Purpose: This study aims to identify predictors of discharge to post-acute care in geriatric emergency general surgery (EGS) patients.

Methods: This is a retrospective study of geriatric emergency general surgery (EGS) patients at a tertiary care facility between 2017 and 2018. Inclusion criteria were ≥ 65 years old and presented directly from home.

Background: Intraoperative adverse events (iAEs) during general surgery can lead to significant morbidity and healthcare burden, yet their impact remains underexplored. We aimed to estimate the nationwide incidence of iAEs in general surgery and explore their associations with mortality, complications, length of stay, and costs.

Methods: We conducted a retrospective cohort study using the Nationwide Readmissions Database 2019 and included adult patients (aged 18 years and older) who underwent general surgical procedures.

Background: The impact of tracheostomy timing on outcomes is unclear in geriatric patients with traumatic brain injury (TBI).

Methods: Patients aged≥65 with isolated severe TBI who underwent tracheostomy were identified in the ACS-TQIP 2017-2020 database. Patients were grouped by early (<10 days) vs.

Background: The prolonged use of percutaneous cholecystostomy tubes (PCTs) in patients with acute cholecystitis, deemed inoperable, is fraught with complications. Transpapillary cholecystoduodenal stenting (TCDS) is an alternative technique that restores the physiologic outflow of bile, avoiding the need for an external drain. However, the long-term safety and efficacy of this approach remain unclear.

Background: The POTTER calculator, a widely used interpretable artificial intelligence (AI) risk calculator, has been validated in population-based studies and shown to predict outcomes in emergency general surgery (EGS) patients better than surgeons. We sought to prospectively validate POTTER.

Study Design: Patients undergoing an emergency exploratory laparotomy for non-trauma indications at two Academic Medical Centers between June 2020 and March 2022 were included.
