BACKGROUND:There are stil about 10%-30%of patients presenting no obvious improvement of symptoms after lumbar disc herniation surgery, which are col ectively known as the lumbar spine post-surgery failure syndrome, and lumbar instability is one of the important reasons. OBJECTIVE:To evaluate the feasibility and efficacy of surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation on lumbar intervertebral disc protrusion concurring lumbar instability via MAST Quadrant retractor. METHODS:From December 2011 to October 2012, 62 cases of lumbar intervertebral disc protrusion concurring lumbar instability were treated with posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor. There were 38 female and 24 male ranging in age from 37 to 69 years (average 53.7 years). After operation, al patients were fol owed-up to evaluate the effect of the treatment. RESULTS AND CONCLUSION:The operative time was 90-210 minutes, average 145 minutes, and the amount of blood loss was 50-300 mL, average 120 mL. The hospitalization time was 5-9 days, average 6 days. Al incisions healed by first intention. Al patients were fol owed up 7.2 months on average (from 3 to 10 months). The preoperative JOA score was (10.25±2.34) points. The postoperative JOA score decreased to (18.31±3.12) points at the fol ow-up after 1 month and (25.35±2.61) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). The preoperative VAS score was (8.24±1.15) points. The postoperative VAS score decreased to (2.97±1.12) points after 1 month and (1.13±0.39) points at the last fol ow-up, showing significant difference when compared with preoperative score (P<0.01). According to reforming Macnab standard, the results were excel ent in 53 cases and good in 9 cases at the last fol ow-up. The surgery including posterior lumbar spinal canal decompression, intervertebral disc resection, lumbar interbody fusion, and pedicle screw fixation via MAST Quadrant retractor is a safe, effective and minimal y invasive surgical technique in treating lumbar intervertebral disc protrusion concurring lumbar instability.

Objective:To explore the early warning value of carbapenem-resistant Klebsiella pneumoniae (CRKP) positivity in liver transplantation recipients with rectal swabs, examine the risk factors of CRKP bloodstream infection and provide the relevant treatments.Methods:From June 2018 to December 2019 in Organ Transplantation Research Institute Affiliated Tongji Hospital Tongji Medical College Huazhong University of Science & Technology, 148 cases of liver transplantation recipients with positive CRKP rectal swabbing were recruited. Clinical data were retrospectively analyzed. And the risk factors of CRKP bloodstream infections were examined for intervention and non-intervention groups to observe the effect of interventions of CRKP bloodstream infections.Results:Among them, 23 cases (15.5%) were positive for CRKP and 5 cases (21.7%) were infected with CRKP bloodstream. Rectal swab culture was negative in 125 cases and no bloodstream infection occurred. Long-term use of broad-spectrum antimicrobial agents, severe basic diseases (severe hepatitis), postoperative delayed graft liver function recovery, acute renal failure requiring renal replacement therapy (RRT) and postoperative anti-thymocyte globulin (ATG) induction were risk factors. In intervention group, there were 2 cases (11.1%) of 18 patients with positive CRKP in rectal swab culture in late stage. Among 5 CRKP-positive recipients without intervention, 3 cases (60%) developed later CRKP bloodstream infection. The incidence of bloodstream infection was significantly lower in intervention group than that in non-intervention group ( P<0.05). Conclusions:Rectal swab culture for liver transplantation recipients provides early warning for CRKP bloodstream infection. Interventions for CRKP positive high-risk recipients with rectal swab culture may reduce the occurrence of CRKP bloodstream infection and lower the risk of CRKP bloodstream infection in liver transplantation recipients.
