“…Finally, the catheter was connected to a 50 ml syringe d and an analogue manometer e with the aid of a 3-way inlet tubing, thus forming a closed system [7,14,15] (Supplementary Item 3). The remaining segment of cord or testicular artery was subjected to further testing.…”

“…The efficacy of 2 haemostatic knots without application of the emasculator has been studied [7] but these researchers did not evaluate the effect of emasculator use on the efficacy of the ligatures. We hypothesised that: 1) Applying a ligature when using a Serra emasculator improves the haemostatic capability of the latter in open or closed castration, 2) the giant knot (a type of sliding knot) is comparable to the transfixing knot in terms of haemostatic properties, but requires less suture material, 3) adding a ligature in closed castration increases parietal tunic tensile strength and 4) the giant and transfixing knots would differ in terms of parietal tunic tensile strength.…”

The giant and transfixing knot techniques have comparable haemostatic capability and parietal tunic tensile strength, but the giant knot requires less suture material. In open castration, using the emasculator alone may produce adequate haemostasis. In closed castration, using the giant knot in combination with the emasculator increases the bursting pressure and possibly reduces the incidence of haemorrhage. In closed castration, application of a ligature may reduce the risk of evisceration.

“…To mimic a clinical setting the same surgeon performed all the knots in multiple sessions (4 specimens each) but without standardizing the tension applied to each knot when tying it. Leakage from the proximal end of the artery was a limitation encountered by Rijkenhuinzen et al [15] during leak testing. In our study we eliminated this limitation by the method used to connect the intravenous catheter with the artery.…”

“…The artery was cannulated proximally with a 22G 1-1/4” intravenous catheter (Protective®Plus) about 5 mm from the proximal knot. The catheter was connected through a three-way stopcock to an analog pressure gauge and a 50 ml syringe using a technique similar to a previously published study [15]. Briefly two pieces of 5 mm latex tubing were placed around the jaws of a mosquito forceps (Fig.…”

Parallel alternating sliding knots are effective for ligation of mesenteric arteries during resection and anastomosis of the equine jejunum

et al. 2014

BackgroundIn literature only one article describes and compares methods of achieving hemostasis in equine mesenteric arteries during jejunal resection and anastomosis, and most textbooks favor ligating-dividing mechanical devices. The latter method cannot always be used, not least because the devices are expensive and in some cases even contra-indicated. Various types of knots, including sliding knots, are widely used to provide hemostasis in laparoscopy.The objective of this study was to compare a triple ligature for mesenteric vessels composed of three sliding knots with a triple ligature composed of a modified transfixing and two surgeon’s knots.MethodsPortions of jejunum with associated mesenteric vessels were collected from 12 horses at a local abattoir. These were divided into 24 specimens containing five mesenteric arteries each. Each artery was closed with a triple ligature. In group A, a surgeon’s knot was used to tie the ligatures (two circumferential and one modified transfixing) while in group B all ligatures (three circumferential) were tied with a parallel alternating sliding knot. Both groups were divided ino two subgroups depending on suture material used (multifilament or monofilament suture material). Time to perform ligatures for every specimen were recorded and compared between groups.After closure, arteries were cannulated and intraluminal pressures were increased until ligature failure. Leaking pressures were recorded and compared between groups.ResultsLigation of mesenteric arteries was significantly faster to perform with sliding knots than with surgeon’s knots, both with monofilament and multifilament suture material. With multifilament suture material, the leaking pressure of sliding knot ligatures was significantly higher than that of surgeon’s knot ligatures. With monofilament suture, there were no statistically significant differences in leaking pressure between ligature methods. Both ligating methods were stronger with monofilament suture material than with multifilament suture material.ConclusionsRegardless of the ligature used, monofilament suture material performed better than multifilament suture material to achieve hemostatic knots. Independently of the suture material, the sliding knot is comparable or better than the surgeon’s knot in providing hemostasis, and is faster to perform.

How securely is the testicular artery occluded in the spermatic cord by using a ligature?

Abstract: Both ligature techniques are able to withstand the normal physiological intravascular pressure. The single knot loop has the greater breaking strength of the 2 ligatures tested and is less time consuming to perform and may therefore have advantages during equine castration.
