RESUMEN
BACKGROUND: Severe acute pancreatitis (SAP), one severe and fatal disease, the therapy of which is pretty hard. This study aimed to study the effect of laparoscopic peritoneal lavage and drainage (LPLD) and continuous venovenous diahemofiltration (CVVDH) on SAP. MATERIALS AND METHODS: Two hundred forty-five patients with SAP in total were randomly assigned into four groups according to the therapeutic plan: basic treatment; LPLD; CVVDH; or LPLD+CVVDH. Acute Physiology and Chronic Health Evaluation II (APACHE II) scores, the ratios of multiple organ dysfunction syndrome (MODS), mortality, hospitalization time, hospitalization cost, ratios of complications, the abdominal distention relief time, abdominal pain relief time, plasma concentration of endotoxin, tumor necrosis factor-α (TNF-α), interleukin (IL)-6, and IL-8 were evaluated. RESULTS: Ratios of MODS, mortality, hospitalization time, hospitalization cost, the abdominal distention relief time, abdominal pain relief time, concentration of endotoxin, TNF-α, IL-6, IL-8, and APACHE II scores were significantly decreased in the CVVDH, LPLD, and CVVDH+LPLD groups, while ratios of recovery were significantly increased in the CVVDH, LPLD, and CVVDH+LPLD groups, especially in the CVVDH+LPLD group. CONCLUSIONS: LPLD and CVVDH are effective in the treatment of SAP by eliminating endotoxin, TNF-α, IL-6, and IL-8. The combination of CVVDH and LPLD can further improve the treatment effect.
