The Decision Support Algorithm for a Surgeon in Preoperative Planning of Mini-laparotomy Gallbladder Surgery from an Arbitrary Incision Site

Mini-laparotomy gallbladder surgery does not require strong technical skills and expensive equipment, but makes complex geometry of a surgical wound and imposes high standards on quality of an operative approach. A decision support algorithm in preoperative planning has been developed in order to obtain the possibility of quantitative assessment of a surgical approach from an arbitrary incision site. A set of indicators of quantitative assessment of surgical approach has been defined which includes the following indicators: localization of a fundus (neck) of the gallbladder; length and coordinates of the planned surgical incision regarding a xiphisternal joint; subcutaneous tissue thickness at the incision site. The previously implemented SurgEXPERT software package has been modified, taking into account the developed algorithm.
