Plain English summary of protocol

Background and study aims
A hernia can occur when a weak spot in the muscle or tissue lets an internal part of the body such as the intestines push through. An inguinal hernia occurs in the groin region when fatty tissue or a part of the bowel bulges through into your groin at the top of the inner thigh. When this happens on both sides of the groin it is called a bilateral inguinal hernia. Surgery can be used to push the bulge back into place and a surgical mesh is often used to strengthen the surrounding tissue. There are two types of mesh most often used in surgery to treat hernias. One is lightweight, and the other is heavyweight. The aim of this study is to see whether there is a difference in patients’ experience of pain and surgical complications depending on which type of mesh is used to treat their bilateral inguinal hernia.

Who can participate?
Adults over 18 undergoing surgery for bilateral inguinal hernia.

What does the study involve?
All participants are given a lightweight mesh and a heavyweight mesh. One mesh will treat one side of the hernia, and the other mesh will treat the other side; which side gets what mesh is allocated randomly. Questionnaires about pain and health related to the surgery are completed on the 1st, 3rd, 5th, and 7th day after surgery and, finally, one year after surgery.

What are the possible benefits and risks of participating?
Both type of meshes are approved and commonly used in medical practice and their use does not carry additional risk.

Where is the study run from?
The Santa Cristina University Hospital (Hospital Universitario Santa Cristina) (Spain)

When is the study starting and how long is it expected to run for?

Scientific titleRandomised clinical trial comparing low density versus high density meshes in patients with bilateral inguinal hernia
Study objectivesThere is a difference in patient-report of postoperative pain, feeling of a foreign body, postoperative complications, and recurrence of hernia in patients following surgery for bilateral inguinal hernia using either lightweight or heavyweight mesh.
Ethics approval(s)This study does not require ethics approval. We compare two meshes that are frequently used in inguinal hernia repair and these are approved for use.
Health condition(s) or problem(s) studiedBilateral inguinal hernia
InterventionLightweight mesh is randomly allocated to patients for use on one side of a bilateral hernia. The more frequently used heavyweight mesh is used on the other side. The side receiving the lightweight mesh is selected using a random numbers table.
Intervention typeProcedure/Surgery
Primary outcome measureOutcomes measured on 1st, 3rd, 5th and 7th postoperative day, and one year after surgery:
1. Postoperative pain measured by visual analogue scale
2. Complications following procedure comparing lightweight mesh and heavyweight mesh
3. Self-reported feeling of a foreign body following surgery
4. Recurrence of bilateral inguinal hernia comparing lightweight mesh and heavyweight mesh
Secondary outcome measuresThere are no secondary outcome measures.
