A Study Of Reducing Emissions Of Robotic Surgical Approaches Through Transdisciplinary Studies

Overview

About this study

The purpose of this study is to compare the environmental and clinical impacts of elective robotic cholecystectomy (RC) and laparoscopic cholecystectomy (LC) for benign disease.

Participation eligibility

Participant eligibility includes age, gender, type and stage of disease, and previous treatments or health concerns. Guidelines differ from study to study, and identify who can or cannot participate. There is no guarantee that every individual who qualifies and wants to participate in a trial will be enrolled. Contact the study team to discuss study eligibility and potential participation.

Inclusion Criteria:

  • Adults aged ≥18 years.

  • Body mass index (BMI) < 40 kg/m².

  • Diagnosed with a benign condition (cholelithiasis, biliary dyskinesia, …) and scheduled for elective RC or LC.

  • ASA classification I–III.

  • Ability to provide informed consent.

Exclusion Criteria:

  • Patient-related factors:

    • Pregnancy.

    • Inability to provide informed consent

    • Body mass index (BMI) > 40 kg/m².

  • Surgical indications:

    • Acute or complicated procedures (e.g., cholecystitis with hydrops, empyema, abscess, gangrene, or sepsis).

    • Malignancy.

  • Additional procedures:

    • Patients scheduled for additional simultaneous surgical procedures (e.g., hernia repair, hepatopancreatobiliary procedures, bariatric surgery, oncologic surgery).

    • Reoperations related to prior cholecystectomy or biliary interventions.

    • Cases requiring intraoperative cholangiography.

  • Intraoperative complications:

    • Conversion to open surgery.

    • Severe intraoperative bleeding requiring blood transfusion.

    • Major bile duct injury.

    • Visceral injury requiring surgical repair (e.g., bowel, liver, or diaphragm perforation).

    • Hemodynamic instability during the procedure.

Note: Postoperative complications will not lead to exclusion from the study.

Note: Other protocol defined Inclusion/Exclusion Criteria may apply.
