Background: We aimed to determine the optimal bipolar electrocoagulation power for laparoscopic surgery and to investigate which method, bipolar electrocoagulation, advanced bipolar, or ultrasonic technique was more reliable.
Methods: Goat mesenteric vessels (210 in vivo samples) with diameters of 3.03-5.44 mm were selected. Bipolar electrocoagulation with 80 W, 75 W, 70 W, 65 W, 60 W, 55 W, and 50 W, and advanced bipolar and ultrasonic techniques were performed on mesenteric vessels. The thermal damage width, hemostatic effect, and burst pressure of these tissues were recorded. SPSS version 13.0 was used for all data analysis.
Results: The results showed that 60 W was the optimal for bipolar electrocoagulation based on the thermal damage width, hemostatic effect, and burst pressure. In contrast, the thermal damage width of advanced bipolar and ultrasonic techniques was smaller than that of bipolar electrocoagulation, and advanced bipolartechnique had the highest successful rate for hemostasis and highest burst pressure.
Conclusions: Bipolar electrocoagulation was optimally performed with 60 W of power. Compared with ultrasonic and bipolar electrocoagulation techniques, advanced bipolar use was more reliable for mesenteric vessels in laparoscopic surgery; however, bipolar electrocoagulation with optimal power can be used for its simplicity of operation and low cost.

Introduction: Acquired bladder diverticulum (BD) is typically managed using open, laparoscopic, or robotic approaches. Although transurethral techniques demonstrated favorable outcomes in the 1970s and 1980s, they have largely fallen out of favor. This study revisits transurethral endoscopic management of large, symptomatic BD, combined with Holmium laser enucleation of the prostate (HoLEP) for patients with benign prostatic obstruction (BPO) and coexisting BD.

With the development of endoscopic technology, neuroendoscopy utilizes its advantages such as good illumination, close range observation, and flexible degrees of freedom. Neuroendoscopic surgery can achieve advantages such as minimally invasive, high clearance rate, low incidence of complications, good brain tissue protection, and fewer surgery-related injuries. However, minimally invasive endoscopic surgery also has inherent limitations, since its narrow surgical channels are prone to collapse and require special instrument support.

This study aimed to evaluate the electrical characteristics of the da Vinci system's bipolar soft coagulation mode and to assess its feasibility for dividing incomplete pulmonary interlobar fissures during robot-assisted thoracoscopic surgery. The electrical properties of the bipolar soft coagulation mode were analyzed using an electrocautery analyzer. Additionally, safety was assessed through experiments on animal tissue with an infrared thermographic camera.

Objective: To compare the long-term outcomes, postoperative pain, and complications of bipolar electrocautery (BEC) and radiofrequency coagulation (RFC) in the treatment of pediatric patients with recurrent anterior epistaxis (RAE) and allergic rhinitis (AR).
Materials And Methods: Children presenting with RAE and AR were prospectively semi-randomized to receive BEC or RFC during the 2-year period. We recorded the occurrence of recurrent epistaxis as well as epistaxis severity scores (ESSs) and visual analogue scale (VAS) scores for AR-related symptoms.
