What is gastroduodenostomy ?
A gastroduodenostomy is a surgical procedure that involves the creation of a new connection between the stomach and the duodenum, the first section of the human small intestine. This section is the smallest, but it is where chemical digestion—a step vital to the digestive and metabolic process—occurs.
This procedure is often recommended for patients suffering from stomach cancer, peptic ulcers, gastric obstruction, and a malfunctioning pyloric valve. There are two types of gastroduodenostomy:
- Billroth I. This technique is performed after a gastrectomy, or the complete or partial removal of the stomach. A Billroth I procedure restores normal gastrointestinal physiology and preserves the duodenal passage. This procedure is often recommended for patients with benign diseases in the gastrointestinal system.
- Billroth II. This procedure involves the creation of a connection between the stomach and the jejunum, another section of the small intestine. A Billroth II procedure is recommended for patients unsuited for a Billroth I. This involves fewer modifications to biliary and pancreatic functions, and has shown to decrease the occurrence of stomach inflammation and ulceration.
