Objective To evaluate the clinical value of laparoscopy in the diagnosis and treatment of intestinal duplication for children. Methods From June 2002 to May 2007, 15 children (aged 27 days to 10 years) with intestinal duplication were treated by laparoscopy in our hospital. The lesions were explored by laparoscopy, and then pulled out through the umbilical hole or the trocar hole at the right lower abdomen. The anastomosis was performed outside the abdominal cavity. Results The operation was successfully accomplished in all the patients. No serious postoperative complications occurred. Among the cases, end-to-end anastomosis was performed on 12 patients, resection of the duplicated intestine on 2, and demucosation on 1. Simultaneously, appendectomy was performed on 2 cases, and ring suturing for inguinal hernia on 1. The patients were followed up for 3-18 months (mean, 12 months), during which no patients had symptoms of intestinal adhesion (abdominal distension, vomiting), hemorrhage, or incisional hernia. Conclusions Laparoscopy is effective and reliable with a high diagnostic rate and low complication rate in the diagnosis and treatment of intestinal duplication for children.

Objective To investigate the clinical diagnosis and treatment of children's relapsesable intussusception by Peutz-Jeghers syndrome.Methods 5 cases of relapsesable intussusception result from Peutz-Jeghers syndrome which confirmed by operation and pathological diagnosis in children were analyzed retrospectively.Results All patients were diagnosed definitely by operation and pathological diagnosis and recovered well postoperatively.Conclusions Treated with the intussusception and resected polypus is effect to Peutz-Jeghers syndrome because it caused intussusception recurred easily,and patients should be followed up and examined regularly.

Objective To investigate the feasibility and clinical effect of transaxillary dual-plane breast augmentation under endoscope combined with autologous fat transplantation.Methods From January 2015 to December 2015,88 patients who accepted augmentation mammoplasty were divided into control group (from January to June) and observation group (from July to December).Patients in control group only accepted transaxillary dual-plane breast augmentation and transaxillary dual-plane breast augmentation combined with autologous fat transplantation was used for patients in observation group.Patients' basic information,surgery-related indicators,recovery situations,complications and patients' satisfactory data were collected.34 patients in control group and 38 patients in observation group were followed up.Results For surgery-related indicators and recovery situations,statistically significant difference was not found in the blood lost,duration of drainage tube and postoperative stay (P＞0.05),but was found in operation time (P＜0.05).And there was no significant difference in terms of surgical effects between two groups (P＞0.05).There were no complications such as hematoma,infection,capsular contracture in two groups.25 patients in observation group were performed B ultrasonic examination 6 months after operation.Multiple cysts were found at the cleavage in only 1 patient and were cured by suction.And the rest B ultrasonic results were negative for pathologic findings such as calcifications,cysts and masses.Conclusions Autologous fat transplantation is useful in minimizing the unaesthetic appearance of the cleavage and the bad feeling of the inframammary fold and thus a proper solution for the patient's breasts with thin soft tissue.

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 explore the nipple-areola complex blood supply mode in hypertrophic breasts, and to obtain the pertinent knowledge of vascular anatomy for breast reduction surgery as well as the analysis of similarities and differences between hypertrophic and normal breasts. Comparing the blood supply of nipples-areola complex between these two groups for analyzing their similarities and differences. Methods: Three dimensional reconstruction of the arteries in breast were performed in 50 patients between September 2015 and August 2017 with breast hypertrophy by computed tomographic angiography (CT angiography). The distribution pattern and the source direction of each main blood vessel was observed, counted and analyzed. Then, the data of breast hypertrophy patients were compared with the previous data about nipple-areola blood supply in normal population (the definition of main vessel: entering the breast gland or reaching the nipple-areola surrounding area, and diameter larger than 1 mm). Statistical description was taken for comparison. Results: 135 main vessels were observed in 100 breasts (50 patients). They mainly originate from the internal thoracic artery (69, 51.1%), lateral thoracic artery (37, 27.4%) and thoracoacromial artery(16, 11.9%), as well as a small amount from the brachial artery (7, 5.2%) and axillary artery(6, 4.4%). No main supply vessels from the posterior intercostal artery have been found. The patterns of breast blood supply varied among individuals, and high asymmetry ratio in the same individual was also observed. The internal superior (left: 30.7%, right: 34.2%) and superior lateral quadrant (Left: 29.2%, Right: 20%) of the breast was the most likely area for the main vessel to pass, followed by the breast lateral (Left: 16.9%, Right: 18.5%), lower inner (Left: 4.6%, Right: 5.7%), central (Left: 4.6%, Right: 4.2%), and superior (Left: 1.5%, Right: 2.8%). Differences existed in main vessels between normal breasts and hypertrophic breasts, either for source arteries or the distribution of breast. There was no main blood supply from the intercostal arteries or across the outer inferior quadrant. Conclusions The blood supply of the nipple-areola is not completely consistent between the hypertrophic breast and the normal size breast, and the blood supply pattern of the hypertrophic breasts is complex and diverse. CT angiography might be used before breast reduction surgery for clarifying the direction of the main vessels, so as to preserve more blood supply for nipple-areola, and to prevent nipple-areola necrosis.
