The Roux-en-Y laparoscopic gastric bypass, first performed and reported on in case studies between 1993 and 1994, [3] is regarded as one of the most difficult procedures to perform by limited access techniques.
The esophageal branch of the left gastric vein drains into the azygos vein. In cases of portal hypertension, this communication allows for blood to bypass the portal vein and reach systemic circulation.
The right gastric vein passes right along the lesser curvature of the stomach to the pylorus. [1] [2] Once there, it joins onto the portal vein before the duodenum.[1] [2] The prepyloric vein is the last connecting branch onto the right gastric vein, marking the end of the stomach, and draining the proximal part of the duodenum.
There are dozens of conditions that may require tube feeding (enteral nutrition) to prevent or treat malnutrition. Conditions that necessitate feeding tubes include prematurity, failure to thrive (or malnutrition), neurologic and neuromuscular disorders, inability to swallow, anatomical and post-surgical malformations of the mouth and esophagus, cancer, Sanfilippo syndrome, and digestive ...
The short gastric arteries form anastomoses with branches of the left gastric artery, and left gastroepiploic artery. [1]Unlike the gastroepiploics and the left and right gastric arteries, the short gastric arteries have poor anastomoses if the splenic artery is blocked.
A Sengstaken–Blakemore tube is a medical device inserted through the nose or mouth and used occasionally in the management of upper gastrointestinal hemorrhage due to esophageal varices (distended and fragile veins in the esophageal wall, usually a result of cirrhosis).
Sleeve gastrectomy or vertical sleeve gastrectomy, is a surgical weight-loss procedure, typically performed laparoscopically, in which approximately 75 - 85% of the stomach is removed, [1] [2] along the greater curvature, [3] which leaves a cylindrical, or "sleeve"-shaped stomach the size of a banana.
Origin. In most (53%) individuals, the RGA arises from the proper hepatic artery. It can also arise from the region of division of the common hepatic artery (20%), the left branch of the hepatic artery (15%), the gastroduodenal artery (8%), and - most rarely - the common hepatic artery itself (4%).
