Clinical Report: Impact of Body Mass Index on Perioperative Results Following Pancreaticoduodenectomy

Overview

This meta-analysis evaluates the impact of body mass index (BMI) on perioperative outcomes in patients undergoing pancreaticoduodenectomy (PD). Findings indicate that a BMI of ≥25 kg/m2 is linked to increased operative duration and blood loss, while a BMI of ≥30 kg/m2 is associated with a significant rise in perioperative mortality.

Background

Pancreaticoduodenectomy is a critical surgical intervention for pancreatic malignancies, yet it carries considerable risks of postoperative complications. Understanding the influence of BMI on surgical outcomes is essential for effective preoperative risk stratification and management.

Data Highlights

This study synthesized data from 25 studies, revealing that BMI categories significantly affect operative duration, blood loss, and postoperative complications.

Key Findings

• BMI ≥25 kg/m2 is associated with longer operative duration and increased blood loss.
• Higher BMI correlates with elevated risks of postoperative complications, including clinically relevant pancreatic fistula and delayed gastric emptying.
• BMI ≥30 kg/m2 is linked to a significant increase in perioperative mortality risk.
• Operative complexity increases progressively with rising BMI.
• No notable association was found between BMI and long-term overall survival.

Clinical Implications

BMI should be considered in preoperative assessments to better predict surgical risks and outcomes.

Conclusion

The study highlights the importance of BMI in influencing perioperative outcomes following PD.
