Aim:
To estimate the risk of venous thrombosis associated with pancreatic adenocarcinoma and its consequences on treatment and survival.
Patients And Methods:
We retrospectively analyzed a cohort of 90 patients (49 males, 41 females - median age: 67 years [range: 37-94]). Pancreatic adenocarcinoma was histologically proved in 72 patients (81%) and was metastatic in 49 patients (54.4%). A venous thrombosis was observed in 24 patients (26.7%). A pulmonary embolism occurred in 4 patients with 2 deaths. The risk of venous thrombosis was significantly reduced by the use of anti-thrombotic prophylaxis (HR: 0.03 [95CI: 0.003-0.27]) and increased among patients with a biological inflammatory syndrome (HR: 9.0 [95CI: 2.30-34.4]) and metastatic disease (HR: 4.4 [95CI: 1.1-17.9]). Overall survival was not different between patients with (6.6 months) or without (6.1 months) venous thrombosis.
Conclusion:
The risk of venous thrombosis is important and may delay the treatment in patients with advanced pancreatic carcinoma. Some patients with high risk of venous thrombosis may benefit from a prophylactic anticoagulant treatment.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
