Objective To review the treatment of repair gastroschisis with autogenous umbilical cord and evaluate its effect. Methods Thirty newborns who underwent the repair gastroschisis with autogenous umbilical cord between August 1992 to October 2007, 26 cases survived under observed and followed-up, observing physical growth, intelligence measuring and whether the area of operated in abdomen need staged repair or not. Compared with 15 cases who underwent traditional operation method at the same time. Results Two cases died, 2 cases abandoned, and 26 ease received survive (survive rate 86.7%)and their growth was well in 26 cases. But in those 15 cases who underwent traditional operation method, 5 cases survived (survive rate 33.3%). There were significant difference in the survive rate, the mean operative time and postoperative hospital stay time between the two operation methods (P <0.05).Conclusion The material is adopted easily in the operation, autogenous umbilical cord is elastic tissue and no toxicity, it can relax the abdominal press effectively after the operation, the survive rate is high.

Objective:To investigate the feasibility, efficacy, and safety of CT- and bronchoscopy-guided 125I seed implantation in the treatment of central lung cancer complicated with atelectasis. Methods:Retrospective analysis was conducted on twenty-nine patients who were treated from May 2016 to Oct 2019 in the Second Hospital of Tianjin Medical University for central non-small-cell lung carcinoma complicated with pulmonary atelectasis that was inoperable due to medical reasons. 125I seeds were implanted into the trachea under the guidance of bronchoscopy first.The 125I seeds were then implanted into the hilum of the lungs by percutaneous puncture under the guidance of the CT and template.The seed activity was 18.5-29.6 MBq, and the prescription dose was 120 Gy.TPS planning and quality verification were performed before and after the operations.The rate of atelectasis recanalization, the satisfactory rate of dose verification, the improvement of dyspnea index, the survival time, and the adverse events during and after operation were observed. Results:All 29 patients with lung cancer complicated with atelectasis successfully completed the seed implantation, and the satisfactory rate of quality verification was 93.1%.The rate of atelectasis recanalization at 2, 6, 12, 18, and 24 months was 93.1%, 89.7%, 78.6%, 76.2%, and 60%, respectively.Their dyspnea and anoxia symptoms were significantly relieved in 5-28 months after treatment.The results showed that the patients′ dyspnea index was 2.8-0.8 before treatment and 1.4-0.9 after treatment.The median follow-up period was 20 months and median survival was 21 months.Adverse events associated with the radiation therapy included pneumothorax, hemoptysis, cough, fever, and particle displacement.No level-3 or more serious adverse events occurred.Conclusions:The CT- and bronchoscopy-guided 125I seed implantation is a safe and effective therapy option for the treatment of central non-small-cell lung carcinoma associated with atelectasis.It contributes to a high rate of local recanalization, and can rapidly improve clinical conditions and quality of life of the patients with few adverse reactions.

Objective To explore the feasibility and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis caused by operation of congenital esophageal atresia. Methods A retrospective analysis was performed on data of 218 children with type Ⅲ esophageal atresia, who underwent surgery in Zhengzhou Children' s Hospital from January 2009 to December 2017. The occurrence of postoperative complications and efficacy of endoscopic balloon dilation in treatment of esophageal stenosis was analyzed. Results Among the 218 patients with congenital esophageal atresia, 92 were type Ⅲa and 126 were type Ⅲb. Postoperative anastomotic leakage occurred in 46 cases (21. 1％), including 29 (31. 5％) of type Ⅲa and 17 (13. 5％) of type Ⅲb. Postoperative anastomotic stenosis occurred in 53 cases (24. 3％), including 29 ( 31. 5％) of type Ⅲa and 24 ( 19. 0％) of typeⅢb. The incidence of anastomotic leakage and anastomotic stenosis in different types was significantly different (χ2=10. 383, P=0. 001; χ2=4. 497, P=0. 034). The 53 cases of anastomotic stenosis underwent 123 times of endoscopic balloon dilation, with mean time of 3. 5±1. 6, and were finally clinically recovery. No esophagus perforation occurred. Among them, 29 cases of type Ⅲa underwent 73 times with mean of 4. 0±1. 8, and 24 cases of type Ⅲb underwent 50 times with mean of 2. 5±0. 7. The difference between the two types was statistically significant (t=-4. 053, P=0. 027). Conclusion Children with type Ⅲa esophageal atresia has a higher incidence of anastomotic stenosis and leakage, and more times of esophageal dilation. Endoscopic balloon dilation is safe and effective in treatment of esophageal stenosis after surgery for patients with congenital esophageal atresia.

Objective To investigate value of peripheral NLR and PLR for the survival of patients with neuroblastoma.Methods The clinical data of 41 neuroblastoma patients were analyzed by the Kaplan-Meier,Log-rank test,and multivariate COX regression.Results NLR,PLR levels of neuroblastoma patients were significantly higher than that in the healthy control group (1.81 ±0.29 vs.1.07 ±0.29,P ＜ 0.01) (169 ± 23 vs.76 ± 3,P ＜ 0.01);The elder the age,the higher the clinical stages,the higher the serum levels of NSE,and urine VMA were,the higher was the NLR (x2 =3.93,6.286,7.676,6.689,all P＜0.05) and PLR (x2 =4.111,5.707,8.019,8.922,all P ＜0.05).The higher the serum level of LDH,the higher was the NLR (x2 =7.769,P =0.02).3-year overall survival in low NLR group was 84％ and that in high NLR group was 73％ (x2 =4.002,P =0.045);3-year progression-free survival in low NLR group was 74％ and that in high NLR group was 50％ (x2 =4.082,P =0.043);3-year progression-free survival of low PLR group was 85％ and high PLR group was 38％ (x2 =9.388,P =0.002).The clinical stages,MYCN genetic expression,NLR levels were independent factors for the overall survial in patients with neuroblastoma (P ＜ 0.05).Conclusion Pretreatment NLR level can effectively predict the prognosis of neuroblastoma.

Objective To evaluate the safety and effectiveness of enhanced recovery after surgery (ERAS) in laparoscopic radical gastrectomy for gastric cancer.Methods From May 2015 to July 2017,149 patients with gastric cancer in our department were prospectively enrolled and randomly divided into the ERAS group (n =75) and control group (n =74).Results In ERAS group compared to control group,the time to first passage of flatus was (51 ± 11)vs.(62 ± 11)h,first feeding time (46 ± 12) vs.(68 ±20)h,gastric tube removal time (13 ± 12)h vs.(70 ± 16) h,pain score on the first day after surgery (3.9 ±1.3) vs.(5.2 ±0.9),C-reaction protein level (8.5 ±2.6) mg/L vs.(10.1 ±3.0)mg/L,post-op hospital stay (6.9 ± 2.9) d vs.(11.2 ± 3.5) d,were all significantly different (all P ＜ 0.05).The postoperative complication rates was 25％ vs.28％ respectively,(x2 =0.101,P =0.750).Conclusions Enhanced recovery after surgery can promote the postoperative recovery and shorten the time of hospitalization in laparoscopic-assisted radical gastrectomy for gastric cancer.

Objective To identify the risk factors for postoperative complications after radical resection of rectal cancer, and study the influence of high ligation of the inferior mesenteric artery on postoperative complications of rectal cancer. Methods Clinical data of the patients who underwent radical resection of rectal cancer in the Affiliated Hospital of North Sichuan Medical College from January 2011 to December 2015 were analyzed. The χ 2test and t test were used for all the data. Results A total of 431 patients with rectal cancer were included, of which 80 cases were excluded, and finally 351 cases met the standard. Among them, 196 cases were in high ligation group, and 155 cases were in low ligation group. The total incidence of postoperative complications was 20.4 %(40/196) in the high ligation group and 27.1 %(42/155)in the low ligation group respectively,the difference of which was not statistically significant(χ2=1.336, P= 0.245). The incidence of anastomotic leakage was 10.2 % (20/196) in the high ligation group and 7.7 % (12/155) in the low ligation group respectively, and there was no significant difference between them (χ2=0.529, P= 0.467). Logistic regression analysis revealed that gender (OR= 2.102, 95 % CI 1.278-3.459, P=0.003), body mass index (OR= 2.492, 95 % CI 1.070-5.800, P= 0.027), with or without anemia before surgery(OR=2.203,95 % CI 1.085-4.472,P=0.029), and location of tumor(OR=2.861, 95 % CI 1.288-16.007,P=0.019) were independent risk factors for postoperative complications. Conclusions High ligation of the inferior mesenteric artery does not increase the incidence of postoperative complications after radical resection of rectal cancer. Anastomotic leakage after rectal cancer resection is related to gender, body mass index,with or without anemia before surgery,and location of tumor.

Objective To study the clinical value of enhanced recovery after surgery (ERAS) in the perioperative treatment of type Ⅰ (Todami,1975) biliary dilatation (BD) of children.Methods To retrospectively analyze the data of children with type Ⅰ BD who were treated in the General Surgery Department of Zhengzhou Children's Hospital from June 2014 to May 2018.A total of twenty children with type Ⅰ BD treated with ERAS and 20 children treated with the traditional method in our department were selected in this study using the random number table method.Postoperative indicators (including operation time,first defecation time,changes in amylase in blood and abdominal cavity exudates,length of hospital stay,and hospitalization fee) and relevant postoperative complications (including sore throat,nausea and vomiting,urethral pain,upper respiratory tract infection,incision wound infection,adhesive intestinal obstruction,anastomotic leakage and pancreatic fistula) of the ERAS group and the control group were compared.Results The first defecation time,length of hospital stay and hospitalization fee were significantly lower in the ERAS group than the control group (all P ＜ 0.05) [first defecation time (1.98 ± 0.25) d vs.(2.25 ± 0.31) d;length of hospital stay (6.91 ± 1.25) d vs.(9.95 ± 1.53) d;hospitalization fee (23.32 ± 2.25)thousand yuan vs.(25.99 ±3.10) thousand yuan].Moreover,the incidences of sore throat,nausea and vomiting,urethral pain and upper respiratory tract infection were significantly lower in the ERAS group than the control group (all P ＜ 0.05) [the incidences of sore throat (5.0％ vs.45.0％);the incidences of sickness and vomiting (5.0％ vs.30.0％);the incidences of urethral pain (5.0％ vs.45.0％);the incidences of upper respiratory tract infection (5.0％ vs.40.0％)].On the other hand,there were no significant differences in the mean operation times,changes in amylase levels in the blood or abdominal cavity exudates,incision wound infection,and incidences of adhesive intestinal obstruction,anastomotic leakage and pancreatic fistula (all P ＞ 0.05).Conclusions ERAS for type Ⅰ BD surgery was safe and reliable in children.It effectively promoted recovery of postoperative gastrointestinal function and reduced the incidence of complications.
