Introduction:

The introduction of new energy vessel sealing devices in minimally invasive proctectomy led to better hemostatic effect, less blood loss, and shorter operating time. At present, the available evidence from literature about the use of electro-thermal bipolar vessel sealers (EBVS) in laparoscopic rectal cancer surgery is weak where most studies are retrospective with non-homogenous patient groups.

Methods:

This is a retrospective cohort study where 40 rectal cancer patients operated by laparoscopic TME or laparoscopic assisted transanal total mesorectal excision were classified in two groups according to approach of inferior mesenteric vessels ligation (EBVS versus Clipping).

Results:

The operative time was significantly longer and the blood loss was significantly more in the EBVS group. However, hospital stay, time to oral, time to starting stoma function, and number of retrieved lymph nodes were not significantly affected by the method of vascular control.

Conclusion:

Both methods for control of vascular pedicle during minimally invasive rectal cancer surgery are safe, as such it is at the discretion of the operating surgeon to which method to use. Prospective well-designed trials are awaited to provide stronger evidence.
