METHOD OF LAPAROSCOPIC TRANSPERITONEAL REMOVAL OF A POLYCYSTIC KIDNEY IN LOW-PRESSURE CARBOXYPERITONEUM USING LAPAROLIFT Russian patent published in 2020 - IPC A61B17/94 A61B1/313 

FIELD: medicine; surgery.

SUBSTANCE: as working part of laparolift there used is sharpened needle at both ends with length of not less than 15 cm and diameter of not more than 3 mm. Under visual control of laparoscope, the pin is passed through punctures with skin and subcutaneous tissue capture in the lateral abdominal area in the longitudinal direction, selecting the most convenient traction position depending on the size and anatomical location of the polycystic kidney. Ends of the pin are fixed to ends of arc leg of the laparolift, through which, by means of a filament rod connected to an arc-shaped rigid bar with a wire attached to it, and by changing the filament length through the horizontal knee of the operating lamp, raising the abdominal wall upwards, creating a working space for nephrectomy. Working space cavity has triangular shape with highest point in projection of laparolift and maximum volume in area of renal pedicle, achieved by setting the laparolift pin in the most comfortable position. Further, the pressure of carbon dioxide in the abdominal cavity is reduced to a value of not more than 3 mm Hg and thereafter, a surgical aid is administered in low-pressure carboxyperitoneum conditions. Note here that Laparolift wire uses k-wire or Veresh wire.

EFFECT: method enables to exclude the negative effects of the impact of the laparolift introduced into the abdominal cavity of the working part on the peritoneum and abdominal cavity associated with peritoneal injuries and infection, as well as improve visualization, provide ease of operation in low-pressure carboxyperitoneum conditions by creating a comfortable space for the surgeon in the abdominal cavity, taking into account the giant size and variability of the anatomy of the polycystic kidneys.
