OBJECTIVES: Chronic pancreatitis produces disabling pain and loss of pancreatic endocrine/exocrine function. Almost half of the patients will need surgery during the course of the disease. Certain conditions, such as extrahepatic portal hypertension or cavernous transformation of the portal vein, can increase the risk of morbidity and mortality. These complications must be borne in mind in the design of the surgical treatment of chronic pancreatitis. This study is a systematic review on the coexistence of chronic pancreatitis and extrahepatic portal hypertension/cavernous transformation in patients undergoing pancreatic surgery. METHODS: We conducted an unlimited search updated on 10 December 2017, which yielded 535 results. We selected 11 articles. RESULTS: Main indication for surgery was intractable pain. Presence of extrahepatic portal hypertension and/or cavernous transformation increased intraoperative bleeding and general postoperative morbidity, though the increase in general morbidity was less when the different postoperative complications were analyzed individually. Case series showed a higher mortality in patients with extrahepatic portal hypertension. CONCLUSION: Little is known about the presence of extrahepatic portal hypertension in patients undergoing pancreatic surgery for chronic pancreatitis. More studies are needed in order to standardize criteria for vascular involvement in patients with chronic pancreatitis, in order to select the surgical technique and, if necessary, to establish contraindications, in this subgroup of patients.
