Splenic arterial aneurysms (SAA) are rare and are usually atherosclerotic and/or related to pregnancy. Because pregnancy is the most important predisposing factor, the strong predilection of SAA for women is not surprising. The authors report a case of SAA rupture in a man with
chronic pancreatitis
as the predisposing factor. A 56-year-old man with abdominal pain and hematemesis was resuscitated and underwent endoscopy, but he died 18 hours later of massive hematemesis before definitive surgery could be carried out. At autopsy, there was
chronic pancreatitis
with fibrous adhesions tethering the tail of the pancreas, spleen, and posterior wall of the stomach together. The SAA was indented into the posterior wall of the stomach, into which it had ruptured from without. He also had alcoholic cirrhosis but no esophageal varices or conventional gastric ulcers. Other important predisposing factors such as abdominal trauma, infective
endocarditis
, polyarteritis nodosa, and segmental medial arteriopathy were absent. Histologic examination confirmed the rupture of the SAA. The SAA had Monckeberg medial calcinosis but little evidence of atherosclerosis. The well-documented complications of acute and
chronic pancreatitis
include shock, abscess, pseudocyst formation, and duodenal obstruction. This report describes the rare complication of SAA rupture, which may be fatal.

Host-derived factors alter gut microenvironment, and changes in gut microbiota also affect biological functions of host. Alterations of gut microbiota have been reported in a wide variety of diseases, but the whole picture of alterations in pancreatic diseases remains to be clarified. In particular, the gut microbiota may be affected by malnutrition or impaired exocrine pancreas function that is associated with pancreatic diseases. We here conducted comprehensive analysis of gut microbiota in patients with type 1 autoimmune pancreatitis (AIP), a pancreatic manifestation of the systemic IgG4-related disease, and
chronic pancreatitis
(CP). The two diseases were selected, because altered immune reactions in AIP and/or long-standing malnutrition in CP may influence the gut microbiota. Fecal samples were obtained from 12 patients with AIP before the steroid therapy and 8 patients with CP. Metagenome DNA was extracted, and microbiota was analyzed by next generation sequencing. Gut microbiota profiles were different between patients with AIP and those with CP; namely, the proportions of Bacteroides, Streptococcus and Clostridium species were higher in patients with CP. The reasons for the increased proportion of these bacterial species remain unknown, but may reflect malabsorption and/or decreased pancreatic enzymes, both of which are associated with CP. Incidentally, the identified Streptococcus species are oral cavity inhabitants and also known as pathogens for
endocarditis
. Despite the small sample size, this study has shown the differences in gut microbiota profiles between AIP and CP. Comprehensive analysis of the gut microbiota may be useful for the differential diagnosis of pancreatic diseases.
