Abstract: Objective To Evaluate the clinical outcome of gastric tube in radical surgeries to treat esophageal and cardial carcinoma. Methods From January to October 2008, 74 patients with esophageal or cardial carcinoma in Ruijin Hospital were enrolled in our study. Based on the surgical method, they were divided into the gastric tube group and the traditional way group. The gastric tube group had 46 patients, including 36 male patients and 10 female patients, whose age averaged 59.67±9.96 years (36 to 77 years). Among them, 31 patients had esophageal carcinoma with 1 upper, 23 middle and 7 lower esophageal carcinoma, and 15 patients had cardial carcinoma. In this group, 2 patients were treated with anastomosis in the left neck, 19 with anastomosis in the upper aortic arch, 10 with anastomosis in the lower aortic arch and 15 cardial carcinoma patients underwent radical resection. In the traditional way group, there were 28 patients, 25 male patients and 3 female patients, whose age averaged 59.17±11.33 years (37 to 86 years). In these patients, 22 had esophageal carcinoma with 1 in the upper esophagus, 17 in the middle esophagus, 4 in the lower esophagus; and 6 patients had cardial carcinoma. In this group, 2 patients were treated with anastomosis in the left neck , 17 with anastomosis in the upper aortic arch, 3 with anastomosis in the lower aortic arch, and 6 cardial carcinoma patients underwent radical resection. The rate of anastomotic leakage, operation time, and length of stay in hospital of these two groups were observed. Results All surgeries in the two groups were successfully performed. There was no anastomotic leakage case in the gastric tube group, while there were 4 pulmonary infection cases and 1 death case in the traditional way group. There was no statistically difference in the operation time (180.00±10.34 min vs. 185.00±6.23 min, t=1.669, P=0.078) and length of stay in hospital (16.78±9.98 d vs. 16.89±11.53 d, t=1.665, P=0.075) between the gastric tube group and the traditional way group. Conclusion Gastric tube has a good value in clinical application with fewercomplications and without prolonging operation and hospitalization time, which can surely better quality of life of the patients.
ObjectiveTo compare the complication morbidity of mechanical and hand-sewn esophagogastric anastomosis systemically. MethodsMedline (January 1960 to June 2015), EMbase (January 1980 to June 2015), Cochrane Library (January 1996 to June 2015), Web of Science (January 1980 to June 2015) and other databases were searched to identify randomized controlled trials (RCTs) about comparing the complication morbidity of hand-sewn and mechanical anastomosis. Moreover, the references were searched by search engines such as Google Scholar. Papers were screened according to the inclusion and exclusion criteria. And then the data were extracted. The quality of current meta-analysis was assessed by GRADE profiler 3.6 software. The meta-analysis was conducted using Stata 12.0 software. ResultsA total of 1 611 patients in 14 RCTs were reviewed. The results suggested that the anastomatic leakage rate of mechanical method showed no significant difference from that of hand-sewn method[RR=1.07, 95%CI (0.76, 1.51), P=0.699]. While the anastomatic stenosis rate was even higher[RR=1.59, 95%CI (1.21, 2.09), P=0.001]. ConclusionMechanical method can't reduce the anastomotic leakage rate following esophagogastrostomy, while it maybe increase the risk of anastomotic stenosis on the contrary. The patients' physical condition should be considered when surgeons make the choice.
Objective To assess clinical outcomes of therapeutic video-mediastinoscopy （VMS）. Methods Clinical data of 82 patients undergoing VMS in Zhongshan Hospital of Dalian University from December 2008 to October 2011 were retrospectively analyzed. Among them，24 patients received therapeutic VMS，including 18 men and 6 women with their median age of 56 （22-81） years. Three patients underwent operation through a neck incision，4 patients through a parasternal incision，and 17 patients through a lateral intercostal incision. Five patients received local anesthesia and basal anesthesia，and all the other patients received general anesthesia through single-lumen or double-lumen endotracheal intubation. Results Twelve patients with pleural effusion underwent pleural or lung biopsy and talc pleurodesis. Pathology examination showed malignant diseases in 11 patients and tuberculous pleural effusion in 1 patient. The median operation time was 35 （30-50） minutes，and postoperative hospital stay was 3-6 days. These patients were followed up for 1 month without recurrence of pleural effusion. Ten patients with mediastinal mass received pathological diagnosis and complete mass resection with their median operation time of 55 （30-270） minutes and median hospital stay of 7 （5-40） days. Two patients with hyperhidrosis underwent bilateral intercostal VMS sympathectomy. Their operation time was 60 minutes and 50 minutes respectively，and their hospital stay was 3 days. Postoperatively their sweating symptoms obviously resolved. They were followed up for 3 months，and their hands，feet and armpit were warm and dry. There was no in-hospital death in this group. Two patients （8.3%） had postoperative complications including 1 patient with phrenic nerve injury and another patient with pneumonia. Opioid analgesic drugs were not used postoperatively in 9 patients. Conclusion Therapeutic VMS is a safe，effective，minimally invasive and cosmetic procedure，but it is not suitable for resection of a large mediastinal mass.
Objective To summarize the experiences of applying gastric tube in minimally invasive esophagectomy (MIE), in order to assess its feasibility and safety. [WTHZ]Methods From June 2004 to August 2009, MIE was performed on 102 patients with esophageal carcinoma, including 71 males and 31 females whose age ranged from 37 to 79 years old with an average age of 61.1. Among them, 62 patients underwent thoracoscopic laparotomy 3-incision esophagectomy, 35 patients underwent thoracoscopic and laparoscopic 3-incision esophagectomy and 5 patients underwent thoracotomy and laparoscopic esophagectomy. Prevertebral reconstruction was performed on 58 patients and retrosternal reconstruction was performed on 44 patients. [WTHZ]Results All operations were performed successfully with a perioperative mortality rate of 2.0%(2/102) and a postoperative complication rate of 41.2%(42/102). The complications included anastomotic leakage, anastomotic stricture and lung infection. The complication rate was higher in the retrosternal group than in the prevertebral group (56.8% vs. 29.3%, Plt;0.05). Anastomotic leakage rate in the retrosternal group was also higher than that in the prevertebral group (34.1% vs. 6.9%, Plt;0.05). There was no significant difference in anastomotic stenosis, gastric fistula, dysfunction of gastric emptying, heart and lung complications, chylothorax and injury of recurrent laryngeal nerve between the two groups. [WTHZ]Conclusion Gastric tube is an effective way for reconstruction of the digestive tract after minimally invasive esophagectomy. The choice of prevertebral reconstruction or retrosternal reconstruction should be based on each individual patient.
Abstract: Objective To investigate the expression of inhibitor of apoptosis gene Livin and its relationship with expression of P53,Bcl-2 in esophageal carcinoma tissues. Methods The expression of Livin messenger ribonucleic acid (mRNA) in 36 esophageal carcinoma tissues and 18 paracancerous tissues were measured by reverse transcriptionpolymerase chain reaction (RT-PCR) combined with silver staining technique. The expression of Livin, P53 and Bcl-2 proteins were detected by immunohistochemical method (streptavidin-peroxidase). Results RT-PCR results: Livin mRNA positive expression of esophageal carcinoma tissues was more evident than that of paracancerous tissues, the expression of both variants was simultaneous basically. Immunohistochemical results: the Livin protein positive expression rate of esophageal carcinoma tissues was higher evidently than that of paracancerous tissues(Plt;0.01). Livin protein positive expression rate of external coat of esophagus invaded by carcinoma was higher than that of tunica muscularis esophagi invaded by carcinoma(Plt;0.05); Livin protein positive expression rate of lymph node metastasis was higher than that of normal lymph node (Plt;0.05). The expression of Livin protein was not related to the expression of P53 protein（χ2=1.00,P=0.505）,but it was positively related to the expression of Bcl-2 protein（χ2=10.60，P=0.003）. Conclusion Aberrant expression of Livin may be a new target for diagnosis and gene treatment of esophageal carcinoma.The aberrant expression of Livinand apoptosis related gene Bcl-2 may play synergetic roles in process of carcinogenesis of esophageal carcinoma.
ObjectiveTo evaluate the efficacy and safety of robot-assisted thoracoscopic esophagectomy in the treatment of esophageal carcinoma. MethodsWe retrospectively analyzed the clinical data of 79 patients with robotassisted thoracoscopic esophagectomy in our hospital from August 2010 to June 2015. There were 43 males and 36 females at average age of 62 years. The clinical effect was analyzed. ResultsThe mean operation time was 245 min (range 170 min to 330 min). The mean blood loss was 75 ml (range 20 ml to 310 ml). The mean hospital stay was 10.2 days (range 7 days to 26 days). Two perioperative deaths occurred. A total of 14 (17.7%) patients with complication were reported. Mean lymph node harvest was 20.7 nodes with 10.9 in chest, 9.6 in abdomen. ConclusionRobot-assisted thoracoscopic esophagectomy is technically feasible and safe. It is expected to reduce surgical trauma and reduce the incidence of pulmonary complications.
ObjectiveTo detect human papilloma virus (HPV)infection with fluorescent quantitative real-time polymerase chain reaction (FQ-PCR)in Minnan population, and explore the correlation between HPV infection and carcinogenesis of esophageal carcinoma (EC)of Minnan patients. MethodsFQ-PCR was performed to examine HPV-6, HPV-11, HPV-16 and HPV-18 in 100 healthy Minnan people (healthy group, 66 males and 34 females with their age of 52.35±6.72 years)and 100 Minnan patients with squamous EC (EC group and tumor-adjacent normal tissue group, 64 males and 36 females with their age of 51.62±6.37 years)between October 2009 and December 2012. ResultsThe incidences of HPV infection in 100 EC tissues, 100 tumor-adjacent normal tissues and 100 esophageal mucosa tissues of healthy people were 22/100, 8/100 and 6/100 respectively, which were statistically different (χ2=10.63, P < 0.01). Positive infection of HPV-6, HPV-11, HPV-16 and HPV-18 was observed in 11 cases, 11 cases, 14 cases and 15 cases in EC group respectively, 5 cases, 6 cases, 7 cases and 8 cases in tumor-adjacent normal tissue group respectively, and 5 cases, 5 cases, 6 cases and 6 cases in the healthy group respectively (P > 0.05). Positive HPV infection was observed in 1 patients with well differentiated squamous EC, 21 patients with moderately differentiated squamous EC and 5 patients with poorly differentiated squamous EC (P > 0.05). ConclusionHPV infection may exist in tumor tissue of Minnan patients with squamous EC, and may be correlated with carcinogenesis and development of squamous EC.
ObjectiveTo summarize the clinical experience of thoracoscopic and laparoscopic esophagectomy for esophageal carcinoma. MethodWe retrospectively analyzed the clinical data of 38 patients with esophageal carcinoma undergoing thoracoscopic and laparoscopic esophagectomy in Central Hospital of Chongqing Three Gorges between March 2011 and March 2013. There were 25 males and 13 females aged 64.25±7.68 years (ranged 45-79 years). The esophagus was freed and the lymph nodes were cleaned under the thoracoscope in the left lateral position. Then the stomach was freed under laparoscope and lifted up to anastomose with the esophagus through the passageway behind the sternal bone. ResultsAll surgical process progressed successfully without intraoperative death or major hemorrhage. The total operating time ranged from 250 to 340 minutes. The intraoperative hemorrhage ranged from 80 to 350 ml. The number of lymph nodes cleaned ranged from 7 to 15 (10.24±2.04) and a total of 8 patients were found of tumor metastasis. Postoperative stage grading indicated 8 patients of T1N0M0, 16 patients of T2N0M0, 5 patients of T2N1M0, 6 patients of T3N0M0 and 3 patients of T3N1M0. Postoperative complications included chylothorax in 1 patient, pulmonary infection in 4 patients, and cervical anastomotic leakage in 4 patients. All 38 patients were followed up for 3 to 12 (6.31±2.18) months, and 1 patient was lost. Two patients died from cervical anastomotic leakage resulting in chest infection. The other all achieved recoveries without metastatic or recurrence of tumor. ConclusionThe intraoperative and postoperative complications of thoracoscopic and laparoscopic esophagectomy for esophageal carcinoma are less frequently than traditional surgery, so it's worthy of promotion in large regional general hospitals.
Abstract: Objective To study the expression of E-selectin on vascular endothelial cells of nude mice liver induced by esophageal carcinoma cells, in order to find out the function of E-selectin in the metastasis of esophageal carcinoma into the liver. Methods Twelve Balb/c nude mice aged from 6 to 8 weeks with their weight ranged between 20 and 25 grams were selected in our research. The mice were equally distributed into the experimental group and the control group(n=6). EC9706 cell solution (5×10.6/0.02 ml) were injected beneath the splenic capsule of the mice in the experimental group. One hour later, spleen was removed. For the mice in the control group, after laparotomy, phosphate buffer without EC 9706 was injected beneath the splenic capsule and spleen was also removed one hour after the injection. Eight hour later, we resected the liver of the nude mice, and expression of E-selectin on vascular endothelial cells of the liver was detected with reverse transcription polymerase chain reaction (RT-PCR) and immunohistochemistry (IHC). Results In the experimental group, 8 hours after injection of EC9706 cells (5×10.6), the results of RT-PCR showed expression of E-selectin mRNA in the liver, and IHC showed a positive protein expression of E-selectin in the cytosol and membrane of hepatic sinus vessels.However, no E-selectin mRNA expression was found in the control group and IHC showed a negative protein expression of E-selectin. Conclusion Human esophageal carcinoma cell line EC9706 can induce balb/c mice liver vascular endothelial cell E-selectin expression, which shows that EC9706 may stay in the liver and form etastatic focus.
ObjectiveTo compare medical cost and utilization efficiency of medical resources between manual layered anastomosis with mechanical stapling technique in esophagectomy. MethodsClinical data of 132 patients who underwent surgical resection of esophageal carcinoma in the Department of Thoracic Surgery of Gansu Tumor Hospital between January and October 2011 were respectively analyzed. According to different anastomotic techniques, all the patients were divided into a manual layered anastomosis group (including 40 males and 20 females with their age of 36-72 (49.3±7.6) years) and a mechanical stapling technique group (including 50 males and 22 females with their age of 30-79 (51.0±8.6) years). Demographic data, operation data, postoperative complications, direct and indirect medical cost, and constitution of direct medical cost were compared between the 2 groups. ResultsMedical cost of esophagectomy was 14 505.03± 1 523.37 yuan in the manual layered anastomosis group and 19 891.05±1 634.58 yuan in the mechanical stapling technique group respectively, which were statistically different (P < 0.05). Material cost was 2 242.00±751.08 yuan in the manual layered anastomosis group and 5 424.00±1 876.22 yuan in the mechanical stapling technique group respectively, which were statistically different (P < 0.05). Cost-effectiveness analysis showed that cost-effectiveness ratio in the manual layered anastomosis group was lower, thus this anastomotic technique was more reasonable. ConclusionMedical cost of manual layered anastomosis is lower than that of mechanical stapling technique in esophagectomy, as the utilization efficiency of medical resources of manual layered anastomosis is higher than that of mechanical stapling technique.
