Definition

Minimally Invasive Surgery (MIS) refers to surgical techniques performed through small incisions using specialized instruments and visualization tools, aiming to reduce tissue damage, pain, and recovery time compared to traditional open surgery.

History

Early Foundations

  • Endoscopy Origins (1806): Philipp Bozzini developed the “Lichtleiter” to inspect internal organs using candlelight.
  • Laparoscopy Introduction (1910): Hans Christian Jacobaeus performed the first laparoscopic surgery on humans, initially for diagnostic purposes.

Technological Milestones

  • Fiber Optics (1950s): Harold Hopkins’ advancements enabled flexible endoscopes, improving visualization.
  • First Laparoscopic Cholecystectomy (1985): Erich Mühe performed the first gallbladder removal using laparoscopy, marking a pivotal shift to MIS.

Key Experiments and Discoveries

Animal Trials

  • Pioneering Procedures: Early MIS techniques were tested on animals to assess safety and feasibility, leading to rapid adoption in human surgery.

Human Trials

  • Randomized Controlled Trials (RCTs): Studies compared outcomes of MIS vs. open surgery, demonstrating reduced postoperative pain, faster recovery, and lower infection rates.

Instrumentation Advances

  • Development of Trocar and Cannula: Enabled safe access to body cavities.
  • Camera Miniaturization: Allowed high-definition visualization with minimal invasiveness.

Modern Applications

General Surgery

  • Laparoscopic Appendectomy: Standard for appendicitis treatment.
  • Laparoscopic Cholecystectomy: Preferred method for gallbladder removal.

Orthopedics

  • Arthroscopy: Used for joint repair, especially knee and shoulder.

Cardiothoracic Surgery

  • Video-Assisted Thoracoscopic Surgery (VATS): Minimizes trauma in lung and heart procedures.

Neurosurgery

  • Endoscopic Brain Surgery: Accesses deep brain structures with minimal disruption.

Gynecology

  • Laparoscopic Hysterectomy: Reduces recovery time and scarring.

Urology

  • Robotic-Assisted Prostatectomy: Enhances precision and reduces complications.

Recent Breakthroughs

Robotic Surgery

  • AI Integration: Machine learning algorithms assist in real-time decision-making and instrument guidance.
  • Haptic Feedback: New systems provide tactile sensation to surgeons, improving accuracy.

Single-Port Surgery

  • Single Incision Laparoscopic Surgery (SILS): Uses one entry point, further reducing trauma.

Natural Orifice Surgery

  • NOTES (Natural Orifice Transluminal Endoscopic Surgery): Accesses internal organs via natural openings (mouth, anus), eliminating external incisions.

Augmented Reality (AR)

  • Visualization Enhancement: AR overlays anatomical data during surgery, improving orientation and precision.

Recent Study

  • Citation: “Robotic-Assisted Minimally Invasive Surgery: Outcomes and Future Directions” (JAMA Surgery, 2022). This multicenter study found that robotic MIS led to lower complication rates and shorter hospital stays compared to conventional laparoscopic approaches.
