BACKGROUND AND STUDY AIMS: Endoscopic ductal decompression therapy has become an established method of treating patients with painful obstructive chronic pancreatitis. Smaller series, mostly with a medium-term follow-up period, have reported encouraging results. The present analysis presents long-term follow-up data from a large multicenter patient cohort. PATIENTS AND METHODS: Patients with painful chronic pancreatitis and with ductal obstruction due to either strictures and/or stones treated endoscopically at eight different centers underwent follow-up after 2 - 12 years (mean 4.9 years). The patients' clinical data, the rate of technical success, and complications were recorded from the charts. Follow-up data were prospectively obtained using structured questionnaires; the main parameter for evaluating treatment success was a significant reduction in pain (no pain or only weak pain). RESULTS: Follow-up data were obtained from 1018 of 1211 patients treated (84%) with mainly strictures (47%), stones (18%), or strictures plus stones (32%). At the long-term follow-up, 60% of the patients had their endotherapy completed, 16% were still receiving some form of endoscopic treatment, and 24% had undergone surgery. The long-term success of endotherapy was 86% in the entire group, but only 65% in an intention-to-treat analysis. There were no significant differences between the patient groups with regard to either strictures, stones, or both. Pancreatic function was not positively affected by endoscopic therapy. CONCLUSIONS: Endoscopic ductal decompression therapy offers relief of pain in two-thirds of the patients when it is used as the only form of treatment. One-quarter of the patients have to undergo surgery.
