A 36-year-old man without previous medical history presented to the emergency department with abdominal pain and vomiting of acute onset. His vital signs were stable and he had no fever. Abdominal exploration revealed distention with pain at palpation. Laboratory tests were normal. Abdominal X-Ray showed gastric and small intestine distention. A nasogastric tube was placed and fluid therapy started. Computed tomography showed an intestinal malrotation, without the duodenum crossing the midline and with the colic frame arranged in the left hemiabdomen (Figure 1), complicated with a midgut volvulus as demonstrated by the whirlpool sign (Figure 2, arrow). Ladd’s procedure was performed using a midline open approach. Mesenteric lymphadenopathy and chylous ascites was found (Figure 3). The volvulus was reduced by counter-clockwise detorsion without need of intestinal resection and Ladd’s bands division along with an extended Kocher manoeuvre (Figure 4) allowed a good position of the mesentery. Appendectomy was also conducted. Postoperative course was uneventful with the patient being discharged the fifth day, after resumption of bowel function. No alterations were detected at follow up one month later.
Intestinal malrotation is a rare fetal developmental abnormality which may go unnoticed until adulthood. It can be an incidental finding or present with mild symptoms, but it can also lead to an intestinal obstruction or acute ischemia due to a midgut torsion requiring emergency surgery . Ladd’s procedure is the standard treatment. It was described in 1936 and consists in a repositioning of the intestine by lysing the abnormal fixations. Since it is an uncommon situation and due to challenging anatomy and possible difficulties in reducing the volvulus an open approach is usually preferred. Appendectomy is recommended in order to avoid failure or delay in diagnosis [2,3].
