Abstract

Background: Abdominal surgery sometimes necessitates creating a stoma, which can cause future complications including parastomal hernia (PSH), an incisional hernia, adjacent and related to the stoma. PSH affects approximately 40% of patients within two years of stoma formation. Complications of PSH reduce patients’ quality of life and can be severe, e.g. bowel obstruction. PSH
are difficult to manage and can recur after surgical repair. Therefore, it is very important to prevent a PSH. Surgeons create stomas in different ways and both patient and surgical factors are believed to influence the development of PSH. The CIPHER study has been designed to investigate the influence of different surgical techniques on PSH development.

Method: The CIPHER study aims to recruit 4000 patients undergoing elective or expedited surgery with the intention to form an ileostomy or colostomy, irrespective of the primary indication for the planned surgery. For each patient, surgeons describe their methods of trephine formation, mesh reinforcement of the stoma trephine, use of the stoma as specimen extraction site and closure of wounds. The primary outcome is incident PSH during follow-up defined as symptoms of PSH (custom-designed questionnaire) and anatomical PSH, ascertained by independent reading of usual care CT scans. Secondary outcomes include; surgical site infection, Comprehensive Complication Index, quality of life (EQ-5D-5L and SF-12), PSH repair and use of NHS resources.

Discussion: The CIPHER study is the first to investigate detailed surgical methods of stoma formation, in a large, representative cohort of patients with range of primary indications, both cancer and noncancer.

Bibliographical note

Funding Information:
The CIPHER study is funded by the NIHR Health Technology Assessment (HTA) Programme (grant ref. 14/166/01). The development work for the questionnaire and methods for understanding surgical techniques were funded by the MRC Hub for Trials Methodology Research in Bristol (ConDuCT‐II Hub). The study sponsor is the Royal Devon and Exeter NHS Foundation Trust and the study is managed by the Clinical Trials and Evaluation Unit, Bristol Trials Centre, Bristol. The CIPHER study is overseen by an independent study steering committee. The study has been designed with input from public and patient groups who fed back comments on the study protocol and reviewed patient‐facing documentation. The study is supported by Colostomy UK and the Ileostomy Association. The study is conducted in compliance with General Data Protection Regulations and Good Clinical Practice.
