[Pancreatoduodenectomy in Octogenarian Patients and the Need for Standardized Evaluation].

Unlabelled: Pancreatoduodenectomy represents the only curative alternative in patients with periampullary tumors, currently with acceptable morbidity and mortality rates. However, there is little evidence in octogenarian patients.

Aim: To describe the experience of octogenarian patients undergoing pancreatoduodenectomy for tumors of the periampullary area at the Hospital Clínico de la Pontificia Universidad Católica de Chile.

[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.

Robotic transversus abdominis release using HUGO RAS system: our initial experience.

Background: Transversus abdominis release (TAR) is an effective technique for treating large midline and off-midline hernias. Recent studies have demonstrated that robotic TAR (rTAR) is technically feasible and associated with improved outcomes compared to open surgery. There is no published experience to date describing abdominal wall reconstruction using the novel robotic platform HUGO RAS System (Medtronic®).

GALLBLADDER POLYPS: CORRELATION AND AGREEMENT BETWEEN ULTRASONOGRAPHIC AND HISTOPATHOLOGICAL FINDINGS IN A POPULATION WITH HIGH INCIDENCE OF GALLBLADDER CANCER.

Background: Gallbladder polyps are becoming a common finding in ultrasound. The management has to consider the potential risk of malignant lesions.

Aims: The aim of this study was to analyze the ultrasound findings in patients undergoing cholecystectomy due to gallbladder polyps and compare them for histopathological findings (HPs).

Safety of Bariatric Surgery During the Opening Phase After the First Wave of the COVID-19 Pandemic: Experience at an Academic Center.

Introduction: Increased morbimortality in patients with COVID-19 infection who had undergone surgery has raised concerns about bariatric surgery safety during the current COVID-19 pandemic. Currently, there is scarce literature on safety outcomes after bariatric surgery during the COVID-19 pandemic.

Objectives: To determine the risk of symptomatic COVID-19 infection and associated complications during the first 30 days after bariatric surgery.

[Littoral cell angioma of the spleen. Report of one case].

Splenic vascular neoplasms are the most common form of spleen tumors. Among them, littoral cell angioma is rare and it is frequently an incidental finding in imaging studies. It has no specific clinical, laboratory or imaging findings.

[Removal of an infected gastric cyanoacrylate plug. Report of one case].

In patients with actively bleeding gastric varices, the treatment of choice is the endoscopic use of sclerosing agents such as cyanoacrylate. We report a 69-year-old man who, after being treated with cyanoacrylate, suffered from recurrent febrile episodes. After an extensive study and broad-spectrum antibiotic treatment, discarding other presumably infectious focus, the superinfection of the cyanoacrylate plug was suspected, and its surgical removal was decided.

Telemedicine for postoperative follow-up, virtual surgical clinics during COVID-19 pandemic.

Unlabelled: Recent coronavirus outbreak and "stay at home" policies have accelerated the implementation of virtual healthcare. Many surgery departments are implementing telemedicine to enhance remote perioperative care. However, concern still arises regarding the safety of this modality in postoperative follow-up after gastrointestinal surgery.

Bariatric Surgery in Cirrhotic Patients: a Matched Case-Control Study.

Introduction: Laparoscopic bariatric surgery (LBS) in liver end-stage organ disease has been proven to improve organ function and patients' symptoms. A series of LBS in patients with cirrhosis have shown good results in weight loss, but increased risk of complications. Current literature is based on clinical series.
