An alternative technique for pituitary tumour removal: Sequential endoscopic-microscopic pituitary procedure (SEMPP)

We describe our novel technique, the sequential endoscopic and microscopic pituitary procedure (SEMPP) which does not require microscopically-trained neurosurgeons to alter their technique. We compare SEMPP with the PE approach in terms of outcome and safety. Retrospective chart review of consecutive SEMPP cases performed at our institution between January 2010 and December 2013 was conducted. Operative time, gross total resection rate, resolution of endocrine and visual dysfunction, hospital length of stay, cerebrospinal fluid (CSF) leak rate and revision rates were recorded. 32 patients were identified (50% female, mean age 53.0 years), and 33 SEMPP cases. Mean operating time was 132 min (range 90–200). 69% of patients experienced gross total resection. Most patients (81.3%) with preoperative visual deficit either experienced complete resolution or improved symptoms. The remainder experienced no change in vision. 12.5% (n = 4) of patients experienced intraoperative CSF leaks. All were repaired intraoperatively or with conservative management. Two patients (6.3%) experienced epistaxis managed with conservative measures. The SEMPP technique demonstrates comparable outcomes, complication rates and operative time to PE and PM techniques described in the literature.
