Introduction: Nearly 20% of ventral hernia repair (VHR) patients require a subsequent abdominal operation (SAO), and mesh position may impact the complexity and outcome of the SAO.
Methods: Retrospective review of VHR with mesh from 2006 to 2020 from an internal database and the ACHQC. Primary outcomes measured incidence, complexity, and complications of SAO relative to mesh position.
Results: SAO was required in 433 of 2539 (17.1%) patients, totaling 671 operations; 197/893 (22.1%) with intraperitoneal mesh (IPM) and 236/1646 (14.3%) with extraperitoneal mesh (EPM; p < 0.001). SAO was directly related to VHR in 180 (232 total SAOs) and unrelated in 253 (439 total SAOs). There were no significant differences in complications after SAO between IPM and EPM, nor any difference in adhesion complexity.
Conclusion: Incidence of SAO is higher with IPM, but surgical outcomes are similar. Due to the risk of secondary mesh infection with IPM, significantly more of these were removed at the time of SAO.

An a (AEF) is a rare but life-threatening condition where an abnormal connection forms between the aorta and the gastrointestinal tract, most commonly the duodenum. It can be primary (arising spontaneously due to an aortic aneurysm or infection) or secondary (complicating prior vascular surgery). Immediate recognition and surgical intervention are critical to manage severe gastrointestinal bleeding and prevent fatal outcomes.

Objectives: The aim of this study was to assess the impact of an iterative metal artifact reduction (iMAR) algorithm combined with virtual monoenergetic images (VMIs) for artifact reduction in photon-counting detector computed tomography (PCDCT) during interventions.
Materials And Methods: Using an abdominal phantom, we conducted evaluations on the efficacy of iMAR and VMIs for mitigating image artifacts during interventions on a PCDCT. Four different puncture devices were employed under 2 scan modes (QuantumSn at 100 kV, Quantumplus at 140 kV) to simulate various clinical scenarios.

Background: Image-defined risk factors (IDRFs) were introduced to provide a consensus approach for pre-treatment risk stratification on computed tomography (CT) and magnetic resonance imaging (MRI) in patients with neuroblastoma.
Objective: To assess the intra- and inter-reader agreement of radiologists in identifying IDRFs on CT.
Materials And Methods: Approval for this retrospective study was granted by our institutional research ethics board with a waiver of consent.

Introduction: Succinate dehydrogenase subunit B (SDHB)-mutated paragangliomas (PGLs) are rare neuroendocrine tumors characterized by increased malignancy, readily metastasizing, and poorer prognosis. Here we report a case of SDHB-mutated metastatic PGL, wherein the patient showed significant tumor shrinkage and complete symptom remission following chemotherapy. We aim to contribute additional evidence to the existing knowledge associated with SDHB-mutated PGLs.

Background: Abdominal pain is the cardinal symptom of acute pancreatitis (AP), often requiring opioid therapy. This study aimed to investigate the dose-dependent relationship between opioid therapy and moderately severe or severe AP.
Methods: This was a post-hoc analysis of the prospective PAINAP database, which recruited patients with first-time AP from 118 centres across 27 countries between April-June 30, 2022.
