Technology assessment of endoscopic surgery

Area of Science:

• Surgical Technology Assessment
• Minimally Invasive Surgery
• Health Technology Evaluation

Background:

• Endoscopic surgery represents a significant advancement in surgical techniques across various specialties.
• The widespread adoption of new endoscopic technologies necessitates critical evaluation to ensure patient safety and efficacy.
• Concerns exist regarding the inappropriate application of endoscopic surgical techniques, demanding systematic assessment.

Purpose of the Study:

• To outline methods for technology assessment specifically tailored for endoscopic surgical techniques.
• To emphasize key endpoints relevant to both surgeons and patients in evaluating endoscopic procedures.
• To demonstrate the application of technology assessment principles using laparoscopic cholecystectomy as a case study.

Main Methods:

• Described a four-stage technology assessment framework: feasibility, efficacy, effectiveness, and economic evaluation.
• Utilized a cohort study of 500 patients undergoing laparoscopic cholecystectomy.
• Evaluated endpoints including postoperative pain, convalescence, fatigue, and quality of life.

Main Results:

• Laparoscopic cholecystectomy demonstrated safety equivalent to the conventional open surgical approach.
• Efficacy results indicated enhanced patient comfort and reduced trauma associated with the endoscopic technique.
• Data regarding effectiveness and economic impact were preliminary and require further investigation.

Conclusions:

• Technology assessment is essential for validating the benefits and risks of endoscopic surgical techniques.
• Laparoscopic cholecystectomy is a safe and patient-preferred alternative to open surgery based on initial efficacy data.
• Other surgical disciplines, including neurosurgery, should adopt structured technology assessment frameworks for their endoscopic procedures.
