Intestinal malrotation complicated with gastric cancer: A case report

Figure 1 Imaging of the abdomen. A: 3D image acquired using RadiAnt DICOM VIEWER showing that the entire colon is on the right side of the abdomen; B: Digital radiography image showed the entire colon on the right side of the abdominal cavity; C: 3D image acquired using 3D Slicer image computing platform showing that the entire colon was on the right side of the abdomen; D: Coronal reconstruction of the computed tomography (CT) images showed the entire colon on the right side of the abdominal cavity; E: Transverse reconstruction of the CT images showed that the sigmoid colon was in the right iliac fossa.

Figure 2 Reconstruction images of the abdomen. A: Sagittal reconstruction of the computed tomography (CT) images showed the superior mesenteric artery (SMA) emanated from the abdominal aorta; B: Transverse reconstruction of the CT images showed the inferior mesenteric artery (IMA) originating from the abdominal aorta; C: Coronal reconstruction of the CT images showed the splenic vein joining the superior mesenteric vein (SMV), forming the portal vein; D: Coronal reconstruction of the CT images showed the inferior mesenteric vein (IMV) joining the SMV on the right side of the abdominal aorta; E: Coronal reconstruction of the CT images showed the IMV converging into the SMV as a result of mesentery malrotation; F: Transverse reconstruction of the CT images showed the SMA on the right to the SMV; G: Transverse reconstruction of the CT images showed the IMA and IMV running alongside the right side of the common iliac artery. SMA: Superior mesenteric artery; IMA: Inferior mesenteric artery; SV: Splenic vein; SMV: Superior mesenteric vein; IMV: Inferior mesenteric vein.

Figure 3 Laparoscopy findings during surgery. A: Laparoscopy revealed the absence of the gastrocolic ligament and transverse colon; B: Laparoscopy revealed that the left paracolic groove did not contain the colon; C: Laparoscopy revealed that the sigmoid colon was absent in the left iliac fossa; D: Laparoscopy revealed that the sigmoid colon was absent in the left iliac fossa; E: Laparoscopy revealed that both ascending and descending colon were on the right side of the abdomen; F: Laparoscopy revealed that the colon underwent a 180° rotation below the liver and descended behind the ascending colon; G: Laparoscopy revealed that the sigmoid colon was in the right iliac fossa.
