BACKGROUND
The concept of macroscopic on-site evaluation (MOSE) was introduced in 2015 when the endoscopist observed better diagnostic yield when the macroscopically visible core on MOSE was superior to 4 mm. Recent studies suggest that MOSE by the endoscopist may be an excellent alternative to rapid on-site evaluation, and some classifications hav...

The gallbladder (GB) is a susceptible organ, prone to various pathologies that can be identified using different imaging techniques. Transabdominal ultrasound (TUS) is typically the initial diagnostic method due to its numerous well-established advantages. However, in cases of uncertainty or when a definitive diagnosis cannot be established, comput...
Background and aims
Endoscopic ultrasound-guided tissue acquisition, including both fine-needle aspiration (EUS-FNA) and fine-needle biopsy (EUS-FNB), has been frequently performed to acquire samples from both pancreatic and non-pancreatic lesions. Still, the impact of the diagnostic yield between FNA and FNB is uncertain. We conducted this study t...

Fishbones are frequently swallowed by foreign objects that can penetrate the gastrointestinal tract. Nonetheless, it is quite uncommon for these fishbones to become lodged within the tract, resulting in the formation of foreign body granulomas that resemble submucosal tumors. When encountering this situation, it's important to consider differential...

Background:
Almost half of the patients with colorectal cancer (CRC) will experience local-regional recurrence after standard surgical excision. Many local recurrences of colorectal cancer (LRCC) do not grow intraluminally, and some may be covered by a normal mucosa so that they could be missed by colonoscopy. Early detection is crucial as it offe...
