Novel approach of laparoscopic transperitoneal en bloc resection of urachal tumor and umbilectomy with a comparison of various techniques.

Urachal carcinoma is a rare cancer that accounts for less than 1% of all bladder cancers. Surgical resection remains the mainstay of treatment. With partial cystectomy, long-term survival is possible following complete resection of the tumor. In this paper, we describe a novel approach of laparoscopic en bloc partial cystectomy and umbilectomy. We emphasize the importance of complete resection of the tumor and umbilicus and prevention of tumor spillage during the procedure. The literature is also reviewed for the comparison of various laparoscopic techniques.
