RESUMO
Background and objectives: The safety of electrohydraulic lithotripsy (EHL) in older adults remains unclear. We aimed to investigate the efficacy and safety of EHL using peroral cholangioscopy (POCS) under endoscopic retrograde cholangiopancreatography (ERCP) guidance in older adults aged ≥80 years. Materials and Methods: This retrospective clinical study was conducted at a single center. Fifty patients with common bile duct stones who underwent EHL using POCS under ERCP guidance at our institution, between April 2017 and September 2022, were enrolled in this study. The eligible patients were divided into an elderly group (n = 21, age ≥80 years) and a non-elderly group (n = 29, age ≤79 years), and were analyzed. Results: A total of 33 and 40 EHL procedures were performed in the elderly and non-elderly groups, respectively. After excluding cases in which stone removal was performed at other institutions, complete removal of common bile duct stones was confirmed in 93.8% and 100% of the elderly and non-elderly groups, respectively (p = 0.20). The mean number of ERCPs required for complete removal of bile duct stones was 2.9 and 4.3 in the elderly and non-elderly groups, respectively (p = 0.17). In the EHL session, the overall occurrence of adverse events was eight and seven in the elderly (24.2%) and non-elderly (17.5%) groups, respectively; however, the difference was insignificant (p = 0.48). Conclusions: EHL using POCS under ERCP guidance is effective in patients aged ≥80 years and there was no significant increase in adverse event rates compared to those aged ≤79 years.

A 64-year-old woman was diagnosed with emphysematous cholecystitis. An open cholecystectomy was performed immediately. After the cholecystectomy, jaundice and multiple bile duct strictures that were not present preoperatively appeared. The patient was diagnosed with sclerosing cholangitis secondary to emphysematous cholecystitis. Endoscopic biliary stenting and endoscopic biliary balloon dilatation were performed. However, jaundice did not improve. She developed candidemia 75 days after cholecystectomy. The patient died of multiple organ failures 92 days after cholecystectomy. Although rare, secondary sclerosing cholangitis occurred after emphysematous cholecystitis, and endoscopic treatment was ineffective in this case.
RESUMO
AIM: There are few reports on the safety of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in the elderly. In this study, we investigated the safety of EUS-FNA for pancreatic solid masses in patients aged ≥80 years. METHODS: This is a single-center retrospective study. A total of 600 patients with pancreatic solid masses who underwent EUS-FNA under midazolam-based sedation at our institution between September 2016 and December 2022 were enrolled in this study. Eligible patients were divided into two groups: an elderly group aged ≥80 (n = 84), as well as a nonelderly group aged ≤79 (n = 516). These two groups were compared. RESULTS: The elderly group required significantly fewer midazolam doses for sedation (P < 0.001). Adverse events occurred in eight patients (1.3%), including one (1.2%) and seven (1.4%) in the elderly and nonelderly groups, respectively (P = 0.90). There were no cases of early adverse events in the elderly group and six cases (1.2%) in the nonelderly group (P = 0.32). There was one case of late adverse events in both the elderly and nonelderly groups (P = 0.14), and both were needle tract seeding. There was no significant difference between the two groups in the proportion of cases in which percutaneous oxygen saturation decreased to ≤90% during the EUS-FNA. CONCLUSIONS: Our analysis suggests that EUS-FNA for pancreatic solid masses can be safely performed in patients aged >80 years without increasing the adverse event rate compared to nonelderly patients aged <80 years.

In the past decade, it has increasingly been reported that epigallocatechin-3-gallate (EGCG), a major catechin derivative extracted from Green tea, has various bioactivities, including a cell-protective action on mammalian cells and tissues. In this study, we have tested a commercial preservation solution containing EGCG (Theliokeep(®)) in both two- and three-dimensional cultures of human periosteal sheets, which have been used as an osteogenic grafting material for periodontal regenerative therapy. When periosteal sheets were 3D-cultured on collagen mesh, cell viability was maintained for 2 days using the hypothermic EGCG preservation solution. Replenishment of EGCG solution with 2-day intervals prevented the time-dependent decline in cell viability at 3 days and later. As observed in nonpreserved control cultures, most cells were positive for proliferating cell-nuclear antigen (PCNA) in the cultures preserved at 4°C in the EGCG solution, whereas PCNA-negative cells were increased in the cultures preserved at 4°C in the MesenPRO medium. In periosteal sheets 2D-cultured in plastic dishes, the EGCG solution occasionally was associated with vacuole formation in the cytoplasm, but cells could again expand in the culture medium at 37°C. As observed in the nonpreserved periosteal sheets control, the osteogenic induction upregulated alkaline phosphatase in those cells and tissues preserved in the EGCG solution. The EGCG solution protected cells from the cold shock-induced membrane phospholipid peroxidation. Our data suggest that the EGCG solution acts as an antioxidant to protect periosteal cells from cold shock and preserves cells under chilled conditions. The limited period of preservation time could be expanded by repeating replenishment of the EGCG solution or by optimizing the formula to be more favorable for human periosteal sheets without sacrificing cell viability. This methodology of preserving human cultured periosteal sheets with EGCG would be expected to support and spread the clinical use of regenerative therapy with autologous periosteal sheets.
