Acute esophageal necrosis as a complication of diabetic ketoacidosis: A case report.

Background: Acute esophageal necrosis (AEN) is a rare condition that has been associated with low volume states, microvascular disease, gastrointestinal (GI) mucosal damage, and impaired GI motility. It has been linked in case reports with diabetic ketoacidosis (DKA) and is commonly associated with GI bleeding (GIB).

Case Summary: We report a case of endoscopy confirmed AEN as a complication of DKA in a 63-year-old Caucasian male without any overt GIB and a chief complaint of epigastric pain.

The Benefit of Fentanyl in Effective Sedation and Quality of Upper Endoscopy: A Double-Blinded Randomized Trial of Fentanyl Added to Midazolam Versus Midazolam Alone for Sedation.

Aims: Our goals were to compare the effect of adding fentanyl to midazolam in a double-blinded, randomized, placebo-controlled trial and determine if fentanyl enhances sedation, increases adverse events or effects time of the procedure or discharge.

Methods: Patients 18 to 65 years scheduled for outpatient upper endoscopy were eligible for the study. Patients were randomized to receive either 100 mcg/2 mL of Fentanyl or 2 mL of placebo IV with a double-blinded protocol.

Optimal electrical stimulation modality for cortical esophageal evoked potentials: transmural or intraesophageal?

Esophageal electrical stimulation using short and a relatively small number of (200 micros, 0.2 Hz, n = 25) electrical pulses generates a characteristic and well defined cortical evoked potential response (EP). There are two methods of stimulation: either through intraesophageal electrodes or with transmural electrodes.
