AN INTRODUCTION TO LAPAROSCOPIC SURGERY By; Col.Abrar Hussain Zaidi
THE ORIGIN Innate Human Desire – to Be Minimally Harmed / Surgically
This thought makes the foundation of what is now referred to asminimally invasive surgery.
Nomenclature Minimally invasive surgery (MIS), bandaid surgery, keyhole surgery, or pinhole surgery is a modern surgical technique in which: operations are performed through small incisions (usually 0.5-1.5cm) as compared to larger incisions needed in traditional surgical procedures
Nomenclature Scopic surgery Endoscopic surgery. broader term For the use of an endoscope Laparoscopic /Thoracoscopic/others
Nomenclature • Laparoscopic surgery Laparoscopic surgery includes operations within the abdominal or pelvic cavities • Thoracoscopic surgery.[VATS] MIS surgery performed on the thoracic or chest cavity
Other Endoscopic /Scopic surgery • Arthroscopy • Cranioscopy • Endoluminal
HISTORY A physician’s desire to evaluate the inside of a patient's body with limited injury existed as far back asHippocrates (460-375 B.C.). He made reference to examination of the rectum with a speculum.
Phillip Bozzini (1773-1809) The light conductor invention • In 1901 George Kellingexamine the abdominal cavity of dogs • Jacobeus [1901--?] a surgeon from Stockholm, coined the phrases "laparoscopie" and "thoracoscopie". first to publish a series of abdominal and thoracic examination in humans using minimally invasive techniques.
Bertram Berheim from Johns Hopkins in 1911 to perform the first laparoscopy in the United States. • The advent of the insufflator (Kurt Semm), fiberoptics and the rod-lens system (Harold Hopkins)-1958.
First solid state camera in 1982 • 1987 -Phillipe Mouret performed the first laparoscopic cholecystectomy. An ignition for the laparoscopic surgery.
During the past <two decades, a dynamic evolution in Minimally Invasive Surgery has occurred that has no equal in the history of surgery
SPECTRUM The world of MIS has expanded during the last decade to include most surgical fields; • Abdomen and thorax • Brain and heart, • Gynaecology • Orthopaedics
SPECTRUM DIAGNOSTIC THERAPEUTIC
Operative Cholecystectomy Appendicectomy Bowel resection Repair of Prolapse Nephrectomy Bypass Spleenectomy Gynaecological SPECTRUM Diagnostic • TB/Crohn’s • Diverticulitis • Lymphadenopathy • Benign renal disease • Gastric Obstruction • Some Splenic disorders
GROWING SPECTRUM TELEROBOTICS • 1994 --- the introduction of roboticsinto the operating room. • A robotic arm was used to hold the camera replacing the camera operator. • 1996- a surgery was performed with the patient and surgeon in different locations using the Internet - Telesurgery
Future Technologies yet to be introduced - seem boundless. The operating room of tomorrow may not be the same as it is today. Your presence right there may not be necessary [ thanks to telerobotics]
Conceptual debates - ISSUES • Post-operative pain • Recovery / Hospital stay • Visual field for surgeons • Operation time • Cost • Cosmetic outcome • Patient acceptance • The complications
Advantages/ benefits Reduced post operative pain and analgesic requirement Reduced operative trauma Reduced bleeding Faster recovery, discharge and return to work Reduced wound infection, seroma and haematoma Reduced chronic wound pain Less cardiorespiratory complications
Advantages/ benefits • Less ileus from reduced handling • Improved cosmesis • Reduced contamination of theatre staff (Hepatitis and HIV) • Interesting for surgeons • Reduced outpatient/social costs
Advantages/ benefits • Reduced risk of DVT/PE • Reduced incisional hernia rate • Fewer adhesions and less likely to develop obstruction • Immunological benefits • Better visualisation for the surgeon
Disadvantages/ Risks • High risk of co-lateral injury eg Common bile duct in lap cholecystectomy • Bowel/bladder/vascular injury in hernia surgery • Verres needle injury • Diathermy may lead to organ damage eg late cbd stricture • Increased operating time
Disadvantages/ Risks • Increased costs due to theatre time and equipment • Tumour seeding • Poor quality surgery eg cancer resection • Loss of tactile sensation • Long learning curve • Loss of training opportunity eg appendicitis and inguinal hernia • Some surgeons not able to develop skills
THE EQUIPMENT • THE TECHNIQUE • THE TRAINING
The Equipment • Laparoscope/video system • Light source • Insufflator • Diathermy /coagulation:cutting system [+Harmonic ace] • Suction irrigation system • Specialized hand instruments
The Equipment • Laparoscope/video system There are two types: • Telescopic rod lens system, that is connected to a video camera (single chip or three chip) or • A digital laparoscope where the charge-coupled device[CCD] is placed at the end of the laparoscope, eliminateing the rod lens system.
Telescopic rod lens system There are three important structural differences in telescope available in the market. • 6 to18 rod lens system telescopes • 0 to 120 degree telescopes • 1.5 mm to 15 mm of telescopes
Video camera Single chip VS three chip Three primary colours (Red,Blue, Green). In single chip camera all these 3 primary colours are sensed by single chip. In three chip camera there are 3 CCD- Chips for separate capture and processing of 3 primary colours—High resolution
Monitor • No different from the T.V. • Basic principle of image reproduction is horizontal beam scanning on the face of the picture tube.
The existing television systems in use differ according to the country. • The U.S.A uses the NTSC (National Television System Committee) system. • In European countries the PAL (Phase Alternation by Line) system is in use. • French system called SECAM (Sequential color and memory).
Light source A fiber optic cable system connected to a 'cold' light source (halogen or xenon), to illuminate the operative field,
Insufflator The abdomen is insufflated with carbon dioxide gas [pneumoperitomeum] to create a working and viewing space. Elevates the abdominal wall above the internal organs like a dome. Gasless surgery –with mechanical wall elevators
Coagulation & cutting System Diathermy monopolar / bipolarHarmonic
Specialized hand instruments A-ACCESS INSTRUMENTS B-DISSECTING/OPERATING INSTRUMENTS C-RETRIEVAL INSTRUMENTS
Specialized hand instruments 5-10mm diameter instruments • Trocars & Ports---access devices • Graspers • Scissors • Dissectors • Clip applier,Knotting devices,Staplers • Cutting /coagulation – hooks,spatulas,balls,forceps • Irrigation suction tubes • Retrieval instruments
Disposable vs Reusable instruments Conventional vs. Needle scopic /miniaturized instruments—2mm size
