Abstract
Background and Purpose: The incidence of bladder diverticular carcinoma is low, ranging from 0.8% to 10%. Traditionally, treatment consisted of open surgical excision or transurethral resection. More recently, laparoscopic surgery has become widely accepted. We report here a case of bladder diverticular carcinoma treated with laparoscopic partial cystectomy. Case Report: A 56-year-old man presented with gross hematuria and was found to have transitional-cell carcinoma in a bladder diverticulum. We performed transurethral resection of the tumors and laparoscopic partial cystectomy. A 45-mm Endo-GIA stapler (U.S. Surgical Corp., Norwalk, CT) was used for direct resection of the diverticular tissue, and the specimen was removed en bloc. Suture of the seromuscular layer was performed with the intracorporeal knotting technique. Lymph-node dissection also was performed. At 3-month follow-up, it was noted that there was tumor recurrence that was not at the original diverticular site, and transurethral resection was carried out. After 1 year, cystoscopy and CT scans showed neither recurrence nor metastasis. No encrustation or erosion was induced by the staples. Conclusion: Laparoscopic partial cystectomy can be an alternative treatment for bladder diverticular carcinoma.
