What is the purpose of traction sutures during common duct explorations?

The purpose of traction sutures during common duct explorations is to hold the duct open. This technique is crucial during surgical procedures as it provides better visibility and access to the ductal structure, allowing the surgeon to perform necessary interventions. By keeping the duct open, the traction sutures facilitate the removal of stones or other obstructions and allow for an unimpeded view of the surgical field.

In contrast, options like ligating the duct or closing it permanently would not only defeat the purpose of the exploration and intervention but could also lead to serious complications. Additionally, sealing stones inside would prevent their removal and could exacerbate issues related to obstruction or infection. Therefore, the use of traction sutures is specifically tailored to enhance the surgical approach during common duct procedures.
