Resuming Diet After Appendectomy

Immediate Postoperative Feeding Protocol

The American Society for Parenteral and Enteral Nutrition recommends beginning oral intake with clear liquids within hours after appendectomy and advancing to a regular solid diet as tolerated on the same day or first postoperative day, with no need to wait for bowel sounds or flatus 1, 2
Oral nutritional intake should be continued after surgery without interruption in most instances, with evidence strongly supporting early feeding after appendectomy 1
Patients should start clear liquids at room temperature within hours of surgery, gradually increasing volume as tolerated 1, 2
Patients can progress directly to regular solid food as soon as they desire, without the need for traditional stepwise advancement through full liquids and soft diets 1, 2

Meta-analyses show that early postoperative oral feeding is associated with significant reductions in total complications, shorter hospital stays, and earlier return of bowel function without increasing anastomotic dehiscence, mortality, or need for nasogastric tube reinsertion 1, 2

The American College of Nutrition recommends small meals five to six times per day to help patients tolerate oral feeding and achieve nutritional goals faster during early recovery 1, 2
Oral intake should be adapted according to individual tolerance, with special attention to elderly patients, and clear liquids can be advanced immediately to regular food if well tolerated within the first few hours 1, 2
Most patients can consume regular solid food on the day of surgery or first postoperative day, with no requirement to wait for bowel sounds, flatus, or bowel movements before feeding 1, 2
