Clinical Scorecard: Guided Puncture Techniques for Distinguishing Between Malignant and Benign Peritoneal Lesions: A Systematic Review and Meta-Analysis
At a Glance
Category
Detail
Condition
Benign and malignant peritoneal lesions
Key Mechanisms
Image-guided puncture (US, CT, EUS) to obtain tissue samples for pathological differentiation
Target Population
Patients with peritoneal lesions requiring differentiation between benign and malignant etiologies
Care Setting
Diagnostic imaging and interventional radiology settings, minimally invasive outpatient or inpatient procedures
Key Highlights
Peritoneal lesions include benign conditions like tuberculous peritonitis and malignant diseases such as metastatic cancer.
Conventional imaging modalities often cannot reliably differentiate benign from malignant peritoneal lesions due to overlapping features.
Image-guided puncture is a safe, minimally invasive, and highly sensitive diagnostic alternative to traditional surgical biopsy.
Guideline-Based Recommendations
Diagnosis
Use image-guided puncture techniques (US, CT, EUS) to obtain biopsy samples for pathological confirmation.
Confirm diagnosis with postoperative pathology and/or diagnostic laparoscopy as reference standards.
Management
Prefer image-guided puncture over laparotomy or diagnostic laparoscopy to reduce patient morbidity and risk of tumor dissemination.
Select puncture modality based on lesion accessibility and imaging availability.
Monitoring & Follow-up
Monitor for procedure-related complications such as infection or bleeding post-puncture.
Evaluate diagnostic accuracy through sensitivity and specificity metrics in clinical follow-up.
Risks
Potential risks include infection and tumor dissemination, though these are lower compared to surgical biopsy.
False negatives and false positives may occur; sensitivity ranges from 64% to 98%, specificity from 86% to 100%.
Patient & Prescribing Data
Patients undergoing evaluation for peritoneal lesions suspicious for malignancy
Image-guided puncture provides a minimally invasive diagnostic option with high sensitivity and specificity, reducing the need for more invasive surgical procedures.
Clinical Best Practices
Conduct thorough imaging evaluation prior to puncture to guide biopsy site selection.
Use standardized protocols for image-guided puncture to optimize tissue yield and diagnostic accuracy.
Apply QUADAS-2 tool for quality assessment of diagnostic studies to ensure reliability of results.
Employ random-effects meta-analysis models to account for study heterogeneity in diagnostic performance evaluation.
