Background: Intraductal papillary mucinous neoplasm (IPMN) of the pancreas carries a risk of malignancy ranging from 15%-60%, depending on certain high-risk features. Diagnostic efforts often include radiographic imaging with computed tomography, magnetic resonance imaging, magnetic resonance cholangiopancreatography, and endoscopic ultrasound. Once IPMN has been diagnosed, the proposed indications for cyst resection are based primarily on size, main duct involvement, symptoms, and the presence of mural nodules. Diagnostic difficulty still remains, however, in patients with small lesions and with normal carcinoembryonic antigen levels, so alternative endoscopic modalities are needed.
Case Report: We report a case of intracystic SpyGlass Direct Visualization System (Boston Scientific) evaluation and biopsy of an IPMN in a 74-year-old male patient who presented to our surgical clinic with a history of chronic pancreatitis and significant weight loss during the last 2½ years.
Conclusion: In difficult diagnostic cases, SpyGlass pancreatoscopy can be quite useful because the device allows direct endoscopic visualization of the pancreaticobiliary ducts. Ductal pathology, including stones, strictures, and proliferative epithelial abnormalities, can be observed and even directly biopsied. Early experience in applying this technology to pancreatic cyst evaluation has indicated improved diagnostic accuracy.

An asymptomatic 79-year old woman presented with a 40 mm pancreatic cystic lesion, located in the pancreatic body-tail and consistent with branch-duct intraductal papillary mucinous neoplasm (BD-IPMN) without "high risk stigmata". During a 4-year follow-up period, imaging showed no mural nodules or main pancreatic duct dilation, and serum CEA and CA19.9 were within normal range.

Background: The authors assessed the feasibility, acceptability, and impact on cancer worry of a cancer screening program using multicancer early detection (MCED) tests and whole-body magnetic resonance imaging (WBM) in individuals at high cancer risk because of family history or germline variants in cancer-susceptibility genes.
Methods: This prospective trial enrolled participants aged 50 years and older who had a significant family history of cancer or a cancer-susceptibility gene variant. Participants underwent noncontrast WBM and MCED testing.

Background: Acute pancreatitis is an uncommon presentation of intraductal papillary mucinous neoplasm; however, it is considered a worrisome feature in current guidelines and can be an indication for surgery. There is controversy regarding its association with malignancy, and there is little information regarding the recurrence of pancreatitis after surgical resection.
Methods: We retrospectively reviewed patients who underwent resection for intraductal papillary mucinous neoplasm at a single institution between January 1990 and December 2023.

Background/objective: Patient-derived organoids (PDOs) have emerged as essential for ex vivo modelling for pancreatic cancer (PDAC) but reports on efficacy and organoid take rate are scarce. This study aimed to assess the feasibility of establishing PDOs from resected specimens in periampullary tumors.
Methods: Patients undergoing surgery for suspected periampullary cancer were included.
