Abstract

BACKGROUND:

Much attention has been focused on the competence to perform endoscopic procedures. The aim of this study was to determine the impact of procedure experience on patient outcomes after endoscopic pancreatic fluid collection drainage.

METHODS:

Outcomes for consecutive patients with symptoms from pancreatic fluid collections who were referred for endoscopic transmural and/or transpapillary drainage were analyzed retrospectively. Collections were classified as acute pseudocyst, chronic pseudocyst, and pancreatic necrosis. To assess the impact of endoscopist experience, outcomes for patients who underwent the first 20 procedures were compared with those for patients who had subsequent procedures.

RESULTS:

In total, 175 patients underwent pancreatic fluid collection drainage; 40 (23%) acute pseudocyst, 78 (44%) chronic pseudocyst, and 57 (33%) pancreatic necrosis. Procedure complication rates, collection recurrence rates, and patient outcomes after acute pseudocyst drainage were independent of endoscopist experience. There was a dramatic improvement in chronic pseudocyst resolution rates after the first 20 procedures versus subsequent procedures (45% vs. 93%; p = 0.0002) and a reduction in days to resolution (50 days, initial 20 procedures vs. 33.5 days, subsequent procedures; p = 0.05). In patients with pancreatic necrosis, there was a decrease in median hospital stay with greater experience (23 days to 15 days; p = 0.04).

CONCLUSIONS:

Resolution of chronic pseudocyst after endoscopic drainage improves markedly with increasing endoscopist experience. Future prospective studies assessing skill acquisition are required to define the minimum number of collection drainage procedures at which competence can be achieved.
