Management of exuberant granulating wounds in equine distal limb: new therapeutic attempts

The study was carried out on 20 horses and 6 donkeys that were presented with exuberant granulation tissue on the distal limbs and divided randomly into two groups according to the used dressing materials. Surgical excision was done and the dressing materials were carried on the wound dressing sheets [kaltostat or aquacel]. The selection of the dressing material depends on the stage of healing and the nature of the granulating wounds. The tested dressing materials for group one are calcium-sodium alginate fiber [Kaltostat[R]], topical antibiotic spray [Tetravet[R] aerosal] and silver sulfadiazine cream [Dermazin[R]] and for group two are hydrofiber wound dressing [Aquacel[R]], fucidin[R] cream and pale sulfonated shale oils gel [Ichthol[R]]. Fucicort[R] cream and zinc oxide cream [Zincosil[R]] were used in both groups. Histopathological examination was per-formed to samples from the exuberant granulation tissue. The results revealed that the use of kaltostat and aquacel as a primary wound dressing in combination with the selected topical dressings in both groups may lead to acceleration of the rate of healing of the equine distal limb wounds without the development of exuberant granulation tissue

Efficacy of intra-and post-operative peritoneal lavage in prevention of experimental postsurgical peritoneal adhesions formation in donkeys

This study was carried out on twenty two donkeys subjected to jejunal and cecal serosal stripping adhesion induction model followed by intra- and post-operative peritoneal lavage for the first three postinduction days. The chosen antiadhesivc pharmaceuticals are dimethyl sulfoxide 20% solution; sodium chloride sterile solution containing 5000 IU heparin/liter; Ringer's lactate sterile solution containing 0.1% lavasept and 1% sodium carboxymethycellulose. From the quantitative macroscopic and histopathological adhesions score system and the clinicopathological findings insignificant differences was found in the postsurgical adhesions scores among peritoneal lavaged and control groups. The effectiveness of intraperitoneal lavage using dimethyl sulfoxidc, heparin, lavasept and sodium carboxymethylcellulose in the prevention of adhesions cannot be scientifically supported because the results were controversial and lacked any implication for clinical use. No method has gained wide acceptance and surgeons must rely on meticulous surgical technique which can minimize tissue trauma and reducing the risk of postsurgical adhesions formation

Laparoscopic reposition with abomasopexy [Janowitz method] for treatment of left displaced abomasum in dairy cows

This article describes a minimal-invasive technique for surgical correction of left displaced abomasum in dairy cows. This laparoscopic technique was first described by Janowitz in 1998 as a two-step-method. During the first part the cow is in standing position. From the left flank the displaced abomasum is visualized with a laparoscope and punctured with a trocar. Under laparoscopic control the abomasum deflates and a special toggle is inserted in the abomasal lumen. For the second part of surgery the cow is placed in dorsal recumbency. The laparoscope and a special forceps are inserted in the abdominal cavity from the ventral abdominal wall. The toggle sutures are visualized, grasped with the forceps and exteriorized. In right lateral recumbency the abomasum is positioned with the toggle sutures and each suture is threaded through a bandage and tight together. The sutures are cut 4 weeks after surgery. Field experiences with this method and two controlled clinical trials show that it is a fast and wellsuitable technique for surgical correction of left displaced abomasum. It can be performed regardless of the degree of abomasal displacement and rumen filling. Using the laparoscope a fixation of the pyloric part of the abomasum or other abdominal structures is avoided and the diagnosis of adhesions of the abomasum is possible. Further advantages of this technique are a low incidence of complications and a fast postoperative recovery of the animals
