Objective:To explore the clinical value of extra-long subcutaneous tunnel ventricular drainage in patients with hydrocephalus.Methods:From March 2016 to March 2020, 33 patients who were not suitable for ventriculoperitoneal shunt, who would have expected time of external ventricular drainage longer than 7 d, who had external ventricular drainage reaching for 7 d and still could not expect for drainage tube drawing for the next 7 d, or who had hydrocephalus after external ventricular drainage were chosen in our study. These patients accepted extra-long subcutaneous tunnel ventricular drainage. The curative effects in the patients were analyzed retrospectively.Results:The drainage tube was kept for a maximum of 24 months and the shortest time was 13 d, with average of 69.3 d; 32 patients (97%) had drainage time longer than 14 d. There was no secondary infection after operation.Conclusion:Extra-long subcutaneous tunnel extraventricular drainage tube has a long duration of catheter placement, could avoid multiple drainage and secondary intracranial infection, so it is a safe and effective new technology for hydrocephalus.

Objective:To Investigate the application strategy and effect of cuffed tracheostomy tube with inner cannula in the treatment of postoperative complications of laryngeal and hypopharyngeal cancer.Methods:A total of 60 patients with laryngeal and hypopharyngeal cancer occurred serious postoperative complications, including 31 cases of severe postoperative neck infection, 8 cases of dyspnea, 5 cases of massive hemorrhage and 16 cases of seriously intractable aspiration. The tracheal cannula with inner cannula and outer cuff was immediately worn on these patients and the cuff was inflated. Different treatments were carried out according to different complications. The outer cuffs were inflated for patients with severe neck infections to prevent a large amount of neck secretions inhaled to the trachea. Patients with dyspnea immediately received ventilator-assisted ventilation. For those with massive hemorrhage on the wound, doctors should prevent bleeding and stop bleeding under general anesthesia. Patients with severely coughing should perform eating training to prevent food aspiration. The inner cannula was regularly replaced once a month for all of these patients.Results:Through targeted treatment, the complications of 60 patients with cuffed tracheostomy tube with inner cannula were effectively controlled. After dressing change, the neck wounds of 31 patients with neck infection were shrunk or healed. Finally, all of the patients were replaced with metal tracheal tubes. Eight cases with dyspnea were rescued with the symptomatic and related special treatment, and finally replace by metal tracheal tube. Five cases with massive bleeding in the neck wound were successfully rescued and replaced with metal tracheal cannula. Thirteen patients among 16 cases with intractable aspiration were removed the tracheal cannula and other 3 cases of old and severely ill were replaced with metal tracheal cannula.Conclusions:The cuffed tracheostomy tube with inner cannula is of great value in the treatment of severe postoperative complications of laryngeal or hypopharyngeal cancer. It is strongly recommended that the operators should fully understand and use it reasonably after the operation of laryngeal or hypopharyngeal cancer.

OBJECTIVE: To systematically evaluate the efficacy and safety of harmonic scalpel in neck dissection. METHOD: Available literatures of PubMed, EMBASE, Cochrane Library, Google Scholar, CBM, CNKI, WangFang and VIP published before June 2014 were searched. Inclusion criteria and quality assessment were performed. All data were analyzed by using RevMan 5.2 software. RESULT: Fourteen studies including 632 cases were enrolled. Among them, 319 cases were in harmonic scalpel group and 313 cases in conventional resection group. Compared with conventional resection group, the harmonic scalpel group showed shorter surgery time(weighted mean difference [95% confidence intetval]: -28.01 [-36.83, -19.19], Z = 6.22, P < 0.01)and less intra-operative blood loss (weighted mean difference [95% confidence intetval]: -46.68 [-57.25, -36.12], Z = 8.66, P < 0.01). The number of cervical lymph nodes dissected and the incidence of postoperative chylous leakage were similar in both groups. CONCLUSION Using the harmonic scalpel in neck dissection was as efficient and safe as that of the conventional technique with the advantage of shorter time of surgery and less intraoperative blood loss.
