About

The investigators aimed to evaluate long-term sarcopenia in patients with total and distal gastrectomy by measuring the anterior thigh muscle with USG, which is a more specific and easy method.

Full description

Sarcopenia was found to be significantly increased in patients who underwent total, proximal and distal gastrectomy compared to those who did not undergo gastrectomy in the long term.

To date, very few studies have investigated the development of sarcopenia in the long term after gastrectomy. In these studies, sarcopenia was usually assessed using BIA and DEXA. Muscle thickness measured by ultrasound has high sensitivity and specificity in determining regional muscle mass.

Patients who underwent total(n=20) and subtotal gastrectomy(n=35) and patients who did not undergo gastrectomy(n=35) were included in the study.

Ultrasonographic measurements Anterior thigh muscle thickness of the dominant side was measured at the mid-point between the anterior superior iliac spine and the upper border of the patella. Transverse measurements were obtained between the outer fascia of rectus femoris muscle and the periosteum of femur. Sonographic thigh adjustment ratio (STAR) was calculated by dividing the anterior thigh muscle thickness (mm) by BMI.

Functional evaluations Grip strength was measured with an electronic hand dynamometer. Three repeat measurements were performed from the dominant side and the maximum value was taken for the analyses. Chair stand test (CST) was performed while participants were asked to stand up and sit down from a chair - without arm rest, for five times as quick as possible, with their arms crossed over their chests. Three measurements were performed and median values were taken for the analyses.

Diagnosis of sarcopenia The ISarcoPRM algorithm was used whereby the diagnosis of sarcopenia was established if low muscle mass (i.e. STAR values <1.4 for males and <1.0 for females) was combined with low grip strength (<32 kg (males) and <19 kg (females)) and/or increased CST time (≥12 sec).
