Recurrence of adhesive small bowel obstruction (ASBO) can lead to multiple admissions. There is limited knowledge of the role of operative and nonoperative treatment in the long-term recurrence risk for ASBO. We sought to determine the effect of operative and nonoperative management on future ASBO recurrences. ⋯ Operative management for the most recent ASBO is associated with fewer recurrences. Subsequent cumulative recurrences of ASBO predispose to recurrence regardless of operative or nonoperative management. When considering ASBO management, subsequent recurrence should be considered.

Peritoneal carcinomatosis (PC) from pancreatic ductal adenocarcinoma (PDAC) is fatal. Our preclinical study presents an effective treatment against PDAC PC using a novel oncolytic viral agent, CF33-hNIS-antiPDL1. ⋯ CF33-hNIS-antiPDL1 virus is effective in infecting and killing human PDACs and producing functional anti-PD-L1 antibody. Intraperitoneal delivery of CF33-hNIS-antiPDL1 effectively reduces peritoneal tumor burden and improves survival after only 1 dose and is superior to IV delivery.

For patients with sentinel node-positive melanoma (SNPM), randomized trials, first reported in 2015, found no benefit for routine completion lymph node dissection (CLND) in selected patients. This study examines time trends in CLND and explores institutional and clinical factors associated with CLND. ⋯ Completion lymph node dissection in SNPM decreased over time, with the greatest change in 2016. Several patient, pathologic, and institutional characteristics were associated with likelihood of CLND. As evidence supports close observation for selected patients, efforts should be undertaken to improve and standardize patient selection for CLND across institutions caring for patients with melanoma.
