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]
A gastric emptying study is a nuclear medicine study which provides an assessment of the stomach's ability to empty. It may be used if there are complications after gastric surgery, for gastric reflux , or suspected gastroparesis amongst other indications. [ 1 ]
This condition is also called rapid gastric emptying. [1] It is mostly associated with conditions following gastric or esophageal surgery, though it can also arise secondary to diabetes or to the use of certain medications; it is caused by an absent or insufficiently functioning pyloric sphincter, the valve between the stomach and the duodenum.

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.
Gastric bypass surgery refers to a technique in which the stomach is divided into a small upper pouch and a much larger lower "remnant" pouch, where the small intestine is rearranged to connect to both. Surgeons have developed several different ways to reconnect the intestine, thus leading to several different gastric bypass procedures (GBP ...
The SADI-S is a single anastomosis bariatric surgery. It is different from the classic duodenal switch, the gastric bypass (RNY) or sleeve gastrectomy.It is a type of bariatric surgery carried out to lose weight and to mitigate various metabolic issues including type 2 diabetes, dislipidemia, metabolic syndrome, and polycystic ovary syndrome.
This device fits over a therapeutic double-channel endoscope to create a sutured row of stomach tissue. The tissue helix is advanced from the endoscope, put up against stomach tissue, and turned 2-4 rotations to access the gastric muscle layer. The helix is then retracted towards the scope, bringing the full-thickness acquired stomach tissue ...
Jejunoileal bypass (JIB) was a surgical weight-loss procedure performed for the relief of morbid obesity from the 1950s through the 1970s in which all but 30 cm (12 in) to 45 cm (18 in) of the small bowel were detached and set to the side.
