower levels of evidence resulted in weaker recommendations and higher levels of evidence resulted in stronger recommendations. Recommendations were discussed within the GDG to reach consensus. RESULTS: These guidelines contain 45 recommendations on the classification, diagnosis and management of FI in adult patients. CONCLUSION: These multidisciplinary European guidelines provide an up-to-date comprehensive evidence-based framework with recommendations on the diagnosis and management of adult patients who suffer from FI.

BACKGROUND: Diagnosing anal incontinence (AI) based on manometry results is challenging due to the variation of the normal values and overlap between patients with and without AI. This study aimed to perform a systematic review on the difference in sphincter fatigability between patients with and without AI. METHODS: MEDLINE, EMBASE, SCOPUS, and Google Scholar were searched. Studies were included if they included adult patients and assessed anal sphincter fatigability between using manometry. The effect size was estimated as the standardized mean difference (SMD) with 95% confidence intervals. A random-effects model was used. RESULTS: The database searches identified 125 unique articles, and five additional articles were identified from the reference list of articles. One hundred thirteen were excluded through title and abstract review. Nine articles were included in the final analysis. There was no statistically significant difference in the resting pressure between the two groups. Patients with AI had significantly lower squeeze pressure. There was no statistically significant difference between the groups in the fatigue rate. The FRI was significantly lower in patients with AI (SMD 1.636, p = 0.001). Approximately a third of the patients in one study were able to maintain a contraction for 20s without reducing pressure. There was significant heterogeneity in the studies. The data available were inadequate for more robust calculations. CONCLUSIONS: Sphincter fatigability, measured by the Fatigability Rate Index, has good discriminating power for anal incontinence. A standardized protocol needs to be followed by future researchers. Graphical Abstract The analysis used six studies with 413 patients to compare Fatigue Rate Index between patients with AI and controls. All studies reported a lower FRI in patients with incontinence and the FRI was significantly lower in patients with AI (standardized mean difference [SMD] 1.636, p= 0.001). Conflicting results were reported on the correlation between FRI and AI symptom scores.

BACKGROUND: Faecal incontinence (FI) is a disabling condition in patients with inflammatory bowel disease (IBD). The diagnosis of FI is not easy as patients are reluctant to report this embarrassing symptom. The objectives of this study were to characterize the prevalence of FI in IBD patients using available scoring systems, and to identify associated risk factors. METHODS: A FI clinic was implemented in routine practice between January 2020 and April 2021. FI was defined as a Wexner score ≥5. Factors associated with FI were analyzed. RESULTS: A total of 319 consecutive patients with IBD were included. The prevalence of FI was 16.4% (53/319). Age >45 years at inclusion (Odd ratio (OR)=3.33, Confidence interval (CI) 95% 1.40-7.94), diarrhea (three stools at least per day) (OR=2.94, CI 95% 1.16-7.45), stool consistency according to the Bristol stool chart (OR=2.23, CI 95% 1.00-4.99), and abdominal pain (OR=2.24, CI 95% 1.10-4.53) were independently associated with FI in a multivariate model analysis. CONCLUSIONS: Approximately one fifth of IBD patients reported FI in this real-world cohort, using an available scoring system. Increased age, diarrhea, stool consistency according to the Bristol stool chart, and abdominal pain were associated with FI. A systematic screening of FI would allow a better management of this disabling condition.

AIM: In intestinal failure, delineation of both structure and function are key to controlling symptoms and planning further intervention. We have developed a template for developing an 'anatomy at a glance' patient-specific map to aid decision making and counselling. METHOD: A core dataset was developed and used to create an editable template to demonstrate the gastrointestinal tract, its relationship to the genitourinary tract, and specific anterior abdominal wall features. This was then used to create an anatomical template, specific to each patient, and stored in the electronic patient record and imaging archive. RESULTS: We have developed a technique for integration of multi-modal information into one diagram, easily referenced by the multidisciplinary team. Radiology, endoscopy and previous operation notes can be used to fill out a core dataset, which is then transposed into a standardized template. A worked example is shown. CONCLUSION: The mapping template has been successfully integrated into practice and aided decision making at all stages of the patient's therapeutic journey. It has been found helpful in planning routes of nutrition, preoperative optimization, surgical planning, interpreting postoperative imaging and managing patient expectations.

BACKGROUND: Distal feeding (DF) describes the insertion of a feeding tube into a fistula or stoma to administer a liquid feed into the distal bowel. It is currently used clinically in patients who are unable to absorb enough nutrition orally. This systematic review investigates DF as a therapeutic measure across a spectrum of patients with stomas and fistulae. METHODS: A total of 2825 abstracts and 44 full-text articles were screened via OVID. Fifteen papers were included for analysis. Randomised controlled trials, cohort and observational studies investigating DF as a therapeutic measure were included. RESULTS: Three feeds were used across the studies-reinfusion of effluent, infusion of prebiotic or a mixture. The studies varied the length of feeding between 24 hours and 61 days, and the mode of feeding, bolus or continuous varied.DF was demonstrated to effectively wean patients from parenteral nutrition in two papers. Two papers demonstrated a significant reduction in stoma output. Three papers demonstrated improved postoperative complication rates with distal feeding regimens, including ileus (2.85% vs 20% in unfed population, p=0.024). One paper demonstrated a reduction in postoperative stool frequency. CONCLUSIONS: This review was limited by study heterogeneity and the lack of trial data, and in the patient groups involved, the variability in diet and length of regimen. These studies suggest that DF can significantly reduce stoma output and improve renal and liver function; however, the mechanism is not clear. Further mechanistic work on the immunological and microbiological action of DF would be important.
ABSTRACT
PURPOSE: To define the change in Emergency Surgical Unit (ESU) workload during the COVID-19 pandemic. METHODS: Patient data for a three-week period was prospectively collected for ESU patients during lockdown period and compared to the ESU workload for the same time period prior to lockdown. RESULTS: Surgical emergencies admissions reduced by 2.5 times during our study period (p value = 0.001). In this changed paradigm, the overall number of surgical emergencies were reduced. A high mortality (n = 4, 5.7%) was noted during lockdown period as compared to pre-lockdown period (n = 1, 0.58%, p value = 0.025). Almost half of surgical admissions were tested for COVID-19 based on their symptoms and more than third (n=14, 38.9%) of them were positive. Gastrointestinal symptoms were common in COVID-19 positive group (85.7%) and only a third (36%) of COVID-19 positive patients needed surgical attention. Chest x-ray findings were comparable to PCR testing in terms of sensitivity and specificity but CT chest was more sensitive. CONCLUSIONS: It remains unclear how COVID-19 reduced surgical emergencies. A significant proportion of COVID-19 presented with gastrointestinal symptoms. In a new outbreak all General Surgical patients should be tested with CRP and WCC used as a triage adjunct. KEY WORDS: Coronavirus, COVID-19, Emergency Surgery Pandemic, General Surgery.

PURPOSE: Faecal incontinence (FI) is estimated to affect around 7.7% of people. There is a lack of uniformity in outcome definitions, measurement and reporting in FI studies. Until now, there is no general consensus on which outcomes should be assessed and reported in FI research. This complicates comparison between studies and evidence synthesis, potentially leading to recommendations not evidence-based enough to guide physicians in selecting an FI therapy. A solution for this lack of uniformity in reporting of outcomes is the development of a Core Outcome Set (COS) for FI. This paper describes the protocol for the development of a European COS for FI. METHODS: Patient interviews and a systematic review of the literature will be performed to identify patient-, physician- and researcher-oriented outcomes. The outcomes will be categorised using the COMET taxonomy and put forward to a group of patients, physicians (i.e. colorectal surgeons, gastroenterologists and general practitioners) and researchers in a Delphi consensus exercise. This exercise will consist of up to three web-based rounds in which participants will prioritise and condense the list of outcomes, which is expected to result in consensus. A consensus meeting with participants from all stakeholder groups will take place to reach a final agreement on the COS. DISCUSSION: This study protocol describes the development of a European COS to improve reliability and consistency of outcome reporting in FI studies, thereby improving evidence synthesis and patient care.

PURPOSE: To compare the current clinical scoring systems used to quantify the severity of symptoms of faecal incontinence (FI) to patients' subjective scoring of parameters of psychosocial well-being. METHODS: Patients referred to six European centres for investigation or treatment of symptoms of FI between June 2017 and September 2019 completed a questionnaire that captured patient demographics, incontinence symptoms using St. Mark's Incontinence score (SMIS) and ICIQ-B, psychological well-being (HADS, Hospital Anxiety and Depression Scale), and social interaction (a three-item loneliness scale). RESULTS: Three hundred eighteen patients completed questionnaires (62 men, mean age 58.7). Sixty percent of the respondents were aged under 65. Median SMIS was 15 (11-18), ICIQ-B bowel pattern was 8 (6-11) and bowel control was 17 (13-22), similar across all demographic groups; however, younger patients were more likely to experience symptoms of depression and anxiety (HADS score > 10, 65.2% of patients age < 65 vs 54.9% of those ages > = 65, p = 0.03) with lower quality of life (ICIQ-B QoL, median score 19 (14-23)) vs age > = 65 (16 (11-21) (p < 0.005)). On loneliness score 25.5% reported often feeling isolated from others. One of the most significant concerns by patients was the fear and embarrassment related to unpredictable episodes of incontinence. CONCLUSION: The SMIS remains a useful tool for quantifying incontinence symptoms but may underestimate the psychosocial morbidity associated with unpredictable episodes of incontinence. Interventions aimed at decreasing anxiety and to address feelings of disgust may be helpful for a significant number of patients requiring treatment for FI.

BACKGROUND: Anal inserts and percutaneous tibial nerve stimulation may be offered to those with fecal incontinence in whom other conservative treatments have failed. OBJECTIVE: We aimed to compare anal inserts and percutaneous tibial nerve stimulation. DESIGN: This was an investigator-blinded randomized pilot study. SETTINGS: The study was conducted at a large tertiary care hospital. PATIENTS: Adult patients with passive or mixed fecal incontinence were recruited. INTERVENTIONS: Patients were randomly assigned to receive either the anal inserts or weekly percutaneous tibial nerve stimulation for a period of 3 months. MAIN OUTCOME MEASURES: The primary end point was a 50% reduction of episodes of fecal incontinence per week as calculated by a prospectively completed 2-week bowel diary. Secondary end points were St Mark's incontinence score, International Consultation on Incontinence Questionnaire-Bowel scores (for bowel pattern, bowel control, and quality of life), use of antidiarrheal agents, estimates of comfort and acceptability. RESULTS: Fifty patients were recruited: 25 were randomly assigned to anal inserts and 25 were randomly assigned to percutaneous tibial nerve stimulation. All completed treatment. A significant improvement of scores in the 2-week bowel diary, the St Mark's scores and the International Consultation on Incontinence Questionnaire-Bowel scores, was seen in both groups after 3 months of treatment. A reduction of ≥50% fecal incontinence episodes was reached by 76% (n = 19/25) by the anal insert group, compared with 48% (n = 12/25) of those in the percutaneous tibial nerve stimulation group (p = 0.04). The St Mark's fecal incontinence scores and the International Consultation on Incontinence Questionnaire-Bowel scores for bowel pattern, bowel control, and quality of life (p = 0.01) suggest similar improvement for each group. LIMITATIONS: A realistic sample size calculation could not be performed because of the paucity of objective prospective studies assessing the effect of the insert device and percutaneous tibial nerve stimulation. CONCLUSIONS: Both anal insert and percutaneous tibial nerve stimulation improved the symptoms of fecal incontinence after 3 months of treatment. The insert device appeared to be more effective than percutaneous tibial nerve stimulation. Larger studies are needed to investigate this further. See Video Abstract at http://links.lww.com/DCR/B460.

ESTUDIO PILOTO ALEATORIZADO DE INSERCIONES ANALES CONTRA LA ESTIMULACIN PERCUTNEA DEL NERVIO TIBIAL EN PACIENTES CON INCONTINENCIA FECAL: ANTECEDENTES:Las inserciones anales y la estimulación percutánea del nervio tibial (PTNS) se pueden ofrecer a las personas con incontinencia fecal que han fallado en otros tratamientos conservadores.OBJETIVO:Nuestro objetivo fue comparar inserciones anales y estimulación percutánea del nervio tibial.DISEÑO:Este fue un estudio piloto aleatorio ciego para investigadores.AJUSTE:El estudio se realizó en un hospital de atención terciaria.PACIENTES:Se reclutaron pacientes adultos con incontinencia fecal pasiva o mixta.INTERVENCIONES:Los pacientes fueron asignados al azar para recibir inserciones anales o estimulación del nervio tibial percutáneo semanal durante un período de tres meses.PRINCIPALES MEDIDAS DE RESULTADO:El principal resultado fue una reducción del 50% de los episodios de incontinencia fecal por semana, según lo calculado mediante un diario intestinal de dos semanas completado de forma prospectiva. Los criterios de valoración secundarios fueron la puntuación de incontinencia de St Mark, las puntuaciones del ICIQ-B (para patrón intestinal, control intestinal y calidad de vida), uso de agentes antidiarreicos, estimaciones de comodidad y aceptabilidad.RESULTADOS:Se reclutaron 50 pacientes: 25 fueron asignados al azar a inserciones anales y 25 a PTNS. Todo el tratamiento completado. Se observó una mejora significativa de las puntuaciones en el diario intestinal de dos semanas, la puntuación de St Mark y la puntuación del ICIQ-B en ambos grupos después de 3 meses de tratamiento. Se alcanzó una reducción de ≥ 50% de los episodios de incontinencia fecal en un 76% (n = 19/25) en el grupo de inserción anal, en comparación con el 48% (n = 12/25) de los del grupo de estimulación percutánea del nervio tibial (p = 0,04). Las puntuaciones de incontinencia fecal de St Mark, las puntuaciones del ICIQ-B para el patrón intestinal, el control intestinal y la calidad de vida (p = 0,01) sugieren una mejora similar para cada grupo.LIMITACIONES:No se pudo realizar un cálculo realista del tamaño de la muestra debido a la escasez de estudios prospectivos objetivos que evaluaran el efecto del dispositivo de inserción y la estimulación percutánea del nervio tibial.CONCLUSIONES:Tanto la inserción anal como la estimulación percutánea del nervio tibial mejoraron los síntomas de incontinencia fecal después de 3 meses de tratamiento. El dispositivo de inserción parecia ser más efectivo que la estimulación percutánea del nervio tibial. Se necesitan estudios más amplios para investigar esto más a fondo.

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.

BACKGROUND: This manuscript summarizes consensus reached by the International Anorectal Physiology Working Group (IAPWG) for the performance, terminology used, and interpretation of anorectal function testing including anorectal manometry (focused on high-resolution manometry), the rectal sensory test, and the balloon expulsion test. Based on these measurements, a classification system for disorders of anorectal function is proposed. METHODS: Twenty-nine working group members (clinicians/academics in the field of gastroenterology, coloproctology, and gastrointestinal physiology) were invited to six face-to-face and three remote meetings to derive consensus between 2014 and 2018. KEY RECOMMENDATIONS: The IAPWG protocol for the performance of anorectal function testing recommends a standardized sequence of maneuvers to test rectoanal reflexes, anal tone and contractility, rectoanal coordination, and rectal sensation. Major findings not seen in healthy controls defined by the classification are as follows: rectoanal areflexia, anal hypotension and hypocontractility, rectal hyposensitivity, and hypersensitivity. Minor and inconclusive findings that can be present in health and require additional information prior to diagnosis include anal hypertension and dyssynergia. CONCLUSIONS AND INFERENCES: This framework introduces the IAPWG protocol and the London classification for disorders of anorectal function based on objective physiological measurement. The use of a common language to describe results of diagnostic tests, standard operating procedures, and a consensus classification system is designed to bring much-needed standardization to these techniques.

Sacral nerve stimulation (SNS) is an established treatment for faecal incontinence involving the implantation of a quadripolar electrode into a sacral foramen, through which an electrical stimulus is applied. Little is known about the induced spread of electric current around the SNS electrode and its effect on adjacent tissues, which limits optimisation of this treatment. The authors constructed a 3-dimensional imaging based finite element model in order to calculate and visualise the stimulation induced current and coupled this to biophysical models of nerve fibres. They investigated the impact of tissue inhomogeneity, electrode model choice and contact configuration and found a number of effects. (i) The presence of anatomical detail changes the estimate of stimulation effects in size and shape. (ii) The difference between the two models of electrodes is minimal for electrode contacts of the same length. (iii) Surprisingly, in this arrangement of electrode and neural fibre, monopolar and bipolar stimulation induce a similar effect. (iv) Interestingly when the active contact is larger, the volume of tissue activated reduces. This work establishes a protocol to better understand both therapeutic and adverse stimulation effects and in the future will enable patient-specific adjustments of stimulation parameters.
ABSTRACT
BACKGROUND & AIMS: Home parenteral nutrition (HPN) is provided to patients with intestinal failure (IF). HPN can however affect the patients' quality of life and ability to remain in employment. The aim of this study was to determine the effect of HPN on employment and factors associated with the likelihood of maintaining or returning to employment while on HPN. METHODS: Patients with chronic IF were identified from a prospectively maintained IF Unit database. A structured questionnaire was designed to probe employment both before and after starting HPN, intention to work and social welfare status (benefits & pensions). RESULTS: A total of 196 (62.8% females, median age 53 years) patients participated in the study of which 184 (94%) patients were in full or part time employment before their illness. At the time of starting HPN, 102 (52%) patients had the desire to return to work with 19 (18%) and 48 (47%) patients returning to full time or part time employment respectively. Multivariate analysis demonstrated that the frequency of the HPN infusion per week (p = 0.045) and intention to work after starting HPN (p = 0.001) were significantly associated with returning to work. CONCLUSIONS: Patients on HPN can have their employment status affected. The number of days per week on HPN and the desire of the patient to return to employment are significantly associated with employment.

INTRODUCTION: There is a paucity of data on incidence and mechanisms of long-term gastrointestinal consequences after chemoradiotherapy for anal cancer. Most of the adverse effects reported were based on traditional external beam radiotherapy whilst only short-term follow-ups have been available for intensity-modulated radiotherapy, and there is lack of knowledge about consequences of dose-escalation radiotherapy. METHOD: A systematic literature review. RESULTS: Two thousand nine hundred and eighty-five titles (excluding duplicates) were identified through the search; 130 articles were included in this review. The overall incidence of late gastrointestinal toxicity was reported to be 7-64.5%, with Grade 3 and above (classified as severe) up to 33.3%. The most commonly reported late toxicities were fecal incontinence (up to 44%), diarrhea (up to 26.7%), and ulceration (up to 22.6%). Diarrhea, fecal incontinence and buttock pain were associated with lower scores in radiotherapy specific quality of life scales (QLQ-CR29, QLQ-C30, and QLQ-CR38) compared to healthy controls. Intensity-modulated radiation therapy appears to reduce late toxicity. CONCLUSION: Late gastrointestinal toxicities are common with severe toxicity seen in one-third of the patients. These symptoms significantly impact on patients' quality of life. Prospective studies with control groups are needed to elucidate long-term toxicity.
