Abstract Background For thoracic segment esophageal range, Some think resect double side mediastinal pleura. other think never resection has no difference, increased complications. Methods This study used a prospective, randomized controlled study method. 213 patients with I-IIIA esophageal cancer were randomly divided into two groups. one group of 106 patients were completely removed with bilateral mediastinal pleura. Another group of 107 patients had the mediastinal pleura in the implementation; Both groups performed a thoracic lymph node dissection. we observed the incidence of pleural effusion, pulmonary infection rate, chest infection rate, OS, thoracic metastatic tumor incidence, and the postoperative review PET- CT. Results Among the 106 patients, there were 11 cases of pleural metastasis, 8 cases of chest infection and 33 cases of pulmonary infection, thoracic drainage tube pulling time averaged 3.8 days. After surgery three months, six months, one year, two years, 47 cases PET-CT are positive. an average 5-year survival rate of 47.3%. In other group, 15 patients with pleural metastases, 5 patients with chest infection, 19 in the lungs, thoracic drainage tube pulling time averaged 3.4 days. After surgery three months, six months, one year, two years, 43 cases PET-CT are positive and an average 5-year survival rate of 46,8%.. Conclusion This study is a prospective study on mediastinal pleural resection of esophageal cancer. Experimental conclusion found two groups of patients with pleural and pleural metastasis rate was not significant difference, and the chest cavity infection and pulmonary infection rate, less resection in patients with bilateral mediastinal pleura resection group is more, chest tube pull out two groups of almost the same time, there was no significant difference. Postoperative three months, six months, one year, two years PET-CT results, no significant difference in chest positive results. Patients with bilateral mediastinal pleural resection had a higher chest discomfort. In conclusion, it was concluded that there was no significant advantage in the surgical excision of bilateral mediastinal pleura in patients with esophageal cancer, and there were many complications. The sample size of this experiment is small, which is a single center study, and more large samples are needed. Disclosure All authors have declared no conflicts of interest.

Background and Aims: This study evaluated the prognostic value of 18F-fluorodeoxyglucose positron emission tomography with integrated computed tomography (18F-FDG PET/CT) performed before and after concurrent chemoradiotherapy (CCRT) in esophageal cancer. Methods: We analyzed the prognosis of 50 non-metastatic squamous cell esophageal cancer (T1-4N0-2) patients who underwent CCRT with curative intent at Inje University Busan Paik Hospital and Haeundae Paik Hospital from 2009 to 2019. Median total radiation dose was 54 Gy (range 34-66 Gy). Our aim was to investigate the relationship between PET/CT values and prognosis. The primary end point was progression-free survival (PFS). Results: The median follow-up period was 9.9 months (range 1.7-85.7). Median baseline maximum standard uptake value (SUVmax) was 14.2 (range 3.2-27.7). After treatment, 29 patients (58%) showed disease progression. The 3-year PFS and overall survival (OS) were 24.2% and 54.5%, respectively. PFS was significantly lower ( P = 0.015) when SUVmax of initial PET/CT exceeded 10 (n = 22). However, OS did not reach a significant difference based on maximum SUV ( P = 0.282). Small metabolic tumor volume (≤14.1) was related with good PFS ( P = 0.002) and OS ( P = 0.001). Small total lesion of glycolysis (≤107.3) also had a significant good prognostic effect on PFS ( P = 0.009) and OS ( P = 0.025). In a subgroup analysis of 18 patients with follow-up PET/CT, the patients with SUV max ≤3.5 in follow-up PET/CT showed longer PFS ( P = 0.028) than those with a maximum SUV >3.5. Conclusion: Maximum SUV of PET/CT is useful in predicting prognosis of esophageal cancer patients treated with CCRT. Efforts to find more effective treatments for patients at high risk of progression are still warranted.

Abstract Background Target volume definition of the primary tumor in esophageal cancer is usually based on computed tomography (CT) supported by endoscopy and/or endoscopic ultrasound and can be difficult given the low soft-tissue contrast of CT resulting in large interobserver variability. We evaluated the value of a dedicated planning [F18] FDG-Positron emission tomography/computer tomography (PET/CT) for harmonization of gross tumor volume (GTV) delineation and the feasibility of semiautomated structures for planning purposes in a large cohort. Methods Patients receiving a dedicated planning [F18] FDG-PET/CT (06/2011–03/2016) were included. GTV was delineated on CT and on PET/CT (GTVCT and GTVPET/CT, respectively) by three independent radiation oncologists. Interobserver variability was evaluated by comparison of mean GTV and mean tumor lengths, and via Sørensen–Dice coefficients (DSC) for spatial overlap. Semiautomated volumes were constructed based on PET/CT using fixed standardized uptake values (SUV) thresholds (SUV30, 35, and 40) or background- and metabolically corrected PERCIST-TLG and Schaefer algorithms, and compared to manually delineated volumes. Results 45 cases were evaluated. Mean GTVCT and GTVPET/CT were 59.2/58.0 ml, 65.4/64.1 ml, and 60.4/59.2 ml for observers A–C. No significant difference between CT- and PET/CT-based delineation was found comparing the mean volumes or lengths. Mean Dice coefficients on CT and PET/CT were 0.79/0.77, 0.81/0.78, and 0.8/0.78 for observer pairs AB, AC, and BC, respectively, with no significant differences. Mean GTV volumes delineated semiautomatically with SUV30/SUV35/SUV40/Schaefer’s and PERCIST-TLG threshold were 69.1/23.9/18.8/18.6 and 70.9 ml. The best concordance of a semiautomatically delineated structure with the manually delineated GTVCT/GTVPET/CT was observed for PERCIST-TLG. Conclusion We were not able to show that the integration of PET/CT for GTV delineation of the primary tumor resulted in reduced interobserver variability. The PERCIST-TLG algorithm seemed most promising compared to other thresholds for further evaluation of semiautomated delineation of esophageal cancer.

BackgroundClinically, many esophageal cancer patients who planned for radiation therapy have already undergone diagnostic Positron-emission tomography/computed tomography (PET/CT) imaging, but it remains unclear whether these imaging results can be used to delineate the gross target volume (GTV) of the primary tumor for thoracic esophageal cancer (EC).MethodsSeventy-two patients diagnosed with thoracic EC had undergone prior PET/CT for diagnosis and three-dimensional CT (3DCT) for simulation. The GTV3D was contoured on the 3DCT image without referencing the PET/CT image. The GTVPET-ref was contoured on the 3DCT image referencing the PET/CT image. The GTVPET-reg was contoured on the deformed registration image derived from 3DCT and PET/CT. Differences in the position, volume, length, conformity index (CI), and degree of inclusion (DI) among the target volumes were determined.ResultsThe centroid distance in the three directions between two different GTVs showed no significant difference (P > 0.05). No significant difference was found among the groups in the tumor volume (P > 0.05). The median DI values of the GTVPET-reg and GTVPET-ref in the GTV3D were 0.82 and 0.86, respectively (P = 0.006). The median CI values of the GTV3D in the GTVPET-reg and GTVPET-ref were 0.68 and 0.72, respectively (P = 0.006).ConclusionsPET/CT can be used to optimize the definition of the target volume in EC. However, no significant difference was found between the GTVs delineated based on visual referencing or deformable registration whether using the volume or position. So, in the absence of planning PET–CT images, it is also feasible to delineate the GTV of primary thoracic EC with reference to the diagnostic PET–CT image.

434 Background: PET-CT is considered as standard modality for evaluating metastasis of esophageal cancer before treatment. On the other hand, it is unclear whether PET-CT CMR (complete metabolic response) could be useful for assessment after neoadjuvant chemotherapy. To clarify the utility of PET-CT CMR as an adequate modality of prediction for recurrence after neoadjuvant chemotherapy with DCF for esophageal cancer. Methods: Fifty-eight cases of esophageal cancer (cStageII-IVa) who received the esophagectomy with neoadjuvant chemotherapy of DCF since June 2013 in Oita University. We evaluated the clinicopathological factors, RFS and OS between CMR group (n=22, 38%) and non-CMR group (n=36, 62%). Results: In the clinical stage before chemotherapy, T-factor was higher in the non-CMR group (p = 0.044), but there were no significant differences of lymph node metastasis (p = 0.27) and stage (p = 0.94) between the two groups. There was no significant difference of the SUV max (16.4 ± 6.5 vs 15.7 ± 6.5, p = 0.98) of the main lesion before chemotherapy and the FDG accumulation rate of lymph nodes (14 cases (63.6%) vs 21 cases) (58.3%), p = 0.69) between the two groups. There were no significant differences of the surgical procedure, lymph node dissection area, number of harvested lymph nodes, amount of bleeding, operation time, curability, and intra/post-operative complications between the two groups. There were 5 cases (15%) with postoperative recurrence in the CMR group (lung 1 case, extra-regional lymph nodes 3 cases, bone 1 case), 17 cases (47%) in the non-CMR group (local 4 cases, lung 3 cases, livers 5 cases, extra regional lymph nodes 6 cases, bone 4 cases, pleura 2 cases), but there was no significant difference between the two groups (p = 0.062). There were significant differences between the two groups for 3-year RFS (81.3 vs 65.3 months, p=0.021) and 3-year OS (93.8 vs 61.6 months, p=0.011). Conclusions: PET-CR CMR could not predict recurrence at present. PET-CR CMR cases had better prognosis compared to non-CMR cases in terms of 3-year RFS and 3-years OS.

Abstract Background Hypertensive intracerebral hemorrhage is one of the most common cerebrovascular diseases with high mortality and high disability rate. The aim of this study was to observe the curative effect of minimally invasive liquefaction and drainage of hypertensive putaminal hemorrhage (HPH) through frontal approach. Methods This study retrospectively reviewed the clinical data of 66 HPH patients who underwent surgery from January 2012 to January 2017 including 35 males and 31 females, aged 51 to 82 years, with an average age of 61.6 ± 7.32 years. All patients were treated in the first people’s hospital of Kunshan. They were divided into two groups: puncture thrombolysis and drainage therapy (PTDT) group and conventional craniotomy (CC) group. Result The pulmonary infection rate in PTDT group was 13.8%, significantly lower than that of 27.7% in CC group (p < 0.05). One year after onset, the modified Rankin scale (mRS) score of surviving patients was evaluated. The mRS score of the PTDT group with 30 to 60 mL of preoperative bleeding was 1.91 ± 0.82, which was significantly better than that of the CC group (2.21 ± 0.83) (p < 0.05). There was no significant difference in mRS score between PTDT group (2.59 ± 0.62) and CC group (2.88 ± 0.87) with preoperative bleeding > 60 mL (p > 0.05). In patients with Glasgow coma scale (GCS) 5 to 8 scores, the mRS of PTDT and CC groups were 2.73 ± 0.72 and 2.94 ± 0.96, respectively (p > 0.05). In patients with GCS 9 to 13 scores, the mRS score of PTDT group was 1.83 ± 0.69, which was significantly better than that of CC group (2.06 ± 0.74) (p < 0.05). Conclusion HPH can be treated effectively through PTDT. PTDT group has lower lung infection rate than CC group. And it can significantly improve the prognosis of patients with preoperative bleeding volume of 30 to 60 mL and preoperative GCS score of 9 to 13.

4052 Background: We compared the health-related quality-of-life (HRQOL) of standard neoadjuvant cisplatin and 5-FU chemotherapy plus radiotherapy (N) followed by surgical resection to adjuvant cisplatin, 5-FU, and epirubicin chemotherapy with concurrent extended volume radiotherapy (A) following surgical resection for resectable esophageal carcinoma. Methods: 96 patients with stage I to III resectable cancer of the esophagus were enrolled into a prospective randomized trial (NCT00907543) from April 2009 to November 2016. Patients were randomized into 2 groups: N (47 cases) and A (49 cases). The primary end point was HRQOL using the FACT-E at one year. The secondary endpoints included other HRQOL measures, overall survival (OS), disease-free survival (DFS), and adverse events. Results: The median follow-up was 5.0 years [95% CI :4.6 to 5.5]. The majority of patients had adenocarcinomas of the distal esophagus/gastroesophageal junction (80.9% vs 87.8%). The stage distribution was: I 9%; II 22%; III 58%; TxN0-1 10%. Using an intention-to-treat analysis there was no significant difference in the FACT-E total scores between arms at one year (p = 0.759), with 35.5% vs. 41.2% respectively showing an increase of ≥ 15 points ( a priori minimal clinical difference) compared to pre-treatment (p = 0.638). The HRQOL was temporarily significantly inferior at 2 months in the N arm for FACT-E, EORTC OG25, and EQ-5D-3L in the dysphagia, reflux, pain, taste, and coughing domains (p < 0.05). There were no 30-day mortalities but 2.1% vs. 10.2% 90-day mortalities (p = 0.204). There were no significant differences in either 5-year OS (37.9% vs 28.9%, p = 0.321) or DFS (34.0% vs 25.5%, p = 0.551. 48.9% of patients required chemotherapy to be modified or stopped in the N arm compared to 57.1% in the A arm (p = 0.421). 51.1% of patients were able to complete the prescribed N arm chemotherapy without modification compared to only 14.3% in the A arm (p < 0.001). Chemotherapy related adverse events significantly more frequent in the neoadjuvant arm (p < 0.05). Surgery related adverse events were significantly more frequent in the neoadjuvant arm (p < 0.05). Conclusions: Trimodality therapy is challenging for patients with resectable esophageal cancer regardless if it is given before or after surgery. Less toxic protocols are needed. Clinical trial information: 00907543.

Abstract. Background: The invasive management of varicose veins has a known risk of post-operative deep venous thrombosis and subsequent pulmonary embolism. The aim of this study was to evaluate absolute and relative risk of venous thromboembolism (VTE) following commonly used varicose vein procedures. Patients and methods: A retrospective analysis of secondary data using Hospital Episode Statistics database was performed for all varicose vein procedures performed between 2003 and 2013 and all readmissions for VTE in the same patients within 30 days, 90 days, and one year. Comparison of the incidence of VTEs between procedures was performed using a Pearson’s Chi-squared test. Results: In total, 261,169 varicose vein procedures were performed during the period studied. There were 686 VTEs recorded at 30 days (0.26 % incidence), 884 at 90 days (0.34 % incidence), and 1,246 at one year (0.48 % incidence). The VTE incidence for different procedures was between 0.15–0.35 % at 30 days, 0.26–0.50 % at 90 days, and 0.46–0.58 % at one year. At 30 days there was a significantly lower incidence of VTEs for foam sclerotherapy compared to other procedures (p = 0.01). There was no difference in VTE incidence between procedures at 90 days (p = 0.13) or one year (p = 0.16). Conclusions: Patients undergoing varicose vein procedures have a small but appreciable increased risk of VTE compared to the general population, with the effect persisting at one year. Foam sclerotherapy had a lower incidence of VTE compared to other procedures at 30 days, but this effect did not persist at 90 days or at one year. There was no other significant difference in the incidence of VTE between open, endovenous, and foam sclerotherapy treatments.

SummaryIncreased thrombin generation occurs in many individuals with inherited defects in the antithrombin or protein C anticoagulant pathways and is also seen in patients with thrombosis without a defined clotting abnormality. Hyperhomocysteinemia (H-HC) is an important risk factor of venous thromboembolism (VTE). We prospectively followed 48 patients with H-HC (median age 62 years, range 26-83; 18 males) and 183 patients (median age 50 years, range 18-85; 83 males) without H-HC for a period of up to one year. Prothrombin fragment Fl+2 (Fl+2) was determined in the patient’s plasma as a measure of thrombin generation during and at several time points after discontinuation of secondary thromboprophylaxis with oral anticoagulants. While on anticoagulants, patients with H-HC had significantly higher Fl+2 levels than patients without H-HC (mean 0.52 ± 0.49 nmol/1, median 0.4, range 0.2-2.8, versus 0.36 ± 0.2 nmol/1, median 0.3, range 0.1-2.1; p = 0.02). Three weeks and 3,6,9 and 12 months after discontinuation of oral anticoagulants, up to 20% of the patients with H-HC and 5 to 6% without H-HC had higher Fl+2 levels than a corresponding age- and sex-matched control group. 16% of the patients with H-HC and 4% of the patients without H-HC had either Fl+2 levels above the upper limit of normal controls at least at 2 occasions or (an) elevated Fl+2 level(s) followed by recurrent VTE. No statistical significant difference in the Fl+2 levels was seen between patients with and without H-HC. We conclude that a permanent hemostatic system activation is detectable in a proportion of patients with H-HC after discontinuation of oral anticoagulant therapy following VTE. Furthermore, secondary thromboprophylaxis with conventional doses of oral anticoagulants may not be sufficient to suppress hemostatic system activation in patients with H-HC.

Introduction: Deviated nasal septum is one of the most common causes for the nasal obstruction. The objective of this study is to compare the surgical outcomes in patients undergoing conventional septoplasty and endoscopic septoplasty in the management of deviated nasal septum. Methods:  Prospective comparative study was conducted on 60 patients who presented to the Department of ENT, College of Medical sciences, during a period of one year. The severity of the symptoms was subjectively assessed using NOSE score and objectively assessed using modified Gertner plate. Results: There was significant improvement in functional outcome like NOSE Score and area over the Gertner plate among patients who underwent endoscopic septoplasty. Significant difference in incidence of post-operative nasal synechae and haemorrhage was seen in conventional group compared to endoscopic group. Conclusions: Endoscopic surgery is an evolutionary step towards solving the problems related to deviated nasal septum. It is safe, effective and conservative, alternative to conventional septal surgery.
