Abstract

Highlights: Laparoscopic surgery may be safer and less invasive than laparotomy. Understanding anatomical abnormalities is useful to plan lymph node dissection. Extracorporeal lymph node dissection is useful in cases of intestinal malrotation. Abstract: Introduction: Intestinal malrotation is a congenital anatomical anomaly resulting from abnormal midgut rotation. Many cases occur during childhood and present with intestinal obstruction and midgut volvulus. Intestinal malrotation rarely occurs in adults and is found incidentally because it is asymptomatic. We herein report a case of intestinal malrotation, and colorectal cancer operated laparoscopically. Presentation of case: A 78-year-old man presented to our Department of Surgical Gastroenterology with fecal occult blood. There were no abnormal findings in the physical examination. Colonoscopy revealed a type 3 tumor in the cecum. Contrast-enhanced computed tomography revealed that the tumor was located in the appendix along the midline of the abdomen. The small intestine and colon occupied the right and left sides of the abdominal cavity, respectively. The diagnosis was appendiceal cancer with nonrotation-type intestinal malrotation. A laparoscopy-assisted ileocecal resection was performed. During surgery, the right-side colon was not fixed to the retroperitoneum, and the right-side colon could be extracted out of the abdominal cavity through the umbilical wound with only adhesive dissection, and mesenteric and lymph node dissection can be performed outside the body. The postoperative course was uneventful. Discussion: Appendiceal cancer with intestinal malrotation is managed with laparoscopic surgery because this method is safe and minimally invasive. Conclusion: The laparoscopic approach may be safer and less invasive than laparotomy, and extracorporeal lymph node dissection is safe and reliable for patients with intestinal malrotation.
