“…En bloc resection was achieved in all eight gastric ESD (five ex vivo and three in vivo) cases, and there was no perforation, MP layer injury, or uncontrollable hemorrhage observed during the procedures. 11 The diode laser system has been used for a variety of surgeries, such as prostate disease surgery, 21 endovenous ablation treatment, 22 tonsillectomy, 23 and laser-assisted laparoscopic partial nephrectomy, 24 and has proven to be effective for tissue excision and hemostasis. Tang et al 14 demonstrated the feasibility of ESD using diode laser in an animal model.…”

Background/Aims: A new medical fiber-guided diode laser system (FDLS) is expected to offer high-precision cutting with simultaneous hemostasis. Thus, this study aimed to evaluate the feasibility of using the 1,940-nm FDLS to perform endoscopic submucosal dissection (ESD) in the gastrointestinal tract of an animal model. Methods: In this prospective animal pilot study, gastric and colorectal ESD using the FDLS was performed in ex vivo and in vivo porcine models. The completeness of en bloc resection, the procedure time, intraprocedural bleeding, histological injuries to the muscularis propria (MP) layer, and perforation were assessed. Results: The en bloc resection and perforation rates in the ex vivo study were 100% (10/10) and 10% (1/10), respectively; those in the in vivo study were 100% (4/4) and 0% for gastric ESD and 100% (4/4) and 25% (1/4) for rectal ESD, respectively. Deep MP layer injuries tended to occur more frequently in the rectal than in the gastric ESD cases, and no intraprocedural bleeding occurred in either group. Conclusions: The 1,940-nm FDLS was capable of yielding high en bloc resection rates without intraprocedural bleeding during gastric and colorectal ESD in animal models. Clin Endosc 2021 Jan 13.

“…In a study by He et al comparing HoLEP and diode laser enucleation, a Hawk morcellator was used in all patient groups, and no bladder injury, perforation, or injury in the urethral orifices were observed in any groups (23). In a more recent study in which Hawk morcellator was used after prostatic enucleation, no bladder injury occurred in any patient (27). In a study in which Thulium laser enucleation of the prostate and resection were compared, and Hawk morcellator was used, mucosal bladder injury was observed in 3 patients (1.6%) in the enucleation group in which a morcellator was used; however, no statistically significant difference was found between groups (p= 0.065).…”

Objective: Although morcellation is a standard procedure of Holmium Laser Enucleation of the Prostate (HoLEP), studies on the morcellators used are limited in number. We aimed to compare two different tissue morcellators used in HoLEP, which have similar objectives but differences in efficiency and safety in working principles. Material and Methods: The data of 130 patients who underwent HoLEP between December 2018 and December 2019 were retrospectively reviewed. Sixty-five patients received Lumenis® Versacut (Lumenis Inc., Santa Clara, CA, USA) morcellator and 65 patients received Hawk® JAWS (Hawk, Minitech Co., China) morcellator after enucleation were included in the study. The efficiency of morcellation (g/min), morcellation time (min), total operation time (min), enucleation time (min), enucleated tissue weight (g), the efficiency of enucleation, densities of the removed prostate tissues, perioperative complications associated with the use of a morcellator were recorded perioperatively. Results: There was no significant difference in total operation time (min), enucleation time (min), enucleated tissue weight (g), and efficiency of enucleation (g/min) efficiency of morcellation, morcellation time (min) between the two groups. Bladder mucosal damage occurred in 3 patients (4%) in the Versacut group, while mucosal bladder damage was not observed in any patient in the Hawk® JAWS group (p = 0.08). Conclusion: Hawk® JAWS and Lumenis® VersaCut morcellators were comparable in their efficiency and safety. Keywords: Hawk, HoLEP, morcellation, morcellator, Versacut.

“…It works at a wavelength of 1470 nm which is absorbed by both water and hemoglobin. Due to its excellent tissue vaporization capacity and great coagulation properties, the 1470 nm laser has been widely used in the operative management of benign prostatic hyperplasia, with demonstrated safety and efficacy [ 5 ]. Similarly,our results showed that the patients treated with the 1470 nm laser for hemostasis had a smaller decrease in hemoglobin and shorter hospital stay than patients undergoing routine tubeless PNL.…”

“…The 1470 nm diode laser has the superiority of highly efficient tissue vaporization and the creation of a stable coagulation layer [ 4 ]. Therefore, the 1470 nm laser vaporization treatment has become an important surgical method to protect patients against BPH [ 5 ]. Moreover, the 1470 nm laser appears to be a safe and effective treatment to treat parapelvic renal cysts, due to its excellent hemostatic effects and incision power [ 6 ].…”

Objective It is challenging to perform a tubeless percutaneous nephrolithotomy (PNL) in patients with tract bleeding. The present study was designed to study the safety and efficacy of the 1470 nm laser for hemostatic completion in tubeless PNL patients with tract bleeding. Patients and Methods Between January 2020 and October 2021, 120 patients were retrospectively included and divided into two groups. The hemostasis group included 60 patients receiving tubeless PNL, in which a 1470 nm laser was used to manage tract bleeding. The other group included 60 patients receiving tubeless PNL in which the hemostasis procedure was not performed, serving as the control group. The differences in the patients’ demographic characteristics, procedural information, and posttreatment outcomes between the two groups were statistically compared. Results The differences associated with sex, age, weight, body mass index, urine culture, stone burden, calyx of puncture, degree of hydronephrosis and comorbidities between the two groups were not statistically significant. Compared with the control group, the hemostasis group showed greatly reduced blood loss (0.61 ± 0.31 vs. 0.85 ± 0.46 g/dL) and decreased postoperative hospitalization duration (2.83 ± 0.81 vs. 4.45 ± 0.91 days). The differences in operative time, stone-free rate, Visual Analogue Score and postoperative complications between the two groups were not statistically significant. In the subgroup analysis, the obese patients and patients with moderate to severe hydronephrosis in the hemostasis group also showed a significantly less blood loss (0.51 ± 0.22 vs. 0.83 ± 0.48 g/dL; 0.54 ± 0.27 vs. 0.85 ± 0.47 g/dL, respectively) and shorter length of postoperative hospitalization (2.62 ± 0.51 vs. 4.47 ± 1.19 days; 2.97 ± 0.63 vs. 4.41 ± 0.91 days, respectively) than those in the control group. Conclusions Our results demonstrated that 1470 nm laser is a safe, feasible and effective method to obtain tract hemostasis in tubeless PNL.
