Combined restrictive and malabsorptive techniques are called gastric bypass techniques, of which Roux-en-Y gastric bypass surgery (RGB) is the most common. In this technique, staples are used to form a pouch that is connected to the small intestine, bypassing the lower stomach, the duodenum, and the first portion of the jejunum.
A person may need surgery if dumping syndrome is caused by previous gastric surgery or if the condition is not responsive to other treatments. For most people, the type of surgery depends on the type of gastric surgery performed previously. However, surgery to correct dumping syndrome often has unsuccessful results. [1]
Billroth II, more formally Billroth's operation II, is an operation in which a partial gastrectomy (removal of the stomach) is performed and the cut end of the stomach is closed. The greater curvature of the stomach (not involved with the previous closure of the stomach) is then connected to the first part of the jejunum in end-to-side anastomosis.
Three of the most common post-operative complications are delayed gastric emptying, bile leak, and pancreatic leak. Delayed gastric emptying, normally defined as an inability to tolerate a regular diet by the end of the first post-op week and the requirement for nasogastric tube placement, occurs in approximately 17% of operations.
Dumping syndrome (rapid emptying of undigested stomach contents) is another common complication of bariatric surgery, especially after Roux-en-Y, which is further classified into early and late dumping syndrome. [48] Dumping syndrome in some cases may be associated with more efficient weight loss, however, it can be uncomfortable. [48]

Because stomach emptying is the testing process's rate-limiting step, the amount of 13CO2 present in an exhaled breath test represents gastric emptying. Every 30 minutes, post-meal breath samples are collected and analyzed using isotope-ratio mass spectrometry. For a total of 4–6 hours, samples are collected every 30 minutes. [39]
