Superior mesenteric artery exposure: The SMA is a critical vascular structure, and the Kocher manoeuvre exposes its supramesenteric segment. This exposure is valuable for identifying and managing aberrant vessels, such as the right hepatic artery arising from the SMA. [1] Control of portal vein in hemorrhage:
SMA syndrome is also known as Wilkie's syndrome, cast syndrome, mesenteric root syndrome, chronic duodenal ileus and intermittent arterio-mesenteric occlusion. [3] It is distinct from nutcracker syndrome , which is the entrapment of the left renal vein between the AA and the SMA, although it is possible to be diagnosed with both conditions.
The duodenal switch (DS) procedure, also known as a gastric reduction duodenal switch (GRDS), is a weight loss surgery procedure that is composed of a restrictive and a malabsorptive aspect. The restrictive portion of the surgery involves removing approximately 70% of the stomach (along the greater curvature) and most of the duodenum .
In anatomy, the gastroduodenal artery is a small blood vessel in the abdomen. It supplies blood directly to the pylorus (distal part of the stomach ) and proximal part of the duodenum . It also indirectly supplies the pancreatic head (via the anterior and posterior superior pancreaticoduodenal arteries ).
Duodenal atresia is the congenital absence or complete closure of a portion of the lumen of the duodenum. It causes increased levels of amniotic fluid during pregnancy ( polyhydramnios ) and intestinal obstruction in newborn babies.
The goals of surgery are to remove any dead tissue and close the hole in the gastrointestinal wall. Peritoneal wash is performed and a drain may be placed to control any fluid collections that may form. [22] A Graham patch may be used for duodenal perforations. [23]
By stretching the stomach, the dissection proceeds along the greater curvature toward the left medial duodenal wall, then toward the back wall, and finally toward the lateral duodenal wall of the superior part as far as the beginning of the hepatoduodenal ligament. [9] This way, 3 to 5 cm of the back wall of the duodenum can be exposed. [9]
Billroth I, more formally Billroth's operation I, is an operation in which the pylorus is removed and the distal stomach is anastomosed directly to the duodenum. [1] [2] The operation is most closely associated with Theodor Billroth, but was first described by Polish surgeon Ludwik Rydygier. [2] The surgical procedure is called a ...
