Factors affecting pancreatic hyperamylasemia in patients undergoing peroral single-balloon enteroscopy.
Digestive Endoscopy : Official Journal of the Japan Gastroenterological Endoscopy Society 2015 September
BACKGROUND AND AIM: Acute pancreatitis following balloon-assisted enteroscopy is a rare but serious complication. The causative mechanism is uncertain and prevention strategies are not established. We conducted a retrospective study to clarify the risk factors for pancreatic hyperamylasemia.
METHODS: Eighty-four patients undergoing peroral single-balloon enteroscopy (SBE) were enrolled in this study. Serum pancreatic and salivary amylase levels were measured 2 h after endoscopic examination.
RESULTS: We experienced three patients with post-SBE pancreatitis. Factors predicting pancreatic hyperamylasemia were: (i) elderly patients; (ii) deeper insertion; and (iii) clockwise insertion. In contrast, younger age at examination was a significant factor observed in salivary hyperamylasemia.
CONCLUSIONS: It is important to measure pancreatic amylase and not total amylase after SBE. When carrying out peroral SBE, the distance of insertion should be reduced especially if the scope traces a clockwise loop or the subject is elderly.
