Control group = standard of Care regimen: 1000ml = 1000 kCal TPN postop from day 1 until day 7. Oral feeds are started from day 5 onwards if no arguments for clinical leak (cervical anastomosis) or barium swallow is normal. Oral intake consists of regular post gastrectomy diet (building up from fluids over semi-solids to solids) with eventually added high nitrogen energy drinks.

Treatment group: start jejunostomy feeds from day 1, with target of 1000ml = 1000kCal (= 40cc/hour). To equilibrate energy intake during build up fase, Glucose 20% is given at a total cumulative dose taking into account the dose of j-drip, cumulative not exceeding 40cc/hr. Oral feeds are started at the same time as in the control group (reg. day 5) Jejunostomy feeds are then continued for 6 weeks together with oral intake with a continuous energy administration of 1000kCal, and then stopped. After this time, patients should be on regular full diet in both groups. If failure and step-back needed, temporary switch to Glc 20% is done to maintain fluid and calory administration.

Target of 1000 kCal/day enteral feeding or glucose 20%, perferably given overnight.
