Each finding was present more frequently on AUS than AXR. On AUS, pneumatosis and focal fluid collection were independently associated with a longer antibiotic course (4.1 days longer, p=0.03, and 21.3 days longer, p less then 0.001, respectively). CONCLUSIONS Abdominal sonography holds promise as a useful adjunct to radiography for neonates with possible NEC. It may be more sensitive for the presence or absence of bowel ischemia and can reveal findings not detectable by radiograph that may aid provider decision-making. BACKGROUND Elderly patients (65 years of age and older) undergo an increasing number of operations performed annually in the US and they present with unique healthcare needs. Preventing postoperative readmission remains an important challenge to improving surgical care. This study examined whether geriatric-specific variables were independently associated with postoperative readmissions of elderly patients. METHODS The American College of Surgeons (ACS) Geriatric Surgery Research File (GSRF) was joined with the ACS NSQIP Participant Use Data Files for 2014 to 2016. This data set included 13 GSRF variables and 26 ACS NSQIP variables. Associations between clinically relevant variables and readmission were tested with multivariable logistic regression. RESULTS The data represented 6,039 general surgery patients age 65 years and older. Fifty-eight percent of patients had colorectal operations, 19% pancreatic or hepatobiliary, 15% hernia, 4% thyroid or esophageal, and 3% had appendix operations. Twenty-four percen of the relationship between clinical variables and readmissions in elderly surgical patients. BACKGROUND Intraoperative drain use for pancreatoduodenectomy (PD) has been practiced in an unconditional, b
