Surgery Clinical Trial

Official title: Global Cohort Study: Hernias, Pathway and Planetary Outcomes for Inguinal Hernia Surgery

Status Recruiting

Clinical Trial Summary

The primary aim of the HIPPO study is to identify compliance to audit standards (pre-operative and intraoperative) standards for the repair and management of inguinal hernia. A prospective, multicentre, cohort study will be delivered by NIHR Unit on Global Surgery globally. Mini-teams of up to five collaborators per data collection period will prospectively collect data over a continuous 28-day period at each participating centre. This will be on consecutive patients undergoing elective and/or emergency primary inguinal hernia surgery, with follow-up to 30 postoperative days.

Clinical Trial Description

Inguinal hernia surgery is one of the most common elective operations around the world. It was significantly down-prioritised during the pandemic, with fewer planned procedures and a likely increase in a global backlog. According to the most updated data, there are 74,822 patients waiting for inguinal hernia repair in the United Kingdom's National Health Service (NHS), although the recommended expected waiting time should not exceed 18 weeks. It is likely that other countries face the same problem, although such granular data does not exist. Additionally, while waiting for an elective repair, complications of inguinal hernia might arise and an emergency surgery might be needed. Identifying the scale of the global backlog at a global level will inform policy makers on the best strategies to optimise this elective surgical pathway. Different surgical techniques exist, with different mesh and non-mesh techniques being described. The most up-to-date international guidelines recommend Lichenstein as the gold-standard for open repair of inguinal hernias, but a more tailored approach is recommended. The patient, the hernia type, and the surgeon's expertise will influence the choice of surgical technique which leads to a wide variation worldwide. Additionally, in areas where there is a deficit of surgeons, task sharing and task shifting might be implemented. Identification of this practice across the world and the outcomes associated with it will inform future research in this area. Finally, as inguinal hernia repair is a very common procedure, it can reflect the global uptake of environmentally sustainable measures in elective surgery. Achieving a net zero health system is only possible if reducing the carbon output from operating theatres is included. Different countries might have different protocols and measures adopted to be environmentally sustainable that could be used in different settings. Understanding the baseline point of these practices is extremely important to inform future studies in this area. ;
