Surgical treatment effects in cancer of the cardia and esophagogastric junction

Objective: To evaluate the treatment effects of total gastrectomy (TG) and proximal gastrectomy (PG) for cancer of the cardia and esophagogastric junction. Methods: forty-five patients with cancer of the cardia and esophagogastric junc- tion underwent surgical resection. Of them, 29 were treated using proximal gastrectomy and 16 total gastrectomy. The 3-year and 5-year survival rate and the postoperative complication rate and mortality rate were followed up and compared between the two groups. Results: The 3-year and 5-year survival rates of group PG were 44.8% and 20.7%, of group TG were 37.5% and 18.8%, respectively, and the differences were not statistically significant (χ2 = 3.84, P > 0.05; χ2 = 3.89, P > 0.05). The postoperative complication and mortality rate of group PG were 13.7% and 6.8%, of group TG was all 6%, respectively. Conclusion: Proximal and total gastrectomy treatment effects can not significantly influence the prognosis of patients in progressive stage of cancer of cardia and esophagogastric junction.

Intensify standardized therapy for esophageal and stomach cancer in tumor hospitals

Covered nitinol stents for the treatment of esophageal strictures and leaks

AIM:To compare 2 different types of covered esophageal nitinol stents(Ultraflex and Choostent) in terms of efficacy,complications,and long-term outcome.METHODS:A retrospective review of a consecutive series of 65 patients who underwent endoscopic placement of an Ultraflex stent(n = 33) or a Choostent(n = 32) from June 2001 to October 2009 was conducted.RESULTS:Stent placement was successful in all patients without hospital mortality.No significant differences in patient discomfort and complications were observed between the Ultraflex stent and Choostent groups.The median follow-up time was 6 mo(interquartile range 3-16 mo).Endoscopic reintervention was required in 9 patients(14%) because of stent migration or food obstruction.No significant difference in the rate of reintervention between the 2 groups was observed(P = 0.8).The mean dysphagia score 1 mo after stent placement was 1.9 ± 0.3 for the Ultraflex stent and 2.1 ± 0.4 for the Choostent(P = 0.6).At 1-mo follow-up endoscopy,the cover membrane of the stent appeared to be damaged more frequently in the Choostent group(P = 0.34).Removal of the Choostent was possible up to 8 wk without difficulty.CONCLUSION:Ultraflex and Choostent proved to be equally reliable for palliation of dysphagia and leaks.Removal of the Choostent was easy and safe under mild sedation.

Recent advances in the surgical treatment of pancreatic cancer

INTRODUCTIONPancreatic cancer remains the fourth commonest cause of cancer related death in the western world[1]. The prognosis remains dismal due partly to late presentation, with associated low resectability rates, and the aggressive biological nature of these tumors. The median survival time from diagnosis in unresectable tumors remains only 4 6 months.For those patients amenable to surgical resection over the last 20 years have seen marked improvements in postoperative mortality and morbidity, especially in specialist pancreatic centres 23. Despite these changes long-term survival remains low. with a total 5-year survival rate remaining less than 5%.Patients with ampullary cancer have a better 5-year survival of 40°%-60°%.

Is surgical treatment of cancer of the gastric cardia or esophagus associated with a concurrent major pulmonary operation feasible？One center＇s experience

Background Pulmonary complications are a major cause of mortality after operation for cancer of the gastric cardia or esophagus.Although the risk involved in gastric cardiectomy or esophagectomy associated with a concurrent major pulmonary operation is expected to be much higher,it has seldom been evaluated on the basis of clinical experience.The aim of this study was to investigate the possibility and feasibility of the gastric cardiectomy or esophagectomy associated with a major pulmonary operation.Methods From August 2003 to January 2011,14 patients underwent concurrent gastric cardiectomy or esophagectomy and a major pulmonary operation in our hospital.This included eight for pulmonary invasion of esophageal carcinoma,and six for synchronous lung tumor.All patients underwent systematic lymph node dissection for cardiac or esophageal cancer.To prevent postoperative complications,the operative approach and dissection procedures for cardiac or esophageal carcinoma were modified according to the associated pulmonary operation and the extent of cancer invasion.All thoracotomies for cardiectomy or esophagectomy were performed on the same side as the major pulmonary operation.Results All patients underwent a curative operation.There were no deaths or postoperative complications in the six synchronous lung tumor patients.In the eight pulmonary invasion patients,one patient died of respiratory failure 11 days after operation,and postoperative complications developed in four of them,but none was fatal.Six patients were still alive.Conclusions Curative gastric cardiectomy or esophagectomy associated with concurrent major pulmonary operation is not contraindicated in patients in good condition.In selected patients,when the operative procedures for cardiectomy or esophagectomy are appropriately modified to minimize the effect of the associated pulmonary operation,the treatment is associated with a low operative morbidity and mortality with an acceptable long-term survival.
