Objective To explore the effect of Delta large channel endoscopic technique and unilateral biportal endoscopy(UBE)in the treatment of L5/S1 single lumbar disc herniation(sLDH)with spinal stenosis.Methods The clinical data of 60 sLDH patients combined with spinal stenosis admitted from January 2018 to August 2022 were analyzed retrospectively.The surgery of percutaneous endoscopic interlaminar discectomy(PEID)was performed with Delta large channel endoscopic technique in 32 cases(as Delta group),and spinal decompression and intervertebral discectomy was performed with UBE in 28 cases(as UBE group).Perioperative indicators,compli-cations,visual analog scale(VAS)and Oswestry disability index(ODI)were compared between the two groups,and the efficacy was evaluated by Macnab criteria at the last follow-up.Results All surgical interventions accomplished successfully in both groups.Compared with the UBE group,the intra-operative bleeding volume was less,and the operation time and hospital stays were shorter in the Delta group,with statistical difference between the two groups(P＜0.001).The VAS score and ODI was reduced in both groups after the surgery than those before the surgery,and the VAS score was lower in low back pain 3 days after the surgery and leg pain 1 month after the surgery in the Delta group than those in the UBE group(P＜0.05).All cases were followed up for six months.According to Macnab criteria,the outcomes showed that excellence in 30 cases,fair in 2 cases,and the fineness rate was 93.75％in the Delta group,and excellence in 27 cases,fair in 1 case,and the fineness was 96.43％in the UBE group,and there was no statistical difference between them(P＞0.05).Dural tear was found in one case of the Delta group,and leg pain was worse in one case of the UBE group after surgery.Conclusions Both UBE and Delta large channel endoscopic technique can achieve ideal short-term effect for sLDH with spinal stenosis.However,Delta endoscopy revealed less blood loss,mini-trauma of soft tissue,short operating time,obviously pain relief of short-term after surgery and fast recovery for patients,and the indications of UBE would be relatively wide.
