A biological thixotropic adhesive that contains dextrin, and at least a structural component that provides thixotropy to the adhesive, and optionally at least an antibiotic that is very useful to stimulate the process of healing of tissues in a patient, for example, to prevent anastomotic leaks of the gastrointestinal system, to affix a prosthesis in inguinal hernioplasties, in a patient and to oclude a fistula in a patient.
