Is routine postoperative enteral feeding after oesophagectomy worthwhile?

Area of Science:

• Surgical Oncology
• Gastroenterology
• Critical Care Medicine

Background:

• Oesophagectomy for cancer necessitates careful postoperative management.
• Early nutritional support is crucial for recovery, but optimal timing and method remain debated.
• Enteral feeding via jejunostomy or nasojejunostomy is an option for immediate postoperative nutrition.

Purpose of the Study:

• To evaluate the efficacy of immediate postoperative enteral feeding versus delayed oral feeding in patients undergoing oesophagectomy for cancer.
• To compare patient outcomes, including length of stay, complications, and mortality.

Main Methods:

• A systematic review of four randomized controlled trials (RCTs) was conducted.
• Studies compared immediate enteral feeding (jejunostomy or nasojejunostomy) with routine diet or delayed feeding.
• Outcomes assessed included anastomotic complications, mortality, length of stay, and catheter-related issues.

Main Results:

• No statistically significant differences were found in length of stay, anastomotic complications, or mortality between early enteral feeding and control groups.
• Some studies reported no clinical benefits of early enteral feeding, with one noting decreased pulmonary function in fed patients.
• Mortality was higher in one jejunostomy group, though not directly attributed to the feeding method.

Conclusions:

• Routine immediate postoperative enteral nutrition following oesophagectomy is feasible but does not confer significant clinical benefits.
• Current evidence does not support the routine use of early enteral feeding in patients without preoperative malnutrition.
• Further research may be needed to identify specific patient subgroups who might benefit from early enteral nutrition.
