Patient Information
In the field of endoscopy several procedures can be carried out. As a patient it is important to understand what exactly happens during such examinations. The purpose of this section is to explain this in simple terms.

To find out more choose one of the procedures below:

Examination of the stomach


Examination of bile duct and pancreas
Examination of the colon

Examination of air passages

Laparoscopic Surgery, also called keyhole surgery (when natural body openings are not used), bandaid surgery, or minimally invasive surgery (MIS), is a surgical technique. Medically, laparoscopic surgery refers only to operations within the abdomen or pelvic cavity. Laparoscopic surgery belongs to the field of endoscopy. consists of a Hopkins rod lens system, that is usually connected to a videocamera- single chip or three chip, a fibre optic cable system connected to a 'cold' light source, halogen or xenon, to illuminate the operative field, inserted through a 5 mm or 10 mm canula to view the operative field. Additional 5- 10 mm thin instruments can be introduced by the surgeon through side ports. Rather than a 20 cm cut as in traditional cholecystectomy, two to five cuts of 5-15 mm will be sufficient to perform a laparoscopic removal of a gallbladder. The abdomen is usually insufflated with carbon dioxide gas to create a working and viewing space.

It is difficult to credit one individual with the pioneering of laparoscopic approach. In 1902 Georg Kelling of Dresden performed the first laparoscopic procedure in dogs and in 1910 Jacobaeus of Sweden reported the first laparoscopic operation in humans. In the ensuing several decades, numerous individuals refined and popularized the approach further, but the field of laparoscopy as a whole remained limited to diagnostic rather than therapeutic procedures, mainly due to lack of adequate technology. It was not untill 1985 when, with the advent of new a specialized computer chip television camera by Circon Corporation, the approach was broadened in scope to include surgical resection of organs such as gall bladder.

The approach is intended to minimize post-operative pain and speed up recovery times, while maintaining an enhanced visual field for surgeons. Due to improved patient outcomes, in the last two decades, laparoscopic surgery has been adopted by various surgical sub-specialties including gastrointestinal surgery, gyneacologic surgery and urology. Based on numerous prospective randomized controlled trials, the approach has proven to be benefitial in reducing post-operative morbidites such as wound infections and incisional hernias (especially in morbidly obese patients), and is now deemed safe when applied to surgery for cancers such as cancer of colon.

In some cases the pain caused by the carbon dioxide left in the peritoneal cavity at the termination of the procedure is severe and painkillers may not be very effective. The restricted vision, difficult handling of the instruments (hand-eye coordination), lack of tactile perception and the limited working area can increase the possibility of damage to surrounding organs and vessels, either accidentally or through the difficulty of procedures. For these reasons, minimally invasive surgery has emerged as a competitive new sub-specialty within various fields of surgery. Surgical residents who wish to focus on this area of surgery, gain additional training during one or two years of fellowship after completing their basic surgical residency.

The first transatlantic surgery (Lindbergh Operation) ever performed was a laparoscopic gallbladder removal.

Endoscopy & Pancreatic-Biliary Disorders

Endoscopes are flexible tubes that can be passed through the mouth or rectum, and allow direct viewing of the surfaces of the esophagus (food pipe), stomach, intestine and colon. Endoscopic examinations allow physicians to diagnose and treat a variety of intestinal disorders, including abdominal pain, vomiting, and bleeding from the intestinal tract. In addition, benign growths of the colon which can be precursors of colon cancer may be detected and removed. Special adaptations of the endoscope allow stones to be removed from the bile duct (drainage tube for digestive juices of the liver and gallbladder) and pancreas. A new technique, known as endoscopic ultrasound, allows very high detailed views of the gastrointestinal tract, as well as neighboring structures such as the pancreas.

Pancreatic disease may manifest itself in many ways, including painful masses, acute intermittent attacks of pain, or chronic inability to digest food due to insufficient production of pancreatic digestive enzymes.
