Evaluating the Efficacy of Suture Mesh vs. Planar Mesh in Ventral Hernia Treatment

The goal of this clinical trial is to investigate whether mesh-suture affects wound complication rates, patient-reported quality of life, and operation time in adult patients undergoing surgery for small ventral hernias. The main questions it aims to answer are: Does mesh-suture reduce wound complication rates compared to planar mesh? Does mesh-suture improve patient-reported quality of life(QoL) and affect operation time compared to planar mesh? Comparison group: Researchers will compare standard treatment with planar mesh to the interventional treatment with mesh-suture to see whether mesh-suture leads to fewer complications, better quality of life, and shorter operation time. Participants will: Be randomized to receive either planar mesh or mesh-suture during hernia repair surgery. Undergo standardized preoperative assessment, including baseline data and QoL scoring. Attend a postoperative visit on day 7-13 for wound inspection and ultrasound. Complete QoL assessments at 90 days (telephone follow-up). Have operation time recorded and medical records reviewed for readmissions within 90 days.

Comparison of Onlay Mesh Repair and Sublay Mesh Repair in Umbilical Hernia Surgery

Umbilical hernia is a common condition that is frequently treated with surgical mesh repair to reduce recurrence rates. Among the commonly used techniques, onlay mesh repair and sublay mesh repair are widely performed; however, there is ongoing debate regarding their comparative effectiveness and safety. The aim of this study is to compare onlay mesh repair and sublay mesh repair in patients undergoing elective umbilical hernia surgery, with respect to postoperative complications, recurrence rates, operative outcomes, and length of hospital stay. By evaluating clinical outcomes associated with each technique, this study seeks to contribute evidence to guide the selection of the most appropriate surgical approach for umbilical hernia repair.

The PAPYRUS Study: Permanent vs. Absorbable Sutures in PrimarY Repair of Umbilical HerniaS: A Multicentre, Single-blind, Non-inferiority, Randomized Controlled Trial

Umbilical hernias can be found in over a quarter of the population and comprise of 15% of hernia repairs performed in Canada. While mesh repair is commonly used for larger hernias, smaller hernia defects are often closed with sutures alone. While non-absorbable sutures may have greater tensile strength, the use of absorbable sutures has been found to reduce the risk for wound infection and improve healing. The objective of this multi-centre, nationwide randomized controlled study is to determine whether there is a difference in hernia recurrence when the repair is completed with absorbable polydioxanone suture versus permanent polypropylene suture. The study will also explore post-operative complications and quality of life. Recruitment will take place over 5 years with follow-up at the 30-day, 12-month and 24-month mark following surgery. The results of this trial will be directly applicable to national and international hernia guidelines and will impact the care of thousands of patients.
