Stenosis of the gastrojejunal anastomosis is a recognized complication. The pathophysiological mechanisms involved in the formation of stenosis are not well known. Gastrojejunal strictures can be classified based on time of onset, mechanism of formation, and endoscopic aspect. Diagnosis is usually obtained by endoscopy. The two main treatment alternatives for stomal stricture are: endoscopic dilatation (balloon or bouginage) and surgical revision (open or laparoscopic). Both techniques of dilation [through-the-scope (TTS) balloon dilators, Bougienage dilators] are considered safe, effective, and do not require hospitalization. The optimal technique for dilation of stomal strictures remains to be determined, but many authors prefer the use of TTS balloon catheters. Most patients can be successfully treated with 1 or 2 sessions. The need for reconstructive surgery of a stomal stricture is extremely rare.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

The objective of this study was to evaluate the different types of GBP in treatment of type 2 diabetes. Methods Patients with type 2 diabetes were randomly divided into two groups: those who underwent gastrojejunal loop anastomosis bypass and those who underwent gastrojejunal Roux-en-Y bypass. Blood glucose alterations, operation time, and operation complications were observed. Results Gastrojejunal loop anastomosis bypass and gastrojejunal Roux-en-Y bypass were both effective in the treatment of selected patients with type 2 diabetes. Compared with gastrojejunal Roux-en-Y bypass, gastrojejunal loop anastomosis bypass had the advantages of easier implementation, shorter operation time, and fewer operation complications. Conclusions Gastrojejunal loop anastomosis is effective in treatment of type 2 diabetes. It is safe, easy to implement, and worthy of clinical popularization.展开更多
