Complications of staging laparoscopic pelvic lymphadenectomy

Fifty-four patients underwent staging laparoscopic pelvic lymphadenectomy under general anesthesia for prostatic carcinoma (49), bladder carcinoma (3), penile carcinoma (1), and lymphoma (1). Conversion to an open procedure occurred only once in the series, but three patients received secondary open operations (5.5%). Complications recognized intraoperatively included bladder perforation (2) and mesenteric hematoma (1). One bladder perforation was repaired laparoscopically. The other was treated with catheter drainage. The mesenteric hematoma was explored surgically and found to be minor. Major postoperative complications included bleeding (4) requiring transfusion in two patients. One hematoma became infected requiring percutaneous drainage. One patient required intubation due to chronic obstructive pulmonary disease (COPD). Ureteral injury (1) was recognized late and required a psoas hitch and ureteroneocystostomy. Two patients developed small bowel obstructions due to herniation through a trocar site, requiring operative correction. Minor postoperative complications included ileus (4), diarrhea (2), bronchospasm (1), transient obturator nerve palsy (1), electrocardiogram changes (1), and fever (1). The overall major complication rate was 16.7%, and the overall minor complication rate was 18.4%. In this series, a substantial learning curve was seen with regard to complications, but the series compared favorably with open lymphadenectomy.
