There is an abnormal position of the caecum which passes through the foramen of Winslow to lie within the lesser sac. The foramen of Winslow is widened with the main portal vein partially effaced by the adjacent large bowel.

There is a small volume of free intra-vesical gas, with no IDC and preservation of the fat plane around the bladder. 3.4 cm ovoid hypodense right adnexal lesion.
Conclusion:
Internal herniation of the caecum into the lesser sac. No small bowel obstruction.
