Prospective, Multicenter, Randomized Controlled Phase III Trial of Biological Mesh for Alimentary Tract Reconstruction in Digestive Surgery
The goal of the Phase III clinical trial is to evaluate whether using a biological mesh helps improve the efficacy and safety of alimentary tract reconstruction surgery. In digestive surgery, bleeding or leakage at the surgical connection (anastomosis) remains a significant clinical challenge. This study explores whether reinforcing the anastomosis with a biological mesh can effectively reduce these risks and significantly enhance the reliability of the surgical procedure.
The main objectives of this study are:
To evaluate the effectiveness of the biological mesh in reducing bleeding points at the surgical site during the procedure.
To assess the role of the mesh in lowering the risk of postoperative complications, such as anastomotic leaks or stenosis, within 90 days after surgery.
Study Groups:
Experimental Group: Participants who undergo alimentary tract reconstruction with biological mesh reinforcement during surgery.
Control Group: Participants who undergo conventional surgical procedures without the use of mesh.
Participant Flow:
Participants will undergo a health evaluation before surgery to confirm they meet the study criteria. Following the procedure, participants will receive standard postoperative care and return for follow-up clinic visits 30 and 90 days after surgery to monitor their recovery.

Experimental: Experimental Group: Biological Mesh Reinforcement
Participants in this group will undergo alimentary tract reconstruction using a linear stapler with biological mesh reinforcement. During the procedure, researchers will record intraoperative raw data, including the number of bleeding points per unit length within 10 minutes after stapling, among other related clinical indicators. Following the surgery, participants will receive standard postoperative care. A 90-day monitoring period will be conducted to track anastomotic-related complications, specifically focusing on postoperative bleeding, leakage, stenosis, and other related conditions. |
A biological mesh specifically designed for reinforcement during alimentary tract reconstruction. It is used in conjunction with linear stapling devices during the surgical procedure to enhance the integrity of the anastomosis. The mesh provides mechanical support to the staple line, aiming to improve surgical outcomes by reducing intraoperative bleeding and the risk of postoperative complications, including leaks and stenosis, among other related conditions. |
|
Comparador Ativo: Control Group: Conventional Stapling
Participants in this group will undergo conventional alimentary tract reconstruction using a linear stapler alone. Identical intraoperative raw data regarding bleeding points and other related clinical indicators will be recorded for baseline comparison. Following the surgery, participants will receive standard postoperative care. Consistent with the experimental group, a 90-day monitoring period will track anastomotic-related complications, such as postoperative bleeding, leakage, stenosis, and other related conditions. |
Participants will undergo conventional alimentary tract reconstruction using a linear stapler alone, without the use of reinforcing mesh. |
