The patient was referred to a surgical examination and a computed tomography (CT) im- aging with intravenous contrast was performed. CT scan has shown a dilated stomach, pyloric stenosis and intestinal malrotation (Fig. 1). The patient was admitted to the Military Medical Academy, Sofia, Bulgaria, for elective surgery one month later, in January 2020. Abdominal X-ray and gastroscopy were performed, in order to confirm the diagnosis. The X-ray has shown a left-sided large intestine (Fig. 2) and the gastroscopy has shown a dilated stomach due to pyloric stenosis, with inability to pass the gastroscope distally through the obstruc- tion (Fig. 3).

DISCUSSION Intestinal malrotation is a rare congenital dis- ease (0.2% of the new-born children) and it appears as a consequence of incomplete gut rotation and fixa- tion. It was first described in animals by Aristotle and in humans by Fabricii8. Intestinal rotation pri- marily involves the midgut. The rotation of intes- tinal development has been divided into 3 stages. Stage I occurs in week 5 to 10. It includes extrusion of the midgut into the extra-embryonic cavity, a 90° anti-clockwise rotation, and return of the midgut into the foetal abdomen. Stage II occurs in week 11 and involves further anti-clockwise rotation within the abdominal cavity, completing a 270° rotation. This rotation brings the duodenal „C“ loop behind the superior mesenteric artery with the ascending colon to the right, the transverse colon above, and descend- ing colon to the left. Stage III involves fusion and anchoring of the mesentery. The caecum descends, and the ascending and descending colon attach to the 9 Fig. 6.
