title: [Successful Resection of the Peritoneal Dissemination Recurrence of Colon Cancer, Including Metastasis to the Inguinal Hernia Sac--A Case Report].
abstract: We report a case of aggressive resection of synchronous and asynchronous peritoneal dissemination of colon cancer, including metastasis to the inguinal hernia sac. A 68-year-old man who was examined for anemia was diagnosed with ascending colon cancer. He underwent right hemicolectomy and resection of the disseminated tumors at the omentum and peritoneum near the Treitz ligament (moderately differentiated tubular adenocarcinoma, pT4a [SE] N0M1P2H0, stageⅣ). After 1 year 6 months, he was readmitted for intestinal obstruction due to the recurrence of peritoneal dissemination, and underwent partial resection of the ileum, liver, and right kidney. In the CT scan examination before surgery, right inguinal hernia and tumor were identified, and hernioplasty with resection of the inguinal tumor was subsequently performed after intestinal obstruction resolution. All tumors were identified as peritoneal dissemination of the colon cancer tumors by pathological examination. After surgery, he was treated with mFOLFOX6 for 6 months and survived without signs of recurrences despite the absence of treatment. Even in cases of peritoneal recurrence of colon cancer, aggressive resection may improve the prognosis in some cases.
