Exploratory Study of Peristomal and Non-Peristomal Skin Barrier Characteristics in People With a Stoma (Stoma Imprint)

July 17, 2026 updated by: Salts Healthcare

An Exploratory Study of Peristomal and Non-Peristomal Skin Barrier Characterisation in People Living With a Stoma.

The purpose of this exploratory study is to obtain preliminary data on peristomal and non-peristomal skin barrier characterisation in people living with a stoma. The main questions it aims to answer are:

  • Is there a difference/similarity in skin barrier characterisation of peristomal and non-peristomal skin in people living with a stoma?
  • Is there a difference/similarity in peristomal skin barrier function of different stoma types (colostomy, ileostomy and urostomy)?
  • Does a stoma type/function, influence skin barrier characterisation of peristomal skin?

Participants will:

  • Attend a 1-hour study appointment
  • Undergo non-invasive skin procedures

Detailed Description

Healthy peristomal skin is vital, not only for stoma bag adherence and the prevention of leakages but for the stability to the skin barrier function. Peristomal skin refers to area surrounding a stoma and skin under the stoma bag adhesive. There is a lack of information and understanding on peristomal skin health and its skin barrier qualities. The study aims to gather data on peristomal and non-peristomal skin barrier characterisation in people living with a stoma. Participants enrolled in the study will undertake the following skin testing procedures:

  • Microbiome skin swabbing of peristomal and non-peristomal skin area
  • Skin profiles with Raman Spectrometer of the peristomal and non-peristomal skin
  • Biophysical skin property testing (skin damage, skin colour, redness, elasticity, sebum and pH) of the peristomal and non-peristomal skin

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assessment description of skin microbial composition of peristomal and non-peristomal skin
Time Frame: Study appointment (1 hour)
Each participant will provide four skin swab samples for microbiome profiling: two swabs from the peristomal (experimental) test site area and two swabs from the non-peristomal (control) test site area, on the opposite side of the abdomen. To Identify microbial species, present in peristomal and non-peristomal area using Metagenomic Shotgun Sequencing
Study appointment (1 hour)
Assessment of skin barrier chemical composition including water (mass-%), ceramides & fatty acids urea, lactate, protein, natural moisturising factors (NMF) and stratum corneum (SC) thickness of peristomal and non-peristomal skin
Time Frame: Study Appointment (1 hour)
6 High Wavenumber profiles of water (mass%) and SC thickness (Microns) and 6 Fingerprint profiles of ceramides & fatty acids urea, lactate, protein and natural moisturising factors (NMF) from peristomal skin (experimental) test site area and non-peristomal (control) skin test site area, using the Raman spectrometer
Study Appointment (1 hour)
Biophysical skin properties including Transepidermis water loss (TEWL), redness and skin colour, elasticity, sebum and pH of peristomal and non-peristomal skin
Time Frame: Study Appointment (1 hour)
Measurement of Transepidermal water loss (TEWL) with Tewameter, skin colour (melanin) and skin redness (erythema) with Mexameter, elasticity and firmness with Cutometer, sebum level with Subumeter and pH with pH Meter from peristomal area (experimental) skin test and non-peristomal (control) skin test area
Study Appointment (1 hour)
