Laparoscopic right hemicolectomy for a patient with idiopathic retroperitoneal fibrosis: A case report.

A 62-year-old man with abdominal pain and lumbago was admitted to our hospital. Blood examination revealed renal insufficiency, and CT revealed retroperitoneal fibrosis causing bilateral hydrocele and ureteral compression. A colonoscopy was performed to rule out secondary retroperitoneal fibrosis due to malignancies, and this imaging revealed an ascending colon cancer. Laparoscopic right hemicolectomy with lymphadenectomy and retroperitoneal biopsy were performed. The retroperitoneum was filled with hard, white fibrous tissue, which made it difficult to mobilize the right mesocolon from the retroperitoneum. Devascularization performed before mobilization allowed for a safe and oncologically feasible procedure. Histologically, there were no malignant cells in the retroperitoneal tissue. The patient has been without colon cancer reoccurrence for 4 years. When the surgical challenges that distinguish these patients from ordinary cases are recognized preoperatively, laparoscopic colectomy may be a feasible option for patients with colorectal cancer with idiopathic retroperitoneal fibrosis.
