This study confirms that the OAGB is an effective procedure for morbid obesity with comparable outcomes to RYGB; in addition, it seems to be safer with lower morbidity. Its technical simplicity represents a real advantage and makes it an option that should be considered by all bariatric surgeons.

Prophylactic treatment after initial decompression of SV results in a low rate of recurrence. Planned sigmoid resection is safe and effective. In frail elderly patients, PEC is satisfactory.

Emergency decision-making after caustic injuries can rely on CT alone.

Emergency CT outperforms endoscopy in predicting esophageal stricture formation after caustic ingestion. Emergency endoscopy evaluation after caustic ingestion is not indispensable.

Operated acute DeBakey type I aortic dissection has to be considered as a chronic aortic disease with the potential of late distal dilatation with aneurysm formation and need for reoperation. Several intraoperative strategies have been devised to prevent late complications. However, the increased operative risk associated with a more aggressive initial approach in an emergent setting has to be balanced against the relatively low incidence of late reoperations. Further studies will have to identify preoperative risk factors for late distal aortic complications more precisely in order to select patients who might benefit the most from these newer surgical strategies.
