A case in which a Naturfit stent was useful for malignant ileocecal stenosis

Abstract

A 91-year-old woman with primary complaints of abdominal pain and vomiting visited our hospital. Abdominal computed tomography revealed an ileocecal tumor with ileal dilation (Figure 1a). Colonoscopy (PCF‐Q260AZI; Olympus, Tokyo, Japan) revealed a circumferential cecal tumor invading the ileocecal valve (Figure 1b). A biopsy revealed adenocarcinoma, which was diagnosed as ileocecal cancer, resulting in obstruction. Surgery was deemed difficult due to her dementia and bedridden status. We placed a palliative colonic self-expandable metal stent (SEMS), with informed consent from her family. A 0.035-inch guidewire (JagwireTM, Boston Scientific Japan, Tokyo, Japan) was advanced to the ileum side, and an endoscopic retrograde cholangiopancreatography catheter was inserted through the guidewire to perform gastrografinography. The stenosis had flexion and was 60 mm in length. We selected HANAROSTENT NaturfitTM (22 mm × 9 cm, M. I. Tech, Seoul, Korea), as this could be placed with the side inside the large intestine (Figure 2a, c). We confirmed that the stent was patent and did not deviate by X-ray (Figure 2b, d). The patient was able to resume eating immediately and remains asymptomatic after three months.
