Small bowel series
Small Bowel Duodenum Jejunum Ileum Large Intestine cecum
Small bowel series 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. Small intestine
Small bowel series Ascending (4th) part of duodenum SMA Superior (1st) part of duodenum Descending (2nd) part of duodenum Horizontal (3rd) part of duodenum Duodenojejunal flexure
Small bowel series Diverticulum at the 2nd portions of the duodenum.
Small bowel series Duodenal diverticulum, second portion
Small bowel series Edematous change of mucosal fold & wall thickness; Partial obstruction over ileum Poor peristasis of small bowel, consistent with adhesion.
Small bowel series Obstruction-case 1
Small bowel series Obstruction-case 2 Disproportional dilatation of jejunum ， suggest obstruction
Small bowel series The obstruction level should be around distal jejunum
Small bowel series
Small bowel series Obstruction-case NG placed in duodenum
Small bowel series There is extrinsic compression at distal third portion of duodenum ， probable due to vascular indentation
Small bowel series 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.
Small bowel series 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
Small bowel series Obstruction-case 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
Small bowel series
Smooth margin filling defect in the cecum. D/D cecal tumor or postappendectomy change
Small bowel series Soft tissue mass over LUQ area with mass effect to stomach and bowel loops noted Mass effect-case 2
Small bowel series An ovoid filling defect within the lumen of the 2nd portion of the duodenum; c/w duodenal tumor. Mass effect-case 3
Small bowel series Mass effect-case 4. Diffuse dilated duodenum and proximal jejunum
Small bowel series Persistent, long segmental luminal narrowing at the proximal jejunum with "beak" appearance of the proximal small bowel, malignancy like jejunal Ca. is considered
Small bowel series Marked dilatation of small bowel loops (mainly are jejunum) with contrast medium stasis during the procedure. Intestinal partial obstruction at jejunum, r/o adhesion.
Small bowel series Fistula formation (vagina and ileum) at RLQ
Small bowel series 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.
Small bowel series 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
Small bowel series 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.
Small bowel series Deformed duodenal bulb with a big ulcer.
Small bowel series Ulcer-case A small ulcer at the lesser curvature of the mid gastric body.
