Prophylactic antibiotics are not necessary for elective LC in low-risk patients.

Rounded atelectasis is an increasingly recognized but under-diagnosed and sometimes misdiagnosed pulmonary entity. This pictorial essay will present a broad range of examples of rounded atelectasis across different imaging modalities with inclusion of typical and atypical presentations. These examples will highlight imaging features that allow confident diagnosis and those that warrant further management, such as imaging surveillance, alternate imaging or invasive procedures for histological evaluation.

Background: Dysphagia occurs in up to 50% of patients admitted to hospital with acute strokes with up to 27% remaining by seven days. Up to 8% continue to have swallowing problems six months after their stroke with 1.7% still requiring enteral feeding. Nasogastric tubes (NGT) are the most commonly used method for providing enteral nutrition in early stroke, however they are easily and frequently removed leading to inadequate nutrition, early PEG (Percutaneous Endoscopic Gastrostomy) insertion or abandoning of feeding attempts. Looped nasogastric tube feeding may improve the delivery of nutrition to such patients.
