Summary
This study reports a rare case of a 69-year-old male with rectal cancer and crossed renal ectopia (CRE). The patient successfully underwent laparoscopic surgery for rectal cancer with no complications.
Area of Science:
- Urology
- Surgical Oncology
- Radiology
Background:
- Crossed renal ectopia (CRE) is a congenital anomaly where a kidney is located on the contralateral side of the abdomen.
- Rectal cancer is a common gastrointestinal malignancy.
- The co-occurrence of CRE and rectal cancer is infrequently observed.
Observation:
- A 69-year-old male presented with rectal cancer.
- Computed tomography revealed concurrent crossed renal ectopia (CRE).
Findings:
- The patient underwent successful laparoscopic radical resection for rectal cancer.
- Adequate lymph node removal was achieved.
- No postoperative complications were noted.
Implications:
- This case demonstrates the feasibility of surgical management for rectal cancer in patients with CRE.
- Multidisciplinary collaboration is crucial for managing complex anatomical variations during oncological surgery.
- Further research may explore optimal surgical strategies for patients with coexisting CRE and rectal cancer.
