To investigate the irrigation and drainage strategy in severe acute pancreatitis after laparoscopic surgery.

The clinical data of 54 patients with non-biliary SAP and underwent the laparoscopic surgery from Jan. 2007 to Dec. 2015 were retrospectively analyzed. Using laparoscopic surgery, laparoscopic colon separated ligament stomach, pancreas into the omentum cavity exposed, the net absorption of exudate, peritoneal washing, remove pancreatic necrosis, in the lesser sac, pancreatic and pelvic placement lavage a plurality of drainage pipe and tube, after surgery using a variety of methods for subsequent irrigation and drainage.

50 cases was cured, 4 cases were died, in which 1 case died with pancreatic cancer, 2 cases died with delayed abdominal bleeding, 1 case died with multiple organ failure. The time of flushing was(21.6 ± 14.5)d, and the time of drainage tube extraction was(35.4 ± 22.4)d. The hospitalization time was(38.7 ± 24.6)d. 1 case was underwent the second laparoscopic surgery in 32 d after the first operation because of pancreatic abscess, 3 cases became to pancreatic pseudocyst. 1 case was cured with conservative treatment. 2 cases were cured after puncture and drainage.

Reasonable irrigation and drainage strategy after laparoscopic surgery can reduce mortality and reduce complications in SAP.
