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

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.
