Objective To introduce the preliminary experience of using rigid neuroendoscope in repair of spinal meningocele or myelomeningocele. Methods 3 infantile patients aging between 13 months and 22 months underwent the resection and repair of spinal meningocele or myelomeningocele in May, 2013. The operations were performed under the direct visualization of the rigid neuroendoscope in the aid of the intraoperative electrophysiological monitoring. All the surgical manipulations were accomplished outside the sheath of the endoscope. Results The surgical procedures were smooth. All the patients recovered satisfactorily. There was no postoperative complication. At the one-year follow-up, they were developing normally. Conclusions The rigid neuroendoscope is useful to the resection and repair of spinal meningocele and myelomeningocele. It could simplify the surgical procedures.

Objective:To explore the effects of quality control circle(QCC) on the complaint management and patient satisfaction in the medical insurance center.Methods:We set up QCC,defined the subject,identified the problems and made the cause analysis,made the countermeasures and implemented them.Results:Mter QCC ac-tivities,patients'major unsatisfactory factors such as long waiting time and poor staff coordination ability were signif-icantly improved.In addition,patient complaints decreased significantly (P ＜ 0.01).Conclusion:The application of QCC management on patient complaints can not only increase patient satisfaction,but also provide an importantway for the hospital to build up the brand.

Objective To investigate the clinical features,diagnosis and treatment of medullary thyroid microcarcinoma (MTMC).Methods The clinical data of 14 patients with MTMC from Mar.2012 to Sep.2016 were retrospectively reviewed.All cases were treated with surgery and pathologically proved to be MTMC.Results All patients were sporadic MTMC.Calcitonin and CEA levels were measured before surgery in 11 patients.The median values were 81.61 (3.36-1187) pg/ml and 7.42 (0.81-90.75) ug/ml,respectively.All patients were followed up postoperatively.During a median follow-up of 24 months (8-63 months),no death happened.Regional lymph node metastasis occurred in 8 patients (57.14％),and lateral lymph node metastasis in 5 cases (35.71％).The rate of postoperative calcitonin abnormal was significantly higher in patients with lateral lymph node metastasis (P＜0.01).6 cases (42.86％) had abnormal postoperative calcitonin,among whom 5 cases had preoperative baseline calcitonin level higher than 100 pg/ml.Patients having abnormal postoperative calcitonin suffered from higher calcitonin and CEA baseline (P＜0.05).The tumor size was similar in two groups (P＞0.05).Conclusions For patients with thyroid nodules,preoperative screen of calcitonin can effectively detect MTC.Patients with elevated CEA also need to exclude the possibility of MTC.Compared with tumor size,calcitonin baseline is more important to surgical options and postoperative outcomes.Lateral lymph node metastasis,baseline calcitonin ＞100 pg/ml indicates abnormal postoperative calcitonin.

Objective To evaluate the role of cabon nanoparticles for dissecting lymph nodes and preserving parathyroid glans in patients with differentiated thyroid carcinoma undergoing total thyroidectomy plus bilateral central neck dissection.Metheds From Sep.2015 to Feb.2016,100 patients in Rui Jin Hospital Affiliated to Shanghai Jiao Tong University School of Medicine with thyroid carcinoma undergoing primarily total thyroidectomy plus bilateral central neck dissection were randomly divided into carbon nonoparticle group and the contol group.The numbers of total dissected lymph nodes,the lymph node posterior to fight recurrent laryngeal nerve,metastasized lymph nodes,inadvertent parathyroidectomy,the parathyroid hormone and serum total calcium were measured.Results The average counts of lymph nodes in carbon nonoparticle group (10.96±5.43)were more than those in the control group at (8.22±4.40)lymph nodes,(t＝2.78,P＝0.01).The average counts of lymph node posterior to fight recurrent laryngeal nerve in carbon nonoparticle group (1.62±1.95)were more than those in the control group at (0.76±1.21)lymph nodes,(t＝2.66,P＝0.01).The numbers of metastasized lymph nodes was 2.02±2.40 in carbon nonoparticle group and 1.84±2.61 in the control group.The difference had no statistical significance(t＝0.36,P＞0.05).The amount of PTH and the decrease of PTH discrepancy one day after surgery between the two groups had no statistical difference (t＝0.23,P＞0.05),(t＝l.04,P＞0.05).The carbon nonoparticle group had 2％(1/50)mistakenly parathyroid gland removed incidence,on contrary,the control group had 6％(3/50)mistakenly removed incidence.The difference had no statistical significance(x2＝0.26,P＞0.05).Conclusion Carbon nonoparticle can improve the central lymph node detection rate,but the protection of the parathyroid glands is more likey to depend on the experience of the operator and the vascular protection.
