Clinical experience of surgical intervention for severe acute pancreatitis

The controversy on the treatment strategy for severe acute pancreatitis (SAP) has never stopped for the past century. Even now surgical procedures play a decisive role in the treatment of SAP, especially in managing the related complications, but the rational indications, timing, and approaches of surgical intervention for SAP are still inconclusive.

Clinical data of 308 SAP patients recruited during January 2000-January 2013, including 96 conservatively treated cases plus 212 surgically intervened cases, were comparatively analyzed. Based on the initial surgical intervention time, the surgical intervention group was split into two: early intervention group (within 2 weeks) 103 cases, and late intervention group (after 2 weeks) 109 cases.

In the conservative treatment group, the cure rate was 82.29% (79/96), the death rate was 13.54% (13/96), and 4 cases self-discharged, while in the surgical intervention group, the cure rate was 84.43% (179/212) and the death rate was 10.85% (23/212) with 10 cases self-discharged. The difference was of no statistical significance between these two groups (P > 0.05). In surgical intervention group, the death rate 15.53% (16/103) in the early surgical intervention group was higher than that of late surgical intervention group 6.42% (7/109), and the difference was statistically significant (P < 0.05).

Both conservative treatment and surgical intervention play important roles in the treatment of SAP, and the indication, timing, and procedure should be strictly followed. Surgery earlier than 2 weeks after onset of the disease is not recommended in patients with necrotizing pancreatitis only when there are specific indications, such as multiple organ failure, which does not improve despite active treatment, and in those who develop abdominal compartment syndrome.
