Comparison of Ropivacaine-Poloxamer 407 Hydrogel and TAP Block for Postoperative Pain Management in Laparoscopic/Robotic Gastrectomy

Summary

This study aims to determine whether Ropivacaine-Poloxamer 407 hydrogel provides non-inferior pain control compared to TAP block for patients undergoing minimally invasive gastrectomy. The results will guide postoperative pain management practices and enhance recovery protocols for gastric cancer surgery.

3. Patients with an ASA (American Society of Anesthesiologists) score of 3 or below.
4. Patients aged 20 years or older.
5. Patients who have undergone laparoscopic or robotic gastrectomy

Exclusion Criteria:

1. Patients under 19 years of age.
2. Presence of ascites or peritoneal metastasis.
