Prophylactic Mesh Reinforcement Versus Primary Closure After Emergency Midline Laparotomy (PREEMPT) (PREEMPT)
5 de agosto de 2026 actualizado por: Andrea Divizia, University of Rome Tor Vergata
PRophylactic mEsh Reinforcement Versus Primary Closure After Emergency Midline Laparotomy (PREEMPT): A Multicenter Randomized Clinical Trial
The PREEMPT trial is a multicenter randomized controlled trial comparing prophylactic onlay biosynthetic mesh reinforcement with primary suture closure in adult patients undergoing emergency midline laparotomy.
Participants will be randomized in a 1:1 ratio.
The primary endpoint is the incidence of incisional hernia at 1 year.
Secondary endpoints include postoperative complications, surgical site occurrences, pain, operative time, hospital stay, morbidity, mortality, quality of life, and long-term hernia incidence.

Descripción detallada
Incisional hernia (IH) is a frequent complication after midline laparotomy, with rates up to 50-70% in high-risk or emergency settings. Emergency procedures are particularly prone to IH due to contamination and suboptimal conditions. Prophylactic mesh reinforcement has been shown to significantly reduce IH rates in elective surgery without increasing wound morbidity, but evidence in emergency settings is scarce. Biosynthetic meshes, with favorable safety and cost profiles in contaminated fields, may offer an effective preventive strategy.
The PREEMPT trial is a multicenter, randomized (1:1) controlled study including adult patients undergoing emergency midline laparotomy. Eligible patients will be randomized to prophylactic onlay biosynthetic mesh reinforcement versus primary suture closure. The primary outcome is the incidence of incisional hernia at 1 year. Secondary outcomes include postoperative complications, surgical site occurrences, pain (VAS), operative time, length of hospital stay, 30-day morbidity and mortality, readmission and reoperation rates, and long-term quality of life (SF-36) and hernia incidence at 2 and 3 years.
The PREEMPT trial is a multicenter randomized clinical trial of patients undergoing emergency laparotomy. We aim to evaluate whether prophylactic bio-synthetic mesh reinforcement could reduce the incidence of incisional hernia in patients undergoing emergency midline laparotomy compared with primary suture closure.

|---|---|

Experimental: Mesh-repair group
Patients randomized to this arm will receive prophylactic onlay placement of a biosynthetic mesh (poly-4-hydroxybutyrate mesh) to reinforce the abdominal wall closure at the time of laparotomy closure, in addition to standard surgical closure.
A minimum overlap of 3 cm on all sides of the incision will be ensured.
Mesh fixation will be achieved with four sutures placed at the cardinal points only.
|
A biosynthetic mesh (poly-4-hydroxybutyrate mesh) is placed prophylactically to reinforce abdominal wall closure during laparotomy closure.
|
|
Comparador activo: Direct suture group
Patients randomized to this arm will receive standard abdominal wall closure according to European Hernia Society (EHS) guidelines: a slowly absorbable running suture will be used in all centers, employing a continuous small-bites technique.
Tissue bites of 5-9 mm from the wound edges will incorporate the aponeurosis only, with stitches placed 5 mm apart to ensure uniform tension distribution, aiming for a suture length to wound length ratio of at least 4:1.
