Multifunctional curve and detachable suction and stripping tubes with electrical coagulation in neuroendoscope assisted pituitary tumor resection through endonasal transsphenoidal pathway

Abstract

Objective To develop multi-functional suction tubes used in neuroendoscope assisted pituitary tumor surgery via endonasal transsphenoidal pathway and investigate their application value. Methods The experiments included 145 pituitary tumor patients, recruited in our hospital from March 2014 to March 2015. Self-regulating multi-functional curve and detachable suction tubes were used in neuroendoscope assisted pituitary tumor resection, which could do suction, electrical coagulation and stripping together. The efficacy of them was analyzed. Results There were 101 total tumor resection, 26 subtotal resection and 18 partial resection in the 145 pituitary tumor patients. The average operative blood loss was 41.52 mL with application of the multifunctional suction tubes. The shortest time in operation was 28 min, and the average operation time was 76.55 min. Patients were discharged 3-5 days after surgery and the prognosis were good. Conclusion As a safe and effective novel endoscopic neurosurgery instrument, the multifunctional curve and detachable suction and stripping tubes with electrical coagulation could significantly improve surgery effectiveness and reduce operative blood loss when used in pituitary tumor resection through endonasal transsphenoidal pathway.
