Gastric inflammatory fibroid polyp treated by endoscopic submucosal dissection

Area of Science:

• Gastroenterology
• Surgical Oncology
• Pathology

Background:

• Gastric submucosal tumors (GSTs) are a diverse group of neoplasms arising from the gastric wall.
• While many GSTs are benign, malignant potential necessitates accurate diagnosis and appropriate management.
• Endoscopic submucosal dissection (ESD) is an advanced endoscopic technique for resecting early gastrointestinal cancers and large non-neoplastic lesions.

Observation:

• A 64-year-old male presented with a gastric submucosal tumor located in the anterior wall of the gastric antrum.
• The lesion measured 25 mm in diameter and demonstrated growth.
• Endoscopic examination was performed for evaluation and management.

Findings:

• Complete resection of the gastric submucosal tumor was achieved using endoscopic submucosal dissection (ESD).
• Histopathological analysis confirmed the diagnosis of an inflammatory fibroid polyp (IFP).
• The IFP measured 25 mm, and the resection margins were clear.

Implications:

• ESD is demonstrated as a safe and effective therapeutic modality for gastric submucosal tumors, including IFPs.
• This minimally invasive approach avoids the need for formal surgical gastrectomy for selected submucosal lesions.
• Further research into ESD for various types of GSTs can refine treatment guidelines and improve patient outcomes.
