The purpose of this study is to determine preoperative factors that are predictive of malignancy in patients undergoing pancreatic resection for intraductal papillary mucinous neoplasms (IPMN). ⋯ In agreement with current IPMN management guidelines, we found MPD dilatation, even low levels from 5 mm to 9.9 mm, to be the single best predictor of HG-IPMN or invasion, highlighting the critical role that MPD plays in the selection of surgical candidates.

Multicenter Study
Yield of Screening for COVID-19 in Asymptomatic Patients Prior to Elective or Emergency Surgery Using Chest CT and RT-PCR (SCOUT): Multicenter Study.
To determine the yield of preoperative screening for COVID-19 with chest CT and RT-PCR in patients without COVID-19 symptoms. ⋯ One in every 100 patients without COVID-19 symptoms tested positive for SARS-CoV-2 with RT-PCR; this yield increased in conjunction with community prevalence. The added value of chest CT was limited. Preoperative screening allowed us to take adequate precautions for SARS-CoV-2 positive patients in a surgical population, whereas negative patients needed only routine procedures.

Laparoscopic Liver Transplantation: Dream or Reality? The First Step With Laparoscopic Explant Hepatectomy.
To introduce the laparoscopic approach in liver transplant recipients. ⋯ This case study suggests that the hybrid approach may be feasible and safe in selected recipients. The decision to use this surgical approach should be made in transplant centers with significant expertise in both laparoscopic liver and pancreatic surgery. Further reducing the size of the abdominal incision is the next step, which may be achieved with the development of vascular anastomoses devices.

This retrospective cohort study examined whether bariatric surgery is associated with reduced risk of breast cancer among pre- and postmenopausal women. ⋯ Bariatric surgery was associated with a reduced risk of breast cancer among severely obese women. These findings have significant public health relevance because the prevalence of obesity continues to rise, and few modifiable breast cancer risk factors have been identified, especially for premenopausal women.

Observational Study
Influence of Preoperative Oropharyngeal Microflora on the Occurrence of Postoperative Pneumonia and Survival in Patients Undergoing Esophagectomy for Esophageal Cancer.
The aim of this study was to clarify the correlation between oropharyngeal microflora and postoperative complications as well as long-term survival after esophagectomy. ⋯ Preoperative oropharyngeal culture is a simple and low-cost method that can predict both the occurrence of postoperative pneumonia and poor prognosis after esophagectomy.
