Natural orifice translumenal endoscopic drainage for pancreatic abscesses

Background  Few series describe endoscopic drainage of pancreatic abscesses. Abscesses are complications of pancreatitis, presenting with sepsis, peritonitis, or both. This report describes the feasibility and efficacy of natural orifice translumenal endoscopic surgery for pancreatic abscesses. Methods  This study reviewed 35 consecutively treated patients for the period 1994–2007. The approaches alone or in combination were transmural (transgastric or transduodenal) and transpapillary. The criteria for abscesses were two or more of the following: fever, abdominal pain, elevated white blood count (WBC), and positive fluid cultures. Results  The 35 patients (19 men and 16 women) had a mean age of 49 years. The abscesses had idiopathic (37%), gallstone (32%), alcohol (20%), and divisum (11%) etiologies. The presenting signs were abdominal pain (80%), positive cultures (69%), fever (57%), elevated WBC (51%), and nausea/vomiting (39%). The approaches for abscess drainage were as follows: transgastric (n = 15, 43%), transduodenal (n = 4, 11%), transgastric combined with transpapillary (n = 8, 23%), transduodenal combined with transpapillary (n = 1, 3%), and transpapillary alone (n = 7, 20%). A total of 28 patients (80%) achieved successful endoscopic pancreatic abscess drainage, whereas 7 (20%) required surgery. Of these seven patients, two (6%) required emergent laparotomy to control bleeding, and the remaining five (14%) were explored after failure to demonstrate clinical improvement from endoscopic drainage. Three patients required internal drainage, and two patients required distal pancreatectomy. The mean follow-up period was 15 months, and the complication rate was 6%. No one died from the procedure. Conclusion  Endoscopic surgery for pancreatic abscess is feasible and effective. It is an alternative to surgery that currently can be considered a primary treatment option for selected pancreatic abscesses.
