Several studies suggest that water-soluble contrast agents may be used for the diagnosis of resolution of obstruction, predicting the need for surgical intervention and simultaneously, can be used for conservative treatment of ASBO by stimulating the bowel movement due to their hyperosmolar effect and water movement into the small bowel lumen
(2) We recommend segmental resection for multifocal lesions, lesions larger than 3 cm, or for lesions involving more than one-third of the bowel lumen
. (37,44,45,47) Disc resection is appropriate for lesions smaller than 3 cm even if the bowel lumen
Most often an abdominal computed tomography helps to delineate the extent of disease, bowel lumen
dimensions, adhesions, congenital anomalies, etc.
If the process continues for a few hours, the secondary pathology, bowel ischaemia and gangrene, and related clinical features are supervened.4,13 In addition to the initial hypovolemia, due to volume loss into the obstructive bowel lumen
, necrosis facilitates bacterial translocation and the absorption of toxic products, resulting in toxaemia.2
Colonoscopy revealed a polypoidal mass obstructing the whole bowel lumen
with features of intussusception 120 cm from the anal verge.
Depending on the area of tumor invasion, the bowel lumen
may be narrowed or have aneurysmal dilation.
In summary, this new protocol for MR rectography, which using isosmotic mannitol instead of US gel to distend bowel lumen
after bowel cleansing, has shown to be a feasible method to improve image quality and lesion depictures of RC through eliminating an effect of gas and feces.
The treatment options for bowel endometriosis depend on size and location of the lesion, stenosis of bowel lumen
, severity of the symptoms, desire of patient to conceive and tolerability of hormonal therapies (4, 7).
Mesenteric vessels located in the bowel lumen
may also help to establish a final diagnosis (4).
(2) In the present case, ileostomy was done considering the poor general condition of the child and the disparity in size of the bowel lumen
[K.sup.+] is also lost to the bowel lumen
. Later on, serum [H.sup.+] is increased due to anaerobic metabolism and lactic acid production.
This afforded significant mobility as the plastic sheath could be rotated and torqued within the bowel lumen
, allowing for optimal positioning of the endoscope and forceps to retrieve foreign bodies.
