Objective To compare the long-term efficacies of anterior cervical decompression and fusion (ACDF)and conservative therapy in treatment of unisegmental cervical disc herniation and to analyze the degree of the long-term adjacent segment disc degeneration in ACDF.Methods 120 patients treated in our hospital from January 2006 to January 2009 were selected,60 patients underwent ACDF as operation group and 60 patients underwent physical therapy and drug (conservative therapy)as non-operation group. All the patients were recorded when they were diagnosed with cervical unisegmental cervical disc herniation, and followed-up for 60 months, and they were evaluated with American Spinal Injury Association (ASIA)score,Visual Analogue Scale (VAS),Japanese Orthopedics Association (JOA) score and imaging (Miyazaki grading system). Results 107 patients were followed up,55 patients treated by operation were followed up for an average 59.7 months (59.7±0.4),while 52 patients treated by conservative therapy were followed up for an average 58.8 months (58.8±1.5).Compared with before treatment, the ASIA, JOA, and VAS scores of the patients in two group after treatment were improved (P<0.05),and the scores of ASIA,VAS,and JOA in operation group were superior to that in non-operation group (P<0.05),and adjacent segment disc degeneration occurred more frequently in the upper adjacent segment than the lower adjacent segment (P<0.05).Conclusion ACDF is superior to conservative therapy in alleviating symptoms and improving prognosis of unisegmental cervical disc herniation. Long-term postoperative disc degeneration mainly occurrs in the upper segment.

Objective:To investigate the effect of different drainage methods on pancreatic fistula after pancreaticoduodenectomy (PD).Methods:The data of all patients with PD in Xijing Hospital, the First Affiliated Hospital of the Fourth Military Medical University from January 2007 to December 2018 were retrospectively analyzed. A total of 670 patients were enrolled, including 415 males and 255 females, aged (58.4±7.3) years, ranging from 24 to 82 years. According to the different method of pancreatic duct drainage, the propensity score was matched, and the patients were divided into internal drainage group ( n=529) and external drainage group ( n=141). The pancreatic fistula rate was compared between the two groups. Factors influencing pancreatic fistula after PD were analyzed by univariate and multivariate logistic regression. Results:The incidence of pancreatic fistula in the internal drainage group was 12.5% (66/529), which was significantly higher than that in the external drainage group 6.4% (9/141) (χ 2= 4.16, P=0.041). Multivariate logistic regression analysis showed that age ≥65 years ( OR=2.004, 95% CI: 1.185-3.390), complicated with digestive diseases ( OR=3.087, 95% CI: 1.599-5.959), history of upper abdominal surgery ( OR=2.031, 95% CI: 1.104-3.734) increased the risk of pancreatic fistula after PD (all P<0.05), decreased the risk of pancreatic fistula after PD in patients with external drainage ( OR=0.470, 95% CI: 0.223-0.989, P=0.047), and decreased the risk of pancreatic fistula after PD with the tumor size ( OR=0.725, 95% CI: 0.556-0.944, P=0.017), tumor located in the common bile duct after PD increased the risk of pancreatic fistula ( OR=1.497, 95% CI: 1.192-1.880, P=0.001). Conclusions:Compared with pancreatic duct drainage, external pancreatic duct drainage is better because of preventing postoperative pancreatic fistula.
