Percutaneous liver biopsy is the gold standard for obtaining a sample of liver tissue, however some patients have contraindications to this method. In these situations, a sample of liver tissue must be obtained by another approach, opting for laparoscopic or video-assisted liver biopsy. This technique allows an accurate inventory of the cavity, leading to a good assessment of the liver parenchyma without increasing the risk of bleeding. The aim of this study is to systematize a video-assisted surgical technique capable of obtaining a sufficient sample of liver tissue by means of a biopsy performed with a Trucut needle. The needle will be introduced by an adapted device that will allow the sample to be obtained by minilaparoscopy followed by hemostasis of the parenchyma without using additional trocars. This study is of diagnostic accuracy and patients were recruited who underwent abdominal video surgery and who presented moderate to severe steatosis. Patients are randomized into two groups: laparoscopic liver biopsy technique (n = 10, control group) and minilaparoscopic liver biopsy technique (n = 08, experimental group), with no statistical difference regarding gender and type of surgery. The experimental group had a significantly shorter time compared to the average procedure time (p = 0.003), biopsy time (p = 0.002) and hemostasis time (p = 0.003). The mini-laparoscopic biopsy technique using an adapted device proved to be capable of obtaining sufficient tissue sample, in a minimally invasive manner and in less time.
