Preoperative stoma site marking for fecal diversions (ileostomy and colostomy): position statement of the Canadian Society of Colon and Rectal Surgeons and Nurses Specialized in Wound, Ostomy and Continence Canada
Bibliographic record
Abstract
BACKGROUND: Every year, about 13 000 Canadians undergo an ostomy procedure, which requires stoma site marking to create a well-constructed stoma and prevent stoma-related complications. The Canadian Society of Colon and Rectal Surgeons (CSCRS) and Nurses Specialized in Wound, Ostomy and Continence Canada (NSWOCC) created a position statement to provide evidence-based guidance and techniques for stoma site selection. METHODS: A task force was formed comprising 20 health care professionals (7 colorectal surgeons from the CSCRS and 13 nurses from NSWOCC) with representation from across Canada. A literature review was performed, with the following databases searched from January 2009 to April 2019: MEDLINE, Embase, Cochrane, PubMed, CINAHL and Google Scholar. After the abstracts were screened, 6 task force members created a draft version of the position statement from the articles retained after full-text review. The draft was submitted to the entire task force for comments, and the ensuing modifications were incorporated. Peer reviewers were then recruited from the CSCRS and NSWOCC; a summary of their comments was reviewed by the task force, and modifications were incorporated to produce the final document. RESULTS: The literature search identified 272 papers, of which 58 were reviewed after duplicates were excluded. After full-text review, 18 papers were included to guide the position statement. From these papers, we created a series of 17 steps for stoma site marking. Four general principles were found to be important for stoma site marking: obtain informed consent, identify important patient factors and landmarks, assess the abdomen and mark the most appropriate location. A 1-page enabler document and video were created as teaching aids and to help with dissemination of the information. CONCLUSION: This position statement, associated enabler document and video provide evidence-based guidance for stoma site marking in both emergency and elective settings, and should be used by surgeons and nurses specialized in wound, ostomy and continence to identify optimal stoma sites preoperatively.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
