METHOD OF DETERMINING POSSIBILITY OF PERFORMING LAPAROSCOPIC CHOLECYSTECTOMY FROM SINGLE TRANSUMBILICAL ACCESS Russian patent published in 2016 - IPC A61B1/313 A61B5/107 A61B17/00 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, specifically to abdominal surgery. To perform laparoscopic cholecystectomy from a single transumbilical access, method comprises determining dimensions of anterior abdominal wall. Point A is found on anterior abdominal wall in a frontal plane as middle of distance between point, defining right lower edge X of rib, and a point of middle line of body at level of line which connects lower points X of ribs. Point C is found in a sagittal plane in centre of distance, defining height of anterior abdominal wall at level of boundary of epigastric and mesogastric region. Point D is defined as point of intersection of middle line of human body and line, connecting lower edges X-x of ribs. Navel is marked with point B. Distance BC is calculated by formula: BC= $$\sqrt{A{C}^2+A{D}^2+D{B}^2}$$ , If BC is more than 30 cm, performing laparoscopic cholecystectomy from a single transumbilical access is not possible.

EFFECT: method increases accuracy of determining possibility of performing laparoscopic cholecystectomy through a single transumbilical access by determining laparometric parameters.
