Background Portal hypertensive gastropathy (PHG) is often underestimated in clinical diagnosis. Gastrointestinal bleeding in cirrhosis of PHG accounts for approximately 10% of upper gastrointestinal bleeding. However, the relationship between PHG and gender, laboratory parameters, liver function and varices is still controversial. In the present study, we aimed to retrospectively evaluate the incidence of PHG and to explore the relationship between PHG and gender, laboratory parameters, liver function and varicose veins. Methods A retrospective analysis of 325 patients with cirrhosis who underwent esophagogastroduodenoscopy (EGD) in the Department of Gastroenterology of the Second Hospital of Hebei Medical University from 1 January 2018 to 31 December 2020 was performed. The relationships among age, gender, laboratory parameters, Child–Pugh stage, oesophageal varices (EV), gastric varices (GV) and ascites with PHG were analysed with univariate and multivariate logistic regression. Results The occurrence of PHG was significantly associated with gender, haemoglobin, platelet count, prothrombin time, albumin, Child–Pugh stage, EV, GV and ascites (P < 0.05). Furthermore, there was a positive correlation between the severity of PHG and the degree of EV, GV and ascites (P < 0.05). Multivariate logistic regression showed that albumin, EV and GV levels were independently associated with the occurrence of PHG. Conclusion The incidence of PHG in cirrhosis was 87.4% in this study. The occurrence of PHG was related to gender, haemoglobin, platelet count, prothrombin time, albumin, Child–Pugh stage, EV, GV and ascites. Albumin, the degree of EV and GV are independent risk factors for the occurrence of PHG.

Pancreas divisum (PD) is a common pancreatic malformation caused by the failure of fusion between ventral and dorsal pancreatic ducts. There is a small branch of communication between the two systems in incomplete PD, and this variation has an incidence of 15%. A 43-year-old female patient presented to our department with recurrent abdominal pain. Magnetic resonance cholangiopancreatography (MRCP) showed that the ventral pancreatic duct was curved, with a local pouchlike dilatation. Endoscopic ultrasonography supported the diagnosis of incomplete PD and showed a thin branch of communication between ventral and dorsal pancreatic ducts. Endoscopic retrograde cholangiopancreatography (ERCP) and papillotomy of the minor papilla with double plastic stent implantation were performed. One pancreatic plastic stent was inserted across the minor and major papilla over the guide wire, creating a U-shape. The other wire-guided plastic stent was inserted through the minor papilla into the dorsal pancreatic duct. The pancreatic fluid drained smoothly after stent placement. During the 6-month follow-up, the patient remained well, without recurrence of pancreatitis.

We examine the effect of directors' and officers' insurance (D&O insurance) on corporate idiosyncratic risk in the Chinese market. We find that D&O insurance in China is negatively associated with corporate idiosyncratic risk. This association is robust to a series of robustness checks, including propensity score matching procedure and the inclusion of some possibly omitted variables. Further analyses show that only the idiosyncratic risk of the state-owned enterprises (SOE) can be significantly affected by the purchase of D&O insurance. Moreover, we find that the impact of D&O insurance on idiosyncratic risk is more pronounced in firms with Big 4 auditors, higher analyst coverage, and higher growth rate. Our findings support the notion that D&O insurance appears to improve corporate governance and provide a new understanding of the effectiveness of D&O insurance in emerging economies.
