Objective To investigate the perioperative management and the results of surgical treatment of spinal tuberculosis associated with diabetes mellitus. Methods The cl inical data were analysed retrospectively from 42 patients with spinal tuberculosis associated with type 2 diabetes mell itus who were surgically treated between July 2001 and January 2009.There were 22 males and 20 females with an average age of 56.5 years (range, 41-78 years). The disease duration was 4-18 months (mean, 7.5 months). The involved vertebrae included 2 cervical vertebrae, 13 thoracic vertebrae, 17 thoracolumbar vertebrae, and 10 lumbar vertebrae. Of them, 18 patients compl icated by paraplegia, and 25 patients had more than one of concomitant diseases. Anterior debridement and bony grafting with anterior instrumentation fixation were performed in 16 patients; anterior debridement and bony grafting with posterior instrumentation fixation in 4 patients; posterolateral costotransversectomy debridement and interbody fusion with posterior instrumentation fixation in 8 patients; posterior debridement and bony grafting with posterior fixation in 7 patients; sinus resectomy and focus debridement in 2 patients; anterior debridement and bony grafting in 3 patients; and CT guided percutaneous catheter drainage in 2 patients. Postoperative anti-tuberculosis treatment was given for 12-24 months. Results The patients were followed up 1.5-5.0 years, with a mean period of 3.5 years. One patient died of pulmonary infection after 1 week of operation; 1 patient died of myocardial infarction after 2 years of operation; and other patients survived without tuberculosis recurrence. Among 38 patients who received bony grafting, 34 patients achieved bony fusion, 3 suffered bony grafting failure without kyphotic deformity or instabil ity except 1 patient who died from pulmonary infection. Among 18 cases compl icated by paraplegia, nerve function improved to a certain extent. The intraoperative and postoperativecompl ications occured in 28 cases. The systemic compl ications mainly included heart insufficiency in 5, heart rrhythmia in 3, pulmonary infection in 2, urinary tract infection in 2, and stree ulcer in 1; they were cured after medical treatment. The local complications mainly included sinus tract formation in 5, pleural tear in 2, neurologic injury in 2, intraoperative tear of inferior vena cava in 2, and the loosening of transpedicular screws in 4; they all were cured effectively. Conclusion Surgical treatment of spinal tuberculosis associated with diabetes mell itus appears to be a beneficial procedure on the condition that the blood glucose is controlled and the associated disorders and postoperative complications are properly handled, and reasonably selection of surgical procedures is very important. Instrumentation fixation provides adequate stabil ity to allow early mobilization.

ObjectiveTo explore the effect of perioperative nutritional management on patients with spinal cord injury under the enhanced recovery after surgery (ERAS) theory.MethodsA total of 82 patients with spinal cord injury admitted to a tertiay hospital in Shanghai between August 2018 and May 2020 were selected by convenience sampling method. They were randomly divided into intervention group and control group, with 41 cases in each group. The patients in the control group received conventional orthopaedics elective surgery nutritional management, while the patients in the intervention group adopted perioperative nutritional management based on ERAS concept, including establishing a multidisciplinary nutritional management team, conducting admission and regular nutritional screenings, and then developing targeted nutritional interventions based on the screening results. Biochemical indexes of nutritional assessment, electrolyte indexes, nutrition-related complications and general inpatient indexes were observed and compared between the two groups.ResultsThere were statistically significant differences in albumin, prealbumin, total protein, hemoglobin, potassium, sodium, and chlorine between the two groups on the first day after surgery and one day before discharge (P<0.05). The incidences of hypoglycemia (2.4% vs. 19.5%) and total complications (19.5% vs. 61.0%) in the intervention group were lower than those in the control group, and the differences were statistically significant (P<0.05). The total hospital stay [(10.48±2.61) vs. (12.09±2.74) d], postoperative hospital stay [(5.57±2.35) vs. (7.55±3.01) d], and hospital expenses [(11.21±4.42)×104 vs. (14.73±5.51)×104 yuan] in the intervention group were less than those in the control group (P<0.01).ConclusionPerioperative nutritional management under the ERAS theory can effectively improve the nutritional status of patients with spinal cord injury, maintain electrolyte balance, reduce the incidence of complications, shorten the length of hospitalization, reduce the cost of hospitalization, and promote postoperative rehabilitation of patients.
ObjectiveTo explore the technique of hepatic artery reconstruction in complicated hilar cholangiocarcinoma surgery. MethodThe clinicopathologic data of 3 patients with complicated hilar cholangiocarcinoma with arterial invasion underwent hepatic artery reconstruction in the Department of Hepatopancreatobiliary Center of Beijing Tsinghua Changgung Hospital from March to July 2022 were retrospectively analyzed. ResultsAll 3 patients (case 1–3) were the males, aged 53, 68, and 56 years, respectively, and with hypertension or diabetes; the longitudinal diameters of the tumor were 3.5 cm, 3.0 cm, and 3.2 cm, respectively. All patients had the right hepatic artery invasion. Case 2 and 3 had the arterial stratification. The arterial defects after radical resection were 4.5 cm, 3 cm, and 3 cm, respectively. The right or right posterior hepatic artery was reconstructed by the autotransplantation of right gastroomental artery, the left hepatic artery, and the anterior superior pancreaticoduodenal artery, respectively. After operation, the reconstructed hepatic arteries were unobstructed and free of stenosis, and there were no complications such as bleeding, infection, and thrombosis by Doppler ultrasound and CT angiography. The results of postoperative pathological diagnosis were the hilar cholangiocarcinoma with arterial invasion, and all the incisal edges were negative. ConclusionFrom the preliminary results of 3 cases, it is safe, feasible, and effective to select proper autologous artery (matched in length and caliber) for reconstruction the defective invaded hepatic artery which resected together with hilar cholangiocarcinoma, but the technical difficulty is still relatively high.
Objective To observe the effects of extracorporeal shock wave therapy (ESWT) combined with kinesio taping (KT) on chronic non-specific low back pain (CNLBP). Methods CNLBP patients who visited the Department of Rehabilitation Medicine, the Second Affiliated Hospital of Nantong University between January 2021 and January 2022 were selected. The included patients were divided into ESWT group, KT group, and combined treatment group using a random number table method. All patients received conventional rehabilitation. The ESWT group was treated with ESWT, the KT group was given KT therapy, and the combined treatment group were treated with ESWT and KT with the same treatment frequency as before. Visual Analogue Scale (VAS), Oswestry Disability Index (ODI), MOS 36-item Short form Health Survey (SF-36) and Self-rating Anxiety Scale (SAS) were used to evaluate pain severity, lumbar spine function, quality of life, and anxiety status in all groups before and 4 weeks after treatment, respectively. Results A total of 85 patients were included. Among them, there were 29 cases in the ESWT group, 28 cases in the KT group, and 28 cases in the combined treatment group. There was no adverse event in any group. The intra-group comparison results showed that the VAS, ODI, and SAS scores of the three groups after 4 weeks of treatment were lower than those before treatment (P<0.05), while the SF-36 scores in all dimensions were higher than those before treatment (P<0.05). Before treatment, there was no statistically significant difference in VAS, ODI, SAS, or SF-36 scores among the three groups (P>0.05). After 4 weeks of treatment, there were statistically significant differences in VAS, ODI, SAS, and SF-36 scores among the three groups (P<0.05). The results of multiple comparisons between groups showed that the VAS scores of the ESWT group and the combination therapy group were lower than those of the KT group (P<0.05); the ODI scores of the combination therapy group were lower than those of the ESWT group and the KT group (P<0.05); the SAS scores of the combination therapy group were lower than those of the KT group (P<0.05); the SF-36 scores of each dimension were compared in pairs among the three groups, and the differences were statistically significant (P<0.05); there was no statistically significant difference in pairwise comparison of other indicators between groups (P>0.05). Conclusion ESWT combined with KT can more effectively improve the pain and lumbar spine function of patients with CNLBP, and improve the quality of life of patients.
Objective To investigate the effectiveness of Quadrant retractor for the treatment of recurrent lumbar disc protrusion. Methods Between July 2008 and March 2010, 18 cases of recurrent lumbar disc protrusion were treated with Quadrant. There were 13 males and 5 females with an average age of 43 years (range, 35-67 years). Involved segments includedL4, 5 in 6 cases and L5, S1 in 12 cases. The time between first operation and recurrence was 12-120 months (mean, 42.8 months). Before operation, radiological evaluation including X-ray, CT, and MRI were performed. Visual analogue scale (VAS) score and modified MacNab criteria were used to evaluate the effectiveness. Results The operation time was 40-80 minutes (mean, 60 minutes), and the amount of blood loss was 80-120 mL (mean, 100 mL). All operations were performed successfully, and no compl ication of infection and nerve injury occurred. Incisions healed by first intention. Cerebrospinal fluid leakage occurred in 2 cases and was cured at 3 days after operation by removal of drainage. Eighteen patients were followed up 12-30 months (mean, 22 months). The VAS score of leg pain was decreased from 7.3 ± 2.2 preoperatively to 2.0 ± 1.3 at the final follow-up, showing significant difference (t=11.08, P=0.00). According to modified MacNab criteria, the results were excellent in 12 patients and good in 6 patients. No recurrence was found during follow-up. Conclusion Discectomy via Quadrant retractor is a safe and effective minimally invasive surgical technique in treating recurrent lumbar disc protrusion.
Objective To evaluate the effect of posterior lumbar interbody fusion (PLIF) using single incision via MAST Quadrant retractor in the management of lumbar spondylolisthesis. Methods From July 2008 to June 2009, 20 cases of lumbar spondylolisthesis were treated with posterior lumbar interbody fusion via MAST Quadrant retractor using single incision,including 2 cases of degenerative spondylolisthesis and 18 cases of isthmic spondylolisthesis. There were 8 males and 12 females aged from 34 to 62 years (average 45.5 years). The disease course was 1 to 6 years (mean 34.5 months). The spondylol isthesis locations were L4,5 in 8 cases and L5, S1 in 12 cases. According to Meyerding classification, all cases were classified as degree I. The Visual Analogue Scale (VAS) score was (6.6 ± 1.2) points. The operative time, the blood loss, and the therapeutic effects were recorded. Results The operative time was (155 ± 23) minutes and the amount of blood loss was (360 ± 102) mL. The hospitalization time were (12.0 ± 3.4) days. All incisions healed by first intention. X-ray films showed spondylolisthesis reduction immediately after operation. All patients were followed up 14.3 months on average (from 9 to 20 months). The VAS score decreased to (1.6 ± 2.3) points at the last follow-up, showing significant difference when compared with that of preoperation (P lt; 0.05). The X-ray films showed that lumbar interbody fusion was achieved in all the patients. No lossening, breakage, and displacement of pedicle screw fixation was observed. According to Nakai standard, the results were excellent in 18 cases and good in 2 cases at the last follow-up. Conclusion As long as the indication is strictly chosen, PLIF via MAST Quadrant retractor is a safe, effective, and minimally invasive surgical technique in treating lumbar spondylolisthesis.
ObjectiveTo observe the effects of upper limb rehabilitation robot-assisted training combined with mirror therapy on unilateral spatial neglect (USN) in stroke patients.MethodsA total of 40 patients with USN admitted to the Department of Rehabilitation Medicine of the Second Affiliated Hospital of Nantong University from January 2017 to December 2018 were selected and randomly divided into the trial group and the control group, with 20 cases in each group. The trial group used upper limb rehabilitation robot-assisted training combined with mirror therapy and USN comprehensive rehabilitation treatment. The control group patients only received USN comprehensive rehabilitation treatment. All patients continued treatment for 4 weeks. Before treatment and after 4 weeks of treatment, the modified Barthel index (MBI) was used to assess the activities of daily living, the Fugl-Meyer assessment (FMA) was used to assess motor function, and the Catherine-Bergego scale was used to assess the degree of USN.ResultsThere was no statistically significant difference in general information between the two groups of patients (P>0.05). There was no significant difference in MBI, FMA or USN degree scores between the two groups before treatment (P>0.05). After 4 weeks of treatment, the MBI, FMA and USN degree scores of the two groups were improved compared with those before treatment (P<0.05). The improvements in MBI, FMA and USN degree scores of the trial group were 14.75±1.97, 17.05±3.93 and 5.25±2.29, respectively, and those of the control group were 9.75±4.44, 8.30±2.06 and 3.10±0.72, respectively, and the differences were statistically significant (P<0.05).ConclusionsUpper limb rehabilitation robot-assisted training combined with mirror therapy can effectively improve the spatial neglect of USN patients, and improve the ability of daily living and motor functions.
