Abstract

In result of previous studies, we found the superior qualities of electro-welded intestinal anastomoses had created by using tools and models are suitable for open surgery.

Purpose of the stady. Was to identify promising research trends according to laparoscopic instruments usage for creating electro-welded intestinal anastomoses inside abdomen.

Material and methods. Using a full-size porcine organo-complex, special laboratory tests at the bench, the 160 probes were provided. Initially the pressure of 1,0 to 2,0 N/mm2 (1,0–2,0 × 104 PA) was applied externally to the electrodes. The electrode surface sizes were: 75 mm2 mm for conventional and 30 mm2 for laparoscopic models. Then, using AC amplitude from 200 to 500 V, frequency 466 kHz, intestinal or colon walls’ anastomosis was created. Next the connection strength of the walls was studied by hydrostatic pressure.

Results. During the small intestine fragments welding, using the model of conventional electrodes, that’s peak temperature was 83,7 ± 8,7 °C, during the colon welding – 75,1 ± 11,1 °C. The burst pressure of anastomoses were 5,5 ± 1,1 kPa, 4,7 ± 0,9 kPa, respectively.

During the small intestine fragments welding, using the model of laparoscopic electrodes, that’s peak temperature was 83,1 ± 7,3 °C, during the colon welding – 78,8 ± 9,1 °C. Burst pressure of anastomoses were 6,1 ± 1,2 kPa, 5,0 ± 1,2 kPa, respectively.

Conclusions. The possible way to intracorporeal intestinal anastomosis creation, by using the modified Patonmed EKVZ-300 power source with laparoscopic instruments, is a reduction of electrode’s area and modifying the impulses’ parameters.
