Abstract: Objective To evaluate the effect on gastroesophageal reflux and gastric emptying in the different route of gastroesophageal anastomosis objectively after esophagectomy for patients with midesophageal carcinoma. Methods Forty patients with midesophageal carcinoma were randomly divided into two groups. Esophageal bed group (n=20): the gastroesophageal anastomosis were performed while the stomach were pulled on through the esophageal bed after esophagectomy; endothoracic group (n=20): gastroesophageal anastomosis were performed while the stomach were pulled on in the thoracic cavity. Ten persons had no disease of digestive system and healthy volunteers were recruited as normal control group. 24-hour esophageal pH monitoring and radioisotope gastric emptying checkup were carried out in all experimental subjects 3 months after operation, so as to observe the changes of gastroesophageal reflux and gastric emptying. Results All of the patients’s operation were success. And no anastomotic leakage and no anastomotic stenosis. Three months after operation, the patients in both operation groups were with different level of reflux. DeMeester total appraise score, the times of regurgitation of gastric juice in 24h, gt;5 min reflux frequency, the longest time of keep reflux, pHlt;4.00 total time and pHlt;4.00 of total time percent, these targets in both operation groups were higher than those in control group (Plt;0.01) DeMeester total appraise score, the times of regurgitation of gastric juice in 24 hours, the longest time of keeping reflux, pHlt;4.00 of total time and pHlt;4.00 of total time percent in esophageal bed group were lower than those in endothoracic group(Plt;0.01). The recent period of gastric emptying percentage (GE) in both operative groups were lower than that in normal control group. GE in esophageal bed group experimental meal in the stomach after entering the 30,60,90,120,180 and 240 min were higher than those in endothoracic group. Conclusion After the operation of esophagogastric anastomosis through esophageal bed in upper aortic site,gastroesophageal reflux and delayed gastric emptying exist objectively, However, the technique is superior to the traditional technique to reduce the extent of gastroesophageal reflux and delayed gastric emptying, its mechanism might be the result of mechanical factors.
Objective To explore clinical application values of thoracoscopic and laparoscopic-assisted minimally invasive McKeown procedure for esophageal cancer. Methods Clinical data of 196 patients with esophageal cancer （EC） who underwent thoracoscopic and laparoscopic-assisted minimally invasive McKeown procedure in West China Hospital of Sichuan University from February 2008 to August 2012 were analyzed retrospectively. There were 145 male and 51 female patients with their age of 40-76 （58.8±6.6） years. There were 43 patients with EC in the upper segment of the esophagus, 115 patients with EC in the middle segment of the esophagus and 38 patients with EC in the lower segment of the esophagus.Results Total operation time was 215-780 （305.0±40.7） minutes，including thoracoscopic operation time of 50-580 （105.0±38.4） minutes and laparoscopic operation time of 28-105 （54.0±8.6） minutes. Intraoperative blood loss was 20-440 （285.4±38.5） ml. The number of dissected lymph nodes was 6-39 （20.4±1.6） for each patient. Postoperative hospital stay was 7-93 （12.8±5.2） days. Sixty patients （30.6%） had postoperative complications，including 28 patients （14.3%） with pulmonary comp-lications，5 patients （2.5%） with chylothorax，5 patients （2.5%） with arrhythmias，15 patients （7.6%） with anastomotic fistula，10 patients （5.0%） with recurrent laryngeal nerve injury，and other complications in 2 patients. Conclusion Thoracoscopic and laparoscopic-assisted minimally invasive McKeown procedure is a safe and feasible operation for esophageal cancer.
摘要:目的: 探討自發性食管破裂的診斷和治療經驗。 方法 :對我院1996年2月至2009年8月收治的8例自發性食管破裂患者的診斷和治療作回顧性分析。 結果 :全組患者7例行手術治療,1例行保守治療。6例患者行修補手術,其中4例行分層縫合,2例行全層縫合。1例行食管切除胃食管吻合術。本組痊愈7例,死亡1例。 結論 :早期診斷和早期治療是自發性食管破裂的治療原則。確診患者,若病情允許,應首選手術治療。Abstract: Objective: To explore the clinical diagnosis and treatment of spontaneous esophageal rupture. Methods :The clinical features, diagnosis and surgical treatment of 8 patients with spontaneous esophageal rupture were retrospectively reviewed. Results :There were 7 cases treated by surgical therapy and 1 case for conservative treatment. 6 cases were treated by surgical repair including 4 cases of layered suture and 2 cases of singlelayer suture. 1 case was treated by esophagus resection and gastroesophagostomy. In the whole group, 7 cases were cured and 1 case died. Conclusion :The therapeutic principle of spontaneous esophageal rupture are early diagnosis and early treatment. For diagnosed patient, surgical procedure is the first choice if condition permitted.
Esophageal cancer is one of the common malignant tumors with high incidence and poor prognosis. Angiogenesis-related pathways play an important role in the occurrence and development of esophageal cancer. Vascular endothelial growth factor (VEGF) is the main mediator of angiogenesis. In addition to promoting angiogenesis and maintaining the survival of neovascularization, VEGF can also directly act on esophageal cancer cells and promote the occurrence and development of tumors. This article reviews the biology of VEGF and its effect on blood vessels, the expression of VEGF in esophageal cancer cells and its influencing factors, the role of VEGF in esophageal cancer cells, the immunomodulatory activity of VEGF and the clinical study of VEGF inhibitors. The purpose of this study is to provide a basis for more rational use of VEGF inhibitors in the treatment of esophageal cancer.
摘要:目的:探討晚期食管癌切除、縱隔淋巴結清掃及術中縱隔熱灌注化療對殘留于氣管、支氣管、胸主動脈、奇靜脈等器官的癌性肉眼微小病灶治療效果。方法:選擇食管癌病變浸潤超過外膜層外侵至氣管、支氣管、胸主動脈、奇靜脈等器官患者112例，隨機分為兩組:治療組56例,術中42～43℃無菌蒸餾水2000～2500 mL加入順鉑(DDP)150 mg及氟尿嘧啶(5FU)1200 mg在體外循環下行縱隔熱灌注化療40 min;對照組56例,術中未進行縱隔熱灌注化療。結果:治療組術后第一年有6例出現縱隔區域腫瘤復發及淋巴結轉移,術后第二年有11例縱隔區域腫瘤復發及淋巴結轉移;對照組術后第一年有14例出現縱隔區域腫瘤復發及淋巴結轉移,術后第二年23例出現縱隔區域腫瘤復發及淋巴結轉移。結論:晚期食管癌術中縱隔熱灌注化療可明顯減少或延遲縱隔區域腫瘤復發及淋巴轉移,提高術后第一至第二年生存率。Abstract: Objective: To explore the advanced esophageal cancer resection, mediastinum, lymph node dissection, mediastinum, hot infusion chemoembolization and clinical observation of residual heat infusion chemoembolization and trachea, or the thoracic aorta, bronchus, eye cancer organs such as intravenous of tiny lesions therapeutic effect. Methods: Select esophageal lesions than the outer membrane layer of infiltrating the trachea and bronchus to the thoracic aorta, and 112 cases of patients with venous organs such as random points to two groups: treatment group treated with perfusion of 56 cases at 4243 degrees Celsius sterile 2000 mL distilled water 2500 mL ~ (DDP) joined cisplatin 150 mg, 5fluorouracil (5FU 1200 mg) in extracorporeal circulation downlink mediastinal hot perfusion 40 minutes, control group treated with perfusion of 56 cases without mediastinal hot perfusion chemotherapy. Results: Treatment group in 6 cases occured after first mediastinal tumor recurrence and regional lymph node metastases after 11 cases, the regional recurrence and lymphatic metastasis mediastinal, control group first fill after 14 cases mediastinal tumor recurrence and bureau of regional lymph node metastasis appeared in 23 cases, surgery between regional tumor locally recurrent lymph node metastases. Conclusion: Advanced esophageal intraoperative mediastinal hot perfusion chemotherapy can obviously reduce or delay mediastinal tumor recurrence and regional lymph node metastases, raise the firstsurial.
