Energy source instruments for laparoscopic colectomy

Energy vessel sealing systems versus mechanical ligature of the inferior mesenteric artery in laparoscopic sigmoidectomy

“…Other factors such as the improvement of the learning curve of the surgeon along with his surgical team could also impact. Nevertheless, Tou and al [7], in a large metanalysis reviewing energy source instruments in colectomy, found a similar difference of operating time when comparing EBVS versus standard dissection with monopolar scissors. Mean difference of 40 minutes was observed in Hübner and al [20], in a trial comparing 61 patients undergoing left-sided hemicolectomy with either EBVS, UCS or monopolar scissors.…”

“…Cost analysis were planned as secondary outcome. Price reduction was significant using EVSS (range 83$-267$) [7,18,20,21] for high caseload institution. Lower costs of material in the monopolar scissors group were out weighted by the saving performed by reducing operating costs and need for additional instruments [7,18,20,22].…”

Energy Sources for Laparoscopic Colorectal Surgery: Is One Better than the Others?

“…These advantages are even more important in difficult procedures like low anterior resections for rectal cancer or colon resection for diverticulitis. In addition, pooling of the data with regard to conversion to other instruments in a previous meta-analysis demonstrated that this was significantly more frequent necessary in ES compared to US or EBVS patients [23]. Therefore, the use of US or EBVS enables the operating surgeon to complete the operation with one device in most cases, thus avoiding the sequelae of changing instruments, saving time and reducing the risk of conversion to open surgery.…”

Infrared laser sealing of porcine vascular tissues using a 1,470 nm diode laser: Preliminary in vivo studies

“…Use of mechanical clips to seal vessels is faster, but requires exchanging surgical instruments which can disrupt the procedure, and leaves foreign objects in the body. Ultrasonic (US) and radiofrequency (RF) energy-based devices have provided rapid vessel and tissue ligation and have reduced operation times and costs for labor-intensive surgical procedures such as lobectomy [1], nephrectomy [2], gastric bypass [3], splenectomy [4], thyroidectomy [5], hysterectomy [6], and colectomy [7].…”
