Laparoscopic cholecystectomy complications: a new case report of a right hepatic artery pseudoaneurysm that caused jaundice.

Iatrogenic vascular injuries of the hepatic artery are infrequent and a serious complication of LC. There is no doubt about the many advantages of LC when compared to open cholecystectomy. Despite this, there is an increase in the reported incidence (0.3%-1.0%) of biliary and vascular injuries. Most arterial complications are due to direct injury or diathermy shortening on surgical clips and HAP is one of them. We present a case of a 39-year old male patient who presented with this complication and how it was resolved.

Ileal tubular adenoma as a cause of lower gastrointestinal bleeding in infants.

Lower gastrointestinal bleeding is a common pathology with diverse causes depending on the patients´ age. The most common causes in adults are polyps, neoplasias, diverticular disease and angiodysplasia. In neonates, necrotizing enterocolitis and volvulus, and anal fissures and bowel intussusception in infants. Polyps are reported as a cause of bleeding only in children of preschool age.

Duplicaciones de las vías digestivas / Duplications of digestive tract

Las duplicaciones de las vías digestivas son anomalías congénitas infrecuentes, que se pueden localizar en cualquier parte del tubo digestivo, y son más comunes en los hombres. Hasta en un tercio de los pacientes, se acompañan de otras anomalías congénitas. Se han postulado tres teorías para explicar la causa de las duplicaciones: la de la recanalización de la luz intestinal, la del accidente vascular intrauterino y la de la unión o "hermanamiento" incompleta. Se clasifican en duplicaciones quísticas, cuando se comunican con la luz intestinal normal, y en duplicaciones tubulares, cuando no lo hacen; según algunas series, las primeras corresponden de 70 a 75 % de los casos informados y, las segundas, del 25 al 30 %. Poseen tres características esenciales, que son: estar unidas a cualquier segmento del tubo digestivo y con una irrigación sanguínea común; tener una capa muscular, y poseer un revestimiento epitelial que, generalmente, corresponde a la mucosa del mismo trayecto. Los síntomas más comunes son dolor abdominal inespecífico, náuseas, vómitos, hemorragia gastrointestinal, invaginación, obstrucción, ictericia y pancreatitis. El diagnóstico se basa, especialmente, en estudios imagenológicos, desde la radiografía simple hasta la resonancia magnética, siendo de gran importancia la ecografía prenatal. El tratamiento quirúrgico es la principal opción terapéutica, en la cual se usa cada vez más la vía laparoscópica

Alimentary tract duplications are rare congenital lesions that can occur anywhere in the gastrointestinal tract. Three hypotheses about their etiology had been proposed, The luminal recanalization theory, the intrauterine vascular accident theory, and the abortive twinning theory. According to some series, three quarters of gastrointestinal duplications are cystic with no communication to the adjacent alimentary tract, while the remaining are tubular and may communicate with the intestinal lumen.They have three essential characteristics: they are attached to any segment of the gastrointestinal tract and with the same blood supply, having a muscular layer and possessing an epithelial lining that corresponds generally to the mucosa of the same path. The most common symptoms are nonspecific abdominal pain, nausea, vomiting, gastrointestinal hemorrhage, invagination, obstruction, jaundice and pancreatitis. The diagnosis is based mainly on imaging studies, ranging from simple radiography to nuclear resonance, with prenatal ultrasound being of great importance. Surgical treatment is the main therapeutic option, being increasingly used the laparoscopic route

Successful Endoscopic Management of Late Biliary Cast Syndrome in a Liver Transplant Recipient: A Case Report.

Biliary cast syndrome (BCS) is an unusual complication of liver transplantation (LT). The pathophysiology is not known, and it is thought to develop because of mucosal damage in the bile duct related to obstruction, ischemia, or bacterial infection. It occurs in 2.5-18% of LT patients and is associated with increased graft failure, need for retransplantation, and mortality. Here we report on a case of BCS of late appearance after LT who was successfully treated by endoscopic means.
