Choledochoscopy combined with double-cannula lavage in the treatment of acute pancreatitis with encapsulated necrosis and the analysis of related inflammatory indexes

This study aimed to evaluate the application of choledochoscopy combined with double-cannula lavage in the treatment of acute pancreatitis (AP) with encapsulated necrosis and analyzed related inflammatory indexes.

Thirty patients with AP with encapsulated necrosis were enrolled and treated with choledochoscopy and double-cannula lavage. Serum white blood cell (WBC), procalcitonin (PCT), C-reactive protein (CRP), interleukin 6 (IL-6), IL-8, tumor necrosis factor alpha (TNF-α), and related inflammatory indexes were detected before and after surgery.

All of the participants who underwent the surgery recovered well and were discharged without serious complications; no deaths occurred. The serum WBC, PCT, and CRP of patients after surgery decreased compared with before the procedure, and the differences in WBC and CRP were statistically significant (P < 0.05); the difference in PCT was not statistically significant (P > 0.05). Postoperatively, IL-6, IL-8, and TNF-α levels were higher than before surgery, and the differences were statistically significant (P < 0.05).

The surgical method presented herein effectively controlled and alleviated the infection of patients; it also did not increase the risk of infection and can thus be considered a safe and effective surgical method.
