Diagnostic DBE is safe with a low complication rate. The complication rate of therapeutic DBE is high compared with therapeutic colonoscopy. The reason for this is unclear. The incidence of pancreatitis after DBE is low (0.3 %), but has to be considered in patients with persistent abdominal complaints after a DBE procedure.

The complete enteroscopy rate was three times higher with DBE than with SBE, accompanied by a higher diagnostic yield. DBE must therefore continue to be regarded as the nonsurgical gold standard procedure for deep small-bowel endoscopy.

In almost two-thirds of the patients examined, DBE was clinically useful for obtaining a new diagnosis and starting new treatments, changing existing treatments, carrying out surgical intervention, or providing therapeutic endoscopy. DBE is a useful and safe method of obtaining tissue for diagnosis, providing hemostasis, and carrying out polypectomy.

The pattern of bleeding following ES may not predict the risk of late bleeding. Abnormal labs are associated with visible bleeding. Epinephrine injection is safe and appears to provide effective hemostasis.

These findings suggest that oesophageal biopsies are useful to differentiate NERD from FH. Increased DIS and a histological sum score are the most significant histopathological abnormalities in NERD as compared with FH.

Background: Endoscopic retrograde cholangiopancreatography (ERCP) is technically challenging or impossible in patients with complex postsurgical anatomy. The aim of this cohort study was to assess the technical success of ERCP with the single balloon enteroscope (SBE) in patients with Roux-en-Y anastomosis. Patients: Patients with Roux-en-Y anastomosis presenting with cholestasis undergoing ERCP with the SBE technique in a tertiary university hospital. Diagnostic success was defined as successful duct cannulation or securing the diagnosis and therapeutic success was defined as the ability to successfully accomplish endoscopic therapy. Results: ERCP using the SBE was performed on 17 occasions in 13 patients (5 F, 8 M, mean age 66.5 years, range 25–77) with Roux-en-Y anastomosis. Indications for ERCP were biliary obstruction with common bile duct stones and/or cholangitis in all patients. The diagnostic success was 61.5% and the therapeutic success was 53.8%. Therapeutic interventions included dilation of common bile duct stenosis with a balloon (n = 4), biliary stent insertion (n = 2), removal of bile duct stones (n = 2), stent retrieval (n = 2), papillectomy (n = 1), and sphincterotomy (n = 1). No major complications occurred. Conclusions: ERCP using the SBE is feasible in patients with altered postsurgical anatomy presenting with biliary problems permitting diagnostic and therapeutic interventions.
