A perforated ulcer is a condition in which an untreated ulcer has burned through the mucosal wall in a segment of the gastrointestinal tract (e.g., the stomach or colon) allowing gastric contents to leak into the abdominal cavity.
Duodenal causes: Duodenal ulcer; Vascular malformation, including aorto-enteric fistulae. Fistulae are usually secondary to prior vascular surgery and usually occur at the proximal anastomosis at the third or fourth portion of the duodenum where it is retroperitoneal and near the aorta.

A peptic ulcer is a defect in the inner lining of the stomach or duodenum typically due to excessive stomach acid. Extension of the ulcer through the lining of the digestive tract results in spillage of the stomach or intestinal contents into the abdominal cavity, leading to an acute chemical peritonitis.

The gastroduodenal artery can be the source of a significant gastrointestinal bleed, which may arise as a complication of peptic ulcer disease.Because of its close relationship to the posteromedial wall of the second part of the duodenum, deeply penetrating ulcers or tumours of the duodenum may cause torrential bleeding from the gastroduodenal ‘artery of haemorrhage'.

Dieulafoy's lesion (French:) is a medical condition characterized by a large tortuous artery [2] most commonly in the stomach wall that erodes and bleeds. It can present in any part of the gastrointestinal tract. [3] It can cause gastric hemorrhage [4] but is relatively uncommon.
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.
The duodenal bulb is the site of duodenal ulcer occurrence. 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.
Types of mesenteric ischemia are generally separated into acute and chronic processes, because this helps determine treatment and prognosis. [ 3 ] Bowel obstruction is most often caused by intestinal adhesions , which frequently form after abdominal surgeries, or by chronic infections such as diverticulitis , hepatitis , and inflammatory bowel ...
