Laparoscopic microwave ablation of human liver tumours using a novel three-dimensional magnetic guidance system

Abstract

The AIM™ guidance system is an effective adjunct for laparoscopic ablation. It facilitates a high degree of accuracy and a good first-attempt success rate, and avoids the line of site interference associated with infrared systems.

Laparoscopic microwave thermosphere ablation of malignant liver tumors: an initial clinical evaluation

“…The morbidity in these studies has ranged from 0 to 60 % and mortality 0-2 % [6,[19][20][21]. The current study, with no morbidity or mortality via a predominantly laparoscopic approach, compares favorably with these reports.…”

“…In the literature, different authors have reported on open [7,[16][17][18], percutaneous [6,19] and laparoscopic [20,21] applications of MWA for various malignant liver tumors. The morbidity in these studies has ranged from 0 to 60 % and mortality 0-2 % [6,[19][20][21].…”

Laparoscopic microwave thermosphere ablation of malignant liver tumors: An analysis of 53 cases

“…The morbidity of MWA ranges between 0–60% and mortality 0–2% in the literature where the procedure was performed via an open , percutaneous , or laparoscopic procedure for various malignant liver tumors. Our results, with no mortality and 11% morbidity via a predominantly laparoscopic approach, compare favorably with these reports.…”

Image-guided surgery

“…There were 45 ablations performed on 34 tumors in 13 patients, the median number of lesions per patient was 2, and the median lesion size was 1.7 cm. 56 The success rate of first-attempt central targeting was 93%; 3 lesions required 2 passes each, and targeting was independently verified by a radiologist reviewing preoperative CTs or MRIs as well as ultrasound images from the procedure. 56 The subjective ease with which the tumors were targeted were also scored, something quite unique in the literature, and again the results were promising.…”
