An 18-year-old male patient with cerebral palsy and scoliokyphosis came to the emergency department with abdominal distension and vomiting. He was a situs inversus patient with a feeding gastrostomy tube. Sigmoid volvulus was initially suspected, so rectal tube insertion and endoscopic decompression were attempted, but failed. So he went through explorative laparotomy, and transverse colonic adhesion and twisting around the gastrostomy tube and gastric wall was identified. Adhesiolysis and resection with redundant transverse colon and end-to-end colocolic anastomosis was performed. He discharged with symptom free. Suspecting transverse colonic volvulus is important when the patient has anatomical anomalies and feeding gastrostomy tube. Timely diagnosis with proper radiologic imaging should be made. Surgical resection of the redundant colon is needed for successful management of transverse colonic volvulus.

Situs inversus abdominis is a rare congenital condition commonly associated with serious cardiac and splenic malformations. The importance of recognizing the presence of situs inversus abdominis preoperatively is emphasized by the fact that the surgical incision is placed on the incorrect side of the abdomen. A 6 day-old girl was referred to our hospital because of bile stained vomiting. A plain radiography of abdomen and chest showed the heart to be normal position and a reversed "double-bubble" picture with no other gas shadow in the rest of the abdomen. Abdominal computed tomography scan revealed situs inversus with the stomach and polysplenia on the right side and the liver on the left side. A laparotomy confirmed the diagnosis of situs inversus with duodenal atresia. The obstruction was bypassed by constructing a side-to-side duodenoduodenostomy. The postoperative course was uneventful.
