OBJECTIVE: Cerebrospinal fluid leakage is the most common complication of endoscopic trans-sphenoidal pituitary surgery. However, there is no uniformly accepted way of managing this complication when it occurs intra-operatively. This paper describes a quick, simple technique, involving layered fibrin glue and gelatin sponge, which does not compromise post-operative patient follow up. METHOD: Retrospective review of all endoscopic pituitary surgery cases conducted at a single institution since the introduction of this technique in 2002. RESULTS: A total of 120 endoscopic pituitary operations were performed (96 primary procedures and 24 revisions). All intra-operative cerebrospinal fluid leaks were managed using the described method, with a failure rate of 3.6 per cent. The overall post-operative leakage rate was 1.7 per cent. CONCLUSION: This simple, conservative technique avoids the need for further dissection and the use of non-absorbable foreign material, and has a low incidence of post-operative cerebrospinal fluid leakage.
