Background: At least 20% of the future liver remnant must function properly after liver tumor resection to avoid post-hepatectomy liver failure (PHLF). [Tc]Tc-mebrofenin scintigraphy and SPECT are unique noninvasive, quantitative methods for evaluating liver function via hepatocellular bilirubin clearance.

Aim: To evaluate the value of dynamic [Tc]Tc-mebrofenin SPECT/CT parameters for predicting clinically relevant PHLF according to the ISGLS criteria.

Different applications of near-infrared fluorescence-guided surgery are very promising, and techniques that help surgeons in intraoperative guidance have been developed, thereby bridging the gap between preoperative imaging and intraoperative visualization and palpation. Thus, these techniques are advantageous in terms of being faster, safer, less invasive, and cheaper. There are a few fluorescent dyes available, but the most commonly used dye is indocyanine green.

Systemic inflammation (SI) is a response of the immune system to infectious or non-infectious injuries that defends the body homeostasis. Every surgical intervention triggers SI, the level of which depends on the extent of damage caused by the surgery. During the first few hours after the damage, the innate or natural immunity, involving neutrophils, macrophages, and natural killer cells, plays a main role in the defense mechanism, but thereafter the adaptive immune response ensues.

Background: Laboratory skills training is an essential step before conducting minimally invasive surgery in clinical practice. Our main aim was to develop an animal model for training in clinically highly challenging laparoscopic duodenal atresia repair that could be useful in establishing a minimum number of repetitions to indicate safe performance of similar interventions on humans.

Materials And Methods: A rabbit model of laparoscopic duodenum atresia surgery involving a diamond-shaped duodeno-duodenostomy was designed.

Castleman disease is a rare lymphoproliferative disease the exact cause of which is not known. The diagnosis is based on the adequate histological examination. While in the unifocal form, the disease most commonly affects the chest, and symptoms may resolve as a result of intact excision of the tumour; other treatment methods may be performed in addition to or instead of surgical incision in the case of the multifocal form.

Although the majority of lung adenocarcinomas show mixed pattern, only the predominant component is taken into account according to the novel classification. We evaluated the proportion of different patterns and their impact on overall survival (OS) and disease-free survival (DFS). Patterns were recorded according to predominance and their proportions were rated and calculated by objective area measuring on digitalized, annotated slides of resected stage I lung adenocarcinomas.

Aim: Due to the emerging experience in VATS (video assisted thoracic surgery) lobectomies, in some centers the so called "non-intubated" VATS lobectomies (NITS - non-intubated thoracic surgery) gained increased authority, during which endotracheal intubation and muscle relaxation of the patient is not carried out, thus surgery is being performed with the patient breathing spontaneously. The recent study deals with our initial experience gained during uniportal NITS VATS lobectomies.

Patients And Method: Between 24.

Objectives: Different methods of open or minimally invasive thymectomies have been recommended for the treatment of myasthenia gravis (MG). We compared the results of standard transsternal thymectomy (TS) and two different types of minimally invasive thymectomies [video-assisted thoracoscopic extended thymectomy (VATET) and classic Video-Assisted Thoracoscopic Surgery (cVATS)] performed at the same department.

Methods: During three different time periods 71 patients (60 female and 11 male; mean age 31 [range, 14-84] years) underwent thymectomy for MG.
