What condition does this patient have and how is it treated? (Fig. 1)

- Gallstone ileus and enterolithotomy.
- Malrotation and detorsion of small bowel.
- Meckel's diverticulum and diverticulectomy.
Answer – 3 Gallstone ileus and enterolithotomy
Gallstone ileus is a rare complication of cholelithiasis, but an established cause of mechanical small bowel obstruction in elderly patients. It is associated with high morbidity and mortality as most patients are elderly with multiple comorbidities. Surgery of choice is enterolithotomy alone in unstable patients and it is associated with lower morbidity and mortality, lower operative time, and shorter hospital stay. Interval cholecystectomy with fistula repair can be performed in these patients once they have recovered from the acute episode. The other surgical option in young and stable patient is to perform enterolithotomy, cholecystectomy, and fistula repair in one stage [1, 2].
