Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Closure of gastrojejunostomy	time needed to perform this specific surgical step, i.e. the ventral defect closure of the (otherwise stapled) gastrojejunostomy	The assessment of this surgical step will be completed during the operation.
Secondary	anastomotic site perioperative morbidity	Number of participants with hemorrhage, leakage or symptomatic strictures requiring further diagnostic or therapeutic measurements	6 months
Secondary	other anastomosis- related morbidity	Number of participants with marginal ulcer or anastomotic stricture needing further diagnostic and/or interventions	6 months
Secondary	economical factors	costs of treatment in case the above mentioned complications occur and require intervention	6 months
