Objective:

To assess the efficacy of a perioperative intervention based on the Theory of Planned Behavior (TPB) in preventing lower extremity deep vein thrombosis (LEDVT) and improving postoperative outcomes in patients undergoing laparoscopic cholecystectomy (LC).

Approach:

• Study Design: Retrospective analysis of 136 gallstone patients undergoing LC, comparing conventional care and TPB-based intervention.
• Intervention: TPB-based intervention targeting attitudes, subjective norms, and perceived behavioral control through various preoperative and postoperative strategies.

Key Findings:

• Shorter times to first flatus, defecation, bowel sound recovery, first ambulation, and reduced hospital stay in the intervention group (P < 0.001).
• Lower complication rates, including LEDVT and pulmonary infection, in the intervention group (2.63% vs. 8.33%, P < 0.05).
• Improved coagulation profiles and lower anxiety/depression scores in the intervention group (P < 0.001).
• Higher health behavior scores in the intervention group (P < 0.001).

Interpretation:

The TPB-based perioperative intervention effectively accelerates recovery, reduces LEDVT and complications, optimizes coagulation, alleviates negative emotions, and enhances health behaviors.

Limitations:

• Retrospective design may introduce bias.
• Single-center study limits generalizability.

Conclusion:

The study supports the integration of TPB-based interventions into standard perioperative care for LC patients.
