OBSIDIAN en una anastomosis esofagogástrica circular grapada después de una esofagectomía de Ivor Lewis (Obsidian ph II)
Evaluación de la eficacia y la seguridad de BioMatrix OBSiDiAN autólogo para mejorar una anastomosis esofagogástrica circular con grapas después de la esofagectomía de Ivor Lewis en un ensayo controlado aleatorio multicéntrico.
Oesophagectomy is very invasive surgery. A leakage at the level of the connection between oesophagus and stomach made during surgery causes a lot more problems and can lead to death. Studies show that the leakage rate sometimes goes up to 40 per cent. The chance of dying if you develop a leak after surgery is 15%, while the overall chance of dying during hospitalisation for this procedure is about 4%. We want to investigate whether the use of this new type of 'glue' (Obsidian®) can reduce the number of leaks. We invite you to participate in a clinical trial with the aim of investigating whether Obsidian® is safe and can reduce the number of leaks after oesophageal surgery in patients with oesophageal cancer. We want to apply a new type of 'glue', Obsidian®, at the level of the new connection between oesophagus and stomach.

Descripción detallada
STUDY PRODUCT Autologous BioMatrix: Obsidian (medical device class III)
STUDY POPULATION Subjects ≥ 18 years and ≤ 75 years of age scheduled for elective Ivor Lewis esophagectomy for esophageal cancer with a circular stapled intrathoracic esophagogastric anastomosis.
SAMPLE SIZE A total of 90 patients will be included in the study. ENROLEMENT PERIOD Based on an annual number of 70-80 esophagectomies in University Hospital Ghent, we predict an enrolment period of 3 years.
STUDY DURATON Considering a 3 years enrolment period and a 1 year follow up we predict a study duration of 4 years.
PRIMAIRY ANALYSIS
• Anastomotic leak within 30 days post operatively. Anastomotic leak type I, II and III is defined according to the Esophagectomy Complications Consensus Group (ECCG).

Experimental: study group
For the study group, a unit of autologous BioMatrix OBSiDiAN will be produced. Blood sample (120ml) will be taken after randomization at the ending of the abdominal phase of the surgery. The surgeon will create an esophagogastric anastomosis, after ruling out tension or torsion. Around 1-2ml of autologous BioMatrix OBSiDiAN will be applied on the distal/or proximal resection stump before the stapled anastomose will be created. After firing the standard circular device and creation of a functional anastomosis, a further 2.5-3ml OBSiDiAN must be applied circumferentially on the outside on the anastomosis. Once application is completed, a 30 seconds waiting period is required before putting the esophagus back into the surgical field (study specific). A methylene blue leakage test or other leakage test is performed (standard of care). If there is a leak, the anastomosis will be corrected or the completed procedure has to be done again. |
To create OBSiDiAN BioMatrix, 120 ml of the the patient's blood is added to the processing unit. The Vivostat® processor unit heats, separates, centrifugates to get the plasma. Batroxobin is added. After again processing, the result is an OBSiDian syringe filled with BioMatrix Obsidian®ASG. This will be applied on the anastomosis |
