The effect of endoscopic sphincterotomy in patients with acalculous biliary type pain and impaired caerulein-induced gallbladder ejection fraction – preliminary results

Introduction: Impaired gallbladder (GB) ejection fraction (GBEF) in patients (pts) with acalculous biliary type pain (ABP) is a commonly accepted phenomenon and most of these pts usually undergo cholecystectomy. The aim of our study is to evaluate the effect of endoscopic sphincterotomy (EST) in pts with ABP and impaired caerulein-induced GBEF. Patients and methods: 17 consecutive patients with right upper quadrant abdominal pain and without any organic disease/normal laboratory tests, upper gastrointestinal endoscopy and abdominal ultrasonography (US)/were enrolled until the end of February 2006. After an overn…
