Modified hemostatic technique using microfibrillar collagen hemostat in endoscopic endonasal transsphenoidal surgery: technical note.

Microfibrillar collagen hemostat (MCH) is accepted as an effective topical hemostatic agent during endoscopic endonasal transsphenoidal surgery (EETS), particularly to achieve venous hemostasis; however, handling MCH may be troublesome because of its adherence to gloves and instruments. We describe here a method of "injection" of MCH suspension using a syringe applicator. This technique allows a rapid and precise delivery of MCH to the bleeding points and thereby results in effective hemostasis; in addition, it is easy to prepare and it is also inexpensive.
