Prevalence of incidental clinically relevant pancreatic cysts at diagnosis based on current guidelines.

Background: Most pancreatic cysts (PCs) found incidentally by CT and MRI scans might not be clinically important according to the Fukuoka guidelines, the American Gastroenterological Association (AGA) guidelines and European guidelines.

Aims: To determine and compare the prevalence of incidental clinically important PCs (CIPCs).

Methods: Abdominal contrast-enhanced CT or MRI scans performed during a one-year period were retrospectively reviewed to identify incidental PCs.

Risk of Metachronous Advanced Neoplastic Lesions in Patients with Sporadic Sessile Serrated Adenomas Undergoing Colonoscopic Surveillance.

Objectives: The risk of developing metachronous advanced neoplastic lesions (ANLs) during surveillance after resection of sessile serrated adenomas (SSAs) has not been quantified.

Methods: Patients with sporadic SSAs resected between 1 April 2007 and 31 December 2009 who underwent surveillance colonoscopy in our institution were prospectively evaluated. Patients with low-risk adenomas (LRAs), high-risk adenomas (HRAs), and negative index colonoscopy (NIC) during the same period were identified using the pathology database and electronic medical records, and were also included as a comparison cohort.
