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. High-Purity Type-I Collagen Scaffold: 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. Standard Peritonectomy Closure: Conventional Closure, to serve as the comparator arm for evaluating complication rates, adhesion formation, and recovery outcomes.

SECONDARY outcome

Timeframe: Baseline to 2 months after surgery

Change from baseline in quality of life assessed using the EORTC QLQ-C30 questionnaire. Scores are transformed to a 0-100 scale. For global health and functional scales, higher scores indicate better outcomes and higher change values represent improvement. For pain (symptom scales), higher scores indicate worse symptoms; therefore, reductions from baseline represent improvement
