Dear Dr Taha

I usually start to feeding as soon as possible with limited soft diet (no residual ) on second day and when patient tolerates it, i will advance the diet.

patient is forbidden to drink or eat sweets because of dumping syndrome 

and recommend to eat low volume of food without water or liquid during in meals.

We start as soon as the patient is comfortable....preferably day 3 and 4 provided the ptnts rt tube is not draining much and has a soft abdomen.we usually clip the ryles tube and start giving plain clear fluids and slowly advance it to semi solid diets over a week...in cases where an fj is done we start fj feed with clear fluids on day 2....500ml/o ver 12 hrs and then switch over to fj feed with home based fluids like rice water or coconut water and then slowly into formulations with higher concentran

The same idea of fast nutrition   after bariatric MGB and RYGB is equal in oncologic   gastric  surgery.  Clear Fluid on 2.day or   after RTG control  of  anastomosis. Semi   solids after 6-8 days .Solids after 14 days.

We are slightly more conservative after total gastrcetomy than sub total. The latter group can be managed in a similar way to bariatrics which is relatively early initiation of free fluids (day 1-2) and then soft diet from day 3 onwards. For total gastretomies we still perform contrast radiology swallow on day 4 before initiating diet although i accept that the evidence for this is somehwat conflicting
