Midgut Malrotation with Chronic Abdominal Pain

Abnormalities in midgut rotation occur during the physiological herniation of midgut between the 5(th) and 10(th) week of gestation. The most significant abnormality is narrow small bowel mesentery which is prone to volvulus. This occurs most frequently in the neonatal period, less commonly midgut malrotation presents in adulthood with either acute volvulus or chronic abdominal symptoms. It is the latter group that represents a diagnostic challenge. We report a case of a 17-year-old male patient who presented with 10-year history of nonspecific gastro-intestinal symptoms. After extensive investigation the patient was diagnosed with midgut malrotation following computed tomography of abdomen. The patient was treated with a laparoscopic Ladd's procedure and at 3 months he was gaining weight and had stopped vomiting. A laparoscopic Ladd's procedure is an acceptable alternative to the open technique in treating symptomatic malrotation in adults. Midgut malrotation is a rare congenital anomaly which may present as chronic abdominal pain. Abdominal CT is helpful for diagnosis.
