Histopathological Response and Adhesion Formation After Omentectomy with Ultrasonic Energy, Bipolar Sealing, and Suture Ligation

Abstract

This study was designed to evaluate the histopathological response and intra-abdominal adhesion formation after an omentectomy in rats using the bipolar vesselsealing device, ultrasonic coagulator, and suture ligation techniques. Forty Wistar albino rats were used, divided into four random groups. The rats underwent a midline laparotomy, and a partial omentectomy was performed using a 3-0 silk suture with suture ligation in group 1, bipolar device in group 2, and ultrasonic coagulator in group 3; only a laparotomy was performed on the control group. Lateral thermal damage was examined the same day, and a piece of the omentum was left in the animals to be examined on postoperative day 15. A relaparotomy was performed to assess adhesion formation and histopathological response.

Superior Dissecting Capability of A New Ultrasonic Device Improves Efficiency and Reduces Adhesion Formation

“…Models of adhesion found reasons for an expectation of fewer adhesions, with a very significant difference in pathological adhesion scores favoring a previous version of the ultrasonic scalpel [13]. In a rat model, microscopic adhesion scores for an ultrasonic device were similar to the control, whereas macroscopic adhesion scores for ultrasonic were significantly lower than those for a bipolar device and for suture ligation [14]. More recent evaluations found fewer adhesions for a new ultrasonic device with intelligent control of energy delivery [15].…”
