RESUMO
The oncogenic KRAS mutation is associated with increased tissue factor expression and thus hypercoagulability. In this regard, numerous studies published in the last decade have shown that KRAS mutations are an important risk factor for the development of thromboembolic phenomena in neoplasms of the digestive tract, such as colorectal cancer. On the other hand, some recently published studies suggest that KRAS mutations are also associated with an increased risk of developing thromboembolic phenomena in pancreatic cancer. Based on these premises, we have conducted a single-centre retrospective study on a cohort of patients with pancreatic cancer. Our aim is to demonstrate whether there is an association between the presence of KRAS mutations in our cohort of pancreatic cancer patients and an increased risk of developing thromboembolic phenomena.

According to some series, 0.3-1.5% of all cases of acute pancreatitis are drug induced. Acute pancreatitis due to levofloxacin is included in its safety data sheet as an adverse effect.

An 81-year-old man with mild iron deficiency anemia (Hb 12 g/dl) and a positive fecal occult blood test was referred for a colonoscopy. The patient was asymptomatic and not undergoing any treatment. A foreign body that crossed the colonic lumen and prevented the colonoscope progression was identified at 40 cm from the anal verge via colonoscopy. The object seemed to be hard and fixed when manipulated with biopsy forceps.
