Early- Versus Late-Onset Prosthetic Mesh Infection: More than Time Alone

Area of Science:

• Surgical innovation
• Medical device safety
• Infectious disease complications

Background:

• Ventral incisional hernia (VIH) repair commonly uses prosthetic mesh for effective outcomes.
• Mesh infection is a serious complication with a bimodal distribution (early and late onset).
• The distinct characteristics and implications of early versus late-onset mesh infections remain unclear.

Purpose of the Study:

• To investigate the differences between early- and late-onset prosthetic mesh infections following VIH repair.
• To analyze clinical manifestations, patient demographics, and quality of life in relation to infection timing.
• To explore potential differences in the pathophysiologic processes underlying early and late mesh infections.

Main Methods:

• A cohort study analyzed 102 patients undergoing VIH repair between January 2003 and September 2013.
• Data on risk variables were collected from electronic medical records at Jinling Hospital.
• Patient quality of life was assessed using the WHO Quality of Life-BREF questionnaire.

Main Results:

• Significant differences were observed between the early- and late-onset mesh infection groups.
• Variations were noted in clinical manifestations and descriptive analysis of the study population.
• Postoperative quality of life differed significantly between the early- and late-onset infection groups.

Conclusions:

• Early- and late-onset mesh infections following VIH repair exhibit distinct clinical features and impact on patient quality of life.
• These differences suggest potentially different underlying pathophysiologic mechanisms.
• Caution is advised with permanent prosthetic mesh use, and further long-term studies on intraperitoneal onlay mesh are warranted.
