OBJECTIVE: Digestive stoma are frequently performed. The last French guidelines have been published twenty years ago. Our aim was to update French clinical practice guidelines for the perioperative management of digestive stoma and stoma-related complications.
METHODS: A systematic literature review of French and English articles published between January 2000 and May 2022 was performed. Only digestive stoma for fecal evacuation in adults were considered. Stoma in children, urinary stoma, digestive stoma for enteral nutrition, and rare stoma (Koch, perineal) were not included.
RESULTS: Guidelines include the surgical landmarks to create digestive stoma (ideal location, mucocutaneous anastomosis, utility of support rods, use of prophylactic mesh), the perioperative clinical practice guidelines (patient education, preoperative ostomy site marking, postoperative equipment, prescriptions, and follow-up), the management of early stoma-related complications (difficulties for nursing, high output, stoma necrosis, retraction, abscess and peristomal skin complications), and the management of late stoma-related complications (stoma prolapse, parastomal hernia, stoma stenosis, late stoma retraction). A level of evidence was assigned to each statement.
CONCLUSIONS: These guidelines will be very useful in clinical practice, and allow to delete some outdated dogma.

Background: Growing evidence on the use of mesh as a prophylactic measure to prevent parastomal hernia and advances in guideline development methods prompted an update of a previous guideline on parastomal hernia prevention. Objective: To develop evidence-based, trustworthy recommendations, informed by an interdisciplinary panel of stakeholders. Methods: We updated a previous systematic review on the use of a prophylactic mesh for end colostomy, and we synthesized evidence using pairwise meta-analysis. A European panel of surgeons, stoma care nurses, and patients developed an evidence-to-decision framework in line with GRADE and Guidelines International Network standards, moderated by a certified guideline methodologist. The framework considered benefits and harms, the certainty of the evidence, patients\' preferences and values, cost and resources considerations, acceptability, equity and feasibility. Results: The certainty of the evidence was moderate for parastomal hernia and low for major morbidity, surgery for parastomal hernia, and quality of life. There was unanimous consensus among panel members for a conditional recommendation for the use of a prophylactic mesh in patients with an end colostomy and fair life expectancy, and a strong recommendation for the use of a prophylactic mesh in patients at high risk to develop a parastomal hernia. Conclusion: This rapid guideline provides evidence-informed, interdisciplinary recommendations on the use of prophylactic mesh in patients with an end colostomy. Further, it identifies research gaps, and discusses implications for stakeholders, including overcoming barriers to implementation and specific considerations regarding validity.

UNASSIGNED: People with a stoma face many unique challenges. Leakage is a significant one but is not sufficiently discussed within the wider area of health and social care.
UNASSIGNED: This study aimed to articulate and achieve consensus on the problems experienced by people with a stoma, particularly leakage, in the hope of encouraging conversations among patients, clinicians and policymakers on how to solve them.
UNASSIGNED: Output from a modified Delphi panel, consisting of patient groups, was used to create a set of calls to action, with a particular focus on the issue of leakage.
UNASSIGNED: Leakage has a large impact on daily life and can cause both physical and mental health difficulties. Peer support and specialist care can be offer considerable benefits in dealing with these.
UNASSIGNED: There are significant unmet needs for equitable access to specialist stoma care and peer support, as well as information provision for non-specialist healthcare providers. The calls to action should be implemented.

One of the biggest challenges for specialist stoma care nurses (SCNs) caring for anyone living with a stoma is that of being confronted with a problematic stoma. This can be described as an ostomy that continues to cause leakage issues for the patient which, if persistent can quickly impact negatively on their quality of life. A convex stoma appliance, also termed convexity, is a possible solution to a problematic stoma. However, the use of a convex appliance should be considered only after a thorough assessment has been undertaken by a specialist SCN. Professionally, stoma care nursing has advanced greatly in recent years and there has been a realisation that there is a need for clinical guidelines to direct practice and offer a process for the novice SCN to follow. This realisation has been the catalyst behind the development of the new guideline for the assessment and use of convexity by the Association of Stoma Care Nurses UK, which was published this year (https://ascnuk.com/). This article explores the concept of convexity and how the guideline can assist the practice of specialist SCNs, as well as that of ward and community-based nurses who wish to gain more information on using convexity within the specialist sphere of stoma care.

Medical professionals follow evidence-based practice guidelines to achieve effective patient outcomes. Traditionally, to develop guidelines, a small group of experts examine evidence then agree on a set of statements, which are then published in journals. However, more than 7000 primary care journal articles are published monthly. This study examined a different way of drawing up practice guidelines, which involved large numbers of nurses from different countries directly in developing then disseminating the guidelines to speed up acceptance and the implementation of best practice. The results were consensus-based best practice guidelines for the treatment of patients with ostomies, which have received a high level of acceptance and enthusiasm from practitioners in 27 countries.

BACKGROUND: Worldwide, stomas represent a medical and social problem. Data from the literature on stoma management are extensive but not homogeneous. In Italy, no guidelines exist for this topic. Thus, clear and comprehensive clinical guidelines based on evidence-based data and best practice are need. In 2018, the Multidisciplinary Italian Study group for STOmas, called MISSTO, was founded. The aim was to elaborate guidelines for practice management of enteral and urinary stomas in adults.
METHODS: A systematic review of the literature was performed using PubMed, National Guideline Clearinghouse, and other databases. The research included guidelines, systematic reviews, meta-analyses, randomized clinical trials, cohort studies, and case reports. Five main topics were identified: \"stoma preparation\", \"stoma creation\", \"stoma complications\", \"stoma care\", and \"stoma reversal\". The systematic review was performed for each topic, and studies were evaluated according to the GRADE system, AGREE II tool.
RESULTS: Recommendations were elaborated in the form of statements with an established grade of recommendation for each statement. For low levels of scientific evidence statements, a consensus conference composed of expert members of the major Italian scientific societies in the field of stoma management and care was held. After discussing, correcting, validating, or eliminating the statements by the experts, the final version of the guidelines was elaborated and prepared for publication. This manuscript is focused on statements on the surgical management of enteral stomas.
CONCLUSIONS: These guidelines are the first Italian guidelines on multidisciplinary management of enteral stomas with the aim of assisting surgeons during stoma management and care.

Management of deep pelvic and digestive endometriosis can lead to colorectal resection and anastomosis. Colorectal anastomosis carries risks for dreaded infectious and functional morbidity. The aim of the study was to establish, regarding the published data, the role of the three most common used surgical techniques to prevent such complications: pelvic drainage, diverting stoma, epiplooplasty. Even if many studies and articles have focused on colorectal anastomotic leakage prevention in rectal cancer surgery data regarding this topic in the setting of endometriosis where lacking. Due to major differences between the two situations, patients, diseases the use of the conclusions from the literature have to be taken with caution. In 4 randomized controlled trials the usefulness of systematic postoperative pelvic drainage hasn\'t been demonstrated. As this practice is not systematically recommended in cancer surgery, its interest is not demonstrated after colorectal resection for endometriosis. There is a heavy existing literature supporting systematic diverting stoma creation after low colorectal anastomosis for rectal cancer. Keeping in mind the important differences between the two situations, the conclusions cannot be directly extrapolated. In endometriosis surgery after low rectal resection, stoma creation must be discussed and the patient must be informed and educated about this possibility. Even if widely used there is no data supporting the role of epiplooplasty in colorectal anastomotic complication prevention? The place for epiplooplasty in preventing rectovaginal fistula occurrence in case of concomitant resection hasn\'t been studied.

International guidelines on the prevention and treatment of parastomal hernias are lacking. The European Hernia Society therefore implemented a Clinical Practice Guideline development project.
The guidelines development group consisted of general, hernia and colorectal surgeons, a biostatistician and a biologist, from 14 European countries. These guidelines conformed to the AGREE II standards and the GRADE methodology. The databases of MEDLINE, CINAHL, CENTRAL and the gray literature through OpenGrey were searched. Quality assessment was performed using Scottish Intercollegiate Guidelines Network checklists. The guidelines were presented at the 38th European Hernia Society Congress and each key question was evaluated in a consensus voting of congress participants.
End colostomy is associated with a higher incidence of parastomal hernia, compared to other types of stomas. Clinical examination is necessary for the diagnosis of parastomal hernia, whereas computed tomography scan or ultrasonography may be performed in cases of diagnostic uncertainty. Currently available classifications are not validated; however, we suggest the use of the European Hernia Society classification for uniform research reporting. There is insufficient evidence on the policy of watchful waiting, the route and location of stoma construction, and the size of the aperture. The use of a prophylactic synthetic non-absorbable mesh upon construction of an end colostomy is strongly recommended. No such recommendation can be made for other types of stomas at present. It is strongly recommended to avoid performing a suture repair for elective parastomal hernia. So far, there is no sufficient comparative evidence on specific techniques, open or laparoscopic surgery and specific mesh types. However, a mesh without a hole is suggested in preference to a keyhole mesh when laparoscopic repair is performed.
An evidence-based approach to the diagnosis and management of parastomal hernias reveals the lack of evidence on several topics, which need to be addressed by multicenter trials. Parastomal hernia prevention using a prophylactic mesh for end colostomies reduces parastomal herniation. Clinical outcomes should be audited and adverse events must be reported.

BACKGROUND: Mechanical bowel obstruction in rectal cancer is a common problem, requiring stoma placement to decompress the colon and permit neo-adjuvant treatment. The majority of patients operated on in our hospital are referred; after stoma placement at the referring centre without overseeing final type of surgery. Stoma malpositioning and its effects on rectal cancer care are described.
METHODS: All patients who underwent surgery for locally advanced or locally recurrent rectal cancer between 2000 and 2013 in our tertiary referral centre were reviewed and included if they received a stoma before curative surgery. Patients with recurrent rectal cancer were only included if the stomas from the primary surgery had been restored. The main outcome measures are stoma malpositioning, postoperative and stoma-related complications.
RESULTS: A total of 726 patients were included; of these, 156 patients (21%) had a stoma before curative surgery. In the majority of patients, acute or pending large bowel obstruction was the main indication for emergent stoma creation; some of the patients had tumour-related fistulae. In 53 patients (34%), the stoma required revision during definitive surgery. No significant differences were found regarding postoperative complications.
CONCLUSIONS: One-third of the previously placed emergency stomas were considered to be located inappropriately and required revision. We were able to avoid increased complication rates in patients with a malpositioned stoma, however unnecessary surgery for an inappropriately placed stoma should be avoided to decrease patient inconvenience and risks. An algorithm is proposed for the placement of a suitable stoma.
