Abstract
BACKGROUND

Solitary hamartomatous polyps (SHPs) are rare lesions. Endoscopic full-thickness resection (EFTR) is a highly efficient and minimally invasive endoscopic procedure that benefits from complete lesion removal and high safety.

CASE SUMMARY

A 47-year-old man was admitted to our hospital after experiencing hypogastric pain and constipation for over fifteen days. Computed tomography and endoscopy revealed a giant pedunculated polyp (approximately 18 cm long) in the descending and sigmoid colon. This is the largest SHP reported to date. Having considered the condition of the patient and mass growth, the polyp was removed using EFTR.

CONCLUSION

On the basis of clinical and pathological evaluations, the mass was considered an SHP.

Core Tip: Solitary hamartomatous polyps (SHPs) are rarely encountered and seldom reported in the literature. Most SHPs occur in the stomach and small intestine. An SHP in the descending colon has not been reported previously. In this report, we describe a giant pedunculated polyp, approximately 18 cm long, diagnosed as an extensively pedunculated giant SHP. We successfully resected this polyp using endoscopic full-thickness resection, which provides a viable option for the clinical resection of giant pedunculated polyps.
