What are the treatment options for gastric lipoma?

Gastric lipoma is a benign mesenchymal tumor of the stomach. It is rare, progresses slowly, rarely undergoes malignant transformation, and carries an excellent prognosis. Gastric lipomas predominantly occur in middle-aged adults, with no significant difference in incidence between males and females. These tumors may arise in the gastric body or antrum, but are most commonly found in the antrum. Approximately 90% originate in the submucosa and protrude into the gastric lumen, forming intragastric (intraluminal) lipomas; the remaining 10% develop in the subserosa and protrude outward into the peritoneal cavity, forming extragastric (extraluminal) lipomas. Below, we address the question: What are the treatment options for gastric lipoma?

What Are the Treatment Options for Gastric Lipoma?

Most gastric lipomas require no treatment. However, symptomatic lipomas can be surgically excised—either by local resection alone or by wedge resection including part of the gastric wall. In cases of multiple lipomas, partial gastrectomy may be considered.

If malignancy is suspected intraoperatively, rapid intraoperative frozen-section biopsy may be performed. The extent of surgical resection is then determined based on the histopathological findings and the degree of tumor invasion. In recent years, endoscopic resection has also been employed for polypoid gastric lipomas. Regardless of the approach selected, surgical intervention remains the definitive treatment.

Knowledge Expansion: How Should Gastric Lipoma Be Managed?

1. Small gastric lipomas can be removed via fiberoptic gastroscopy using electrocoagulation and snare techniques, resulting in minimal tissue damage and rapid patient recovery.

2. Most gastric lipomas can be treated with either laparoscopic surgery or conventional open surgery involving local excision.

3. If there is clinical or intraoperative suspicion of local malignant transformation, rapid intraoperative frozen-section analysis should be performed. If malignancy is confirmed, surgical resection should follow standard gastric cancer protocols—including extensive gastrectomy.

The above outlines the available treatment options for gastric lipoma. We hope this information is helpful to you.
