研究目的:

本研究旨在通过随机对照试验,评估猪源纤维蛋白粘合剂预防剖宫产术后子宫瘢痕憩室的疗效与安全性。主要比较两组术后6个月子宫剩余肌层厚度,并评估憩室形成率及临床症状改善情况。  

Objectives of Study:

This randomized controlled trial aims to assess the efficacy and safety of porcine fibrin sealant in preventing uterine scar diverticulum after cesarean section. The primary outcome is the residual myometrial thickness at 6 months post-operation, with secondary outcomes including diverticulum formation rate and improvement in clinical symptoms.
