PURPOSE:The purpose of this study was to investigate the effectiveness and safety of the operation for type III esophageal atresia using a thoracoscope. METHODS:The clinical data for 92 patients with type III esophageal atresia in our hospital from January 2015 to December 2018 were analyzed retrospectively. There were 49 patients in group A who underwent thoracoscopic surgery and 43 patients in group B who underwent conventional surgery. RESULTS:The mechanical ventilation time (55.7 ± 11.4 h vs 75.6 ± 19.2 h), intensive care time (3.6 ± 1.8d vs 4.7 ± 2.0d), postoperative hospitalization time (13.1 ± 2.2d vs 16.8 ± 4.3d), thoracic drainage volume (62.7 ± 25.5 ml vs 125.4 ± 46.1 ml), blood transfusion volume (30.5 ± 10.4 ml vs 55.3 ± 22.7 ml) and surgical incision length (2.0 ± 0.5 cm vs 8.0 ± 1.8 cm) in group A were lower than those in group B, and the differences were statistically significant (P < 0.05). Among the postoperative complications, the incidences of postoperative severe pneumonia (8.2% vs 23.3%), poor wound healing (2.0% vs 14.0%) and chest wall deformity (0% vs 11.6%) in group A were significantly lower than those in group B (P < 0.05). There was no significant difference in the incidence of anastomotic stricture, tracheomalacia or gastroesophageal reflux between the two groups after surgery and early during follow-up (P > 0.05), and there were no complications such as achalasia signs and esophageal diverticulum in either group. CONCLUSION:Surgery for type III esophageal atresia via thoracoscopy has the same safety and clinical effectiveness as traditional surgery and has the advantages of smaller incision and chest wall deformity.

METHODS:PURPOSE:The purpose of this study was to compare the survival and toxicities in cervical esophageal squamous cell carcinoma (CESCC) treated by concurrent chemoradiothrapy with either three-dimensional conformal radiotherapy (3D-CRT) or intensity-modulated radiotherapy (IMRT) techniques. Materials and Methods:A total of 112 consecutive CESCC patients were retrospectively reviewed. 3D-CRT and IMRT groups had been analyzed by propensity score matching method, with sex, age, Karnofsky performance status, induction chemotherapy, and tumor stage well matched. The Kaplan-Meier method and Cox proportional hazards model were used for overall survival (OS) and progression-free survival (PFS). Toxicities were compared between two groups by Fisher exact test. RESULTS:With a median follow-up time of 34.9 months, the 3-year OS (p=0.927) and PFS (p=0.859) rate was 49.6% and 45.8% in 3D-CRT group, compared with 54.4% and 42.8% in IMRT group. The rates of grade ≥ 3 esophagitis, grade ≥ 2 pneumonitis, esophageal stricture, and hemorrhage were comparable between two groups, while the rate of tracheostomy dependence was much higher in IMRT group than 3D-CRT group (14.3% vs.1.8%, p=0.032). Radiotherapy technique (hazard ratio [HR], 0.09; 95% confidence interval [CI], 0.01 to 0.79) and pretreatment hoarseness (HR, 0.12; 95% CI 0.02 to 0.70) were independently prognostic of tracheostomy dependence. CONCLUSION:No survival benefits had been observed while comparing IMRT versus 3D-CRT in CESCC patients. IMRT with fraction dose escalation and pretreatment hoarseness were considered to be associated with a higher risk for tracheostomy dependence. Radiation dose escalation beyond 60 Gy should be taken into account carefully when using IMRT with hypofractionated regimen.

METHODS::The radial force of esophageal stents may not completely change during extraction and therefore, the procedure of stent removal may cause tissue damage. The present study reports the manufacture of 2 novel detachable stents, which were designed to reduce tissue damage through their capacity to be taken or fall apart prior to removal and evaluated the supporting properties of these stents and the extent of local mucosal injury during their removal. The stents were manufactured by braiding, heat-setting, coating and connecting. The properties of the stents were evaluated by determining the following parameters: Expansion point, softening point, stent flexibility, radial compression ratio and radial force. A total of 18 rabbits with induced esophageal stricture were randomly assigned to 3 groups as follows: Detachable stent (DS) group, biodegradable stent (BS) group and control group. The stricture rate, complications, survival, degradation and stent removal were observed over 8 weeks. The stents of the DS and BS groups provided a similar supporting effect. The stricture rate, incidence of complications and survival were also similar between the 2 groups, while significant differences were noted between the DS and control groups and between the BS and control groups. In the BS group, the stents were degraded and moved to the stomach within 7 weeks (2 in 6 weeks and 3 in 7 weeks). The debris was extracted using biopsy forceps. In the DS group, all stents were easy to remove and 2 cases exhibited minor hemorrhage. In conclusion, the 2 types of novel detachable stent provided an equally efficient supporting effect in vitro and in vivo and may reduce the incidence of secondary injury during stent removal.

METHODS:BACKGROUND:Immune imbalance and inflammation have been suggested as key factors of Barrett's esophagus (BE) pathway towards adenocarcinoma. The neutrophil-lymphocyte ratio (NLR) indirectly reflects the relation between innate and adaptive immune systems and has been studied in premalignant conditions as a biomarker for cancer diagnosis. Our aim was to investigate if increasing values of NLR correlated with advancing stages of BE progression to dysplasia and neoplasia. METHODS:We retrospectively analyzed data of patients with biopsies reporting BE between 2013 and 2017 and with a complete blood count within 6 months from the endoscopy, as well as patients with esophageal adenocarcinoma (EAC). NLR was calculated as neutrophil count/lymphocyte count. Cases (n = 113) were classified as non-dysplastic BE (NDBE, n = 72), dysplastic BE (DBE, n = 11) and EAC (n = 30). RESULTS:NLR progressively increased across groups (NDBE, 1.92 ± 0.7; DBE, 2.92 ± 1.1; EAC 4.54 ± 2.9), with a significant correlation between its increasing value and the presence of dysplasia or neoplasia (r = 0.53, p  2.27 was able to diagnose EAC with 80% sensitivity and 71% specificity (area under the curve = 0.8). CONCLUSION:NLR correlates with advancing stages of BE progression, a finding that reinforces the role of immune imbalance in EAC carcinogenesis and suggests a possible use of this marker for risk stratification on surveillance strategies.
