Rare Causes of Gastrointestinal Bleeding: Focus on Pancreatic Pathology and Visceral Artery Aneurysms.

Chirurgia (Bucur) 2021 Dec;116(6 Suppl):S5-S15

Beside the common situations of upper gastrointestinal bleeding (GIB) managed by endoscopy, there are clinical situations when the endoscopic approach is limited by the amount of blood, the hemodynamic instability, the intermittent nature of bleeding and a proper diagnosis and treatment requires radiological interventional methods and even surgery. The pancreatic pathology is rarely considered as a possible cause for patients that presents in emergencies with GIB. The rupture of visceral artery aneurysms (VAAs), without underlying pancreatic pathology, should also be regarded in the differential diagnosis of GIB. Read More

Radiol Case Rep 2022 Mar 23;17(3):1013-1020. Epub 2022 Jan 23.

Department of Radiology, Robert Larner M.D. College of Medicine, University of Vermont Medical Center, 111 Colchester Ave, Burlington, VT 05401, USA.

Pancreatic pseudocyst formation, arterial pseudoaneurysm, and splanchnic vein thrombosis are complications of chronic pancreatitis that account for significant morbidity and mortality in this patient population. While the short-term utility of timely endovascular intervention for treating the vascular complications of chronic pancreatitis have been relatively well documented, there is a paucity of longitudinal follow-up in this patient population, therefore making it difficult to predict the long-term efficacy of these interventions. This report details a case of a gastroduodenal artery pseudoaneurysm embolization followed by symptomatic superior mesenteric vein chronic thrombosis treated by stent dilatation in a patient with chronic pancreatitis, with 7 years clinical and imaging follow-up.

Arterial Divestment and Resection in Post-neoadjuvant Pancreatic Adenocarcinoma.

Cureus 2021 Dec 8;13(12):e20275. Epub 2021 Dec 8.

Department of Gastrointestinal and General Surgery, Kathmandu Medical College Teaching Hospital, Kathmandu, NPL.

Introduction The advent of neoadjuvant therapy in the management of pancreatic adenocarcinoma has significantly improved the prognosis of the disease. Nevertheless, the only chance of long-term disease-free survival in pancreatic cancer is achieved with complete tumor resection, and artery involvement by the tumor is one of the major determinants in its resectability. We aim to evaluate the feasibility of a novel technique, namely, the periarterial divestment, which has allowed surgeons to clear the tumor tissues off the visceral arteries without the need for arterial reconstruction.
