Objective: Secure knots are essential in all areas of surgical, medical and veterinary practice. Our hypothesis was that technique of formation of each layer of a surgical knot was important to its security.

Design: Equal numbers of knots were tied, by each of three groups, using three techniques, for each of four suture materials; a standard flat reef knot (FRK), knots tied under tension (TK) and knots laid without appropriate hand crossing (NHCK).

Subcutaneous emphysema to the head and neck: an unlikely traumatic origin.

Subcutaneous emphysema to the neck represents a rare entity mainly derived from iatrogenic and traumatic origin. We report a case of a subcutaneous emphysema resulted from an intraoral injury aiming to emphasise the significance of precise medical history to identify an unlikely mechanism.

Tissue injury of the remnant liver following radiofrequency-assisted partial hepatectomy.

Purpose: To evaluate remnant liver tissue damage in a pig model of radiofrequency (RF)-assisted liver resection employing either the sequential coagulate cut (SCC) Belgrade technique using a monopolar RF electrode or the one using the bipolar Habib-4x device.

Forty-eight hours later, tissue specimens were excised from the right lateral hepatic lobe for histopathological examination and immunohistochemical assessment of tissue injury, mitosis and inflammation.
