Pre-operative intravenous feeding--a controlled trial

Area of Science:

• Oncology
• Surgical Nutrition
• Gastroenterology

Background:

• Pre-operative nutritional status is crucial for patients undergoing surgery for upper gastrointestinal cancers.
• Intravenous nutrition is a potential method to improve outcomes in these vulnerable patients.

Purpose of the Study:

• To evaluate the efficacy of a short course of pre-operative intravenous nutrition in patients with stomach or oesophageal cancer.
• To assess the impact of this nutritional intervention on clinical outcomes and immune/biochemical profiles.

Main Methods:

• A randomized, controlled clinical trial involving 74 patients with pre-operative stomach or oesophageal cancer.
• Intervention group received 7-10 days of pre-operative intravenous nutrition.
• Outcomes were monitored through clinical course, immune, and biochemical profiles.

Main Results:

• Pre-operative parenteral nutrition led to a significant decrease in postoperative wound infections.
• Clinical benefits were primarily observed in patients with low pre-admission serum albumin levels.
• No significant improvements were noted for other patient subgroups.

Conclusions:

• Short-term pre-operative intravenous nutrition can reduce wound infections in upper gastrointestinal cancer patients.
• The benefits are concentrated in malnourished patients (low serum albumin).
• Routine use is questionable due to limited overall clinical benefit and potential hazards.
