Background: In this study, our aim is to investigate the prognostic value of psoas muscle area (PMA) evaluation before liver transplantation (LT) in pediatric patients.Methods: Two hundred seventy-six patients under 18 years of age who underwent LT between January 2012 and December 2019 were included in the study. The patients' demographic, laboratory, clinical, and imaging data were scanned retrospectively. PMA was measured at the L4/5 level using computed tomography images. To determine reproducibility, a different radiologist evaluated 30 randomly selected patients. Results:In patients with end-stage liver disease (ESLD), PMA was significantly lower than in patients with acute liver failure (P < .001). In patients with ESLD, a weakly significant correlation was found between PMA and 1-year survival after LT (r: .251,

This study aimed to evaluate the role of percutaneous radiological treatments for biliary complications (BCs) in donors after living donor liver transplantation (LDLT). We retrospectively evaluated BCs in donors involved in 1839 LDLTs between May 2009 and January 2019 at our centre. BCs were classified according to the modified Clavien-Dindo classification (MCDC). Patients treated with percutaneous transhepatic biliary intervention (PTBI) were identified. Complications requiring endoscopic, interventional or surgical treatment (MCDC grades III-IV) involved 123 (6.6%) donors. Complications comprised leakage, n = 73 (60%); stricture, n = 36 (29%); and both leakage and stricture, n = 14 (11%). Percutaneous drainage of biloma formations under ultrasound guidance was performed in 57 donors, endoscopic treatment in 83 and PTBI in 14. Of 83 patients who received endoscopic treatment, 13 were referred for PTBI due to failure or uncannulation. Eight of 14 patients were successfully treated with PTBI. Six patients were treated with a rendezvous procedure combining percutaneous and surgical treatments. In 13 patients, no BCs were developed after catheter or stent removal. In donors with BCs, the treatment should progress from the least invasive method to surgery. In some patients, percutaneous radiological treatments eliminate the need for surgery or can guide surgical treatment.

As advanced gastric cancer often leads to obstruction or cancer-related cachexia, gastric cancer seems to have a closer association with sarcopenia than other types of cancer. Our study aim was to investigate the relationship between the psoas muscle area (PSMA) and morbidity and mortality in patients undergoing gastric cancer surgery. The data of patients who underwent laparoscopic gastric resection between November 2014 and April 2020 were analyzed retrospectively. The intervertebral disc space was verified at L3-4 in the sagittal plane. The PSMA on the right and left sides were measured separately and then added to obtain the total PSMA. This value was then divided by the patient's height (m2) to calculate the psoas muscle area index (PSMAI) (mm2/m2). The mean PSMAI of men (741.1 mm2/m2) was significantly higher than that of women (502.1 mm2/m2) (p<0.001). While there was a positive correlation between the PSMAI and BMI (r:0.352, p:0.019 in women; r:0.447, p<0.001 in men), the correlation between PSMAI and age was negative (r: -0.369, p:0.014 in women; r:-0.349, p<0.001 in men). PSMAI was statistically lower in patients with attendant morbidity (p:0.035). There was no significant relationship between PSMAI and the first 30-day mortality rate (p:0.096); however, the association between PSMAI and both the 90-day mortality rate (p:0.023) and the total mortality rate (p:0.046) were significant. In our opinion, assessing gastric cancer patients for sarcopenia and supporting them with the necessary nutrition and exercise program prior to surgery can help predict and lower postoperative morbidity and mortality rates.

To identify radiological findings of diaphragmatic mesothelial cysts (DMC) in the pediatric age group and to assess follow-up outcomes. In this study, 27 pediatric age group patients were evaluated with ultrasonography (US), computed tomography (CT), or magnetic resonance imaging due to various clinical indications and diagnosed with DMC from May 2014 to September 2018. Age, sex, imaging indications and DMC localization, volumes in the first diagnosis, and follow-ups were retrospectively evaluated. Descriptive statistics were used for age, sex, imaging indications, and volume are presented as numbers and percentages. Ages range from 5 months to 13 years. Nine girls and 18 boys included in this study. The most common imaging indications were abdominal pain, diarrhea, and obesity. The mean volume of DMC was at first 2.62 and 2.45 mL during the follow-ups. There was volume reduction in 24 cases, and no change in 3 cases. Mean follow-up duration was 22.4 months. The US imaging findings were similar for all cases, bilobular cystic lesion with fat indentation between the cyst and liver parenchyma. The typical localization and lateral fat sign are useful in differential diagnosis of DMC from cystic lesions of liver. The US is a very effective and beneficial radiological method for diagnosis and follow-up. Routine clinical and sonographic follow-ups may be sufficient for asymptomatic patients with stable cyst volume.
