Intraoperative radiotherapy with the Intrabeam device for the treatment of resectable pancreatic adenocarcinoma.

Introduction: The application of intraoperative radiation therapy to the tumor bed after resection of pancreatic cancer has been shown to be beneficial in the local control of the disease. The objective of this study was to evaluate the preliminary outcomes after the application of a single intraoperative dose to the tumor bed with a new intraoperative radiotherapy device (Intrabeam) in terms of viability, safety and short-term results.

Methods: We studied 5 patients who underwent pancreaticoduodenectomy for resectable pancreatic cancer in which a radiotherapy boost (5Gy) was intraoperatively applied to the tumoral bed using the portable Intrabeam device, a low-energy point-source X-ray.

Obesity Surgery Score (OSS) for Prioritization in the Bariatric Surgery Waiting List: a Need of Public Health Systems and a Literature Review.

Background: In the last decades, we have experienced an increase in the prevalence of obesity in western countries with a higher demand for bariatric surgery and consequently prolonged waiting times. Currently, in many public hospitals, the only criterion that establishes priority for bariatric surgery is waiting time regardless of obesity severity.

Methods: We propose a new, simple, and homogeneous clinical prioritization system, the Obesity Surgery Score (OSS), which takes into account simultaneously and equitably the time on surgical waiting list and the obesity severity based on three variables: body mass index, obesity-related comorbidities, and functional limitations.

[Predictive factors of massive intestinal necrosis in acute mesenteric ischemia].

Introduction: Suspicion of intestinal necrosis in patients with mesenteric ischemia is mandatory in surgery. Many patients develop massive necrosis after open surgery. However, in some frail, elderly patients, preoperative prediction of massive intestinal necrosis could avoid an unnecessary laparotomy.
