[Perioperative augmented reality technology in surgical treatment of locally advanced recurrent rectal cancer].

Rectal cancer occupies the leading position among cancers, and incidence of locally advanced recurrences is still high despite comprehensive treatment. Combined resections are usually associated with high perioperative risks. These procedures are technically complex interventions requiring further improvement. Virtual reality technology in surgical treatment of locally advanced rectal cancer recurrence has not been widely discussed. The authors present multidisciplinary construction of the matched topographic-anatomical virtual model and virtual planning of the combined surgical intervention. Intraoperative use of augmented reality allowed specifying topographic and anatomical features of surgical area, level of vascular ligation, localization of tumor fixation points and resection borders. These data ensured safety and quality of resection. Further research of augmented reality technology and improvement of its technical aspects will improve the results of surgical treatment of patients with locally advanced pelvic tumors and recurrences.
