Abstract

Abstract:

Objective

To explore the safety and clinical efficacy of laparoscopic extended partial cystectomy in the treatment of adult urachal carcinoma.

Methods

The clinical data of 5 cases of urachal carcinoma treated by laparoscopic and Da Vinci robot-assisted laparoscopic extended partial cystectomy were analyzed retrospectively. The operation time, postoperative hospital stay, postoperative complications and tumor recurrence were analyzed to evaluate the effect of the operation. The resected regions included urachus, umbilical foramen, urachal mass, median umbilical ligament, part of peritoneum and the top of part of bladder connected with urachal mass. The relevant literature in Chinese or English were reviewed for the characteristics of urachal tumor imaging features and treatment.

Results

All the 5 cases were successfully operated without conversion to open surgery, little intraoperative blood loss, no serious postoperative complications. The mean operation time was 140 minutes and the average hospital stay was 7.4 days. No recurrence after follow-up for 1 to 4 years. Among those patients, one case was villous adenoma, three cases were mucinous adenocarcinoma of urachus and one case was invasive advanced urothelial carcinoma, all of them had no involvement of carcinoma in the margins and lymph nodes.

Conclusion

Laparoscopic extended partial cystectomy provides a relatively safe and effective method for the treatment of urachal carcinoma in adults.
