Small Bowel • Duodenum • Jejunum • Ileum • Large Intestine • cecum
Small intestine The small intestine is the portion of the digestive system most responsible for absorption of nutrients from food into the bloodstream. The pyloric sphincter governs the passage of partly digested food from the stomach into the duodenum. This short first portion of the small intestine is followed by the jejunum and the ileum. The ileocecal valve of the ileum passes digested material into the large intestine.
Duodenojejunal flexure Superior (1st) part of duodenum Descending (2nd) part of duodenum Horizontal (3rd) part of duodenum SMA Ascending (4th) part of duodenum
Autopsy-7M • Life-4.5~5M • Duoodenum • Shortest,widest,25cm,c-shape • Jejunum • 2/5,coiled spring,feathery • Ileum • 3/5,smoother
8981608 Multiple diverticulum over jejunum
92008859 Diverticulum at the 2nd portions of the duodenum.
92031274 Duodenal diverticulum, second portion
3261344 Edematous change of mucosal fold & wall thickness; Partial obstruction over ileum Poor peristasis of small bowel, consistent with adhesion.
3261344 Obstruction-case 1
92018619 Obstruction-case 2 Disproportional dilatation of jejunum,suggest obstruction
92018619 The obstruction level should be around distal jejunum
20157972 Obstruction-case 3 NG placed in duodenum
There is extrinsic compression at distal third portion of duodenum ,probable due to vascular indentation
Multiple segmental narrowing with mucosal tethering of bowel loops and nodularity outline at ileum. Peritonea carcinomatosis is considered. The barium flow is partially obstructed,but still patent.
After 6 hours,the barium flow passed through the ileum into the right side colon. The opacified right side colon is dilatated with compression to the descending portion of duodenum at hepatic flexure
92028879 Obstruction-case 4 Disproportional dilatation of small intestine, suggestive of intestinal obstruction, more dilated proximal jejunum is found The obstructive level may be at proximal jejunum Collapsed distal bowel loops without opacification by barium
92020508 Smooth margin filling defect in the cecum. D/D cecal tumor or postappendectomy change
92118992 Mass effect-case 2 Soft tissue mass over LUQ area with mass effect to stomach and bowel loops noted
92009992 Mass effect-case 3 An ovoid filling defect within the lumen of the 2nd portion of the duodenum; c/w duodenal tumor.
92055736 Mass effect-case 4 .Diffuse dilated duodenum and proximal jejunum
92055736 Persistent, long segmental luminal narrowing at the proximal jejunum with "beak" appearance of the proximal small bowel, malignancy like jejunal Ca. is considered
92030704 Marked dilatation of small bowel loops (mainly are jejunum) with contrast medium stasis during the procedure. Intestinal partial obstruction at jejunum, r/o adhesion.
92030704 Fistula formation (vagina and ileum) at RLQ
20366598 A large intraluminal round filling defect in 2nd portion of the duodenum, R/O duodenal tumor or polyps. Multiple nodularities of the jejunum, highly suspecting multiple polyps.
6377989 Extravasation of the contrast material from duodenal bulb into a blind pouch in the right upper abdomen,perforation of duodenal bulb is considered Perforation in the duodenal bulb with a space of contrast pooling in the right upper abdomen.
6377989 Extravasation of the contrast material from duodenal bulb into a blind pouch in the right upper abdomen,perforation of duodenal bulb is considered Perforation in the duodenal bulb with a space of contrast pooling in the right upper abdomen.
92051729 Deformed duodenal bulb with a big ulcer.
92093868 Ulcer-case 2 A small ulcer at the lesser curvature of the mid gastric body.
