Lumbar muscle density as a prognostic marker of nutritional deficiency in patients with pancreatic necrosis complicated by external duodenal fistulas: a pilot study

Despite the obvious importance of traditional methods for diagnosing nutritional deficiency, it is necessary to expand the list of perspective and more sensitive methods for prevention of nutritional disorders in patients with external duodenal fistulas. The proposed method for assessing the density of lumbar muscles has an important prognostic value and allows assessing the severity of catabolism upon admission and in follow-up period.
