    Single Port Laparoscopic Gastrostomy: description of a technique and initial experience.
    Acta Gastroenterol Latinoam 2015 12;45(4):280-7
    Introduction: Since the first classic descriptions of surgical gastrostomies for feeding by supra-umbilical medial incisions, patients were operated under general anesthesia, with prolonged time of surgery; these were patients in poor health status, undernourished due to inadequate intake or to neurological or tumor involvement, with prolonged hospitalization, both for the recovery of the intestinal motility as well as for the recovery of post-surgical wounds. Therefore, we describe a new minimally invasive technique as an alternative to the percutaneous or endoscopic gastrostomy, in patients where we are not allowed to place a nasogastric tube to insufflate the stomach. This is mostly seen in patients with tumors, which cause obstruction. Read More

    Pancreatic polypeptide: a review of its involvement in neuro-endocrine reflexes, islet-acinar interactions and ethanol-evoked physiopatologic pancreatic gland changes.
    Acta Gastroenterol Latinoam 2015 Jun;45(2):155-64
    prevents, in pancreocytes, the evolving of a "supramaximalecbolic-stimulation" process. The PP involvement as a modulating agent of pancreon's reactivity is reflected by the progressive increment of its plasma values in the first week of an evolving AP episode. In the AP associated to a large meal, an overpowering of the pancreon's brake might have a pivotal role. Read More

    Hemobilia is defined as the presence of blood in the biliary tree characterized by the triad: jaundice, right hypochondrium pain (RH) and upper gastrointestinal bleeding (UGB). Among the etiologies highlighted in order of frequency there are: liver trauma (accidental and iatrogenic), inflammatory causes (acute and chronic cholecystitis), infections (cholangitis, liver abscesses, parasitic infections) and vascular diseases (aneurysms, vasculitis, arteriovenous malformations). There exist many complementary tests for the diagnosis of hemobilia, such as imaging (abdominal ultrasound, CT scan, angio CT), videoendoscopy, endoscopic retrograde cholangiopancreatography and angiography, the latter being considered the diagnostic tool and therapeutic modality of choice.

    Acta Gastroenterol Latinoam 2015 Jun;45(2):110-6
    Recommendations for Hepatitis C screening based on risk factorsfor transmission proved to be ineffcient. Accordingly, the CDC recommended to screen all American individuals born between 1945-1965, based on data from population prevalence of infection. The effectiveness of implementing these recommendations in other contexts and/or populations can be estimated, in principle, knowing the age distribution of infected individuals. Read More

    One of the greatest achievements in gastroenterology and surgery of the last 50 years has been the capability to transplant different abdominal organs of the digestive system separately or as a whole. The complexity of the intestinal transplantation demands a multidisciplinary team engaged in the management of patients with intestinal failure responsible for defining the need for nutritional support, rehabilitation, or intestinal transplantation. This team should include a basic research area to provide answers to unresolved clinical problems. Read More
