Review Meta AnalysisDoes enteral nutrition affect clinical outcome? A systematic review of the randomized trials.
Both parenteral nutrition (PN) and enteral nutrition (EN) are widely advocated as adjunctive care in patients with various diseases. A systematic review of 82 randomized controlled trials (RCTs) of PN published in 2001 found little, if any, effect on mortality, morbidity, or duration of hospital stay; in some situations, PN increased infectious complication rates. ⋯ There is strong evidence for not using EN in the first week in dysphagic, and not using VNS at all in nondysphagic, stroke patients who are not malnourished. There is reasonable evidence for using VNS in malnourished geriatric patients. The recommendations to consider EN/VNS in perioperative/liver/critically ill/low birth weight patients are limited by the low quality of the RCTs. No evidence could be identified to justify the use of EN/VNS in other disease states.

Review Meta AnalysisNeurolytic celiac plexus block for pain control in unresectable pancreatic cancer.
A major focus of palliation in patients with unresectable pancreatic cancer is pain control. The aim of this systematic review was to examine the efficacy and safety of neurolytic celiac plexus blockade (NCPB) compared with standard treatment in randomized controlled trials (RCTs) involving patients with unresectable pancreatic cancer. ⋯ In patients with unresectable pancreatic cancer, NCPB is associated with improved pain control, and reduced narcotic usage and constipation compared with standard treatment, albeit with minimal clinical significance.
