膵体部非浸潤性膵管内乳頭腺癌に対し脾温存膵体尾部切除術を施行した1例

We report a case of non-invasive intraductal papillary-mucinous carcinoma that was performed spleen-preserving distal pancreatectomy. A 74-year-old man was admitted to our hospital because he was pointed out a cystic tumor of the pancreatic body by near doctor. Abdominal ultrasonography and endoscopic ultrasonography showed a cystic tumor with papillary elevated lesion. But there were no evidence of infiltration to another organs. Based on these various examinations a diagnosis non-invasive intraductal papillary-mucinous carcinoma was determined. Then we determined to perform a minimal invasive operation, and underwent spleen-preserving distal pancreatectomy. After the operation there were no major complications and he discharged on 45th post operative days. To determine the surgical procedure of non-invasive intraductal papillary-mucinous carcinoma, because of the high incidence of postoperative infections after splenectomy, we should try to preserve the organ function. It was considered that this procedure was a useful method for non-invasive intraductal papillary-mucinous carcinoma of the pancreas body.
