AbstractWe recently performed a laparoscopic radical nephrectomy (LRN) on two patients with a renal cell carcinoma. Case 1, a 72-year-old man, was diagnosed as having a renal cell carcinoma 2.5 cm in diameter in the right kidney, and also a submucosal tumor of the cecum. LRN and laparoscopically assisted ileocecal resection were performed using a transperitoneal approach on September 28, 1999. Total operation time and blood loss during the operation were 308 minutes and 320 ml, respectively. The operation time needed for LRN, which was calculated as the total operation time minus the time spent on ileocecal resection, was 199 minutes. There were no complications after surgery, and the patient was recommended for discharge on the 7th postoperative day, but was actually discharged on the 10th postoperative day. Case 2, an 81-year-old man, was diagnosed as having a renal cell carcinoma 3.0 cm in diameter in the right kidney. He had been undergone a total gastrectomy for a gastric carcinoma at age 77, and a sigmoidectomy for a sigmoid colon carcinoma at age 79. A transperitoneal approach was applied for LRN to detect any recurrence of previous carcinomas on September 30, 1999. During adhesiolytic procedures, the colon was injured due to an inappropriate maneuver of the grasping forceps. A small laparotomy (5 cm) was required for repair of the colon. The total operation time and blood loss during surgery were 370 minutes and 850 ml. The operation time calculated from the video of LRN was 274 minutes. Two additional surgical procedures were required in this case. The first was for a postoperative intraperitoneal hemorrhage due to the hemoclip dropping out of the small vein. The second was for hemorrhage in the abdominal wall. Fortunately, the clinical course after surgery was good and the patient was discharged on the 8th postoperative day. There were no complications in case 1. Omitting ileocecal resection was considered to speed up oral intake, leading to earlier discharge. However, major complications occurred in case 2. It is important to clarify the cause of postoperative hemorrhage by careful observation of the video recording, in order to suggest safer procedures in laparoscopic surgery. Although these are only two LRN experiences, we are convinced that LRN can improve postoperative QOL (Quality of life) and is an acceptable alternative for the treatment of renal cell carcinomas.
