Más tarde, Philip Physick la usó para realizar un lavado gástrico, y a mediados del siglo XIX, el cirujano francés Sedillot descri-bió la primera gastrostomía quirúrgica. El 18 de septiembre de 1884, en Annals of Surgery, Fenwick dio a conocer una técnica tendiente a reducir el acceso transparietal para realizar una gas-trostomía, y que utilizó en un paciente con un tumor de laringe y fauces, quien evolucionó con desnutrición debido a la incapacidad de ingerir por vía oral. Desde entonces, se publicaron numerosas variantes para la colocación de un tubo en la luz del aparato digestivo con fines de descompresión o alimen-tación.

La cirugía laparoscópica es una técnica mínimamente invasiva, evita las grandes incisiones abdominales. Esto posibilita un posoperatorio mucho más rápido, confortable, con menor dolor y una recuperación más rápida, incluyen-do una reinserción laboral más temprana. Se utilizan monitores de alta resolución donde el cirujano y su equipo pue-den ver las imágenes captadas por una endocámara, y los procedimientos se realizan mediante la introducción de las diferentes pinzas a través de los tro-cares.

Objective: To evaluate the prevalence of gallbladder stones in Buenos Aires. Design: Observational, descriptive, cross section. Setting: Public Hospital tertiary care on gastrointestinal surgery. Material and Methods: Between July 2010 and March 2011, 1032 volunteers were included. A Hepatopancreatobili- ary ultrasound was performed and also a questionnaire was filled in order to identify the volunteer's past medical history. The prevalence of gallbladder stones and the eventual risk factors were studied Results: From the total of 1032 vounteers, 493 were males (47.8%) and 539 females (52.2%) older than 20 years. The average of age was 45.8 ± 16.7. The prevalence of gallbladder stones was 21.6% (n = 223), 15.1% (n = 156) had stones at the moment of the study while 6.5% ( n = 66) had a cholecys...

Summary
Background. Cholelithiasis is an important cause of morbidity
in the world and it varies significantly depending on
the region of study. Objective. To assess the prevalence of
cholelithiasis in Buenos Aires. Material and methods. This
is a cross-sectional, descriptive, observational study performed
in a public hospital with tertiary care in Gastrointestinal
Surgery. From July 2010 to December 2011, 1,875 healthy
volunteers who underwent liver, gallbladder and pancreas
ultrasound imaging were included and a questionnaire containing
the individual’s medical history was administered.
The presence of cholelithiasis and its eventual risk factors
were studied. Results. Of 1,875 individuals, 866 were males
(46.2%) and 1,009 females (53.8%), older than 20 years
old with an average age of 46.1 + 16.7 years. Cholelithiasis
was found in 410 inidviduals (21.9%); 285 (15.2%)
diagnosed at the time of the study and 125 (6.7%) who had
already undergone a cholecystectomy due to gallstones. Conclusions.
The prevalence of cholelithiasis in Buenos Aires,
capital city of Argentina, is 21.9%. A significant association
was found between cholelithiasis and female gender, age,
body mass index, history of colic pain, family history of cholelithiasis,
smoking, fatty liver and number of pregnancies.
Key words. Cholelithiasis, prevalence, risk factors.

Nevertheless, their role in the human gastrointestinal tract, where their action is essential for the reabsorption and secretion of water and electrolytes, is still unclear. The purpose of the present study was to investigate the structure and function of water channels expressed in the human colon. A cDNA fragment of about 420 bp with a 98% identity to human AQP3 was amplified from human stomach, small intestine and colon by reverse transcription polymerase chain reaction (RT-PCR) and a transcript of 2.2 kb was expressed more abundantly in colon than in jejunum, ileum and stomach as indicated by Northern blots. Expression of mRNA from the colon of adults and children but not from other gastrointestinal regions in Xenopus oocytes enhanced the osmotic water permeability, and the urea and glycerol transport in a manner sensitive to an antisense AQP3 oligonucleotide, indicating the presence of functional AQP3. Immunocytochemistry and immunofluorescence studies in human colon revealed that the AQP3 protein is restricted to the villus epithelial cells. The immunostaining within these cells was more intense in the apical than in the basolateral membranes. The presence of AQP3 in villus epithelial cells suggests that AQP3 is implicated in water absorption across human colonic surface cells.

The incidence of vascular asymptomatic injuries of the hepatic right artery associated with injuries of the biliary tract is not despicable and the reports in the literature are scarce. The aim of this work is to evaluate the frequency of asymptomatic injuries of the hepatic right artery associated with injuries of the biliary tract and its relation with different factors. Digital angiography was performed in 39 patients with a history of injuries in the biliary tract, finding injuries of the hepatic right artery in 33.3 % of the cases. We believe that it is important to know the vascular anatomy of the hepatic confluence in patients with distal injuries of the biliary tract or with precedents of complex surgeries due to injuries of the biliary tract, because it could determine the following treatment.
