RESUMO
Background: Endoscopic retrograde cholangiopancreatography (ERCP) is used to diagnose and treat pancreatic and biliary disease. The current standard is to conduct ERCP under conscious sedation (CS). Patient movement and agitation during ERCP under CS can result in procedure failure and complications. Aiming to reduce procedure failure rates and complications, Kelowna General Hospital (KGH) in British Columbia, Canada transitioned to performing ERCP under general anesthesia (GA) as the practice standard. Objective: To determine if conducting ERCP under GA compared to CS decreases procedure complications, particularly post-ERCP pancreatitis (PEP). Methods: The charts of 2,198 patients who underwent ERCP at KGH between 2015 and 2020 were reviewed. Before September 17, 2017, ERCP was performed under CS (n = 1,316). Afterwards, ERCP was conducted under GA (n = 882). Demographic, clinical, and procedural data were extracted. The data were analyzed using univariate and multivariate statistical analysis. Results: Procedure failure rates (CS = 9 percent, GA = 3 percent, P < 0.001) decreased in the GA cohort after adjusting for age, sex, and co-morbidities. Thirty-day mortality, intensive care unit (ICU) transfer, returns post-discharge, PEP, and cholangitis rates were similar between cohorts. Conclusion: Performing ERCP under GA compared to CS resulted in an increase in procedural success rates. Other complication rates were similar between groups.
RESUMO
The main objective of this study was to determine whether acute ingestion of a ketone monoester (KME) supplement impacted mixed-meal tolerance test (MMTT) glucose area under the curve (AUC). Nineteen healthy young volunteers (10 males/9 females; age, 24.7 ± 4.9 years; body mass index, 22.7 ± 2.4 kg/m2) participated in a double-blind, placebo-controlled crossover study. Following overnight fasting (≥10 h), participants consumed 0.45 mL/kg of a KME supplement or taste-matched placebo followed by an MMTT 15 min later. Blood samples were collected every 15-30 min over 2.5 h. KME supplementation acutely raised ß-hydroxybutyrate AUC (590%, P < 0.0001, d = 2.4) and resulted in decreases in blood glucose AUC (-9.4%, P = 0.03, d = 0.56) and nonesterified fatty acid (NEFA) AUC (-27.3%, P = 0.023, d = 0.68) compared with placebo. No differences were found for plasma insulin AUC (P = 0.70) or gastric emptying estimated by co-ingested acetaminophen AUC (P = 0.96) between ketone and placebo. Overall, results indicate that KME supplementation attenuates postprandial glycemic and NEFA responses when taken 15 min prior to a mixed meal in young healthy individuals. Future studies are warranted to investigate whether KME supplementation may benefit individuals with impaired glycemic control. Novelty: Acute ketone monoester supplementation 15 min prior to a mixed meal decreased postprandial glucose and NEFA levels without significantly impacting postprandial insulin or estimates of gastric emptying. Glucose- and NEFA-lowering effects of ketone monoester supplementation are apparently not mediated by changes in insulin release or gastric emptying.
