Abstract:

Objective To investigate the safety and efficacy of open gasless minimum incision endoscopic radical cystectomy （MIE-RC） to treat patients with muscle-invasive bladder cancer. Methods Clinical data， operative parameters and outcomes were analyzed in 14 patients undergoing MIE-RC. Results All operations were successful. Median operating time was 363 min（270-518 min） for all procedures，including MIE-RC，bilateral pelvic lymphadenectomy and urinary diversion. Median estimated blood loss was 540 ml（260-1 400min）. Restoration of bowel function， defined by the time until flatus and bowel movement，took an average of 4.3 days. Mean time until drainage tube removal was 10.2 days，and mean length of postoperative hospitalization was 33 days. No instances of major vascular injury，rectal injury，urinary incontinence， urinary leakage or intestinal leakage were observed. No cases of tumor recur-rence or disease-specific death were observed during follow-up lasting 6-28 months. Conclusions Open gasless MIE-RC appears to be safe and reliable and should be promoted.
