Duodenal bulb
Interior of the stomach. (There is no label for "Duodenal bulb", but the portion of the duodenum labeled at upper left is the duodenal bulb.)
Latin	pars superior duodeni, bulbus duodeni
Gray's	subject #248 1169

The duodenal bulb is the portion of the duodenum which is closest to the stomach. It normally has a length of about 5 centimeters. The duodenal bulb begins at the pylorus and ends at the neck of the gallbladder. It is located posterior to the liver and the gallbladder, and superior to the pancreatic head. The gastroduodenal artery, portal vein, and common bile duct lie just behind it. The distal part of the bulb is located retroperitoneally. It abuts the Pyloric sphincter.

The duodenal bulb is the place where duodenal ulcers occur. Duodenal ulcers are more common than gastric ulcers and, unlike gastric ulcers, are caused by increased gastric acid secretion. Duodenal ulcers are commonly located anteriorly, and rarely posteriorly. Anterior ulcers can be complicated by perforation, while the posterior ones bleed. The reason for that is explained by their location. The peritoneal or abdominal cavity is located anterior to the duodenum. Therefore, if the ulcer grows deep enough, it will perforate; whereas if a posterior ulcer grows deep enough, it will perforate the gastroduodenal artery and bleed.

• BACKGROUND AND AIM: Endoscopic submucosal dissection (ESD) enables complete, collective removal of gastrointestinal (GI) malignant tumors, but requires a long operation time. Air insufflated during ESD is distributed throughout the entire GI tract, and thus causes an enlarged feeling of the abdomen.
