- Colonic lipomas are benign tumors that usually don't cause symptoms, but those larger than 2 cm pose a higher risk of perforation during removal.

- All lipomas were successfully resected without complications, demonstrating that electrosurgical snare resection is a safe method when assisted by proper evaluation.

This study was undertaken to evaluate the accuracy and limitations of video type endoscopic ultrasound in preoperative staging of gastric cancer and assessing lymph node metastasis.
