Objective To compare the effectiveness between unilateral biportal endoscopic lumbar interbody fusion (ULIF) and endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) in treatment of lumbar spinal stenosis combined with intervertebral disc herniation. Methods A clinical data of 64 patients with lumbar spinal stenosis and intervertebral disc herniation, who were admitted between April 2020 and November 2021 and met the selection criteria, was retrospectively analyzed. Among them, 30 patients were treated with ULIF (ULIF group) and 34 patients with Endo-TLIF (Endo-TLIF group). There was no significant difference in baseline data such as gender, age, disease duration, lesion segment, preoperative visual analogue scale (VAS) score of low back pain and leg pain, Oswestry disability index (ODI), spinal canal area, and intervertebral space height between the two groups (P>0.05). The operation time, intraoperative blood loss, hospital stays, and postoperative complications were compared between the two groups, as well as the VAS scores of low back pain and leg pain, ODI, and imaging measurement indicators (spinal canal area, intervertebral bone graft area, intervertebral space height, and degree of intervertebral fusion according to modified Brantigan score). Results Compared with the Endo-TLIF group, the ULIF group had shorter operation time, but had more intraoperative blood loss and longer hospital stays, with significant differences (P<0.05). The cerebrospinal fluid leakage occurred in 2 cases of Endo-TLIF group and 1 case of ULIF group, and no other complication occurred. There was no significant difference in the incidence of complications between the two groups (P>0.05). All patients in the two groups were followed up 12 months. The VAS scores of lower back pain and leg pain and ODI in the two groups significantly improved when compared with those before operation (P<0.05), and there was no significant difference between different time points after operation (P>0.05). And there was no significant difference between the two groups at each time point after operation (P>0.05). Imaging examination showed that there was no significant difference between the two groups in the change of spinal canal area, the change of intervertebral space height, and intervertebral fusion rate at 6 and 12 months (P>0.05). The intervertebral bone graft area in the ULIF group was significantly larger than that in the Endo-TLIF group (P<0.05). ConclusionFor the patients with lumbar spinal stenosis combined with intervertebral disc herniation, ULIF not only achieves similar effectiveness as Endo-TLIF, but also has advantages such as higher decompression efficiency, flexible surgical instrument operation, more thorough intraoperative intervertebral space management, and shorter operation time.
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.
The traditional view is that breast reconstruction is not an option for day surgery center. As a result, few hospitals in the world conduct this operation in day surgery center. Endoscopic breast reconstruction with liposuction and robot-assisted breast reconstruction are minimally invasive surgeries for breast cancer patients, but they cannot be carried out in the day surgery center due to long operation time. The novel endoscopic-assisted immediate implant-based breast reconstruction after nipple sparing mastectomy through a single axillary incision for breast cancer patients has been successfully conducted in the day surgery center in our hospital due to short operation time and small trauma. Standardized management of the complete process from the patient selection to follow-up after discharge brings rapid recovery and few complications. At the same time, the development of endoscopic surgery makes the breast almost scarless and improves aesthetic results. Therefore, the mode of endoscopic-assisted reconstruction in the day surgery center of our hospital is expected to be popularized in the whole country.
ObjectiveTo study the application value of multi-slice CT portography (MSCTP) in the diagnosis and evaluation of esophageal and gastric varices (EGV) caused by cirrhosis. MethodsPatients with cirrhosis diagnosed between September 2009 and December 2012 were screened in this study. And the consistency of MSCTP and digestive endoscopy in the diagnosis, classification and grading of EGV in cirrhosis were evaluated. ResultsA total of 78 patients were included in this study, and there were 55 patients with EGV diagnosed by endoscopy, including 35, 16 and 4 patients with GOV1, GOV2 and IGV1 respectively by Satin type standards; and the number of patients with mild, moderate and severe EGV by general grading standards was 2, 15, and 37, respectively. In this cohort, the findings of MSCTP examination also showed that 58 patients had EGV, including 36, 17, 4 and 1 patients with GOV1, GOV2, IGV1 and IGV2 by Satin type standards; and the number of patients with grade I,Ⅱ andⅢ EGV by Kim grading standards was 5, 16 and 37, respectively. Statistical analysis showed that there was a high consistency between endoscopy and MSCTP in the diagnosis (Kappa=0.712, P=0.000), typing (Kappa=0.732, P=0.000) or grading (Kappa=0.863, P=0.000) of EGV. ConclusionMSCTP has a high application value in the diagnosis and severity evaluation of EGV in patients with cirrhosis.

Objective To analyze the perioperative efficacy of enhanced recovery after surgery (ERAS) in the treatment of lumbar disc herniation using unilateral biportal endoscopy technique. Methods A total of 55 patients who received unilateral biportal endoscopy technique for the treatment of lumbar disc herniation in Tianjin Hospital between January and December 2020 were selected and randomly divided into the traditional group and the ERAS group according to random number table method. The routine inpatient care management was adopted in the traditional group, while the holistic integrated care plan was formulated in the ERAS group according to the multidisciplinary collaboration of the accelerated rehabilitation plan. The first postoperative exhaust time, the first time out of bed, length of hospital stay, hospital costs, Visual Analogue Scale (VAS) scores before operation, one day and three days after operation, Oswestry Disability Index (ODI) scores before operation and one month after operation, and the excellent and good rate of modified MacNab efficacy one month after operation were compared between the two groups. Results There were 28 cases in the traditional group and 27 cases in the ERAS group. The first postoperative exhaust time [(2.31±1.02) vs. (3.19±0.87) h], the first postoperative ambulation time [(1.06±0.40) vs. (2.00±0.53) d], length of hospital stay [(3.8±0.8) vs. (4.6±0.8) d], and hospital cost [(32.18±9.10) thousand yuan vs. (39.81±11.10) thousand yuan] in the ERAS group were all less than those in the traditional group, and the differences were statistically significant (P<0.05). The VAS scores of the ERAS group one day after operation (3.2±0.8 vs. 4.1±0.8) and three days after operation (1.4±0.5 vs. 1.7±0.5) were lower than those of the traditional group (P<0.05). The ODI scores of the ERAS group one month after operation was lower than that of the traditional group (13.3±4.0 vs. 16.6±4.8, P<0.05). In the modified MacNab efficacy evaluation one month after surgery, there was no significant difference in the excellent and good rate between the ERAS group and the traditional group (96.3% vs. 96.4%, P>0.05). Conclusions ERAS regimen can significantly accelerate the patients’ recovery, including shortening the first exhaust time, facilitating early ambulation, and reducing the hospital stay and hospitalization expenses. Meanwhile, ERAS regimen can effectively reduce the postoperative pain of the patients, and promote early functional recovery.
Objective To compare the effectiveness of unilateral biportal endoscopic transforaminal lumbar interbody fusion (UBE-TLIF) and endoscopic transforaminal lumbar interbody fusion (Endo-TLIF) in the treatment of single-segment degenerative lumbar spinal stenosis with lumbar spondylolisthesis. Methods Between November 2019 and May 2023, a total of 81 patients with single-segment degenerative lumbar spinal stenosis with lumbar spondylolisthesis who met the selection criteria were enrolled. They were randomly divided into UBE-TLIF group (39 cases) and Endo-TLIF group (42 cases). There was no significant difference in baseline data between the two groups (P>0.05), including gender, age, body mass index, surgical segment, and preoperative visual analogue scale (VAS) scores for low back and leg pain, Oswestry Disability Index (ODI), and serum markers including creatine kinase (CK) and C reactive protein (CRP). Total blood loss (TBL), intraoperative blood loss, hidden blood loss (HBL), postoperative drainage volume, and operation time were recorded and compared between the two groups. Serum markers (CK, CRP) levels were compared between the two groups at 1 day before operation and 1, 3, and 5 days after operation. Furthermore, the VAS scores for low back and leg pain, and ODI at 1 day before operation and 1 day, 3 months, 6 months, and 12 months after operation, and intervertebral fusion rate at 12 months after operation were compared between the two groups. Results All surgeries were completed successfully without occurrence of incision infection, vascular or nerve injury, epidural hematoma, dural tear, or postoperative paraplegia. The operation time in UBE-TLIF group was significantly shorter than that in Endo-TLIF group, but the intraoperative blood loss, TBL, and HBL in UBE-TLIF group were significantly more than those in Endo-TLIF group (P<0.05). There was no significant difference in postoperative drainage volume between the two groups (P>0.05). The levels of CK at 1 day and 3 days after operation and CRP at 1, 3, and 5 days after operation in UBE-TLIF group were slightly higher than those in the Endo-TLIF group (P<0.05), while there was no significant difference in the levels of CK and CPR between the two groups at other time points (P>0.05). All patients were followed up 12 months. VAS score of low back and leg pain and ODI at each time point after operation significantly improved when compared with those before operation in the two groups (P<0.05); there was no significant difference in VAS score of low back and leg pain and ODI between the two groups at each time point after operation (P>0.05). There was no significant difference in the intervertebral fusion rate between the two groups at 12 months after operation (P>0.05). ConclusionUBE-TLIF and Endo-TLIF are both effective methods for treating degenerative lumbar spinal stenosis with lumbar spondylolisthesis. However, compared to Endo-TLIF, UBE-TLIF requires further improvement in minimally invasive techniques to reduce tissue trauma and blood loss.
ObjectiveTo evaluate early effectiveness of posterior 180-degree decompression via unilateral biportal endoscopy (UBE) in the treatment of lumbar spinal stenosis (LSS) combined with Michigan State University (MSU)-1 lumbar disc herniation (LDH). MethodsA retrospective analysis was conducted on clinical data from 33 patients with LSS combined with MSU-1 LDH, who met selection criteria and were treated between March 2022 and January 2024. All patients underwent UBE-assisted 180-degree spinal canal decompression. The cohort comprised 17 males and 16 females, aged 37-82 years (mean, 67.1 years). Preoperative presentations included bilateral lower limbs intermittent claudication and radiating pain, with disease duration ranging from 5 to 13 months (mean, 8.5 months). Affected segments included L3, 4 in 4 cases, L4, 5 in 28 cases, and L5, S1 in 1 case. LSS was rated as Schizas grade A in 4 cases, grade B in 5 cases, grade C in 13 cases, and grade D in 11 cases. LDH was categorized as MSU-1A in 24 cases, MSU-1B in 2 cases, and MSU-1AB in 7 cases. Intraoperative parameters (operation time, blood loss) and postoperative hospitalization length were recorded. The visual analogue scale (VAS) score and Oswestry Disability Index (ODI) were used to assess the lower limb pain and functional outcomes after operation. Clinical efficacy was evaluated at last follow-up via modified MacNab criteria. Quantitative radiological assessments included dural sac cross-sectional area (DSCA) measurements and spinal stenosis grading on lumbar MRI. Morphological classification of lumbar canal stenosis was determined according to the Schizas grading, categorized into four grades. Results The operation time was 60.4-90.8 minutes (mean, 80.3 minutes) and intraoperative blood loss was 13-47 mL (mean, 29.9 mL). The postoperative hospitalization length was 3-5 days (mean, 3.8 days). All patients were followed up 12-16 months (mean, 13.8 months). The VAS score and ODI improved at immediate and 3, 6, and 12 months after operation compared to before operation, and the differences between different time points were significant (P<0.05). At last follow-up, the clinical efficacy assessed by the modified MacNab criteria were graded as excellent in 23 cases, good in 9 cases, and poor in 1 case, with an excellent and good rate of 96.97%. Postoperative lumbar MRI revealed the significant decompression of the dural sac in 32 cases, with 1 case showing inadequate dural expansion. DSCA measurements confirmed progressive enlargement and stenosis reduction over time. The differences were significant (P<0.05) before operation, immediately after operation, and at 6 months after operation. At 6 months after operation, Schizas grading of spinal stenosis improved to grade A in 27 cases and grade B in 6 cases. ConclusionPosterior 180-degree decompression via UBE is a safe and feasible strategy for treating LSS combined with MSU-1 LDH, achieving effective neural decompression while preserving intervertebral disc integrity.
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 determine the independent influencing factors of intraoperative choking during painless gastrointestinal endoscopy (PGIE) after coronavirus disease 2019 (COVID-19). Methods The data of patients undergoing PGIE with COVID-19 in Northern Jiangsu People’s Hospital between December 2022 and April 2023 were retrospectively collected. Multiple logistic regression analysis was used to screen the influencing factors of intraoperative coughing events that occurred during the diagnosis and treatment process. Results A total of 948 patients were included, with 93 (9.8%) cases of choking. The results of the multiple logistic regression analysis showed that smoking and unresolved cough were independent risk factors for coughing (P<0.05), while colonoscopy and infection duration beyond 14 days between diagnosis and treatment were independent protective factors for coughing (P<0.05). ConclusionsWhen patients with COVID-19 undergoing PGIE, special attention should be paid to high-risk groups such as smoking and unresolved cough. It is necessary to strengthen intraoperative monitoring and implementation of prevention and control measures to reduce the incidence of coughing and improve the safety of diagnosis and treatment for patients.
