Article Synopsis
  • Minimally invasive techniques, including robotic and laparoscopic surgery, are gaining traction in hepatobiliary surgery due to improved short-term outcomes compared to traditional open surgery.
  • These methods are associated with reduced blood loss, shorter hospital stays, and similar oncologic results, making them a viable option for various liver-related surgeries.
  • While robotic surgery shows advantages like less bleeding and a shorter learning curve, further research is needed on its cost-effectiveness and the development of specialized training programs.

Minimally invasive adrenalectomy has become the main treatment modality for most adrenal lesions. Both laparoscopic transabdominal and retroperitoneoscopic approaches are safe and feasible options, each with respective advantages, including better surgical outcomes, fewer complications, and faster recovery over open adrenalectomy. While open surgery remains a valid modality in treatment of adrenocortical cancer in the presence of some findings such as invasion, robotic platforms, and minimally invasive surgery have gained popularity as technology continues to evolve.

Objective: Cystic echinococcosis (CE) is one of the most common zoonotic diseases worldwide. Diagnosis of CE is predominantly based on imaging techniques and serological tests are used in cases of non-characteristic imaging findings as diagnostic reference. However, serological test results cannot be completely reliable as they are affected by multi-factors.

Immunosuppressive therapy is a double-edged sword and causes a risk for some complications, such as opportunistic infections and posttransplant lymphoproliferative disease. The most likely risk factors for posttransplant lymphoproliferative disease are Epstein-Barr virus serology mismatch, prolonged and high viral load for Epstein-Barr virus, higher doses of immunosuppressive therapy, and cytomegalovirus infection. Transplant recipients who are seropositive for Epstein-Barr virus show a lower risk for posttransplant lymphoproliferative disease than seronegative recipients.

Guidelines include the recommendations of experts from various specialties within a topic in consideration of data specific to each country. However, to date there has not been a guideline standardizing the nomenclature and offering recommendations for intra-abdominal infections (IAIs) in Turkey. This is mainly due to the paucity of laboratory studies regarding the clinical diagnosis and treatment of IAIs or the sensitivity of microorganisms isolated from patients with IAIs.
