	~~#redirect~~ [[~~Small_intestine#Small_bowel_obstruction~~]]		'''Small bowel obstruction''', abbreviated '''SBO''', is a common [[pathology]] managed by general surgeons.

			This article gives an overview of SBOs. Its primary focus is benign causes of SBO that have nonspecific pathologic findings. Specific causes definitively identified by pathology, e.g. [[adenocarcinoma]], are dealt with separately.

			==General==
			*Radiologic/[[clinical diagnosis]].

			The usual causes of bowel obstruction (large & small) are (mnemonic) ''SHAVING'':
			*Strictures (think [[IBD]]).
			*Hernias.
			*Adhesions.
			*[[Volvulus]].
			*Intussusception.
			*Neoplasia.
			*Gallstone ileus.

			The top three are:<ref>URL: [http://www.emedicine.com/EMERG/topic66.htm http://www.emedicine.com/EMERG/topic66.htm]. Accessed on: 19 April 2011.</ref><ref>{{Ref TN2007 \|GS21}}</ref>
			* Adhesions > hernias > neoplasms.

			In the context of bowel obstructions and IBD, pathologists often see resected [[stoma]]s (that were put in place emergently). These specimens are usually fairly straight forward.

			==Radiology==
			*Air-fluid levels.

			==Gross==
			*+/-Adhesions.
			*+/-Bowel contorted.
			*+/-Luminal narrowing +/-proximal dilation.
			*+/-Serosal exudate.
			**Suggestive of perforation.

			==Microscopic==
			Features:
			*+/-Adhesions (serosal).
			**Dense fibrous tissue replaces the adipose tissue.
			**+/-Increased vascularity.
			*+/-Submucosal fibrosis.
			*+/-[[Serositis]] - seen in small bowel perforation.
			*+/-Foreign body-type granuloma - due to previous surgical intervention.

			DDx:
			*Small bowel [[adenocarcinoma]] - most important differential diagnosis.
			*Metastatic adenocarcinoma - classically on the serosal aspect.
			*[[Signet ring cell carcinoma]].
