Kager LM, et al. – This systematic review intended to define patient characteristics and imaging features of groove pancreatitis (GP) and to evaluate clinical outcomes after treatment. GP was correlated with male gender, smoking, and alcohol consumption and the vast majority of patients presented with abdominal pain and with cystic lesions on imaging. Both conservative and endoscopic treatment were successful in about half of patients although surgical treatment seemed to be the most effective. A stepwise treatment algorithm starting with the least invasive treatment options appeared advisable.
