History of SIED

At the First Congress of Gastroenterology held in Washington in 1958, Hirschowitz introduced fibroscopes and since then gastroscopy has become a diagnostic tool of excellence, displacing rigid cold-light endoscopes that were used to explore the esophagus and rectosigmoid. It is notable that at the World Congress ofGastroenterology held in Bangkok in 2002, Hirschowitz himself gave a keynote lecture where he showed the beginnings of fiber optic endoscopy and some of the advances made later in digestive endoscopy.

The continuous improvement of the instruments made it possible to easily and with great diagnostic certainty explore the upper gastrointestinal tract and the colon. The Hirschowitz gastrofibroscope was exported to Japan in 1963 and a group led by Drs. Tsuneoka, Kasugai and Takemoto managed to improve it by allowing biopsies and samples for cytology obtained under direct vision, thus incorporating histopathological diagnosis to that of simple endoscopic observation. .

These instruments were in the field of University and Clinical Services, probably initially in countries more related to the major world centers, but gradually they spread throughout the Latin American region until the great explosion and spread of fibroendoscopy and later videoendoscopy.

One of the authors of this article had the opportunity to receive, together with Dr. Jaime Klinger, the teachings of Kunio Takagi at the “Cancer Institute Hospital in Tokyo” in the early 1970s. Shortly after Dr. Takagi returned to the country He visited Chile and left in the form of a “loan for one year”, a flexible Machida brand endoscope, which already included the channel for the biopsy. Dr. Takagi recommended not to take biopsies until after a long time, since we could err in our diagnosis when obtaining falsely negative samples or suffer some complication in taking them due to our inexperience.

We dissented and immediately started taking biopsies, achieving that same year the first cases of incipient gastric cancer diagnosed endoscopically, corroborated by the biopsy and then by the study of the operative specimen. It is good to remember what those initial steps were like: Dr. Klinger used the Machida endoscope one week at Hospital del Salvador and Dr. Llorens one week at Hospital San Borja. This alternation allowed to benefit many patients in both hospitals and constitutes a good example of cooperation, leaving a note of deserved thanks to Dr. Kunio Takagi, who soon, like many of our teachers in Japan, verified the fruits obtained from his teachings. and he put aside his apprehensions that in those years could be justified.

The Gastrochamber invented in Japan by Dr. T. Uji in 1950 was little used because it caused some discomfort during endoscopic exploration because it was somewhat thick. I used a monochrome photographic roll. The gastrocamera was blind, the endoscopist taking photographs in predetermined positions that allowed almost all of the stomach to be covered with its images, although the first models had some difficulty in obtaining adequate documentation of the cardia, posterior aspect and minor curvature. The model called GT-V was introduced in 1960 as the tube was thinner (8.5 mm) and more flexible than previous models and was widely used in that country. The tiny 5mm wide roll of film capable of taking 32 color exposures was placed at the tip of the apparatus. Then the GTF Gastrofibroscope was designed that used the same photographic roll, but allowed the endoscopist to visualize throughout the procedure, selecting those areas that wanted to document in greater detail. Among the pioneers in its use in Latin America, we can highlight Dr. Akira Nakadaira from Brazil and Dr. Hernán Espejo from Peru. These instruments did not have a channel for taking biopsies, so their use gradually decreased and remained in force only in some programs for mass detection of gastric cancer. Akira Nakadaira from Brazil and Dr. Hernán Espejo from Peru. These instruments did not have a channel for taking biopsies, so their use gradually decreased and remained in force only in some programs for mass detection of gastric cancer. Akira Nakadaira from Brazil and Dr. Hernán Espejo from Peru. These instruments did not have a channel for taking biopsies, so their use gradually decreased and remained in force only in some programs for mass detection of gastric cancer.

On September 6, 1973, during the XIII Pan American Gastroenterology Congress in Buenos Aires, the Inter-American Society for Digestive Endoscopy (SIED) was founded. The authorities of the Congress, especially Drs. Marcos Meeroff and Horacio Rubio, considered the opportunity propitious because a large number of gastroenterologists were already dedicated preferentially and, moreover, to endoscopy.

Dr. Horacio Rubio was nominated President of SIED. Its first Board of Directors was made up of, among others, Drs. José Martins Job from Brazil, José Ramírez Degollado from Mexico, Henry Colcher from USA, Marcos Matos-Villalobos from Venezuela, Arecio Peñaloza from Colombia, Raimundo Llanios from Cuba and Pedro Llorens from Chile. – It also had the collaboration of Dr. Francisco Vilardell, at that time, President of the European Organization of Digestive Endoscopy and Secretary of the World Organization of Gastroenterology (OMGE).

We remember Dr. Horacio Rubio as one of the most outstanding gastroenterologists in Latin America. The following gastroenterologists participated in the constituent meeting of SIED:

Argentina:Jorge Landriel Márquez and Horacio Rubio
Bolivia:Fernando Patiño
Colombia:Jaime Campos Garrido, Vicente Albán Muñoz, Mario Orozco and Arecio Peñaloza
Cuba:Julián Alvarez and Raimundo LLanio
Chile:Pedro Llorens Sabaté
Ecuador:Fausto Pazmiño Carrasco
USA.:Henry Colcher
Mexico:José Ramírez Degollado
Peru:Ernesto Castillo Lindley and Alberto Ramírez Ramos
Dominican rep:Eduardo Alvarez and Aulio Brea
Uruguay:Emilio Pérez Fernández
Venezuela:Marcos Matos Villalobos and Hans Romer

Since then, the work carried out by SIED has been fruitful and numerous endoscopists have participated prominently, either exercising high positions in its management or in the organization of its scientific events.

Dr. Arecio Peñaloza kept the SIED Bulletin in force for more than 20 years, which allowed the sharing of relevant information among Latin American experts. In addition to the advances, it included social notes thus humanizing scientific information. His effort has been commendable as he dedicated many hours of work and knew how to print on those pages much of his brilliant personality. In 1997 Dr. Peñaloza himself wrote an Editorial in “Latin American Gastroenterology” with a summary of the history of the SIED, which constitutes a document of great value and provides many valuable antecedents that for reasons of space we do not put here.

The last years have been one of sustained growth of the SIED. The Punta del Este congress with an attendance of more than 1000 congressmen and led by Dr. Daniel Taullaurd from Uruguay was an example of organization and friendship. During his tenure SIED was integrated as part of the ASGE International Committee and ties of friendship and cooperation with AIGE were strengthened. In 2005 a small meeting was held in Montreal, Canada within the framework of the World Congress of Gastroenterology and Endoscopy. In agreement with AIGE, it was arranged that the efforts of both boards would last only one year, with Dr. Ismael Maguilnik from Brazil holding the position of SIED. In November 2006, the wonderful port of Cancun, Mexico, hosted the XVII Pan American Endoscopy Congress led by Dr. Angélica Hernández Guerrero, President of the Mexican Association of Gastrointestinal Endoscopy and Dr. Juan Miguel Abdo Francis, President Elect of SIED taking effect the transmission of a Live Course from Chicago and the Cancer Institute of Mexico City simultaneously. It is noteworthy the collaboration of Dr. Irving Waxman, President of the ASGE International Committee for its success.

During the 2006-2008 term, Puerto Rico was accepted through the Puerto Rican Society of Therapeutic Endoscopy (SPET) as a partner and the Endoscopic Ultrasound chapter was created, endorsed by many subsidiary companies. The SIED website was modified and continued as a member of the ASGE International Committee, among other actions.

The XVIII Pan American Endoscopy Congress in Casa Piedra, Santiago de Chile under the direction of Drs. Roque Sáenz and Claudio Navarrete, is the culmination of the Presidency of Dr. Juan Miguel Abdo Francis. The SIED course, the SIED symposium and the OMED Endoscopy Directors workshop remain for the history of the Inter-American Society of Digestive Endoscopy.

From now on, all efforts are aimed at the realization of the 2010 Congress in Guayaquil under the Presidency of Dr. Carlos Robles Jara from Ecuador where the endoscopy of America will meet again at its most important academic festival.
