Objective: Research comparing patients who received liver transplantation (LT) for hepatocellular carcinoma (HCC) has produced varying outcomes regarding survival and disease-free survival. The objective of this study is to determine the factors that influence the disease-free and overall survivals of those who have undergone LT for HCC and to compare the outcomes of living versus deceased donor liver transplants.

Materials And Methods: We retrospectively analyzed data on patients aged 18 and above who received LT for HCC from 2006 to 2022.

Purpose: Open and endoscopic techniques have been described for the treatment of inguinal hernia, but the gold standard treatment method is yet to be defined. Recurrence rates after inguinal hernia surgery vary between 10 and 15%, and chronic pain is seen in 10-12% of patients. This study aimed to introduce a new surgical technique called lateral non-abdominal pre-peritoneal repair for inguinal hernia surgery.

Purpose: Airborne pandemics illustrate a significant problem in training grounds. From the endocrine surgery point of view, we scrutinized the impact of Covid-19 on general surgery residency training in our university hospital.

Methods: The number of endocrine procedure curves was forecasted using the expert modeler in a time series model from March to September 2020 based on data from previous years.

In living donor liver transplant, it is vital to perceive the hepatic artery anatomy and its variants. In the normal hepatic artery pattern, the common hepatic artery originates from the celiac artery to form the proper hepatic artery and gastroduodenal artery. The proper hepatic artery divides into right and left branches that supply the right and left lobes of the liver, respectively.

After suspecting a plunge in the operative case logs in our clinic, we wanted to explore the COVID-19 impact on surgical training side of the lower gastrointestinal procedures to raise awareness of the possible cracks in the pillars of general surgery residency. Comparing the coronavirus impact to previous years starting from 2014, we examined the procedures of our residents for their roles in the operating room. We performed interrupted time-series analyses to get a sense of the magnitude and then used a new index to identify the trend of change in operator-to-first assistant rate of experience and searched for signs of learning-by-teaching motives.

Background: Prevalence of the end-stage liver disease in the elderly patients indicating a liver transplantation (LT) has been increasing. There is no universally accepted upper age limit for LT candidates but the functional status of older patients is important in pre-LT evaluation. This study aimed to examine the impact of older age on survival after living donor liver transplantation (LDLT).

Background: Low perioperative platelet count is a powerful independent risk factor for posthepatectomy liver failure. Usually, categorical effect of thrombocytopenia was taken into account; upper thresholds were not studied in depth, exclusively in living liver donors.

Methods: Living liver donors who underwent right hepatectomy were included.
