Kurzfassung:
The technique of laser en bloc resection of bladder tumor (ERBT) has been a valuable alternative technique to transurethral resection of bladder tumor (TURBT). However, the combination of laser ERBT and endoscopic submucosal dissection (ESD) technique has not been well studied. Here, a novel technique integrating a high-power green-light laser with ESD was presented. This study aimed to evaluate the safety and efficacy of high-power green-light laser endoscopic submucosal dissection (HPL-ESD) for the treatment of primary non-muscle-invasive bladder cancer (NMIBC). Materials and Methods: From January 2015 to December 2018, a total of 56 patients with NMIBC underwent HPL-ESD. All tumors were transurethral en bloc resected in the ESD technique. Perioperative clinical data were retrospectively collected and analyzed. Results: All operations were safely performed by the technique of HPL-ESD without blood transfusion. The mean tumor diameter was 2.04 ± 0.65 cm, ranging from 0.5 to 3.5 cm. The mean operative time was 28.39 ± 16.04 min. The average serum hemoglobin decrease was 0.88 ± 0.54 g/dL. The mean postoperative catheterization time was 2.88 ± 0.94 days. The pathologic stages included pTa (32 cases), and pT1 (24 cases). Double-J stent indwelling was not performed for four patients whose tumors were adjacent to the ureteral orifice and no postoperative hydronephrosis was observed. Only one case of ectopic bladder tumor recurred due to irregular bladder irrigation during the 36-month follow-up. Conclusion: HPL-ESD is a safe and effective alternative for the treatment of primary NMIBCs, especially for tumors adjacent to the ureteral orifice.
