Chemerin: a new biomarker to predict postendoscopic retrograde cholangiopancreatography pancreatitis

Risk factors for post‑retrograde cholangiopancreatography pancreatitis in patients with common bile duct stones: A meta‑analysis

Endoscopic retrograde cholangiopancreatography (ERCP) has become a common treatment method for common bile duct stones. However, ERCP is also associated with a high risk of post-endoscopic retrograde cholangiopancreatography pancreatitis (PEP). Identification of risk factors is essential for reducing the incidence of PEP. The present study aimed to summarize the risk factors for PEP by performing a meta-analysis. Therefore, studies published between 2000 and 2022 were screened in PubMed, Cochrane Library, Embase, Web of Science, China National Knowledge Infrastructure, Wanfang Digital Periodicals and the Weipu Database, with no language restrictions. Newcastle-Ottawa Scale was used to assess the quality of the included studies. Stata 17.0 software was utilized for the meta-analysis of 14 possible risk factors. Overall, 15 high-quality studies were included into the present meta-analysis. The results showed that female [odds ratio (OR), 1.42; 95% CI, 1.23-1.64), age <60 years (OR, 1.53; 95% CI, 1.06-2.21), difficult intubation (OR, 4.87; 95% CI, 2.73-8.68), ≥3 cannulation attempts (OR, 9.64; 95% CI, 4.16-22.35), cannulation time ≥10 min (OR, 2.37; 95% CI, 1.67-3.35), history of pancreatitis (OR, 2.95; 95% CI, 1.06-5.51), pancreatic duct visualization (OR, 3.63; 95% CI, 2.47-5.34) and sphincter of Oddi dysfunction (OR, 5.72; 95% CI, 1.80-18.24) are potential risk factors for PEP (P<0.05). In conclusion, the present meta-analysis suggests that PEP can be affected by several risk factors, particularly the technique-related factors such as the frequency and time of cannulation. Therefore, effective precautions should be taken as early as possible to reduce the incidence of PEP.

Clinical treatment for persistent inflammation, immunosuppression and catabolism syndrome in patients with severe acute pancreatitis (Review)

Severe acute pancreatitis (SAP) is a severe disease with a high prevalence and a 3-15% mortality worldwide, and premature activation of zymogen for any reason is the initial factor for the onset of SAP. Gallstone disease and heavy alcohol consumption are the two most common etiologies of SAP. Persistent inflammation, immunosuppression and catabolism syndrome (PICS) is a life-threatening illness, and there are no effective treatments. The relapse state of PICS mainly leads to high mortality due to septic shock or severe trauma, both of which are dangerous and challenging conditions for clinicians. Thus, it is important for medical staff to identify patients at high risk of PICS and to master the prevention and treatment of PICS in patients with SAP. The present review aims to increase the understanding of the pathogenesis of PICS, produce evidence for PICS diagnosis and highlight clinical treatment for PICS in patients with SAP. With this information, clinical workers could implement standardized and integrated measures at an early stage of SAP to stop its progression to PICS.
