Peristomal skin complications: what dermatologists need to know

Risk Prediction Model of Peristomal Skin Complications Among Patients with Colorectal Cancer and an Ostomy: A Cross-sectional Study in Shanghai, China

OBJECTIVE

To analyze the risk factors for peristomal skin complications (PSCs) in patients with colorectal cancer and an ostomy, construct a prediction model, and verify its effectiveness.

METHODS

In this cross-sectional study, researchers recruited 265 patients with an ostomy at the stoma clinic of a tertiary hospital, from May 2022 to August 2023. Patients were divided into two groups: complications group (n = 81) and no complications group (n = 184). Researchers constructed a logistic regression prediction model using univariate and multivariate analyses. From May 2023 to August 2023, a validation group of 135 patients with an ostomy was selected for external validation of the model.

RESULTS

The incidence of PSCs was 30.57% in the modeling group and 30.37% in the validation group. The predictor variables were preoperative and postoperative health education, tumor therapy within 3 months, preoperative stoma positioning, stoma height, stoma type, and excrement state. The Hosmer-Lemeshow test yielded a P value of .513, the area under the receiver operating characteristic curve was 0.872, the Youden index was 0.561, and the sensitivity and specificity were 0.827 and 0.734. For external validation, the Hosmer-Lemeshow test yielded a P value of .835, the area under the receiver operating characteristic curve was 0.887, and the sensitivity and specificity were 0.905 and 0.720, respectively.

CONCLUSIONS

The prediction model demonstrates good predictive efficacy and can serve as a reference for clinical caregivers in identifying patients at high risk of PSCs.

Peristomal skin lesions - identifying patients at risk

BACKGROUND AND OBJECTIVES

Diagnosis and therapy of peristomal skin lesions are challenging for the majority of therapists. Established diagnostic tools have not yet been validated. Our objective was to outline the spectrum of and to identify risk factors for skin lesions in ostomy patients. A focus was set on peristomal ulcerations and their differentiation as peristomal pyoderma gangrenosum.

METHODS

In a retrospective analysis, frequency and character of peristomal skin lesions in patients presenting at two departments were analysed. Patients suffering from peristomal ulcerations were subjected to a more detailed analysis including application of the PARACELSUS score.

RESULTS

A total of 565 patients with ostomy were analysed; 40.2% (n = 227) presented with peristomal skin lesions. Moisture-associated skin damage (27.9%) was the most common, while ulcerations (21.9%) and eczematous skin alterations (19.1%) were seen with comparable frequency. Peristomal pyoderma gangrenosum was diagnosed in 7.9% of all observed peristomal lesions. Among patients with inflammatory bowel disease (n = 98), peristomal ulcerations were the leading finding (35.7%), and pyoderma gangrenosum was more frequent in these patients (16.3%).

CONCLUSIONS

It is necessary to assess and classify peristomal skin lesions. Further studies for the validation of different scores or the development of diagnostic tools are needed.

Gastrointestinal Ostomies in Children: A Primer for the Pediatrician

Despite the advancement of medical therapies in the care of the preterm neonate, in the management of short bowel syndrome and the control of pediatric inflammatory bowel disease, the need to create fecal ostomies remains a common, advantageous treatment option for many medically complex children.

Development of a leakage impact assessment for patients with a stoma, who may be impacted by leakage

For people living with a stoma leakage is unpredictable. Despite advances in stoma products, leakage can lead to soiling and this, along with worrying about leakage, can significantly affect patients' everyday lives and impact their quality of life. It is also associated with excessive product use and increased healthcare resources. Leakage therefore remains a major unmet need for many people living with a stoma. To address this, Coloplast Ltd in collaboration with the authors and a broader group of stoma care nurses have worked together to develop a first version of the Leakage Impact Assessment. This assessment is intended to identify patients who struggle with leakage and leakage worry, and who might benefit from the reassurance that a new digital leakage notification system, Heylo™, can provide. This article reviews the evidence for leakage and its impact on people living with a stoma and outlines the development process for the assessment.

Potential of Cranberry Jelly to Prevent Urinary Stone Formation After Cutaneous Ureterostomy: A Case Report

One complication of cutaneous ureterostomy is urinary stone formation, which may lead to recurrent pyelonephritis. Frequent catheter changes and the prophylactic administration of antibiotics are commonly used to prevent stone formation. Cranberry products have been reported to inhibit stone formation in indwelling urethral catheters. We herein examined the inhibitory effects of a cranberry product on stone formation in a case of catheter occlusion due to stone formation after cutaneous ureterostomy. The results obtained indicate the potential of cranberry products to prevent stone formation after cutaneous ureterostomy requiring catheter placement.

Development, Validation, and Usability of the Chatbot ESTOMABOT to Promote Self-care of People With Intestinal Ostomy

This study aimed to describe the process of construction, validation, and usability of the chatbot ESTOMABOT to assist in the self-care of patients with intestinal ostomies. Methodological research was conducted in three phases: construction, validation, and usability. The first stage corresponded to the elaboration of a script through a literature review, and the second stage corresponded to face and content validation through a panel of enterostomal therapy nurses. In the third phase, the usability of ESTOMABOT was assessed with the participation of surgical clinic nurses, patients with intestinal elimination ostomies, and information technology professionals, using the System Usability Scale. The ESTOMABOT content reached excellent criteria of adequacy, with percentages of agreement equal to or greater than 90%, which were considered adequate, relevant, and representative. The evaluation of the content validity of the script using the scale content validity index/average proportion method reached a result above 0.90, and the Fleiss κ was excellent ( P < .05). The overall usability score of the chatbot was 81.5, demonstrating excellent usability. The script, developed and incorporated into the ESTOMABOT prototype, achieved satisfactory content validity. The usability of the chatbot was considered to be good, thereby increasing the credibility of the instrument.

Peristomal Pseudoverrucous Lesions: A Rare Skin Complication of Colostomy

A 56-year-old female patient with colostomy presented with skin-colored cobblestone and verrucous asymptomatic papules on her peristomal skin for three months; she was referred to dermatology. Histopathology revealed irregular acanthosis, tongue-like extension of rete ridges of mature squamous epithelium without atypical morphology, hyperkeratosis, and inflammation of the skin. The histopathologic appearance was evaluated as compatible with pseudoepitheliomatous hyperplasia. No signs of malignancy, fungus, or koilocytes were found. The lesions were diagnosed as pseudoepitheliomatous hyperplasia by clinical and histopathologic findings. In this case report, we review pseudoepitheliomatous hyperplasia associated with colostomy.

Cultural Adaptation and Validation of the Ostomy Skin Tool to the Brazilian Portuguese

PURPOSE

To adapt the Ostomy Skin Tool (discoloration, erosion, and tissue overgrowth) to the Brazilian culture and to analyze psychometric properties of the adapted version.

DESIGN

Psychometric (methodologic) evaluation of the instrument.

SUBJECTS AND SETTING

Three ostomy/enterostomal therapy nurses evaluated the extent and severity of peristomal skin conditions in a sample of 109 adults 18 years or older with peristomal skin complications. These participants were receiving care in an ambulatory care center in outpatient health services in Sao Paulo and Curitiba, Brazil. In addition, interobserver reliability was measured using a group of 129 nurse participants who attended the Brazilian Congress of Stomatherapy held from November 12 to 15, 2017, in Belo Horizonte, a city located in the state of Minas Gerais, Brazil. Nurse participants assessed the descriptions of peristomal skin complications of the Portuguese version, using the same photographs used in the original DET score, purposely placed out of original order.

METHODS

The study was performed in 2 stages. The instrument was translated into Brazilian Portuguese by 2 bilingual translators, and back-translated into English. The back-translated version was sent to one of the developers of the instrument for additional evaluation. During stage 2, content validity was evaluated by 7 nurses with expertise in ostomy and peristomal skin care. Convergent validity was evaluated by correlating the severity of peristomal skin complications to pain intensity. Discriminant validity was evaluated based on type and time of ostomy creation, presence of retraction, and preoperative stoma site marking. Finally, interrater reliability was evaluated using standardized photograph evaluation reproduced in the same sequence as the original English language version of the instrument, along with paired scores from assessment of adults living with an ostomy generated by an investigator and nurse data collectors.

RESULTS

The Content Validity Index for the Ostomy Skin Tool was 0.83. Levels of mild agreements were obtained for the nurses' observations in the evaluation of peristomal skin complications using standardized photographs (κ= 0.314). In contrast, moderate to almost perfect agreements were obtained when scores were compared in the clinical setting (κ= 0.48-0.93, according to the domains). Positive correlations between the instrument and pain intensity (r = 0.44; P = .001) indicate convergent validity of the adapted version of the Ostomy Skin Tool. In contrast, analysis of discriminant validity was mixed and definitive conclusions about this form of construct validity cannot be made based on this study.

CONCLUSION

This study supports convergent validity and interrater reliability of the adapted version of the Ostomy Skin Tool.

Assessment, diagnosis and treatment of peristomal skin lesions by remote imaging: An expert validation study

BACKGROUND

Prevention and treatment of peristomal skin problems should be a priority for nurses caring for ostomates, even when the assessment of lesions must be done remotely.

OBJECTIVE

To measure the level of agreement on assessment, diagnosis and care indications for peristomal skin lesions using remote imaging among nurses in Spain.

DESIGN

Prospective observational multicentre study to assess the diagnostic validity and inter- and intraobserver agreement between nurses in peristomal skin lesions. Data were collected between March and October 2019.

SETTINGS AND PARTICIPANTS

The research sample consisted of a group of 39 nurses with expertise in the care of ostomates.

METHODS

A panel of experts established a list of 24 common signs/findings, 15 diagnostic options and 35 treatment approaches for peristomal skin lesions. Three expert stoma therapy nurses compiled the clinical cases, which they described thoroughly and documented with photographs. The 39 participating nurses evaluated the cases in two rounds to measure inter and intraobserver agreement.

RESULTS

A high or very high level of agreement (κ > 0.61) was observed for the following signs: encrustation, nodules, mucocutaneous separation and varicose veins; for the following diagnoses: mucocutaneous dehiscence, allergic contact dermatitis, encrustation and varicose veins (caput medusae); for the following treatments: recommending a diet rich in vitamin C/blueberries, applying acetic acid dressings, applying cold and topical tacrolimus treatment.

CONCLUSIONS

The most easily identifiable lesions were those most prevalent and with visible signs. There was a lower level of agreement in identifying lesions for which photographs required additional information (laboratory data, description of signs and symptoms, type of diet and level of self-care). It is important to train nurses caring for ostomates to correctly describe ostomy-related lesions, which is important for nursing records, continuity of care and telehealth care.

A Consensus on Stomal, Parastomal, and Peristomal Complications

OBJECTIVE

To establish a consensus on terminology used to define stomal, parastomal, and peristomal complications in Australia.

METHODS

A list of stomal, parastomal, and peristomal complications was generated through group dialogue, which was informed by clinical and academic knowledge of the researchers. An extensive literature review was undertaken to identify any additional terms and to create a database of definitions/descriptions. A library of images related to the identified conditions was generated. An online Delphi process was conducted among a representative, purposive sample of Australia expert wound, ostomy, and continence nurses and colorectal surgeons. Ten terms were presented to the panel with descriptive photographs of each complication. Up to three Delphi rounds and, if necessary, a priority voting round were conducted.

RESULTS

Seven of the 10 terms reached agreement in the first round. One term ( allergic dermatitis ) was refined ( allergic contact dermatitis ) and reached agreement in the second round. Two terms ( mucocutaneous granuloma and mucosal granuloma ) were considered by the panel to be the same condition in different anatomical locations and were combined as one term ( granuloma ). Two terms ( skin stripping and tension blisters ) were combined as one term ( medical adhesive-related skin injury ) and reached agreement in round 2.

CONCLUSIONS

A consensus in terminology used to describe stomal or parastomal/peristomal complications will enhance communication among patients and health professionals and advance opportunities for education and benchmarking of stomal, parastomal, and peristomal complications nationally.

Perioperative Morbidity and Complications in Patients With an Established Ileostomy Undergoing Major Abdominal Surgery: A Retrospective Study

Background: Recently formed ileostomies may produce an average of 1,200 ml of watery stool per day, while an established ileostomy output varies between 600-800 ml per day. The reported incidence of renal impartment in patients with ileostomy is 8-20%, which could be caused by dehydration (up to 50%) or high output stoma (up to 40%). There is a lack of evidence if an ileostomy could influence perioperative fluid management and/or surgical outcomes. Methods: Subjects aged ≥18 years old with an established ileostomy scheduled to undergo an elective non-ileostomy-related major abdominal surgery under general anesthesia lasting more than 2 h and requiring hospitalization were included in the study. The primary outcome was to assess the incidence of perioperative complications within 30 days after surgery. Results: A total of 552 potential subjects who underwent non-ileostomy-related abdominal surgery were screened, but only 12 were included in the statistical analysis. In our study cohort, 66.7% of the subjects were men and the median age was 56 years old (interquartile range [IQR] 48-59). The median time from the creation of ileostomy to the qualifying surgery was 17.7 months (IQR: 8.3, 32.6). The most prevalent comorbidities in the study group were psychiatric disorders (58.3%), hypertension (50%), and cardiovascular disease (41.7%). The most predominant surgical approach was open (8 [67%]). The median surgical and anesthesia length was 3.4 h (IQR: 2.5, 5.7) and 4 h (IQR: 3, 6.5), respectively. The median post-anesthesia care unit (PACU) stay was 2 h (IQR:0.9, 3.1), while the median length of hospital stay (LOS) was 5.6 days (IQR: 4.1, 10.6). The overall incidence of postoperative complications was 50% (n = 6). Two subjects (16.7%) had a moderate surgical wound infection, and two subjects (16.7%) experienced a mild surgical wound infection. In addition, one subject (7.6%) developed a major postoperative complication with atrial fibrillation in conjunction with moderate hemorrhage. Conclusions: Our findings suggest that the presence of a well-established ileostomy might not represent a relevant risk factor for significant perioperative complications related to fluid management or hospital readmission. However, the presence of peristomal skin complications could trigger a higher incidence of surgical wound infections.

Factors predictive of optimal peristomal skin status in patients with an ostomy: a secondary analysis

Peristomal skin problems are common in ostomy patients and are connected to decreased quality of life and patient independence, as well as increased treatment costs. This study analysed the factors related to peristomal skin changes in order to better define the clinical profile of patients with optimal peristomal skin status. Secondary analysis of data from a nationwide, cross-sectional, retrospective, multicentre study performed in Spain (Uses and Attitudes in Ostomy) (Bueno Cruz et al, 2021) evaluated clinical data, including demographics, preoperative stoma site marking, type of ostomy, device used, frequency of leakage and scores from the Ostomy Skin Tool (OST) and quality of life (QoL) questionnaires. Risk factors for peristomal skin changes were analysed using multivariate analysis, and a predictive nomogram to anticipate optimal peristomal skin status (defined here as discolouration (D), erosion (E), and tissue overgrowth (T) (DET) score of 0) was developed. Some 871 patients with an ostomy using different commercial devices in Spain were evaluated. Multivariate analysis to predict optimal peristomal skin status revealed leakage frequency, patient age, type of ostomy, preoperative siting and type of baseplate used were independent predictors of peristomal skin status. Optimal peristomal skin care should be a treatment goal for nurse specialists in stomal therapy, and its individual influencing variables should be taken into account by nurses specialising in ostomy care.

The presurgical controlling nutritional status (CONUT) score is independently associated with severe peristomal skin disorders: a single-center retrospective cohort study

While nutritional interventions may potentially lower the risk of peristomal skin disorders (PSDs) and their exacerbation, no previous studies have evaluated the relationship between PSDs and nutritional status using the Controlling Nutritional Status (CONUT) score. The purpose of this study was to assess the impact of preoperative nutritional status on stoma health, and determine risk factors for postoperative PSDs, including severe PSDs. A retrospective analysis was performed of 116 consecutive patients with rectal cancer who underwent radical surgery with ileostomy or colostomy creation. PSDs were diagnosed in 32 patients (27.6%); including 10 cases (8.7%) that were defined as severe based on the ABCD-stoma score. Multivariable logistic regression showed that smoking (odds ratio [OR] 3.451, 95% confidence interval [CI] 1.240–9.607, p = 0.018) and ileostomy (OR 3.287, 95% CI 1.278–8.458, p = 0.014) were independent risk factors for PSDs. A separate multivariable logistic regression analysis of risk factors for severe PSDs, found that the only independent risk factor was the CONUT score (OR 10.040, 95% CI 1.191–84.651, p = 0.034). Severe PSDs are associated with preoperative nutritional disorders, as determined by the CONUT score. Furthermore, nutritional disorders may increase the severity of PSDs, regardless of the stoma type.

[How do patients manage their urostomy in everyday life? A questionnaire survey]

INTRODUCTION

The complications of stoma and peristomal are encountered by nearly 80% of patients within two years of surgery. The objective of this study was to evaluate the practical modalities of daily management of stoma and possible skin complications in a series of patients with non-continent urinary stoma.

METHODS

Monocentric study by questionnaires including all patients with non-continent urinary stoma between 2007 and 2019 in a French university center. The STOMA-QOL and a self-report questionnaire with 15 specific questions were used.

RESULTS

Among the 87 patients included in the analysis whose median age was 71 years, 57.5% used a 2-piece system, 69% used leg or thigh pockets, 74.7% were self-sufficient in emptying their stoma pockets. Autonomy on cutaneous support change was 38%. 62.1% of patients reported a peristomal skin event and 74.7% reported leaking stoma. In multivariate analysis, BMI>30, the presence of leaks and physical activity were significantly associated with the onset of peristomal skin events.

CONCLUSION

This study sheds light on the practical modalities of management of urinary stoma and the occurrence of skin complications related to stoma in terms of frequency and predisposing factors. The results obtained are likely to guide practitioners in the information of future operations and in the management of complications of urinary stoma.

Moisture-associated skin damage (MASD): A best practice recommendation from Wund-D.A.CH

Wund-D.A.CH., as the umbrella organization of German-speaking wound treatment societies, has currently developed a best practice recommendation for skin damage caused by body fluids, which is known as moisture-associated skin damage (MASD) in English-speaking countries. In this expert consensus, the diseases incontinence-associated dermatitis (IAD), intertriginous dermatitis, including intertrigo, gram-negative bacterial toe web infection and toxic contact dermatitis, including periwound and peristomal dermatitis are presented in a differentiated manner. A common feature of these clinical diseases is a deterioration of skin integrity due to prolonged exposure to body fluids such as urine, stool, sweat or wound exudate with associated physical-irritative and/or chemical irritation. In addition, other comorbidities and cofactors play an important role. The diagnosis of these interdisciplinary and interprofessionally relevant MASD is difficult in everyday clinical practice because there are currently no uniform definitions and many relevant differential diagnoses. Effective strategies for the prevention and therapy of these skin diseases are, for example, continence management, use of efficient, absorbent aids with good retention as well as consistent skin protection and adequate skin care. Another important aspect is the education of patients and relatives about the origin, treatment and prevention of MASD.

Risk factors for parastomal hernia of loop stoma and relationships with other stoma complications in laparoscopic surgery era

Background

Laparoscopic approach is now a widespread technique used worldwide, but there are few recent studies on risk factors for parastomal hernia. Therefore, this study was performed to analyze the incidence of parastomal hernia in laparoscopic and open surgery in which a loop stoma was created and was intended to be temporary, and to determine risk factors for parastomal hernia formation. Associations between parastomal hernia and other stoma-related complications were also analyzed.

Methods

A retrospective analysis of patient and surgical characteristics was performed in 153 consecutive patients who underwent a temporary diverting loop ileostomy or colostomy after surgery related to malignant diseases at our hospital from January to December 2016.

Results

Parastomal hernia developed in 77 cases (50.3%), including 39 (25.5%) diagnosed by physical examination and 38 (24.8%) detected by CT alone. On multivariate analysis, a stoma not passing through the middle of the rectus abdominis muscle was the only independent risk factor for parastomal hernia formation (p = 0.005) during the median follow-up of 245.0 days. When we analyzed the factors that were associated with a stoma not passing through the middle of the rectus abdominis muscle, the only independent factor associated with this misplacement of the stoma was a laparoscopic approach (p = 0.012). An analysis of stoma-related complications showed that peristomal skin disorders were significantly associated with parastomal hernia (p = 0.049).

Conclusions

This study showed that a stoma that is not formed through the middle of the rectus abdominis muscle is a risk factor for parastomal hernia formation, and that a laparoscopic approach is associated with this risk factor. Moreover, parastomal hernia is significantly associated with peristomal skin disorders.

Silicone-based adhesive removers for preventing peristomal skin complications caused by mechanical trauma

Peristomal skin complications (PSCs) are reported by 77% of people with a stoma, with a serious impact on their quality of life, as well as on healthcare resources. PSCs are usually caused by irritant contact dermatitis from stoma effluent or skin stripping from mechanical trauma to the stratum corneum caused by removal of the ostomy appliance. The risk of mechanical trauma is higher in neonates, young infants and older adults, who have more fragile, friable skin. The incidence and impact of PSCs can be reduced with an appropriate appliance change routine. Mechanical trauma is reduced by minimising the frequency of appliance changes and using an adhesive remover wipe or spray. In adults with a stoma, silicone-based solvents are considered the first choice, as they are skin-friendly and sting-free, and they release the adhesive from the skin quickly and evaporate within seconds, without leaving a residue. However, for neonates, wipes and specialist paediatric oil-based adhesive removers are advised instead. The efficacy of adhesive removers, and silicone-based solvents in particular, at maintaining skin integrity and reducing discomfort has been reported by both stoma care nurses and people with a stoma.

Peristomal Medical Adhesive-Related Skin Injury: Results of an International Consensus Meeting

Stomal and peristomal skin complications (PSCs) are prevalent in persons living with an ostomy; more than 80% of individuals with an ostomy will experience a stomal or peristomal complication within 2 years of ostomy surgery. Peristomal skin problems are especially prevalent, and a growing body of evidence indicates that they are associated with clinically relevant impairments in physical function, multiple components of health-related quality of life, and higher costs. Several mechanisms are strongly linked to PSCs including medical adhesive-related skin injuries (MARSIs). Peristomal MARSIs are defined as erythema, epidermal stripping or skin tears, erosion, bulla, or vesicle observed after removal of an adhesive ostomy pouching system. A working group of 3 clinicians with knowledge of peristomal skin health completed a scoping review that revealed a significant paucity of evidence regarding the epidemiology and management of peristomal MARSIs. As a result, an international panel of experts in ostomy care and peristomal MARSIs was convened that used a formal process to generate consensus-based statements providing guidance concerning the assessment, prevention, and treatment of peristomal MARSIs. This article summarizes the results of the scoping review and the 21 consensus-based statements used to guide assessment, prevention, and treatment of peristomal MARSIs, along with recommendations for research priorities.

Instrumentos de avaliação das complicações na pele periestoma: revisão integrativa

Objetivo: identificar y analizar las herramientas utilizadas para evaluar las complicaciones de la piel periestoma a través de revisión integradora de la literatura. Materiales y método: la búsqueda se dio en estas bases y portales de datos: Biblioteca Virtual de la Salud (BVS), PubMed/MEDLINE, CINAHL, Scopus y Web of Science, de enero a febrero de 2018. Durante la búsqueda en las bases de datos, se utilizaron los descriptores: ostomía, colostomía, dermatitis y las palabras clave: instrumentos, complicaciones de la piel periestoma y evaluación de la piel periestoma. Se incluyeron estudios que cumplieron los siguientes criterios: que estén disponibles en su totalidad, que estén publicados en español, inglés y portugués, no se tuvo en cuenta el rango de tiempo y tenía que ser acerca de las herramientas de evaluación de las condiciones de la piel periestoma. Resultados: el análisis identificó la existencia de nueve instrumentos con diferentes parámetros para describir la piel periestoma. En general, los instrumentos describen los cambios basados en la clasificación de la complicación, en la causa del daño a la piel o en las características clínicas presentes. Los estudios evidenciaron, además, que la mayoría de los instrumentos no poseen propiedades de medida probadas. Conclusión: de los nueve instrumentos de evaluación identificados, solo cuatro tienen propiedades de medidas probadas. El enfermero debe conocer los instrumentos existentes confiables y válidos para describir y clasificar la gravedad de los problemas de la piel periestoma, lo que aporta a la sistematización de un diagnóstico más preciso y mejora, por lo tanto, la calidad del cuidado.
