Aim:
Parastomal hernia repair is a poorly evidenced area, with uncertainty around the optimum management. There is considerable heterogeneity within the patient cohort, and currently there is no standardization of patient descriptors in the reporting of parastomal hernia repair. The aim of this study was to develop a core descriptor set of key patient characteristics for patients undergoing surgical repair of a parastomal hernia for reporting in all parastomal hernia research.
Method:
A longlist of descriptors was generated from a review of the existing literature. The longlist was discussed with patients with lived experience of parastomal hernia repair. Colorectal, general and hernia surgeons took part in a three-round international modified Delphi process using a nine-point Likert scale to rank the importance of descriptors. Items meeting predetermined thresholds were included in the final set and discussed and ratified at the consensus meeting.
Results:
Seventy seven respondents completed round one, with 23 (29.8%) completing round three. Eighty six descriptors were rated across the three rounds, with 52 descriptors shortlisted. The consensus meeting ratified a final core descriptor set with 19 descriptors across eight domains: anatomy, contamination, disease, previous treatment, risk factors, symptoms, pathway and other hernia.
Conclusion:
The core descriptor set reflects characteristics that are important to surgeons when reporting on parastomal hernia repair. The use of this agreed core descriptor set may aid the reporting of future studies.
