OBJECTIVE: To compare the clinical outcomes of hydraulic perfusion pump and traditional water fhushing in percutaneous endoscopic lumbar discectomy.
METHODS: From January 2016 to December 2018, 72 patients with lumbar disc herniation failed to conservative treatment were enrolled in this study. The patients were divided into hydraulic perfusion pump group and traditional water flushing group, 36 cases in each group. There were no significant differences in gender, age, prominent segment, clinical classification, preoperative visual analogue scale (VAS) and Japanese Orthopaedic Association(JOA) score between two groups (P>0.05). All operations were performed by the same surgeon, and the operations were completed by hydraulic perfusion pumpflushing or traditional water flushing assisted surgery. The operation time, intraoperative blood loss, hospital stay were recorded;VAS and JOA scores were observed before and after operation;the incidences of postoperative complications were compared between two groups.
RESULTS: All the patients were followed up for 12 to 24 (15.7±5.1) months. Compared with the traditional water flushing group, the operation time of the hydraulic perfusion pump group was shorter [(65.5±21.3) min vs (74.8±19.9) min, t=9.465, P=0.003], and intraoperative blood loss was less [(21.2±12.9)ml vs (27.4± 14.1) ml, t=8.331, P=0.012], there was no statistical difference in hospital stay between two groups. Postoperative VAS scores at 1 day, 2 weeks and the final follow-up and postoperative JOA scores at the final follow-up of the two groups of patients improved compared with those before operation, but there was no significant difference between two groups (P>0.05). In the traditional water flushing group, the intracranial hypertensionoccurred during operation and the operation time was forced to shorten in 5 cases, the nerve root adventitia injury in 4 cases, and the postoperative recurrence in 4 cases. No intracranial hypertension during operation was found in the hydraulic perfusion pump group, nerve root adventitia injury occurred in 1 case, postoperative recurrence in 2 cases. The incidence of complication of the hydraulic perfusion pump group was lower than that ofthe traditional water flushing group.
CONCLUSION: Both hydraulic perfusion pump and traditional water flushing assisted percutaneous endoscopic lumbar disc herniation can achieve satisfactory clinical results, but the former has shorter operation time, clearer intraoperative vision, less bleeding, and fewer intraoperative and postoperative complications.
