Advantage of the treatment technology of TESSY transforaminal endoscopic discectomy on lumbar disc herniation / 中国综合临床

ABSTRACT

Objective To compare the clinical application of endoscope system and dimensional disc hole mirror, and its advantages of percutaneous transforaminal endoscopic discectomy TESSY technology. Methods Two hundred and eighty patients with lumbar disc herniation randomly divided into foraminal mirror group and endoscopic group(140 cases for each groups). Patients in foraminal mirror group were given TESSY removal of nucleus pulposus through lateral approach road,while in endoscopic group were given posterior approach discectomy. The operation time,bleeding volume,postoperative time,incision length,waist and leg waist pain and functional recovery were recorded. Results The operation incision length in foraminal mirror group was(0. 8 ± 0. 1)mm,significantly shorter in the endoscopic group((1. 7 ± 0. 2)mm),the amount of bleeding in foraminal mirror group was( 9. 8 ± 4. 3 )ml,significantly less than the endoscopic group(( 78. 6 ± 18. 8)ml). The above data were statistically significant difference( t =21. 753,19. 280;P ﹤0. 01 ). The getting out of bed time after operation was(0. 3 ± 0. 1)d,significantly earlier than that in the endoscopic group ((3. 5 ± 0. 8)d;t=21. 451;P﹤0. 01). VAS scores of patients in two group at postoperative were(7. 4 ± 1. 8) and(7. 3 ± 1. 6),significantly decreased than that of preoperative((2. 7 ± 1. 7)and(2. 5 ± 1. 6);t=10. 259, 11. 465;P﹤0. 01),But there were no significant differences between the two groups before and after treatment ( P﹥ 0. 05 ). After treatment,waist function recovery in the two groups were 97. 1%( 136/140 ),95. 7%(134/140),and the difference was significant(χ2 =0. 415,P﹥0. 05). Conclusion Foraminal mirror TESSY technique in the treatment of lumbar disc herniation with microendoscopy discectomy with small incision is proved a good approach with less bleeding,postoperative early rehabilitation.
