Objective To investigate the safety and effectiveness of unilateral biportal endoscopy (UBE) technique in the treatment of single-segment thoracic ossification of ligamentum flavum (TOLF). Methods Between August 2020 and December 2021, 11 patients with single-segment TOLF were treated with UBE technique. There were 6 males and 5 females, with an average of 58.2 years (range, 49-72 years). The responsible segment was T6, 7 in 1 case, T7, 8 in 1 case, T8, 9 in 2 cases, T9, 10 in 2 cases, T10, 11 in 2 cases, and T11, 12 in 3 cases. Imaging examination showed that the ossification were located on the left side in 4 cases, on the right side in 3 cases, and on bilateral sides in 4 cases. The main clinical symptoms were chest and back pain or lower limb pain, all accompanied by lower limb numbness and fatigue. The disease duration ranged from 2 to 28 months (median, 17 months). The operation time, postoperative hospital stay, and complications were recorded. Visual analogue scale (VAS) score was used to evaluate the chest and back pain and low limb pain, and Oswestry disability index (ODI) and Japanese Orthopedic Association (JOA) score were used to evaluate functional recovery before operation and at 3 days, 1 month, 3 months after operation, and last follow-up. The anteroposterior diameter of the coronal spinal canal was measured by CT before and after operation to evaluate the effect of surgical decompression. Results All operations were successfully completed. The operation time was 50-105 minutes, with an average of 80.0 minutes. No postoperative complication such as dural sac tear, cerebrospinal fluid leakage, spinal nerve injury, or infection occurred. The postoperative hospital stay was 2-5 days, with an average of 3.1 days. All incisions healed by first intention. All patients were followed up 6-22 months, with an average of 14.8 months. CT measurement at 3 days after operation showed that the anteroposterior diameter of the spinal canal was (8.63±1.61) mm, which was significantly larger than that before operation [(3.67±1.37) mm] (t=−12.181, P<0.001). The VAS score of chest and back pain and lower limb pain and ODI at each time point after operation were significantly lower than those before operation (P<0.05). The above indexes were further improved after operation, except that there was no significant difference between at 3 months after operation and at last follow-up (P>0.05), the differences between other time points were significant (P<0.05). There was no recurrence during the follow-up period. Conclusion UBE technique is a safe and effective method to treat single-segment TOLF, but its long-term effectiveness needs to be further studied.
Objective To evaluate the clinical efficacy and safety of biportal endoscopic discectomy combined with annulus fibrosus suture in the treatment of recurrent lumbar disc herniation (RLDH). Methods The clinical data of patients with RLDH who underwent biportal endoscopic discectomy combined with annulus fibrosus suture using a single-use suture device at Mianyang Orthopaedic Hospital between May 2020 and July 2022 were retrospectively collected. Visual Analogue Scale (VAS) scores for low back and leg pain and Oswestry Disability Index (ODI) scores on postoperative Day 3 and at the last follow-up were used to assess pain and functional status. Postoperative lumbar CT, MRI, and dynamic X-rays were obtained to evaluate the extent of decompression, disc removal, and spinal stability. Clinical efficacy during follow-up was assessed using the MacNab criteria since postoperative 3 months. Results Twenty-one RLDH patients (16 males, 5 females) with a mean age of (45.14±15.26) years (range: 17-62 years) were included. The involved segments were L3-L4 in 1 case, L4-L5 in 9 cases, and L5-S1 in 11 cases. All surgeries were successfully completed without complications such as nerve injury, symptomatic epidural hypertension, dural tear, cerebrospinal fluid leakage, or infection. All patients were followed up for a mean duration of (11.38±3.51) months (range: 4-17 months). No recurrence of disc herniation or segmental instability was observed during follow-up. Significant improvements were seen in VAS scores for low back pain (2.90±0.70, 1.38±0.81), leg pain (2.33±0.58, 1.29±0.46), and ODI scores [(24.12±5.05)%, (11.29±1.86)%] on postoperative Day 3 and at the last follow-up compared to the preoperative values [5.90±1.09, 6.10±0.77, (57.08±9.72)%; all P<0.05]. According to the MacNab criteria, the clinical efficacy was rated as excellent in 16 cases, good in 3 cases, and fair in 2 cases, yielding an excellent-good rate of 90.5%. Conclusion Biportal endoscopic discectomy with annulus fibrosus suture is a safe and effective treatment for RLDH, demonstrating favourable clinical outcomes and warranting further research and application.
Objective To explore the comprehensive treatment of synchronous double cancers of the esophagus and stomach. Methods The treatment procedures of 8 patients with synchronous double cancers of the esophagus andstomach admitted in the Department of Digestive Tumor Surgery of The Hospital of Traditional Chinese Medicine of Jiangsu Province between Oct. 2006 to Feb. 2013 were analyzed. Some experience of comprehensive treatment of synch-ronous double cancers of the esophagus and stomach was explored. Results Eight cases of synchronous double cancers of the esophagus and stomach were all diagnosed by endoscopic biopsy. According to the results of CT and endoscopic ultrasonography assessment， lesions which were staged earlier than T1a were cured by endoscopic mucosal resection（6 cases， including 4 cases of esophagus cancer and 2 cases of gastric cancer）， and resection operation （1 cases of esop-hagus cancer）. The lesions staged later than T2 were treated by preoperative neoadjuvant chemoradiation， surgery， and adjuvant chemoradiation after operation （8 cases， including 2 cases of esophagus cancer and 6 cases of gastric cancer）， and simple operation （1 case）. Eight patients had been followed-up for 10-76 months （averaged 41.3 months）. Six patients survived without recurrence and metastasis during the followed-up， 1 patient died in 7 months after operation， and 1 patient relapsed in 20 months after operation. Conclusions Individually designed comprehensive treatment using neo-chemotherapy， intervention chemotherapy， radio-chemotherapy， radical resction surgery， adjuvant chemotherapy， and endoscopic mucosal resection can treat synchronous double cancers of the esophagus and stomach effectively. Impr-actical pursuit for radical surgery will not result in good prognosis
Objective To study the efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP) and early endoscopic management for acute biliary pancreatitis. Methods Ninety-one patients with acute biliary pancreatitis were divided into ERCP group (46 cases) and control group (45 cases) according to the therapy methods. All patients were given positive conventional treatment, the patients of the ERCP group accepted endoscopic therapy within 48 h after hospitalization. The curative effects of two groups were observed, and the related indexes, such as time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, average time in hospital, and mortality were compared between two groups. Results Among 46 patients by ERCP diagnosis, there were 27 cases of common duct stone (CDS), 6 cases of cholecystolithiasis, 3 cases of great diverticulum at duodenal papilla side, 4 cases of suppurative cholangitis, 3 cases of stenosis in bile common duct inferior segment and 3 cases of no abnormality. Among 27 cases of CDS, 20 patients had endoscopic sphincterotomy (EST), 4 had duodenal papilla artifistulation, 20 had calculus removed by once basket and aerocyst, and 7 patients with suppurative cholangitis and great stone saccepted EST or macadam after stabilization. The cases of great diverticulum at duodenal papilla side and cases of stenosis in bile common duct inferior segment accepted EST, the cases of suppurative cholangitis accepted endoscopic nasobiliary drainage (ENBD), and all accepted ENBD. The time of abdominal pain relief, temperature to normal, leukocytes to normal, liver function to normal, and the average time in hospital in the ERCP group were significantly shorter than those in the control group (Plt;0.05). The blood amylase to normal time and mortality had no significant differences between two groups (Pgt;0.05). Conclusion The early endoscopic management for patients with acute biliary pancreatitis can clear etiology, reduce the time in hospital and be minimally invasive, safe, and effective.
