A 66-year-old man underwent follow-up colonoscopy after colon polypectomy. The retroflexed view of the anal canal with white-light imaging revealed a whitish, slightly elevated lesion on the dentate line and an ill-defined flat lesion. A biopsy of the whitish elevation revealed squamous cell carcinoma (SCC), and endoscopic submucosal dissection (ESD) was planned. The lateral margin of the SCC was identified by spraying with Lugol's iodine, and the tumor was resected en bloc with no complications. The pathological findings were SCC in situ with parakeratosis in the whitish elevation and high-grade intraepithelial neoplasia in the ill-defined flat lesion, which exhibited a wide iodine-unstained area by chromoendoscopy...

Background and study aims  Colorectal polyps involving the appendiceal orifice (AO) are difficult to resect with conventional polypectomy techniques and therefore often require surgical intervention. These appendiceal polyps could potentially be removed with endoscopic full-thickness resection (eFTR) performed with a full-thickness resection device (FTRD). The aim of this prospective observational case study was to evaluate feasibility, technical success and safety of eFTR procedures involving the AO. Patients and methods  This study was performed between November 2016 and December 2017 in a tertiary referral center by two experienced endoscopists...

Adrenal cystic lesions constitute a rare finding and usually are diagnosed incidentally as retroperitoneal cysts during imaging studies. A major issue, especially for the large-sized ones, is their preoperative diagnosis and management, as imaging modalities often fail to detect their exact origin prior to surgery. We report a case of a big adrenal cyst that was mistakenly diagnosed and followed up as pancreatic cystic tail tumor. Our thorough workup, which included endoscopic ultrasound (EUS), managed to delineate an adrenal gland-originated cyst and altered further management of the patient...

Background and study aims  Capsule endoscopy(CE) is a well-established investigation for iron deficiency anemia (IDA) and melena, usually following negative upper and lower endoscopy. We aimed to study the effect of earlier CE in the investigative pathway for inpatients with IDA or melena at a large tertiary referral centre. Patients and methods  We analyzed inpatients undergoing CE for IDA or melena from 2005 to 2017, without signs/symptoms suggesting lower gastrointestinal tract pathology. Patients underwent CE following negative upper and lower gastrointestinal endoscopy (Group 1), or negative upper gastrointestinal endoscopy (UGIE) only (Group 2)...
