Objectives: Regulatory changes requiring the use of capnographic monitoring for endoscopic procedures using moderate sedation have placed financial challenges on ambulatory and hospital endoscopy centers across the United States due to the increased cost of training endoscopy personnel and purchasing both capnography-monitoring devices and specialized sampling ports. To date, there has been no published data supporting the use of capnographic monitoring in adult patients undergoing routine endoscopic procedures with moderate sedation. The aim of this randomized, parallel group assignment trial was to determine whether intervention based on capnographic monitoring improves detection of hypoxemia in patients undergoing routine esophagogastroduodenoscopy (EGD) or colonoscopy with moderate sedation.

This case illustrates a rare cause of gastro-intestinal bleeding following bariatric surgery. Though it is essential to rule out common causes of variceal formation accompanied by intermittent, profuse bleeding, there should be a high degree of suspicion of this rare etiology in patients who have previously undergone alteration of their anatomy, especially Roux-en-Y gastric bypass (RYGB). The case emphasizes the need for a multidisciplinary medical-surgical team in evaluating and treating patients who present with complex intra-abdominal pathology.

Background & Aims: Ventricular assist devices (VADs) are used to treat patients with end-stage heart disease. However, patients with VADs frequently develop gastrointestinal (GI) bleeding. We investigated the incidence, etiology, and outcome of GI bleeding in patients with VADs.

Objective: The aims of this study were to determine the effects of length of procedure on endoscopic retrograde cholangiopancreatography (ERCP) outcomes and adverse events.

Methods: All ERCP procedures, performed by experienced advanced endoscopists, in patients without prior papillary intervention from 2006 to 2008 were reviewed. Procedures were arbitrarily divided into two groups: shorter procedures (SP), with a duration shorter than the overall mean procedure length, and longer procedures (LP), with a duration longer than overall mean procedure length.

Background: Obstructive sleep apnea (OSA), which is linked to the prevalence of obesity, continues to rise in the United States. There are limited data on the risk for sedation-related adverse events (SRAE) in patients with undiagnosed OSA receiving propofol for routine EGD and colonoscopy.

Objective: To identify the prevalence of OSA by using the STOP-BANG questionnaire (SB) and subsequent risk factors for airway interventions (AI) and SRAE in patients undergoing elective EGD and colonoscopy.

Background: Physician fatigue and decreased concentration have been proposed as causes of lower completion and adenoma detection rates in afternoon colonoscopies compared with morning colonoscopies. ERCP is a technically demanding and highly operator-dependent procedure, and its success may similarly be affected in the afternoon compared with the morning.

Objective: To compare cannulation success and adverse events between ERCP procedures performed in the morning and afternoon.

Objectives: While some gastroenterologists provide their own sedation for endoscopic retrograde cholangiopancreatography (ERCP), others utilize anesthesiologists. There is limited information comparing cannulation success and complication rates between these two approaches. Theoretically, anesthesiologist-directed sedation (ADS) may lead to an improved deep cannulation rate by virtue of using deeper and more constant levels of sedation and by removing the minute-by-minute medication management and physiologic monitoring responsibilities from the endoscopy team.
