Gastric emptying time is regarded as delayed if it is 5 hours or longer and is defined as the time required for the capsule to reach the duodenum, as determined by a pH increase of more than 3 units.

A gastric emptying scintigraphy test involves eating a bland meal that contains a small amount of radioactive material. An external camera scans the abdomen to locate the radioactive material.

Patients who take glucagon-like peptide 1 (GLP-1) receptor agonists may be at increased risk of aspiration during anesthesia due to delayed gastric emptying, according to case reports. In 2023, the American Society of Anesthesiologists suggested holding the GLP-1 agonists on the day of the procedure/surgery or a week earlier. [30]
Three of the most common post-operative complications are delayed gastric emptying, bile leak, and pancreatic leak.

Portal hypertensive gastropathy can also be treated with endoscopic treatment delivered through a fibre-optic camera into the stomach. Argon plasma coagulation and electrocautery have both been used to stop bleeding from ectatic vessels, and to attempt to obliterate the vessels, but have limited utility if the disease is diffuse.

The first person to use a gastric balloon for the treatment of obesity was A. Henning 1979. (Inn. Med.6(1979),149) He and his wife used it in a self-experiment. The use of gastric filling devices to induce weight loss is not new. DeBakey's review in 1938 showed that bezoars led to weight loss. [25]
