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.

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.

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®).

Article Synopsis
  • Juvenile myasthenia gravis (JMG) is an autoimmune disorder affecting muscle strength in individuals under 19, with thymectomy showing potential for improved remission alongside medication.
  • A study involving six pediatric patients aged 2 to 14 who underwent video-assisted thoracoscopic (VATS) thymectomy revealed no surgical complications, with an average hospital stay of 2 days.
  • Post-surgery results indicated that three patients were symptom-free without medication, while others experienced reduced corticosteroid needs, although one patient required additional hospitalization due to a crisis.

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.

Article Synopsis
  • Patients undergoing surgery with perioperative COVID-19 infections face significantly higher risks of mortality and major complications compared to those without the virus.
  • A study observed a 30-day mortality rate of 12.8% in COVID-19 patients versus 1.4% in non-infected ones, alongside increased rates of surgical and respiratory complications.
  • The findings suggest that elective surgeries should be limited to essential cases to reduce avoidable health risks during the ongoing 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.

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.
