[A Case of Laparoscopic Ileus Release for Intestinal Obstruction Due to Small Intestinal Metastasis Four Years after Penile Cancer Surgery].

We report a rare case of metastatic small intestine cancer originating from penile cancer triggered by intestinal obstruction, with some review of the literature. The case was a 78-year-old man at the first visit. Partial penile resection was performed for penile cancer. Histopathological findings were squamous cell carcinoma, and the surgical margin was negative. The stage at the time of the first surgery was T2N0M0, Stage Ⅱ. He came to the hospital with a complaint of abdominal pain 4 years after the operation. He was diagnosed with intestinal obstruction and was treated medically. He underwent medical treatment for 12 days, but did not improve, so he underwent laparoscopic ileus release. Surgical findings showed a neoplastic lesion in the abdominal cavity, and the site was obstructed, and partial resection of the small intestine including the neoplastic lesion was performed. Pathological examination revealed small intestinal metastasis of penile cancer. Postoperative intestinal obstruction improved and he was discharged without complications. After discharge, he underwent systemic chemotherapy at an outpatient clinic, but died of the primary disease 181 days after intestinal obstruction.
