Survival and Mid-Term Outcomes of On Pump vs. Off Pump Coronary Artery Bypass Grafting: A Propensity Score-Matched Analysis in A First Peruvian Registry.

Introduction: The efficacy and outcomes of on-pump and off-pump coronary artery bypass grafting (CABG) remain uncertain, especially in Latin America. Our study aims to explore survival and shortand mid-term outcomes in the first reported Peruvian registry of patients treated with both techniques.

Methods: This is an observational, analytical, and longitudinal study using a propensity score-matched (PSM) analysis in a single-center retrospective registry of 2280 patients during 2000-2019; 846 patients were analyzed after PSM (on-pump = 423 vs.

Construction and Surgical Training of Coronary Anastomosis on a Low-Cost Portable Simulator: Experience in a Peruvian Multicenter Study.

Introduction: The operating room is no longer the ideal place for early surgica training of cardiothoracic surgery residents, forcing the search for simulation-based learning options. The study's aim was the construction and surgicaltraining of coronary anastomosis in a portable, low-cost, homemade simulator.

Methods: This is an observational, analytical, and multicenter study.

Survival, Short And Long-Term Outcomes Of Open And Endovascular Surgical Repair Of Unruptured Infrarenal Abdominal Aortic Aneurysms.

Introduction: Endovascular Aortic Repair (EVAR) has become the standard management of Unruptured Infrarenal Abdominal Aortic Aneurysm (UIAAA); however, current evidence is limited and uncertain in our environment compared to Open repair. Our study aimed to determine the survival, short and long-term outcomes of EVAR vs. Open in a Peruvian cohort of UIAAA.

[Colonic cancer with infiltration to the abdominal wall: a diagnostic challenge].

We present the case of a 53-year-old woman with a time of illness of 20 months, characterized by pain at the site of surgical intervention for opened cholecystectomy 3 years ago, associated with a presence of a mass in said area, with the following abscess formation and fistulization of food content. Imaging studies revealed a mass dependent of the transverse colon, in contact with stomach and abdominal wall and presenting fistulas to the skin. Said mass was extracted during surgery with anatomopathological result of mucinous colon adenocarcinoma.

[Pre-extensively drug-resistant congenital tuberculosis: case report].

Tuberculosis in infants is a clinical case difficult to diagnose by regular testing which often yield negative results; additionally, the source of transmission is difficult to identify. This work presents the case of a one-month old nursing boy presenting irritability, tachypnea, fever, poor gain weight from birth, and hepatomegaly. Additionally, he had the maternal history of pre-extensively drug- resistant tuberculosis and tuberculoid granulomatosis reaction with positive auramine tincture for acid-alcohol resistant bacilli at histopathology of the placenta.
