Abstract:
Background Postoperative indwelling drainage is beneficial to alleviate local hematoma, reduce incision tension, relieve postoperative pain, and speed up recovery, however, it also increases the risk of wound infection. There is no literature report on whether drainage should be placed after percutaneous endoscopic lumbar discectomy.
Objective To compare the clinical effect of indwelling drainage after percutaneous endoscopic lumbar discectomy, and provide data support for the improvement of surgical procedures and the formulation of postoperative rehabilitation programs.
Methods A retrospective analysis was performed on 140 patients who underwent spinal endoscopic surgery in the department of orthopaedics of our hospital from November 2018 to December 2020. The patients were divided into two groups according the drainage. The differences in postoperative infection rate, postoperative hematoma formation rate, preoperative and postoperative visual analogue scale (VAS) were observed and statistically analyzed.
Results There were 70 cases in with postoperative drainage group, with 54 males and 16 females, average age of (46.83 ± 16.31) years, and 70 cases were in without postoperative drainage group, with 45 males and 25 females, average age of (47.60 ± 17.46) years. All patients were followed up for 3 months. The postoperative VAS score of the drainage group was significantly lower than that of the non-drainage group (P<0.05), however, there were no significant differences in the VAS score of preoperative, 15d after operation and 3 months after operation (all P>0.05). During the postoperative follow-up, there was 1 case of postoperative hematoma in the non-drainage group, no hematoma formation was found in the drainage group, and no postoperative infection occurred in the two groups.
Conclusion The indwelling drainage after percutaneous endoscopic lumbar discectomy is helpful in reducing the formation of postoperative hematoma and alleviating postoperative pain.
