Uterus transplantation in a sheep model: novel surgical technique with long-term survival and uterus vitality. First case series in Argentina.

Objective: To develop a sheep autologous uterus transplantation (UT) program with an innovative surgical technique and assess long term uterus vitality and animal survival.

Methods: A novel surgical technique consisting of the procurement of the complete uterus and the two ovaries, back table vascular reconstruction, and subsequent implantation in the same animal, performing only two arterial and two venous anastomoses.

Results: Four autologous transplantations were performed; anesthesia and surgery were well tolerated by all the animals without complications.

Preservation fluid cultures. Clinical significance in liver transplantation.

The aim of this study was to determine the incidence of preservation fluids (PF) bacterial positive cultures, identify the germs involved, determine their correlation with infections in recipients during the postoperative period and compare outcomes in terms of morbidity, hospital stay and both patient and graft survival. We describe incidence and etiology of germs developed in PF cultures in our series and evaluate its impact on recipients. A prospective study in deceased donor liver transplants (LT) recipients was carried out from January 2014 to December 2017.

Solid pseudopapilar neoplasm of the pancreas.

Solid pseudopapillary tumor of the pancreas is a rare entity, more frequent in women between the 2 and 4 decades. The diagnosis is usually incidental and it can be reached by computed tomography or magnetic resonance imaging. Subsequent pathological confirmation is necessary for an adequate treatment.

Mielolipoma retroperitoneal perirrenal: reporte de un caso.

El mielolipoma es un tumor benigno de baja incidencia cuya localización más frecuente son las glándulas suprarrenales. Histológicamente se caracteriza por células con precursores mieloides y eritroides mezcladas con tejido adiposo maduro. El diagnóstico en general es incidental en una prueba de imagen.

Efficacy and reproducibility of lymphatics mapping technique with sentinel lymph node biopsy in melanoma.

Introduction: The study of the Sentinel Lymph Node (SLN) in Melanoma is a procedure that aims the identification of the first node to which the affected cutaneous sector drains in order to avoid unnecessary lymphadenectomies. The present study documents the frequency of identification of SLN; the relationship between positive SLN (PSLN) and recurrence, between the Breslow index (BI) and PSLN, and between BI and disease recurrence.

Method: We analyzed the records of 148 patients with melanoma stages I and II undergoing lymphatic mapping and GC biopsy from 1999 to 2017 in a third level institution in Córdoba, Argentina.

Risk factors for surgical site infection in colon surgery in our population.

Background: Surgical site infection (SSI) is the most common nosocomial infection in surgical patients with an incidence that varies between 5-30%.

Objective: Identify the risk factors for SSI in colonic surgery in our population. The secondary aims are to determine the incidence and type of SSI, as well as the incidence of an anastomotic leakage (AL).

[Hepatic Parasitosis: Atypical presentation].

Benign solid liver tumors are composed by a heterogeneous group of lesions. Hepatic parasitosis is an infrequent etiological cause of benign solid liver tumors. Objective.

Chagas disease and liver transplantation: Experience in Argentina using real-time quantitative PCR for early detection and treatment.

Background: Chagas disease (CD) is an endemic zoonosis that occurs in Latin America and is caused by the parasite Trypanosoma cruzi. Early detection of T. cruzi in liver transplant recipients at risk may avoid complications from CD.

[Laparoscopic atypical gastrectomy in the treatment of gastric GIST. Short-term and medium-term outcomes].

Gastrointestinal stromal tumors are the most common mesenchymal neoplasms of the gastrointestinal tract. Recently, many studies have addressed the laparoscopic management of these tumors. The aim of this study was to evaluate the safety and efficacy of laparoscopic atypical gastrectomy in the resolution of these neoplasms.

Esophageal metalic stent migration. Case report of a dislodged stent retrieval.

Background: Metallic stent placing is the first choice in the treatment of malign or benign strictures of the esophagus. Stent migration is a well-known complication of this procedure. We report a case of stent migration in which surgical laparoscopic intervention was used to retrieve it.

[Celiac trunk compression syndrome by the median arcuate ligament. Laparoscopic approach].

Median arcuate ligament syndrome (MALS), or celiac trunk compression syndrome, is caused by extrinsic compression of median arcuate ligament, prominent fibrous bands and periaortic nodal tissue. In many cases is asymptomatic, but it may manifests with symptoms such as postprandial abdominal pain or during exercise, nauseas, vomiting and weight loss. Trough less invasive diagnostic techniques, such as doppler ultrasound for screening and preoperative angiotomograhpy, it is possible to obtain good results, comparable to those with arteriography.

[Morgagni's hernia: Report of a case treated by videolaparoscopy].

Morgagni's hernia is a rare congenital disorder, usually asymptomatic, but may cause respiratory or gastrointestinal symptoms. We reviewed the clinical findings of a patient with a Morgagni's hernia, diagnosed and treated in our department. The Morgagni's hernia caused various symptoms in our patient and surgery was performed via laparoscopy.

[Omental hernia through esophageal hiatus simulates mediastinal lipomatous tumor].

Omental hernia through the esophageal hiatus is extemely infrequent. Paraesophageal hiatal hernia with omentum in the herniary sac mimics a mediastinal lipomatous tumor and differential diagnosis should be made. This diagnosis requires experience and knowledge of the differences between these two pathologies.
