Endoscopic sphincterotomy for acute relapsing pancreatitis associated with periampullary diverticula: a long-term follow-up.

BACKGROUND AND STUDY AIMS: Periampullary diverticula (PAD) are extraluminal outpouchings of the duodenum arising within a radius of 2-3 cm from the ampulla of Vater. Data concerning the association of PAD with biliopancreatic disease are inconsistent, but an association between acute pancreatitis and PAD has been reported. The aim of this retrospective study was to evaluate the outcome of endoscopic sphincterotomy (ES) in a Greek cohort of patients with acute relapsing pancreatitis associated with PAD.

PATIENTS AND

METHODS

A total of 344 patients who had undergone ERCP between 1994 and 2005 for investigation of acute pancreatitis were retrospectively entered into a database. Of these patients, 11 (3.19% ; median age: 69 years; range: 58-78; 3 men, 8 women) were found to have acute relapsing pancreatitis associated with PAD. All patients underwent ES and were followed for new episodes of acute pancreatitis or other complications.

RESULTS

No further episodes of acute pancreatitis occurred after ES, during a long-term follow-up (median: 4.3 years, range: 1.9-10.4). Two patients (18.2%) presented post-procedure mild pancreatitis and one patient (9.1%) post-ES stenosis with two small common bile duct stones and was treated with ES and extraction of stones.

CONCLUSION

ES is the treatment of choice for patients with acute relapsing pancreatitis associated with PAD.
