IS THE ANATOMICAL SEQUENCE OF GASTRIC AND BILIARY ANASTOMOSIS IN THE PANCREATODUODENECTOMY RECONSTRUCTION THE CAUSE OF AN INCREASE IN THE INCIDENCE OF CHOLANGITIS? A TECHNICAL VARIANT PRESENTATION AND INITIAL RESULTS.

Background: Several methods have been proposed for the reconstruction of digestive transit after pancreatoduodenectomy. Biliary anastomosis positioned before gastric anastomosis helps reduce postoperative reflux and cholangitis.

Aims: The objective of this study was to present the anatomical sequence of gastric and biliary continuity after pancreatoduodenectomy in patients with pancreatic tumor and to evaluate the short- and long-term results in an initial series of cases.

Open versus laparoscopic hepatectomies within an ERAS (Enhanced Recovery After Surgery) program. Are there differences?

Background: Laparoscopic procedures have gained popularity because they favor a faster recovery. In the same way, the establishment of an enhanced recovery after surgery (ERAS) program in major abdominal surgery has shortened the hospital stay. There are several studies that report the results on ERAS programs applied to open or laparoscopic hepatectomies or comparing one of them with the classic approach but few have compared the results between both within an ERAS program.

[Metástasis hepáticas sincrónicas de cáncer colorrectal. ¿Resección simultánea o diferida?].

IntroducciÓn: El 20-40% de las metástasis hepáticas de origen colorrectal son de tipo sincrónico. Actualmente existen tres estrategias quirúrgicas; dos de ellas proponen resecciones diferidas, y la otra, la resección simultánea.

Objetivo: evaluar los resultados a corto y largo plazo de las resecciones simultáneas.

[Not Available].

Surgical injury of the biliary tract have increased in the laparoscopic cholecystectomy era, anatomic variants of the biliary ducts, mainly the type F, is likely to receive this kind of injury. Cholangiography helps to prevent such complications, so, we recommended the execution of this procedure in a routine way. Treatment usually is complex and requires trained surgeons.

[Liver resections as radical surgery for hepatic hydatidosis: results in 50 patients].

Introduction: Among several regions in the world hepatic hydatidosis can be considered endemic. Currently there are many available treatments for this disease, been surgery the most effective one. Surgical procedures can be divided in two main groups, radical and non-radical procedures.

[Hilar cholangiocarcinoma: The number of positive nodes and positive node/total node ratio is a significant prognostic factor for survival].

Introduction: Surgical treatment of hilar cholangiocarcinoma remains a challenge. Multiple prognostic factors have been proposed. The number of positive nodes and the ratio between positive lymph node and total lymph node (G+/Gt) are considered by some authors as the most important factor.

Laparoscopic approach to liver hydatidosis: initial experience.

Introduction: Hepatic hydatidosis is a pathology that has a worldwide distribution, and is frequent in some rural areas in Argentina. Surgical treatment still offers the best results. The laparoscopic approach is controversial because of lack of experience with this technique.

Intestinal intussusception in adults: tomographic findings and report of two cases.

Intestinal intussusception is infrequent in adults. Unlike what happens in kids, it shows a demonstrable etiology in most cases: polyps, lipomas, hamartomas, malignancies, etc. Among diagnostic methods, CT scan is the study that yields the best results for the diagnosis, giving forth pathognomonic signs and favoring therapeutic decision-making.

Preparation of a three-dimensional extracellular matrix by decellularization of rabbit livers.

Introduction: the availability of transplantable livers is not sufficient to fulfill the current demand for grafts, with the search for therapeutic alternatives having generated different lines of research, one of which is the use of decellularized three-dimensional biological matrices and subsequent cell seeding to obtain a functional organ.

Objective: to produce a decellularization protocol from rabbit liver to generate a three-dimensional matrix.

Methods: a combination of physical, chemical (Triton X-100 and SDS) and enzymatic agents to decellularize rabbit livers was used.

[Digestive bleeding and acute abdomen caused by jejunal diverticulosis. Case report].

We present a patient with acute abdomen and digestive bleeding caused by jejunal diverticulosis. Jejunal diverticulosis, mainly asymptomatic, when is symptomatic have a wide clinical spectrum, ranging from chronic anemic syndrome to acute abdomen. In this communication, we reviewed the clinical presentation, the pathogenesis and the treatment this infrequent pathology.

[Spontaneous esophago-pleural fistula secondary to candidiasis in a patient with human immunodeficiency virus infection. An infrequent complication of esophageal moniliasis].

Several nosologic conditions may affect the esophagus and cause fistulas communicating this organ with the respiratory system. Rarely, infections cause perforation and further fistula to the bronchial tree, lungs or pleural space. We present the rare case of an HIV-infected patient with related spontaneous esophago-pleural fistula related to Candida infection.
