Preventive and therapeutic significance of octreotide combined with lansoprazole on post-ERCP pancreatitis and its effect on serum amylase, inflammatory factors and immune function.

The study aimed to investigate the preventive and therapeutic significance of octreotide combined with lansoprazole on post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) and its effects on serum amylase (AMS), inflammatory factors and immune function. A total of 132 patients who underwent ERCP in Shaoxing People's Hospital (Shaoxing, China) were enrolled in the study and allocated into two groups: The study group (octreotide plus lansoprazole, 68 cases) and the control group (octreotide alone, 64 cases). The incidence of PEP and post-ERCP hyperamylasemia (PEH), the concentrations of serum AMS, interleukin-17 (IL-17) and tumor necrosis factor-α (TNF-α), as well as the T-lymphocyte population in peripheral blood were detected. The AMS levels in the study group were significantly lower than those in the control group at 6 and 24 h after treatment (P<0.001). The incidence of PEP and PEH, symptom disappearance time and hospital stay in the study group were significantly lower than those in the control group after treatment (P<0.05). The levels of IL-17 and TNF-α in the study group were significantly lower than those in the control group after treatment (all P<0.05). The percentage of CD3, CD4, CD8 cells and the ratio of CD4/CD8 in the study group were significantly higher than those in the control group after treatment (all P<0.05). The results indicated that octreotide combined with lansoprazole reduces AMS levels and the incidence of PEP, alleviates inflammation and improves the immune function.
