Databases and references were searched for all randomizedcontrolled trials and comparative clinical studies that compared LS with HS esophagogastric anastomosis for esophageal cancer. The primary outcomes compared were anastomotic leak and stricture. Subgroup analyses were performed according to site of anastomosis.RESULTS: Fifteen studies were used, comprising 3203 patients(n = 2027 LS and 1176 HS). Primary outcome analysis revealed a significant decrease in anastomotic leakage(RR = 0.51, 95%CI: 0.41-0.65; P < 0.00001) a s s o c i a t e d w i t h L S a n a s t o m o s i s. A s i g n i f i c a n t l y reduced rate of anastomotic stricture associated with LS was also found(RR = 0.56, 95%CI: 0.49-0.64; P < 0.00001). A subgroup analysis according to the site of anastomosis revealed a significantly reduced rate of anastomotic stricture(P < 0.00001). Although there was no significant difference in the decrease in thoracic anastomotic leakage, there was a significant decrease in cervical anastomotic leakage associated with LS(P < 0.00001).CONCLUSION: This meta-analysis indicates that the LS technique contributes to a reduced rate of leakage and stricture compared with the HS method.展开更多

All data are registered prospectively in cooperation with the Institute of Quality Assurance in Surgery at Otto-von-Guericke University Magdeburg.?Methods: Data are collected in an online data bank. Data collection began in 2005 for the results of Roux-en-Y Gastric Bypass (RYGB). In addition to primary bariatric operations, data regarding the complications and the amelioration of comorbidities have been analyzed. Participation in the quality assurance study is required for all certified centers in Germany.?Results: Roux-en-Y Gastric Bypass is the most popular bariatric operation in Germany. There were 5115 operations performed from 2005 to 2010. A circular anastomosis was performed in 1587 patients, and a linear anastomosis was performed in 2734 patients. In 783 patients the hand-sewn technique was used. The leakage rate for the linear technique is 1.6%, and the leakage rate is 1.2% for circular anastomosis and 1.4% for hand-sewn technique. The overall postoperative complication rate was significantly higher using the circular technique than using the linear or hand-sewn approach.?Conclusion: RYGB is a popular procedure in Germany. The complication rate has decreased since 2005. A comparison of hand sewn versus linear and versus circular anastomosis indicated a higher complication rate in circular gastrojejunal junctions.展开更多
