	~~#REDIRECT~~[[SMA syndrome]]		==Background==
			*AKA: Wilke's syndrome
			*Rare condition, first described by Von Rokitansky in 1861 and then further studied in detail by Wilke in 1912
			*Occurs when duodenum is compressed between aorta and superior mesenteric artery
			*Can lead to gastrointestinal obstruction at level of duodenum
			**Chronic, intermittent, or acute
			**Partial or complete
			*Controversy over this diagnosis

			===Etiology===
			*SMA takes off from the abdominal aorta at about 45 degree angle, due to cushioning from fatty/lymphatic tissue called mesenteric pad
			*Third part of the duodenum courses between the angle formed
			*Narrowing of this angle can cause entrap and compress of the duodenum
			*Factors that narrow this angle include:
			**Significant weight loss (most common cause)
			*Corrective spinal surgery for scoliosis lengthens the spine
			**Congenital defects, suggested genetic predisposition
			**Abdominal adhesions

			==Clinical Features==
			*Early satiety, belching, post-prandial bloating, weight loss
			*[[Nausea and vomiting]], can be bilious
			*[[Abdominal pain]], mid-abdomen, may be improved with changes of position
			*Proximal [[small bowel obstruction]]

			==Differential Diagnosis==
			*See [[Abdominal Pain]]
			*See [[Nausea and vomiting]]

			==Evaluation==
			*Evaluate for alternative causes of symptoms and for complications
			*Suspected based on signs and symptoms
			*Diagnosis confirmed by imaging:
			**Upper GI series
			**Upper endoscopy
			**CT

			==Management==
			*Correct [[dehydration]], [[electrolyte abnormalities]], [[malnutrition]]
			*Primary goal is to correct the underlying cause, typically regain lost weight
			*Acute management:
			**Adjusting body position to alleviate symptoms, such as knee to chest or lying on left side
			**[[Nasogastric tube]] for decompression
			*Some patients may require a feeding tube distal to the obstruction or parenteral nutrition
			*Surgery sometimes indicated
			**Strong's procedure: duodenum moved to the right of the SMA
			**Gastrojejunostomy, duodenojejunostomy

			==Disposition==
			*Depends on clinical presentation
			*If complete obstruction, admission for decompression and nutrition
			*Outcome excellent with early diagnosis and appropriate treatment
