A 71 yo female patient from Tay ninh province, PARA =9007, 37kg in weight, suffered from an colicky abdominal pain for one month. Pain was getting worse and loss of bowel movement for 3 days. Ultrasound detected a dilatation from 3 to 4cm in diameter of small bowel and no air into the colon with a small amount of free fluid into her abdomen. CT disclosed a loop of small bowel which was between the right obturator and pectineus muscles and the small bowel obstruction.
In second look, ultrasound showed a loop of small bowel behind the muscle in the section of the right internal groin.
Surgery proved a loop of small bowel which entered the right obturator foramen that caused the bowel obstruction. The patient had got well post-op for one month but died as a recurrent pain later.
