- OBJECTIVE: A systematic review of the nonsurgical treatment of patients with appendiceal abscess or phlegmon, with emphasis on the success rate, need for drainage of abscesses, risk of undetected serious disease, and need for interval appendectomy to prevent recurrence. SUMMARY BACKGROUND DATA: Patients with appendiceal abscess or phlegmon are traditionally managed by nonsurgical treatment and interval appendectomy. This practice is controversial with proponents of immediate surgery and others questioning the need for interval appendectomy. METHODS: A Medline search identified 61 studies published between January 1964 and December 2005 reporting on the results of nonsurgical treatment of appendiceal abscess or phlegmon. The results were pooled taking the potential clustering on the study-level into account. A meta-analysis of the morbidity after immediate surgery compared with that after nonsurgical treatment was performed. RESULTS: Appendiceal abscess or phlegmon is found in 3.8% (95% confidence interval (CI), 2.6-4.9) of patients with appendicitis. Nonsurgical treatment fails in 7.2% (CI: 4.0-10.5). The need for drainage of an abscess is 19.7% (CI: 11.0-28.3). Immediate surgery is associated with a higher morbidity compared with nonsurgical treatment (odds ratio, 3.3, CI: 1.9-5.6, P < 0.001). After successful nonsurgical treatment, a malignant disease is detected in 1.2% (CI: 0.6-1.7) and an important benign disease in 0.7% (CI: 0.2-11.9) during follow-up. The risk of recurrence is 7.4% (CI: 3.7-11.1). CONCLUSIONS: The results of this review of mainly retrospective studies support the practice of nonsurgical treatment without interval appendectomy in patients with appendiceal abscess or phlegmon. © 2007 Lippincott Williams & Wilkins, Inc.

- Objective: To compare the efficacy and safety of early, nasogastric enteral nutrition (EN) with total parenteral nutrition (TPN) in patients with predicted severe acute pancreatitis (SAP). Summary Background Data: In SAP, the magnitude of the inflammatory response as well as increased intestinal permeability correlates with outcome. Enteral feeding has been suggested superior to parenteral feeding due to a proposed beneficial effect on the gut barrier. Methods: Fifty patients who met the inclusion criteria were randomized to TPN or EN groups. The nutritional regimen was started within 24 hours from admission and EN was provided through a nasogastric tube. The observation period was 10 days. Intestinal permeability was measured by excretion of polyethylene glycol (PEG) and concentrations of antiendotoxin core antibodies (Endocab). Interieukins (IL)-6 IL-8, and C-reactive protein (CRP) were used as markers of the systemic inflammatory response. Morbidity and feasibility of the nutritional route were evaluated by the frequency of complications, gastrointestinal symptoms, and abdominal pain. Results: PEG, Endocab, CRP, IL-6, APACHE II score, severity according to the Atlanta classification (22 patients), and gastrointestinal symptoms or abdominal pain did not significantly differ between the groups. The incidence of hyperglycemia was significantly higher in TPN patients (21 of 26 vs. 7 of 23; P < 0.001). Total complications (25 vs. 52; P = 0.04) and pulmonary complications (10 vs. 21; P = 0.04) were significantly more frequent in EN patients, although complications were diagnosed dominantly within the first 3 days. Conclusion: In predicted SAP, nasogastric early EN was feasible and resulted in better control of blood glucose levels, although the overall early complication rate was higher in the EN group. No beneficial effects on intestinal permeability or the inflammatory response were seen by EN treatment.
