Endovascular therapy with thrombolysis using tissue plasminogen activator remains an effective treatment option for patients presenting with mild or moderate lower extremity ALI, with equal benefit derived with CDT or PMT. Patients with end-stage renal disease or poor pedal outflow have an increased risk of limb loss and may benefit from alternative revascularization strategies.

In patients presenting with class II ALI, ER or surgical OR resulted in comparable limb salvage rates. Although technical success is higher with OR for patients presenting with failed bypass grafts, the amputation rates are comparable. Overall mortality rates are significantly higher at 30 days and 1 year in the OR group.

Neuroendocrine tumors, or carcinoid tumors, of both the midgut and hindgut are quite rare, but their incidence is increasing. Surgery is the treatment of choice in patients who can tolerate an operation and have operable disease. Options for the treatment of metastatic disease include cytoreductive surgery, somatostatin analogues, interferon α, local liver therapies (hepatic arterial embolization, ablation), chemotherapy, Peptide-Receptor Radionucleotide Radiotherapy, angiogenesis inhibitors, and mammalian target of rapamycin inhibitors.

Gastrointestinal stromal tumors (GISTs) are rare in occurrence, but comprise the most common mesenchymal tumors of the gastrointestinal tract and affect between 15 and 20 individuals per million per year. Due to recent advancements in molecular classification of these tumors, medical therapy has provided improved outcomes to a historically surgically managed disease. This review article briefly discusses the molecular characteristics, medical and surgical therapies, and future of GIST management.
