- A 54-year-old man was diagnosed with an esophageal duplication cyst after imaging revealed a large submucosal mass on the lower esophagus, which was asymptomatic but warranted surgical intervention due to potential future risks.
- Various imaging techniques, including contrast-enhanced computed tomography, esophagogastroduodenoscopy (EGD), and endoscopic ultrasonography (EUS), were used to confirm the diagnosis and assess the characteristics of the cyst.
- Histological examination showed the cyst was lined with muscle layers and epithelium, and while EUS fine-needle aspiration can aid in diagnosing similar lesions, it carries a risk of complications; hence, contrast-enhanced harmonic EUS was effectively used for noninvasive
A 78-year-old woman with hypertension had a positive fecal immunochemical test and underwent colonoscopy, which revealed a 4 mm sessile polyp (Paris type; 0-Is) in the transverse colon. Based on low magnification colonoscopy with narrow band imaging, the polyp was Type 2 according to the NBI International Colorectal Endoscopic classification, diagnosed as an adenoma, and then resected via cold snare polypectomy (CSP). Five days after CSP, she complained of right-sided abdominal pain.
