Because endoscopic ultrasound-guided tissue acquisition (EUS-TA) allows tissue sample obtention from the digestive tract lumen, a biopsy without the intervention of ascites may prevent adverse events (AEs). This study aimed to evaluate the safety of EUS-TA for focal liver lesions in the presence of ascites. <b>Patients and methods</b> A retrospective study was conducted using medical records of cases in which EUS-TA was performed on focal liver lesions between 2016 and 2022. Study participants were classified into two groups: those with ascites and those without it, and the outcomes were compared. The primary outcome was AEs. <b>Results</b> We included 109 cases of EUS-TA for focal liver lesions. Ascites was present in 20.1% of cases (22/109) and absent in 79.8% of cases (87/109). There were no significant differences between the two groups in clinical backgrounds and EUS-TA procedure, although fine-needle biopsy needles were significantly more frequently used in patients without ascites. In the ascites group, puncture without intervening ascites was successful in 90.9% of cases (20/22). The incidence of AEs was 4.5% (1/22) in the ascites group and 1.1% (1/87) in the non-ascites group, showing no significant difference. The two AEs were mild self-limiting abdominal pain. <b>Conclusions</b> In focal liver lesions with ascites, EUS-TA allows biopsy without the intervention of ascites in most cases.

Post-colonoscopy colorectal cancer (PCCRC) and post-endoscopy upper gastrointestinal cancer (PEUGIC) audits have identified missed diagnoses that are associated with harm and require consideration of DoC. This article explores the new and unique challenges associated with DoC in endoscopy audits.

Fear of institutional and personal reputational damage, as well as future litigation, may influence decisions.
