Résumé : BACKGROUND: EUS-guided pancreatogastrostomy (EPG) is described as an alternative to surgery for ductal decompression in symptomatic patients when endoscopic transpapillary access of the main pancreatic duct (MPD) is impossible. OBJECTIVE: To present the midterm clinical response and follow-up of a larger group of patients treated with EPG and a new transbulbar approach, EUS-guided pancreatobulbostomy (EPB). DESIGN: Retrospective case review. SETTING: Two tertiary referral centers in Brussels and Marseille. PATIENTS: From 2000 to 2004, 36 patients (51 years old; range, 14-71 years) were seen. INTERVENTION: EPG or EPB. MAIN OUTCOME MEASUREMENTS: Pain relief, technical aspects, complications, and clinical follow-up. RESULTS: Indications were chronic pancreatitis, with complete obstruction (secondary to a tight stenosis, a stone, or MPD rupture); inaccessible papilla or impossible cannulation (n = 20); anastomotic stenosis after a Whipple procedure (n = 12); complete MPD rupture after acute pancreatitis (AP); or trauma (n = 4). EPG or EPB was unsuccessful in 3 patients; 1 was lost to follow-up. Major complications occurred in 2 patients and included 1 hematoma and 1 severe AP. The median follow-up was 14.5 months (range, 4-55 months). Pain relief was complete or partial in 25 patients (69%, intention to treat). Eight patients treated had no improvement of their symptoms (4 were subsequently diagnosed with cancer). Stent dysfunction occurred in 20 patients (55%) and required a total of 29 repeat endoscopies. LIMITATIONS: Technically demanding and requires careful pretherapeutic evaluation. CONCLUSIONS: EPG or EPB appears to be an effective and relatively safe treatment for the management of pain secondary to pancreatic ductal hypertension in patients with an MPD not accessible by a transpapillary route.
