This study shows that the larger the sinus ostium, the better the penetration of irrigant into the sinus, with an ostium of at least 4.7 mm allowing maximal penetration in the maxillary and sphenoid sinuses. The same benefit was not noted in the frontal sinus. Head position was only relevant to the frontal sinus where less penetration was seen with the head neutral (vertex to ceiling) position when compared to forward angled positions.

Obesity is independently associated with reduced inhospital mortality in patients with SSTI regardless of the obesity classification. This suggests that the obesity paradox exists in this acute surgical population.

This study describes current practice patterns of VTE screening and prophylaxis in high-risk bariatric surgery. Nearly all surgeons agree on risk factors that qualify patients as high risk, but only half routinely screen patients preoperatively. Preoperative VTE chemoprophylaxis is used by nearly all surgeons, but the duration of therapy varies. Use of IVC filters is not routine, and postoperative screening was performed by less than half of the respondents. An understanding of current practice patterns yields insight into the rates of VTE and shows variability in the need for evidence-based prophylaxis and standardized screening.
