Abstract
(BACKGROUND). The clinical outcome of laparoscopic surgery performed in 143 patients, including laparoscopic adrenalecotmy, nephrectomy, pelvic lymph node dissection (PLND) and varicocele ligation is reported. (METHODS). In patients who underwent laparoscopic adrenalectomy (32 cases), laparoscopic nephrectomy (7) or PLND (44), the following parameters were evaluated and compared to those obtained in patients undergoing the same surgeries but by conventional open procedure; operation time, hospital stay, pain killer doses and the time necessitated for ambulation. (RESULTS). The operation was successful in 95.8% (137/143). Open laparotomy was necessitated in 4 patients to control bleeding (two in adrenalectomy and two for PLND) and in one nephrectomy case due to massive adhesion with the descending colon. The major complication occurred in 4.2% of the cases, but without mortality. The laparoscopic adrenalectomy, nephrectomy and PLND had an average operating time of 260, 304 and 139 minutes, respectively, while the open surgery for each procedure required 251, 212 and 128 minutes, respectively (p = 0. 24 approximately 0.82). Likewise, the total dose of pain killer was 0.8, 1.8 and 0.9 for the former, whereas it was 3.2, 6.0 and 3.9 for the latter, respectively (p < 0.01). The average hospital stay for laparoscopic surgery was 4.9, 6.4 and 4.7 days in the same order, whereas open adrenalectomy or nephrectomy required about 14 days (p < 0.001). Convalescence was completed within significantly shorter term in patients with laparoscopic surgery. Potential complications of laparoscopic surgery included not only those unique to pneumoperitoneum (8.1%), but also those which may be encountered during any endoscopic operation such as compartment syndrome in the lower extremities. The physiologic changes accompanying increased intra-abdominal pressure affected renal function, characterized by a significant decrease in urinary output (p < 0.02), which, however, resumed to normal range within several hours after the operation without causing permanent renal dysfunction. (CONCLUSION). These results suggest that the laparoscopic surgery in certain area in urology has less morbidity and equal accuracy compared with conventional open surgery.
