Management of Postoperative Drainage and Wound Complications After Lower Limb Soft Tissue Tumor Resection

Overview

This retrospective study analyzed postoperative drainage therapy and wound complications following primary resection of lower extremity soft tissue tumors. It identified drainage volume on the second postoperative day as a strong predictor for complicated wound courses, enabling early detection and intervention to improve patient outcomes.

Background

Complete surgical resection is central to multimodal therapy for lower extremity soft tissue tumors, but postoperative complications such as lymphatic leakage, hemorrhage, and infection are common and can delay adjuvant therapy. Reported wound complication rates vary widely, partly due to heterogeneous definitions. Standard care typically involves direct wound closure with intraoperative drain placement, yet no uniform guidelines exist for postoperative wound management in this context. Early identification of wound healing disorders is critical for timely treatment and improved quality of life.

Data Highlights

Key Findings

• Postoperative wound complications after lower limb soft tissue tumor resection occur in 17.6% to 48% of cases.
• Major wound complications are defined by the need for surgical intervention, inpatient antibiotic treatment, or conservative wound management with procedures like drain reinsertion.
• Direct wound closure with intraoperative drain placement remains the standard surgical approach.
• Drainage volume measured on the second postoperative day is a reliable early predictor of complicated wound healing (AUC = 0.897).
• Early identification of patients at risk allows timely initiation of appropriate treatments to reduce prolonged hospitalization and improve outcomes.

Clinical Implications

Monitoring drainage volume on postoperative day two can serve as a simple, objective clinical measure to identify patients at risk for complex wound healing complications. This enables clinicians to initiate early interventions, potentially reducing hospital stay duration and facilitating timely transition to adjuvant therapies. Standardizing postoperative wound management protocols may improve patient quality of life and oncological outcomes.

Conclusion

This study highlights the importance of postoperative drainage monitoring as a predictive tool for wound complications after lower extremity soft tissue tumor resection. Implementing early detection strategies based on drainage volume can optimize patient care and improve surgical outcomes.
