Continuous regional arterial infusion and laparotomic decompression for severe acute pancreatitis with abdominal compartment syndrome

AIM：To evaluate the therapeutic effects of abdominal decompression plus continuous regional arterial infusion（CRAI） via a drug delivery system（DDS） in severe acute pancreatitis（SAP） patients with abdominal compartment syndrome（ACS）.METHODS：We presented our recent experience in 8 patients with SAP.The patients developed clinical ACS,which required abdominal decompression.During the operation,a DDS was inserted into the peripancreatic artery（the catheter was inserted from the right gastroepiploic artery until it reached the junction between the pancreaticoduodenal and gastroduodenal artery）.Through this DDS,a protease inhibitor,antibiotics and octreotide were infused continuously.The duration of the regional artery infusion ranged from 8 to 41 d.The outcomes and the changes in the APACHE Ⅱ score,computed tomography（CT） severity index and intraabdominal pressure（IAP） of the patients were retrospectively evaluated.RESULTS：Eight patients with an initial APACHE Ⅱ score of 18.9（range,13-27） and a Balthazar CT severity index of 9.1（range,7-10） developed severe local and systemic complications.These patients underwent subsequent surgical decompression and CRAI therapy because of intra-abdominal hypertension（IAH）.After a mean interval of 131.9 ± 72.3 d hospitalization,7 patients recovered with decreased APACHE Ⅱ scores,CT severity indexes and IAP.The mean APACHE Ⅱ score was 5.4（range,4-8）,the CT severity index was 2.3（range,1-3）,and IAP decreased to 7.7 mmHg（range,6-11 mmHg） 60 d after operation.One patient died of multiple organ failure 1 wk after surgery.CONCLUSION：CRAI and laparotomic decompression might be a therapeutic option for SAP patients with ACS.
