RESUMO
BACKGROUND & AIMS: The Cotton Consensus (CC) criteria for post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) may not capture post-ERCP morbidity. PAN-PROMISE, a patient-reported outcome measure (PROM), was developed to quantify acute pancreatitis-related morbidity. This study aims to determine the value of PAN-PROMISE in independently defining ERCP-related morbidity. METHODS: We conducted a prospective cohort study of patients undergoing ERCP at 2 academic centers from September 2021 to August 2022. We administered PAN-PROMISE and assessed quality of life and work productivity at baseline, 48 to 72 hours, 7 days, and 30 days following ERCP. PEP was defined by a 3-physician committee using the CC criteria. We defined high morbidity following ERCP (elevated PROM) by an increase of PAN-PROMISE score of >7 at 7 days post-procedure. The McNemar test assessed discordance between PEP and elevated-PROM. RESULTS: A total of 679 patients were enrolled. Choledocholithiasis (30%) and malignant biliary obstruction (29%) were the main indications for ERCP. Thirty-two patients (4.7%) developed PEP. One hundred forty-seven patients (21.6%) had an elevated PROM, whereas only 20 of them (13.4%) had PEP by the CC criteria (P < .001 for discordance). An elevated PROM strongly correlated with lower physical quality of life and increased direct and indirect health care costs ($80 and $25 per point increase in PAN-PROMISE, respectively). Patients with pancreatic cancer (odds ratio, 4.52; 95% confidence interval, 1.68-10.74) and primary sclerosing cholangitis (odds ratio, 1.79; 95% confidence interval, 1.29-2.45) had the highest odds of elevated PROM. CONCLUSIONS: A substantial number of patients experience significant morbidity after ERCP despite not developing PEP or other adverse events. Future studies are needed to characterize better the reasons behind this increase in symptoms and potential interventions to reduce the symptom burden post-ERCP. CLINICALTRIALS: gov number, NCT05310409.

Afferent loop syndrome can result from both benign and malignant strictures of the biliary limbs of patients with surgically altered anatomy. Afflicted patients accumulate intestinal and pancreaticobiliary secretions, which leads to bowel distention and pain. We describe the endoscopic management of a 52-year-old woman with a history of Billroth II gastrojejunostomy due to gastric cancer who developed malignant gastric outlet obstruction and subsequently malignant afferent loop syndrome, using lumen-apposing metal stents.

RESUMO
Lucinidae clams harbor gammaproteobacterial thioautotrophic gill endosymbionts that are environmentally acquired. Thioautotrophic lucinid symbionts are related to metabolically similar symbionts associated with diverse marine host taxa and fall into three distinct phylogenetic clades. Most studies on the lucinid-bacteria chemosymbiosis have been done with seagrass-dwelling hosts, whose symbionts belong to the largest phylogenetic clade. In this study, we examined the taxonomy and functional repertoire of bacterial endosymbionts at an unprecedented resolution from Phacoides pectinatus retrieved from mangrove-lined coastal sediments, which are underrepresented in chemosymbiosis studies. The P. pectinatus thioautotrophic endosymbiont expressed metabolic gene variants for thioautotrophy, respiration, and nitrogen assimilation distinct from previously characterized lucinid thioautotrophic symbionts and other marine symbionts. At least two other bacterial species with different metabolisms were also consistently identified in the P. pectinatus gill microbiome, including a Kistimonas-like species and a Spirochaeta-like species. Bacterial transcripts involved in adhesion, growth, and virulence and mixotrophy were highly expressed, as were host-related hemoglobin and lysozyme transcripts indicative of sulfide/oxygen/CO2 transport and bactericidal activity. This study suggests the potential roles of P. pectinatus and its gill microbiome species in mangrove sediment biogeochemistry and offers insights into host and microbe metabolisms in the habitat.
