インドシアニングリーン蛍光を用いた腹腔鏡下胆嚢摘出術:胆管鏡下結石摘出および一次管縫合

Overview

This protocol presents an integrated technique for real-time biliary mapping using indocyanine green (ICG) fluorescence, facilitating minimally invasive stone clearance and secure primary duct repair.

Key Study Components

Area of Science

• Minimally invasive surgery
• Fluorescence imaging
• Biliary tract procedures

Background

• Common bile duct stones pose significant surgical challenges.
• Traditional methods often require T-tube drainage.
• Fluorescence cholangiography enhances visualization during surgery.
• Direct visualization techniques improve outcomes in biliary surgery.

Purpose of Study

• To optimize a minimally invasive protocol for stone removal.
• To achieve primary duct closure without the need for T-tube drainage.
• To utilize fluorescence imaging for precise surgical navigation.

Methods Used

• Infraumbilical incision for trocar placement.
• Use of multiple trocars for laparoscopic access.
• Color fluorescence mode for imaging biliary structures.
• Adjusting imaging gain for optimal visualization.

Main Results

• Successful real-time biliary mapping achieved.
• Minimally invasive stone clearance demonstrated.
• Primary duct repair completed without T-tube drainage.
• Enhanced visualization of biliary anatomy confirmed.

Conclusions

• The integrated technique improves surgical outcomes.
• Fluorescence imaging is effective for biliary procedures.
• This protocol may reduce complications associated with traditional methods.
