Surgical Treatment of Pancreatico-enteric Anastomosis Stenosis and Post-operative Chronic Pancreatitis
Pancreaticojejunostomy stricture (PJS), which has been less studied and no treatment consensus till now, is a late complication after pancreaticoduodenectomy (PD). However, the incidence is increasing since the postoperative survival time after PD was prolonged. The incidence of PJS reached about 2–5% [1–3], which was very low, only one paper reported the incidence rate of 11.3% (27/237) . PJS mainly occurs in patients with benign diseases such as IPMN and chronic pancreatitis underwent PD, but the high risk factors were not apparent. Coiffi et al.  reported the diagnosis and treatment of 26 patients with PJS, of which 19% are chronic pancreatitis, 32% are IPMN, and 26% are ampullary malignant tumors with PD. There was little analysis of PJS in pancreatic cancer and other malignant tumors, there is only one study described the incidence of PJS after PD in 310 malignant tumors, which is 1.93% .
