Abstract: Objective : To investigate the surgical technique and clinical effectiveness of Laparoscopic radical cystectomy. Methods : The method of tracheal-intubation anaesthesia was used. After general anaesthesia, prostrate position was posed and buttocks were raised in all the patients. The needles were inserted to create the pneumoperitoneum and the pressure at 12 to 15mmHg kept. The 10mm-Trocar-sheath units were punctured into the peritoneal cavity above the umbilicus. Results : The operating time was 256 to 476 minutes, (average 368 min), blood loss was 100 to 400m1 (average 248 m1). Oral intake started on hospital day 1 to 3 (average 1.5 days). Food-intake recovered at day 2 to 4 after operation and the patients were discharged from hospital about 8 to 13 days after operation. Histopathological examination of the specimens revealed transitional cell carcinoma gradeⅡ~Ⅲ, stage T2a 3 cases. No intraoperative or postoperative complications were observed. Follow-up 6 to 9 months after operation without the recurrence and metastasis. Conclusion : With more experiment and improvement of the surgical technique, the laparoscopic radical cystectomy boasts with minimum incision, limpid dissection, less intraoperative bleeding and rapid recovery, and is the safe and effective method for patients with localized muscle invasive bladder neoplasm.
