About this trial
This is an interventional prevention trial for Hemorrhage focused on measuring Gastric bypass, Tranexamic acid
Eligibility Criteria
Inclusion Criteria:
- Primary metabolic procedure;
- Gastric bypass: Roux-en-Y gastric bypass or One-anastomoses gastric bypass;
- ≥18 years;
- Good command of the Dutch or English language.
Exclusion Criteria:
- Patients unwilling to give informed consent;
- Patients with a medical history of bleeding or VTE (defined as, pulmonary embolism (PE) or deep vein thrombosis (DVT));
- Patients who use anticoagulants;
- Arterial bleeding or (iatrogenic) bleeding during the procedure coming from surrounding organs or vascular structures such as the liver or the spleen.

Outcomes
Primary Outcome Measures
re-intervention rate
To compare the re-intervention rate due to haemorrhage within 30 days postoperative, after peroperative administration of TXA versus placebo in patients receiving a RYGB or OAGB
Secondary Outcome Measures
the use of haemostatic staple devices
measurement (yes/no). Peroperatively, only on active bleeding a heamostatic staple device will be used. If there is no bleeding no haemostatic staple device will be used.
the use of fibrin sealant
measurement (yes/no). Peroperatively, if the staple line is not actively bleeding but is oozing, fibrin sealant is used. If there is no oozing, fibrin sealant is not used.

5. Study Description
Brief Summary
The incidence of bleeding after metabolic surgery seems to increase. The administration of a drug (tranexamic acid) that can reduce bleeding could possibly also reduce bleeding after metabolic surgery.
Objective: This study aims to determine whether administration of tranexamic acid before surgery can reduce postoperative bleeding in patients undergoing gastric bypass.
