Background
Many devices are available for vascular control during laparoscopic colorectal procedures. Ultrasonic coagulating shears (UCS), vascular staplers, titanium or plastic clips, and electrothermal bipolar vessel sealing (EBVS) are currently used according to the surgeon’s preference. This study aimed to compare EBVS Ligasure with UCS.
Methods
We report the outcome of 200 consecutive unselected patients who underwent laparoscopic colorectal resections of which 100 were performed with EBVS Ligasure (from September 2004 to December 2005, group 1) and 100 with UCS harmonic scalpel (from December 2002 to June 2004, group 2). Only the following three types of operation were performed: right colectomy (RC), left colectomy (LC), and low anterior resections (LAR). Emergency procedures have been excluded. The same attending surgical teams performed or supervised all procedures. Operating time, blood loss, complications, and postoperative hospital stay were investigated.
Results
Age, gender, previous surgical abdominal procedures, and ASA risk were similar between the two groups, as well as was the percentage of malignant cases (74% vs. 71%, respectively). There were 32 vs. 37 RC, 50 vs. 47 LC, and 18 vs. 16 LAR in groups 1 and 2, respectively. There was no mortality in either group. A conversion to open surgery and two major complications occurred in group 2. There were no statistically significant differences in mean operating time (111 vs. 133, 140 vs. 176, and 153 vs. 201 min) and in the mean postoperative hospital stay (5.2 vs. 6.1, 6.5 vs. 7.1, and 6.8 vs 7.3 days) for RC, LC, and LAR between group 1 and 2, respectively. We do report interesting data about statistically significant differences in the blood loss: 115 vs. 370, 150 vs. 455, and 185 vs. 495 ml for RC (p < 0.001), LC (p < 0.001), and LAR (p = 0.002) between group 1 and group 2, respectively.
Conclusions
In our laparoscopic colorectal experience, EBVS Ligasure has proven safe and effective in vessel sealing. Patients in whom this device was used had less blood loss and slight advantages in operating time and postoperative hospital stay.
