Results: Of 23,744 patients presenting with AMI, 4665 underwent interventional treatment from 2005 through 2009. Of these patients, 57.1% were female, and the mean age was 70.5 years. A total of 679 patients underwent vascular intervention; 514 (75.7%) underwent open surgery and 165 (24.3%) underwent endovascular treatment overall during the study period. The proportion of patients undergoing endovascular repair increased from 11.9% of patients in 2005 to 30.0% in 2009. Severity of comorbidities, as measured by the Charlson index, did not differ significantly between the treatment groups. Mortality was significantly more commonly associated with open revascularization compared with endovascular intervention (39.3% vs 24.9%; P = .01). Length of stay was also significantly longer in the patient group undergoing open revascularization (12.9 vs 17.1 days; P = .006). During the study time period, 14.4% of patients undergoing endovascular procedures required bowel resection compared with 33.4% for open revascularization (P < .001). Endovascular repair was also less commonly associated with requirement for TPN support (13.7% vs 24.4%; P = .025).
Conclusions: Endovascular intervention for AMI had increased significantly in the modern era. Among AMI patients undergoing revascularization, endovascular treatment was associated with decreased mortality and shorter length of stay. Furthermore, endovascular intervention was associated with lower rates of bowel resection and need for TPN. Further research is warranted to determine if increased use of endovascular repair could improve overall and gastrointestinal outcomes among patients requiring vascular repair for AMI.
One discussion this week included the question of step-up approach versus open necrosectomy for pancreatitis.
BACKGROUND: The 2010 randomized PANTER trial in (infected) necrotizing pancreatitis found a minimally invasive step-up approach to be superior to primary open necrosectomy for the primary combined endpoint of mortality and major complications, but long-term results are unknown.
NEW FINDINGS: With extended follow-up, in the step-up group, patients had fewer incisional hernias, less exocrine insufficiency and a trend towards less endocrine insufficiency. No differences between groups were seen for recurrent or chronic pancreatitis, pancreatic endoscopic or surgical interventions, quality of life or costs.
IMPACT: Considering both short and long-term results, the step-up approach is superior to open necrosectomy for the treatment of infected necrotizing pancreatitis.
A discussion this week included the use of DOTATATE in the surgical management of small bowel neuroendocrine tumors.

Summary: The three most commonly used 68Ga-labeled somatostatin receptor PET imaging agents are 68Ga-DOTATATE, 68Ga-DOTATOC and 68Ga-DOTANOC. Despite the slight variation of the somatostatin receptor affinity of these agents, all of them have shown excellent sensitivity in detection of NETs. At this time, there is no evidence of significant diagnostic superiority of one agent over the others.
