Role of ablation therapy in conjunction with surgical resection for neuroendocrine tumors involving the liver.

Background: Resection of hepatic metastasis from neuroendocrine tumors (NETs) improves quality of life and prolongs 5-year survival. Ablation can be utilized with surgery to achieve complete resection. Although several studies report long-term outcomes for patients undergoing ablation, none have explored perioperative effects of ablation in patients with metastatic NETs.

Post-operative morbidity after neoadjuvant chemotherapy and resection for gallbladder cancer: A national surgical quality improvement program analysis.

Background: Gallbladder cancer is the most common malignancy of the biliary tract. Neoadjuvant chemotherapy (NACT) has improved overall survival by enabling R0 resection. Currently, there is no consensus of guidelines for neoadjuvant therapy in gallbladder cancer.

Radiation therapy prior to a pancreaticoduodenectomy for adenocarcinoma is associated with longer operative times and higher blood loss.

Background: Pancreatic adenocarcinoma is currently the fourth leading cause of cancer-related deaths in the United States. In patients with "borderline resectable" disease, current National Comprehensive Cancer Center guidelines recommend the use of neoadjuvant chemoradiation prior to a pancreaticoduodenectomy. Although neoadjuvant radiotherapy may improve negative margin resection rate, it is theorized that its administration increases operative times and complexity.

Antibacterial Effect of Acoustic Cavitation Promoted by Mesoporous Silicon Nanoparticles.

As-prepared mesoporous silicon nanoparticles, which were synthesized by electrochemical etching of crystalline silicon wafers followed by high-energy milling in water, were explored as a sonosensitizer in aqueous media under irradiation with low-intensity ultrasound at 0.88 MHz. Due to the mixed oxide-hydride coating of the nanoparticles' surfaces, they showed both acceptable colloidal stability and sonosensitization of the acoustic cavitation.

Concurrent major hepatic resection with primary colorectal cancer increases risk of organ space infections.

Introduction: Patients with colorectal cancer frequently present with liver metastases requiring either concurrent colon and liver resection or staged resection for curative therapy. The goal of this study is to determine if synchronous resection increases risk of perioperative adverse outcomes such as surgical site infections (SSIs).

Methods And Procedures: We conducted a cross-sectional retrospective analysis of the targeted hepatectomy NSQIP database from 2015 to 2019.
