Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This dual-centre, randomized controlled trial evaluates the safety and efficacy of high-purity Type-I collagen-based biomaterial, as a peritoneal substitute following peritonectomy in patients undergoing cytoreductive surgery (CRS) for peritoneal surface malignancy. The study tests whether Surgicoll-Mesh can reduce major postoperative intra-abdominal complications compared with standard management.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Peritonectomy during CRS often leads to adhesion formation, obstruction, and wound complications. High-purity Type-I collagen-based biomaterial, a resorbable collagen matrix, provides a temporary barrier and scaffold that promotes tissue regeneration and reduces adhesions. This trial will randomize 60 patients (30 per group) to receive standard closure or peritoneal reconstruction with high-purity Type-I collagen-based biomaterial. The primary endpoint is the incidence of major intra-abdominal complications within 2 months. Secondary endpoints include individual complication rates, bowel recovery, hospital stay, mesh-related events, and quality of life

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

High Purity Type-I Collagen-based Peritoneal Substitute

Patients undergoing cytoreductive surgery (CRS) with peritonectomy will receive intraoperative peritoneal reconstruction using High Purity Type-I Collagen-based Peritoneal Substitute, a sterile, resorbable, high-purity Type-I collagen biomaterial. The mesh is tailored to the peritonectomy defect and secured with absorbable sutures prior to abdominal closure.

Group Type ACTIVE_COMPARATOR

High-Purity Type-I Collagen Scaffold

Intervention Type DEVICE

Peritoneal reconstruction using High-Purity Type-I Collagen Scaffold after peritonectomy. Purpose is to act as a biologic peritoneal substitute promoting tissue regeneration and reducing postoperative adhesions and complications.

Standard Peritonectomy Closure

Patients undergoing cytoreductive surgery with peritonectomy will have standard closure of the peritoneal defect without the use of any biomaterial or mesh substitute. Surgical closure will follow institutional standard of care.

Group Type ACTIVE_COMPARATOR

Standard Peritonectomy Closure

Intervention Type PROCEDURE

Conventional Closure, to serve as the comparator arm for evaluating complication rates, adhesion formation, and recovery outcomes.
