Abstract:

The paper investigates the values of the patient’s lymph nodes measured by ultrasonography in order to determine such a critical value that would exclude the actual size of the gland exceeding the given value, which is necessary for a reliable selection of the treatment method. The uniformity of the arithmetic means and variances of the random component of the observation groups is established. Also, their probability distribution is in accordance with the normal law. Using this, a critical value for the size of a patient’s lymph node measured by ultrasonography has been obtained - when the measured value of the node does not exceed it, a decision is made with a given reliability that the lymph node size is below the critical value

Keywords: lymph node; ultrasonography; computed tomography; Bartlett’s criteria; Fisher’s criteria; Kolmogorov-Smirnov test.

World Journal of Clinical Surgery is a peer-reviewed platform dedicated to the publication of surgical case studies and other clinical research works of high quality. The journal, more so with its very own International Standard Serial Number, which is ISSN: 2766-6182 , is an authoritative source of information for surgeons, researchers and healthcare givers worldwide. The most common definition of surgery is that it refers to a medical treatment that is used to diagnose, relieve, or manage a medical condition through operational methods. It is a broad field that is concerned with the diagnosis and treatment of diseases through manual or mechanical means, injury, and abnormalities to the structure of the body. Out of critical assistance to the patient’s need of regaining function, maintaining or enhancing life or salvaging life in a life-threatening condition, surgery is the most indispensable. Key Areas of Surgery : 1. General Surgery :   This specialty deals with the management...
