Objective Compare the effect of thoracic and abdominal mediastinal tube placement on pain and comfort in patients with minimally invasive esophageal cancer and nursing care. Methods 108 patients with squamous cell carcinoma of the thoracic esophagus were selected from December 2016 to May 2017. The patients were divided into chest group and abdominal group according to the random number comparison table, each with 54 cases. All patients underwent minimally invasive radical resection of esophageal carcinoma. The mediastinum drainage tube was placed at different locations of the chest and abdomen after operation. The duration of intubation, total drainage volume, number of dressing change before and after extubation, degree of pain and comfort after surgery were recorded, drainage tube failure and the incidence of related complication were compared between the two groups. Results There was no significant difference in duration of intubation, total drainage volume, drainage tube failure and the incidence of related complication between Patients with mediastinal tubes placed through the chest and abdomen(P>0.05). The times of dressing change before and after extubation in the abdominal group were (2.8 ± 1.0), (1.9 ± 0.6) times, those in the chest group were (4.5 ± 1.2), (3.6 ± 1.1) times, there were significant difference between the two groups (t=7.841, 9.377, P<0.01). The NRS and VAS score at 1-4 days and extubation in the abdominal group were significantly lower than those in the chest group, the abdominal group were (3.2±1.0), (2.7±0.8), (2.3±0.7), (1.9±0.7), (1.5±0.6) points and (3.7±0.8), (3.4±1.4), (3.0± 0.7), (2.6±1.0), (2.6±1.0) points, the chest group were (3.7±1.3), (3.3±1.1), (2.8±0.8), (2.3±0.8), (2.3±0.7) points and (5.0±0.9), (4.3±1.4), (4.1±1.3), (3.3±1.2), (3.6±1.0) points, there were significant difference between the two groups (t=2.443-7.247, P<0.01 or 0.05). Conclusions Intraoperative abdominal minimally invasive radical mediastinal tube placed esophageal cancer, can significantly relieve pain and improve patient comfort, reduce the frequency of dressing change before and after extubation, not only quickly improve the rehabilitation of patients, but also can avoid the waste of medical resources, it is worthy of clinical promotion.

Objective To investigate the feasibility of sodium glycididazole(CMNa)on the radio-sensitization of esophageal cancer(EC)by 18F-fluoromisonidazole(FMISO)PET/CT.Methods A total of 60 patients with EC from December 2016 to December 2017 were enrolled prospectively and were divided into control group(n = 30;21 males,9 females;age:(56.6±10.0)years)and experimental group(n=30;20 males,10 females;age:(59.3±9.0)years)using completely randomized grouping design.Patients in the control group received radiotherapy alone,and those in the experimental group were treated with conventional radiotherapy and CMNa.All patients underwent 18F-FMISO PET/CT imaging 1 week before and after radiotherapy.The imaging results were visually and semi-quantitatively analyzed.The maximum standardized uptake value(SUVmax),tumor/muscle ratio(T/M),and hypoxia volume(HV)were calculated.Paired t test,two-sample t test and/x2 test were used to analyze the data.Results T/M and HV in the control group before and after radiotherapy were 3.92±0.57 vs 1.66±0.35,(1.84±0.31)vs(1.04±0.15)mm3,respectively;T/M and HV in the experimental group before and after radiotherapy were 4.01±0.68 vs 1.27±0.11,(2.01±0.22)vs(0.90±0.09)mm3,respectively.The primary tumor T/M,HV after radiotherapy in 2 groups were significantly lower than those before radiotherapy(t values:12.15-24.43,all P<0.05)and the amplitudes of T/M and HV in the experimental group were significantly higher than those in the control group(?T/M:2.77±0.60vs 2.25±0.49,?HV:(1.12±0.18)vs(0.81±0.26)mm3;t values:3.00 and 1.80,both P<0.05).Meanwhile,the local control rate of EC after 3 months in the experimental group was higher than that in the control group(80.0%(24/30)vs 53.3%(16/30);x2=4.80,P<0.05).Conclusion CMNa has the radiosensitizing effect on EC and the 18F-FMISO PET/CT can evaluate the radiosensitization effect.
