[A Case of a Patient with Type Ⅳ Adachi Classification Treated with Laparoscopic Ileocecal Resection].

A 72-year-old woman was diagnosed with cecal cancer. Preoperative enhanced abdominal computed tomography(CT) and three-dimensional(3D)-CT angiographyrevealed a celiacomesenteric trunk(CMT). We performed a laparoscopic ileocecal resection without anyproblems owing to the obtained preoperative 3D-CT images. The postoperative course was uneventful. The celiac arteryhas manyanomalies, and 6 categories have been defined. Patients can be divided into 28 groups bycombining these anomalies with mutations in the hepatic artery, as explained byAdachi. Our case was a Type Ⅳ anomaly according to the Adachi classification, which accounts for 2.4% of all cases. We herein report this extremelyrare case.
