Synchronous laparoscopic resections of coexisting abdominal diseases are shown to be feasible without additional postoperative morbidity. We report our experience with synchronous laparoscopic resection of colorectal carcinoma and renal/adrenal neoplasms with an emphasis on surgical and oncologic outcomes. Five patients diagnosed to have synchronous colorectal carcinoma and renal/adrenal neoplasms (renal cell carcinoma in 2 patients, adrenal cortical adenoma in 2 patients, and adrenal metastasis in 1 patient) underwent synchronous laparoscopic resection. The median operative time was 420 minutes and the median operative blood loss was 1000 mL. Three patients developed minor complications, including wound infection in 2 patients and retention of urine in 1 patient. There was no operative mortality. The median duration of hospital stay was 11 days. At a median follow-up of 17.6 months, no patient developed recurrence of disease. Synchronous laparoscopic resection of colorectal and renal/adrenal neoplasms is technically feasible and safe.
