RESUMO

AIM: Echocardiography is necessary for portopulmonary hypertension diagnosis, and identifying patients with cirrhosis who require it is challenging. In this study, we aimed to investigate the utility of the total bile acid (TBA) levels as a screening tool for identifying patients with decompensated cirrhosis who should undergo echocardiography for portopulmonary hypertension diagnosis. METHODS: We evaluated 135 patients with decompensated cirrhosis who underwent liver transplantation. Subsequently, factors contributing to tricuspid regurgitation pressure gradient (TRPG) elevation (≥30 mmHg) were analyzed using preoperative data, including the TBA levels. RESULTS: The median age of patients was 58 years (61 women), and 45 and 90 patients had Child-Turcotte-Pugh grades of B and C, respectively. The median TRPG level was 21 mmHg, and 17 patients (12.6%) showed TRPG elevation. Multiple logistic regression analysis revealed that elevated TBA (odds ratio 4.322; p = 0.013) and main pulmonary artery diameter ≥33 mm (odds ratio 4.333; p = 0.016) were significantly associated with TRPG elevation. The TBA cut-off value (167.7 µmol/L) showed a high diagnostic performance, with 70.6% sensitivity and 64.4% specificity. Ursodeoxycholic acid (UDCA) administration increased the TBA levels dose-dependently. Analysis stratified by UDCA use revealed that in patients not taking UDCA (n = 59), elevated TBA levels and younger age significantly contributed to TRPG elevation. However, in those taking UDCA (n = 76), this contribution disappeared, suggesting that UDCA consumption reduced TBA levels' efficiency in diagnosing TRPG elevation. CONCLUSIONS: The TBA levels may be a potential screening tool for TRPG elevation; however, caution is warranted when interpreting cases treated with UDCA.

RESUMO

Gallbladder (GB) disease is classified into two broad categories: GB wall-thickening and protuberant lesions, which include various lesions, such as adenomyomatosis, cholecystitis, GB polyps, and GB carcinoma. This review summarizes recent advances in the differential diagnosis of GB lesions, focusing primarily on endoscopic ultrasound (EUS) and related technologies. Fundamental B-mode EUS and contrast-enhanced harmonic EUS (CH-EUS) have been reported to be useful for the diagnosis of GB diseases because they can evaluate the thickening of the GB wall and protuberant lesions in detail. We also outline the current status of EUS-guided fine-needle aspiration (EUS-FNA) for GB lesions, as there have been scattered reports on EUS-FNA in recent years. Furthermore, artificial intelligence (AI) technologies, ranging from machine learning to deep learning, have become popular in healthcare for disease diagnosis, drug discovery, drug development, and patient risk identification. In this review, we outline the current status of AI in the diagnosis of GB.

RESUMO

Background and Aim: Reports have indicated that a surface area of 4 mm2 or more of collected tissue sections could provide the recommended total DNA for the OncoGuide NCC Oncopanel system, which is a cancer gene panel test developed in Japan. We wished to compare the percentage of tissue sections collected by endoscopic ultrasound-assisted tissue acquisition (EUS-TA) with surface areas of ≥4 mm2 between a conventional needle, namely the EZ Shot 3 Plus (Olympus Medical Japan, Tokyo, Japan) (EZ3), and the recent SonoTip TopGain (MediGlobe, Rohrdorf, Germany) (TopGain). Method: From April 2010 to December 2021, among 693 EUS-TA cases, EZ3 was used in 390 cases and TopGain in 45. The EZ3 and TopGain groups were matched in a 1:1 ratio with a tolerance of 0.2, with 35 patients each matched using propensity score analysis. Results: The TopGain group had a significantly higher percentage of cases with a tissue area of ≥4 mm2 than the EZ3 group (42.9% vs 68.6%, P = 0.030). Multivariate analysis revealed an association between TopGain and tissue areas of ≥4 mm2 (odds ratio 2.996, 95% confidence interval 1.068-8.403, P = 0.037). Conclusions: EUS-TA using TopGain significantly collected more ≥4 mm2 tissue area compared with EZ3, suggesting its usefulness for cancer gene panel testing.

RESUMO

BACKGROUND AND AIM: This study aimed to compare patients with and without sedation during emergency endoscopy for upper gastrointestinal bleeding (UGIB) and to clarify the safety and efficacy of sedation in emergency endoscopy. METHODS: We retrospectively collected 389 patients who underwent emergency endoscopy for UGIB at Ureshino Medical Center from 2016 to 2021. Patients were divided into two groups: sedation group during emergency endoscopy and nonsedation group. Clinical characteristics, patient status on admission, and UGIB etiology were evaluated. Treatment outcomes and adverse events were evaluated using propensity score matching (PSM), and risk factors for mortality from UGIB were investigated using Cox multivariate analysis. RESULTS: The sedation group was significantly younger, composed of a higher proportion of males, and had chronic liver disease. Blood pressure and hemoglobin level on admission were significantly higher in the sedation group. The main cause of bleeding was peptic ulcer, which was significantly higher in the nonsedation group. PSM created 133 matched pairs. The success rate of endoscopic hemostasis was similar in both groups, and procedure time was significantly shorter in the sedation group than in the nonsedation group (17.6 ± 10.0 versus 20.2 ± 10.2 min, P = 0.04). There were no significant differences in adverse events between groups. Cox multivariate analyses revealed that red blood cell transfusion [hazard ratio (HR) 4.45, P < 0.02] and rebleeding (HR 3.30, P = 0.03) were associated with increased risk of 30-day mortality from UGIB. CONCLUSIONS: Sedation reduced the procedure time during emergency endoscopy for UGIB. Sedation during emergency endoscopy for UGIB is acceptable for safe endoscopic procedures.

RESUMO

BACKGROUND: This study aimed to evaluate the usefulness of discharge standards in outpatients undergoing sedative endoscopy by comparing the modified post-anesthetic discharge scoring system (MPADSS) and the modified Aldrete score. METHODS: We prospectively enrolled 376 outpatients who underwent gastrointestinal endoscopy under midazolam sedation; 181 outpatients were assessed regarding discharge after sedative endoscopy using the MPADSS (group M), and 195 patients were assessed by the modified Aldrete score (group A). The clinical characteristics, types of endoscopy, endoscopic outcomes, and anesthesia outcomes were evaluated between the two groups. We compared discharge score, recovery time, and adverse events using propensity-score matching. RESULTS: Propensity-score matching created 120 matched pairs. The proportion of patients who had a recovery time within 60 min after endoscopy was significantly higher in group A than that in group M (42.5% versus 25.0%, respectively; P < 0.01). The proportion of patients who required > 120 min of recovery time after endoscopy was significantly lower in group A than that in group M (0.0% versus 5.0%, respectively; P = 0.03). However, significantly more patients had drowsiness at discharge in group A compared with group M (19.1% versus 5.0%, respectively; P < 0.01). There was no significant difference in the adverse event rate within 24 h of discharge between the groups. CONCLUSIONS: Patients assessed by the modified Aldrete score were allowed to discharge earlier than those assessed by the MPADSS. However, a patient's level of consciousness should be assessed carefully, especially in patients who visit the hospital alone.

RESUMO

An 86-year-old woman presented with a history of endoscopic papillary sphincterotomy for bile duct stones and diverticulitis. The patient was admitted as an emergency case of acute cholangitis due to choledocholithiasis, underwent endoscopic bile duct stenting, and was discharged with a plan for endoscopic lithotripsy. One month later, the patient was readmitted owing to abdominal pain. Abdominal computed tomography at admission showed that the bile duct stent had migrated to the sigmoid colon and the presence of a small amount of extraintestinal gas, suggesting a colonic perforation. Lower gastrointestinal endoscopy showed adhesions and intestinal stenosis in the sigmoid colon, probably after diverticulitis, and the bile duct stent that had perforated the same site. The stent was removed and endoscopic closure of the perforation was performed using an over-the-scope clip. Abdominal computed tomography 8 days after the closure showed no extraintestinal gas. The patient resumed eating and was discharged on the 14th day of admission. There was no recurrence of abdominal pain. Endoscopic closure of sigmoid colon perforation due to bile duct stent migration using an over-the-scope clip has not been reported thus far, and it may be a new treatment option in the future.
