Radical Laparoscopic Pericystectomy of a Giant Hepatic Hydatid Cyst.

Hydatidosis is an endemic zoonotic disease with an uneven geographical distribution due to the varying abundance of its intermediate hosts, primarily cattle, and sheep in different regions, leading to a higher concentration of cases in livestock areas. Despite advancements in medical treatment and interventional radiology, surgery remains the treatment of choice for patients with hepatic hydatid cysts (HHC). Over the past decade, laparoscopic management of HHC has gained popularity; however, controversies persist regarding optimal patient selection, surgical techniques, and follow-up protocols.

[Portal vein embolization prior to major hepatectomy: A multidisciplinary approach for advanced liver tumors in Chile].

Background: One of the main limitations to achieving a complete tumor resection in patients with technically resectable liver tumors is the presence of a small future liver remnant (FLR). Portal vein embolization (PVE) allows hypertrophy of the non-embolized lobe, reducing the risk of postoperative liver failure.

Aim: To describe the experience of portal embolization prior to hepatectomy and its effectiveness in converting advanced unresectable liver tumors into resectable tumors.

Type I choledochal cyst. Total laparoscopic resection and Roux-en-Y reconstruction to two separated ducts.

A choledochal cyst is a rare condition that requires surgical treatment to prevent complications, such as obstructive jaundice, cyst rupture, cholangitis, and the risk of malignancy. Complete cyst excision is considered the best option, as it reduces the risk of inflammation and the development of cholangiocarcinoma. Therefore, cholecystectomy and complete cyst resection followed by reconstruction with a Roux-en-Y hepaticojejunostomy is the treatment of choice.

Portosystemic shunt surgery for severe portal hypertension due to portal thrombosis after bariatric surgery.

Portal vein thrombosis is a rare complication after laparoscopic sleeve gastrectomy, a widely performed bariatric surgery procedure. Occasionally, the development of portal vein thrombosis can progress to more severe conditions, including portal hypertension and cavernomatosis, thereby presenting a complex and challenging clinical scenario. The management of such complications often requires careful consideration; however, surgical intervention in the form of a splenorenal shunt is an exceptional indication.

A new approach for the acquisition of trauma surgical skills: an OSCE type of simulation training program.

Background: Worldwide, trauma-related deaths are one of the main causes of mortality. Appropriate surgical treatment is crucial to prevent mortality, however, in the past decade, general surgery residents' exposure to trauma cases has decreased, particularly since the COVID-19 pandemic. In this context, accessible simulation-based training scenarios are essential.

Validity Argument for a Simulation-Based Objective Structured Clinical Examination Scenario for Evaluation of Surgical Skills in Trauma.

Background: Trauma is one of the main causes of death globally, and appropriate surgical care is crucial to impact mortality. However, resident-performed trauma cases have diminished in the last 10 years. Simulation-based tools have proven to be effective to evaluate practical skills in a variety of settings.

SELF-CONFIDENCE ON ACQUIRED SURGICAL SKILLS TO DEAL WITH SEVERE TRAUMA PATIENTS IN RECENTLY GRADUATED SURGEONS.

Background: Level of competence by procedure. Trauma is one of the leading causes of death in the world and proper surgical care is critical to impact mortality. In Chile, trauma associated death ranks first as mortality cause in population between 20 and 59 years old.

Severe case of post cholecystectomy vasculobiliary injury successfully treated by right hepatectomy with a jump graft to the remaining left hepatic lobe.

Vasculobiliary injuries (VBI) caused by cholecystectomies are infrequent but extremely serious. We report a case of a severe VBI successfully treated at our center. A 22-year-old woman underwent an open cholecystectomy as treatment for acute cholecystitis and bile duct stones.

Smartphone application supplements laparoscopic training through simulation by reducing the need for feedback from expert tutors.

Background: Simulation training is a validated, highly effective tool for learning laparoscopy. Feedback plays a crucial role in motor skills training. We present an app to guide students during advanced laparoscopy simulation training and evaluate its effect on training.

BRAZILIAN CONSENSUS ON INCIDENTAL GALLBLADDER CARCINOMA.

Background: Incidental gallbladder cancer is defined as a cancer discovered by histological examination after cholecystectomy. It is a potentially curable disease. However, some questions related to their management remain controversial and a defined strategy is associated with better prognosis.
