Diet Recommendations After Endoscopic Full-Thickness Resection (EFTR) in the Stomach

Initial Diet Progression

Patients should begin with clear liquids at room temperature for the first 24-48 hours post-procedure, gradually increasing volume to reach approximately 2 liters per day 1
Consume liquids in small portions (no more than half a cup per serving) to prevent distension of the surgical site 1
Progress to full liquids including milk, soy drinks, and plain yogurt at 3-7 days post-procedure 1
Advance to pureed or mashed foods at 1-2 weeks post-procedure 1
Introduce soft foods (e.g., soft meatballs, scrambled eggs, cooked vegetables, soft fruits) at 2 weeks post-procedure 1
Progress to solid foods including legumes, fresh vegetables, fresh fruits, and bread at approximately 1 month post-procedure 1

Separate liquids from solids by avoiding drinking beverages 15 minutes before or 30 minutes after eating to prevent distension and discomfort 1, 2
Plan and arrange frequent small meals throughout the day (4-6 meals daily) according to the post-procedural stage 3
Eat slowly and methodically chew food thoroughly to prevent complications 3
Avoid carbonated beverages which can cause bloating and discomfort 2, 3

Ensure thorough mastication (chew each bite at least 15 times) and eat slowly (wait a minute between swallows) to prevent dysphagia 3
Avoid hard and dry foods such as toast or overcooked meat that may be difficult to swallow 3
Take small bites, chew thoroughly, and eat slowly with meal duration of at least 15 minutes to prevent vomiting 3
Space meals at intervals of at least 2-4 hours to prevent vomiting 4

Reduce fat consumption and customize menus accordingly to manage potential diarrhea and flatulence 3
Ensure adequate fluid intake of at least 1.5 L/day to manage potential diarrhea and flatulence 3
Avoid gas-producing foods such as cauliflower and legumes to manage potential diarrhea and flatulence 5
Avoid chewing gum which can lead to aerophagia to manage potential diarrhea and flatulence 5

Ensure adequate protein intake to support healing 1
