ReviewOral refeeding after onset of acute pancreatitis: a review of literature.
Oral refeeding in patients recovering from acute pancreatitis may cause pain relapse. Patients with pain relapse may be ill for prolonged periods, thereby consuming additional health care resources. We aimed to determine the incidence and risk factors of pain relapse on the basis of reviewing all studies on oral refeeding in acute pancreatitis. ⋯ The incidence of pain relapse after oral refeeding in acute pancreatitis is relatively high. Thereby, the quest for new therapeutical modalities that can prevent pain relapse is of current importance.

We performed a systematic review to examine the diagnostic yield (endoscopic and histologic) of esophagogastroduodenoscopy (EGD) for the evaluation of abdominal pain of unclear etiology in children. We also examined the effect of EGD on change in treatment, quality of life, change in abdominal pain, and cost-effectiveness. ⋯ The diagnostic yield of EGD in children with unclear abdominal pain is low; however, existing studies are inadequate. The effect of EGD on change in treatment, quality of life, improvement of abdominal pain, and cost-effectiveness is unknown. The predictors of significant findings are unclear. Our findings suggest that a large multicenter study examining clinical factors, biopsy reports, and addressing patient outcomes is needed to further clarify the value of EGD in children with abdominal pain.

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.

Over one-third of patients with Crohn's disease (CD) will develop an intestinal stricture and the great majority of these will require at least one surgical procedure. While the pathogenesis of inflammation in CD has been extensively investigated, knowledge of stricture pathogenesis remains limited. The aim of this review is to discuss the current understanding of fibrogenesis in CD and to outline potential directions in research and therapeutics. ⋯ Greater understanding of the biology of fibrostenosis is likely to yield significant advances in our ability to care for patients with stricturing CD. Potential dividends of this approach include identification of novel therapeutic targets and biomarkers useful for prognostication and therapeutic monitoring.
