BACKGROUND/AIMS: Endoscopic pancreatic stenting (EPS) has been used to treat main pancreatic duct (MPD) stricture in chronic pancreatitis (CP), with favourable reported results. However, most studies were retrospective and uncontrolled. We conducted a longterm prospective controlled study of EPS for treatment of MPD stricture in CP.
METHODOLOGY: Consecutive patients with CP were treated to remove pancreatic stones by extracorporeal shock-wave lithotripsy or endoscopic basket extraction. After treatment, 41 patients were enrolled in the study upon meeting the criteria of complete removal of stones, pain relief after the treatment, and dominant stricture of the MPD. Twenty patients chose EPS, while 22 control patients did not. We compared recurrence of pain and pancreatic function between groups for over 3 years of follow-up.
RESULTS: The mean follow-up period was 62.5 ± 20.9 months. Pain recurred in 15% of EPS patients (3/20) and in 50.0% of control patients (11/22), a significant difference (p<0.05). Progression of exocrine insufficiency in the EPS group was significantly slower than in the control group (p<0.05), while endocrine function showed no difference between groups.
CONCLUSIONS: EPS reduced pain recurrence and slowed down the progression of exocrine insufficiency in CP patients with MPD stricture.
