Critical appraisal of international guidelines for the management of fecal incontinence in adults: is it possible to define what to do in different clinical scenarios?

Treatment options for postoperative faecal incontinence after colorectal surgery

Postoperative faecal incontinence is a common and challenging complication following colorectal surgery, significantly impacting patients' quality of life. This article provides an overview of the types of colorectal surgical interventions that may contribute to faecal incontinence and explores various treatment options, ranging from conservative management to surgery. Conservative approaches include dietary modifications, bowel training and pharmacological treatments such as bulking agents, antidiarrhoeal medications and biofeedback therapy. For patients with persistent symptoms, advanced therapies such as sacral and tibial nerve stimulation are considered. Surgical options including sphincter repair, pouch formation, artificial anal sphincter implant or colostomy may be required for severe cases. The article reviews the most common treatment modalities, emphasising the importance of an individualised approach. Multidisciplinary care involving colorectal surgeons, physiotherapists and gastroenterologists is essential for optimising outcomes. Ultimately, the management of postoperative faecal incontinence requires careful assessment of the underlying cause, severity of symptoms and patient preferences to guide treatment selection.

Experimental evaluation of an artificial anal sphincter based on biomechanical compatibility

BACKGROUND

The artificial anal sphincter is a device used to treat patients with fecal incontinence who are unable to control their bowel movements on their own. Long-term morphological changes in the tissue surrounding the artificial anal sphincter can cause biomechanical compatibility problems, which seriously affect the clinical application of the artificial anal sphincter.

METHODS

In this paper, the superelasticity of shape memory alloys was utilized to design and fabricate a biomechanically compatible constant force clamping artificial anal sphincter. An in vitro simulation system was constructed to verify the effectiveness, safety, and constant force characteristics of the artificial anal sphincter.

RESULTS

The experimental results demonstrated that the artificial anal sphincter could be effectively closed with no leakage of the liquid-like intestinal contents, which are most likely to leak. The pressure of the artificial anal sphincter on the intestinal tube gradually increased and eventually became constant during closure, and the pressure value was always less than the intestinal blood supply pressure threshold.

CONCLUSIONS

In this paper, we designed an artificial anal sphincter based on biomechanical compatibility and the corresponding in vitro simulation experimental program and preliminarily verified the effectiveness, safety, and constant force characteristics of the artificial anal sphincter.

Management of Fecal Incontinence: Etiology, Diagnostic Approach, and Conservative Therapy

Background

Fecal incontinence is a common problem especially in the elderly resulting in a reduced quality of life.

Summary

The etiology of fecal incontinence is often multifactorial with little options for a causal therapy. The mechanisms causing incontinence can be detected by sophisticated methods in most of the patients. Using therapeutic algorithms, incontinence can be improved or even continence restored in many patients.

Key Messages

Diagnostic work-up starts with history, digital investigation, and anoproctoscopy. The specialist will further investigate with anorectal manometry, anal endosonography, and electromyography of the external anal sphincter muscle. Nonoperative therapy comprises hygienic methods, medical therapy, intraanal electrostimulation, and training methods like pelvic floor exercises or biofeedback. Second-line conservative therapies are tibial nerve stimulation, transanal irrigation, or anal inserts.

Baiona's Consensus Statement for Fecal Incontinence. Spanish Association of Coloproctology

Faecal incontinence (FI) is a major health problem, both for individuals and for health systems. It is obvious that, for all these reasons, there is widespread concern for healing it or, at least, reducing as far as possible its numerous undesirable effects, in addition to the high costs it entails. There are different criteria for the diagnostic tests to be carried out and the same applies to the most appropriate treatment, among the numerous options that have proliferated in recent years, not always based on rigorous scientific evidence. For this reason, the Spanish Association of Coloproctology (AECP) proposed to draw up a consensus to serve as a guide for all health professionals interested in the problem, aware, however, that the therapeutic decision must be taken on an individual basis: patient characteristics/experience of the care team. For its development it was adopted the Nominal Group Technique methodology. The Levels of Evidence and Grades of Recommendation were established according to the criteria of the Oxford Centre for Evidence-Based Medicine. In addition, expert recommendations were added briefly to each of the items analysed.

Faecal incontinence-a comprehensive review

Introduction

Faecal incontinence (FI) is a distressing and often stigmatizing condition characterised as the recurrent involuntary passage of liquid or solid faeces. The reported prevalence of FI exhibits considerable variation, ranging from 7 to 15% in the general population, with higher rates reported among older adults and women. This review explores the pathophysiology mechanisms, the diagnostic modalities and the efficiency of treatment options up to date.

Methods

A review of the literature was conducted to identify the pathophysiological pathways, investigation and treatment modalities.

Result and discussion

This review provides an in-depth exploration of the intricate physiological processes that maintain continence in humans. It then guides the reader through a detailed examination of diagnostic procedures and a thorough analysis of the available treatment choices, including their associated success rates. This review is an ideal resource for individuals with a general medical background and colorectal surgeons who lack specialized knowledge in pelvic floor disorders, as it offers a comprehensive understanding of the mechanisms, diagnosis, and treatment of faecal incontinence (FI).

Young women and elderly men at risk of severe faecal incontinence: results of a French nationwide database analysis : Faecal incontinence in France

PURPOSE

The incidence of severe faecal incontinence (FI) in young people is likely underestimated. The objective of this study is to assess the incidence of FI by using the French national insurance information system (SNDS).

METHODS

The SNDS was used, including 2 health insurance claims databases. The study included 49,097,454 French people who were ≥ 20 years old in 2019. The main outcome measure was the occurrence of FI.

RESULTS

In 2019, 123,630 patients out of the entire French population (n = 49 097 454) (0.25%) were treated for FI. The numbers of male and female patients were similar. The data showed a dramatic increase in the incidence of FI between the ages of 20 and 59 in female patients, compared to 60 and 79 in male patients. The risk of FI increased with age (OR of 3.6 to 11.3 depending on age). Women had a higher risk of severe FI compared to men between the ages of 20 and 39 (OR = 1.3; 95%CI:1.3-1.4) and the ages of 40 and 59 (OR = 1.1; 95%CI:1.08-1.13). This risk decreased after the age of 80 (OR = 0.96; 95%CI:0.93-0.99). The rate of diagnosis of FI also increased where there were greater numbers of proctologists practising in the region of residence in question (OR of 1.07 to 1.35 depending on the number of proctologists).

CONCLUSION

Young women who have given birth and elderly men are at risk of FI and must be targeted by public health information campaigns. The development of coloproctology networks should be encouraged.
