title: [A patient treated with partial duodenectomy for invasive transverse colon cancer].
abstract: The patient was an 83-year-old woman who visited our hospital with a chief complaint of weight loss. Duodenal invasion by transverse colon cancer was suspected on abdominal computed tomography( CT). An extramural tumor invading the second portion of the duodenum was noted on upper gastrointestinal endoscopy, and a circumferential type 2 lesion was observed in the transverse colon on lower intestinal endoscopy. The pathological diagnosis of both lesions was well-differentiated adenocarcinoma, and right hemicolectomy and partial duodenectomy were performed. The invaded duodenal region was located on the oral side of the papilla of Vater, and the resection involved approximately one-third of the circumference of the second portion of the duodenum and was approximately 5 cm in length. The jejunum was elevated using the Roux- en-Y method, and side-to-side duodenojejunostomy was performed for reconstruction. On histopathological examination, the lesion was diagnosed as SI, N0, Stage II. Tumor markers with elevated levels before surgery showed a rapid decrease to within normal ranges. No evidence of recurrence or metastasis has been observed for 3 years after surgery. Although pancreatoduodenectomy is the standard surgical procedure for duodenal tumorous lesions, this approach is very invasive for elderly patients. Partial duodenectomy may be a favorable treatment option for cancers invading other organs, as was the case for this patient.
