Background And Objectives: Solid pseudopapillary tumors of the pancreas are rare and occur most frequently in young women. They have an uncertain pathogenesis and unclear clinical behavior. Our aim was to evaluate the clinical presentation of solid pseudopapillary tumors and assess the efficacy of treatment with minimally invasive surgery.

The aim of this study was to investigate experimental conditions for efficient and controlled in vivo liver tissue ablation by magnetic resonance (MR)-guided high-intensity focused ultrasound (HIFU) in a swine model, with the ultimate goal of improving clinical treatment outcome. Histological changes were examined both acutely (four animals) and 1 wk after treatment (five animals). Effects of acoustic power and multiple sonication cycles were investigated.

Laparoscopic surgery (LS) for resectable adrenocortical carcinoma (ACC) has been questioned due to uncertainty with regard to long-term oncological outcome. We analyzed the experience with LS compared to open surgery (OS) at Oslo University Hospital (OUH). Material and methods.

Article Synopsis
  • The study evaluated the effectiveness and safety of laparoscopic surgery (LS) for pancreatic neuroendocrine tumors (PNET) at a single hospital over a 14-year period.
  • Out of 72 patients, the procedures had a median surgical time of 175 minutes, with a 42% overall morbidity rate and a 90% five-year disease-specific survival rate.
  • Results indicated that laparoscopic enucleations had a higher risk of postoperative pancreatic fistula, but overall, laparoscopic surgery for PNETs is considered feasible with a positive long-term prognosis.

Background: The role of laparoscopic resection in patients with pancreatic cancer remains to be clarified, because previous reports have not clearly defined oncologic outcomes. The objective of the present study was to investigate this question with the rate of R0 resection and long-term survival as endpoints.

Methods: This retrospective observational study included prospectively collected data from 40 patients operated laparoscopically with curative intent for exocrine pancreatic malignancies identified among 250 consecutive patients undergoing laparoscopic pancreatic operations since 1997.
