Blunt dissection method using HiQ+ soft coagulation system for laparoscopic cholecystectomy in acute cholecystitis

During laparoscopic cholecystectomy for acute cholecystitis, it is often difficult to keep the surgical view dry because of inflammation-related tissue fragility and susceptibility to bleeding. The resulting inadequate surgical view can lead to bile duct or vascular injury. Soft coagulation systems are used to achieve hemostasis during various surgeries; however, the usefulness of soft coagulation during laparoscopic cholecystectomy for acute cholecystitis is unclear. We here demonstrate the usefulness and feasibility of blunt dissection and soft coagulation during this procedure.

We used blunt dissection and soft coagulation when performing laparoscopic cholecystectomy on two patients with acute cholecystitis. As with conventional laparoscopic cholecystectomy, four ports were inserted. After cutting the serosa by electrocautery, blunt dissection using soft coagulation was performed, exposing the inner subserosa. Maintaining this layer using blunt dissection with soft coagulation achieved a sufficiently clear view for safety. After resecting the cystic artery and duct, the gallbladder bed was also dissected by blunt dissection with soft coagulation. Blood loss was <20 mL in both patients.

Blunt dissection with soft coagulation may be a useful and feasible means of keeping the surgical view dry and minimizing blood loss during laparoscopic cholecystectomy for acute cholecystitis.
